Like any software release, the January 28 iOS 6.1 firmware update did fix some known bugs, but also has introduced a new set of issues. Specifically, the update is said to contain a bug that affects your iPhone’s battery life and 3G performance.
The battery inefficiencies could be related to an Exchange bug, clever people at AOL have learnt). Quick searches on the Apple Support Communities forum for iOS 6.1 battery and iOS 6.1 3G clearly prove these issues are more widespread than originally thought. While some people are seeing their iPhone 5 battery life dropping after updating to iOS 6.1, others are bitching about overheating issues.
To make matters worse, Vodafone advised its UK customers against upgrading to iOS 6.1 until Apple fixes 3G hiccups, which include the occasional difficulty in connecting to the network to make or receive calls or texts or connecting to the mobile Internet.
