You're totally right, there is no topic at all regarding battery issue on SGS2 ...
Who is useless ?
Battery drain its a question of reading the varying fixes and or reasons why and trying them out .
The post regarding Android OS battery drain may help or not .

Yes, this phone has horrific battery drain. I recommend you take it out to the nearest field, strap it to a rocket, and shoot it into the stars as soon as possible.
Or, you can consider using the search button or follow the MANY links the nice gentleman posted above for you.

Lol maybe the battery will drain less in an area with very little gravity.
On a more serious note does anyone know of a list with apps that are safe
To freeze or even remove? I've been looking through the above posts for about an hour and can't find
Squat.
Edit : holy crap I need to open my eyes, its stickied at the top of the general section.

Yea I saw. See my edit. Feel silly now lol.
Just do a factory reset fixed all my problems and my phone came with KE7 installed I didn't upgrade to it.
Battery life went from 10 hours to a day and a half
after lot of tests, i discover that was the calendar sync. In idle mode my phone drain 5-7% per hours without 1% per hour.
After I uninstalled all the useless battery draining system apps, my system doesn't use alot.. like 2-5% , but my screen is getting 50-60% everytime!
I allready tryd different settings, but still, it attacks.
Do someone here have a friend with a SGS2 with good battery life !?
Try to change the battery for 1-2 days and see if its better or not, so we can know if its the battery thats need to be changed!!! report pls !

I doubt EVERYBODY that posts in these forums have a faulty battery. It MUST be software related. So many "faulty batteries" would be a great cause for concern.
from my understanding its 50% user and 50% the version of gingerbread were running.
Im coming from an atrix which has great battery life. A little bit of optimization which the great devs are doing is definitely helping.
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,
i checked the forums and found no solution. i am on stock 4.2.2 leak and the battery life is better than 4.1.2 however, it still doesn't compare well to what other people have posted.
i see some people showing screenshots showing their s3 lasting for 2 days... i am wondering am i doing something wrong.
here is what i get after a day at work (see attached)
thanks
Battery life is something on which you will get a million views/opinions/results. Depends on your usage, uc, uv, brightness, apps you use etc. For instance I don't get more than 3 hours screen time while people here get around 6 hours. Battery life is something you can work on and tweak to make it last longer.
Hope this helps!
Sent from my GT-I9300
i am on stock kernel though rooted so no uc,uv brightness is set to auto with -5 (not sure what that does but on the 4.2.2 leak it made the screen dimmer), i suspect it might be the apps draining but .. what use is a phone without them...i use llama for location profiles and avast antivirus(not sure if really needed), also facebook set to not sync,gmail set to default push and i play games occasionally.. as shown from the image less than an hour total.
oh wells ... i was just wondering how do those people get 3 days+ out of the same phone, either they didnt use the phone much or left it in standby through the whole time.

Post screenshot from Partial Wakelocks and Alarm (if you have enable root feature on BetterBatteryStats). We can find more information about apps which wakeup your phone all the time.
If I say I have to use 2 or 3 batteries per day, will that make you feel better?
Don't bother it, if you can have your screen on time over 3 or 4 hours, you can be happy with that, because from my experience, that is how our S III can do, of course with some more tweak and caution on the battery you can up it to like 5 , 6 hours.
If you really care about it,, like what? Lower CPU, undervoltage it, even the GPU, screen brightness down to minimum, kill all non essential function like BT, Wi-Fi, data connection, GPS... etc
Just don't compare with people around here , they are just like geeks over here...

So you are saying the posted media server fix does not work .
If GP music is always running somehow you have turned it on .
Battery is variable depends upon usage and a key often overlooked component is your network and the masts . Weaker the signals the more time the battery drains searching signals .

yea it seems the posted mediaserver fix dont work, and GPM running seems to be a common problem with the latest update .. i have just froze it .. we shall see if it has any significant impact.
also, my signal strength is always high, so no issue there.
somehow i was unable to find GPM in greenify so had to use Ti to freeze it
Hi everyone!
Some days ago I bought a new battery for my S3 (seller said to be genuine) and I am disappointed because its performance is almost the same as the one I was experiencing with my old battery (18 month-old battery). For this reason, I have been researching and I have done this until now:
*) Being honest, this comparison is somehow subjective since apart from the battery change, my S3 was officially updated from 4.1 to 4.3 almost at the same time I changed the battery. Then, I wonder whether this update may have affected my diagnosis on the battery duration.
1) According to the point * I decided to do a battery calibration "without root" consisting in draining the battery to 0% and charging until 100%. I haven't seen any improvement doing this.
2) As consequence I analyzed wakelocks. I have addressed two of them from the System:
- AudioOutLock. to fix this one I did as recommended: disabling sounds when typing and all of this.
- Backup. Fixed by disabling the backup from Google (I would like to have it enabled but if it is causing a battery drain...)
3) I let the phone the whole night turned on with the 3g connection on and I got a ratio of 2%/hour draining. I have read this is more or less under the normal parameters.
After doing all of this I'm still not happy with the performance. Usually, my mobile gets under 20% by the end of the day with the screen on in a range between 1h30m and 2h. If I remember well at the very begging (when I bought my phone), I was getting my phone at 20% by the end of the day but having the screen on for 4h or more. After buying a new battery, I was expecting to return to that situation.
Do you have any hint? As for example a better way to calibrate? Factory reset may help? Should I check a specific wakelock?
Thank you very much in advance!
I forgot to mention that when I let it charging over night, my s3 does not always charge until 100. Sometimes it's until 98 or 95. I don't know if this helps you guys as a hint but I want to provide as much information as possible.
Thanks

Thanks!, I will check. But so far I have briefly seen it looks like there is not a specific solution more than disabling gNow and some other things. Maybe a good option is to downgrade or using a custom rom in which there aren't these problem.
its same to me.

