I'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.
I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.
I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).
Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.

It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.
Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.
Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.
That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.

They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.
The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
Update to the latest version in your area, uninstall those task killers and whatnot or do a factory reset, install the apps that you are going to use normally like facebook twitter and install better battery stats, decrease brightness to your most tolerable level.
use the phone normally and when the battery is low, use the tool provided in android to check if your phone is sleeping when the screen is OFF, if you are having wakelocks, then use better battery stats to find which apps are causing the wake locks.
No need to install battery management apps, or task killers or memory optimization apps (or as custom rom as yet), that would only compound you problem which may be a very small one to begin with
Thanks for the help so far guys. I've installed XXKH3 and flashed hardcore's Speedmod kernel, and am just getting things set back up the way I like them again. I'm going to uninstall the battery saving apps for now and see how the battery lasts the next couple days.
I'll install Better Battery Stats and keep an eye on any wakelocks too.
Thanks for pointing me in the right direction - it was all very simple and quick to get set up; the sheer number of kernels, ROMs, etc. is all a little overwhelming to me right now, being new to Android!

there are other tweaks with custom roms that aren't found in the stock rom (which provides better functionality).
btw, i also suggest u use setcpu to underclock your device to save more batt.

wow, good for you
I used HTC Desire before this device, and the roms on there actually hindered battery life, even with all the fancy underclocking, so I am betting, without even attempting to brick my phone, that they are just as overhyped on this phone too.
I get two to three days out of my phone, using it as a PHONE. I can send and receive emails and texts all day, along with phone calls and the occasional browsing and still get at least two days before it dies. I turn off data when I dont want it and stick it in 2G mode and it dares me to kill the battery.
Just let usage settle down and it's fine

That is wrong. I used to have a UGKG2 ROM and since I upgraded to XXKH3, the battery is MUCH better while the GPS pinpoints in less than 3 seconds with a 5meters accuracy.

Hi guys sorry for this thread new here so please go easy on me. Had a galaxy s2 for a few weeks now and i have to say best phone ever. Did the normal rooting and flashing roms and i have noticed recently that my battery has been going down quite a lot after a few hours. I tried roms like Villainrom, Cognition, Batista and etc which i find them very good but on my battery stats it says that i have high display usage and the percentage is like 56 - 85 and sometimes goes and stays to 91. i have since then when back to 2.3.3 stock firmware rooted it as well and i only have display percentage of only 25% which i think is normal and my battery lasts longer. I have spoken to Samsung regarding this situation and they are sending me a new battery but im just wondering why i cant flash a custom rom without having to worry about the high display % and what can i do to fix it? do i have to give it a few days for the battery to settle on the rom or shall i just stay with the stock rom for now till i get my new battery and then try to flash? sorry for the long essay i just need to find out if any one else had the same problem as i really like to use a custom rom that my normal one.
THanks
I too find it very hard on the battery with all the custom roms that I have tried out. I tried, Villain, Cogniton, LeoMar, Batista, etc..etc..etc. I have in fact tried out all the ROMs out here. Tried even different combinations of Kernel, but all only lead to the frustration when it comes to battery life. I finally tried MIUI ROM and I can say that it is giving me very good battery life compared to other ROMs.
It is interesting to note from you that the STOCK ROM has given you better battery life. Could you please tell me how long did your battery last in Stock ROM and what are the Apps that were running in it?
Install Better Battery Stats, I don't think anything wrong with the battery.
See under Wakelocks what apps/processes are going in background and causing the drain. Then take necessary steps with TB Pro.

to xdadeveloporian: thanks for your reply bk and sorry to hear that you had the same issues. like i said above i am very new to all this so apologies if i am replying with noobish comments. with wifi on and the normal widgets i had a battery life over a day. only charged it once and it still going. is that rom that you using now good?
and to ithappy sorry what do you mean by your reply i do not understand sorry. and do you guys think with a new battery it will fix my problems and i will be able to flash roms or do i have a faulty phone?
% is not important, what really matters is total time on for the display. Are you sure it isn't that the stock ROM burns more power in other areas, so the display is less? Or maybe the brightness is different? I'm not even sure how the display proportion of battery drain is apportioned - is there really a current sense integrator?
now that i have the stock rom with firmware 2.3.3 display is 30% followed by android os 15 - 19% which i think is normal into regards were i was on customs roms and the os was 15% and display 50% and over. brightness is basically at the lowest i can put it i am using touchwiz launcher and i only have two pages with widgets and nothing else. just a bit confusing thats all. i mean with custom roms the battery should be alot better not the other way round if you get me.
apologies if im not making any sense here. thanks again for all your replies it does help

