iOS 14.3 Reviews

If your iPhone is running on iOS 14.2.1 or iOS 14.2, you’ll see a pretty big download.

For most iOS 14.2.1/iOS 14.2 users, iOS 14.3 will fall somewhere around 700MB. The exact download size varies based on your iPhone model and the version of iOS it’s currently running.

If your iPhone is running on an older version of iOS, you’ll likely see an even bigger download because your upgrade includes the features and fixes from any iOS updates you skipped.

If your phone is running iOS 14.2.1 or iOS 14.2, the iOS 14.3 installation should take less than 15 minutes to complete. It took about eight minutes to install on an iPhone 12 Pro and about nine minutes to install on an iPhone X.
