Hi guys,
I'm losing my patience with my S2. I can't put a finger when this started but ive noticed that the screen is taking up an awful lot of battery. Today for example I have taken it off charge 8hours ago and it's down to 14% despite not using it for much (except texts and internet a few times). When I check the battery monitor on settings it says that the screen has used 70% after being on for 1hr 17m, phone idle is 2nd with only 11%. I'm using the Resurrection Remix rom but I only loaded this after the problems started in an attempt to try and fix it.
I've uploaded some screenshots, theirs a sharp drop in the battery as the phone crashed and it seemed to of took a while to find out to charge again. Also Betterbattery only had data up to the point when it rebooted itself.
Thats totally normal.
Im not using Resurrection remix rom so i cannot comment on that,
but my screen is always 60%+.
The only solution is to lower the brightness, and turn off the Touch lights.
Really? It just seems like its using a lot of battery. The brightness is already very low (20-25%).
Seems like how long the battery lasts vary from phone to phone though by the looks of the forum. 15 hours doesn't seem too bad compared to what some people on here are getting anyway.
Mine is using 85%

85% after having used it for 13 minutes? If you want to talk about your screen consuming battery atleast let it run down to around 15-20% before commenting. And it depends on how you use the phone as well. And I dont mean merely in term of screen brightness. If you spend most of the time browsing the web, sending texts, watching videos,etc its pretty much a given your screen will be the highest battery consumer. Try spending most of the time talking on the phone and you will see a difference in the proportion of battery the screen consumes.
Also, the screen is the single biggest I/O interface for any touchscreen device. If that doesnt consume maximum battery, what else will? 60-70% battery consumed by the screen is pretty much the norm, mate

Thanks for the info sir...If I may ask OT if I set my phone to no background processes. Will it also disable the ability of my phone to receive call or txt messages? Thanks for the reply sir.
The phone's battery indicator will take the amount of time the phone has been off the charger and then calculate the amount of time the screen has been on.
For example if the phone has been off the charger 20 minutes and the screen has been on for 15 minutes of those 20 minutes:
15/20 = 0.75
0.75*100 (get to percentage) = 75% screen time
Cheers for the replies. I've just tried turning off sync today and my battery has seriously improved so I'm guessing it's something like Facebook etc that is causing problems with the battery. Nothing seems noticeable on bettebattery app but to be fair I struggle to understand half the stuff the stats talk about.

Yeah..syncing apps tend to drain the battery a lot with wakelocks. EDIT:for apps like your email, switching off the auto-sync option and instead sync on demand helps as the phone doesn't then have to periodically keep waking up and checking for new mails.
Google apps like latitude are another notorious cause of wake locks and eventually battery consumption. If you can do without location services, it'll help with your battery life.
Sent from my GT-I9100 using xda app-developers app
No offence, but syncing email takes very little battery, especially with the stock email apps.
Syncing such things as Facebook and news apps will cause some battery drain.
Also when flashing new ROMs, it's recommended that you backup anything you need and wipe the SD memories. There can be differences in ROMs and the way things are structured and can cause drain.

Actually I was curious about the SD card as well. I've not wiped the card or the internal memory since I got the phone and its become a bit of a mess. Is it alright to format both of them without causing problems except for the apps which use them?

Well wiping the external SD Card means you will lose your music, photos, videos and any apps saved to it. Connect it you your computer and then back it up. As for internal, not too sure what you will lose. Not too sure why you would wipe them, screen time isn't caused by them. If your battery is draining quickly, download BetterBatteryStats and see if something is causing a kernel wakelock.
Sent from my GT-I9100 using xda app-developers app
To wipe, use the factory reset (you will have to install your apps again, unless they are backup up by Google, check settibgs) and identify which locations your external and internal sd are, format just those 2 but don't format system!
This has nothing to do with screen time etc but may help the battery drain. It's only a possibility and one which you can try if you like.

My battery consumption by the screen using RR 3.0.6 with DorminManx kernel 5.80 its 62%.
Don't worry
Change rom
Dude, I had the same problem when i switched to different roms, I have found that AOKP and CM9 roms with STOCK kernel are far better than any other roms with siyah kernel, no matter what you change in siyah kernel (undervolt, governors...setcpu etc) they will never be as good as CM9, trust me.
I got bored of changing back to cm9 always, its really the best stock rom.

