Android OS using too much battery
- Thread starter alm0614
- Start date
If you charge it to 100% and take it off charger. Android OS will intentionally burn you down to ~90%..just to prolong the lifespann of the battery. read Your battery gauge is lying to you (and it's not such a bad thing) - xda-developers Its a lovely read 
Try charging it to 80% (where the battery is the happiest) and see if you still get a high drop because of the android OS

Heard something about some kernel issues..there probably are some issues that case the battery to drain..which is kind of expected since its a total revamp of the old android, Google is more than likely already on the problem in anycase ^^
In any case, taking short readings that include 100->80% is never reliable with li-on batteries. Just putting it out there

sounds about the same. Android OS is definitely doing something to keep the CPU awake much longer than it should. If you click on the Android OS process, mine says it kept the phone awake for 1hr 19m and 10s and used 22m of CPU time. Thats just outrageous that it is keeping the phone on for 25% of the time (phone has only been off charger 5 hours)

No no no! This is entirely not true. Android OS DOES NOT burn it down. It just doesn't allow the charger to charge all the way to 100%. What this means is if you don't have a 1% battery mod then you will think that the first 10% goes by REALLY quickly. Android OS does not, can not, will not, ever, burn your battery down.
This is a known bug that Google is trying to fix and nothing more. Please ignore the above. While the article is great it does not mean that at all.
^ This. Some phones have a buggy kernel that's keeping Android OS awake for hours on end. These phones have abnormally high OS usage. It's the reason some phones last 6 hours while others last 20-24hrs. Mine is one of the buggy ones. Yesterday my battery lasted 12hrs with a charge halfway through the day. Android OS was kept awake for 8hrs of that time. Definitely not normal. Hopefully we'll get a fix soon cause this really blows!
You're partially correct. You're correct with the fact that it doesnt use up unnecessary power and that it cuts it off before it reaches 100%.
BUT in the battery section in the OS it show a total percentage for whatever application that used up the power (hens always equals 100%)
Meaning: the phone reads the gauge at 100% and when it has dropped to ~97% the 3% has to have gone somewhere. This translates to whatever services has been used during that time (from the charger getting unplugged to the updating of the gauge) And so during that time it goes into the android os more than likely. I dont know if this goes automaticly into the android os or if it just gets split up on whatever processes that have been used during that timespan.

My Android OS is so thoughtful of my battery's health, it burns it down to shut down after only moderate use after 6 hours.
