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?

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.
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'm using Seraphim and I'm happy with the battery life. It seems to be worse than the GB ROM but I can get about 2% down every hour when the phone is idle.
I am thinking of trying different ROMs and battery life is very important to me. Which ROM will give the phone a better battery life based on your experience?
Thanks.

ah ok, im in search of a good ics battery friendly rom as well, actually downloading dag's ics "hybrid" rt now. i'll give it a go for the next couple days and post back. i was seeing about the same as you for seraphim.
In my experience, unless there's a bug, a ROM has little effect on battery life. Android is going to use a certain amount of power to run itself, and there is little that a dev can cook into a ROM to change this. Beyond the system, battery usage is from the screen, apps, and radios. If you are in an area with poor reception, and have lots of apps and widgets that frequently update in the background, this will decrease battery life.
I've used both DaGr8's Alpha II and Seraphim, and my battery drains less than 1% per hour when idling.
Guys a Search would have told you that Battery life is 99% on the user and has almost nothing to do with the rom. We could be running the exact same rom and get very different battery lifes due to the apps we use and how we have the device set up.
In the end there is not best rom. Only what works best for you.

Hello,
I'm running 2.3.6 now and I wonder if I switch to 2.3.4 will I have less battery drain? Are there any functional lacks on 2.3.4 comparing to 2.3.6? However, I use GO Launcher on rooted phone.

Well next time please do post questiona in the general sub forum Anyway I think it is better to just update to 4.1.2 since you are rooted anyway. I get better battery life and signal on 4.1.2 compared to 2.3. My choice of a rooted stocked based rom would be NeatROM Lite by Sale :good:
I agree. Generally, upgrading rather than downgrading will increase performance so I would just go wit a higher version. Also, if you feel you have an unnatural battery drain, there are other options except switching versions to handle that. Maybe it is one of your apps that causes the battery drain. Other possibilites are sync cycles or kernel. If you switch to another kernel that might help your problems better than switching ROMs (although switching ROMs is always recommended, just for the fun of it )
gulypi which
I don't know if I am doing something wrong, but I just flashed NeatRom 5.0 and the battery life is terrible.
From my point of view, 2.3.4 stock with speedmod kernel was the best with my s2. I had battery life for 2 days. With latest roms I have battery life for max. 24h. I always did a clean install with factory reset. Don´t know why the battery life is so bad with my phone.
But now I ll give it another try. I will format the whole phone and try sentinel rom again which i liked most
NeatRom 5.0 killed my battery also. Trying 4.9 for now as I jumped from 4.6. If it's buggy I will switch back to 4.6

Media scanner fix for battery problem on neat ROM should fix this. Also Apollo kernel is great mix with any stick Sammy ROM.
I don't know why flash modded kernels (at least if you are about to have better battery life, not other mods)? I have plain stock GB 2.3.6 XWKL1 (DDKL1) and just use Go Power Master, Set Cpu and calibrated battery.
At first when I went back from ICS to GB battery lasted for 14hrs. I charged battery fully on and battery "learned" new system and went up to 23hrs. Then I calibrated battery: fully discharge till phone went off, again started, playing till off again and again till it won't on. Then without turning it on I charged battery fully, unplugged charger, waited till battery went to 99% and plug in charger again till 100%, and again. I was using WiFi over half time of usage, flight mode at nights, play wit phone settings, installing apps, browse internet a little, use as phone as usual, listen a music a little, browse photos, etc, and battery lasted for 39hrs on stock battery which previous owner using for last two years and he didn't care about healthy battery usage. I got Samsung Extension Pack with 2000mAh Battery and flat back panel but it waits for new S2 I bought yesterday. I will put new battery after ROM flash and get all restored to state I have now, then I calibrate that bigger battery for new phone.
But anyway, question was if someone was playing with 2.3.4 and 2.3.6 stock ROM's in order to achieve better battery performance? I read somewhere that guy had over 4 days on stock battery and 2.3.4 GB. So I wonder if I switch to 2.3.4, which may be probably less demanding system than 2.3.6, will I get more time on one charging? I don't care about how it may or not look like cause I use GO Launcher anyways, but does it have same stuff and functionality as 2.3.6?
The problem with comparing your phones battery life is that it's depending on too many variables. You can't just say 'My phone lasted 30 hours with this and that usage', because everybody is using it differently. If you really want to test it, flash both versions yourself and try.

In addition to Donnie's very good point, you're asking about 2yr+ old firmware. Do you realise how few people on a site like this are actually running firmware that old ? You'd probably find a fair number of 'ordinary phone users' out there who are still running GB because they may not be technologically au fait enough to do an OTA update.
At the end of the day, changing firmware to squeeze every last drop of battery life becomes a game of diminishing returns in that you can spend a lot of time to get that last tenth of a % of use out of every charge. You have to ask yourself is it really worth it, or is it worth simply enjoying your phone & chucking it on charge every night (or if you really chew through battery, getting a spare).

Well, the thing is I don't understand why people update their phones and then complain about battery life if 2.3.6 works fine from what I observe here and there.?
As per Donnie's post, there's too many variables involved to say 'This Android version will definitely give you better battery life than that version'. Personally, I get better battery life out of JB roms than I ever did out of GB or ICS roms, not that I got poor battery life out of either of those though. And the reason for that is I worked at it.
There's no magic simple A-B-C to better battery life, regardless of what rom/kernel/Android version you're running, you have to experiment & try stuff out to find out what works with the way you use the phone/have it setup.
People who complain about battery life & attempt to pin it on the particular Android version they're running tend to have a really poor understanding of 'how it all works', because it isn't that simple as I've said.

People can also update their phones because of other reasons than battery life. ICS was the best for me with battery usage, but after JB downgrading isn't an option for me as I would miss to many new features and other additional functions.
The choice is yours to make. If you are satisfied now, I would stick to 2.3.6 if I where you. If you are curious about other versions -newer or older- try those
