[Aug 7th] Investigating battery capacity claims. First run of AMZER (EVO) complete.

Hello Google Android world, please welcome this shameful WinMo apostate into your ranks right away because I'm honestly a good guy who wants to start helping you all buy more batteries smartly as, when it comes to capacity claims of everyone other than HTC that I know of so far, you are in a sea of lies and gross exaggerations. I know this from publicly testing ten batteries for the HTC Touch Pro2/Rhodium/Tilt 2, batteries from the same factories that stamped out many of the third party batteries being sold for the N1, including batteries made by Mugen and Seidio.
As of now for the N1 I have tested the OEM which is rated at 1400mAh, two Seidios and an oversized Cameron Sino. At a 250mA current over a discharge from the phone's charging cutoff down to the phone shutdown cutoff (~4.14V and 3.5V respectively), the OEM clocked in at 1357mAh, or 97% of its claimed capacity. That is the best claimed versus actual figure I've seen so far (update: except for a new TP2 2150mAh), though on par with the Touch Pro2's OEMs which I tested, also in the mid 90s. So I say hello a little short on information, inviting any of you who want to help find the truth to let me borrow your batteries to test after which, as I've been doing with the TP2 crowd, I would fedex them right back. Also the information I can bring to the table you can use to get an idea of what to expect from their N1 counterparts.
How this works:
I am using the Computerized Battery Analyzer III. The software which is somewhat sophisticated plots out milliamp hours (mAh) burnt over the descent of voltage from 4.14V to 3.5V, the level of voltage in the batteries at which point the HTC/Google Nexus One and the Touch Pro2s decide to stop charging itself and decide it's time to turn themselves off because they're too low on juice. The CBA software plots out data in graphs, PDFs, CSVs, the whole deal. I hook the batteries up to the CBA which is plugged into my computer. With the software that came with the CBA I have the CBA test the batteries at 250mA, a current in the neighborhood of what the average user would average were he to do his thing (including having push-mail fired up with the screen on bright, downloading and browsing rss feeds, the occasional call, the occasional call being recorded etc) without interruption. Looks a little like this:
I'm not Colombo out to get the third party guys that exaggerate their numbers a little bit nor am I here to rewrite Wikipedia's take on capacity calculation industry standards. You know what? Scratch that, I'm starting to hate these guys, lying and overcharging way too much. If you're a manufacturer or a battery company sympathizer and want to break my balls about voltage cutoffs, read this simple explanation which I feel sums up our position well.
Tl;dr? This is to supply you with information that will help you choose which battery to buy. And to hurt the crooks.

Updates:
August 7th: After doing a dry run I ran the AMZER 1800mAh for the EVO. So far it's in first place for being the biggest ripoff on the gallon. First place.
August 5th: Received Carl's AMZER 1800mAh for EVO, doing a dry run discharge now, hopefully get some data for you tomorrow morning.
July 28th: Finished Carl's Seidio 3500mAh for EVO 4G.
July 6th: Completed round one of EVO stock (John Doward). Got the coveted Amzer 1800 and a Seidio 3500, both EVO, en route thanks to Carl Willi.
June 12th: Completed first run of a Mugen 3200mAh for the Hero. Both disappointing and unsurprising. Most cost ineffective battery I've tested.
June 11th: Jasper and Dan's batteries on the way back to them. Thanks again. Hey, Mugen 3200 for Hero and EVO 4G stock on their way! Hey, just got the Mugen. Charging.
June 10th: Completed testing for a no name Hero battery and the stock Incredible battery with the EVO 4G stock on its way. Nice. Returning those batteries to my man Dan and my other man Jasper. Hey, anyone wanna send me that Amzer 1800 for the EVO? Please?
June 7th: Just ran test number one of a no name oversized Hero battery. Underwhelming. Almost done with second test.
April 26th: Ran the Seidio 1600 again after deep cycling a bit (got worse). Got some press!
April 16th: Mailed back Wade his oem 2150 yesterday, today will mail Sean's bad Mugen back to Mugen so he can finally get a damn refund, also mailing back Roto his Cameron Sino 2400 as the testing's done. Currently experimenting with a high then low (repeat 3x) current thing with Roto's Seidio 1600 to see if it produces a more flattering result (his idea). Much obliged fellas.
April 15th: Latest test of a Touch Pro2 HTC/OEM 2150mAh scored 2150mAh on the frickin' dot! Not an N1 battery but just goes to show that if you don't like being lied to, go OEM. Finish oversized Cameron Sino.
April 14th: Was going to have another run of the 1600 ready for you but the god damned windows update forced a reboot last night. Argh. Anyway, just got a Touch Pro2 2150 HTC/OEM battery. Though it's not for our phone, it's worth knowing whether or not HTC can maintain its batting average for its oversized batteries so this will yield important information for you folks. Friggin' windows updates. What the hell is that, Microsoft, forcing reboots? Oh, easily disabled if you hit start > run > blahblah.msc > whatever > whatever? FU MS. /rant
April 13th: Finished first run of the Cameron Sino 2400mAh, weighing in at 2025mAh. Nothing to write home about in terms of a company not exaggerating about their capacity but hey, that's a pretty good price. Unlike the oversized Seidio 3200 this one does come with a back door whereas Seidio is too cool to hook you up with that.
April 12th: Rotohammer's Seidio 1600mAh has arrived, charging. First run of Seidio 1600 an unsurprising disappointment. A Cameron Sino 2400mAh also arrived (thanks Roto) and is just about fully charged for its first run.
April 9th: In a continued effort to outdo himself Rotohammer just ordered a 2400mAh-rated Cameron Sino, on its way to me. Lucky I got his attention. Extremely helpful. Thanks.
April 8th: N1 Seidio 1600mAh should show up today, thanks to Rotohammer.
April 3rd: Finished Seidio 3200mAh, five runs. Learned that it's rated slightly more honestly than Mugen but is the most expensive battery per tested amp hour. Still, highest capacity. I got a new and fast and really badass server and now have a our own forum which you can fire up at forum.batteryboss.org. Finished the new Andida for the TP2, pretty weak, but for some of you the price may be right.
March 30th: Completed dry run of a Seidio 3200mAh. Need to test it at least two more times for conditioning and accuracy but Seidio is now in the lead against Mugen in terms of not lying so much about their claimed capacity. Good job, Seidio.
March 29th: Mugen engineers respond (see table). Rotohammer's Seidio arrived, charging now baby, yeah! Should be very interesting.
March 27th: Rotohammer's sponsoring a test of a Seidio 3200mAh, battery en route. Thanks.
March 20th: Just ran the first test of the Nexus One's OEM, not bad.
March 18th: Just ordered a Google Nexus One. I got an extra battery so the first thing I'm using this for is to prepare a battery for testing. Need to figure out if it has different voltage cutoffs, need to figure out how to present the data and what to do with my site, .. hmmm.
Copypasta from TP2 thread:
March 16th: Mugen wants me to send me another battery to test, I agreed and mailed them back Jeremy's battery. Also mailed Sean/Telek his OEM 1500mAh. Thank you both fellas. Also DeathmonkeyGTX offered to sponsor a test of the HTC 2150mAh -- thank you!
March 13th: Finished no name #2 3600mAh (2466mAh ). In search of voltage cutoffs for Touch Pro/Fuze, please help.
March 12th: Mugen has expressed interest in sending me another battery to test, I expressed willingness. And to you I express curiosity into which device to expand the testing.
March 8th:Finished round two of no name #2 and fake OEM #2. Waiting on another ebay OEM to verify authenticity and a fresh Andida courtesy of my main man Shawn Martell.
March 7th:Added intriguing head to head chart matches.
March 6th:Completed a few more including fresh standard legit OEM, also discovered two counterfeits.
March 2nd: Completed no name #1, cheapest per mAh so far. Dropped Jason's battery off in the mail as promised.
Feb 28th: Completed tests of the Seidio, mailing it to jasonweaver.
Feb 27th: Just received Seidio 1750mAh from jasonweaver in addition to 1500mAh no name ebay cheapo. Nice.
Feb 27th: Mugen 1800mAh testing completed, table updated. Thank you very much jcr916 who bought the battery and had it shipped to me, now I'm going to mail it to him.
Feb 22nd: Thank you jasonweaver and jcr916 who are hooking me up with a barely-used Seidio and a brand new Mugen 1800mAh respectively. Those test results should be interesting as from what I've gathered those two brands have the best reputation and are priced accordingly so let's see if they deserve it.
Telek and I just laid down some dough for five more batteries this weekend. So I'll have a lot of testing to do shortly. Stay tuned for the results!
Testing hardware:
I am using the West Mountain Radio CBA III (Computerized Battery Analyzer) which you can buy along with some toys from these guys for $149. I bought something else from them, didn't like it and they offered to shave the cost of the thing I didn't want off the price of the CBA III without even asking me to return it. Good people. The CBA III is the most accurate and reliable device we could find for these testing purposes and we spent many hours arriving at the final testing procedure. No corners cut. There is no indication whatsoever that the results it's produced are inaccurate, certainly not relative to each other given its consistency. All testing procedures were identical including the current of 250mA, starting voltage and bottom cutoff (4.14V and 3.5V respectively, the top and bottom cutoffs of the Touch Pro2, which I use to charge the batteries with original HTC wall charger). The 250mA current may be a little high and won't produce as flattering a result versus a 100mA current, but it's both a normal current we burn when we're doing stuff on the phone, it keeps each of the three tests inside six hours usually and most importantly we use that current on every single test of every single battery so this is a standardized test. Finally the OEMs get 95% of their claimed rating on this current so we believe that that current is the sweet spot to supply you with information to use to buy your next battery.

