QCell AT&T Samsung Galaxy S2 / SII SGH-i777 3600mAh Extended Battery - AT&T Samsung Galaxy S II SGH-I777

Hello guys,
I purchased one of these and so far so good. I'm running an AT&T Samsung Galaxy S II- with "ICScrewD Red Edition UCKH7" Rom
The battery is able to charge while the device is operational without boot loops.
After the first charge I ran cpu/memory/gpu stress tests serveral times during the day, kept BT, WI-FI and GPS on while on the road, streamed music, watch videos, set display to max and time out to 2 minutes to expedite discharge basically above normal use.. The baterry lasted 20 hours under those conditions.
After a second full charge the cellphone have been running on battery for 28 hours with almost 4 hours of display time and is showing 56% battery charge left.
The back cover fits perfectly. The only thing I would like to find is a travel charger for it. I bought a GTMAX charger but the battery does not fit in it. I can only charge regular size batteries on the travel charger.
Hope this helps others looking for an extended battery.

3600mah?! that's intense. Would you mind posting up a few picks to compare the thickness of the phone with that on vs Stock? Thanks

No problem. Will do once at home a little later.

Don't know if I want to trust another battery from Qcell as far as what capacity they rate it.
Bought a supposed 1950 mah battery through them and it turns out that it's really only 1650 mah. While the battery performance is on par with stock which is fine, if you buy it under the pretense that it'll get you better battery life, stay away.

Cool, can't wait to see your results.

Do you have any pictures of it on the phone? Is it awkward out does it work well?

I decided to give this battery a try because of jury duty coming up. I'll drain it then charge it over night and should have some results soon. Pictures on the phone are included for those that want to know how it looks on the phone.

When I look at those pictures, all I see is this
Are you going to get some sort of bumper or case to go along with that? I'm interested to see if the battery door/cover from other 3000+mAh batteries would work with this one - like the one from the GT Max.

I'm going to use the SGP Neo Ex with the battery. I tried the tpu case for extended battery packs but it didn't fit. The back cover of the gtmax didn't fit my phone correctly.

LMAO, yeah I'm not big on the design of the back cover but it's going to get me through hours in the jury pool. I have a seidio on order and hopefully that back cover will fit better than the first one I ordered.

nice bat. What about the first uses? should you discharged full and then charged till 100%? or you should use it normally till like 40% and then recharged full? (40% to don't degrade the battery life)

3500mah battery woes....

So here's the deal. I bought two 3500mah batteries for $24 bucks off ebays "buy it now". They're cheap chinese 1billion made type batteries but last 36 hours. 17 avg off my 1930mah stock so worth the $25 in my eyes.
Here's my issue. I've installed cm7 beta with new battery in at %100. I've wiped stats at %100. Let it die and recharge without interruption. Wiped battery stats numerous times. Cmw and the calibration application. My issue persists. I will have the same "stats" as my stock battery but with a huge "reserve". By reserve I mean I will be at %1 for 7 hours or more. I can't be the only one.

I'm having similar issue with a "2000mah" battery off ebay. Lasts aboue twice as much at 1% vs. 100% to 2%. I've noticed that battery is around 3900-3800mV when it first reaches 1%. and phones shuts off around 3400mV...

interesting, will try that.
the odd thing is that the original battery goes dead at 3400mV also...
I wonder how these things work. Does the phone "remember" different batteries, or is it just the same "calibration file" for any battery plugged in? if that's the case, then we cannot use "spare" batteries then?

All modern lith ion batteries max out around 4200mv (anymore and they risk exploding) and are considered "empty" at 3400-3300 depending on the manufacture, if they decharge anymore they won't charge again. I'm guessing there's a calibration chip in the battery that's messed up on the Ebay batteries or something of that sort. If you were to but an OEM battery the battery life gauge works just fine.
Think of it like this mV is how full you're gas tank is in you're car 4200 full 3400 empty. Now every car can be 100% full but every car doesn't have the same size tank or Mah in this case. So basically you switched the gas tank on your car with a bigger one but didn't change how it reads how full your tank is so basically you need to guess by your mV.

i just ordered one off ebay for 10.50, its on its way i will let you know how mine goes

No idea if this battery will work, but it was cheap

I'll let you guys know how it works, hope it doesn't mess anything up. Less than $8 shipped. If it doesn't work, it was worth the $8 to find out.

Is there a cheap dock anywhere? I mean like $5, I'd love to be able to use this battery but geeze, this should just work.
Wouldn't this work?

yes as long as the battery is the same size as the original it would work. I noticed with the 3500 mah batteries the charging spot wont fit, but that should be fine
Battery is awesome. Been in since 8am and it's right under 50%(I'm a heavy user). I'm going to test this battery back to back with the stock one and show results maybe Monday. Got the charger for the battery, works fine for me.

That's how it works (and has been stated no less than 200 times in the 30 or so threads addressing the issue. You either buy original, or have to charge externally. For me, having to use a dock-charger is utter BS. I don't have the time nor desire to remove the battery from the phone to let it recharge. Carrying multiple batteries is just silly. If you're going to go through that hassle to save a couple bucks cool, or you could just carry a second OEM battery. Guess some people put a different value on things tho.
These looks like the same ones I got from amazon a while ago ($16 for 3 batteries + charger), you can see my complaint here
http://forum.xda-developers.com/showthread.php?t=1298380
The batteries are cheap and very generic, I junked one 2 days afterwards as that one with it charged to 100%, it lasted maybe 6 hours. It also charges in like an hour. The other 2 batteries, i would say that it last about 60% of the OEM, getting about 20 hours from them with about 1.5 hours of screen time. Still, its usable, but I did not find them to be as strong as the OEMs.
I hope you have better luck with yours...