I have tried everything. I tried various ROM's, SpeedMod kernels T27, T29, T32, and T39, and the stock ROM, and NOTHING is working! I cleared out my Dalvik and cache partitions obviously, and I caliberated the battery. Nothing is working!
I used the phone for 8 hours today, and the battery dropped to 50% in those 8 hours. I had the display on for 1 hour and 30 minutes, browsing Tapatalk and the internet. I made no phone calls at all. Besides that I listened to music for 45 minutes, but that's it. The rest of the time it was on standby in my pocket. This is running Lite'ning ROM v6.1 and Speedmod Kernal T39. However, no matter what combination of kernels and roms I try, the drain is pretty similar.
I have the stock android weather and news app set to update every 3 hours, and K9 Mail to fetch new mail every 15 minutes.
This is with Wi-Fi off, GPS off, and bluetooth off.
What could be affecting my battery so much? Is there any information I should post here from my phone so you guys could see what is causing this? I can't even use my phone for one day without the battery completely draining.
Well, you problaby already knew this, but the real life-sucker in the SGS II is definately it's screen. Get the brightness down low and make the screen timeout after 15 seconds so that you don't waste any unecessarily battery.
Can't help to much otherwise, just got my SGS II a week ago, still getting to know it myself. But hope that helps abit anyway.
There may be other apps synching in background. In my case fluent news trend to hang around. Check if every app is doing background work.

I can assure you mine is worse, drops to 50% in 6-7 hours, but as the other person has stated, the screen is the culprit, when I used the phone longer than you, I would expect worse battery life.
Gosh how I wish this phone was equipped with more energy-efficient, less bling bling screen. SAMOLED+ is only good for show-off, which I usually don't do.
Theres an app called betterbatterystats on the xda forum. Use that and see whats draining your battery, especially in the wakeloks department.
Updated Facebook? It's raping batteries so hard it should be on the 6 o'clock news tomorrow night. Or, you know, pretty much anything these guys say here.
Try to use Betterbatterystats and see partial wakelocks and cpu spy to see if you have any problem with deep sleep! Also take a look to battery usage and the percentage of Operating System Android

i definitely agree with this. i unticked the auto adjust brightness, and i set the screen brightness to the lowest value at all times (it's super amoled anyway, the screen is still visible even at the lowest settings).

Make sure you sign out of facebook chat. I had a funny feeling that the chat was keeping my phone awake. Turned the chat off and I have had excellent battery life since.

First of all I think you are wrong when you say OLED uses more power than LCD. Remember how these screens work, LCD lets light go through and is completely back-lit all the time while OLED screens emit light from pixels that are not black.
On the other hand, the real problem with SGS2, in my opinion, is the reason phone never goes to sleep. If you take a look at screenshot I attached you'll see that screen on my phone was not on all the time but battery drain continued. Also, "awake" bar is full meaning phone never got the chance to go to sleep.
I have no clue how to fix this, maybe someone with more experience can help. I use to have HTC Hero on which I could turn off "Always on" in network settings and get phone to sleep often and save battery that way.

If you ever accidentally go into chat again it will log you back in. Just remember to always log out again. Do not use the back/cancel to get out of the chat screen.

Display drain about 1% every 4 minutes of browsing, this is in your case 22,5% .
Every 15 min email checking and the automatic update checking from other apps does the rest. There is nothing suspicious with your battery drain.

Bad apps?
I've had bad battery drain for the last week.
I've rooted, romed, unrooted, changed every setting I could. Nothing has really worked. I'm was losing between 5-10% an hour.
Then I just wiped everything and re-installed the stock 2.3.3 firmware and started re-installing apps an hour at a time.
Battery burn was going good about 1% an hour installing about 5 apps in an hour until I installed TM World Clock.
Within an hour I had a 10% battery decrease and Watchdog saying that Event/0 and Suspend were consuming the 90% of the CPU. I uninstalled...it went back to a 1% and hour battery drain for 3 hours.
Re-installed TW World Clock to see it was a fluke. Within 10 min. the phone dropped 2%. and Watchdog started sending warnings for Event/0 and Suspend again.
There might be certain apps that aren't allowing the Galaxy S2 to go into a deep sleep...explaining why the problem is so random among different owners pending on installed apps.
Ok so im quite new to android so im not 100% on the ins and outs on how what uses what battery and when.
Im running skyrom v9 and my battery was crap. To be honest its never been good. So i tried speedmod kernel and still got the same results.
Now iv disabled lockscreen widget and seems my battery is much better so iv put it down to that been the killer.
Iv read some people are using this app with no issues. My friend tried it with the same rom and kernel as me and it was fine.
Question is are these phones like performance independent? Like will each device act and behave differently to different thing or shud one sgs2 be the same as another sgs2 that is set up the same?
Long winded but i got there
Sent from my GT-I9100 using XDA Premium App
They're mass produced, they should be exactly the same. There may be really really slight performance differences. And tiny differences in screen quality. But this may depend on the batch.
What would be the case most likely would be the fact that you have a faulty battery. But it seems you were able to fix most of your problems by getting rid of an app.
There's a lot of things influencing battery life, dude! Every little thing you do and use can get the juice sucked dry in a couple of hours.
I thought as much. Just seemed odd. And although getting rid of that app seemed to work, its now gone back to its useual gonna die soon self. Gonna try another battery i think.

