I am having huge issues with my battery on my galaxy s2. It drains really fast, 60% over the last 15 hours this night when the phone has been idle. This has been an issue for about a week now; I cannot seem to find a solution? I have tried various roms, wiping and doing a clean install, but the problem continues. Currently using lightening rom 3,2.
Do anyone know what can be causing this battery drain? Is the battery defective??
What apps do you have installed?

That is quite a drain I can see there. The drain might be caused by having too many widgets or having too many applications open. If you plan to put it on standby, do close those apps that are not important to you.
Have you tried rebooting?
I have a stock lightening rom 3,2. no apps installed, except titanium backup pro and opera mobile. I have frozen all kinds of stuff in titanium to try find the cultprit, but without success. As you see, no apps except andoid OS is running. Same drain on villainrom, lightening. Don't know what can be causing the error. Is there some way to check if the phone or the battery it self is to blame?
Try with screen on - normally I think that should run for 6 hours or so. Using that as a reference, you can check to see if the energy stored in the battery is normal. It doesn't look like your OS is staying overly active to me.
Hi bjorninge,
Every time after you flash a new ROM you should calibrate your battery.
Get the app "battery calibration" from the market and follow instructions and please report back whether you can achieve better performance.

I have a similar issue, as was the same with my captivate. I have stock ROM on my GS2 though, the way I got it out of the box pretty much. Android OS takes up most of the battery usage. I don't know what it is. Widgets updating constantly? The constant syncing from Gmail/push email?
Well that's surprising! Awake and Screen On bar is quite low and totally synchronized, yet 60% drain, now I gotta say it's weird.

Unfortunately, I have the same issue as you've described above. I am running on stock KE2 kernel and the battery drain is quite a lot. The 'Android OS' is always consuming a lot of processor time on standby mode.
This needs to be fixed A.S.A.P.!
Download and install the app BetterBatteryStats from Android section, it is a very useful app which will show what Awaking the device from deep sleep and processes too. For me, it was the damn Latitude stuff going on background and wasn't letting the device to go to deep sleep.

Thanks for the tip. I have downloaded the app now. what spesifically should I look for?
You just look under 'Wakelocks' and you will know what apps are causing the Awake, then you could take further steps.
Regards.
Would be great if you could look at the screenshot and tell me if something is wrong. Also, after the battery calibration, I've "only" lost 26% the last 7 hours mostly idling. I don't see anything abnormal in the screenshot I provided :/
Well nothing is wrong imo as everything is very low. You should check those which are using more than 10 mins Wakelock, some seconds doesn't matter actually. And you can post any query further to the original thread of this app, here,

Regards.
OK, So I'm now back to 12% battery usage (from 100% to 88%) with 17 hours and 30 mins on battery, which IMO is normal.
What did I do? Well, I removed the battery and put the rest of the phone into the stove for an hour on 50-60 degreed celsius. My 98% android OS usage is gone and the battery works as normal .I also had problems with the phone constantly going into "car mode" which is now gone.
I got some tips around the internet that my issues were all related to moisture on the inside of the phone.
Hi all,
I love the Sony Tablet except its battery life. for something that is so huge compared to the others similar products out there, I am sure that they could have squeezed a bigger battery into the unit.
The power capacity is pretty weak. Let's hope that Sony offers a higher capacity battery size. I would gladly pay to upgrade it.
That's weird, my battery life is fantastic. If I play games on it all day it'll last 8-12 hours, but if I just use it intermittently and moderately it'll easily last me a couple of days. On standby it only uses a couple percent a day if that!
I'm the same as unclespoon. Even during heavy use, I get about 9 hours, which is way better than my old Galaxy Tab could ever muster. Standby usage is crazy low, its fantastic!
Not sure what you mean either about being larger than most other devices. The Tablet's 9.4" screen is smaller than almost any other full-size Tab out there (including the iPad) and since the back curves, theres not actually a lot of usable rear space (look at how thin its getting at the thin end, now imagine trying to fit a battery in there!)
I'm not sure you'll find a Tab out there currently with a better combo of size/battery life. The chunkier Toshiba Thrive will last longer, the thinner Galaxy Tab's will last even less, and my Tablet S always outlasts my iPad, so it might just be your device. Try checking Settings -> About -> Battery Use
I'm of the same opinion as the op. My tablet s has dreadful battery life and especially when it isn't doing anything. (50% usage is system standby) my old galaxy 7 was far far better (charged about once a week)
I believe this may just be because it is new (only have 1 full charge) as my galaxy s2 was initially unimpressive and then lasted 3 days of moderate use without charge. Hoping the same will happen to my s1.
Time will tell
My only guess was that you did a shoddy job of conditioning the battery. My old Galaxy Tab (the first 7" one) was hopeless, but when I replaced it, I conditioned the battery better and it was a bit better.
My Tablet S lasts for days and days and the standby usage is tiny. Check whats using your battery in the Battery Use screen and get back to us, we might be able to help..
I noticed advanced wifi lock was causing massive amounts of wakelocks (8 hours out of 10 according to the stats in settings/about).
betterbatterystats is not available via market but I am trying out the XDA APK now

