4.3 Charging control behavior (bug?) S9+ (star2lte)

Hi there(:

my device (4.3-20230731-star2lte) has a strange behavior when using “Automatic schedule” or “Custom schedule”. It charges to 80% stops, but immediately continues at 79%.

I do not know if that is healthy for the battery but it surely is annoying because the phone indicates it every time that it is charging again (sound, vibration, animation).

You can turn off the charging sound and vibration but not the visual effects as far as I know.

Maybe this is related to the lag of battery idle mode (maybe unsupported by some devices).

Thank you for looking into it (:
