Question: can ios 13 be on iphone 5?
Answer: iOS 13 compatibility: iOS 13 is compatible with a lot of iPhones – as long you have the iPhone 6S or iPhone SE or newer. Yes, that means both iPhone 5S and iPhone 6 don't make the list and are forever stuck with iOS 12.4. 1, but Apple didn't make any cuts for iOS 12, so it's just catching up in 2019. Fair.
