Apple has not announced an iOS 27.3 release date. Developers have had beta 1 since November 3, 2026, and the only dated commitment on Apple’s own pages is December, for Apple Intelligence in China.
For everyone else the real question is whether to install the beta now or wait. Any iPhone that runs iOS 27 can take the update, but the headline feature needs a newer phone, and that split decides who sees anything different on release day.
TL;DR: Apple has not set an iOS 27.3 release date. Beta 1 reached developers on November 3 and the public beta followed on November 5, and Apple’s only dated promise is December for Apple Intelligence in China. The update supports every iPhone that runs iOS 27, but the redesigned Health app needs an Apple Intelligence-enabled device.
What Apple has said about the iOS 27.3 release date
Apple’s pages give two timing signals, and neither is a date. Its newsroom post on the Health app says the redesign rolls out as a free software update later this year.
Apple’s China newsroom says Apple Intelligence reaches users there in December, when iOS 27.3 officially ships. That makes December the working window, though Apple has not said every feature lands everywhere on the same day.
Where the iOS 27.3 beta stands
Beta 1 reached registered developers on November 3, 2026, as build 24C5037i, according to Apple’s developer releases page. The same page lists matching 27.3 betas for iPadOS, macOS, tvOS, visionOS, watchOS and Xcode, and shows no second beta yet.
MacRumors reports that the public beta opened on November 5 with the same builds. You join through the free Apple Beta Software Program, then pick the public beta under Settings, General, Software Update, Beta Updates.
Back up first. Going back to iOS 27.2 means erasing the phone.
Which iPhones support iOS 27.3
Apple has not published a separate device list for iOS 27.3, so the iOS 27 list applies. Apple’s iOS page lists iPhone 11 and later, plus iPhone SE (2nd generation and later).
The catch is what you see after installing. An iPhone 11 owner can take 27.3 but will not get the Health redesign, because Apple says it needs an Apple Intelligence-enabled device, and Apple Intelligence runs on iPhone 15 Pro and later models.
| Item | What it needs |
|---|---|
| iOS 27.3 update | iPhone 11 and later, iPhone SE (2nd generation and later) |
| Redesigned Health app | Apple Intelligence-enabled iPhone or iPad |
| Health Age | Apple Watch |
| Apple Intelligence in China | iPhone 16 and later, iPhone Duo, iPhone 15 Pro, iPhone 15 Pro Max or iPhone Air |
What to expect in the update
The biggest confirmed change is the redesigned Health app, with Insights and Longevity tabs, Health Age, clinical lab results and camera based movement tests. Apple Intelligence for China ships in the same release, without Siri AI.
Testers have also found Safari vertical tabs in the beta, though how far they reach is unclear, and iPhone Duo Reachability is still beta only.
Apple’s developer release notes are short, and the largest item is a StoreKit change that lets customers buy multiple seats on a subscription, not something most iPhone owners will notice.
Who should install the beta and who should wait
If you want the Health redesign and own a supported iPhone, the public beta is the early route, and a spare phone is the safer place for it. Everyone else loses nothing by waiting for a December release, since the final build will carry the same features with fewer rough edges.