Want to help?
First I'd like to thank Sean Graham, Jeremey Riley, Jason Weaver, Shawn Martell and Wade Woosley who've decided to do the following for me with TP2 batteries:
The next time you decide to buy a battery, hit me with a PM first so that I can give you my address. Have the battery shipped to me, I'll test the sucker then I'll hit up FedEx and get it to you asap. I have to test the battery at least three times for posterity so give me three or so days to shoot it over to you. I'll write a bit about how grateful I am you decided to help this project, yada yada, and we'll all be happier as a result. This is very valuable information and I know the batteries are also valuable to you so just borrowing your brand new battery for a little while, I realize, is a tall order. But that's a great way to help everyone out without spending a dime. I'll cover the postage to get it to you, I'm not asking for donations, I just want to run the damn tests.
Already have a third party battery but want me to test it anyway? Yes please, I am still interested in used batteries, including used OEMs to get an idea of longevity.
So once I survey the scene for shopping links I'll use this third post to list the batteries on my Christmas list.

Interesting post. Keep it up, love the idea behind this. Is it possible for you to determine how long before the n1 battery goes below 60% of its capacity by chance? and is there anyway to best optimize them for longer life?

This is a great reference. thanks
Do you think you can use your machinery to test the difference between two OEM batteries, running different kernels? For example this Undervolted kernel by Kmobs, a lot of people would be interested in seeing hard stats in the difference in battery useage over the stock kernel.

Thanks! As I said I am brand new to Android so I can't tell you what software to use on the phone, including roms and screen brightness managers, to make a single charge go another few miles. I can however, and this may have been what you were asking, tell you that the more you use the battery at lower charges, like below 30%, the faster you'll eventually wear it out. So the more you charge the better. Another thing I can tell you is that the hotter the battery runs the sooner you'll kill its longevity. So heavy things like tethering and youtube for extended periods will lead you to having to buy another battery significantly quicker than if you ran up your miles (milliamp hours) on lower currents. For individual discharges, one thing you may not know is that when the phone is on 3G and you're getting a weak signal or the phone, in GSM world, is on 3G but can only find itself an edge tower, the phone beefs up its transmitting power a lot. If you don't need 3G, especially if you're in a rural area where your signal isn't always strong or you're not getting any 3G (or in an unlucky corner of your office), maybe flip off 3G. I don't know if there's a setting for this on Android like there is on WinBlow but keep your wifi power setting on the lowest unless you know its affecting your wifi negatively too much.
Whenever you've got a data connection open, you're losing a lot more juice. So if you care more about your charge lasting than you do about constant immediate emailing, really frequent RSS updates and so on, go easy on the frequency so that you're using data only when necessary. If you go that route, remember to change all your synced stuff accordingly otherwise it won't help much if you switch your Gmail cycling down to a half hour but forget to turn your Facebook syncing off immediate.
There may be something like this for Android and if there is someone please mention it, but for WinMo, WMLongLife by Chainfire, author of WMWifiRouter, is a radio management program that very smartly decides when to ramp up and down to and from 3G and when to kill the data connection. If something like that does not exist and you're a programmer, check the thread for inspiration. Great if you want to save juice without devoting your life to toggling 3G all the time yourself.
Back to heavy use, if you do have a spare battery, I would advise designating one of them with a sharpie to be the battery you use during periods of your life, like watching videos on a long flight or running GPS software (especially Navigation since it uses not only a lot of processor and does the GPS math but it also uses data) when on road trips, even and especially if you've plugged it in to your cigarette lighter, go with the designated batter for those purposes, that way you can preserve one good battery to make it through a long day of work with no problem without much degradation. Your other battery will wear out faster of course, so for that consider a cheapo no name which, once I get my hands on some cheapo no names, you can buy wisely from information I give you. Don't trust their information, their ratings have no bearing on reality whatsoever. I'll give you actionable data as soon as I can test them.
Third party standalone chargers = BAD idea. Odds are, and certainly if the charger has two pins instead of four, that it gives a constant current charge unlike the OEM which goes hard when it's safe (when the battery's got empty room and is not hot) and then scales back when it senses that it needs to. That means the OEM charger that came with your phone or your phone itself when you plug in another source whether it's the wall charger or USB, or a standalone if you find one that's definitely HTC. The constant current chargers give a weaker charge than it could during most of the charge and then too strong a charge during the final clip. So that way, even though it may fill the tank up all the way, it takes longer to charge and it will hurt your battery's longevity. By how much? Can't tell you, but because of the threat of one of these dinko chargers not even having something to detect the cutoff voltage, ... bad idea, don't trust them unless you're using it on a $6 cheapo.

