I have my phone running 99.6% of the time in spare parts and it shows android system as the culprit holding a partial wakelock.
so my question is, how do i fix this? i've tried a factory reset three times, am updated to 1.21 ota and have slowly started to reintegrate apps but it always starts again and always after a different app.
i'm getting pretty frustrated anyone got any ideas?
UPDATE In my case it was network time abusing wireless location service that was causing the problem and hence the reason a factory reset didnt solve it, i switched off network time and voila!
just to clarify, no live wallpapers, and phone is in airplane mode to avoid any data usage drainig the battery.
i have got beautiful widgets homescreen small clock and pure cal widget installed at the moment but even when i uninstall them it doesnt fix it, also im running launcher pro 0.4.2 but also had the problem when i reverted to sense.
and i have read every other thread here about battery life that i could find but no-one seems to have this problemo
anyone with any advice on why my phone wont sleep?
A long shot, but go in to Mobile Settings and untick Enable always-on mobile data.

ok cool, giving that i try now but i had been leaving it in airplane mode to try and take the vagaries of data out of the equation.
this started about a week ago and i really noticed it when i was in a 6 hour long meeting and my battery basically draines 60% even though the phone was in airplane mode
ok tried that but with my phone just factory reset, airplane mode and no apps installed other than spare parts it's showing running 94.1 % of the time and all of it is android system.
that cant be right
i have restored data, maybe i shouldnt restore data either but that just seems plain crazy
Re: Android system - partial wake lock
What exact foreground and background processes/services do you have running when this is happening, any idea?
Apps like System Panel can show you them and some useful other details. That is certainly too high.

ok right now there is
com.android.syncml.service
sense
market
messages
people
rss reader
syncml provider
sys panel
touch input
updater
and then a load of inactive cached applications
do you see anything unusual there?
ok so i downloaded system app and killed all apps except excluded and sytem apps and my running usage has gone down, now thats no suprise in and of itself but now i need to see if it stays down.
i've just checked again and the percentage is still going down, so it's either an inactive app which i didnt list ( is that even possible if its inactive) or one of the items i listed above.
has anyone got any thoughts.
What do the logs say upon going to standby? (Use aLogcat to watch/save system log).
I had same problem I tried the turning off network always on to off, didn't change anything. the thing that worked for me was turning off my flickr account!? For some reason it kept my calendar awake so keeping system from sleeping, don't ask me why as I can't figure it out, though since doing this I'm now getting up to 2 days of average use from the battery. Also I've done the usual of reducing the different accounts sync timings etc.
Have you typed *#*#4636#*#* into the phone key pad to look at what is happening? This can give valuable info on what's draining the battery.

I have the same problem as OP since the latest update. The *#*#4636#*#* code is not helping in this case. The partial wake lock is displayed as Android System - which doesn't tell me anything.
I read something about the Calendar issues but I am unable to stop the calendar in running processes.
How did you solve your problem?

Ok i seem to have had some luck since last night though i'm not sure of the exact reason.
i did as th3 said and downloaded system monitor and then killed all background active and inactive tasks and that seems to have solved the problem. I have no idea why that would be the case though and i am watching it carefully to see if it stays fixed.
i dont have a flickr account setup

Djet, I installed alogcat and have found all references to wakelock, rather than post the entire log
D/PowerManagerService( 77): wakelock: PARTIAL_WAKE_LOCK 'NetworkLocation Check Location' activated (minState=0)
D/PowerManagerService( 77): wakelock: PARTIAL_WAKE_LOCK 'NetworkLocation Check Location' activated (minState=0)
D/PowerManagerService( 77): wakelock: PARTIAL_WAKE_LOCK 'keyguardWakeAndHandOff' activated (minState=0)
D/PowerManagerService( 77): wakelock: FULL_WAKE_LOCK 'keyguard'ACQUIRE_CAUSES_WAKEUP activated (minState=3)
there are also some entries in red like this one
E/vold ( 53): Unable to lookup media '/devices/platform/msm_sdcc.1/mmc_host/mmc0/mmc0:0001'
and a load of errors to do with global search etc but this is all pretty much gobbledegook to me, what am i looking for?
thanks
ok so based on that log i have switched of the use wireless networks to find my location (not gps i hardly ever use that anyway) and now the running % is dropping fast.
i will keep you posted as to whether it keeps coming down or not.
it is going to be an enormous bummer if i cant use wireless location, thats one of a smartphones greatest powers, why would this suddenly start happening now ( started about a week before the ota update) and continues even when i factory reset.

