I’m having a lot of problems with my charging. Sometimes I connect the charging cable, the “charging” light turns on, but the device doesn’t charge (or charges extremely slowly, such as 1-2% overnight). Just disconnecting the cable and reconnecting fixes the issue. I think the charge socket is getting loose.

Are there apps where I can monitor the battery current? This would allow me to see when I have issues (also to do quality check on the various cables I have). Something onn F-Droid would be preferred.
