[Q] what is the Android OS?

I have both android system and Android OS listed in my battery use screen the android system uses 1% of my battery while the Android OS is using 58% of the battery and I have have no idea how to stop it or what is it...
I assume you are running Gingerbread 2.3.3. It's a bug . To stop it, reboot your device.

That's strange... the bug is caused because some apps which use the 3D module are not optimized to work with gingerbread and they keep running at background... but if you rebooted and it didn't stop, you should have installed an app which is draining your battery... try to remember which app did you installed before the drain appeared!
I know for those of us on the captivate with that issue it takes pulling the battery for a few minutes to get that issue to stop

Just curious, but do you have a reference/bug link for that one?
If you are on 2.3.3, that's probably the android OS battery drain bug.
http://forum.xda-developers.com/showthread.php?t=1039696&highlight=android+os+bug
If you install watchdog lite and allow it to monitor all system processes, you might see suspend taking up a lot of CPU. If you reboot, the battery stats may not have been cleared, but the bug may be temporarily gone for a while.
Easiest fix seems to be to flash 2.3.4. I have not had it since
Its probably the android operating system which is what your phone runs on.
It's probably pulse that is causing the battery drain I will check it out and report back

Android system hammering the battery

My missus' 4xhd is on 70% after 3.5 hours unplugged, she's looked at Facebook and on the wrb a little but nothing major. In the battery use menu it says android system 66%
Is this normal? Because my Xperia has been off charge longer and shows android system 6% massive difference there!!

I uninstalled all the games I had on my phone and battery afterwards was amazing. Not sure what games u had on ur phone but dead Trigger mass effect seemed like they used battery even if not played. Now star wars angry birds and contract Killer zombies 2 doesn't to use that much battery when not used. I think dead Trigger must be constantly be doing a task in the background. I got from 6 7 hours to 15 hours with 12% battery left. Not sure why some games in idle still or when not being played still eat the battery like crazy. So my tip is uninstall all games and see how it battery life is afterwards.

Facebook app is a battery eater, even when not in use. It's trying to sync contacts or others notifications constantly. Even when you disable those options.
Uninstall that app and use Facebook through a browser like Dolphin or so? That's what i do.
Also read the tips in this thread: http://forum.xda-developers.com/showthread.php?t=2013469
I'll post my final configuration in that thread soon. I have my phone at stand-by now for 6 hours and it's still at 100%.
I found the best way to save battery is to not use 'active/changing/moving" widgets, remove or freeze battery eating apps and underclock.

Before I didn't had any problems with Facebook (al sinc was OFF, notifications OFF, refreshing "1 hour", and no battery drain) but now,after todays update, everytime i turn it ON, the GPS starts to run. I disabled the "share location" option, everything but it still happening. The only way is to turn OFF the GPS...
Any ideas??? Cause I tried everything...

Wrong post.
Stock trega core concept is awesome but it depends on usage. As said in power Management demo, if screen is "on" and some background program is running all cores will be on, which consumed a lot of battery. And try charging your mobile only when charging falls to less than 5%
And remove it when it's fully charged. and I suggest you calibrating your battery really calibrating my battery worked a lot.
I have been vulgarly using my mobile a lot. i never faced any over consumption. Overall I am really happy with the results. of course I'm never disappointed by my battery till today. I love my 4X.

Good to note that you are happy with your battery. With 3G on, my battery does drain faster. Even overnight it goes down 7-8%. Could you explain how you calibrated your battery. I dont plan to root my phone.
Thx.

Without root you will not get good results.. Even if you calibrate your battery. In my opinion, the first step to get a better battery life is rooting your phone.
She doesn't have any games on her phone and yea Facebook runs but it does on mine and i don't have any issue with it. It never used to be that bad too. Just like this last week really

[Q] Android OS killing battery. Any solutions?

I don't know what's causing this. Anybody have the same situation as I have? Any ideas to remove Android OS battery drain? TIA
Remove Android OS from your system :thumbup::screwy::silly:
Seriously its core process of entire OS (operating system).
Without it your phone can't work

If your phone is rooted, download better battery stats from xda for free and find out what is draining your battery

Well, I got pissed and did a factory reset+flash new ROM and problem seemed to be solved. I'll get back if it's still present.

Every now and then i have the same problem, Android OS chewing my battery dry...it keeps my phone "Awake" all the time,like when i sleep for 8 hours it eats my battery over 30% ... but,after a restart or 2 or 3 restarts it gets back to its usual behavior,phone goes to sleep when i don't use it and i get easily 2 days of medium usage...
i still have stock ROM and dont know what keeps the Android OS working all the time in the background, but as i said it happens rarely,maybe 2-3 times a month,so probably its some sort of a glitch
P.S. @NoTricks , 2 months ago i installed Dropbox app and even i have had its settings not to upload anything automatically, the application was working all the time in the background killing my battery super fast...after i uninstalled it the phone went back to normal battery usage...just my personal experience with that app....

Yeah, Same Here, My battery drains faster when I install an app that always runs in background. I tweaked my S3 Mini's Minfree values and it helped a bit, but it reduced my phones powers in multitasking.

Why are Android OS and Android System draining my battery?

I've noticed this in the last couple of days that my battery is consumed very quickly by the Android OS and Android System processes. I cannot associate this battery drain to any new apps I might have installed.
Better battery stats has not helped much in identifying what the issue is and I regret paying for that app. This is very frustrating as my phone suddenly runs out of battery in about 10 hours instead of 14 to 15 hours.
If you suggest solutions, please don't suggest disabling or turning off any functionality. The point is to gain better battery, or to the level I used to have just a few days ago, without turning off things or installing other ROMs.
Maybe you're using to much data and gps. This android os draining are related to that. Use greenify and debloat some unused programs with tb.

Install an app like "wakelock detector". It will tell you what is waking your system.

Question How can I downgrade my phone from android 12 to android 11

I want to downgrade it because android 12 literally drain my battery.When i was on android 11 it stays for 2-3 days now only 1 please help
Did you do a factory reset?
If not, try that... best to do after a major firmware upgrade. That may solve the problem, however a lot of users are having Android 12 regrets.

Downgrading Moto devices is risky at best.

Sounds like a 3rd party app is causing it.
Find the root cause instead of messing with the firmware.
Take sd_shadow's advice...
Go to Settings > Battery > Battery usage.
There you will se what is Eating battery & choose Restricted.
On my phone the app for my smart watch eats 29% of battery... I restricted.
I suggest Don't restrict Android system & network, connection related app's.

Avoid using global power management as it will cause erratic behaviors and even increase battery usage long term.
Find and deal with problem app(s) directly. Try clearing it cache and data if needed.
In app settings try restricting its background internet and battery usage.
Toss it if not really needed...
Sometimes battery usage is misreported and a parent or dependency app may be the culprit.
Fun, no?
Play with it...
belkata_47​You are wright. It still devours the battery.
Second battery eater after my smart watch app is Android System. This i can NOT restrict.
blackhawk​I clean cache almost everyday with Motorola Help app.

You need to find what in Android Services is eating the battery. It may be a 3rd app that's conflicting or using an Android service.
A witch hunt...
@belkata_47​yours still eats battery?
Mine is settle. Now battery is fine. The app for smart watch is Force Stoped.
