hi just wanted to ask if there is a ROM there that is as close as the original ROM of the samsung galaxy s II in terms of apps and looks but is tweaked for better battery perfomance?
cause my dad bought a SGSII almost a week now, and we only get about 5-6 hrs of it using only it. already did about 4 charge cycles. (4 only cause most of the time the GSII is off, my dad's getting a hang it yet)
config:
- stock android 2.3.3
- 3g auto
- auto backlight (but we are inside a mall so the backlight is isn't that bright & have strong signal)
- auto sync is off
- background data is on
- haptic feedback is off
- audible selection is off
- fast dormancy is off
- power saving mode is on
- juice defender app in balanced setting
apps running:
-skype
-messenger
it drains a LOT even in standby a lot more when using it (browsing, not yet chatting). my hd2 is much more efficient knowing it is not a native android smartphone...
is there a tweaked battery efficient rom there that is as close or at least still looks as the stock?
You can do three things,
1- Install Better Battery Stats and see under 'Partial Wakelocks' to see whats running on background.
2- Stay on Stock ROM and flash a kernel which allows Voltage tweaks and install SetCPU and Undervolt CPU. Ninphetamine 2.1.3 is such a kernel.
3- If thats too complicated for you, then flash an Undervolted kernel, like SpeedMod.
I won't advise you to change to a Custom ROM for battery backup betterment. But doing the above processes will certainly save some.

thanks for the quick reply, so custom kernels work with the stock rom...i thought it won't. i'm not that familiar yet with native androids cause in HD2 most of the undervolted kernels there are already built in the roms so i don't change it that much now with the NAND builds....but anyway, i'll try for the mean time # 1 & 3....i'm not that into that #2 tweaks yet in a phone that is not really mine....
It is proven that Stock ROM's with custom Kernels have sweet battery life. As with Stock ROM's they haven't tweaked anything, it's just stock and you flash what YOU want, whereas a custom ROM you're getting things you dont infact need.
I keep going back and forth from Custom ROM's to Stock ROM's.
Hi
I would also recommend looking at SicOpat's ROM (http://forum.xda-developers.com/showthread.php?t=1183774)
This is essentially a stock, rooted ROM with a custom kernel and I find it exceptionally good.
The other thing I would recommend then is to install Titanium Backup and freeze/uninstall a lot of the Samsung apps - WiFi Sharing, software update, *hub stuff. Removing these has a very positive impact on battery life.
Hope this helps.

I have also been troubleshooting poor battery life on my phone. I used to lose 10-15% an hour just idling. I reflashed Stock KH3 with the KH3 CF-ROOT kernel and reinstalled a few things (twitter, yahoo messenger, google voice, and some apps that don't sync data). Currently I had 18hrs now with 60% left. MUCH better. A lot of the time the phone was idle but I did listen to music, play some games, and browse the internet/chat, use wifi a bit. Phone only lost like 4-6% overnight. (sorry I don't have hard figures but I didn't document any of it on paper). I'm trying to find out what was killing my battery so I am installing things little by little but I would definitely recommend stock KH3. Seems great so far.
I think your problem lies with the wifi-sharing battery bug. I hear this is updated in newer roms. This was the biggest battery hog on my phone, but after noticing it, my battery life is excellent now.
When Wifi is turned on/off this erroneous process starts in the background called "Wifi-Sharing". It hides and drains your battery at a VERY fast rate. The remedy is simply to "Force Stop" this process after you use Wifi.
Let us know if that helps.
You could root the phone and install Titanium to freeze this process permanently.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
sorry for the wrong forum i got messed up in opening a lot of samsung galaxy sII threads....
i dont see the "wifi sharing" in my dad's GSII when we used it. and as with kies, i think JKG2 firmware is the latest, so i assume that the wifi sharing bug has been fixed there, yes?
i know it would consume a lot since the GSII has a big "engine" but i didn't expect it to eat a lot even on standby with only YM and SKype messengers running in the background.
i'm still observing it. i'm still running stock.
EDIT: i just used wifi to download an app then when look for running apps, i saw "wifi-sharing" is running but i didn't even turned it on
i just flashed Speedmod T38 kernel (it seemed less complicated to use ) now observing if my dad's SGSII gets better

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

Beware using anything that isnt ondemand on samsung phones, can cause stuttering, that's what I found anyway.
As far as undervolting -25 to -50mv is a safe first bet.

