First time repairing best approaches for iPhone 13
Wanting to change my iPhone 13 battery, I got a replacement non-oem battery done by a shop about year and half ago, the new battery just sucks capacity is down to 81% according to the phone and it feels like it has swollen a bit (back panel has got a very faint rise where the edge of the battery is). I‘m planning on changing it to an oem battery and want to DIY it but I’ve got no sense of how likely it is I’ll break it. Have built PCs before but never opened a phone before