And thank you.
When I test batteries with this thing, I charge the battery and hook it up to the tester, not the tester into the phone to see what's doing with the battery as its being used by the phone. So I'm not testing to see how much different software, whether it's a strobe light program, HTC Sense, a custom rom or an underclocking mod, let you get the same happy phone experience while putting a lighter load on the battery. Rather I hook the thing up and tell the tester what load to put onto the battery (I use 250mA) and collect the data in the exact same way as I do for every battery I test. I'm brand new to Android and, though I'm loving it, I haven't even tried to root it yet, let alone experiment with different kernels.
From my experience with WinMo custom roms, I have never found a custom rom that had more battery drain than it would to its stock counterpart -- if that counterpart was running similar things like Sense instead of the old TouchFlo. I imagine your chefs or whatever you call them are pretty competent when it comes to making battery tweaks and trade-off decisions, however some roms will likely burn more rubber in order to deliver you more eye candy. In my old world there are barebones roms that have everything stripped down just to the point where the thing can boot, thereby delivering the best speed, most free ram, program stability and battery performance. Were I to flash one of your custom roms, once I got over my eye-candy phase at least and prioritized battery performance, I'd go for the new kernels with the least frills and install the frills myself as needed.
So I got my N1 last Friday and was immediately addicted, wailing on the thing, wishing I had immediately gone Android the moment it was first released instead of trying to run messy ported on my WinMo phone which is now collecting dust. That phone, parenthetically, takes a 1500mAh battery whereas the N1 takes 1400mAh. In spite of that, and in spite of the N1 having a larger screen, crazy fast processor and just being much more badass in general, lasts significantly longer than the WinMo phone on a single charge. Both are HTC phones so, unless the screen technology is really a whole lot different, to account for that I can only account for it with superior software. It's been so good to the point that I have been unsure that this project would get much attention from you folks than it's been getting from the WinMo crowd as they may be much more starved for battery information than you.
I love this thing.
If any of you have more advice than that please dump it here.

Mugen
I'm not surprised by the issue with The Mugen Power battery. I've had problems with them in the past.

I prefer to see a test done on a customers battery, not hand selected units from the manufacturer.

I felt the same way! And since I've been a Linux user for 15 years, It feels sooo good to be fully Microsoft free!

Damnit damnit, Mugen asked me to test another in case the one they sent was defective, asking that I mail it to them first, and I went ahead and mailed it to them, figuring I had enough data, and this not occurring to me. I didn't send back the counterfeits because I wanted to hang onto evidence for who knows what but it never occurred to me that whoever cooked up their batteries might have actually labeled them with different ratings. That is absolutely stunning. At least we've got the picture you took. Ouch man, that would really have pissed me off if I had bought a battery from a company I thought was reputable and saw that -- on top of the suspiciously underwhelming performance that led me to dissect it.
Still haven't received anything from Mugen, going to follow up with them. Also just let the guy know who bought that battery for me to test to get in on your discovery to find out how he wants to handle this, assuming they send me another. Other than saying they would I don't know why they'd bother.
Thanks for that, huge help, though also a huge disappointment.

dude! I love this thread I've always been careful when it comes to batteries, bought the nexus seidio 2800 mah battery and I can say there is no way I'm getting double life that they claim.
That should be the next battery to test out even though they only have the 3200 mah one now.
-Charlie

Let Mugen do the right thing and replace an under performing unit. If they want to play games, I'll have 10 people each buy a Mugen battery, I'll send them to you for testing, then open each of them up on video. If they try to deceive me, I'll setup a website dedicated to exposing any fraud.
Rule: Never piss off a geek with resources to prove a point.

Thank you so much for your post. I am truely learning alot from you and thank you for the advice. I will be sure to follow them trust me. I got two questions though, do you think its best to charge your phone off or on? Also my battery was at 15% while on a call then I plugged in. After about 10min I hang up and now its charging while on, its been 12min and so for its at a whopping 106* F, really hot..is that normal? I know heat is bad, but I can't do anything to fix it.

What do you mean standalone? i bought a motorola phone charger because the US pins don't fit here, i did notice the output is lower, so i expect long charge time. Is that still going to have the same problem not throttling it down at the end.
I suppose my best bet is a pair of pliers to bend the htc charger pins to fit in our wall sockets.
Also, in regards to heavy, for example navigation+ music in a car. Does having it plugged in to power help with that? what happens when it is simultaneously charging and discharging? I also suppse a good tip is to place the mount in front of an air-conditioning vent too, if it is a warm day, the phone will get super hot in minutes, but if you are air con-ing, it will stay cool.

Charging the battery and using the battery both create heat. That said, the total heat you'd get from charging during casual use of the battery should not be great enough to warrant the nuisance of not being able to keep your phone on until you finish charging it each time. But 106F (41 Celsius) is indeed whopping hot and, according to not necessarily precise software tests I did on other HTC devices, that is the neighborhood of heat at which the phone eases back the charging current to the point where the phone may either charge at a current about even with what your phone is burning, leaving it without any net gain while running at too hot a temperature for the health of your battery or it will begin to drop the charging current toward zero so that your phone is discharging, waiting until the temperature simmers down until it turns the juice back up.
But what the hell is causing this if you didn't have things like wifi and GPS and streaming video going while talking to someone on your earpiece at the same time? Could be a runaway process, something whacky with something software related, something wrong with the battery, something wrong with the phone or something messed up with the charger. Since you plugged the phone in and didn't use a separate third party charger into which you plop the battery to charge, since the phone was involved, it's probably not the charger. My first guess would be something sketchy software-wise. The first thing I'd do is go into Settings > About phone > Battery use and seeing if anything looks crazy when it lists what software or functions are accounting for how much of the drain relative to each other. If something is burning juice harder than the screen, the good news is is that it might not be a hardware issue, might be something that could be solved with a soft reset. Could just have been a fluke. Can you recreate the problem? If you shut the phone completely off and it appears to charge without overheating, my guess is that the hardware is okay and there is no defect. And in that case, task management and auto-killing programs may be of interest.

