If all else fails, you can always see the latest release of iOS listed on Apple's support website under 'Get the latest software updates from Apple.' Those listings show compatible devices, too. Apple traditionally supports older iPhones with iOS updates for about five years before moving on.Īnother reason that you might not see an update is that when Apple releases new versions of iOS, it rolls them out by region over the course of about a day, so if you're anticipating a download but it hasn't shown up yet, check again later in the day. The most common reason is that you have an older iPhone and the latest update isn't compatible with your device. If you know that there's a newer version of iOS available, but you aren't seeing it when you check for updates, there could be a few reasons why.

If there's no update available, you'll see the message 'Your iPhone software is up to date' in the 'Software' section of the page. Then, click 'Download' and follow the onscreen instructions. If you'd like to install it, perform a backup first. If there's an update available, you'll see it listed.
