I had an 4s that used to heat up, which caused the battery to drop from 100% to 20% within an hour. They have changed it for me.
But the same problem continues, it heats up and the battery drops, not that much as it used to, but it does twice or 3 times a day. I have been trying to solve it by deleting apps or pictures etc.
Is there any solution for this?
Thanks in advance!
