I noticed a small current leakage when charging my Sensation with a 1730mAh battery, and some strange effects if I handled the phone for extended periods while charging - like the power menu popping up when I hadn't pressed the power button.
It only happens when charging on mains (direct AC), not when charging on the PC, probably due to the increased amperage.
The battery is about 1mm thicker, and I suspected it was somehow causing something to make contact with the case. I could feel the leaking current by lightly rubbing the metal case with my finger and feeling a sort of 'fuzziness'. This only happened when it was charging, and I was able to reproduce this problem with both the HTC OEM Evo 3D 1730mAh battery and the 3rd party Anker / Chichitec battery (all about 1mm thicker than the stock 1520mAh battery).
After reading this thread, it dawned on me that the slightly thicker battery was probably separating the contact between the case and the grounding pin. The battery fits perfectly and snugly into the Sensation, but the increased thickness was just enough to reduce the case's contact with the grounding pin.
I was very careful to bend the grounding pin out slightly with a tiny screwdriver as described/pictured in the first post of the thread.
Now there's no more current leakage!
Have been using an Anker for about 3 weeks now and have not noticed any type of issue like this.
Thanks for the info though I'll take a look into it.

The issue only arose for me when charging on mains, and I held the phone in my hand and was using it for extended periods. If the phone wasn't plugged-in to the charger, I never had any problem.
You can detect if there is a potential for the problem by checking for the current leakage while it's charging, as I describe above. While charging your phone, place it on the desk and lightly rub your finger along the top of the metal case... If you feel a sort of 'fuzziness' (which disappears when you unplug your phone), then you have current leakage and might want to consider checking the solution I link to above.

Did you try with the stock battery if there is any "fuziness" feeling?
I'm using stock battery and had fuzziness feeling when charging through wall. But its not a big deal for me anyway.

The stock 1520mAh battery didn't have the fuziness feeling, because the grounding pin was making contact. The slightly thicker 1730mAh batteries (about 1mm thicker) separated the contact.
That said, some people experienced screen issues with the stock battery, because the grounding pin wasn't making contact even with the stock 1520mAh battery.
Most people don't have the problem with the regular battery, but I expect more people will experience the problem with the slightly thicker batteries.
Either way, same fix.
I get this fuzziness on my phone with the stock battery!
I'd been wondering what was causing this for the past few weeks.
Thanks for the tip about the grounding pin, I'd seen it but hadn't made the connection.
I wasn't too worried about it because my Hero also had the same feeling around its metal screen border when charging. Is it bad for the phone?

The fuzziness means your phone's case is not grounding properly. You may not have a problem now, but it can cause touchscreen issues (including slow degradation of response). It especially arises if you use your phone while charging (so you ground the case to the screen with your hand).
Anyway, the fix is easy, but it's up to you.
Crazy. Thanks for sharing (rushes off to check my sensation)
I used a knife to do this
I didn't have any problems but I am using anker 1900mah
so I feel best to be safe, ground problems can be dangerous
hope this helps
Yeah i get it too with the stock battery too. What every happened to quaility control with products these days?
This is because of improper EARTHING of electic connection/supply at your place.
I face this problem too sometimes, no matter which battery i use. You can feel a slight electric current on the centre back portion only because that is metal....

It will probably fit, I don't doubt it but there seem to be a battery door as well and by the looks of it. Although it seems its for the fasinate only.
the fascinates battery fits but when ever I charge the phone, it says battery not detected, and the phone does not charge. more than likely you'd get the same error with the extended one.

