iOS 9, the operating system software for iPad, iPhone and iPod touch, was unveiled during WWDC 2015 in June 2015 and finally became available to all on 16 September 2015. Then iOS 10 was unveiled a year later, at WWDC 2016. You've probably got three questions: can I update my iPhone or iPad to the latest version of iOS, should I update my iPhone or iPad to a new version of iOS and (if the answer to the first two is yes) how can I make the upgrade.
We'll address these questions in that order in our complete guide to iOS upgrades. We've also got details on how to install iOS 9's subsequent updates including iOS 9.3.4, how to install the beta version of iOS 10, and whether you should let Apple update your iPhone for you overnight.

The section below refers to iOS 9.1, where there was a bug in updating your device overnight. From our experience this is no longer the case with the newer revision, iOS 9.3.

With iOS 10 Beta 8, Apple is trying to encourage more users to install the incremental updates that provide fixes and small improvements by offering the chance to install them for you overnight when you are sleeping. If you're prompted to update your iPhone while you're using it, Apple now lets you choose 'Later,' which will then specify a time period during which it will update automatically for you if you've got your iPhone plugged in to a power source, which most people do overnight anyway.
When Apple prompted Macworld's own Ashleigh Allsopp to update to iOS 10 Beta 8 and offered me that 'Later' option, she decided to make the most of the convenient new feature. She expected to wake up in the morning as usual to an updated iPhone. And indeed she did, but she woke up more than an hour after her alarm was scheduled to go off. The update had worked brilliantly, but her alarm had been deactivated, causing her to be very late for work.
She's not the only one. Users have taken to social media and forums to express their annoyance with the issue, which we consider to be a bug, and many have been late for important meetings and school.
Therefore, we'd only recommend choosing the later option if you don't have to wake up at a particular time in the morning, or if you can set another alarm on a different
