Today Apple have released iOS 10.2.1 to the public after several weeks of testing. iOS 10.2.1 is a free over-the-air update available to all iOS 10 users. It can also be downloaded and installed on iOS devices using iTunes on a Mac or PC. The update on the iPhone 6 is 73MB and should take about 15 mins, the update does seem to hang but it will complete.
There are little to no visual improvements with this latest update, which would lead us to believe that this smaller update is geared towards bug fixes and performance improvements. Some 6s users have been experiencing issues with battery performance, possibly related to bugs.
