Is there any way to get this thing to last over 10 hours with moderate/medium usage? I mean I hate to compare, but I was able to use my iphone 4 hard periodically through the day and be at 40% around midnight, but I have to stay using my captivate very lightly after about 10pm, and I usually unplug around 12 to 1pm..
I don't want to have to sacrifice majors perks of why I switched to android just to get a full day out of it. I've tried a lot of the suggestions I'm the forums, but nothing makes a notice difference, or makes it a fame changer as to where I'll get a full day of moderate internet/media usage
Thanks in advance.

Have you tried draining and recharging the battery as other threads have suggested? I usually unplug around 9-10am and I don't get battery warning until near midnight or later.
I keep seeing people complain about the battery life constantly.. but to me coming from my bb bold it seems that the battery is lasting way longer then i expected.. first couple charges i let the phone drain down till it shut off, and then charged it 100%.. its still new to me so im constantly playing with it and changing the menus around.. i try to make sure almost everything is closed when im not using it.. cause im sure that eats battery life..

I did it once, but I booted back up the phone a few minutes after I plugged it in, will leaving it off while it does a full 100% charge noticeably increase battery life?
Do you have widgets updating frequently? How frequently? Maybe just too many updating widgets. I get about 18 hours with the screen on for 4.
18 hours also
I'm getting 16-18 hours of use with about 4-5 hours of screen time. Better than expected.
Today I used my phone as much as I used my iPhone 4 on a regular basis. My phone has been off the charger for just over 12 hours and I have 70% of my battery left.

I'm around that too, I use a black background to save power and I have about 5-6 hours of screen time and I watch a movie on it every day (treadmill at the gym)
I only get low battery around midnight
I use advanced task killer and set it to when the screen is off to kill apps, aggressive mode, I can go about 20hrs before I need to recharge. 5-6hrs screen time.

One thing about android is it has true multitasking. Combined with some apps which do NOT close properly and continue to use up CPU this can drain your batter very fast.
In the battery Info your TimeSpentAwake should be ~ the same as Display on time. If not something is not closing properly. Use OSMonitor to check which program it is and either uninstall it or make sure to kill it with task killer after using.
I have the M110S (Korean Galaxy S - I get 16-18 Hrs with moderate use, but M110S comes w/ 2 batteries so i just swap )
Yeah based on people who are getting good battery life mine is absolutely terrible. I am on my fourth full discharge. I have had my phone off the charger for 2 hours and I'm already at 87 percent. I listened to about 45 minutes of cached slacker radio and like 2 posts on xda app

Just to comment on my battery life. I got my phone saturday (2.5 days ago) and its been on the whole time with medium usage. When I got the phone the pamphlet inside said "fully charge before you turn on" and thats what I did. My battery is at 41% and the only time that I have charged it since is when I am connecting it to my PC for a very short amount of time. I have had great battery life so it is possible. I am very impressed with it.
Yes...my battery life has been good...
Screen brightness all the way down (auto brightness off) *same for the browser brightness
Screen timeout 15 secs (annoying sometimes so maybe 30 secs)
No window animations
Power saving mode off (no point in having the lcd adjust if its already as low as it will go)
I also dont have any widgets that update in the background, however i'd imagine one or two wouldnt affect the battery much
These settings have worked out for me and i use the phone moderately with 2 hourly updating email accounts.....

