swollen battery for the second time, how come?
hi, about 3 months ago i've had an iphone 4 with swollen battery. i've replaced the battery and back cover.
today the customer is back again with the same problem. not as swollen as last time but still enough to crack the back cover...
(the phone is death if you put in the swollen battery)
what could be the reason for this? no signs of fall or water damage...
replacing the battery works but will this happen again?
Cette question est-elle utile ?
