Have noticed that android OS seems to be using loads of my battery, even more than the screen this morning which is a bit odd I think. Why is this? Have only had about 25 min screen on this morning so far.

Is your sync on? If yes, then that's what is causing the high drain of Android OS. I personally just choose which Google Services are allowed to sync to minimize the drain of syncing of the Android OS.

Yes sync is on but only gmail, contacts, chrome and calendar. And gmail is the only thing that's synced in last 4 hours... Surely that can't be responsible?? Gnow is off too.

It's very likely caused by some app applying wake lock. I had a music player which was monitoring accelerometer for shake to change song feature. Then Android system started to drain a lot of battery. Battery life returned to normal after disabling that feature.
OK then. So is there a way I can see what process or app is causing that wake lock then, so I can disable it??

I had a similar problem with gmail a few days ago. I tried to send some pictures via gmail, but the content was to big to be sent. There wasn't a warning about this as it is in the web version. I deleted the drafts from the gmail app, while they tried to be sent. After this I left the phone on the desk and after a hour I noticed the bttery was about 20% down. So I force stoped gmail and cleared all data, after a restart all was on the right way.
I had some problems with the calender sync too, since I didn't use it I disabled the calender sync and so far no problems.
Don't worry about Android OS

Prior to 4.0, there were no wake locks computed for Android OS. It is now just the dumping ground for all of the time the device was awake that wasn't otherwise blamed on someone. So it is (total awake time) - (total app/system wake lock time) - (total screen on time).

If you are actually noticing tremendous battery drain and not just concerned with the high overall % of Android OS (which is NOT a problem) then get an app like Better Battery Stats and begin watching it.
Android OS = Apps running constantly in the background
When your phone is in deep sleep it shouldn't be draining any power, but it won't go to sleep if there's a app running even when the phone is not in use. If you're using the Facebook app, then that could be the main culprit for your battery power loss.

Hey guys wondering if its just me...
My battery is only lasting about 5 hours. And when I check the usage it turns out the calendar has used 62 % of my battery.
Does anyone know why this might be? I have a logcat which shows it tries to connect and fails but I don't know what the logcat means.
Any help?

Calendar ? Thats strange . The only thing that drains these beasts is the 4.3" display.

You could try disabling automatic syncing?
actually the only thing draining these things is the 3g. switch it back to gsm only mode and you will get nearly double the usage out of the battery.
pity we cant use the 2g toggle yet that is only available with the cyoagen mode

We can
Cyanogen for the DHD is now in beta.
I had this problem a couple of days ago. Noticed that battery was draining much quicker than normal, checked battery status, and calendar had used over 50% of the battery and had over 4 hours of CPU time when normally it is only a few seconds. Rebooted the phone and it went away. No idea what caused it though.
My 3g is no problem. I guess cus I get very good 3g and hardly drops it doesn't drain my phone searching for 3g signals. It's the display on mine even tho I adjusted the brightness

I recommend installing Juice Defender. Cuts off data connections when phone is asleep, then opens for a moment every 15 mins to sync. Saves me TONS of battery.
I had exaclty same problem. All you need to do to fix this is clear data and cache for calendar, calendar storage and calendar widget.
Since I did that (4 days ago) my calendar app works great
Just cleared my calendar cache and stuff, having the same problem as you can see:

Though it does not always happen with my DHD, I have seen similiar results to the screenshot posted by muppet0000.
My calendar is constantly draining 20% of the battery. I really dont think this should be the case. No more suggestions though I'm afraid.
I have the same, but my battery life is good

Interestingly, it uses 20% of the battery if I ever use the calendar.
i seem to have found a solution. i have taken off the facebook sync to calender. this seems to have stopped the problem. my calender is again 1% of my battery consumption.

I think mine's related to Facebook syncing contacts.
It seems to start syncing them, but just keeps going...
I've just cleared data on both Facebook apps. We'll see if it helps.
Hello, mine does the same, I am using SeePU and CPU is 100% usage from time to time for about 1-2 hours (I check it once in a while). Installed SystemPanel to check the process activity and it's com.htc.bgp which is using about 50% of the battery (16h25m of CPU usage).
When going to the Settings-->About phone-->Battery-->Battery Use, for a flash of a second the process com.htc.bgp appears on top, but then changes to "Calendar" and uses 40-50% of the battery.
I use as calendars the exchange e-mail and facebook (used only for birthday reminder sync). The problem appears also when I remove the exchange server so it seems this is caused by Facebook. Unfortunately, I can't find a solution for removing only the calendar (I can live without birthdays...) but still I need the contacts synced....
Any solution found so far?
Regards
Just few quick tips that will help you get amazing results:
1. get the app called Autostarts from the market
2. in the app kill after reboot google maps, talk and social hub(you can find it on scond line in the application from the possible options.
3. Get Titanium
freeze wifi sharing manager and wifi manager.
You are done
Enjoy!
Have you tried dl'ing anything from the market after doing this? Because in the help section it says you might not be able to dl anything from it if you disable Google Talk.
Why not just log out from Google Talk instead?

I just realized that I've madeb a mistake:

I think the point is to have it done automatically every time.
Exactly! You can stop them manually but they will reappear again. With the program mentioned above you can do it for good - google maps, google voice will not longer drain the battery without need. Tiatanium will take care for wifi sharing manager and wifi manager - yet another big, big battery drainer that won't affect the phone in any way
Thanks for the tip. I got the program autostarts but I am not able to manually disable google map and voice. I just see several lines of google services framework. Is this it?