Battery life for me has been decent. I consider myself a moderate user and I can go from 7:30am till I go to bed at night without dying, but its close. Coming from an iPhone 2G, where with the same usage I could get 2-3 days on one charge, its a little disappointing. But it is what it is I guess. I have heard horror stories of EVO's only going 4-6 hours on a full charge, thats ridiculous.
But what gets me is all this nonsense about fully discharging before charging back up every time. These are Li-ion batteries, they are not Ni-cads, they will not get a "memory" if you dont fully discharge every time. Yes, its good the very first time, to fully charge it before using it, but after that, it doesnt really matter.
Also, one more thing I noticed. The phone will stop charging the battery the second its fully charged. So if your phone reaches 100% charge at like 2am, it stops charging at 2am and you are then going from 2am till whenever you take it off charge in the morning. I noticed this the other day. As soon as the phone told me it was fully charged, the battery icon turned into a normal battery icon even though it was still plugged in. So its possible that the phone is going for 4, 5, 6 hours off charge before you even wake up. What I do to make sure I'm at 100% when I leave, is when I get up I unplug it, use it for a minute then put back on charge while showering. Then when I leave for work, I know its fully charged at 100%.
I guess I'll be switching out phones at Best Buy today as well. Phone keeps losing 30-40% overnight (more like 5 hours max since I'm a night owl) even with everything turned off. When I do get back to a 90% charge before I leave for work at 8am, I'm usually left with 30-40% by 5pm after 15 texts or so and a few emails.
I am fairly sure all new batteries have a chip in them that regulates the power. So you HAVE to run it down to 0-5% and charge it back too 100% several times before the battery is even calibrated for use. That has to be why its 50/50 battery sucks battery is great, just let it drain and charge it again.
battery life simply not acceptable
Hey guys,
I know many people post on battery life.
Here is my situation.
I do not care about beauty, but functionality is a must.
I am in the hospital from ca 6am to 7Pm and I have Q4 call meaning every fourth night its to midnight. That is simply a fact of my life.
My requirement:
I need my phone to last for this duration without recharge.
1.)
I don't need or use widgets
2.)
I don't need or use a wallpaper other than a solid black background.
I do need and use:
the GSM radio and wifi both need to run the entire time and reception is what it is.
My applications of use:
merck manual, dynamed, epocrates the usual in my boat.
I really really want to use this phone, but battery life wise only my blackberry with extended battery and my iphone 4 can hack it.
If any of you have any suggestions on what I could do plz let me know. My last resort is carrying two batteries, but that would frankly be admitting that this phone is inferior to the iphone 4 which can hack a 20 hour usage day in my setting.
(I absolutely cannot turn wifi or 3G off both must run)
I am open to all suggestions including the task killr controversy or anything else constructive one may have. Any extended size batteries out there for the captivate?
Thanks a bunch in advance.
(Having had my secretary spend 4 hours rooting the phone and sideloading Merck manual is a testament to the pathetic entity that is AT&T by the way. If you have professional apps from an institutional subscription you cannot download the software from the market...)
PS: My secretary is not exactly a hacker so forgive the 4 hour timeframe.
I consider myself to be a heavy user!! I like to text, browse the web, listen to music (either from my own files or streaming,) check email and comment on facebook all throughout the day. I did that perfectly fine with my Bold 9700, that battery lasted a full day or more.
I had an iPhone 4 and my battery would not last my 8 hour work shift!! I either had a bad battery or who knows what was going on with that phone. I didn't even leave the apps running...the phone was nice, but that battery killed it for me. I don't understand how some people got a full day out of it.
On the Captivate the most I have gotten has been around 10 hours of use and that's not even using it how I normally like to. I stop charging it at 8:30 and my battery is 100% around 10am I'm already in my low 90's or upper 80's. I don't have any widgets updating, I have a black wallpaper, I don't have the haptic feedback on, and I sync email hourly.
Could my battery be bad?? How can some of you manage to get 16 or so hours out of it??
I had this problem once when I first got my captivate, but then it went to normal (lose ~5% overnight). Overnight I keep wifi connected and airplane mode off. I was happy, lasted 10-15 hours daytime depending on how heavy I used it, etc.
I recently ordered a two spare batteries with an extra micro usb cord as well as an external battery charger (charges batteries while not inside the captivate). I use the new microusb cord to charge sometimes too because for some reason it doesn't work with PC to connect micro sd card, and I charge my batteries mostly using the external charger.
I recently started losing 30+% overnight. I don't know when exactly (if it were apps or the new batteries, but it happens with my old battery and the new ones). I installed spareparts and battery history and tried turning off background data but I still lose this much overnight. I don't really know how to read spareparts to try to isolate an app. My daytime battery life is not drastically lower than before (10+ hours), but I think it is a bit lower than before. Does anyone know how to fix this problem?
tl;dr:
- used to lose <5% battery overnight
- got new batteries, now use external charger
- suddenly started losing 30%+ overnight, don't know why
- help please!
thanks!
I personally lose more than that overnight when I have wifi enabled. However when I have it off I lose less than 5%. So I guess I'm in the opposite situation as you.
Since you already have spare parts installed and used to have better life the only thing I can suggest is recalibrating http://forum.xda-developers.com/showthread.php?t=765656. Sorry if you have already done this before. It's just that when you pull the battery and switch it I'm assuming the battery stats file may not adjust accordingly. It's worth a shot.
I seem to be having the same issues as you. I made a thread over at the Q&A section which may be of some help.
http://forum.xda-developers.com/showthread.php?t=829285
As for losing more than 30%-40% overnight with wifi enabled, there has got to be some lingering issue on your phone if it is losing that much. I don't think any phone, no matter how bad the battery life it has, should lose that much overnight, granted that you don't have a TON of data intensive activities running on your phone.
30-40% WOW!
I get 36-48 hours in between charges on my phone.
Wifi is always on, sync is always on, no live wallpaper, weather and email updates every hour. I'm not on it every minute of every day but enough use for sure.
over night I lose about 5% on average.
Calibrate your battery...but you can't change batteries or you need to calibrate all over again.

