A few days ago, we warned you about how software updates can be the real culprit behind your gadget's diminished battery performance.
Although updates are supposed to bring new features, bug fixes, and security patches to your phone or tablet, there will always be unforeseen glitches along the way that may slip through the beta testing process. We even advised that you can usually postpone major software updates until all the bugs are worked out.
Although incremental, one such update that is reportedly causing battery issues is Apple's iOS 10.1.1 for iPhones and iPads.
According to a growing number of iPhone owners at Apple's official support forum, their phones are prematurely shutting down when their battery levels hit around the 30 percent mark.
Although this may point to hardware issues similar to the defective iPhone 6s batteries that Apple offered to replace, iPhone owners are also reporting that the affected 10.1.1 gadgets jump from a fully depleted battery to 30 percent in a matter of seconds after being plugged in.
A number of people also claim that their battery woes started manifesting after updating to 10.1.
These multiple reports and symptoms suggest that the degraded battery performance is due to the bugs in the 10.1 and 10.1.1 software updates rather than any hardware issues.
Apple actually released two different versions of iOS 10.1.1. The first version dropped on October 31 and it included, among other things, security patches and bug fixes for Health data. A second version was released on November 9 and this was only available for those who haven't updated yet. There is no information on why this second minor update was required.
As of this report, a few posts in Apple's support forum state that Apple is already aware of the issue and is now working on solutions to fix it.
It is not known how widespread this issue is but we have seen iPhones with iOS 10.1.1 that are not affected by this battery issue.
But for now, if you haven't updated to 10.1. or 10.1.1 yet, to avoid any potential battery level bugs similar to those reported by multiple users, it is best to postpone it until Apple releases an official fix.
