If you just recently upgraded your iPhone to iOS 6.1 and noticed that the battery life seems to drain quickly or your device overheats then you are not alone. These issues which used to be reported only by a few users is soon swelling as more and more people are reporting in forums that they are suffering these issues after upgrading their operating system.
iOS 6.1 which was released last January 28 had several new features and included an expanded LTE support around the world. Interestingly enough the very first forum post on discussions.apple.com regarding this update comes from a person who reported great battery life on the iPhone 5. The people who replied to that post however had a different experience though as they said that their device was draining quickly.
Some of the replies were
“Sadly, I am seeing the exact opposite o_o. I hope this changes in a little while lol. My iPhone 5’s battery is going down pretty fast.”
“Now I am at 80% with 1 hour 34 minutes of usage. Seems nothing was done to improve battery. From my last reading 19% battery drain – for one hour of moderate usage – 4-5 web pages, and push notifications. That’s all.”
Various threads have already been started regarding this issue which now comprises several pages in the forum with lots of people complaining about the problem.
One possible cause of this is that Apple Mail and Microsoft Exchange seem to be going on a sync loop which causes the transaction logs to increase in the Exchange mailbox servers. This might also be the reason as to why only a particular group of people have this problem (those who use Exchange). Those who have not experienced this problem might not be using exchange at all.
One person reported that he performed a factory reset on his device which appears to have solved the problem.
Vodafone UK has already sent out a text blast to its subscribers using the iPhone 4S not to upgrade to iOS 6.1 due to problems with 3G performance. “If you’ve not already downloaded iOS 6.1 for your iPhone 4s, please hold off for the next version while Apple fixes 3G performance issues. Thanks”
The mobile carrier has also posted a notice in its support forums addressing the issue stating that “Some customers may occasionally experience difficulty in connecting to the network to make or receive calls or texts or to connect to the Internet. Apple is working on a solution to their software issue. These connection problems are intermittent.
While Apple’s investigations continue, we would recommend that anyone who has not yet installed iOS 6.1 on their iPhone 4s should delay doing so until Apple has confirmed that their problem has been fixed.”
We expect to hear an official statement about this concern from Apple soon
