iOS 27 beta 5, released to developers on Monday, contains hidden code that references six unreleased iPhone models. The references appear in system files linked to armes battery drivers and Battery Intelligence features, including V62 – iPhone Air 2, V63 – iPhone 18 Pro, and V64 – iPhone 18 Pro Max.

This marks the first time the entire iPhone 18 lineup is mentioned in code found in an iOS 27 beta. The internal Apple identifiers match earlier leaks and have been cited by Bloomberg’s Mark Gurman, allowing analysts to match them to the expected iPhone models.

Apple has not publicly confirmed any upcoming iPhone 18 devices, but the models have been heavily rumored for months. The company plans a split‑launch strategy: the iPhone 18 Pro, 18 Pro Max, and foldable iPhone Ultra will debut in September, while the standard iPhone 18, 18e, and Air 2 will launch in spring 2027.

Related roundups include iOS 27, iPadOS 27, and iPhone 18 updates on MacRumors.