I don't believe that stuff, why battery life would be better in a Custom ROM, because they added/modified some stuffs, nah. You can make a Stock ROM custom with some little modifications if you are rooted and have great apps like Root Explorer, Titanium Backup etc. I, for me, will never ever use a Custom ROM. But that's just me, don't take it any personally.
And about battery, don't see that how long are you getting with it, like- 1 day, 2 days, they don't make any sense, just keep an eye on the 'Screen On' time, if that is around or above 5 hours then you are very fine. And also keep checking that your Awake and Screen On bar is synchronized or not, if it is not then you must have something going on background, like- Latitude, Email exchange etc. which you can see under Better Battery Stats. And also, when not needed turn off, 3G, Packet Data, WiFi, Auto Sync, Background Sync and check how many apps are on Auto Sync, if not needed then modify it to Manual Sync.
Regards.

Maybe they fixed some bugs - specifically a custom kernel might have improvements or bug fixes (since there is lots of work going on here from many companies making contributions). This takes time to filter through to the official ROMs.
Maybe they removed some of the stock apps which contribute (maybe only slightly) to power drain.
Maybe the small differences in the ROM mean that existing bugs are less likely to have an impact, so even not fixing the bug it seems to have gone away.
Custom ROMs are as likely to make things worse - but if many people are affected then it is likely that someone will track down the reason.
Look all i know is that as soon as i started flashing custom roms on my phone my battery life has been going down like hell. Checking battery stats the most thing that is taking up battery life is the display being as high as 80 even 90 percent. I am not a expert on android having had an iphone all my life so when people say underclocking and other stuff its like new things to me so i do apologise for being such a noob. i do love my galaxy and i think its the best phone out there at the moment. all i need to know is if there is something that i can do to bring the display down and not to have it drain so much out of the battery..
Thanks again for everyone for replying
very niceeeeeeeeeeeeeeeeee
huh? has anyone else experience high display usage on their phones when checking battery stats?
is that from the android market i can get that app?

Hi.. my first experience with S2 has not been great battery wise. I've found the battery life to be horrible. Even with all the battery saving features i.e. static background, widgets off, etc. etc., I have to charge the device twice a day. Its practically useless. I was thinking maybe there's some 3rd party ROM out there which would improve the battery life? I'm currently running stock 2.3.4. Any suggestions would be welcome..
try mikimod"s rom its really good for battery, and also sicopat<s rom< and modaco i find they are the best for longer battery
I've used VillianROM, Cognition, and CyanogenMod. I find that CyanogenMod gives the best battery, but your mileage may (or will, most likely) vary.

You will get mixed answers. People run different roms with different kernels. Some do a full discharge/charge before judging these kind of things, some don't. In the end the most important factor will be apps and usage.
Try what works best for you. And post in q/a section next time.

Best Rom So Fare.........
( SensatioN Rom 1.8 )
( Based on 2.3.5 XXK13 )
this is none wipe Rom.
Excellent review..
Try It..
Hope you'll Sensation Rom.
Before trying other roms/kernels check to see which apps are draining your battery so much, as for dual core phones the GS2 battery is really good, so in normal situations you shouldn't have to charge the battery twice a day.
I'm in Wanam 5.1 + siyah kernels and as many other users i get +2 days of battery.
@antiochasylum I've hardly had the need to post. In any case, any moderator can feel free to move this thread to General. @Sesshou about 57% is display. Rest of the entries are all negligible. Yet the batter evaporates..
Why no one mentioned MIUI ROMs..?

I have tried lots of roms,the best battery life i have found is Batista70 FOXHOUND EDITION 2.3 with voltage control,it will take a lot too make me change again!
I use the Goatrip Rom 1.4 with Angelos Kernel Abyss 2.2
Look at screensshots, that says all :
Display on time was about 3:30h
3g On, Data no the hole time, i turn it om when i need it
1. pic with standard accu
2. pic with Samsung 2000mAh accu
Try Hyperdroid. Over 24 hours of medium-high usage..
I have been struggling with trying to figure out if the battery life I am seeing is what my Atrix is really capable of. I am occasionally a heavy user, but on weekends I am a very light user. I'll start at 8am with 100% and be almost dead at 6-8pm. I have searched around and seen other Atrix users with 24 hours of battery life and even if I tried my hardest to not use my phone I wouldn't get those kind of numbers. I feel fairly confident in saying i scoured search results and tried everything i could find to extend battery life.
Am I doing something wrong?
Is there something I can do to help?
I know it's been asked before, but I am hoping to get some current answers for this question: what kind of battery life numbers are you getting on your Atrix? Which rom are you using?
Atrix 4G running CM7 RC3. If the answer is "keep it charged as often as possible", it is what it is. It would be great to find an answer to why battery life is so much shorter than others though! Many thanks in advance.
Just noticed CM7.2 stable was released, upgrading to that now to see if battery life improves. Might try a full wipe to see if battery life is better without email, syncs, etc. etc. if the upgrade doesn't help.
i would recommend getting cpu spy and also download and install as a zip 'blue sleep fix' (blue sleep zip can be found in the CM7 thread). This has greatly improved my battery life.

