Hello!
My sgs2 battery lasts for 5-6 hours
Im not using it that much. I play games for 30mins and thats all. I don't use it all time.
I was thinking that battery is broken so i bought another but 2000mah and it didnt help too but lasts one more hour . Im really worried.
I have mA usage widget and it sometimes shows 600mA 300mA screen off 200mA.
I've frozen all unnecesary apps.
I have kernel siyah 2.6.7
Can someone help me?
Check for wakelocks.
[APP] BetterBatteryStats adds battery history back to Gingerbread.
Thanks but i dont think it will help

Brilliant. Carry on enjoying your 5-6 hour battery life then.
very funny
It will help also have you checked what is consuming battery? Do you have data, wifi or bluetooth on?
Sent from my sgs2 running cm9 using xda app
Yes I checked everything. I have wifi bt 3g off, screen 40% in battery usage it says screen eats 70% battery and the rest is some apps 2-3%
You were given a way to possibly increase battery life from Oinky, and you dismissed what he said with "Thanks but I don't think it will help" ?
You're obviously an idiot then. And frankly, you don't deserve help at all after that.
Do you realise BetterBatteryStats is probably the best way to nail down wakelocks that can chew thru battery, once you've taken a look at the really obvious stuff ?
Clearly not.
"Some apps".
Very helpful. These apps don't have a name then? Too lazy to type them? You think we should guess?
You don't seem to want any help.You definitely don't deserve any.
Best keep your charger handy.
1. Are u using a task killer..if so don't
2. Are u rommed? It could be that theres one on x10 that ate my battery n am on a 2.6k mAh.
3. Ur kernel.. if its oc cud be a problem.
Turn mobile data, backgroud data, auto-sync and of couse your brightness, can save battery, if all this fails i suggest seeing your phone provider about it
Xperia x10i
DonutHD
DoomKernel v6
Unlocked and unbranded.. Bye bye vodafone
I would give you some help on it but I don't think you will think that would help.

I've given you your first "thanks" because you've made me laugh quite hysterically.
Hope you're battery's down to 5-6 seconds soon.
Check out a poster here who goes by the sadly inappropriate name of TheMegaStar - you two are made for each other.
Original poster seems a funny guy, don't think he wants our help.
Check for wakelocks, change your modem, try a different kernel if rooted, try a new rom if rooted, don't use any task killers.

I have a problem with my battery I have my new sgs 2 and I rooted and did a new rom and all but my battery is draining really fast under moderate use! 3 hours of moderate use and I lose about 30% battery! What can be the problem? I calibrated and did speedmod kerenel, still heavy drain... in sleep mode I guess it can last like 2 days but I want to use my phone constantly without loosing so much battery
Sent from my GT-I9100 using XDA App
As far as I can tell based on this information, you have no drain. It's normal that the screen consumes power. If you standby time is 2 days, then you have no battery drain.
Lower your screen brightness and avoid using white colours. And no there is nothing else you can do.
But I see slot of people who get 10 hours of use on moderate and even heavy use,.. maybe it's my rom? I use rarity rom with speedmod kernel, maybe I should use checkrom?

No one gets 10 hours with screen on. Thats what you are talking about right? You get 3-4 hours max.
So 30% in 3 hours is normal and not bad.
Right now I got left 58% battery after almost 3 hours of moderate/ heavy use like YouTube mostly fb internet n stuff, is that normal?
I got almost half brightness with 3g always on
Sent from my GT-I9100 using XDA App
Yes .
So is there any particular rom that is known to save battery?
Sent from my GT-I9100 using XDA App
yes, there is a way to save more battery - use common sense.
Srry I meant to write rom but galaxy must have "fixed " it
Sent from my GT-I9100 using XDA App
Whichever ROM makes you not use your phone. Probably best to choose the worst looking one you can find, so you're less likely to use it.
You still don´t understand it. The screen uses power. No matter what rom/kernel you use.
I do get it but isent there any rom that actually saves battery?
Sent from my GT-I9100 using XDA App
No there isnt, at least not afaik.
Get urself Android Assistant, switch to Tools and check out Battery Use. If u click on the "Other" button u'll see exactly what drains the most power. I'm almost certain it'll look like this:
Display
Android System
Android OS
Display can only be reduced by brightness, auto-rotate screen and Auto adjust screen power (See Display settings)
Android System includes many packages. (Look up the details in the Assistant to see which ones u can kill for now)
Android OS is mostly ur CPU clock. U can get urself SetCPU (root required) to lower ur clock frequency (mines set to min 200/max 800; on demand). Everyting runs smooth and I dont see any difference besides 2-4 more hours of battery
Dont set it too low or it wont start up anymore!
The Assistant quick boost widget is also pretty useful. Just click on it and it'll kill all unused apps increasing ur TTL, even if its only a lil bit.
Hope this helps!