I noticed that as well. If you have Advanced WiFi lock activated the tablet won't go into deep sleep mode, there of massive battery usage. I still have Advanced WiFi lock on my tablet, but only activate it when I need to download/update something that takes time. Otherwise I turn it off. It's not worth the battry drain.
Wow. Your battery life are fantastic. 9 hours? That's huge. I have not used my Sony Tablet till flat but given the rate of battery loss think maybe the most is about 5 hours which is similar to what many reviewers are saying.
Just can't imagine that those reviewers are so far out of the ball park compared to you guys. I am using juice defender Beta. Not to sure if its helping or not. But at least if I not using WiFi it shuts it off automatically.
My battery used to drain badly during standby. I found that the Friend Stream service was preventing the tab from sleeping. Killed the service a while ago and battery has been fantastic since. Pushed it to 3 days with light use. About 3 hrs of browsing and facebook. My battery level is at 68%, been off power for 20h40 mins, and used for about 4hrs today - facebooking, Internet browsing. Note that no specific conditioning was performed.
What are the settings that you have on your Tablet? Auto brightness, background sync turned off ?
how did you stop friendstream, and what the heck is it, did you just kill the process and it stayed dead? (sometimes as u know u kill process but it will come back).
Good question. What is the Android software revision now. My is Android 3.2.1 (revision 2)
I acutally just uninstalled the crap-app. nothing I use anyway. It is an app for facebook, twitter and other social networks. So just get rid of it. Uninstall and be happy
my bad. I confused the HTC name and Sony name.
Social Feed Reader was misbehaving. Once started it kept running... rather than dropping off to sleep (and into Cached Apps).
Something wasn't right so I force stopped it and it stayed dead.
An additional note - the Setup, Applications, Running Applications feature isn't 100%. Some background apps aren't displaying as running or Cached. Go figure.
So any special method to stop the social feed reader?
I'm getting those kinds of numbers on mostly auto brightness (and sometimes lower, at night), with background sync turned on, WiFi sleep policy set to default, and no battery monitoring or saving apps running. The only thing I did was single initial conditioning cycle and since then its been great.
Also note that software-decoded video files will take a lot more of your battery than the equivalent properly encoded file. I havent had any trouble with Social Feed Reader, but I never even set it up and judging by the many stories around here, I would uninstall it if you're worried about battery..

Hi, that's good to know. Thanks for sharing. Unfortunately think I screwed up the initial conditioning. so I guess I will have to live with the 5 hour battery of my Tablet.
Btw how do you do battery conditioning?

In Setup, Applications, Running Services have a look at the awake time (listed on the right side) of the running processes. You'll note that system processes (the ones with the Android icon) have been awake since last boot.... but you might finds others that are as well. I noted Social Feed Reader showing high awake time and decided to nuke it. Simply click the offending app. You'll be given the option to stop the app... which is what I did. It's an app so doesn't restart once killed. Hope that helps...
Final thought: at the top right of the screen there's a 'Show cached processes' option.
The could be an offending app in there. Kill any installed app you suspect might be a problem and see if that helps.
my battery life is excellent.

