[Feature Request] (optionaly) disable background service on low battery / when energy saver kicks in

[ChristianTacke]

Is your feature request related to a problem? Please describe. I have enabled the "Run GNSS in background" option and sometimes forget to terminate the app (and the background measurements). This drains the battery somewhat and finally my battery is quite low.

Describe the solution you'd like When my battery reaches 30% (my setting), the device automatically enters energy saver mode. It would be great, if gpstest would disable/stop the background measurements at that time to save energy.

Describe alternatives you've considered

• Hmm. Trying to remember to disable it always if I don't need it any longer running in the background? I tried! I failed at times.
• I might take another look, why my OS (LineageOS) does not stop the app when energy saver starts. I probably put gpstest on the exception list. I should check…

Additional context Version: 3.10.2 OS: LineageOS 19.1
