Whenever Apple announces a major iOS release, a primary concern in the secondary mobile market is which Apple iPhone models will continue to receive updates. Software compatibility affects device longevity, very important trade-in value, refurbishment prioritisation and the decisions of fleet managers and enterprise buyers.
Expected compatibility list
Based on device age and chipset generations, the Apple iPhone models most likely to receive iOS 27 include the
- Apple iPhone 17, Apple iPhone 17 Pro and Apple iPhone 17 Pro Max launched in 2025
- Apple iPhone Air launched in 2025
- Apple iPhone 16e launched in 2025
- Apple iPhone 16, Apple iPhone 16 Plus, Apple iPhone 16 Pro and Apple iPhone 16 Pro Max launched in 2024
- Apple iPhone 15, Apple iPhone 15 Plus, Apple iPhone 15 Pro and Apple iPhone 15 Pro Max launched in 2023
- Apple iPhone 14, Apple iPhone 14 Plus, Apple iPhone 14 Pro and Apple iPhone 14 Pro Max launched in 2022
- Apple iPhone SE 3 launched in 2022
- Apple iPhone 13, Apple iPhone 13 mini, Apple iPhone 13 Pro and Apple iPhone 13 Pro Max launched in 2021
- Apple iPhone 12, Apple iPhone 12 mini, Apple iPhone 12 Pro and Apple iPhone 12 Pro Max launched in 2020
- Apple iPhone SE 2 launched in 2020
- Apple iPhone 11, Apple iPhone 11 Pro and Apple iPhone 11 Pro Max launched in 2019
How Apple decides support
Processor generation is the decisive factor in whether a model receives an iOS update. Apple typically supports devices for at least five years after launch, with exceptions when a chipset remains widely used across product lines. Device popularity and distribution also influence support decisions because large install bases make extended compatibility more practical.
Implications for refurbishment
For refurbishers and resellers of used products, devices that remain on the compatibility list retain value for longer. Models with A13 and newer chips are likely to be safe for another year, while devices built on A12 silicon face greater uncertainty. The Apple iPhone SE 2 and Apple iPhone 11 are notable borderline cases because of their chipsets and RAM configurations.
Practical guidance for the market
Secondary market actors should prioritise inventory that aligns with expected support. Testing for performance under Apple iOS 26 updates can indicate how devices will fare with iOS 27, especially where RAM constraints are evident. Clear communication with buyers about likely future update eligibility will help manage expectations and preserve trust.
What to watch next
Final compatibility will be confirmed by Apple at its iOS 27 announcement. Until then, industry participants should base planning on chipset family, device age and observed performance under current Apple iOS releases.
