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.
You’d probably want something closer to a USB C power meter. A killawatt would measure the overhead from the charger brick rectifying AC to DC. If you happen to have a killawatt on hand it would work fine most likely.