As I posted in this thread: http://forum.xda-developers.com/showthread.php?t=829285, I did a factory reset and my phone seemed to be working fine as it slept when the screen was off (checked by using *#*#4696#*#*). It was good until approximately 50% when all of a sudden I checked and it wasn't sleeping once again. Checking the partial wakelock "Android System" was taking up an increasing larger amount of this section. I didn't do anything on my phone as I was sleeping and periodically, when I'd wake up, I'd check on my phone status. When I reboot the phone once this happens, it sleeps once again.
Keep in mind, my phone is stock. Didn't install any apps or anything at all since the factory reset. Now I'm not sure if I have a defective phone. Maybe the Android OS is set up to run like this? There's no such thing as a defective OS is there? Can't be anything on my end because I didn't touch the phone nor did I install any bad apps (or any apps at all for that matter). Can it be a battery issue? I can't see how a bad battery can cause the phone not to sleep. Is there something in the Android OS that turns on automatically after a while that may be causing it?
I'll try to recalibrate my battery but I don't know how that would alter if my phone sleeps or not, but I'm willing to try. I'd rather not take this phone back and get another one as that's a hassle.
Mine will loose 40% over an 8 hour window easy with absolutly 0 use if its near the "edge" of either wifi coverage or data coverage.
IE, sit the phone down with a weak att signal and walk away. It'll die on its own unless you airplane mode it within half a day.
I have to religiously turn the phone on airplane and switch to wireless at home, and turn to airplane and turn wireless off at work (can't connect to work VPN with 2.1 !)
If I leave it on full in either location, it's bloody dead next time I touch it.
However, with good home wifi, I can actually get 4 days of email checking, use as alarm clocks, some other sms stuff without plugging in.
This things is helaciously sensitive to wonky radio connections.
hmmm. I guess I'll try it with wifi on tonight. I don't think recalibrating would cause it to have a 10x difference in idle battery usage, but I'll try that if all else fails
I use Setting Profiles app and have it set wireless to Airplane mode from midnight to 6am. Still, I'm finding my battery down by 30-50% at night.
Looking at Battery Usage, my Display, Cell Standby and Phone Idle we all using the majority of the battery power. I'm not sure if these numbers are reset after the phone comes off the charger or how it is calculated.
I just turned off wifi altogether and have seen huge improvements. I don't even use it anymore despite being in my house with a wireless connection. Data usage isn't that much slower so not much of a loss. At least it can sleep.
i only get like 24 hours on my phone :/

It's not just this phone. My wife's iPhone does the same thing, as did my Q9H. The constant switching from 3G to Edge will kill a battery.

I turned off wifi and have seen an improvement. It's still not where it was before, though - I used to lose 5-10% with wifi on. I wish I knew what happened.
I have been having problems with my battery life pretty much since I have had this phone. I downloaded spare parts app to give me some insight because I have also noticed several times phone seems warm even when screen has been off for some time.
As of right now today, to give an example, my phone has been unplugged for the last 10hours and I only have 44% battery left. Says display is responsible for 71% of battery use yet screen has only been on for 44min of that time (and I have the brightness turned all the way down). According to spare parts "other usage" my "running" time is cause for 35% of batter use at over 3hours.
With these things in consideration I feel that there is something that is stopping the phone from properly sleeping due to the phone being warm at times display has been off for a while and the contrast between screen on and running time. Partial wake usage doesn't show much running under it as most listed items have only a sliver of a bar showing.
Can someone please lend me some guidance on how to further troubleshoot this problem?
i mean that type of battery consumption doesnt seem irregular to me...im at close to 10 hours for the day and have 59% left.
Are you in a shaky signal area? Thats one reason my phone gets warm. especially if its a fringe area where it cant decide between a 3G signal or 4G signal.
In spare parts there is a option for partial wake lock. If something is stuck at 100%, then you know you yuo have a rogue app thats causing your phone not to sleep
But can you confirm it being normal to see 34% time running under other usage settings for spare parts? Partial wake usage as said doesn't show much keeping a wake lock going.
As for signal, not too sure, very rarely if ever see a 3g change over. Is usually at 4g and occassionally hitting edge.
WOW, you get that good of battery out of yours? that seems epic haha, i get 3-4 hours tops.. i mean i abuse it, but still..
I charge mine at night. Ran it from 7am to 12am and it was at 34%.
Yeah see...7am to 12am and 34% remaining? No way I get that.
If it werent for the results I'm posting regarding "running" percentage from spare parts other usage and the screen on time I would just accept it as a phone deemed to have bad battery life, but it seems to me like something is going on and I guess I'm looking for someone to confirm or dismiss my suspicions.
Maybe I'm also a little spoiled coming off my G2 that was rooted running CM Rom and CPU ramping/cut down which in combination gave me, under the same amount of use, a situation where I was getting home at night and still having 40-50% battery left in comparison to the 15% I commonly see now.

