Android system eating battery!

Hey guys, i got my Samsung S3 yesterday after having my S2x for 8 months. Really happy with the phone except for the battery life. My phone dropped 15% in 1 hour with screen on for 15 minute in Wi-Fi. This is the screen shot of my battery...

its syncing all your google stuff dude. aka contacts apps and any settings you have set to auto backup.

I'll try turning off sync for the day, see if that helps
Thanks for the reply!

Syncs a major killer, first think I turn off. If you root, theirs no need for most of the stuff it does

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.

Because you can use titanium back up for everything, I still use Google sync tho, the first days is the ones the takes the biggest hits after that I think is fine unless you keep updating contact and what not

I've got the same problem. I may try a factory reset as fillyo suggested.

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.

having the same problem in my Verizon s3

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.

[Q] Galaxy S4 standby doesnt work

So i've had the S4 since it got released and i like it,
but for some reason the standby doesnt work at all.. i have it set to turn off the screen after 30 secs of idle and it does not work.
anyone else having this issue?

mine works fine. see what apps have been installed. maybe some app requires not to go in standby and prevents the screen to go off

Have similar problem - screen do not off completely. Does not mateer what time I chose, does not matter if smart stay is on or off. I do not have it's icon visible in the status bar whet it is off. Anyway screen is always on. Any help?

Same problem here. The phone just dims its screen but it never shuts it off.
This is quite annoying when the phone lights up to show the low batt warning and just drains all its remaining energy. Perfect.

Try disabling all smart stay options (smart pause could still be on).

Seems that I found the reason. But still do not have permanent solution. After restart screen went off without problem. After running some application it became constantly on again. When I closed some applications (long press home button and swipe open applications) screen also turned off normally. So probably some application makes such a problem. Have to check which one.

Why my Services of google make the baterry bad ?

Try to disable all sync and disable location services. See if the battery improves and then activate sync one by one to see the culprit.

But I don't turn any sync or location on ?
any idea ?

Check in Google maps, turn off location history and location reporting. Turn off network location in location settings of it is on. If that doesn't help disable Google now. I had this exact issue and that fixed it.

It's common if you have WiFi and network location checked in your location settings. This forces the phone to randomly use these services, even if you turned them off.

Turn them all off. Reboot the phone and see how it looks in a few hours. It won't show instantly, takes time.
Go into Google Play services and clear data and reboot.

I do see high Android OS keep awake but it does not seems to affect the battery life much. When it is in standby for hours, the battery level hardly moves.

Battery does barely move during standby.

LOL I like the way you ask after you have done it.
Anyway, to answer your question, it is a feature used by some mobile service providers which in effect allows for a more efficient data service by not having to wake the device up to transfer packets of data. The converse is true if your provider doesn't support it. If your provider supports it, you want to leave it switched on. If your provider doesn't support it, turn it off.
My provider doesn't support it, so I turn mine off. You will have to Google to find out for sure if yours does. Don't rely on the gimps who work in shops/manage help desk calls to know. They most often don't and then just make their answer up.
Google is the best place to check.

I enable FD for the 3 network (UK) as it supports it, no battery issues

Google location keeps my device awake.

Hey guys, im using DBT latest official rom but it also happened on APC rom as well.
Sometimes when i unplug my phone from the charger in the morning, nlpwakelockCollector will keep the device awake until i shutdown location services and restart them. Anyone else encountered this issue ?

Most likely you have the location set to high accuracy,
change it's settings to "battery saver" which does not
use GPS to gain that high of an accuracy.
No need to shut down location services.
Good luck,
Have a great day!

Im having this issue too! Hope someone has other solution than turning off gps

Thats not a solution thats a bypass. Many devices have gps set to high. But location doesn't keep their device awake 100% of time.

I have high accuracy and don´t have this issue.
Maybe a clean cache works...

I already installed rom from scratch. It doesn't solve the issue.

Something tells me you have a rogue app that is asking for location via Google Play Services. The fact a location bug is following you around via different firmware tells me something you have installed yourself is the cause.

Couldn´t be google now? The Google App is always looking for position. ( and you can disable that permission).

Google now is off on my device. But when you think about it. This m8gjt be cause of Waze application. Ill try to disable it for few days and see.
