Wife dropped the phone at least 4 times resulting in the battery connector eventually severing from the battery itself.
Repair went smooth thanks to the install guide iFixit provides online. Just cumbersome because the screws are so small and I get afraid of losing them lol.
iFixit makes almost all possible repairs as painlessly as possible by providing as much detailed information as they can. For something simple like this, just look over their provided install pics a couple of times and take your time.
