Some iPhone 6S customers suffer a weird bug that switches off their phone at random.
The iPhone 6S is out since a week. There are about 13 million iPhone 6S units in use around the world. Some of these iPhones have though a bug that causes the device to switch off randomly.
Users on MacRumors pulled together a survey. From a sample of 200 iPhones, about 40% have encountered the switch off bug.
The bug has also been seen on older iPhones, but in much less numbers. There is no specific scenario when the bug hits. This means that iPhone 6S users might miss calls, because their phone has shut down in their pockets, without them knowing. The Apple Watch would show that the paired iPhone is off. Another reason to own an Apple Watch.
The affected iPhones need a forced restart to work again. This requires to hold the power and home button down for 10 seconds.
Apple has released the third beta of iOS 9.1 to developers earlier this week. It is though not known if the iOS 9.1 will fix this issue. iOS 9.1 is bringing the support for the iPad Pro coming in November.
It is possible that Apple will release an update to iOS 9 before November addressing issues like the random shut off issue.