Hi everyone
So I recently got a S2, upgraded it from stock Gingerbread to stock ICS via Kies, then flashed CM9. CM9 was great, but I quickly noticed worse battery drain than that of GB. I sorted out all wakelocks, now facebook is the top one in better battery stats list and it's only 10mins in a day so I don't think that's a problem. When charging, vbus_present shows up and keeps the phone from sleeping, but that's a normal thing when the phone is plugged, right? CPUspy shows the phone is in deep sleep the majority of time I don't use it, so I assume I have no wakelock problem.
But even then, the battery still seems a bit bad. When in deep sleep with wifi and mobile data off, it would lose around 1.5% per hour; and with moderate/high use (internet with wifi or gaming), I'd be lucky to have it last 3 hours. Charging to 100% from zero takes about 3 hours.
I also tried recalibrating the battery through BC, but haven't noticed too much of a difference.
Recently I found a guide on disabling fast dormancy via the build.prop file. Still waiting for results though.
So, my questions
1, My battery usage seems normal, doesn't it? 1.5% per deep sleep hour is acceptable I guess, but 3 hours of usage seems a bit short. Too short.
2, What effects does fast dormancy have?
1) Totally unacceptable. Mine lasts at least 7-8 hours with high use..
Does your phone heat up while the heavy use ???
What brightness level do you use for the display ???
How many apps do you have that can gain internet access ???
2) By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.
Luckily, Fast Dormancy can be disabled on the phone. For the Galaxy S II, do the following:
Dial *#9900#
Press “Disable Fast Dormancy“
Press “Exit“.
Easy as that!
Thanks for the suggestion I have brightness manual and at around 20%. Wifi is disabled when not used, and mobile data is always turned off unless I need it, so basically apps only get internet access when I want them to. I have also disabled sync for both google and facebook, but fb still pushes notifications to me while it's connected. Is that a major battery drain, and if yes, how to disable it?
Anyways, facebook, instagram, youtube are the only apps than can access the internet. No messengers or anything that may keep a wakelock.
My phone doesn't heat up during normal use, maybe a bit when I do some gaming (Max Payne?)
Also, *#9900# doesn't do anything on my phone. It doesn't bring up a menu or anything like that.
Bump. Guys?

Install BetterBatteryStats (search for it on here/Google Play), might help you nail what's causing the drain.
Yes I did, as said in my original post. After a night the highest wakelock are just around 10 minutes, and that one was facebook. Uninstalling it however had no effect.
Delivered using Nyan Cat's rainbow powers.
Thinking logically, there's got to be something else in those stats (partial wakelocks in particular) that's causing that drain. There's no way having fast dormancy enabled/disabled is either going to cause/fix the drain you've mentioned getting '3 hours of usage'; (I can get 5 & a bit hours screen on with CM9 & variable usage/mostly 'moderate' use) given everything else you say you've tried.
Post BBS logs here if you want someone to have a look.
Edit to add - Also post a screenshot of the 2nd screen in settings/battery, the one that has history 'details' at the top, with the 'mobile network signal' bar underneath the main battery graph.
Here you go: pastebin.com/1UwicChJ
I just registered half a day ago and don't have enough posts yet to paste links, so sorry the phone was only on battery for nearly 2 hours with some light browsing and facebook, but I hope it works.
Anyway, I looked through my running processes, and dsp manager is the only non-OS process running, besides facebook. I got CM9 so it came by default. Could dspmanager be the culprit?

It's a new phone he's got there and I doubt it could be anything battery related itself.
I'm using CM9 nightlies and I get around 9 hours moderate use. It has been said though that a lot of these CM9 builds have battery drain and heat issues.
I use Juicedefender to help with the battery life which seems to work.

About 1/3 of this time was on wifi browsing. The drop is much more drastic if I play games.
Delivered using Nyan Cat's rainbow powers.
A couple of observations. There's nothing that stands right out in the BBS log. The other one is, looking at that graph you've lost ~15% over a bit under 2 hrs. The screen has been on most of the time the phone has been awake (confirmed by the BBS log) if you look at the respective bars. You've also been using WiFi for most of the time the screen has been on/phone has been awake.
Roughly speaking, going by the screenshot, you'd get ~5hrs+/- screen on time if you kept using the phone in the same way you had during that just under 2 hrs, and this is pretty much normal. I haven't had drain issues for ages, so I double checked my details on the 2nd screen of settings/battery to make sure CM9 is reporting these details accurately (screenshot attached). Certainly in my case, this screenshot reflects what my phone had been doing for the just under 5 hrs it had been off charge/since last reboot; that is, >90% of the time in idle/deep sleep. So it probably isn't CM9 reporting these details inaccurately in your case either.
The BBS log & screenshot don't illustrate the problem you talked about in your OP. Now, if I had to take a stab in the dark at what's causing problems when you do have them (and FWIW, I do believe you're having the problems you mentioned in your OP at times), in the absence of any other info, maybe your WiFi router is constantly sending the phone packets (what's been referred to as a 'dirty router' on here before) when you're connected to WiFi & not actually using it. This scenario has been known to cause relatively high levels of drain.
So to be honest with you, based on that screenshot & the BBS log, I'm not really seeing a problem.
Now, if you want to post the same again when you actually have a problem with drain similar to what you described in your OP, happy to have a look at them. But for that ~2hrs covered by the BBS log & screenshot you posted, that's pretty much normal.

