Hello, I have a new P9 which loses 20-35% battery overnight. Is there any chance this is a Graphene issue?
AccuBattery and Gsam reports that Deep Sleep only occurs about 1 to 4 hours so that's 4-7 hours of the CPU being wakelocked during 8 hours idle.
Battery stats in Settings - all apps seem within normal limits, but System consumes high amounts overnight.
adb dumpsys batterystats logs tell me that GNSS and GPS are the battery drains and 'system' is the only user. No apps stand out.
I did a factory reset, installed barebones apps, and installed Google Play, and avoided GPS-using apps -but System is still consuming high battery.
Not sure where to go from here.
Can I disable Graphene's unique location handling?
Should I enable location services for Play Store? Maybe the Play Store is repeatedly requesting location and getting denied?
I also considered:
- It's just a bum battery and needs warranty replacement
Thanks!