I bet the batteries are fine, it's getting the door to fit back on being the next issue.
i ordered me one
now waiting for epic battery cover
Since the battery is thicker, you could halfass the cover by simply cutting an opening in it just enough that the battery could protrude from it and still allow the stock cover to snap on. Other than it being pretty, the battery hump would stick out less than the cover that is included on that eBay Fascinate link. Or maybe you could get really fancy by cutting off the bump from the Fascinate cover and epoxy it or something to your existing Epic cover.
As I'm sitting here writing this, I'm thinking about just doing it myself...dremel out the hump and epoxy it to the Epic cover, using enough epoxy to create a smooth transition lip instead of an actual bump, light sanding to clean up the epoxy work and then wrap it in some 3M Di-NOC carbon fiber graphics while I'm at it.
The ONLY problems I've ever heard with some of the aftermarket batteries (while I was on the Samsung Moment forums) was that occasionally people would get an incompatible battery warning on their phone, but could easily be resolved with a reset. Once you get yours, keep us posted how it works out. When I first got my phone, the battery was completely dead, but I was thankful. I read random stories (which are debatable) as to if battery conditioning is even necessary or if it even matters. Either way, I put my phone on the wall charger (faster than USB via a computer) and let it charge completely. I then ran about 4 streaming music apps at once to completely kill the battery, then did a nice slow charge on the PC. While I can't say if my battery life is good or bad compared to anyone else since everyones usage is different, at least I can say I tried to condition it. My point is that I've tested the life of batteries this way when swapping between older and newer batteries on my Treo as well. Charge them till their full, run a battery intensive app (streaming for example) and timed how long it took to die. I have Treo batteries that lasted as little as 1.75hrs and as much as 3.5hrs, so naturally I keep the 3.5 in there as much as possible. You could test your current battery vs the extended battery the same way. I chose streaming as my testing of choice since I stream music while working anyways, so it wasn't anything out of the ordinary...I'd just let it go until the music stopped, noted the time and swapped to the next battery. Maybe you could do the same to confirm the difference in life between the 1500 and 2200 battery, otherwise we'll never know.
On a side note, I like this cover http://cgi.ebay.com/3000mAh-Extende...788955?pt=PDA_Accessories&hash=item5adbfc1b1b since it thickens the whole phone vs just adding a hump. That hump would just be constanly snagging the edge of my pocket everytime, hence why I wanted to make it a smooth transitional edge like I mentioned above. Also, this battery is 3000mah, 2x the stock Epic battery. Is the i9000 the same height and width as our batteries? It'd be an even larger hump, but twice the battery...hmmmm.
One thing to keep in mind about battery ratings is that it is dependent on discharge rate. A battery discharged at 1 c will have a different and lower apparent capacity than the same battery discharged at 0.1 c. Thus a larger battery benefits in two ways. Physical size and lowering of the c rate based on the same amp draw. This is where less reputable battery makers cheat. They will put an incredibly small load on a battery to achieve a higher rating.

So, what's your point? How does one distinguish a good battery vs a bad battery then if we're going to try and test these?
I'm waiting for Seidio to release this battery. They have an extended battery for the Evo and it gets good reviews overall, as seen here. Super expensive and makes the phone super bulky though
Why wait for Seidio and their overpriced batteries? People have been buying the extended batteries for the Moment for years via eBay, so why would any of the Galaxy S line batteries be any different for the sub $20 range?

The point is that unless they are giving you a physically larger battery, not to put too much faith in the MaH ratings of batteries. Especially ones out of china with no brand to speak of. The difference between a 1500mah and a 1700mah is likely in how they discharged to to rate it.
If you can find it, the C rate on discharge is a good indicator of quality in lithium batteries. Higher C rate discharge have lower internal resistance and are made with better materials. I'm not sure how likely you are to find the full specs on a phone battery.
In a test environment its not too difficult to figure out which is which. Put a temperature probe on it, and then put a high load on it. The one with the lowest temp is probably your best battery. (same size anyways)
Assuming the 2200mAH batteries are genuine Samsung OEM, I'd love to see one get tested by the guy at batteryboss.org to see how they rate under the same test conditions as the other batteries he's tested. If they end up being real, honest-to-god 2200mAH @ 250mA discharge, that would put them right on par capacity-wise with the average, much thicker no-name nominally-3500mAH Evo/Desire/Hero batteries from eBay. 1500 definitely isn't big enough, but a real 2200mAH battery with back that's large enough to accommodate it (preferably with a sculpted, rounded profile instead of a boxy pregnant lump) might be a nice alternative to a full-blown ~2800mAH-nominally-3200/3500mAH extended battery from Seidio.
In any case, I think it's been well established by now that the "extended" batteries that are the same size, but ~100mAH larger than stock, are almost a complete waste of money. Even when they DO last 30-60 minutes longer, you seriously have to question the sanity of spending so much for so little.
That said, I suspect that most of the cheap 2200mAH batteries that will eventually end up on eBay will end up testing out at around 1500mAH.