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.
I've used ninphetamine 2.1.3+ and it used to drain my battery a fair bit. After having seen another user who said he was experiencing better battery life with ninphetamine 2.0.5. I flashed the older version and it turns out to be indeed better.
My idle drain rate is now 15-17mA using Battery Monitor widget.
So when put in picture. Drain rate is about 2% per hour with minimal usage. (Note 3g data was on)
Anyone else have a better kernel?
EDIT 1:
I've tried using SiyahKernel (KI3) and it seems that according to Battery Monitor widget the idle battery drain is 14-15ma. Seems to be much better. However, occasionally the touchscreen freezes and only the touch button works. But then again it could have been because I was using the KI3 kernel on a KH3 rom. Would report back after I finally get off my lazy ass and flash a KI3 rom
EDIT 2:
Got off my lazy ass finally. Flashed LeoMar 2.7.1 rom with SiyahKernel 1.7.8. Will report back after a while. Though I must say that for some reasons after the boot animation the phone turns black for quite a long time (1-4 Seconds) before the lockscreen appears. This did not happened with the default LeoMar 2.7.1 kernel. Will report back in 24 Hours.

Thanks sherlock. I posted my findings and was asking if anyone else had better. If it the time of the month of you. Stay off this forum.
Personally I find it very difficult to make meaningful comparisons, especially at idle.
Battery Monitor Widget gives estimates and not actual current drain. See this thread for some discussion: http://forum.xda-developers.com/showthread.php?t=1056486 but basically it's either not in Samsung's battery driver or the app is not reading the information. So you are comparing estimates and the margin for error might be pretty large.
When you flash new kernels you also need to recalibrate the battery. That also affects your battery drain estimates. (I've had Battery Monitor Widget tell me my battery is going up when its unplugged, so go figure.)
Battery life at idle is affected by so many factors. Maybe your signal strength is better one day than another. Or you got more emails or did more syncing. Or one app just happen to glitch and have a very long wakelock. If you get battery drain, you should be checking your partial wakelocks with BetterBatteryStats. Did you get more partial wakelocks when you were running Nin 2.1.3? Is it the kernel's fault or did you just have a misbehaving app?
I like experimenting with different kernels too, so my point is don't expect miracles when somebody says Kernel X gives amazing battery life compared to Kernel Y. Personally I think they are all about the same at idle, and the big differences are in your settings and your usage. If you wipe your phone, don't add any Google or Exchange accounts, and don't sync or download anything, your battery will last 3 or 4 days on idle no matter what kernel you use.
Stock rooted KI3 (cf-root) is the best for battery life for me, i also have constat 3800+ quadrant score (with top of 4109 as my screenshot in leomar 2.7 rom thread).
Also i have the phone a lot, but really a lot less hot while gaming or stressing it.
KI3 stock kernel and SiyahKernel are at the moment the best in battery life. Anything else is running on older sources and drain more.
The best for me is SpeedMod! Smooth and long life battery. There is something you can't do (bootanimation oc uv bln) but simply great!
Inviato dal mio GT-I9100 usando Tapatalk
best results for me: stock kernel reflashed after rooting, for that stock rom.
Bar none the way to go.
Stock Rooted KI3 does look good, am yet to test it though
Hmm. So seems like you guys are experiencing deliciously good battery life with KI3 kernel. I shall try it and report back with some numbers.
try siyah kernel. one of the fastest growing kernels IMO
For me is Ninphetamine 2.1.3 and now i'm trying SiyahKernel 1.7.7
My question is.. between stock ki3 and SiyahKernel 1.7.7 the difference is really small (barely notice it) or big?
I tend to not flash to much kernels since the very small chance to corrupt the efs folder (even if ofc i have my backup), so if it's only small improvement, i stay on the stock ki3, if it improves a lot, i prolly try it
I've been using the siyah kernel v1.7.7 and I've been experiencing a great battery life. I didn't use the stock kernel for long to make a comparison but I sugest you give siyah at least a try, since you can always go back to stock if you don't like ir.