Time to do some testing. I already had autostarts on another recommendation, but was lost on what to do with it.
I have found that using a very (very) minimal homescreen on a black background, using a dark profile for all apps that have the option, and turning wifi off when not needed, I can get at least 2 and a half days out of one charge with light use.
Going to see if this impacts my numbers any. Thanks!

The trick of my recommendation is that the phone is folling in deep sleep when not in use and by that way you can almost double the battery life, of course if not in constant use. To be sure that you are doing alright go get frkm tne market Battery monitor widget, install the widget and if you are running at about 50mA in sleep mode you are just fine.

Can you explain why rooting eliminates the need for the functions "sync" provides?
Do a factory reset. Syncing has nothing to do with this issue. I sync three emails, facebook and twitter. I am easily getting 15-20 hours with over 2 hours of screen-on time.

If there was a way to sync Google contacts only when a contact has been added on the device or from the web, I'd turn off autosync. The random syncs seem to be my problem, but I'd be up the creek without them.
Don't think sync is the culprit - I have had android phones for quite some time now and they all been sync'ing same amount of data - no such drain. This is something SGS3 specific. There's a lot of modules listed under Android System. One thing I suspect is that I switched network to EvDo/CDMA/Something/WCDMA, which might be not a particular good idea. Turned back to CDMA only, since LTE is not available here just yet (waiting for this damn Sunday!) and will see if that improves the stats.

I had GPS toggled on the past 2 days and got horrible battery life and high Android System use.
Toggled it off today and it has been much better.
The weather app likes to use it. And I also noticed it firing on randomly. Just turn it off. Maybe it's the GLONASS support, but it sucks down battery particularly well.
I wish Google would separate out Location permissions from GPS permissions. Then in CM9/10 we could just uncheck GPS permissions.
Some apps I like general location, but they have no business using GPS.
I have a Tmobile Note 3 and I am getting, in my opinion, horrible battery life, can anyone she'd some light on what's going on?/offer a fix? For the record this is rooted, however the problem was there since I got the phone

The latest firmware update has made battery life even worse.
Looks like a classic case of over-syncing...
Exhange services = Non-Gmail Sync. That won't cause a wakelock if it's set to manual.
Do you actually use Google Play Music? No? Disable it.
Do you have location services on?

If you're willing to sacrifice a bit of functionality for good old fashioned manual control, the best things to do are:
- Turn off all Sync options (so you have to manually retrieve email, update facebook and such)
- Turn off WiFi when you're not using it
- Turn off Mobile Data when you're not actively using it (when you turn off auto sync, leaving mobile data on is a bit pointless. ) This makes about 2 days of difference.
- Kill off as much bloatware as you can, the amount possible differs between root and non-root. (I'm not rooted.) Particularly the Google Play related and Samsung Hub apps tend to remain active even if you never use them. We never even had Google Play Music and Books here as they were US only, and yet the apps kept running anyway.
- Set the screen brightness as low as you find comfortable. I know the screen is gorgeous, but it's also one of the main drains
- Turn off GPS and all location settings (in both Settings and in Maps.)
- Disable all auto-update features in Google Play, Android itself and such
- Don't run too many widgets
- Black eats less battery than white in terms of screen drain (as black on AmoLED is a disabled led.) So a black background/wallpaper/theme on something will drain less than a White one. (Which makes all the white websites twice as irritating.)
If you get a decent battery life with all these settings, you can then decide one by one what is and isn't worth turning back on.
With 4.3, I believe Google services has started eating more battery. Have the same issue on note 2 4.3

Hi,
I have had my G2 for a few months now and have taken all the usual battery saving measures. On a normal work day, I can leave work with approx 60% battery left. No sync and no apps running in the background. I use task manager regularly and Clean Master to keep my battery lasting as long as possible. However, for no discernible reason, my battery has started running down at an alarming rate today. When i look at my running apps the list covers almost every app i have whereas normally it might have just a couple. I haven't downloaded any new apps or updated anyand my OS is up to date. Am i the only one experiencing this?
Thanks
Assuming you've already tried setting Location Mode to Battery Saving instead of High Accuracy, check to see what's consuming most of the battery (Settings--> Battery; tap on the battery icon).

If the problem is not to do with wakelocks, then it is probably due to a badly calibrated battery. Download two apps: advanced battery calibrator and batterycalibration. Follow the instructions of batterycalibration first. Then the next day, charge your phone to 100 percent, then follow the instructions on advanced battery calibrator.
That should fix the battery life.
However, if it is wakelocks, download wakelock detector from the play store and screenshot the cpu wakelocks page please. Then, post the results on here.
Hi, I have location turned off completely. Battery use says my screen display but that is set either to auto or 50% today, I normally have it on full and last the day easily. It's been great up until today, for some reason all the apps are running in the background within seconds of killing them all off.

Maybe some apps you started toda are draining lots of battery since there is always google/whatsapp or facebook and many other apps keeping synchronizing in the background. I dont know or you have facebook but i had that app and that drained alot of battery on my nexus 4.
Uninstall clean master and task manager, this apps draining a lot of energy. Make a hard reset after this.
