Apple has been promoting Apple Intelligence pretty heavily since the company announced the AI feature back in June, but it's honestly been pretty disappointing. However, with each point upgrade that Apple releases, it does improve, and the same can be said for iOS 18.3.
On Monday, Apple announced the release of iOS 18.3, which isn't a major update, but does bring a few upgrades to Visual Intelligence, changes to notification summaries and a new (old) feature to the Calculator app.
With Visual Intelligence, which is exclusive to the iPhone 16 models, you can now add an event to the Calendar app by scanning a poster or flyer with your camera. Visual Intelligence can now also identify plants and animals. As for notification summaries, they're now italicized, so that you clearly know it's a summary, and you can disable the AI feature on a per-app basis from your lock screen. It's also now permanently disabled for news apps.
As long as you own a compatible Apple Intelligence device, you can download iOS 18.3 today and get all the latest AI features. Here's everything you need to know.
Which iPhone models support Apple Intelligence?
Every iPhone model after the iPhone XS and iPhone 11 can run iOS 18, only some of the most recent models support Apple Intelligence. This is every iPhone that supports Apple Intelligence:
As mentioned above, only iPhone 16 users will get Visual Intelligence, the AI-powered visual search feature.
Apple Intelligence also works on iPad and Mac models with the M1 chip and later.
Only the iPhone 16 running iOS 18.3 has Visual Intelligence.
Now, do these six things before installing iOS 18.3
You don't necessarily need to do all of these things to download iOS 18.3 on your iPhone, but it will definitely make the download experience go so much easier:
- Backup your iPhone. You never know what can go wrong when updating, so it's good to have a backup. On your iPhone, go to Settings > [your name] > iCloud > iCloud Backup and tap on Back Up Now.
- Update to iOS 18.2. This will make the updating run smoother than going from iOS 18 to iOS 18.3.
- Charge your iPhone or connect it to power. You don't want your battery dying when you download a new software update, so make sure to keep it charged to at least over 20% or just plug it into power while you update.
- Connect your iPhone to a decent Wi-Fi network. You can download iOS 18.3 using mobile data, but it will be slow and could fail if your service is bad.
- Check to see if your iPhone has enough storage. Every iOS software update needs enough storage to successfully download and install. If you're running out of storage, go to Settings > General > iPhone Storage and delete large files and apps. You can also download iOS 18.3 using your computer, which doesn't require you to free up storage on your phone.
- If you haven't already, join the Apple Intelligence waitlist. Go to Settings > Apple Intelligence & Siri and tap Join the Apple Intelligence Waitlist. It should take a few hours for you to get approved. You also have to waitlist to use Genmoji and Image Playground.
To check out Apple's new AI, you must have an eligible device and run the current iOS 18.1, iPadOS 18.1 or MacOS 15.1. (On the iPhone side, that's basically the current iPhone 16 models plus last year's iPhone 15 Pro and Pro Max.) You'll also need to join the waitlist in the Settings app, but Apple Support says it usually only takes a few hours to gain access. Once approved, you'll receive a notification saying it's ready to activate on your device.