Nah. I might be a **** about it when it looks like someone hasn't even tried searching with google or in forums, but I still try to be mildly helpful when I can.
Look for post speaking about Betterbatterystats.. it's great!
I flashed CM9 on my GSII on Friday and ever since it's had 5-6 hours on usage. I've tried doing the battery calibration stuff, seemed to be better Monday and today it had 50% after a few hours of gaming so that seemed normal but then i reset it and it dropped down to 10%. I tried calibrating again and still 5 hours.
I've been using that Battery Calibration app and it game me 40% charge at ~3500mV. I'm not sure whether that is the battery volume but seeing as 100% was 4200mV something seems wrong.
Anyone have any ideas?

It isn't ICS, i flashed it on a friends GSII at the same time and his last 1-2 days like usual.
i´m test ics roms, and have much differences between them.-
maybe the kernel makes the difference.-
But is a fact that GB has better battery management, that ICS

I have an LG GT540 as well with ICS on it and that would get 8 hours regular usage with it. My GS2 get's less then that without me using it.
Ok you compare with other device, i Spoken to Galaxy s2, Ics have bad battery management, in sleep mode.-
But I´m still test the slim rom with neal kernel and have 53% battery after 30hs. with a general purpose.-
try it this rom an kernel,.-
As was already pointed out, bad battery life is almost always a rogue app keeping the phone awake, install Better Battery Stats and CPU Spy to monitor wake locks and deep sleep, if you find a problem with an app keeping your phone awake, uninstall it and your problem will likely go away. Personally, I've been running CM9 and other variants of ICS for months and I get less than 1% per hour of drain while the screen is off and the phone is asleep, this is better than Gingerbread was.

Yes, gmail, facebook, etc... Remember that I said screen off, obviously screen on drain is considerably higher.

Right, but background sync can still hit the battery, even with screen off. I was just curious.
Ive had days with horrible drain but it was almost always an app doing something dumb and keeping the phone awake, bad cell reception or a noisy wifi router. The trick being to identify wake locks that seem suspicious and track them down.

It's always better for everybody to support the developer by purchasing it on the Play Store, I did it.
It's a thing of principles, if you support developers they will keep improving apps and making our lives more enjoyable with our beloved SG2.

I agree with you, I was just trying to help the guy out who was asking for it.
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.

Which kernel? Flash Faux 1.0GHz and undervolt across the board by -50mv. Instant battery life!
Also, use ROM Manager or equivalent to stop all non essential apps from starting on boot.

Err, that is not good battery life at all bro. I can tell you barely used the phone. Atrix should be able to provide up to 2 days standby time...
I wouldn't undervolt either, I read on these forums that the battery gained from undervolting barely makes a difference

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.)
I can help you get even better battery if you use this app and give me some numbers (it has a share via gmail/etc)

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
Nvmd
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.

How can I extend my battery life. PLEASE Help!
Hi all, I was trying to post this question directly in the forums but looks like i have not permissions to post on the developers threads since this is my first post :crying:
I have a question about battery duration with the omega rom on my SGS II.
First i flashed version 16.2 and i saw my phone's battery life was not very good (10-12 hrs average). i thought it could be all the things this JB rom can do (like smart stay and all that kind of stuff) so i went back to the Omega ICS v15.1 but same thing with the battery life, i wa doing at least two recharges per day. Then i saw that the omega v17 was released so i decided to give it a try hoping thing will be better.
I alredy did the rescvan media root app thing, disabling sync, and all those tips with no difference.
Am I missing something, does my battery needs to be replaced? (i bouthg the phone like a year ago).
And what is the average normal duration with this ROM?
Thanks in advance!!
(I'm attaching an SS of my battery stats)

Hi I'm in a similar position on a jb ROM also get not many hours 10-15 as u can see nearing 6hrs will probably get some where between 50-60% battery it just feels like it drains fast when I use it and when its on sleep as well. I'm also doing all the tweaks to save battery life changing govenor turning off sync killing apps low brightness etc. Still feels like short battery when phone being used or in sleep.
