Boinc reads battery un correct when battery charger was plugged and battery percentage was 100% it suspended the projects and I was seeing messages the boinc will resume compute when battery reaches 90% current 100% what i should do to solve this problem
Thank you for your help

This is a known bug and the developers are aware of it. Appears to be affecting mostly devices using Android OS versions 10 and up.
Message boards : Android : Annoying bug
And here's the link to the work in progress> Known bug, see #5305 for progress on its development.

Basically it's an Android "battery / power saver" interference problem.

Currently the only know workaround right now is to adjust the device battery/ power saver settings and to exclude BOINC from these options as noted in above links.

The problem was solved completely when I uninstalled the original app that downloaded from boinc official website and reinstall the same version's app from f-droid website and I unchecked the battery optimize automatically and set it to manually
,, try that solve it worked for me perfectly
Thank you