You should turn wifi off when not in use, that will save battery life.
Badass battery will let you know how you spend your battery by % and let you know which app takes the most battery. (Lets you get a really readable easily understandable battery read out.)

turning off wifi is not going to help him that much. I leave my wifi on all the time no problems, make 2 days light usage no problem.
More likely he's got some apps running around in the background. I suggest he pick through what he's got installed and start turning off the things that like to sync all the time in the background.
I think step number 1 would be to install a non-stock ROM and startover fresh.
Blur-based ROMs (Nottachtrix was really good) then the faux123 kernel then slowly start installing the apps he likes to use and monitor battery life. It might take a month but he's definitely got an offender here or there causing these problems.
also install Juice Defender. My mom's Galaxy S2 was having tons of problems with battery life even though she wasn't using it at all, 60% battery life at 3pm without using it at all, installed that and immediately helped her a lot, like 80% by 3pm WITH use.
Also, clear your dalvik cache. After installing lots of stuff and not using it, it just fills up with sometimes poorly written code. Clearing it always makes phone faster in my experience.

I think this is what I will do today! I'll do a nandroid backup, and try Nottachtrix with no extra stuff installed or setup. I will report back! I appreciate all the help to get my phone performing where it should be.
Just wanted to report in. I tried a clean ROM as stated in my previous post with no luck. I just couldn't get past the battery life I was getting with cyanogenmod WITH all of the apps and syncs enabled. Should I try another ROM maybe?
Maybe your battery is just a bit old? After ~2 years, you can expect that battery life drops dramatically. if you are a heavy user this might happen earlier. Maybe check with the battery of a friend of yours whether it's a software or a hardware issue

You could be right, the battery might be dying.
I was on vacation the past few days so I got the opportunity to not use my phone most of the day (job requires me to use the phone a lot). The battery lasted about 12 hours and looked like it had about 4 hours left. So maybe I am expecting too much, but I'm not trolling...no.
If you aren't going to be helpful, go somewhere else. You could have said "Your phone screen was on for probably longer periods than the average user and that's why you can't hit longer hours". Based on your previous comments, I shouldn't expect much from you though.
Many thanks to all who are helping me. You're all awesome.

11-12 hours.
I also have 11-12 hours with 1 charge. And it is not enough for me. I use only Whatsapp ( a lot usage ), a little bit browsing, 20-30 minutes phone calls. These are all. And 11-12 hours is sooo bad for them i guess.
I have an "suspend linux process" drainage issue. Maybe because of it, I'm getting this result.
How can I extend my battery life. PLEASE Help!
New to the galaxy note, any suggestions for roms with good battery life?
blackstar☆ and pawdan for me opinion you try for 2 or 3 day and see who like you

I've tried every rom available here ...for the I717 ..
And "For Me"..
The best battery life comes from the following builds ..
Saurom ..GB 2.3.6 .....and ..
Flappjaxxx UCLF6 ICS Build #5.
But please remember, that I prefer zeam launcher, and use only a handful of apps and never Widgets.
You simply have to try the builds for yourself, and determine the best balance between performance and features.
But more importantly, the 717 runs best without overclock..IMHO ...and basically using a stock kernel.
Optimization of the build for the device is very important in maintaining a smooth and functional file structure....
That being said, I stick with slightly modified stock builds for the note, and I always disable the stock Touchwiz launcher, as I can confirm it's a battery hog.
But invariably, I feel that Samsung did an excellent job when optimizing GB, while ICS is larger and not as refined...and JB official will correct the ICS bugs.
We can only hope that Samsung releases the JB we see on the note 2....as it truly is an exceptional build.
Good luck in your flashing and optimization of the builds you choose ...g
BlackStar X did the trick for me. I also turned sync off and manually sync my email account. Turning data off also helps otherwise when screen is off battery keeps draining.
I'm also looking for a battery saving ROM. This is insane. Data is rarely on and it's almost always on WiFi. I'm a average to low user. Don't play any games, make a handful of calls a day, text more often. Screen is on for maybe a few minutes at a time.
Currently on Blackstar XI DXLJ2 and it's absolutely horrible. Gonna try Blackstar X and see if it's any better.

