battery life | battery drain of unknown origin
I will abandon this build for a while. I merely hope this post helps our community in some form of analysis.
The reason is, I am experiencing inexplicable battery drain with the latest two nightly releases. At first I thought it was the regular Gapps related bug, common workaounds also seemd to fix it. But very poor battery life recurred 5 days later.
It is not related to wake-locks. The phone is 2% active. And barely runs longer than 36h even with "Battery saving" and "Airplane mode" combined. And even these modes don't have any effect anymore. Using the phone hardly shortens the total time until the next recharge. The same setup ran 4.5 days previously with the same usage.
I did everything from clearing caches, resetting apps and the data, data-saving, limiting permissions for sensors, using Greenify, ditching instant messengers, push-notifications. All to no avail.
I'm guessing cpu government issues.
It is the first time I have problems with custom builds. It was a clean install, via TWRP 3.0.2. Later I added SuperSu; I doubt "addonsu" hosted on Lineageos.com would have made the difference.
Best of luck to everyone else. And thanks again to the devs and members for the great ROMs!