By standalone and third party I meant one of those little cheapo things you plug into the wall, generally without any wiring, and you put the battery into it instead of charging the battery while it's in your phone. Unless it's the OEM, there is some small danger to using these things but the convenience and cheapness, if you use multiple batteries, may make it worth using anyway, though I'd keep your OEM battery away from it and only use cheap third parties in it.
I'm 80% sure that as long as your phone's involved, meaning the battery's in the phone and something is plugged into the phone to charge it, if you use a weaker charger .... no I'm not 80% sure, let me ask Telek first. But if you've got an outlet that packs a voltage that the charger is indicated to be able to handle, typically 110-220 volts or in that neighborhood, then it's just a matter of getting the thing plugged in (safely) whether you buy a cheap adapter or go nuts with paperclips.
When it's charging and discharging, that's two things heating it up, but I'd be surprised if a serious AC made enough of a difference to make it worth moving the phone to where you otherwise wouldn't mount it. In spite of the extra heat from also charging the phone, running it on a low charge is also not great for longevity purposes but I think, I'm speculating, outweighed by the heat. If your battery's running in excess of 40c, that's not an ideal situation, but hey, you gotta drive sometimes and not devote your life to air conditioning alignment and plugging and unplugging your car charger constantly. I've done enough speculating -- Telek's the expert on this, let him weigh in.

But 106F (41 Celsius) is indeed whopping hot and, according to not necessarily precise software tests I did on other HTC devices, that is the neighborhood of heat at which the phone eases back the charging current to the point where the phone may either charge at a current about even with what your phone is burning, leaving it without any net gain while running at too hot a temperature for the health of your battery or it will begin to drop the charging current toward zero so that your phone is discharging, waiting until the temperature simmers down until it turns the juice back up.
But what the hell is causing this if you didn't have things like wifi and GPS and streaming video going while talking to someone on your earpiece at the same time? Could be a runaway process, something whacky with something software related, something wrong with the battery, something wrong with the phone or something messed up with the charger. Since you plugged the phone in and didn't use a separate third party charger into which you plop the battery to charge, since the phone was involved, it's probably not the charger. My first guess would be something sketchy software-wise. The first thing I'd do is go into Settings > About phone > Battery use and seeing if anything looks crazy when it lists what software or functions are accounting for how much of the drain relative to each other. If something is burning juice harder than the screen, the good news is is that it might not be a hardware issue, might be something that could be solved with a soft reset. Could just have been a fluke. Can you recreate the problem? If you shut the phone completely off and it appears to charge without overheating, my guess is that the hardware is okay and there is no defect. And in that case, task management and auto-killing programs may be of interest.

Exactly my point. What the hell could be causing it. Today I did a master reset once more, mainly angry with how things where running. Its fast again and so far I have not tried reproducing the situation as yet. I only use GPS for 5min total, mainly for directions. But I'm curious though, I had requested another battery from HTC because the one that came with the phone was losing charge too quickly(10% in hour). So far the new battery was working alot better, but now its the same. I keep hearing people say they get day and half of battery life with regular use and have 3G on. Yet my battery won't pass a day(by night its dead). I only have certain things like news and weather running and refreshing every 3hours to 6hours. I don't have twitter, facebook running or nothing like that. The screen is on auto and it happens wether 3G or EDGE is on. Only 2 hours more with EDGE. Am I doing something wrong? I feel like a complete ediat with two batteries.
I followed all advise, even turn it off during charging. Letting it die completely, tried 4 times this week. Its a regular thing letting it die completely since by the time I'm home I don't charge right way. Mainly because I would be expecting calls. My only option seems to be root unless you can shed some light. I can get a day or more if I leave the brightness on low, no internet or EDGE or no browsing and email syncing, don't fool around with my phone, with only a total of 20min calls during the day. Seems ridiculous to do that since others do ALOT than me and get better battey life. I feel like buy 2 more batteries now..its driving me crazy.

Well sucks. Sorry man.
So you did a hard reset, restoring everything to how it was out of the box, and it still sucks. This might be a longshot but do you happen to be in an area where you typically don't get a full signal? ... and could you see what happens if you go to Settings > About phone > Battery use? It might reveal clues though if you did a hard reset and it didn't help, that suggests some kind of hardware problem I hate to say. Download a battery monitor app and see what kind of temperature you get when using the phone normally. If it's not that high but the thing drains fast, then maybe it's the battery, secondary to what could initially have been a software problem that worked the battery so exhaustingly that it's now behaving like this without the software problem.
That's right though, what people are saying, at least for most of us; I am getting so much better life than I used to on my WinMo phone, free at last. I used to have a second charger, one at my desk, the other by my bed. Not necessary anymore. I bought a spare battery but I haven't had to use it yet. Only used it to run tests for this project.
Any chance you're still under warranty? Don't lose hope just yet man, we might be able to get out of this. Check that battery use thing.

Well so far its been 1hr 32min since I turned it on. I made 5min call and sen a few texts. I'm 94% now and this is what battery use is showing:
Voice calls 39%
Display 29%
Cell standby 7%
Android system 6%
Phone idle 6%
wifi 4%
Gallery 3% (WEIRD, have not went in there)
Android OS 3%
Google 2%
Current temp: 86.9*
Voltage: 4.0.84v
I took some pictures of it. Please note, to take pics I had to plug in via usb, using the SDK.

Lets have some fun!
I found a brand new Seidio 3200mAh battery from when I had a Motorola Q, and since I have no use for the Q or Verizon, the battery is just screaming "Open Me Up!"
View attachment 299144
Heres whats inside: 3 unmarked cells that are 32x48mm.
View attachment 299145
Compare that with the aprox 52x42mm N1 battery, we can do some math:
Code:
32x48 x
------ = ----- x=940mAh/cell * 3cells = 2820mAh total
52x44 1400
Of course this is just an approximation. The cells should be 1066mAh each, and they very well could be. I'm happy to see 3 cells in there
The new Seidio N1 battery is 52x44mm 9.5mm thick vs 4.75mm thick for the stock battery.
Simple math here, I bet theres two 1400mAh cells in it Although, they do sell a 1600mAh battery, so If thats true, then this battery could have two 1600mAh cells in it.
I weighed each cell in grams:
Code:
N1 1400mAh 30g
MQ 3200mAh 56g
N1 3200mAh 58g
N1 2400mAh 51g
Edit: Added Cameron Sino 2400.
Accounting for packaging, It sure looks like the two 3200mAh batteries are really 2800mAh.
Lets assume thought that Seidio has higher capacity/gram batteries. This will be proven when it gets tested by d0ugie.

I'd contact tech support because Doug is probably right. You have to have either a hardware or software problem that is causing your phone to drain your battery (like GPS is always on, even though it shows it is off).

