For the first few weeks I had my HD the battery life was brilliant. With minor use it'd have high levels like 95+% when I go to bed at night, but the last week or two something has begun really guzzling power from it and I can't figure out what.
I don't think I installed anything new, so I want to find out if there is a way I can easily identify where the power is getting drained so badly. For instance, some days now it is down to about 55% by the middle of the day without even making a call or using any data services etc. I have bluetooth & wifi switched off all the time too!
Is there an app that can identify battery drain in a similar sort of way to cpu/memory use? Or does it normally follow that something using more memory/cpu will be the cause?
Thanks guys!

Try the following task manager and click on CPU Usage at the top. This should help isolate what programs are active
Thanks very much for the reply.
I did look in a task manager I already had and I found that Phonex seemed to be varying but generally using up to 10% cpu just sitting in the background so I have uninstalled it (shame - it's nice).
I'll add in the task manager you've given me and check that, and see how it behaves now PhonEx is gone.....

Here's an update - I couldn't find anything else that was really using any cpu, and the main culprits using memory seem to be important stuff (I think - shell32.exe & device.exe & cprog.exe) so I doubt I can do anything about them.
Anyway, it wasn't bad last night after removing PhonEx but this morning it had used 10% battery in half an hour without even being used at all!!!
Rebooted and it's stayed on the same battery level now for over an hour but I don't trust it - it seems very erratic and I'm really not sure the best way to find the cause still.
I'd do a hard reset but it'll be a right PITA to get everything back on it again afterwards.

I would recommend reading this thread
A number of ideas have been given including using SQTools to identify what is using up the battery.
Good luck and keep me informed
Thanks for the reply again.
Are SKtools/SQtools two different things, or is that just a typo?
Have already got SKtools installed so I'll give it some scrutiny. It's obviously behaving at present though as it's an hour since my earlier post and still on the same battery % level.
Thanks for the link to the other thread anyway. I'll obviously be keeping a close eye on this so I'll advise any findings as they come up.
I've never known anything like it with this battery - no regular pattern sometimes brilliant sometimes awful. Very sensitive to chargers and type - one person reported here that if he charged through usb on computer his battery life went down really quickly afterwards. If he charged through mains battery life was much better. I also just found my charger on my motorbike has a small amount of rust/dirt in it and is causing the device to discharge.
I am not helping but just reaffirming your findings. I did find a programme called BattLog useful to see what programmes were causing high level battery usage. I don't have the link but you can find it here somewhere using search. Another tool for your collection.
Good luck!
Battlog eh? Thanks for the suggestion - will look it up
*edit* here it is - I'll try this tonight, if only as it's quicker than going through the SKtools menus to get to the power usage:
http://www.freewarepocketpc.net/ppc-download-battlog.html
I just began uninstalling stuff to see if it helps (seems to currently run around 106-111mah drain - no idea what might be considered 'normal' and have seen other posts questioning this but no real answers - yet).
Uninstalled Memmaid, and the wedge 18 tab action screen, and also Singh's 15 tab thingy. Have also turned off Handy Switcher as I had that running from startup. It's still drawing 106mah after all that!
One side effect though after removing those, was the weather applet appeared on S2U2 when I unlocked it - first time it's worked! It did disappear again though so there's still a problem with that too.
I've seen many posts where people blame software they have installed and the developer denies it is the software etc.... I think in the end it comes down to the device/battery or manila/TF3D. I may be wrong of course and will be interested to see how you go with it all.
I think it must be software since I have a lot on there and it was fine for the first few weeks I owned it and then suddenly began losing LOADS of power.
For some reason my data connection is not working now either! Might be time for a hard reset I guess.
If you are getting ~150mah consumption when the unit is in use, then with a standard 1350mah battery the lifetime should be 9 hours per charge.
If your battery dies in 1 day, then the unit is consuming the same amount of power almost all the time, even when it's locked or sleeping and this is not normal, unless you want it this way.
Some software, in particular lock managers and button managers are believed to be causing battery drain as they prevent the device from entering deeper sleep states where power can be conserved.
There's software floating on this forum that enables wi-fi and wave audio drivers to remain active in unattended mode (when your backlight is off) too, battery is drained a lot faster when any of these are installed.
Good points
I doubt there's any way of monitoring what power is being used in standby mode is there?
For instance, would an app be possible so that when sync'd and usb charging turned off the app on your desktop could run the same power monitoring process that you find in the likes of SKtools? That would answer a lot of questions I think!
PowerGuard
I used PowerGuard, when I was troubleshooting my battery problems ... and you can run the monitor and put it in standby mode, backlight off etc. I used to consume ~180maH when on, no calls no bluetooth and ~96mAh when backlight off/standby.
For me the culprits were S2U2 and Enable HSDPA in the phone settings. I cant get 3G cause im in the US, but it was alwys searching for a signal... after disabling those two.. im at 115mAH when on and 33mAh when standby and back to an ~18 hour battery life.
Oh dear, I just made a new thread with the same question really Silly me.
What version of S2U2 are you using? Did you upgrade that recently? I moved up to 1.5 and I think that might be the culprit, but I've uninstalled it and still having poor battery problems.
**EDIT** Okay, so I have Battlog installed, the drain sometimes shows as -330ma, but how do I see what is causing that drain?
My battery was lasting 2 days on the standard rom, using S2U2 and with HSDPA enabled.
I then upgraded to the Davideuck V-1 HP, and changed the radio from 1.09 to 1.12. Again I did have SU2U installed.
The battery then lasted about 6 hours, and the unit shut down before the ending of my day at work. I can only assume that the pda was consuming too much power even when switched off.
After two frustrating days, I gave up last night, and installed Davideuck V6 and changed the radio to 1.10, and now the pda battery is lasting for ages. It's only dropped from 100% to 99% after 5 hours.
OK, I know I should have changed things one step at a time, but I must assume that either the 1.12 radio or the V-1 rom is causing the problem.
I don't think S2U2 is the culprit here. But I do suspect that it might be the V-1 rom, as I believe that some folk have a similar problem with the new Dutty rom too. However, other users of the V-1 rom assure me that they don't have such a problem, so I'm confused!
Hmm, Dutty's 2.0 is using radio 1.09. Maybe I should try 1.10? Where can I get it from?