Alright. I've finally got off my lazy ass and flashed a 2.3.5 rom (LeoMar if you must know) and am currently using siyah 1.7.8. Will report back within 24 hours after I've put the device through a day's use.

Pix or it didn't happen
Hi, I posted earlier saying that siyah 1.7.7 gave me good battery life. I tried now the cf root v4.2 KI3 and I had better results. Well, I'm someone that don't play many games, but I surf a lot and download a lot of stuff on wifi. I don't care much for overclocking so I think I'm going to stay wth KI3 cf root. For me they're both great for battery life, and maybe the other ones I have not tried are great also (speedmod, ragemod, ninphetamine...)
I think what happens with kernels, and this happens also with custom ROMs (and everything really, brands, etc..) is there is a lot of fanaticism. People like to choose one ROM and kernel and stick to them. They start to defend the kernels they use convincing themselves they're the best no matter what. That is in my opinion the reason because this kind of discussion turns meaningless. Well not that meaningless, at least it gives an idea of the kernels people are using, at least we know speedmod, ragemod, siyah, nimph, are all great kernels.
I'm not criticizing anyone, in fact, I'm just another example of the people I described.

I have the same phone. I'm using stocklite v2 very happy with it. Installed an ICS theme and did some additional customizing using UOT Kitchen (google it). Works like a charm.
Don't forget to make a backup before installling any roms.
success
Using The End 3.0. Tried Stocklite (both vsns) but battery life didn't noticeably improve. Tweaked my settings on TheEnd and it's comparable to those ROMs now. Not sure how my phone model changed to the regular GT-S5830 though. No more "D" now. I guess that has something to do with the kernel changing?

totally agree with ZACQ8
You can get a 2450mah battery that doesnt need a different case. Also try Android Assistant, you can view processes that are running and sort by cpu usage. Try to remove or atleast kill from startup any apps that do not need to run all the time. Most battery assistant programs do not work as after killing an app it will just load back up a few minutes later.
I got the official 2000 mAh battery which did give 15% more life. However the most effective improvement I got was from using the SpeedMod kernel and using Tasker to be more precise about when things came on.
Went from around 14 hrs stock to 30+ hrs for SpeedMod on stock rom for GB.

Hi,
To avoid too fast draining, some classics advices are to turn off some functionalities when you not need it, by example Auto Sync. Many applications needs to be configured with less frequent synchronization (weather apps or widgets, email apps, news apps...)
And as it was mentionned, some kernels can dramatically improve your experience. I agree that Speedmod is one of the best kernel to preserve battery. You can flash it easilly via CWM.

Hey friends I am currently running the OMEGA v28 4.1.1 JB ROM on my international GS3 i9300 and it is also rooted of course and I don't think I'm being paranoid but my battery life has took a massive drop since rooting my device. I am not overclocking mu CPU and I have tried out some rooted apps like battery saver for example and I actually think it made it worse. I have all the usual setting disabled to allow for optimal battery life like brightness right down, auto sync off, wi-fi off when the phone is locked I also only use the wi-fi manually if and when I need it and all that good stuff like smart stay and vibration off. I am wondering if anyone knows of something I'm not trying???
Had it charged to 100% this morning at 9PM and by 1PM I'm down to 79% already and I haven't made any calls and only used it to check my email and facebook for around 10 mins!!! is this normal for everyone else???

