Heavy battery drain when not on flight mode

- Device model: FP3
- When it started to occur: unclear
- Reproducible with the last /e/ version: yes
- Reproducible with LineageOS: don't know

When the phone is not in flight mode, a battery drain of 3...4%/hour can be observed. This is mostly independend of using an app or not. In flight mode the battery drain is acceptably low.
- The device is unusable
- The bug is the source of a data loss or a big waste of time
- The bug concerns a third-party application
- The bug concerns security

The problem
Steps to reproduce
- disable flight mode
What is the current behavior?
Battery drain increases to 3...4% per hour, even when phone is not in use (e.g. during the night resting on a table)
What is the expected correct behavior?
Battery drain should be much lower, at least when the phone is not in use (it is acknowledged that there will be higher battery drain with data/connection on than without, of course).
Technical informations
Relevant logs (adb logcat)
I took several files (dump, logcat, dmesg) with BetterBatteryStats (latest XDA-version). Unfortunately, I have often been hit by the problem described in this issue (#1250), so I can't show the difference so easily in one log. (The phone crashes after disabling flight mode). So I'll try to deliver some screenshots and logs which I took during different use states: flight mode, wifi/mobile data on.
Relevant screenshots
In this screenshot you can clearly see the difference.