There should be for example "Active Application=ThumbcalStart" just above the temp/ma figures in the log file like in this screen shot post 17.
I am guessing 330ma does not sound too excessive for an open application as long as it is not running all the time.
So, idle it's at around 90-100. When I turned it off and S2U2 didn't start, it dropped down to 33 fairly steady. When I locked S2U2 and then turned it off, it stayed around 80, dropped to 50 for a little while and then came back up to 99...
I know this issue has been posted in forums for other devices, but I haven't seen anything about it for NC. I did try to search the NC forums but couldn't find anything that seemed to address this problem.
I am using MIUI 1.7.22. I have noticed significant battery drain due to Android OS (in battery stats), suspend (in the systempanel app), and event/o (also in systempanel). I have disabled auto-sync and any apps that appear to be likely culprits (those that might attempt to download data). This problem seems to appear with wifi on or off, and when on, I have tried both setting it to never turn off and to turn off when the screen is off. Initially I was experiencing battery drain due to cell standby, which I took care of by disabling the telephony provider, phone, and mms apks. I know many don't believe this has an effect, but I did it anyway. The cell standby drain is gone, but now I'm fighting the drain due to these other factors. Has anyone found a fix for this?
After scouting around for info, I have tried some suggestions seen elsewhere: rebooting and wiping dalvik cache. So far today I haven't had any Android OS, etc. issues. Standby life with screen off is as it should be (for now and hopefully forever)--very slow battery drain.
This is with wifi set to never shut off, which I prefer.
Suspend etc. came back last night although not as extreme as before. Hopefully some other folks will have things to add to this thread. I will continue posting progress info as I learn more about this.
From the code.google.com forums:
Confirm heavy battery drain with enabled Location & Security -> Use wireless networks / Use GPS satellites. I've disable both options and now my battery life is normal.
With enabled "Location & Security" options battery eaten by "Android OS" process (about 40-55%).
I will try this and report back.
Disabling WIFI and GPS in location/security had no effect. There appears to be a google process that prevents the system from sleeping.
I was still experiencing random battery drain due to Android OS, suspend, event/0 after switching to cm7. One suggestion I read was to disable calendar sync, as this appears to be a runaway process that attempts to connect to the server constantly without allowing the device to sleep. Doing this allowed me to get through the night with very little drain and the Android OS, etc. processes were finally behaving (within normal limits).
I'm not sure if anyone is reading this thread but I will continue to update until I figure out the solution, as I imagine this problem will become more noticeable to others who are equally frustrated with this issue.