In a way they are all different .
Different users with different apps and settings plus a different and varied level of user intelligence . That means phone A can be poor for user ZZ but give it to user YY and its working well .

Well only thing i have left to try is battery. Im just waiting for my other to charge then i will swap and test it. Best i have had my battery is loosing 10% an hour. Which imo is a bad crack.

A good test is to stick it in flight mode and shut down as many apps as you possibly can. Then just leave it in standby for a couple of hours. You should really only lose 1-2% of your battery. If you do then you know something on the phone is responsible and you can start looking for and freezing the suspects.
I've had mine in standby for about 9 hours now (since I unplugged it) and it's at 91%, after only a few texts and emails. That's with data on most of the time and a little wifi earlier. I'm on 2.3.5 and KH3.

The phone is the same, it really is all in the user settings and usage styles. If you want to prove this, just reflash any ROM and kernel (they are not that different) and do a full wipe of the phone. Don't set up a Google account or any email accounts or install any launchers/apps/widgets. Use a plain black background/lockscreen. Just use the phone, SMS and other stock apps for a while. You should be getting around 3 days or more of battery life with moderate usage.
I've gotten 3+ days of battery life before, but nowadays I get less than 1 day. So when I read that other people are getting great battery life, it's not because their phone is different than mine. It's because I need to use Exchange for my office email, or because I want to run a certain widget, or have some extra notifications, etc. So all you can do is keep experimenting, updating, etc. until you find a combination that works well for you.
I've seen a lot of users' postings of battery statistics (screen shots) and they are all considerably better than what I am getting. The biggest difference I see is in the amount of battery drain from "Android System." What I see posted is between 9% and 13%. However, my batt stats show the Android System draining 60% of the battery.
So, what am I doing wrong? I'm still kind of new to Android. Is it the widgets? I've checked running processes verses what apps are draining battery life and nothing is running that drains like the system does.
Further info: I am currently running the 7.18.12 build of Diet ICS, but I was seeing this behavior on stock as well. Some widgets I use: Astrid premium tasks widget, Evernote, doubletwist, slacker, 3D clock/weather, a widgetsoid switcher, and APW Calendar.
Thanks for any help or suggestions.

How often do your widgets that gather info refresh? Try scaling down on some widgets and see if that helps. If not, try to flash stock with odin and start over. I was having some problems with my phone when I first got it (MTP specifically) and I falshed stock and everything started working fine. Also, if you are using Google Chrome, make sure you have the experimental feature of using the gyroscope for tilt scrolling set to off....it is known to drain battery.
Hope this helps :good:

Maybe I will try flashing stock if I have time today. I reset my battery stats in recovery mode when I took the phone off the charger this morning, so we'll see how today goes.
I looked into the widgets and the only one that refreshes data on a schedule is the clock/weather. I'll try a different one or just not use the weather.
Great tip about Chrome. Didn't know it did that.
Do I actually need to calibrate the battery? I tried the method of letting it die and charge back up a few times and I've tried recharging once it gets down between 70-80 percents life. I'm not sure which method helped, but I did notice an improvement.
Thanks again for the help.

Never mind! Just searched" CPU sleeper" on the Play store and--voila!
On another note, I'm so glad I got a device with a huge support community. Coming from iOS, it's nice to feel part of a collective effort again and get such great advice. I know there are a lot of iOS forums and there is some great work done through those communities, but those seem so trivial compared to what is done through XDA and the level of helpfulness is unparalleled here.

I read somewhere in the forum that these batteries actually like to be constantly charged up and not let die completely. There was no explanation for this but I will research it because I am curious. With my old Captivate, i let it die then fully charge to extend the overall life of the battery.
How is your battery so far?