Is Gallery is activated every time you look up contacts and used for the background?
I think you have your phone searching for signal all time. Go into the wireless settings and click the Only use 2g networks. Only turn it on manually when you want to use 3g.
Tell us how your battery is after that. I suspect you spend some time in areas where the phone is boosting power to get a good signal and its causing battery loss. (BTW, you only get a few hours with the screen on)

Maybe you could try using the phone during a typical day, then posting your battery results after 8+ hours of use... that should give us a better idea of where your drain is coming from, but if it is still inconclusive I would still say you should contact tech support.

Why no smartphones with HUGE batt?

These days smartphones have gotten plenty small to carry normally. so why don't they beef them up with a ginormous batt and make it a selling point?
I think the SGS is the smallest big screened smartphone. If they were to make it Evo sized, double the batt life and sell it as a completely different phone, that would be great! I mean I would think it would be some major bragging right to say "our phone has 200% the batt life of the next best phone".
10 hours of full 3G web browsing/GPS/video playback
70hrs+ of audio playback
on top of all that, maximum batt life deterioration over time will be null because you'll go through MANY fewer recharge cycles.
These phones are all great, but I'm a power user and I'm always fighting my batt. We should be able to have all the bells and whistles blowing at all times.
Thanks for your time/response
Edit: the new iPod has a 3400mah batt. Coupled with the "Peal" which turns the iPod into an iPhone (albeit an ugly one), you basically get an iPhone 4 with double the batt life in a similar sized package...
Edit: I'm dead wrong about the iPod's batt capacity as rajendra82 has pointed out. It was 3.4 watt hour, not 3.4 amp hours. Sorry (for the record, the iPod's batt would be terribly insufficient as a modern phone batt in a smartphone)

The new iPOD touch has a 3.44 Wh battery, which at 3.7 V translates to 929 mAh. The Samsung Captivate has a 5.55 Wh battery, which at 3.7 V translates to 1500 mAh. Since the battery capacity is directly proportional to the volume, a battery of 3000 mAh will be twice as big as our current battery. The biggest phones today (i.e., the EVO and Droid X) only ship with a 1300 mAh battery. 1500 mAH is plenty for this phone to get through the day. Battery life is typically rated at 1000 cycles, which is 3 years assuming a full day to go from 100% to 0%. You are likely to replace the phone in 3 years any way.

Our phones do have large batteries, and as long as you don't have a bad program, have the screen on super bright, or use it as a hot spot, the battery life is going to be good enough for nearly anyone.
The captivate has a HUGE percent of the volume dedicated to the battery already, without using a non standard (non rectangular prism) battery shape the phone thickness would need to greatly increase and have wasted space.
In simpler terms, when your battery is already good for the market, a thinner phone sells more than a marginal battery lfie increase.

What about weight? Does a bigger battery weigh significantly more?

I would love to have a bigger battery or one of those battery cases like my fiancee has for her iphone. I think the above comments are spot on, but i think what companies dont take into account is how much people use their phones for on a daily basis. I dont know about you, but I use my phone a hell of a lot during the day more so than what constitutes as 'just getting through the day'. If im lucky enough to make it through till the end of the day its skirting on the red. A backup battery would be awesome to have!

Sorry, I just realized that. I must have missed the details about the ipod power.
I understand that the captivate technically has the "best" battery, but I do not agree that it will last through the day. I'm using my phone regularly to look up information, text, Gtalk, and make many calls. The phone is dead by the time I get home around 6pm (days start around 7:30am).
the iPad has a "10 hour batt life". My sister has her iPad lying around the house but she and I are much more often on our phones, so why don't our phones have a 10 hour batt life? I think its kinda difficult to use the ipad for 10 hours in a single day seeing that people usually work too. My phone is used for productive purposes usually, so it is very easy to drain it in the 4.5hrs it lasts on any day (not to mention difficult to get through an 8hr plane ride and still have juice to find your way to the hotel when you land). Last I checked, a day was at least 8 hours, not 4.5.
I also realize that they would have to ditch the rectangle/cube form factor of the batt in order to fill the space of a larger case more efficiently (something the iphone takes advantage of). I have nothing against this (or the added weight) and I don't think any other power user would care either.
At the end of the day, a captivate thats as big and heavy as the Evo is a small compromise if it'll last ALL day long and I believe there is a significant market for Android+10hr batt. Unfortunately, the obvious response to that is that I'm wrong since it doesn't exist. So I guess I'm just a crazy person then
Sigh...
Edit: I forgot to mention Virgin America has solved all flying problems with this nifty little thing called a power receptacle in each trio of seats.

There have been at least 10 different claims in the last 5-10 years from companys saying they've found a way to at least triple battery capacity.
so far none of them have made anything...

Have you ever seen those extended batteries that also replace the back cover? They look awful. It's great that the Captivate is so slim and light.
It's unlikely that enough people need that much power every day for manufacturers to implement a huge battery in every device.

Nevertheless, it would be great to have the option.
Third party batteries that replace the back cover haven't been designed by the manufacturer to take advantage of all the space available, they're just made afterwards for the (admittedly few) people who need to stay more than 12hrs without a power source.
If a manufacturer specifically made a phone to accomodate a larger battery, the uglyness+volume/duration ratio would be much better.
Imagine a qwerty slider with a large battery instead of the keyboard: you could live with the additional volume and you could go on for two full days without a powersource.
Personally I wouldn't ever make it without a car charger, I keep a spare battery around in case I need it and even carry a retractable microUSB as a key holder (I use my phone as a music player, the battery drains FAST).
I'm ok with that but a large capacity batt. would let me not have to care about how much juice I have left all the time, wich would be great.

You're not crazy. I think about the smartphone battery problem all the time. It's by far the biggest drawback of a smartphone. Even if you are using it lightly, you still have to charge every night, that is smartphone 101. And yet, if my friend iwth a little feature phone texts me all day, and I text them back all day, there phone... is fine. They can bascially run it all day for three days before needing to charge when it's new. My Captivate (or any other smartphone)... constantly having the screen on? It would be begging for battery after hours. Now of course, we have vastly better batteries than the feature phone, it's just the smartphone is doing significantly more. But still, yes, there should be a way, possibly with non-rectangular batteries, to significantly (at least double) battery life at a not massive cost to form factor and size. And yes, I'm sure there is a market here as well.

Seido is in the development process for a 3200mA battery for the cappy. Won't be long before you can actually see what it looks like on their website

This may be about the captivate battery life but I think some of u are crazy. I run the hybrid r3 rom on my phone and I use it for music; GPS; internet and everything else that is normal and my battery is garbage. I'm sorry but when I buy a phone it should not be dead by like 3 pm

Bigger battery means more weight. Some manufacturers get a little more power out of the same physical size, but if you really want to double the battery, you double the size and double the weight.
Since the phones have no extra room inside, you wind up with a bigger phone.
All manufacturers are trying to balance size, weight and power. It is no coincidence that all the smartphones have near the same size battery.