Right now I'm using cm7 (2.3.5) but I was using MIUI before. Turning off calendar sync has worked well so far.
I had bad battery drain in the past and no deep sleep. but what worked for me was not to use any live wall paper. this fixed my deep sleep issues. for the battery drain, re-set your battery stats and re boot a couple of times for the stats to settle down. also check google map and latitude. in latitude just log out. un-checking sync in my yahoo email app also helped with my battery drain. my wifi is set at, off with screen. I went from 20 -30% drain in 7hrs to now 1-3% in 7hrs
I hope any of this info can help

Thank you, boxcar. I had tried all of those things (froze live wallpaper, reset battery stats, reboot, froze maps and latitude) but the only thing that worked for me was unchecking the box for calendar sync. Email sync and wifi appear to be non-issues--no difference between off or on. Evidently this google calendar sync bug is a known issue (that very few people seem to know about!). I hope google will fix this soon.
I also have same problem on my Galaxy S2. These two(events/0, suspend) drain many battery, 14% one night, without WIFI, GPS, Bluetooth.
I'll keep on tracing this issue, and share the result in this thread.

Turning off autosync seems to help the most (although setting WIFI to turn off when the screen turns off appears to help, as well). I tried using an autosync toggle but just turning it on at all seemed to result in a gradual creeping up of the Android OS, etc. problems. Manual sync of calendar and perhaps gmail and contacts seems to be the way to go. For some reason, exchange mail set to push results in no problems. The other trick I've found is to go to applications, then calendar and calendar storage, and force stop, delete cache, and THEN manual sync of calendar (reboot, recovery, wipe dalvik, fix permissions are good ideas, too). When I flash nightlies, I go through this process and the offending processes work as they should. If I don't, problems appear sooner or later.
I've had my nook on for 9 hours now, WIFI on (off with screen off) and 30 minutes of display on time. I've lost 9%, so I think I'm on the right track. This is how it should work, I.think. Of course, the results SHOULD be the same with autosync on, but manual sync for good battery life is an acceptable small tradeoff in my opinion.

Menu, settings, accounts and sync (I leave background data checked).
I found part of the root cause, maybe some old application - can work on new version, but drain many battery. Today I uninstalled the 'Android photo widget', then only 1% battery has been drained within 2 hours when standby. Not totally solved the issue, but seems OK.
I guess you can also try this, find another 'bad' application which drains your battery.
Well guys, I'm not sure if I'm the last Nook Color user to continue fighting with this super annoying headache (I know SGS2 users are, too), but I think I'm on to something. I thought calendar sync was the culprit (and perhaps it was), but the Android OS drain (featuring nemeses suspend and event/0) would not go away and the arrival of this problem continued to be (apparently) random. I had an idea that, if the calendar sync kept alternating between suspend and event/0, perhaps this was due to old events that caused the sync process to continue longer than it would normally. So, based on this idea and logic, I changed my exchange e-mail account settings to sync email from the last month rather than to sync all mail. Looking at my work e-mail history, I realized I had e-mails in various folders and sent mail from as far back as 2001! Although it's nice to be able to access all e-mail history, perhaps the polling services were constantly monitoring the activity of super old emails and folders, which caused the suspend and event/0 processes to flip out. I don't know if this is the way Android actually works but it seemed logical to me. Well, for the last 24 hours, I have intermittently checked my cpu activity through systempanel, and what do you know, when the device is not being used, suspend and event/0 work as they are supposed to and Android OS stays low in the battery % list. PLEASE let this be the fix! I know there are other factors that contribute to the acting out of these processes, but on a stripped down device with no autosync or widgets and no out of control services identified in systempanel or watchdog, there can't be many other explanations. I'm curious if others with this problem have similar settings on their email accounts. In all the forums on different sites (and I've read a ton of them), I've never seen anything like this mentioned.

