My phone began to randomly switch off & wouldn't power on at all unless it was plugged in, & after 1 or 2 days it lost power completely. Did my research & all signs pointed to a faulty battery.
Pulled up ifixit's trusty repair guide on replacing the battery & in a matter of a couple minutes I was back in the game. The instructions are excellently detailed & made the process super simple.
Follow ifixit's guides & you are guaranteed to be in safe hands.