Did you reset your battery stats? Charge to 100%, reset battery stats from CWM or delete batterystats.bin -file, let the battery run out.
You might want to use currentwidget to log your battery usage.
I noticed big battery drop between 4.0.4 and 4.1.1 used to get 24 hours one charge 4 hours screen time. Now I get only about 12 hours.
Might just be me :/

I'm using also omega rom v28, have it installed recently. I cannot say how good is the battery with this rom, but so far I have like 56% in 20h, with 2h screen, sopcast 30min, voice cals 37mins....etc (also using wifi manually when needed)
Try out different roms and find out what works for you.
You can also use an app like BetterBatteryStats to check what's draining your battery. Its just to check whats use power.
Don't use batterysaving apps most of the time they are making it worse
I'm running Omega ROM V27.2 and yes it's normal to have a difference about battery life between ICS & JB.
To improve my battery life I installed the phenomenal extreme kernel, and now I'm totally happy with it. You should take a look to its topic in the GS3 Android Development forum. The dev developed 3 versions of his kernel to fit to most of the phone.
Also as others told you, you should get BBS app to point out the wakelocks & define which app is your problem.
Personally, I'm at 45% charged, and already used it during 21h 10m including more than 2 hours screen on. My auto-sync is always on and my WiFi only when I enable it. I'm using a live wallpaper and a lot Twitter.
When I do nothing I can reach more than 2 days.

Hallo,
I have the OMEGA v28 4.1.1 JB ROM flashed on Thuersday and i´m testing the ROM at a long time.
I use the Phenomenal4.0Medium Kernel and i must say the BatteryLife is very good. I`m working over 15 ours with him and i have 58 % on it.
My WIFI is every time on and Autosync when i use my calender and planners. For me a good app handdling battery life is "GREENPower" in Market Place.
But it´s my idea.
Here is the Link for the phenomenal kernel in xda android Galaxy S3 Deverlopment:

As he recommends ...identifying and reducing your wakelocks should be your primary concern. Been reading loads from developers that the insecure jb kernels themselves should already provide good battery management.

i can't get more than 2h and 30min display and 14h stand by. I have tried perseus, siyah and speedmod kernel. Using wanamlite rom.

that is exactly why i reverted back to ICS.........JB is nice and smooth but "eats" battery quickly.........now,battery life problem on my i9300,solved
Hey guys, if you are going to use custom ROM's you should be prepared for bad battery. The developers are adding so many different features and hacking certain apps to make them work in their ROM's without a lot of investigation into what the reprecussions to battery are. I used to always use custom ROM's but haven't installed one in about 6 months and haven't any problems with battery life. I have the latest JB on my 9300 and battery life is very good. I use GSAM to watch apps that want to go rouge and start sucking battery life. Media Player Service is a big offender as is Facebook. Also stock widgets that get placed by these JB ROM's are always pinging for new data and kill battery quickly. Get rid of them! If you have a stock ROM and are getting bad battery, 99% of the time it will be bad apps, your job is to determine which ones they are and apps like betterbatterystats and GSAM work great to help diagnose the issue.
can anybody else confirm the above post? because i am not sure about the custom roms.

I will soon have an S3 so I cannot speak specifically about this device / ROM(s).
What I know from using a lot of Android devices and testing original ROMs vs. custom ROMs:
- original ROMs have too much garbage built-in apps and are slower
- original ROMs have everything working
- custom ROMs are much cleaner and faster
- custom ROMs have (too) much problems, something always not working 100%
- custom ROMs usually have stability & battery issues
My personal advice:
- install latest ORIGINAL ROM.
- root it
- install the free app "App Backup & Restore" from Google Play
- search unuseful apps from Samsung (& others) and block the autorun of these apps (note: do not block basic android or samsung apps, as phone, contacts, etc)
I use this method for 1.5 years and this way my Android is clean (you can save over 100-150Mb RAM), FAST and much better battery. Try it.
In the end, if original ROMs have too many original apps, custom ROMs have to many tweeks that in the end, for my taste, the original ROMs + App Backup & Restore win hands down.

I have always had custom roms on all my android devices but at the moment I am running stock ics in my s3.
I don't think the S3 needs it.
To be honest I find a lot of the stock based roms full of changes I don't really need, ARHD was a great Rom but recently has started to lag really badly for me (and some other users) so I went back to stock just to see and so far I can't complain. Smooth, fast and the battery is as good if not better than the custom roms.
If the camera didn't suck so bad on AOSP I would be there in a instant
