it says these packages are included in android system: Settings storage, input devices, theme chooser, key chain, settings, android system, google backup transfer
I don't see any of them that are rogue, and I didn't change any settings lately....

I think its built to start up automatically during certain actions such as wifi being turned on. You should be able to disable it in settings > apps. If you're rooted, you uninstall it.

I'm rooted but I don't want to completely uninstall it. For now I have disabled location services, so I will see how well that works.

Get titanium Backup and freeze it. When you need it just defrost it

Battery issues with 4.2.1?

Hello-
Ever since I updated to 4.2 and especially 4.2.1, battery life has not been the same. Today I went from 100% last night to 73% in 22 hours just in standby. I didn't change any settings that I can remember. Can anyone please help with this?
Thanks,
wws12

I had the same battery issues on 4.2 in standby...even with wifi disabled. I ended up flashing back to 4.1.2 and battery is back to normal. To me 4.1.2 is more stable and much smoother. Hopefully Google will fix these issues in the next update.

I noticed that a large portion of the battery is being used by something called "Media server" Any idea what that is or how to turn it off?

I'm also noticing the same sleep mode battery drain on 4.2.1,around 1% per hour..
I need to root my tablet to downgrade?

Use media scanner root from the play site and disable the media scanner. Then this battery drain should reduce.

Yes. Root access is a must.

I think in my case most of the battery issues was from the device being new and the software stats still needed more time to be accurate, that has happened to me on my Sony tablet also..
Now I can see some real stats as I use better battery stats app for keeping track of the battery.
I use my tablet as a use when needed device because it's not my notifications device that is always connected, for that I use my smartphone. That said I turn on airplane mode when I'm not using it and sync when needed as well.
Só when my Nexus 7 is in sleep mode it has very few apps and services running other than the system ones.
So the stats I came up with are:
1% in sleep mode with airplane mode on and Google Now and Location History turned on..
And..
0.3% in sleep mode with airplane mode and Google Now plus Location History off..
So for me no Google Now as I don't need that much.. It lasts 3x more in standby without it... And the truth is, in my country Google now for me isn't that useful as it is although I'm sure someday will be..

It's strange...with stock 4.2.1 no root I haven't any battery drain... 0.7% /hour with wifi on and sync enabled...In the battery stats, even if in a hour i turn on the display on a minute, the display takes at least 40% of battery...

Is there a way to disable Carrier IQ? It's annihilating my idle battery.

I keep my GPS off to help my battery life, but every once in a while the GPS turns itself on randomly and tries to get a lock. It's an issue because while I'm inside it really struggles to get a lock and eats battery like a mofo. I got to work with 97% battery and an hour and a half later I now have 85%.
What can I do to stop this from happening short of waiting for cyanogenmod?

Install System Tuner, free from market (lots of annoying ads, no big deal).
Click the red System Android, click Android System, Details, then uncheck all 7 CarrierIQ related processes.
Worked OK for me and no FC issues with calls or anything.

System_server

After upgrading to 4.4.2, I noticed a massive battery drain, and then noticed that in BBS system_server is taking quite a lot, any ideas what it is and how to stop it?

Change settings in some apps how frequent they should update. For example, update every 6 hours and change settings in Location to device only that might help. On my phone, I had a battery drain to zero just overnight. I disabled Google+ because I do not use it and in Google Play Services turn location off. I also wiped cache and dalvik cache in recovery and the battery drain stops.

I already switched off location, and disabled most unused apps, yet the drain is still here. Anybody else experiencing this issue?

Wrong screen.
To check what is draining your system, select in first tab: Partial Wakelocks.

What I meant is not an off screen battery drain, rather it is an onscreen battery drain that is far more quicker than 4.3, with my phone under normal usage having a maximum of like 1.5 hours of on screen time even though idle drain is low.

And I am telling you that this doesn't prove anything.
At same screen, I have much more use for system server in comparison to you, but in real life there is no problem.
So, don't worry about this.

Per process wake and cpu usage

Hi,
I'm trying to understand why phone is out if deep sleep so much.
When looking in most apps of battery/wake/cpu usage, i see that android system and android os are responsible to most of the usage. The problem is that all history accumulating apps do not breakdown the processes under "androud os" and "android system" .
I am looking for an app like that if anyone knows.
Thanks.

Hi bud!
Android System Tuner Free suggests it's LGE Gravity Sensor, so I am charging my phone to 100, Disabling "Knock-on" and see how it goes Stay tuned.
Thanks!

So far I am at 94%. 34 minutes of screen on time.
Android system usage still 19%
Android OS down to 10%
I seriously need help, seems like "Knock on" isn't the main culprit.
I hoped it's not that, as i really like it.

Me neither, though it's hard to tell right now with only 6-7% drained.
The phone is "harder" to use with knock-on disabled. I'll keep you tuned
If all you see in your app is android os and android system, then it does not drill down in them to show which of the processes/modules is consuming.
That's what I'm looking for.

Try both Android System Tuner Free and GSam Battery monitor.
Gsam is no good as it does not breakdown to apps in android system/os, but android tuner is great.
I see that most of my drain is from screen and after that it is lge_gravity_sensor and dhd_dpc which is wifi related.

Try disabling Google now. Also disable the Google location settings and I bet your battery life will double.
Never used google now.
Will try to disable location services.
Thanks : )
