Apple iOS 10.1.1 update is already available to the Apple device users. However, though Apple has fixed the bugs pertaining to the serious problem with the inaccessibility of Apple Health date, two new problems were reported by the users.

According to Forbes, it has been reported that the iOS 10.1.1 update from Apple is already in the tech market for three weeks and the Apple device users are hitting the Support Communities forum with new complaints that Apple iPhone users are facing problems of 30 percent battery bugs.

iPhone users are literally angry over the behavior of their device where-in the battery goes down suddenly from 30 to 1 percent and turned off in a matter of seconds. This behavior from an iPhone has made the users quite surprised.  

The funny part is when the iPhone is connected to charger, after rebooting the battery percentage displayed is 30 percent, which is quite strange.

Forbes report shows the post from Mjolcresure, who explains the process:

"1 - 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.

2 - 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."

It is also reported that few iPhone users have witnessed the battery problems with iOS 10.1 and the newly update iOS 10.1.1 has not been provided with a fix by Apple. Apple might bring fix for the battery issue in the iOS 10.2 update which is expected to arrive in December.
