FP4: Reaching charging control limit triggers a fast charge/non-charge loop

  • /e/ version: 2.5-t-20241108446629-official-FP4
  • Device model(s): FP4
  • Developer mode enabled: yes
  • Device rooted: no
  • Trackers blocker enabled: ?

Summary

Using charging control with a percentage limit will trigger charging/non-charging loop when reaching limit.

The problem

Steps to reproduce

  1. Go to Settings -> Battery -> Charging control
  2. Enable charging control and set limit to 80%
  3. Charge the phone and wait for it to charge up to 80%

What is the current behavior?

Phone will show non-charging/charging notification in a loop indefinitely until disconnected from a charger. It will also show charging/non-charging battery icon in status bar. I suspect the actual battery charging is also restarting and stopping in a loop.

What is the expected correct behavior?

Phone stops charging the battery for good and keeps level of battery charge while using it.

Please see the video with stressed lightning bolt battery icon in top right screen corner. Sorry for bad quality. stressed_lightning_bolt_battery_icon

This issue is not happening for FP3 so it seems to be FP4 specific.
