How to fix iOS bug causing iPhone battery to drain rapidly

Several users have reported facing major battery issue with their iPhone devices after upgrading to iOS 10.1.1. Apple Support Forums were flooded with complaints of rapid battery-drain experienced by iPhone users after they upgraded their iOS. Some users reported as much as 60% battery drain occurring in idle mode or even when the device is turned off.

Apart from this, some users have reported on support forums that devices have shut down abruptly even though a good 30% battery charge remained. This issue has turned into a big controversy since while no official response has yet come from Apple regarding the battery issue.  All iPhone handsets ranging from iPhone 5 through iPhone 7 series are said to be facing the battery drain problems.


The Apple Support Forum page has numerous complaints with regard to the battery drain occurrence. One of the users writes: "Hello. Updated my iPhone 5 to iOS10.1 and have been having battery problems. It jumps from 30% charge to 1% in a few seconds then shuts down. Now here is the stranger part. As soon as it reboots after connecting to a charger it show 30% charge. When I unplug it right away it still shows 30% and runs like nothing happened for a good few hours. So it goes from zero charge to 30% in the time it takes to reboot? Strange. Shutting the phone down at night with a good 80% charge, it won't reboot in the morning due to no battery charge. I plug it in and its back to 30% in a few seconds."

Another user, adelphos195, writes: "I have had the battery replaced, well actually given a new 6s in replacement of my rapidly discharge one. I now can get over a days use from the new phone and it works as per normal. So definitely a HW issue of the phone. The phone or battery must be replaced. I also have an iPhone 5 which has a non Apple battery installed and it did not show any issue of discharging abnormally throughout iOS 10.1 through to 10.1.1."

Apple is yet to come out with a fix for the issue but in the meantime, some experts have come out with a solution to the batter drain issue. They have suggested disabling Raise to Wake feature which has helped them increase battery life on their iPhone 6s and iPhone 7. Some others have installed beta builds of the next iOS 10 update with hopes of temporarily resolving this issue.
