Apple’s latest iOS update, 10.1.1 promises, among other things, “stability improvements and bug fixes.” But some believe it’s also carrying a new battery bug which either makes the battery to malfunction or drain fast.

According to a report by PCMag.com the update is unexpectedly draining iPhone batteries. There’s also an active discussion on Apple’s own support site where customers are reporting iPhone 6 and iPhone 5S devices unable to last a full day without charging. Others report iPhones dying with “30 to 50% charge left.”
The report comes just a week after Apple agreed to replace the batteries on a small number of iPhone 6s devices that were fast becoming faulty.
Some users who have opted into Apple’s open beta program report that version 10.1.1 (14B150) solves the problem while some also complained that it was not helpful.
The beta program is now offering version 10.2. Some in the forum have opted to roll back to a previous iOS version. One user on the Apple support forum reported that a rollback didn’t help, either. Said JimS-in-Seattle
According to him, “Don’t waste your time on rolling back to 10.1. I unfortunately confirmed faysal22’s comment that 10.1 does not work. My phone is lasting about 3 hours now. Instead of the battery shutting down at 70% it is now shutting down at 85%. I cannot tell you how many calls I have been bumped from. BTW, when it happens my phone is essentially dead for about 10 minutes before I can use it again.”
In addition to early shutdowns and rapid battery drain, others in a News forum reported that the Battery Consumption numbers given in Apple’s Battery Percentage Table seemed way off. “Varying apps are listed as huge battery sucks even when I don’t think they are (Calculator anybody?!?),” noted one frustrated user.
On the other hand, Apple has been known to release a buggy iOS update or two. Usually it recognizes the issue quickly and delivers a patch.