Didn't mean it like that! Lol. The ROM itself was amazing, but the battery life was the complete opposite. Again, ROM was GREAT!

The battery life is no different than any other DXLJ2 rom.

All roms are exactly the same on battery life... That is until you've tested it on your device.

Its how you use you phone and what you use on your phone that determines the battery life. From a development standpoint, there are minor changes that we can implement to improve battery duration. The difference will be negligible. You might notice an in increase in your battery, but again it won't be much.
ThE UnknowN
Yeah, differences aren't too large. For example, your screen on time will always be in the 4 hour range if you have a medium-ish brightness.
With that said, sometimes a ROM can have a bug and your standby time suffers. I've also noticed the battery curve is sometimes different so it would appear the battery level drops faster but then it slows down and the total time ( from 100 to 0) ends up being the same.

Holy crap. I'm lucky if I get 2 hours screen on, but thats with auto brightness. maybe I need to set it to medium brightness.
But I too have noticed some large battery differences on ROMS with the same base/kernel. I don't understand it, because as stated, the rom doesn't affect battery much.
I've since found a ROM, that with using it the same exact way, battery life is substantially better. That comment wasn't to offend a developer or get into a debate. Obviously a major part is how you use the phone, I know this.

You didn't offend me. Lmao. I probably know what Rom you are referring too. And I doubt its that it's better. I run all the roms and test them all. Pretty much the same all across the board. In the end it's the user who matters.So if you found a rom you belive is better for you battery wise, then kudos. Im glad you found a rom that works best for you.

Right on.
Back to basics shall we.

It also depends if you're using LTE. I should qualified my assertion with "just playing video using the hardware decoder".
I went I the play store and bought juice defender ultimate. Makes a big difference, well worth the money in my opinion.

Here's a little story for ya.
I started out using Ginger stock, the interface felt sluggish coming from an iphone4 (wow I haven't typed "iphone" in such a long time, I feel weird!)
After mucho research, I went for the Eclipse rom. Ultra smooth, gotta love it. Like every other rom (so I've heard), I still get random reboot, but very few, about once a week and sometimes don't get it at all. Battery life is crazily good, loses about 4% overnight with "interactive governor". Music player always stop responding on first open. But I can live with that, just kill app and reopen and it's good to go. Overall, using the Eclipse rom has been a very nice experience.
Then I tried Novena (ICS rom I believe), the interface wasn't as smooth as JB, the battery also drains fast for some reason (yes I have turned off every option that could potentially drain the battery), so I moved on...
Then I tried JellyBeer, smooth just like Eclipse but with more options. However, the battery also drains pretty fast, why? I really don't know, played around for hours but still couldn't figure it out.
At last, I came back to Eclipse, everything is almost just how I want the phone to be.
In retrospect, I hit the jackpot on the first try. But it is certtainly worth the attempt to flash a variety of roms, eventually you will find the one that delivers.
You do know it takes a couple charge cycles for the rom and battery to "settle in" with each other right?
You can't judge Battery life by the few hours you have a rom flashed.. which I bet you were playing with the phone the whole time as well setting everything up the way you like seeing what other options are available all that jazz, making it seem like the rom was killing your battery even more.
Pitting these FREE roms against each other when it really comes down to end user, is unfair to the developers who do this unpaid in their free time.

Be a man, some works and some just don't. Your mileage may vary.
To quote myself:
"It is certtainly worth the attempt to flash a variety of roms, eventually you will find the one that delivers."
Okay. So I am currently running shostock3 on my sgs2 with siyah kernal. I read the article from zedomax on galaxys2root.com that it has very good battery life and very stable but when i am running it, I have terrible battery life and i am currently underclocked or whatever the word is. Is there anyway to fix this?
My advice, run SHOstock3 as it was released. It runs great as shoman94 dev'd it.
...and stay away from that web site u mentioned.
Stick to XDA. Period!

Yes. I'm running shostock3 with the included kernel and get good battery life.

Getting great battery life on Shostock3 V3.0. Flashed the AJK 1.52s kernel. Checkout Better battery stats...see if you have wakelocks killing your battery. And..I agree that website is no good..stick to XDA.