once some custom kernels come out that let you uv/uc/oc then i would say you can expect the same type of results..i just went on a trip with a friend who has a g2 and he was constantly crying about his battery dying, (stock), where as I only had to charge mine on average 1.5 times a day with moderate to heavy usage. I find this battery phenomenal compared to all the other android devices ive owned and tested
damn!
i charge mine every other day.. hehehe i dont abuse it or anything though.. just regular internet every few minutes or so.. i have the BETA juicedefender installed guess that helps a lot. data is off when the screen is off, set it to agressive..
here is the app hope it helps...
I noticed the same problem,i brought this phone on saturday and was very impressed with the battery until yesterday night I noticed the same thing, my phone was at 50% and I had it sleeping then I get the battery low notification 10 minutes later and the back of the phone was real hot. This can't be normal cuz I have the same apps installed from 2 days ago and I was using the phone heavily even using mobile ap and still didn't have this problem, if you guys find a solution please share it with me.
We need to be precise in what we communicate in order not to have misunderstandings. Many threads disagree on how good the battery is on th G2x. I agree that 6-8 hours of continuous use is great, that is if you're literally using nonstop, without having the screen shut off.The problem that many users are complaining about is that the battery keeps draining at a unacceptable rate even when the phone is just on standby. The excuse is that this is a smart phone and it has to ping the towers in order to receive calls.
Well my last smart phone was the HTC Shadow which was a Windows based operating system and the battery would never drain at 5-15% an hour just on standby. I did some reading on many sites, and the majority consensus is only android handsets have this huge battery drain problem when it's not being used but just on standby. So what gives? Is it because of google maps? Or some other google program that has to constantly access your phone even when you yourself aren't activley using it?
I've notice on my juice defender log that when I'm not using my phone it shows every few minutes something about accessing a schedule and data. What could this be? Back ground data? The only way I can get the phone not to drain excessivley when on standby is to put it on airplane mode. The bad battery drain when phone isn't being used has something to do with the Android operating system and the cellphones radio being very active even when not in use.
Factory Reset fixes that

Believe me I tried resetting it twice, and it does nothing for improving the battery drain.
If any one has juice defender go to status tab and check your log. Even with the supposedly data turned off it'll show the the phone us accessing some schedule or data every few minutes.Maybe one of the knowledgeable developers can look into this and tell us what is happening and create a fix.
You may have a bad battery.
The battery that came with my G2x in the box (manuf. date of 2011-04-06) had the insane battery drain where I can watch it drop. I got a replacement thru Tmo (manuf. date of 2011-04-28), which has been outstanding.
Prior to the new battery, I lasted about 7 hours with moderate/heavy use. The new battery just clocked in at almost 16 hours the other day.

We'll see, I just spoke to t mobile customer rep, they shipped me out a new one which should get here on the 3rd. Although, I didn't appreciate them charging me $10 for shipping. 16 hours of heavy use and I'll be content, if not I'm getting me the mugen 4500mah extended battery. So with o out you touching the phone how much percent does it drain in an hour?

Right now I'm at 99%, phone has been unplugged for 2hrs 34mins. I'm on wifi at the moment, but I would have drained anyway on the old battery with this same setup.

Yup, same exact setup with old and new battery.
I'll try when I have the time and patience for it, but maybe someone can perform an experiment by charging to full then just let the phone sit on standby until the battery dies. Do this with wifi, bluetooth, juice defender and gps off. Log how long it took to die, then run the same test again, but with juice defender turned on. If it can hold it's charge for 2-3 days I'll be very happy, but if it dies out in 16 hours just being idle and on standby then somethings wrong.