Seido might make some great batteries, but if the batt for the captivate is ANYTHING like the batt for the galaxy S, its absolutely retarded and WAY too big to be practical. They basically just extended the batt brick and extended the casing with it. With the same batt cover, they could have added a whole nother batt right next to the extended batt cuz of all the wasted space.
Not a viable solution IMO. A factory made phone that has a HUGE batt would be marginally larger than the current captivate because they can take advantage of a non-traditional form factor and all the space inside.

Our Captivate doesn't have any extra space, and even the Droid X has a battery of the same size. I am just not seeing the extra space for bigger battery. There is also the weight issue.
Now if maybe the new Dell Streak will give you a monster battery in that big thing.

i agree that a phone with a super battery pack would be nice. me and my friends would always talk about if we could make our own phones what we would want and i always said something that would give me nice battery life so the idea i came up with was this
by default most phones come with a 1500 mah battery
but why not add a non traditional form factor to the rest of the case adding battery to and around the phone like in the area around the camera in the front of the phone around the side of the phone kinda like some of this battery jackets we see coming out for the iphone 4
i think it would add maybe just a built more bulk to the phone i'm still using a tilt so i'm used to carryin a bulky phone
i've always been interested in seeing super cap or ultra cap tech being put into a smartphone figuring if we can't go all day with our battery at least let us be able to get a full charge with in a few minutes ya know
i see ultra and super cap tech starting to be put in remotes were you can charge it in 1 minute to 5 minutes and not have to charge it for two weeks that kinda tech in a cell would be lovely

I, for one, would give up the cool looking indent in the back of the captivate (where the metal cover is) if they would fill that space with battery. It wouldn't increase the size of the phone (much), wouldn't make it bulgy, and I could see it giving at least 50% better battery life.
Even if the phone was blobby, plenty of people are buying Droid phones, and those things are frikin' mon calamari cruisers.

obviously they would have to make the phone a tad thicker and its already so light weight that adding double the batt weight would still keep it weighing less than an Evo

the Samsung Captivate battery is pretty beefy if you ask me, I don't know how they would fit a processor and other components in the phone if they got a bigger battery

Spare batteries for the MT4GS? Anker for the win!!

I spent less than $30 over at Amazon and got two 1900mAh batteries and a charger for them. The batteries say that they are for the Sensation but work perfectly for the MT4GS. I take lots of photos with my phone(30-40 daily),, send a 150 or more messages a day, surf, compose emails and have about an hour of total talk time per day. 2 Anker batteries takes me through the day without needing an outlet.
I can fully recommend these for our phone. I am in no way affiliated with Anker and did not know the name before I purchased the product.
UPDATE: These batteries are NOT A WIN! After a month and a half of intense usage, I am finding (with two separate batteries) that these may not get enough power to our phones and results in an error for the camera flash when no real error exists (except with the manufacture of this battery perhaps).
I am checking out new batteries. Will report back asap. I am recommending folks avoid Anker for now though. I'm still investigating this situation.
FYI: The exact error is "unable to use flash due to cold weather".
UPDATE: After a few days of trying to reproduce the flash error, I've had zero problems and lots of fun with my phone so I think we can chalk it up at most to a defective battery and not a systemic issue. I've been using the battery since with no problems. Enjoy your phones!

That's the link to the one I just ordered, it shipped yesterday, should be here in another two days. I'll definitely review after I get it.
Anker batteries in the 1900 capacity have been recommended by several here so far, and I haven't heard anything negative about them except for:
One user reports that the fit is almost too snug in the battery case. Any words on this?
Other then that - they sound like a solid win, enough so that I bought one too.

I actually purchased the set that comes with two batteries as I bought my MT4GS on Craigslist and couldn't verify the integrity of the battery it came with. The batteries for the Sensation DO fit snug but it doesn't cause any problems. I spent 30 minutes looking at that aspect. Putting them in, taking them out.... The batteries last a good while (1900mAh) and the charger seems to work well after the initial charges which are a bit longer than normal (but not much longer).
One thing to look out for is that the charging prongs on the charger have a design I have not seen before. Since it is a universal charger from Anker they slide along a rail as so that they can be used to charge various HTC batteries which may have the charging port at various different points along the top of the battery. So like the G2 or the HD2 battery could be charged in the charger as well (I've done it) because you can move the charging prongs from left to right along this rail that they slide on. So you have to make sure that you have them lined up for the + and - port on the MT4GS battery so that you're getting a proper charge and not just sitting there wasting your time.
It's a small thing and not a problem. In fact, it might be a bonus for those who have other HTC devices that it can also charge.
Congrats on your purchase. I don't think you'll be disappointed.

Chinese 3 battery combo with charger
I have been buying the spare batteries from Hong Kong/China with the slow ass battery charger for my past few devices. They are 10.95 delivered. The MT4GS and the Sensation are IDENTICAL. I spent 1 dollar more for the MT4GS and everything was exactly the same and there was no reference to MT4GS on either of the packages that arrived at the same time.
I can't complain. I always have my laptop bag with all of my techno gear spare 2A DC and AC chargers.
I can't not be connected?

It's definitely a tight fit, but it's not too bad -- it's not hard to pull out when you want to change the SIM or microSD card, for instance. It is tight enough that it doesn't fall out by itself very readily, though -- a couple days ago when I was experimenting with the carrier unlock and swapping SIM cards, I forgot to put the back of the phone* back on when I was done, and I carried the phone around for several hours without having the battery fall out or come loose. I even dropped the phone about 2.5 feet from my desk surface onto the non-carpeted floor and the battery didn't pop out.
So the fit is definitely snug -- much snugger than I'm used to in a phone battery, in fact -- and you have to press down to get the top to slide into place properly, but in my opinion it's a good thing, not a bad thing.
*That is, the "battery" cover, although it covers a lot more than just the battery, unlock my G2's battery cover, which I wish they had made the mT4GS's battery cover more like, but now I'm a bit off topic...

Good to know.
Mine came in today, and i'm watching the charge light turn purplish now as it goes from red to blue, so it should be real soon that it's done charging for the first time.
I think i'm going to restore my first solid CWM backup after rooting on my old battery, then wipe the battery stats file, power down, swap batteries, and power up to run it down. Hopefully this will get me a good calibration right off the bat.
I can't wait to start using it - this holding off until it's charged all the way the first time is killing me lol.
I'll report back in a few days how it works after the first 4-5 discharge cycles the package says it'll take to get my full capacity out of it.

Do you have to use the charger that comes with the battery to charge the battery or can you charge it as normal inside the phone? I would like to get a longer lasting battery but I certainly do not want to have to remove it from my phone every time I want to charge it.

No, it charges just fine inside the phone. The external charger is just in case you need to charge it outside the phone for some reason, like if you have two batteries and you want to charge both up for a long trip or something.

