I have the same issue with Official Lineage 18.1... blank installation, still something drains my battery... (see here). Any ideas?I have been running the official flox ROM for a few weeks now and updating weekly. Using this ROM has been remarkably smooth considering the age of the device. I encountered no issues during installation and I had previously repartitioned to run unofficial ROMs. I used both Lineage recovery and ROM this time. Just a couple of observations I wanted to mention.
First off, the weekly update downloads but fails to install using Lineage recovery. I just sideloaded as a workaround. Secondly, and more strangely, I get significant battery drain of 2-3% per hour with the screen off. Same result for all releases. The only way I can mitigate this is through using an app like Naptime to force the OS to doze. When that is active, the screen off drain reduces to 0.7% per hour. has anyone else experienced this behaviour and if so are they aware of any solutions? Thanks.