I suppose it's not the feature itself guilty but the applications using it. I had the same issue with battery running out because of Location service wake locks. It turned out one of the Locale app plugins was abusing this service. Having it uninstalled battery run became normal.

Yes i know what you mean, how did you go about diagnosing that? also i have done several factory resets and it still happens
Re: Android system - partial wake lock
There are a many app settings that drain battery and the stock setup is nothing I am fond of. Location/locale was one of them for me, calendar, network time and widget/app syncs being the others. A non-stock app causing such problems was NetCounter.
Calendar was fixed by killing it and restarting it. It's a known bug for many.
If many widgets are running sync very often, then you can imagine battery draining fast.

th3 you are legend, it was network time, i switched that off and all is now well in the world. cheers dude
Good find. I had the thing off anyway, but it is good to know.
I am having battery issues, almost to the point that I want to take this beautiful phone back. I have adjusted every setting I know to adjust, including the CDMA fix (was already on cdma). I am getting about 6 hours max out of my phone with light usage (maybe 20 mins worth of calls, 10-15 emails, 10-20 text, 15 mins. or so of internet/facebook usage). One thing I notice a lot throughout the day is that my 3g upload and download arrows seem as though they are lit up more times than not. I am wondering if there is some hidden fix that maybe I am missing that would help with this. I checked sprint.com's data usage tool and see that I have downloaded 1.2gigs of info in 3 days (seems excessively high to me). I also notice today that my phone was pretty warm to the touch for a few hours straight. Back to being cool now.
any help or ideas would be greatly appreciated.

Get a task killer, that is most likely caused by background application traffic.
You can also uninstall some apps that may "poll" the internet that you happen to not use.
Got Advanced Task Killer already set up to kill on screen close. Appears as though my damn calendar is literally sucking the life out of my battery and I have no idea how to turn it off. Went in to Applications and did a "touch to close" deal, but returns. This phone may be making a return back to sprint...nice toy, but actually need it to last more than a few hours at a time. Any way to delete calendar without rooting?

Do you also have a sync symbol always lit up? My EVO had some problems with syncing and wouldn't allow me to go into the Accounts and Sync settings. My fault - I had removed some .apks that it turns out I needed so my phone was constantly trying to poll it and giving me 100% Running time. Download Spare Parts and look at your battery history and see if you're getting Running to be high, or look at your Up Time versus Awake Time.
If they're high, go into Accounts and Sync in your settings and look at the options there. You may just need to turn off Auto-Sync to fix your battery issue so that it stops constantly polling your calendar.
Is there any way to stop this? Is there any way to find out what can be causing this? My battery life is pretty ****ty, and I only now found out that my phone should sleep at some point. It shouldn't stay awake for 40 hours.
I think I've fixed it. I installed AdvancedTaskKiller and set it to kill Calendar every time I shut off my screen. Calendar was my leading wakelock problem with 99%.
I also shut off the Calendar agenda widget and cut back on the auto-syncing. I'll keep adding these things back until I hit the problem again (If I ever do, with the Calendar on auto-kill)
Are you running the stock rom? There are a ton of battery tips, just use the search. However a lot of the roms have all the tips/settings built in by default to save you the trouble.
I am using Fresh 0.3 and I get over a 24 hours of battery with light-moderate usage.

My Calendar has been killing my battery recently too...I don't know what's going on. I'm running Fresh .2 (haven't gotten the chance to complete part 2 of root yet).
Hi,
posted this over at the Cyanogenmod forum already, but xda-audience is probably bigger making it more likely to find help ;-)

