All this week, some iPhone users have woken up to a nasty surprise: being incredibly late to work because their alarm got shut off. This iPhone bug happened to those who decided to use Apple’s ability to update to iOS 9.1 while they slept.
Overnight updates are a relatively new feature that has only been available since iOS 9.0. It seems so convenient. You make sure your iPhone is connected to its charger, click a button, go to sleep, and wake up with the new version of iOS installed.
If you haven’t updated to iOS 9.1 yet, it’s probably a good idea to do it while you’re awake.
We have reached out to Apple for comment.
