Why Does My Iphone Keep Dying At 100. A pop-up will appear from the bottom of your phone screen. Your iPhones software is in charge of monitoring the amount of battery life remaining on your iPhone.

IPhone 6 died at 100 while charging and wont turn back on. My iPhone 6 died while it was getting charged by my Imac. And yes I tried DFUrecovery mode.
To stop this from happening the first thing you should do is to keep all of your apps updated.
Eg a month before my phone would die at around 40-50 now it dies at 90-100 This happened a while ago with the same phone and some how my phone fixed itself I dont know how it happened and it went back to normal dying at 0. If your watch isnt lasting all the way through the day its likely that you are using the watchs battery a lot more aggressively. Why your Apple Watch battery dies so fast and how to fix it. Fix an iPhone 6S or 6S Plus battery indicator that wont update.
