iOS 15 will become officially available to download sometime in the fall of 2021, with a specific date yet to be determined.

The public beta for iOS 15 became available to the public on June 30, 2021. We don't recommend using the public beta on a device you depend on day-to-day.

Which iPhones Can Get iOS 15?

If your iPhone is compatible with iOS 14, then you'll be able to get iOS 15 as well. This includes the iPhone 6S Plus and every iPhone model released after that (up to the iPhone 12, 12 Pro, and 12 Pro Max).

There are several ways to fix an iPhone that won't update, such as restarting the iPhone, pausing and restarting the update, double-checking your Apple ID, checking your storage, and making sure iPhone restrictions are off.