JD only kicks in when I'm on cell data. With wifi on, it never activates I believe. Unless I'm looking at this wrong.
I was getting horrible battery life when I first got mine. I couldn't go 8 hours without it dying, and that was not even using the phone...on standby! I tried a toggle switch for data to turn it off and on when using it, but it still died. Next, I tried a 2g-4g toggle switch. Battery life is flat out amazing now. I can go almost 8 hours on a full charge and be on maybe 95%!!! I think a lot of it has to do with my office building and not getting the best reception. I would tend to bounce back and forth from edge to 4g all the time. Anyway, I use switch pro for the toggle widget, but give it a shot for a few days.
Switchpro only has a 2G/3G toggle. How did you get the 4G toggle or did you mistake what it was called.

I had a similar problem with my first G2x. With the screen turned off and in stand-by the battery would drain 15-20% per hour. I even bought 3 cheap batteries from China and the results were the same. I then had T-Mobile send me a replacement G2x. The new G2x drains about 1% per hour in stand-by. I even get 1% drain with the 3 cheap batteries. So it appears the problem was the phone. I had tried CM7 and Eaglesblood on the first G2x and it didn't stop the drain.
I had terrible life when first started, than I did the factory reset and the battery conditioning thing.
Took it off charge over 30 hours ago, it still has 10% left. Within that it had a solid 2 hours use of edge/3g/4g internet (Searching for towers as I was on a train). And a good hour of me using it on wireless for checking emails and browsing while at home and work.
Note that I have GPS turned off, and the phone is on a wireless network for almost all of its idle time. NO Juice Defender, no data stwitching, no rooting. Stock standard, although I did follow the advice here and not activate any of the TMobile apps.
Pretty happy with it now.
Anyone know where to get an extended battery? Thanks.
I can't even find a place to buy a regular battery for the phone. I'm not sure if I would need one, but it would be nice to have. I'm in the habit of charging it the last hour I am at work so no matter what, I'll never run out of battery even if I go somewhere straight from work, but a spare battery is always a good thing to have.
I have a wild guess as to why not.
I noticed this phone battery has the "near field communication" labeling on the BATTERY. The other phone that I'm aware of having NFC, (the galaxy s2) does NOT have this wording on the battery.
Why did I notice this? I randomly read that there is an SD card manufacturer that is putting NFC chip's into their microSD cards, and even some ipod cases are getting NFC chips built into them as well.
I don't know too much about NFC, but with the labeling being on our battery, and not the S2, I kinda think our NFC chip is actually in the battery, and not the phone itself. If an NFC chip can be put into an SD card or case on a phone that never had NFC to begin with, I don't see why it couldn't be put into a battery, especially since one of the terminals might not even be for power, but just for an NFC connection.
That's my theory, I could be wrong!
you're probably right. This is how it is with the Galaxy Nexus, also built by Samsung. I hadn't noticed the label, but I also wasn't looking for it.
I'd be curious to find out what an "extended battery" for this phone would look like. I'd be all for it so long as it kept NFC and didn't bulge out of the back
I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery
I'd bet you a waffle cone your screen brightness is set too high.
Forget most of those "battery defender" apps, especially if they are those stupid task killing applications.....a program being in active memory is not necessarily actually doing anything, which means it is not using your battery, and if it gets killed, if the OS needs it open for any reason, it having to be re-opened will just use cpu cycles anyway
I'd agree with most people that using the automatic brightness option is very annoying, it's really sensitive and it also tends to make the screen not be bright enough. Having said that, using any of the many available brightness widgets can be a very good thing.
The stock one is not so bad, personally I've been enjoying powerful control, http://goo.gl/2vZXl but I've had great battery life and easy readability if I use the brightness setting where it looks like a half moon.
If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