Please vote there, and, may be, Google will fix it.
For those still following this thread, here's a tip. Use Gemini app manager (in the market). This has been one of the best tools I've found for managing wakelock issues and battery drain during standby. It allows you to identify apps that start up on their own (more than you think) and prevent them from starting randomly. In my experience this has been a huge cause of the standby drain problem showing up as Android OS, suspend, and event/0 in battery monitors. I'm currently sitting on 81% battery remaining with over 1 hour of screen time after 21 hours since my last charge. I know it's not a lot of usage but it's the standby time that's fantastic.

I've a Galaxy S2. Tried everything, except disable autosync. Was losing 30-40% battery at night. So far since turning off google sync I'm getting about <1% battery use an hour. Will see if it continues. Thanks.
Hello.
I've been searching various forums for a fortnight now to try and diagnose an SII issue I've been having and Google inevitably brings me here. Unfortunately, the numerous threads on battery drain don't match the problem I've had and the solutions haven't helped.
Around two weeks ago I noticed the battery life on my handset was really terrible, draining in hours. I had been using it quite a bit at the time so assumed this was the cause. However, lately it has been draining within around 6-10 hours even when idle, usually dying completely overnight despite a full charge just before then. I don't have a huge number of apps installed - maybe 20, fairly standard ones like Twitter, Facebook, Amazon, no games and no 'battery defender' style apps. It's not rooted (it's 4.0.3) and I can't root it for other reasons.
The battery drain was a nightmare, basically going from power point to power point just to keep it topped up enough to use and it was draining during idle time and deep sleep. I very rarely ever have 3G, GPS or Bluetooth switched on. Wireless is on most of the time and it generally does have a signal in the two places I spend most time (home and work). It also has a strong Vodafone signal since I'm living in a major city centre.
I tried a few things:
1. Uninstalled all but the most-used apps I had. No change.
2. Uninstalled everything it was possible to uninstall. No change.
3. Installed BetterBatteryStats and CPU Spy. BBS plus many hours of searching kernel/partial wakelocks and so on showed nothing that looked odd at all, certainly nothing taking up a lot of time or regularly stirring the phone. CPU Spy showed it did deep sleep when idle.
4. Factory reset. This included no app installations except BBS, disabling the likes of Social Hub, Gaming Hub and all other stock apps I could. No tethering or wifi sharing, no wifi, no 3G, no GPS, no Bluetooth, nothing running. It was basically a handset sitting there doing nothing. BBS showed nothing odd that I could see but the battery still drains in hours. No partial wakelocks and a tiny number of kernel wakelocks taking up next to no time and occurring a handful of times. No change.
5. I charged it before bed, took the battery out and left it until morning. In the morning it was down at 79%. This seemed weird so I bought a brand new genuine Samsung battery and gave that a try. No change in the 6-10 hour drain but taking the battery out overnight showed no drain now.
6. The weirdest of all. I charged it fully before bed, switched it off over night and it was drained completely by morning. That seems crazy to me. I can fully understand poor software or bugs draining a battery but not when a handset is switched off.
I am lucky enough to be able to get a new handset through work but this issue really annoys me. I took very good care of the phone, never installed anything crazy, didn't over charge it, the handset never got warm at any time, I'm careful with Wifi/GPS/Bluetooth/3G and location services, yet I ended up with an effectively useless "mobile" phone.
Is there anything that comes to mind that could have caused this? Point 5 above made me think it was simply a battery issue and maybe it partly was (with two batteries, how unlucky) but point 6 is just crazy. What could cause a handset to drain a battery under these circumstances?
Thanks for any advice!
Take the phone to Samsung Service Centre. No phone should drain that quick when un-rooted and a full wipe has been done
Sounds like tha battery is shot.

