IOS 10
Some iOS 10.1.1 users reported that their devices were prone to unexpectedly shutting down at or around 30% battery charge (with one user describing the battery percentage as dropping unexpectedly from 30% to 1% before doing so, but still registering as 30% when plugging it in to charge it). Apple began the process of diagnosing this bug in iOS 10.2, and stated following the release of iOS 10.2.1 that it had reduced the occurrence of these shutdowns by "more than 80%" on iPhone 6S models and "over 70%" on iPhone 6 models. It also became possible to reboot the device after an unexpected shutdown without plugging it into power.
