Solution for Android OS being top battery user

[ido1985]

Hello everyone,

a while ago i posted here about android os using 30%+ of battery and being my top battery user. since it has jumped to 50%+.
yesterday i found this thread on xda:
[Q] msm_hsic_host wakelock - xda-developers
which discusses the problem. they don't find any definitive solution but i did follow some of the fixes they listed there, and since my android os has dropped to 10%, which is great.
they were:
- disabling everything in settings>wireless>cell broadcasts
- disabling exchange services
- disabling location services (in the 4 different places they are listed)

i don't know if all of them are actually needed for the improvement, but that's what i did. i actually had location services turned off for a while with no effect, so i think its probably the first two that made the difference.

i thought i'd share since it took me ages to find something that helped.

I also found out (a while ago on my Nexus S so it may not apply to Nexus 4) that if you uncheck the "backup my data" and "automatic restore" options when you first sign into your account on your phone (as in initial set up) then this also really helps keep android OS under control. I've done this on my new Nexus 4 as well just in case. The downsides of course are if you've already set up your phone you'd need to wipe it and start again and also your apps wont automatically sync back down so you'd have to manually get the apps you want (personally I never trusted that process to get ALL the apps I like, its always been hit and miss for me). If you have Root and can do a Titanium backup (or whatever backup you like) then this process isnt as annoying but I, especially on my Nexus S really recommended it. Hope that helps someone if they're having the Android OS battery drain issue along with your recommendations of course.

Somebody has got to be on top. The fact that it is the operating system may just mean that you aren't doing much with other apps or sub-systems.

update: it has improved my battery life dramatically.
before the changes i was getting about 14 hrs max with 2.5 hrs of screen time, which isnt bad.
right now im on running 13 hrs with 1hr of screen time and the battery is only at 61%.

You obviously dont use your phone much. 1hour of screen ON out of 13hrs the phone has been off the charger....thats why u are doing much better lol

maybe, but for the exact same usage i was getting 50% android os battery usage and half the battery time. its a proportional improvement. anyway, i shared what worked for me.

I'm on AOKP ROM i don't see the cell broadcast settings.

EDIT: is it safe to disable exchange services? i see it has something to do with email.

There is a small button on the right side of your phone, if you push and hold it for a while the battery will last a LONG time.

for cell broadcasts:
settings>under wireless & networks: more... > cell broadcasts > turn everything off

Maybe AOKP removed that setting

- disabling exchange services

When exchange services are enabling, my battery drains at an alarming rate. See this thread. http://forums.androidcentral.com/go...s-exchange-email-client-draining-battery.html

Anyone else track their battery drain back to exchange active sync?

I've tried w/ and w/o push. Push at varying intervals. Manual sync. No avail. When is enabled, it drains my battery.
