As soon as iOS 11 was released, many iPhone / iPad users performed OS updates and they were released one month earlierAndroid 8.0 OreoIt has been reported that the number of users has been overtaken as soon as possible. On the other hand, as there are so many users, the problem is also immediately banged out.

It is a mobile news siteWanderaThe survey of battery average wear rate over the past three days for 50,000 terminals showed that iOS 10 (green sign) had 240 minutes (4 hours) from full charge as opposed to, I found that iOS 11 (light blue sign) was 96 minutes (1 hour 36 minutes).


In the vicinity of Wandera, it was only 2.98% of Apple's terminals upgraded to iOS 11, so it is questionable whether the data size is sufficient, but actually I felt a problem with the battery The number of people are never small and reddit has too many people to complain about the battery of iOS 11, so "There is no such thing as a perfect state right after any app is released" I want somebody to write that they do not write the same thing.

One solution to the battery problem is to downgrade the OS, but due to the security problem of the old version OS, Wandera switches from iOS 11 to iOS 10.3.3 to extend the battery duration I am opposed to downgrading.
