My iPhone show a dash in front of maximum capacity why?
Phone: iphone 6s
Background: I always had problems with it(battery wise) and for sometime it could be only used while its charging but then if i were to disconnect it, it would die. So a couples a week ago i got it fixed and all of a sudden, it turns off and resets back to 1% and then goes to 16% then repeats (while charged) but now when i check the maximum capacity it says "----"
