The upcoming iOS 18 is expected to run on a broad range of iPhone models, including devices from the XR family onward and newer Apple smartphones. This assessment comes from Apple-focused reporting and corroborating sources cited by MacRumors, which suggests the update footprint will be similar to that of iOS 17. In practical terms, this means a lineup that includes the iPhone 15 series (15, 15 Plus, 15 Pro, 15 Pro Max), as well as the 14 family (14, 14 Plus, 14 Pro, 14 Pro Max), continuing through the 13 line (13, 13 mini, 13 Pro, 13 Pro Max) and the 12 and 11 generations, along with the iPhone XS, XS Max, XR, and the SE models from the 2nd generation onward.
For iPadOS 18, the strategy differs slightly. The update is expected to reach iPads powered by A10X Fusion processors and newer, which places a number of older tablets outside the supported range. First-generation 10.5-inch iPad Pro devices and second-generation 12.9-inch iPad Pro units released in 2017 are not anticipated to receive iPadOS 18. Similarly, iPad mini and iPad Air models released before 2019 are unlikely to gain access to the new system.
Apple is widely anticipated to unveil iOS 18 and iPadOS 18 at the annual WWDC developer conference, typically held in June. If the announcements align with tradition, the public launch window is likely to be in September, following the usual seasonal rollout pattern for Apple software.
Reports also hint at refinements that could arrive with iOS 18, including improved display capabilities and continued enhancements to graphics performance on ProMotion-enabled devices, along with broader Always-On Display features. These elements would fit within Apple’s ongoing emphasis on efficiency, smooth user experiences, and battery-conscious performance across a wide device ecosystem.