Further info: I am currently running the 7.18.12 build of Diet ICS, but I was seeing this behavior on stock as well. Some widgets I use: Astrid premium tasks widget, Evernote, doubletwist, slacker, 3D clock/weather, a widgetsoid switcher, and APW Calendar.
Thanks for any help or suggestions.

Have you tried using the CPU Sleeper app?
http://forum.xda-developers.com/showthread.php?t=1745516
I found that it does a great job of preserving battery life when the phone is in standby. I used to notice my battery draining really fast over short periods on standby (phone would be hot to the touch). After installing this, I have not encountered that problem again. I get 16-20 hours of use on moderate usage. LTE, gps, and sync are always enabled. I DO NOT have the phone in power saving mode and I seldom use wifi. I used to get 10-12 hours of battery life on the same usage before. I am running the rooted version of the stock rom from my carrier.
CPU sleeper app works great for me. I am in a non LTE area but get incredible battery life, last all day usually with around 50% left. An order of magnitude better than my SGS2

I am using CPU Sleeper now, thanks to the advice of a previous poster on page 1. Good to hear it works for others.
I had the SGS2 as well and the S3 is definitely better.

Hi all,
I also notice this and this were the steps that I did and seems to help me to reduce this process to like 5 %. I'm on Sprint S3 but should be the same for the all carriers.
Go ahead and open Talk application. You should see your account in green (I'm not using this application) then hit the menu and then select sigh Off. Make sure that your account changes to Offline (sometimes it is change back it self so open one more time make sure that it says Offline). Then what else I change is in wi-fi advanced options: under Keep Wi-Fi on during sleep I choose Only when plugged in option. then I reboot the phone and from now on (almost 2 days) my Android system process show up only 5% of usage and my battery life improve significantly. I hope this will helps.
Thanks
Those are great tips. Thanks. I will say I've gotten increasingly better life since employing other tips discussed here.
Something else I did was download a profile changing app. I got Quick Profiles, but anything should do. If anyone uses anything better, please share. I have a profile for power saving that turns down my brightness, and turns off wifi and Bluetooth. The app will let you put shortcuts on the home screen to instantly change the profile. I'd like to find one, however, that will also turn off gps and mobile data.
Can somebody help. My sgs3 battery seem to drain like a loose drain. I charge 100% at 12.30am and go to sleep but by 5am battery is completely drained and phone is dead off. This is not the same during the day. Are there processes running when the phone is Idle that brings about this massive drain. Please I need help asap.

Do you leave many programs running, alot of frequent sync going on? Did you leave Bluetooth on or something that you don't need during night? Just guessing...

Search battery drain on Google for this device....lots of results,b but it generally comes down to learning how to use your phone and it's features, and when and what stuff to turn off etc etc
I don't leave anything on. I ensure I disable prefetch on my YouTube, disable auto updated on dropbox, I don't use SNS, and off course screen time out after 10 sec.

how can i fix the multipdp problem?
Thankz for help^^
There is obviously a problem if it's dying in <5 hrs.
Did you recently connect to Kies because I was having probs with my SGS2 getting really hot and losing power as a result of Kies/a dodgy USB lead?
A factory reset solved it however ( remember to back up ) but sometimes just removing your battery for 90 seconds to reset the values works.
Good luck.

The last thing I remember dong was hotspot and I made sure I switched off everything. From the posts above I tried the cell_standby fix and it still did not fix.

Turn off Google backup, face awake, try that for starters
First of all, switch off your phone for a while to see if there is problem in battery or its the apps you are running. If you think it is a stupid step,
Then try using some software like JuiceDefender or something.
In app manager, kill apps that are useless.
Also turn off features like bluetooth, gps etc. if on.
Reduce phone's brightness, recommended to set it to "auto".
Turn off useless vibrations and LED notifications.
You should now see significant improvemance in battery life.
Hope this helps
I have taken all these steps gone ahead to remove live wall paper, auto sync disabled, brightness is set at auto. And its still the same. I don't want to tow the line of hard reset because am not sure that would solve the problem coupled with the time it would take to get my sgs3 to suite me

