IOS 10.1.1 cries iPhone 6S/6/5S: battery is almost crippled

Apple hasn't come up with a perfect solution to the abnormal automatic shutdown of the iPhone 6S, and now there's trouble again.

Many Apple fans complained crazily on the Apple forum, upgrading to the iPhone of iOS 10.1.1, the battery life of the phone was so bad that, speechless, it automatically turned off when the battery reached a certain amount of remaining power.

The affected devices include older models such as the iPhone 6, the iPhone 5S and the iPhone 5, and some iPhone 6 users even complain that the phone automatically shuts down in just 20 minutes after upgrading iOS 10.1.1.

In addition, some users exaggerated that when they used iPhone to read a text message, the battery loss dropped from 100% to 43%, which was simply unbearable.