I think I got what you mean. Either way, both the 2200mah and 3000mah battery are incrementally large than the next vs the stock 1500mah battery, so I would assume that each battery will in fact store more of a charge.
has anyone tested whether these batteries work and charge normally? If they do work, you can grab a cheap hard case on ebay for 3 dollars and cut a hole through it for the battery. It will be ugly though, unless you figure out how to make it look nice

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.

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.

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.

I have a sensation but this could work with all phones if it is not just a coincidence. The battery life on my sensation was terrible and I thought it was because of the cheap eBay battery that it came with from Craigslist. I noticed the battery was loose in the frame of the phone, so I tore off a piece of a business card that would fit on the opposite side of the contacts, that was small enough to be flush so that the back cover would still fit properly. This tightened up the battery in the frame. Since i did this my battery has lasted much longer, and I no longer get random reboots. Possibly there is less resistance now that it is pressed up tighter to the contacts, or it could be a coincidence and this would be a pointless post. If your battery is loose in the frame, give it a try and see if it makes a difference.
Tôi có một cảm giác . very gooo...
i believe it is a coincidence, better contact doesn't exactly translate in to lower resistance. the phone battery is very low voltage, the itsy bitsy little connectors probably do more than an excellent job of transferring the charge. If you think about it having a better connection would drain it quicker, a bottle drains faster if you have the top taken off, but slower if you just have a tiny hole poked in it.
i could be completely wrong and i have a different phone this could completely work for your sensation

I would say next to impossible - even if you did crack the back open and "replace" the battery with a bigger one (feasible), you would have to put a bigger cover on it - as I assume you want to put in a larger battery?
I think they make one of those cases that has a battery in it for the Q... Other than that, I would say carry around one of those emergency recharger thingys.
Battery can be replaced easily, it just needs a T5 screwdriver and something thin and plastic to remove the back cover (of course, you don't crack it), if you want just to replace it with another stock one.

You can't just put two batteries in parallel without additional circuits to prevent one sending current to another (which will happen whenever their voltages are not equal and is like shorting the battery (see Kirchoff's laws), because the internal resistance of the battery is low when charged). And then you have to secure the same thing for charging.
Also other issues like not knowing the current state of the both of the batteries etc.
I someone would be to "mod" the cover, I'd suggest checking out on RAZR MAXX 3300 mAh battery (the phone is 4.3"). Can't find the size of RAZR MAXX EB40 battery anywhere
Also looks like somebody did that for Atrix HD (http://www.youtube.com/watch?v=0jql0jxpBpA), but that is using EB20 battery like the original RAZR, we have a different one (strangely, named EB41).

The NFC antenna comes off pretty easily.
Will it be possible to mod by screwing the 2 metal pins down to the position where EB41 was originally connected, then housing the similar looking but ordinary after-the-market batteries not EB**?
Then, we can easily replace batteries on the go.
AW: How integrated is the battery?
I have to say till now I am comfortable with the built in battery. It lasts a normal workday, so no problems.
But as always bigger battery would be better. Personally I wouldn't put another back on to increase battery lifetime, but exchanging the original one with a stronger one (maybe with some small 'mods' inside the original housing) is a way I would consider.
So if anyone has news on increasing lifetime without to strong mods I would appreciate suggestions.

96 x 56.5 x 2.5 mm and the MAXX battery (3300 mAh) is just thicker. Unfortunately, Photon Q battery is sized cca. 71 x 46.5 x 3.0 mm (measured roughly, didn't find it on the net). That's 1 cm overlap on side and 1.5 cm overlap on lenght, won't fit there, unlike on the Atrix HD
rats
that echoes my research
Would it be possible do modify the Photon Q's battery at all? Like replace it with a RAZR MAXX HD's battery? I can't find dimensions on either battery or anything like that.
I was also wondering if it'd be possible to maybe take apart a battery (perhaps two Photon Q batteries) and somehow put them all in sequence and have it work like that. I'm a noob when it comes to these types of things. Any help is greatly appreciated!
You would have to get the measurements of both batteries and compare the sizes to see if the RAZR batt will fit. It looks to be the same voltage and chemistry.
You cant use multiple cells without special circuitry for charging. The best option is to find a larger cell of the same chemistry and voltage then mod the phone to hold it. Also, you would probably have to sacrifice a working battery to get the connector.
I added a larger cell to my Motorola Triumph

It's not easy to get that info, but looks like the RAZR battery, altough surely electrically compatible is not the same size.
Razer's one is 1.5 cm longer, and is also narrower.

