I'm about to smash this iPhone, after I updated to 9.3.4 the battery dies completely after 20 minutes of being charged overnight. Only thing I can think that went wrong... I used BatteryDoctor while the phone was inside a mophie, after that, the battery hasn't been the same. 1- battery drops from 100% to 80% within 5 minutes on instragram. 2- Phone dies at 60% battery life Anyone else having this issue?
