No matter how awesome the operating system is, bugs are inevitable. Recently, some users complained on Apple's official forum that after upgrading to iOS 6.1, the battery life of their mobile phones has been greatly reduced, and their mobile phones are very hot. One user said that after upgrading his iPhone 5 to iOS 6.1, their mobile phones will lose 35% of their power in a night in standby mode.
Although this bug has a great impact on user experience, we believe Apple will fix this problem soon.
