After widespread reports of battery and connectivity issues coinciding with a software update, Apple iPhone 4S users have been advised to avoid upgrading their smartphone until the bug has been fixed. The latest version of iOS, iOS 6.1, was released last month, and has resulted in a flurry of complaints on internet forums.
Reports of such issues have been circulating for a few days, however Vodafone have now released an official warning to avoid downloading the software update, as have the network 3 in Austria.
The main issue appears to be significant drain on the battery life, as well as some overheating issues. Whilst some owners have reported their battery to be draining 33% more quickly, others have actually noticed a slight increase in performance. This disparity indicates that there may be some unexpected software conflict with one or more mobile Apps, that may contribute to this issue.
Other customers have experienced occasional difficulties with 3G network connectivity; having problems making or receiving calls and texts as well as internet connection issues. Others have noted specific issues with Exchange mail servers, some of which (but not all) have been solved by deleting and reinstalling their Exchange accounts.
Apple has informed Vodafone that they are working on a solution, and that such connection problems are ‘intermittent’. In the meantime, some users have found that restoring their handset with iTunes solves the problem. If you have not yet upgraded, it is advisable to delay this until Apple have confirmed that the problem is fixed.