I am new to CM (came from Modaco ;-) and i would be extremly happy with CM 6.1 if i would not have one very stange issue:
My Phone suddenly stops sleeping exactly at midnight.
It all started when i found that it looses a huge amount of battery over night - it was one of the first days i used CM when i noticed this. As i am experienced with android i immediately checked my up/awake stats and found it was not sleeping properly. As the basic advice for this is always to find the "bad" app that is preventing sleep i treid something and finally thought the issue was gone. The phone was behaving properly the whole day.
Then i got the same issue the next night again !?
To finally sort this is ou, i installed juiceplotter and saw that ...
...the phone behaves fine until midnight - then it stops sleeping and drains huge amount of battery !!
When i start using the phone in the morning again - it seems to behave ok again (sometimes i rebooted - but i think just starting to use the screen again helps as well - not finally sure about this)
So the usual steps to check every single app via uninstalling (which i have all used with MCR-Rom without any problems) would take a while with my 70+ apps as i would always have to wait until midnight passes to see if i found the right one.
Any idea how to find the reason (app) that stops my phone from sleeping after midnight ? Mist be some app that also triggers something at midnight ?
Or any other idea what this could be ? (if not a 3´rd party app)
I checked logcat but could not find anything abvious.
Would really keep staying with CM and not nandroid back to MCR.
Thx
Marcus
It could be an app that is trying to sync at the start of the new day, thus starting exactly at midnight.
In the *#*#4636#*#* menu in battery history select the first drop down menu to "partial wake usage" and see if you can find which process is consuming the most resources in sleep mode.
It is likely that it's a third party app, but you can check that by booting in safe mode and leaving the phone over night to see if it happens again.
If as you say just by starting to use the phone the slowness disappers, it may be an app that is only working when the phone is idle (e.g. some maintenance app, antivirus, etc.).
Thx for the tips.
I checked most of them already ;-)
I found that "E-Mail" was 2nd in the "partial wake" list.
I configured an exchange-account there but set the sync interval to "never".
Nevertheless it is shown (only) with some 20 mins. (for ~6 hours standby) in the partial-wake-list - I found that suspicious.
After some googling today i found this:
http://code.google.com/p/android/issues/detail?id=9307
(this thread says that there is a bug (confirmed by google) that can prevent sleep with exchange-account set to sync never)
I tried to experiment today a little bit (also with setting the clock to 23:55 and wait a while for "midnight" to pass ;-) with different settings and found that "push"-setting shows better results (hard to tell with only ~30 mins. of stats each time). And now i tried with manual sync set to 1 hour (max) and see if that makes any difference.
I´ll dig a little deeper and post results.
In the meantime any tips or comments are warmly welcome. ;-)
Marcus
EDIT: If that "Exchange-bug" should be the reason - i just wonder why midnight seems to be a trigger - but who knows what went wrong deep in the code ;-)
confirmed:
It really WAS the Email-Client configured for Exchange.
No with setting it to "Push" everything is working fine .. when setting the sync to "never" Email start to keep wake-locks !
So everybody with a poor batt-performance should probably check this (if using Exchange) and use "push" until Google has fixed this bug (see above).

So, I've been having battery issues for awhile now, and they only got worse with the most recent Sprint update. I'm not a battery management rookie, and I've been consuming info on posts and threads for some time now trying to figure out the issue. Turning off options or syncs doesn't seem to do anything (and I've toggled almost everything off and on with no measurable effect to battery).
MediaServer was an issue for awhile, and I went through and located and pulled all 0kb media files and MediaServer has dropped back down to no longer being a major wakelock/battery issue.
I have no one app that seems to the issue when I check SETTINGS->Battery, or GSAM battery stats or WakeLock Detector. It's always just "Android System" and "Kernal". But I have noticed over the past several days that "VOICEMAIL" in consistently in the top THREE when it comes to WakeLock (see photo).
Problem is, I haven't received more than a handful of calls in the past several days (I mostly use texts to communicate. Just preference - don't judge), and none of them used voicemail. Why would voicemail be at the top of the wake list?
Any ideas on this one? I can't really uninstall voicemail (I tried to "disable" it in settings, but that's not really possible...understandably), plus I would like to keep it around. It's a bit of a necessity with phones.
I am running a Sprint GS3 on the newest update and unrooted (although I might root again if that would solve the problem). I am going to try and do a factory wipe today and start over again to see if that solves the issue (I've already wiped CACHE and that did very little). Maybe updating made something not work with each other.
I've been searching threads for a few days now, and I see nothing about voicemail and battery drain. Is it supposed to be that high on the list? Am I missing something else?
Thanks.
K--
EDIT - Oh, and the phone has been off the charger for only 2 hours and it has dropped 20% while NOT BEING USED at all...aside from sitting in my pocket. The apps that are opened are because for ten minutes I went through and wrote down what I needed to reinstall after the factory wipe. I had tapped some of the apps while moving screens around. It was at about 83% before I started that process. That can't be "normal" for battery.