Thanks!. I have been using Wakelock detector but I will try with this one. I was wondering if using this kind of applications for checking the wakelocks may provoke some battery drain itself. I mean, should it be used just for analyzing when you experience a battery issue? or should they be permanently installed no matter whether you have battery problems or not?

Hi, Better Battery Stats is using an already existing process of Android to obtain it's information, therefore the influence of the app itself on battery drain should be negligable.

Thanks for the info!. I have not seen anything special in the partial wakelocks. In the kernel wakelocks, it is difficult to distinguish whether one entry is specially problematic or not. After what I have read so far it may be the mix of social apps I have now installed:
- Whatsapp
- Twitter
- Messenger (FB messenger)
- Line
I guess maybe I have too many of them reason why the battery is draining more than normally when the screen is off

sometimes changing kernel could solve the problem..boeffla is the one i am satisfied with..and agni kernel is also one of the better kernels..:good:

Sorry for the delay to answer, I've been busy. Here I post the images of the battery stats. Sorry, they are not what you told me to be having them 5 hours quiet (that's difficult for me). However I can tell you that the 40minutes of screen on where just chatting on whatsapp or checking emails; no angry birds or need for speeds hehe... Are these images ok to be posted on the thread you told me? Thanks in advance!
I had a poor battery perfomance after upgrading from 4.1.2 to 4.3 until I've disabled fast dormancy. It seems that in v4.3 is enabled, and if your carrier doesn't support it, it will eat your battery. Donwload free from market "fast dormancy togle" by Siyah, and that's it

I have just rooted the phone and disable the fd. I hope this works!. Thank you very much for the info. However, now that I have it rooted, do you suggest to install a custom rom for getting a better performance? if so, which? there is a good one with 4.4 and multi-view?.
Thanks in advance!
Try flashing allblacksback mod it makes the whole system dark and saves battery on display and also I recommend disabling Google play services but this means there will be no push services but it saves a lot of ? ? ? ?

After giving a try to the idea of disconnecting the fast dormancy here I give you some reports on the battery consumption. I don't know why but statistics are wrong from the point of view of the duration (3 days).. since I disconnected it just 10 hours ago. I think its consumption is still huge. I hope you can give me a hint on it. Thanks!
Ive installed smartdroid. Battery perfomance seems quite better now! What do you think from the screens? However.. i find the screen too much consuming.... ive seen people managing 5 hours of screen in a day. Why i am not? May it be battery or configuration?
Thanks!
Do you have any hint on this? Ive seen that with the screen off the consumption is really good. However, with the screen on a doing normal stuff: chroming, feedlying or whatsapping it goes to a 20-25%/h.
at first: this is not a "whats the best rom" thread.
i have 2 very focused questions:
What are the idle times with those different roms?
Are there some Main feature differences?
Aktually im running cm11 m5 snapshot with smartassv2 Governor. its smooth but the battery life is kinda poor.
Im looking for a rom with long battery life. And i dont care about google now, talking to my phone(ok google) nor i need the special features from the standart samsung rom.
Would be realy helpfull if u can review to my questions. Greetings!
pls apologize my bad english.
1 each phone is different depending on what's installed and running.
2 read there threads or flash each ROM and find out that way. You forgot about aokp?

There are no definitive results, I have used both and I keep coming back to Omni due to the fact that on SlimKat music stutters like crazy when the screen is locked. Also, Omni updates are small enough to update often without having to download a complete update, to many users this a huge deal due to data limitations in certain countries. As for usage, idle time etc, like stated before, that depends entirely on what is installed on your device. Install a bunch of apps that need to constantly receive data updates and you will have battery drain and very little deep sleep. Where features are concerned, you kinda learn to live with limitations due to missing features on a specific rom. If you really want, you can most likely find an app that will bring a missing feature to a rom. I see a lot of people throwing their toys out the cot because one of the other does not have a specific feature implimented, yet the developers have done so with good reason, usually either performance or battery life.
With all said, there are many roms out there, Omni and SlimKat aren't the only players. It's difficult to compare roms nowadays because you are never quite sure if your kernel tweaking or custom kernel with it's hundreds of tweaks is the reason for a device not going into deep sleep either.
Give them all a try and decide for yourself, nandroid backups and apps like Titanium Backup makes it so easy.

im missing only 1 thing. if someone flashes all roms, doesnt install any apps. Only new rom and full wipe before, restart and tracks the time the phone has battery. Dont u think this is a possibility to compare the roms battery usage? i think there is no one who does this, but i probably will try this and put down a little table here. so people like me are able to see the rom with the best battery efficiency. so if they decide this rom has not enough performance, they can switch to "battery efficiency Number 2" and so on.
greetings

Sure you can do what you stated but bear in mind how will you compare the battery life across roms..
There should be some standardized test... Like looping video playback or some other method which does not change based on you usage habits..

Pa is another you're missing from you're list of developed roms. What you could do is test video playback, calls incoming/outgoing,one game of choice "high end battery draining game" and compere them all. As for the kernel tuning.. Read about what really happens and you will fine not a lot does happen with UV/uc .

You can compare but you have to use that phone for more days not like just one and you have to full charge and then discharge 2 or 3 times till the phone make the correct battery stats. So i think you can test but better with daily use or get an app that drains battey faster well i think this may work
