I have accubattery. The app does not explain, it just state so. Wanted to know the technical explanation cause I heard it often.
been following the 20-75% rule for past 1.5 years
too bad there isn't any app or software-based solution to cutoff charging at set % ... other than external mechanical/digital timer to power socket
Accubattery can set the batt % you want to stop, but will not cut off. instead, it rings to prompt user to switch off the charger.
does it has the depth to protect the camera bump?