Using T-Bolt batteries in your new Rezound

Yes, the T-Bolt batteries will fit. Standard size batteries will NOT charge in your Rezound. Extended batteries will fit the Rezound extended battery cover, and WILL charge in your Rezound.
VZW is still selling (I think) a standalone battery charger for $5, so if you have a bunch of T-Bolt batteries and want to use them, that is a simple way to keep them charged.
I'm not seeing good battery life at all out of my T-Bolt batteries. Yes, I realize they have a smaller capacity than the Rezound, but I'm only getting about 2 hours of use before the T-Bolt batteries die. Still, they make good backups.
seriously, i don't see how you tolerate doing the whole battery swap bit. granted i used to do that for awhile with my Thunderbolt, but once i upgraded to that 4500mAh battery i swore i'd never do the swap bit again.
right now i'm considering getting that 2750mAh Rezound battery, but $60 is a tad high... i hope something else comes out soon.
I hate swapping out. I'm getting a solid day out of the T-Bolt extended batteries. But, I hate being without extras, so it's nice to throw a couple of batteries in the glovebox, bag, pocket, etc.
Swapping is far better than having a giant ugly phone that doesn't fit in your pocket and still have to have tethered to a charger for hours at a time. 2 extra batteries and a standalone charger and you never have to charge your phone, you never have to worry about how much battery you have, just let it die and swap it out. Extended batteries dont last all day either with heavy use but two standard batteries will and you always have a 3rd battery waiting when you get home if you go nuts and god forbid watch two full length movies.

Hyperion 5200mah battery for 19.99 anyone have?

Soi saw the hyperion 5200mah with back cover on amazon for $19.99. Anyone have this battery and if so is it actually a huge step up in terms of battery life? Its double the stock battery but we all know what that can mean though so is it an actual good increase or no?

I have an Anker 5200 that I got off of Amazon, came with back cover as well. Cost me the same $20. And mine made a huge difference... Definitely twice the battery life for sure and the 5200's are nice because there not too too big.
I'd imagine the Hyperion would bring the same results.

Oh Yea! It gets me through the day... right now I have 60% Battery left with 8 total hours on the battery and 4 hours screen on time.
And usually it's better than that... Just today I spent some time in recovery and flashed a few things so these stats are not even the best.
With my use I can get like 10-12 hours screen on time. This on an AOSP ROM running a custom kernel + Greenify.
It's definitely the perfect battery for me. Only like 2 times since I've had this battery ( about 7 months ) have I had to charge the phone during the day. And that was only cuz i used Navi + Listened to music + Some other apps all day non stop.

Wonder how much different the Hyperion would be to the anker. I remember seeing the banker on sell but didn't recognize the name so didn't jump on it.

You know I don't know how much different the two batteries would be. Both are very good companies and from what I've read both had very good reviews. So you probably can't go wrong either way.
I have Hyperion battery in my girls S4 and that one seems to hold up pretty well. It's not a big one however so I can't compare...

Just an FYI.* I finally got the battery, touch slow for postage. Took about 3 weeks.
Anyway build quality on first impressions seems good, nice finish.*
Doesn’t have a strong click but nevertheless does connect the phone nice and secure.
I got the cover without a front flip section.
I used to have a galaxy so this phone is heavier by comparison but I’m used to the extra weight now however have to admit, this does make it a fair bit heavier.
Button on the case for charging is easy to use.
My drawback is the website clearly says data support is available but when I checked with the seller, they confirmed this isn’t the case and will be amending the website shortly.
If you can get passed the weight issue and increased bulkiness its overall pretty good just without data sync

@Haldi4803
I have tested the battery, over all I concur that it is built well for the price (I got it for ~$20). However there are a few issues:
- The real battery capacity is approximately 75-80% of the Z2's battery. It charges the Z2 to about 80% total from full to empty so the capacity is more like 2600 mAh.
- The input and output currents are lower than what the Z2 can charge. It can charge at 0.8A and discharge at 1A which is not terrible but does take significantly more time (50% longer) compared to charging the Z2 normally.
I'm happy with the purchase due to the convenience of being able to charge the phone untethered whenever I want to prolong the built-in battery life. Usually I snap the battery in when I need to charge and take it off to charge it separately afterwards.
thx for the answers.
that seems logical you cant charge a 3000mAh battery with another 3000mAh to 100%, you will lose something inbetween.
Lucky i don't really use my phone much, so i get 3-4 days with low usage and the normal battery ^^
I'm extremely happy with my purchase price. I complained because their site clearly says data sync supported but it's not. They offered 30%. I advised still nothappy because site misleading so they gave me full refund and let me keep the product so for free it's fantastic lol.

Hello, what about charging this case?
On brando.com ist that you must charge case and phone separately.
On some Chinese pages is that you can charge case connected to phone - phone will be charge first and than case.
Got the 4500mAh version now, why? Because it's supposed to charge the device at 1A

The case has a button so whilst your phone may always be connected it doesnt mean its using the case power so it never charges both at the same time. When you connect the charge cable to the case it will charge the case if its turned on or charge the phone when the case is turned off