Okay, much appreciated so I guess I'll take it from your reply that 5 hours with wifi browsing isn't too bad. Seems okay, but I still find it a bit strange that (in my case) wifi browsing uses just as much battery as games do. I always thought it was a light activity!
Or maybe it wasn't the battery that had a problem, but that I set my expectations a bit too high. I came to this S2 from a BlackBerry 9700, whose battery would last half a week with very frequent use. But anyway, I just got this phone for a week, so I consider myself a pretty heavy user. Probably when I get familiar with it, I won't feel the need to play with it every five minutes and battery will last a bit longer then! xD
Nah. Anything with screen on is far from 'light activity'. Screen consumes far & away the most juice. In saying that, I've seen some people on here say they can get 8-9 hrs screen on with 2000mAh battery. How they do it I have absolutely no idea.
But if yeah, 5 hrs with the screen on most of the time whether browsing or playing games (games in particular are very CPU/GPU intensive & thus use a lot of zzzzs; unless they're really basic games like chess or similar), or anything else isn't too bad. Can you do better ? Obviously, if people say they can get 8-9 hrs. But it's not a matter of doing A, B & C and you'll magically end up with massive screen on times. Every phone is setup & used differently, and getting the absolute max out of every charge takes a lot of trial & error and experimenting with settings/setup.
There are tons of threads about the subject on here if you feel like going down that path. For me, I'm happy with the battery life I get these days because you can really obsess over it & spend a lot of time stressing over it/trying to maximise it for often very little gain. I'd rather simply use my phone a lot during the day & charge it at night.
Yeah Crackberries are like Japanese cars, they can run on fumes pretty much ;-) Having a dual core processor, a decent GPU & a huge screen kinda changes things.
There is one thing you can do fairly easily tho. And that's to make sure the phone spends as much time as possible in deep sleep when you're not using it. That will ensure that you have enough juice to get you by when you do want to use it. Simple ways to help achieve that is to turn off data/WiFi completely when you're not using it (tho many people don't like to do this for different reasons; which is perfectly OK if you're happy to live with the resultant drain), and make sure you've got no apps that are doing things they shouldn't be doing (like syncing, for example) while the phone should be sleeping. Again, there are lots of threads about same if you ever feel like a bit of light reading ;-)
So yeah, if you do find you experience drain that's not normal/outside the usual pattern you have, definitely post details & people can have a look for you. And as you said, you'll get to know what really is normal with regard to drain & so on is as you use the phone more (I tended to use it constantly for that first couple of weeks as well).

Already took such measures. Wakelocks killed my battery over my first night with the phone, and I woke up after 7 hours to find a ~50% battery completely empty. Now things are alright, I clear CPUSpy stats before I sleep and wake up to around 95% of deep sleep time. Overnight drain varies between 5 and 10%.
And yes, yes you are right. Maybe I should stop going nuts. I'm checking BBS and CPUSpy every hour, reading every XDA thread on battery, and calculating my battery drainage every morning I wake up :laugh::laugh::laugh:
Re: dirty/'noisy' WiFi networks, have a look at this post as an example of what I was talking about above.

Umm...so I just woke up, and noticed a wakelock in the kernel category. It was PowerManagerService, and it occupied around half an hour. Overnight, aftet I've slept 10 hours (got a day off ), my battery came from 24% down to 13%. That's a rate of roughly 1% per hour. Is that normal? And also, what is that PowetManagerService wakelock?

My wife and I both have the Galaxy S4, verizon flavor.
My phone's battery usage is very nice. Most of the time I go to bed with 30-70% left on the battery. Hers does the same. The only difference is I use my phone a lot and she barely uses it during the day. A couple of texts, maybe a phone call and on occasion an internet search. Before this happened, and I don't know what was the tipping point, she use to charge her phone every third day, now she charges it every night.
Her phone is also 6 months newer than mine. Both are running stock, both are Android 4.3. I have both phones setup as close as possible so I can make comparisons between the two. Obviously she has different needs and will have different apps running/installed.
I have taken all of her apps off the phone and it hasn't changed the battery problem. I have reset the phone and still the battery drain persists.
I have put Battery Monitor Widget and GSam on her phone and I really haven't been able to locate the offending app/program/function. The only possibility is the 1013 system and "AudioOut_2". But that seems unlikely as this drain is about every 20 minutes and goes on all day.
Usually she runs with her phone in minimal activity. Data off, Sync off, GPS off, Power Saving on.
Here is a chart from a while back, everyday looks similar with the drains. My phone has long periods of straight white lines when inactive, hers just keep going down.
can't post the image of the battery chart. Gonna make it more difficult to solve.
Just wondering where to look and if this is something that can be solved or is possibly a phone problem/defect. As I mentioned, mine works nice and I have it setup as close to my phone as possible to get results that can be compared.
first of all im no expert, but i think it could go either way. before assuming its hardware it wouldnt hurt to back everything up, try a factory reset and a wipe mk2 odin flash. then seeing if the issue persists. just throwing my thoughts out there. hope it gets resolved regardless. :good:

