Several unexpected shutdowns a day on the FP3 with /e/OS but not with FairphoneOS

• /e/ version: 0.14, maybe 0.15
• Device model(s): FP3

Summary

See more in the thread.

Two years with no problems on FairphoneOS.

The shutdown problem started to occur a few hours after the installation of /e/OS.

The problem

Steps to reproduce

What is the current behavior?

At home (so on Wi-Fi) it happens rarely, 1-2 times a day.

When this happens sometimes the phone is completely in standby mode (like during the night), sometimes it happens when I listen to music, sometimes it happens while I am simply actively using it (like writing a message).

While in the car it happens very often, even 3-4 times an hour, with or without Maps.

What is the expected correct behavior?
