I have a 3 1/2 year old 5S phone that is either having battery issues or battery management issues. How do I tell the difference?
I have a 3 1/2 year old 5S phone that is either having battery issues or battery management issues. How do I tell the difference? It jumps from 60% down to 10% in a heart beat and back up as much sometimes when plugged in for only 5 minutes.