Awesome! Just picked up two MT4G Slides the other day and already I can see the battery life is going to be a potential issue. Coming from a Bold 9700 I knew I was going to run through the battery much faster, but I wasn't quite expecting this fast.

Okay, after my second day with the Anker 1900 battery, I am extremely impressed.
It's like a night and day difference. Honestly, my biggest concern was the heat issue. I noticed that my stock battery got pretty warm, and while not enough to burn me, was enough to impact the lifespan of the device and battery.
I had a theory that spreading the same amount of load over a greater range of discharge would produce less heat, and that has proven out to be true. Maybe the Anker battery is just made better, but more likely my theory was correct.
The Anker battery doesn't get anywhere near as warm with general use of the device as the stock battery did. Solid win there.
The amount of time I get with the battery before having to charge is already significantly increased, and I haven't fully broken it in yet. I'm no longer having to plan out where my next charge location is going to be and trying to ration my device usage to make sure I get to it. Now I can just go about my business without worrying about running out of juice.
Bonus points because now my stock battery is available as a backup, just in case - making the win that much sweeter.
Thanks to everyone who suggested this battery, it was definitely a great buy, and the price is unbeatable.

u think I can buy sume of those battery from amazon.com? I'm Italian, but I can't find shipping restriction section...

Good find. I might pick up one of these. Would really have liked the charger to be USB powered, though (or at least have a long cord) so I could set this on my desk next to my phone.

Evo 3d Battery
Has anyone tried the Evo 3d battery? It's rated at 1730mah and reportedly works just fine in the sensation.

I don't know if you'll find much traction for this - the anker battery has a higher capacity rating and lots of endorsement from people (myself included) who think it is a superior replacement for the stock battery.
I'd be curious, just to know, but I would recommend the anker 1900 battery for the sensation above anything else.
I wonder why you would want to know this?

Contacted Laptopmate (US Distributor of Anker) via Amazon's customer service. Turns out they have an Ebay store and an Amazon store.
Ebay store is MUCH cheaper. Found batteries and a charger for $15 less.
One thing this company does on both sites is "overlist" they will have the same product for $8.99, and $9.99 for example. I found the first eBay mt4gs battery was 11% off and listed at $14.99 with charger, I kept exploring and found it later for $11.99 - same item.
You also need to watch they have some other non-Anker batteries with varying capacity sizes that might be a bit less. YMMV.
Now just sitting back and waiting for them to arrive.

Will be picking this up for me and my friend (who has the sensation). Good find!

Just ordered two today! Can't wait...as I take lots of pictures and videos so it'll be refreshing to have fully charged batteries ready to go, on the gooooooo.....

Just so people know, it is a little bit bigger. I have a problem squeezing my body glove case on (but it does go on, barely). I'm just waiting for another case with more clearance so it fits.

That bad? Jeez...

I need a case, otherwise this phone will be abused too much. It is an expensive piece of equipment.
On a side note, I've been trying my damned hardest to drain this thing for 6 hours, and I'm only at 50%. Highest brightness game playing and browsing, and 4G has been on the whole time. Plus, I took enough pictures of my gf to get her irritated.

Tmobile phone/battery/charger warrenty replacement issues....ugh..

I bought my G2X around the end of April.
the USB became very loose and would rarely charge even when it shows it is charging after jiggling the plug to get it to work. Ive tried this with multiple chargers.
if i do get any sort of charge its no more than 10% and it discharges very fast about 1% in less than a minute. you can actually watch it drain.
the wall charger itself also does not charge, yet when i plug the wall charger USB cable into a PC USB it will slow charge.
yesterday I went to the local Tmobile store to order a replacement and the replacement phone showed up today without a battery so i still cant use it.
the new phone has been charging the old battery for hours and still has only 1%
I called Tmobile customer service and they tell me I have to choose between the battery OR the charger I cant have both, then I'm told I will have to pay $7 and change for GROUND shipping.
I explain the phone is around 8 months old, under warranty, I have insurance. and i know PLENTY of people that have had batteries shipped to them free of charge and they get to keep the old battery.
I know i can just get another wall charger from Ebay cheap but that's not the point
Im not trying to get something for free, i just want the phone,charger & battery that I paid over $500 for + insurance to actually work without me having to pay extra for it.
has anybody else had this issue?
it seems everyone else that has had battery and phone issues ( there have been plenty ) had a much ,much easier time and better experience than i am getting

That's terrible to do. Batteries die over time, and quickly when sitting idly by just waiting to be used.

I doubt that battery is sitting for very long.. if you even think about using the phone you lose 15% battery charge lol.
Im willing to bet he keeps a charged spare to swap in later in the day.
Id like to do that myself because I have never been able to make it 6-8 hours without a charge even on light use.
I love android but Im increasingly tired of the horrible battery life on every android device & Tmobile bending me over and screwing me. I read all these stories about great customer service but i always get the person that barely speaks English, replies from a script regardless of what i say and they never seem to care to offer any real help.
I want a damn phone that i can use as intended and only needs to be charged over night. sure maybe not streaming all day but at least everything else

Batteries are less than $10 on Amazon

Seriously, battery life is an issue with ALL smartphones. Look at all the ios users complaining about battery life, there are plenty. And, they can't swap batteries.
As far as T-Mobile goes, their replacement policy is no worse than any other carrier. If you have insurance as well, that would cover your shipping.

True but Ive NEVER had an android last anywhere near any of my friends Iphones as far as battery life is concerned (havent compared the newest model though). I can spend a whole day with an Iphone user and My phone is ON the chargers as often as theirs is off.
If I wasnt in love with the Screen size and HDMI out I would go back to my N1 <3
come to think of it I need batteries for the N1 & G1 as well lol