Well, surely you can't put two "smart" batteries in parallel from the outside, but it's feasible opening the battery and connecting properly the cells, internally.
But this must be done by someone who really knows what should be done, to avoid risky situations.
You can connect multiple cells in parallel but it's not a good idea without a proper circuit to charge the cells. Over time the cells will need charged at different rates.

On small batteries like the one you can find on a cellphone "Proper circuit" could be just a couple of resistors to balance the "neighbor" cells.
I'ts way different on bigger batteries, like notebooks' or electric cars' ones.
Given the increased energy stored (and the increased risk) in the latter cases the charging circuitry checks every single cell, not the whole battery as happens on cellphones.
So doubling the capacity of such batteries is a completely different matter, a complete redesign of the charging circuitry (and battery firmware) is needed.
Alright, so I'm pretty sure I've this all figured out except for one thing. What the crap is this green..... thing on the back of the battery? It's like superglued onto it and I'm thinking it's an antenna of some kind, perhaps for NFC.
BUT, I can basically just connect the RAZR Maxx battery like this to mah phone I'm thinking. (see image)

EB40 (Razr Maxx) and EB41 (Photon Q/Droid 4) batteries have completely different dimensions.

Yeah, I know this. I'll just wire it like in my image similar to what the other dude in this thread did with his Triumph.
This is why I wish Samsung would've made an S3 slider.

Wiring a different battery is definitely possible.
I did it on a HD2 clone, using a Mugen battery meant for the Palm PRE.
The hardest part is to find a battery with the correct dimensions, usually find the right one is just matter of luck, given is hard to know the exact dimensions of a battery before buying it.
There's finally an extended battery (3800mAh) available for Droid 4.
(Droid 4 comes with the same EB41 battery as Photon Q).
So there's a battery that should fit (apart from its thickness, obviously).
The main issue is that there's no back cover for Photon Q to fit this battery.

We need 3d printer for back covers!
Or just wait a few month, I think that the back cover will come for the XT897.

The main issua, as usual for the mugen batteries, is the price.
89$ is more than what I paid the whole Photon Q.
Or, if you prefer, is 15x the price of the original extended motorola battery I'm using on the Phonton 4G
i just wrote to mugen power an email and asked if there is the possibility for a extended battery, as the droid 4 battery fits in the photon and only a bigger backcover is needed. this is what they replayed to me:
Thank you for your email!
I will pass it to our technology and marketing group to see will them make the cover for photon Q.
Will let you know later!
Please contact me if you need any additional info.
Best Regards,
Jan

Just got a Photon Q so I would certainly love if they made a back cover but am doubting they will. Thought of just buying a second cover on ebay and cutting it / using some epoxy to make my own with the Droid 4 battery.
Dual Battery Photon Q
I know, seems insane but I've been running my phone like this for the past year and have even made a second one which is also running fine. Reason why I did this was because I'd bought a Photon Q in the summer of 2014 (previously with Verizon). The phone was brand new but the battery has been on the shelf so long that it was crap by the time it got to me. So I went and bought a replacement batter on Amazon. It already being a two year old phone, the replacement batteries went for only about $8. So I bought two. Upon receipt, I inspected it an thought of possibly soldering the two together to see what would happen.
Initially, I soldered the primary contacts of both batteries to each other (including the PCB), which didn't work. On my second attempt, I disassembled the housing for the PCB and soldered just the leads of the cells together and kept the PCB of one of the batteries. It powered on and worked properly. In fact, with two batteries, it seemed as so the phone worked faster than it did prior. I'm assuming more stable voltage.
Anywho, if anyone wants a 16 hour Photon Q, this mod works. The only thing that's off though is the battery meter. Since I don't know how to reprogram the PCB, the phone will hit 3% battery life after eight hours of use but will continue on for another eight hours. I've been using my phone like this for about a year now and it also seemed to have learned the new battery life. In recent days, the phone would actually shut off soon after the 3% warning. The second phone came into play because the touch screen stopped working. I tried to fix it but ended up breaking my phone instead.
I know I know. I'm crazy for allowing a lithium cell to be that closely exposed to the atmosphere. Whatevers, yolo. Anyways, the antenna is sandwiched between the two cells, back cover chopped up with a razor, and if you're fans of the car dock, you can take off the top layer, chop off what you need to accomodate the battery, and glue the remainder of the top layer back to the base. Like a glove!
