Does anyone know how to fix my battery?
Every since the iOS 9 update, and the last two, my phone's battery has literally stopped working properly. My battery will go from 91% to 75% in 15 seconds. How do I know? I made a 15 second call to my mother and that happened. This has never happened before until this sorry update. I have turned off the background refresh, deleted apps, restarted my phone and yet, nothing has changed. I'm really disappointed in this update. I want my phone fixed because I am not paying for another iPhone. It was fine until this update. Need feedback ASAP. Thank you