Have you tried Better Battery Stats + a Wakelock Detector? Between those two it should be really easy to see if this is a software problem or perhaps a bad battery.
I'll link you to the wakelock detector I use. In my opinion it's the easiest to use.
Here
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector
You can see wakelocks in BBS as well.... But I just like the options this one gives
Sent from my SCH-I545 using Tapatalk
I haven't tried BBS+, but Wakelock Detector has been running since the problem was detected. That is how I found the 1013 and Audio2_Out running. At the beginning it seemed to correlate with the problem but as time moved on it seemed less and less the culprit.
I haven't really found anything using wakelock detector. I could give you some stats off of it tonight when I have access to my wife's phone again.
Any stats that you'd like me to post I can do that. Eventually I'll be able to post that Battery Monitor Widget graph so you can see what is happening.
Pretty sure we can rule out a bad battery. About 99.9% sure.
First things first I would swap batteries between the two phones. Lets rule out a faulty battery first, because trying to figure out battery drain with a faulty battery can be maddening!

About a week and a half ago, my battery went from draining ten percent in a typical day (hour to an hour and a balf of constant use, browsing Facebook, web, email - if I really went ham I might go down in the 80s) to easily closing in on the 50s if not more.
I've tried several factory resets, gotten the lollipop upgrade that just hit, removed apps, upgraded apps - nothing. I'm on stock and haven't had this phone more than a month. Android System is typically the worst offender for battery usage according to the settings monitor.
Please help. I was so impressed and now I'm at a loss.
If you've done factory resets, then I would say, factory reset again and stay on stock apps. Don't install anything else. Monitor what happens with your battery life. My guess is, if you have installed other apps since doing the factory reset, it's an app that is misbehaving, even though you see android system being the main culprit. More than likely, it could be an app that isn't releasing resources correctly or hasn't been updated to run correctly with LP. That usually points to a sign of improper programming, or they haven't update their app yet to perform correctly under LP.
If things are running fine on stock, start adding your apps back one by one. Install one app, leave it for a few days and see what happens. if battery life stays the same, then move onto the next app. Hopefully, you'll find the app that's giving you issues.
If even with just stock apps you are having the issue, then it might be a hardware issue, possibly even battery. But, if it's been working fine before the LP update, I highly doubt that. My best guess is it's a misbehaving app.
I'm still having problems with nothing else but stock apps, unfortunately. The problem started shortly before the update - does that support that it's more hardware or more software related? The phone is still fairly new and though I know that doesn't rule out a bad battery, still kinda hoping I don't have to deal with Verizon and getting a replacement.
Talked to Verizon, they said "we checked, battery's fine." So... guess its not the battery? They said it "could take a month to normalize after the update."
I would buy a replacement battery and install it, see if that helps. They are cheap and it's good to have one anyway. The Ankers come in a 2-pack with a nice universal wall charger.
Verizon is not even bothering to check really, are they ? Did they even loan you a replacement to prove to you it's not a bad battery ? Doubt it. Do it yourself.
It really sounds like you are having excessive battery drain due to a wakelock problem like with Google's update service. Check around here for threads about how to diagnose and mitigate that.

I didn't expect Verizon to help, but they definitely impressed with just how little they offered. I'm spending today with Wi-Fi and 4G off, unless browsing, for which I turn the latter on. In my half hour lunch I've noticed much, much better battery usage. Thoughts?
Edit: change of location seems to drain it quicker (school vs McDonalds parking lot - former worse than the latter). Signal was three bars in each, though.
I've looked a bit ino wakelocks but will read up on it more tonight. Problem I've found is how many detectors require root access, and I'm not real interested in rooting.
I just got my G3 last night and rooted it and did a few things to minimize battery drain and today, after almost 12 hours of light to moderate use my battery is still sitting at 81%.
Pretty sure there's a memory leak on stock vs985 lollipop... Or at least from what I had read and experienced
