Apple releases iOS 13 today, with hundreds of millions of iPhone users looking forward to getting their devices up to speed with the latest features, including the long-awaited dark mode. As opposed to last year, when iOS 12 was supported by all devices that also ran iOS 11, some users will be disappointed this time round.

Contrary to earlier rumors, iOS 13 will still be supported by the iPhone SE, but anyone still using an iPhone 5s, 6 or 6 Plus will be left behind. Considering that the iPhone 5s was released in 2013, users can't really complain about a lack of support though. Falling behind the curve after six years is something that many Android users can only dream of.

The following chart shows how long Apple has historically supported different iPhone models with the latest versions of its mobile operating system. iOS 13 will be supported by all iPhones from the 2015 iPhone 6s and 6s Plus onwards.
