warezhafid14 · Jun 28, 2014

Hey guys!

i have a battery drainage on my i8190.

Like if i leave my phone charged 100% and go to sleep i find it off in the morning.

i even tried greenify.

any suggestions?

kernel?

Thanks guys.

You don't add anything for anyone to help with. Post a screenshot of your battery stats maybe, or even install betterbatterystats, wakelock detector or something to see what's causing the drain.

So, this tells me that your phone has been awake about 23 mins while your screen was off. To know why you have to look at kernel wakelocks, and then take it further depending on what that will show.

There we find that PowerManagerService.Wakelocks is at top, and this is usually a sum of all partial wakelocks.
Then we have to look at partial wakelocks to see why.

Do you have location reporting turned off? You can check it in Settings - Location - Google Location Reporting.

So turn it off. "scanning always available" option (in wifi settings) drains a lot.

Hi mauam !

Yes but I do not think that would be the solution, because even with stock rom open wifi, the battery lasts long.
Any other ideas?
thank you
