Many Apple users have been reporting this annoying battery bug, but there was seemingly no fix for it – and Apple refused to acknowledge it was an issue. Apple says in a statement first reported by TechCrunch that it fixed the bug in the most recent version of iOS 10.2.1., which was released on January 23. With iOS 10.2.1, Apple made improvements to reduce occurrences of unexpected shutdowns that a small number of users were experiencing with their iPhone.
