Why does my iPhone randomly reboot?
I've recently replaced the screen on my iPhone 4s with success but to my dismay, my iPhone randomly restarts. During the tear down of the iPhone i accidentally ripped the ribbon to the battery connecter and the battery resulting in me having to buy another battery off of ebay. Now i don't know if this issue could be because of the aftermarket battery, or a malfunctioning in the logic board (i hope not!). The phone worked fine before i replaced the screen, and I have not had any other problems. The reason I think this issue might be the battery us because sometimes when the iPhone restarts it shows different battery percentages i.e 28% then after restart it could be 14%. The phone is also not water damaged. Any help would be much appreciated!