Um...widgets? Some widgets on stock Samsung ROMs kills your battery - I remember AP mobile news is a huge drainer. Try limiting the number of widgets you put on your homescreens maybe?
Hi...
Try:
01 - Full Wipe
02 - Install a clean ROM
03 - Disable Fast Dormancy ( *#9900*# )
04 - I use the GreenBatterySaver
After post your result !
I sugges too full reflash the stock rom and after count the batter time. If it does not help, it cold be HW error too - maybe it isn't.
Bear with me. If you are an expert on android maybe you can help me out here. First off, I have researched the crap out of this problem and still been unable to fix it, so YES, I did search before making this thread.
I am on a stock, rooted Verizon Galaxy S4. I have been watching my battery consumption carefully via the integrated battery settings menu, battery stats plus and wakelock detector apps. Mainly, there is a program or set of programs that typically is called "Google Services" that according to the integrated battery menu is consuming anywhere between 20-45% of my battery, sometimes more than the screen on time! My battery life is around 48hrs with 10hrs screen time but that is on the massive zerolemon 7500mah battery which I just bought, so I am not sure if that is above, below or just average (i.e. I have no real standard by which to judge).
Like I said I have read probably every thread about this problem with remedies such as; disable location, turn off google now, turn off google maps reporting, uninstall updates for google play/google play services/google framework settings, turn off google sync etc. I have tried them ALL, none seem to work. I have a feeling the issue is perhaps more in depth and above my head.
It gets more complicated. Although the stock android integrated battery menu reports it as using a massive amount of battery, the other two apps I mentioned above do not even report it, or at least not under a name that I regonize (perhaps that categorize it under a different process?). Under them screen time is by far the highest consumer.
So what to make of this? Is it a false report that the stock integrated android battery menu is reporting, and thus something to disregard? I doubt that because there are many other threads out there of people with the same problem and questions I have. But It's also not like my battery drains within hours. For instance, today I have been off the charge for 12.5hrs, with 3hrs and 40min of screen time and have 63% remaining on the 7500mah zerolemon extended battery.
If you can help, please do. If this is indeed a major drain I would really like to fix it.

Yes that seems to work, but it's not really a "fix" as now I cannot use the location feature of many of my apps. Basically traded one problem for another, albeit lesser one.
I'm still trying to figure it out as since last update (MEA firmware) , my phone is heating a lot.
I had this problem with data connection on, I had this problem in airplane mode, but not strangely with having connection to wifi.
I also observed that google services and android system is consuming most of the battery. earlier when I used to get 8-10% consumption in full use in an hour, now, 8-10 % is consumed within 30 mins.
No tweaks are working. Frozen a bunch of apps but the problem is still there.
Just now I've uninstalled fileexpert HD , as "greenify" told me that since last 20 minutes my phone is on, it has taken 250+ wake locks.
I'm charging my battery to full to check if that solves my problem.
will try to disable location services and report back on the results.
Bump
Have the exact same problem, before the latest firmware my phone had awesome battery life, and now the battery goes from 40% to zero in just a few hours without any app running when I'm sleeping... it's horrible. Same problem with my wife's S4 since the latest update... It absolutely sucks.
Hello everyone,
I come to you in the hope of finding a solution to my problem.
It's been a few months since I noticed that my battery did not hold the load, so I decided to replace it.
Unfortunately it was just slightly better.
So I installed the GSam Battery Monitor to see what was going on. I was able to notice that my CPU consumption reached peaks at 100% especially when I am connected to the Internet.
I have tried various solutions to fix this without success, so I decided to change version of LineageOS (I was on LineageOS 15).
So I went to LineageOS 16 with factory reset.
Unfortunately the problem is still present.
You will find attached screenshots of my problem.
It shows a use of my battery to 63% by applications, mostly by the system as we can see.
Between 6:45 and 8:45 I lost about 40% and I was "only" using Google news, Twitter (CPU peaks are linked to that drain I think).
Not to mention the fact that I lost about 10% between 00:30 and 06:30 without using it.
Thanks for your help
Just a quick update, i've noticed that the CPU goes back to 0% when on airplane mode, and go back to 100% once deactivated.
My signal is full on I'm not on data.
Is LineageOS16 incompatible with French network?