Most people get really good battery life on SHOstock3. Just search the SHOstock3 thread for the word battery to see what I mean. If you're not getting good battery life, you need to find out what in your configuration is causing the problem, and fix it. There is a thread in the general section started by Entropy512 that you should study to help you identify where the problem is.
I was on GB ShoStock for a long time thinking ICS and JB would never leave me satisfied on battery life.
http://forum.xda-developers.com/showthread.php?t=1353513
Finally came to my senses and tried out ShoStock 3 and have never looked back. To make it short the best Rom Ive ever flashed for any device I have had in the present and past.
You definitely have a rogue app killing your battery, find out which one it is and uninstall.

Sorry you have battery life problems.
I have been running Shostock3 since it came out (it's version 3.02 today!), but I also been on and off at least five (wow can it be that many?) JB roms on my SGH-i777 (won't even mention the # GB roms here!). After trying many, I must agree with the other posters who state that this rom delivers very good battery life when compared to stock and when compared with other custom roms.
Lately, it has delivered the best battery life I have ever had on this phone using any rom (although SlimBean JB provided very very good battery life for me recently as well! Also UnNamed was great for battery life in the old GB days )
I followed the recommendations made by creepyncrawly to read Entropy's (& others) battery notes/faqs. They provide some really good background, some with that typical "XDA flavor" (read technical!. That material, plus some more plain old simple user adjustments to how and what I use on the phone have improved my phone's battery time; and it might help you as well.
It really boils down to the fact that each phone user loads different apps and our usage patterns vary.
Assume that you've flashed it and let it settle for a few days and several recharge cycles. After doing this you can see what YOUR "norms" are. They may be good or bad, but that's the baseline for you with this rom and with the apps and usage pattern you have.
(You can tweak voltage and speed (well, not speed on SS3!), but my experience has been that the more noticeable changes will be by adjusting your pattern of use, or doing the "hunt for the app" (or apps) that are burning down your run times when not in use.
Not many here seem to like or do this, but I would also try one of those "help-you-with-battery-use" apps --like juice defender (Ok, I get that many here seem to think it a waste, but it really did help me --a little-- when I used it); or get DS Battery saver (a bit more aggressive and noticeable, but you also notice the lag while you wait for things to turn on when you want them).
Actually, these may not be precision solutions, and don't focus on your specific phone app use, but they do work in a macro way to slow battery use and simply working with them for a few days or weeks will provide you with a better a sense of what the heck is going on under the plastic; they will cause you to look at what you have/run and when.
Oh, this includes using Better Battery Stats, which is fine for reporting out exactly which the apps behave --or don't-- and by how much and when. I'm not slow (well, that slow but it frankly, it took me quite a while to figure out what I was reading in the BBS readouts and what they meant! (Now, after a year+ or so of using it, I don't even have it loaded, since I've done the fiddling I need --and BBS, plus those other battery apps, helped me to figure out what apps worked well, what apps I was willing to sacrifice battery on and what apps were useless and should be tossed.)
Finally, some roms just don't work for people! So it's not worth the frustration chasing something you may not be able to achieve with this or another rom. (You probably read how individuals have problems that you don't -yet, you run the same rom and the same phone! That is our world. So, too, you will read about some who make amazing claims on how long they continue on one charge. Some are pretty amazing, and some may even be real
My final five cents would be:
#1 run the rom a couple of days, get a baseline. Then switch from Jeboo kernel to AJK's latest for TW (I think it is 1.25ss, but I really also had great results from 1.48s) and run it a few more days. They were pretty much even for me, but others find one or the other kernel makes a real difference!). Compare after doing the same activities through a charge or two.
#2 If your battery life remains "poor," note what poor really is (ex. how much screen time? and how much total run time prior to getting to zero or 10-15%? ...something like that).
#3. Then get BBS and one of the "automatic" battery-saver programs and work with it for about 4-5 days and that many recharge cycles. See what your norms are but do it for the same type of usage!!! If better while using the battery fixers, then you can work at picking off the app or apps that are sucking your battery more than you want. Not as tedious as it sounds. Of course, staying with a rom for three weeks might be a challenge :laugh:, but this is a nice rom to work with.
#4. I don't think you will need to under-volt to get good BL. I wonder if your phone is stable in doing that? Or, does it induce additional lag? That might be a high price to pay for more run time. (You could compare the UV results with your "norm" as well!)
#5. Finally, we are on Galaxy S2 Sgh-i777 -and can change batteries all day long for not so much per battery! It is not elegant, but it works. (Done it myself several times -even with good battery life).
Good Luck!
Best ROM, Good battery life... been with Shoman's ROM since shostock2 never have a problem with the battery life...