Btw, now that I'm not on Mobile, I can make a more complete response...
*puts on the old PDA Tech hat*.. yes I used to work in a T-Mobile Tier 2 PDA support... I supported Android, WinMo & Blackberry devices. Mostly blackberry, LOL, those things were terribly unreliable.... I trained on the G1, MyTouch3G, Cliq, Behold II (ugh) and Nexus 1.. though they wouldn't actually give us Nexus 1 devices to handle for some reason.
Anyway.... you can tell how old my info is now, so take it with a grain of salt, some policies may have changed.
First, insurance should cover shipping. Without insurance you pay shipping, with it you don't. If they told you otherwise, ask them when the policy about that changed. Also if you've paid shipping once in the past 30 days and it didn't resolve your problem, they are supposed to waive shipping on subsequent exchanges even without insurance.
They will NEVER send you a complete package of battery, phone AND charger all at the same time. The reason is simple: For all 3 to go bad is incredibly rare. If proper troubleshooting steps are followed, you can eliminate which one is the cause of the issue. If you cannot eliminate one of the 3 by testing at a T-Mobile store, they will normally send you the battery first.
The reason they did NOT send you a battery first was because you mentioned your charge port was loose. That's a phone issue, not a battery issue. Again, very rarely do TWO OR THREE separate devices go bad all at the same time, so you replace the one that's obviously bad first.
Now, you have a new phone and still have issues. Chances are it's the charger or the battery - but again, rarely both. Pick one. If you're unsure, then go to a t-mobile store and ask them to let you charge your phone for a bit on THEIR charger and see if you can see a difference.
Why they won't send you both, as I've said above, is it is very rare for both to go bad at the same time. Proper diagnostics (trying another battery and/or charger) should determine which is at fault.
If they were in the habit of replacing EVERYTHING any time a customer had a problem, then costs would go through the roof and your device would cost much more.
EDIT: As far as battery life... keep in mind that an original iPhone has a much slower processor than new Androids and didn't even support 3G (which uses more battery) in its first incarnation. The smaller screen on an iPhone also impacts battery life positively, whereas the bigger and brighter screens on many Android take more battery to power. Plus, Android has the capability to do much more multitasking, which leads to more processor usage. You have to be careful what apps you install because of that - or do as I do and use "Autostarts" from the market to prevent apps that believe they are special and should start up at all sorts of system events. Autostarts is much better than a task killer ever could be because it prevents an app from starting up on its own in the first place, and in the end, is a very positive influencer of battery life.

thanks for the info. Ive already been charged and honestly its not worth dealing with them again for $7 lol
as far as testing all 3 devices thats already been done. the Tmobile store tested the phone and battery and agreed it wouldnt charge over 1% and the USB is loose and needs to be wiggled to work ( if you are lucky )
the old battery has been in the new phone charging all day. It wont charge over 1%
if I plug either phone into the factory wall charger its as if I havent done anything, phone doesnt recognize its being charged unless i use PC USB or my Motorolla 950mah car charger. and again its only getting to 1% and turning off.
I explained all this to customer service and as usual i get the scripted reply. We are sorry for your inconvenience but i wont really help you blah blah
So far Tmobile customer service has been worse than Sirius and thats saying ALOT. i wish they were more like Zappos. customer service there is nothing short of shockingly amazing.
I called to say I accidentally clicked the wrong size sneakers and the rep called the warehouse, stopped the order before it shipped out. sent the correct size next day air getting it to me EARLY and signed me up to the VIP service which gets me next day shipping on all my future orders. because of that I have ordered with them many times since.
Im not expecting Tmobile to go that far but it would be nice to have what I paid for working without all this hassle and any cost

Well, I admit a lot could be done to make technical support better. However, it's an industry-wide issue, not just with T-Mobile and not even specifically with cell phones.
While it *is* possible for all 3 to go bad, you have to look at it from the viewpoint as well of the tech rep sitting in a cramped and noisy cubicle all day. 99% of the calls she gets are because people forgot their Google password and are locked out of their phone due their kid enabling pattern lock. They don't even KNOW they have a Google account in the first place! Then the T-Mobile store wipes their phone, and they wonder how to get all their contacts back.. you know, the ones safely stored on their Google account... to which they do not know the password.
And then, they get your call. You say your phone, battery AND charger all 3 went bad? If the rep were to replace all 3, she would lose her job if that call happened to be graded. Why? Not following proper troubleshooting.
It's frustrating, I know, as the customer who actually does have a problem with all 3 at the same time. But that is an outlying case. 99% of the time, only 1 of the 3 devices were actually faulty to begin with.
In my experience, customers would ALWAYS demand a new phone first, when I was pretty sure it was the battery at fault. Most of the time it WOULD turn out to be the battery as well. Batteries fail a lot more often than people suspect. Except, that by demanding a new phone first, now they've sent back a perfectly good phone, and have a refurb which could have its OWN issues.
I would almost always try to start by replacing the battery first, but most customers would shoot that down.
In your case, as I said, the loose USB port indicated a phone problem, so they started in the correct place with replacing the phone.
Anyway, back to your last post.... Yes, customer service could be MUCH better. But it is the price we pay to have affordable gadgets delivered to our door.
I remember when I was a kid in the early 1980s and my Atari 2600 died. We had to mail it off to a repair center hundreds of miles away, and it was nearly 6 weeks before a new unit came by UPS. Oh, and we had to pay return postage COD. Good thing my mother was home when the UPS guy showed up!

Battery or Charger?
When I had a problem with my battery in April, I just called customer service and the gentleman I spoke with said no problem and sent me out a new battery, with free shipping and told me to just keep the old one. I'm one of those people who have had nothing but excellent service from T-Mobile. I've know A LOT of you all have had crappy service from them and I don't doubt it at all, but I'm a lucky one I guess. If I were you I would call again, maybe a few times until you get what you deserve! Good Luck Bud.

Anker battery

My father and I both have Inspires and since I helped him Root his and do some flashing he gave me his extra Anker 1900mah battery. He had just got a pair from Amazon. This was a while ago. Well here the other day, I had my phone charging on my deck at work and had no issues with it what so ever, never really have. So I unplugged it and shoved it in my pocket. Within a minute I noticed quite a bit of heat on my leg. So I pulled out my phone and it was nolonger on and was just getting really hot. So I pulled off the case, took the battery door off and could not get the battery out. It was so hot it had expanded and wouldn't just drop out like normal. So I got a knife and as quickly as I could pryed it out. Not easy, didn't want to puncture the battery or damage the phone. Once I got it out it continued to stay hot for at least 15 minutes. So hot I couldn't touch it. If anyone is looking into this battery, don't. My phone survived without issue. But I am sure if I hadn't noticed it was getting hot, my phone would've been toast!

That sucks man! Glad you caught it when you did and no phone damage or injury. Have you contacted them about it yet? I'm curious of their response.

I'm curious as well, I've had them since January and haven't had an issue Luke that. Though one of them seems to drain faster than the other. I switch them about once a month

My father's is still working fine and I am going to give this one to him and see what he wants to do, since he was the original purchaser. We'll see, might be a while... Everyone just be careful with these, I would hate for a battery to cost me my phone.

Ive had mine for about six months and not one problem. Battery life is excellent, no heat. There are some program(s) that can heat up a phone while running. It might be something other than your battery. Maybe even your phone it self.
Good post. Let us know what you find.
Thanks, Nylo
Rooted AT&T ROM/GB233 Inspire

If you have a 1900mAh battery then it is not an Anker battery. Their batteries are only 1350. Previously they were falsely labeled 1500/1600 mAh. But they have no 1900 batteries to fit the Inspire. You have a chinese knockoff or something else.

Agoattamer is correct. You can't expect any more than a few hundred more mAh in a battery of the same size. There is simply no way to add much more capacity within the same size. Be wary of cheap batteries that claim to be more than stock, especially 1500 mAh and over.
