Apple rolled out iOS 18.3 this week, delivering several key new Apple Intelligence features to all compatible iPhones. Chief among them are new Visual Intelligence features, which use Apple’s AI to tell you about the world around you.
For example, if you have an iPhone 16, you can use its camera and Camera Control button to identify specific plants, animals, and insects. You can also use the same method for event flyers and posters, which will automatically add those events to your iPhone’s Calendar app.
(Note: only iPhone 16 models — not the iPhone 15 Pro/Max — support Visual Intelligence features, as the iPhone needs to have the new Camera Control button.)

A new default setting
But iOS 18.3 also changed an iPhone setting. In the past, iPhone 16 and iPhone 15 Pro/Max owners have had to manually turn on Apple Intelligence if they wanted to access those features. But with iOS 18.3, it turns Apple Intelligence on by default.
This means that if you have one of the newest iPhones (or last year’s Pros) and you download the latest software, 7GB of data — the amount needed to support all Apple Intelligence’s various features — will eat into your iPhone’s storage.