I use juice defender which manages everything for me, an overnight schedule ensures the battery only drops by 1 or 2%

okay so i thought i had a battery problem before i tried putting my phone aside (meaning no games, no internet browsing and no video streaming nothing, just using whatsapp and leaving facebook connected. I also have lots of apps and games installed over 15 or something)
If you decreasing screen time you will notice a HUGE difference (24hrs in my case), its basically down to usage, I have tried over 10 different roms and kernels as well as the v6 supercharger script, i dont ever notice the difference, EVER. unless of course i use a minimalistic rom with almost nothing to play around with, but if thats how u like it then go for that. Id say following all the fundamental steps will take you a long way
my final advice:
less screen time
when on the screen use the least brightness available
decrease stock brightness even more if you can
less app usage
if your not one to constantly play with your phone and customize stuff on it try installing a minimal rom like
|ROM|XXBLG8| IOIDroid Super Slim Edition | Buttery Smooth | V1.0.0 LIVE !! |
or
[ROM][4.0.4] Slim ICS (SGS3) - Clean, Simple & Fast (63MB)
i dont know if this is a placebo of not, but sometimes i notice improvements when i undervolt, underclock and limit to only dual core. believe it or not sometimes it has little or the adverse effect of saving battery
good luck man
And another question, which can be solved through the search function or Google -.-

So here is my experience. Have been using android for years, have had an hd2 so I know how to get good battery life results. For some reason I easily lost 15-20% overnight with just the gsm 2g radio on. No matter what I did it drained fast even though deep sleep was fine, all extras sync and etc were off. 3hrs screen on time in 14 hours and it was dead.
I kept waiting for an update to solve this and it never came even though I was force checking it.
I ended up factory resetting the phone and as soon as it booted up an ota update popped up. Since then I am having nearly 6hrs screen on time in 40hrs,which is amazing.

I will try the juice defender route and hope that it solves my problem or else I will be forced to tow the hard reset route.

Greetings, I have seen a similar problem back in our hox forums. I have come here in peace to help, though. Recently, someone suggested bump charging, it's like a natural way of making your battery recalibrate itself without wiping battery stats or stuff like that.
First off, charge the battery until it says 100% while the device is on.
Then remove the charger, turn off the power, and charge again.
Remove the charger again when it says full while the device is off.
Turn it on again, then when it's properly booted, charge again, but don't use the device until it says it's fully charged already.
Mind you, we're not sure if it's just a placebo or not. Some claims to have had better battery life after doing this for once a month. I haven't tried it yet, but I thought I could share it here too.

I saw this method being used with good results (reportedly) on my SGS2 so it's definitely worth a bash if you can't be arsed to reset.

Just to offer two cents from my experience with this phone.
I recently got a replacement for my s3.. the details of that are for another post, but this relates to battery:
when I first got the phone i started using it right away. I did not charge the battery until I got to the office and charged the phone while using it the first day.
when I got the second replacement phone I already had a second battery.
This battery was fully charged and immediately used that in the new phone. fully charged the samsung battery before I used it.
I noticed significantly better performance with the second phone. I think it was because of the way i treated the battery strait out of the box.
any one agree, or have a similar experience?

Do you have an Exchange account set up?
After the newest update i also notice that it has a high % drain even if i turn 3g off, gps and everything nothing unusual runs in the background that can explain high drain yet it does.. and i didnt notice that before the latest update and i havent installed any weird apps. I also have all my weather and news on manual update so i dont get what can drain the battery with internet off overnight.. its frustrating a bit.
After doing a complete wipe install of mean bean, my battery is still draining about 2%/minute. Now, I realize there is more than likely some other issue, that installing mean bean uncovered or removed the block before.
Questions;
1) is it normal for the screen to be using 60% of the battery power?
2) Is there actually an app that controls the battery usage, and truly kills apps?
- I have tested several, with no noticeable difference in power usage.
Thanks for any advice, for a somewhat novice rooter.
yup
The 60 normal if screens been on a lot. The 2% deal sounds whacked. Have u gone into settings/apps/running to see whats running?
Fixed, I think

I'm not sure what I changed, I limited the processes to only 4 running, that might have helped. The battery still drains faster than before when the screen is on, but not as it was before. I am giving "Easy Battery Saver" a try see if that tells me anything useful, it at least keeps the settings that are applied. With any luck it will keep working until I break it again, lol.

I was having bad drain issues and read some post about location tracking with Google maps. I disabled that and my battery life on MB 3.09 is back to normal which is great.
Funny thing is this happened seemly out of no where but I think there was a recent update to maps. My location tracking has always been on and never seemed to affect battery life before. Go figure.