My screen brightness is at zero without automatic brightness on, and im not using haptic feedback. The phone battery is fine if its just sitting over night, but as soon as I turn on GPS to use maps for 5 mins or to check facebook the battery just drops a % every min. So i guess the phone is fine if Im not using it, but then whats the point?
You're exaggerating.
I've never had a phone battery drop 1% per minute.
Look man, I just spent 5 minutes playing music at max volume, while getting directions to 8 different places in google maps, sent two emails, downloaded a new app from the market, and received one text message.
Battery level after all this? Still at 100%. Does that mean I can do this an unlimited number of times? No, it does not.
Frankly, I don't believe you. I've used this phone, and my previous phone for playing movies at full screen brightness with the audio being played through bluetooth to my stereo headsets. Does it effect the battery status? You bet it does.
Two weeks ago when I last played a snes game on my phone I did so at full screen brightness over bluetooth to a ps3 controller. When I wasn't playing the game I was sending or receiving text messages and had vibrate on. I played super metroid from the very beginning to almost through the end of the game. When I play snes games on my phone I tend to use quick save and quick load and frame skipping very commonly, effectively letting me do things "perfectly" but this is a lot of saving and loading and running the game even faster than how it normally is. I started at 2, and the next thing I knew it was 6:00 and I was supposed to meet a friend for dinner at 6:30.
But for crying out loud you are saying you can drain your battery from 100% to zero in less than 2 hours.
I'm calling shenanigans. I don't think you could even do that intentionally, unless you sat there and forced the phone to vibrate the entire time.
Phone batteries don't last for days like they used to. Batteries have not changed too much in the last few years, but the things phones do, and the screens they do them on certainly has. Stop expecting your phone to last over the entire weekend even when you actually use it.

I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery

Something to keep in mind:
When this phone hits 100%, it STOPS CHARGING. Even plugged in, it will no longer be drawing power into your battery, yet it'll still be running on battery.
If you plug it in when you go to sleep, it finishes charging within 2 hours, then it goes 6 hours idling on battery power but it still says 100% until you disconnect it. Then, while you're using the phone it'll adjust as you use it until it gets to the right level. This is likely what you're seeing.
If I use my phone from the moment it finishes upping to 100%, I get great battery life. I get great battery life in general and have been happy with the phone.
Of course, this might be a totally different issue where you just got a bum battery. But it's something worth considering.

I don't believe this is true. I hate to constantly be a naysayer in this thread, but this didn't seem logical to me so when my battery went to full, (when the battery is full, unplug charger text showed in the notification bar) I kept it plugged in and set it to play a couple tv episodes on full brightness while I did laundry and made dinner.
Two hours later, I first looked at the battery status while the phone was still plugged in. As expected, it was at 100%.
I unplugged the charger, waited a couple minutes, and checked again.
Still at 100%, which completely makes sense because I've never had a phone that behaved as you've described.
I also would have noticed the battery dying very early, *every single day* because my habit for the last week or so has been to plug the phone in when I go to sleep. I have an app called syncme that pulls files off my computer such as music and video while I'm sleeping, and on average it transfers about 6 gigs of data this way, every single day.
I don't know if you've ever transferred 6 gigs of data on a phone via wifi, but yes, it's not exactly battery power friendly.
My phone's always been 100% battery when I leave for work, just like my last phone was where I also plugged it in at night.
Just saying!
So you guys know.. I have galaxy nexus and the blaze and the batteries are the same so you can order a battery fro the nexus and it will work with the blaze

Just did an ebay search for Galaxy nexus.. You might need to clarify which model number as there are various Galaxy Nexus batteries listed per Nexus model on ebay...
Galaxy Nexus GSM I9250

Actually he is pretty close to the way it operates. The way your phone gauges battery life is similar to your car with gas. When the meter reads 100%, it is really more like 98%. When the battery reaches true 100%, the phone will stop charging the battery (but will run off of USB power, not the battery). They do this to account for small variations in the many variables that affect a battery's performance (like temperature). Likewise, your phone will read 0% before the battery is truly completely drained (this is also to protect the battery - they don't like being charged to 100%, nor drained to 0%).
This could also greatly affect your previous test on battery performance. To get a more accurate result, let the phone drain to about 60%, then test the time to drop a percentage point.
What you are talking about is a suggestion that the battery meter doesn't necessarily update it's strength meter all of the time, and you even say that the phone runs off the plugged in power at this point.....

His entire post is incorrect, and has nothing to do with what you are talking about either.

Before you discredit anyones post, you should understand how many battery chargers work, and the importance of them shutting off following a complete charge. Here is a quote regarding Li-ion battery maintenance :
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Many chargers have this feature built in to avoid any overheating and/or damage to the cell. I'm not saying this is the case because I have not tested whether the battery charging circuit in this particular phone, or it's charger operate, but I will say that this has been the case in MANY of it predecessors.
That being said, I think an extended battery would be a welcome addition to the options of this phone. Mine too only lasts a day at it's best. Perhaps not 1% a minute...but then again who knows?
