Yesterday the notfifier informed my that there was a new release for my phone. I updated my phone to “fp2-sibon-18.04.1” via the regular updater. The update was successfull but after approximately 4h I heard a ping which told be that I had only 18% battery left. When I started the update it was at 96%.
This morning it was at 100% when I left the house. After 2,5h and Surfing web pages for approximately 30 minutes it was down to 56%.
I didn’t install any new apps (But a few were updated the same day) but i feel the update did no good. The phone also is more than hand warm at the back side (upper area). I rebooted twice but there is no change.
if you take your battery out, plug in your phone so that it vibrates a few times, unplug it again, re-assemble the phone and charge it, the battery recognition by android is reset and (for me) it worked totally fine again. This is also a workaround for the general Android WiFi-drainage bug.
After I wrote the first entry to this forum and my battery was down at 57% after three hours without having performed any activities, I also checked the battery guide and waited until the battery was down to 1% and shutdown of my phone (It was around 2PM). At home I charged the phone again and wanted to check the battery consumption with the BetterBatteryStats App.
After I booted my phone again and hit the play store icon I wondered why the shop didn’t come up. And then I maybe became aware of what obviously happened: The Google Apps were gone! The OS update 18.04.1 rendered all google apps useless. They didn’t start anymore (Tried with maps and play store.
So I rebooted back to recovery and installed the OpenGapps pico ZIP file again for Android 6.
TO make it short: Everything is fine again. I guess that without google apps or services the OS was lacking a required service and either kept searching for it or connecting to it which caused the phone to become hot and the battery to loose capacity rapidly. I left home with 99% this morning and now it’s still at 59%. Its bad as well (I didn’t use it much: One 2 mins call and 20 minutes surfing the web) but I think its normal for the FP2.
