Apple’s next major iPhone software update is expected to raise a familiar question for many users: which iPhone models will support iOS 27? Because iOS 27 has not been fully detailed publicly, any compatibility guide should be read as an informed explanation based on Apple’s recent support patterns, chip requirements, and previous upgrade cycles. Still, the likely picture is clear enough for owners to understand whether their current iPhone may be ready for the next generation of iOS.
TLDR: iOS 27 is expected to support newer iPhone models with modern Apple silicon, especially devices from the iPhone 12 series and later. Older models such as the iPhone 11 family and iPhone SE 2nd generation may be at risk if Apple raises the minimum hardware requirement. The iPhone SE 3rd generation, iPhone 13 series, iPhone 14 series, iPhone 15 series, iPhone 16 series, and newer models are expected to have a much stronger chance of compatibility. Final confirmation will depend on Apple’s official iOS 27 supported devices list.
Understanding iOS 27 Compatibility
iOS compatibility is determined by more than the age of an iPhone. Apple considers the device’s processor, memory, graphics capability, Neural Engine performance, security hardware, battery efficiency, and the ability to run new system features smoothly. A device may still feel fast for everyday use, but it may not meet the technical requirements for the newest version of iOS.
With each major iOS release, Apple usually supports iPhones for many years. This long support window is one of the strongest advantages of the iPhone ecosystem. However, every few years, older models are removed from the supported list when the software begins to require more advanced hardware.
For iOS 27, the most important hardware factor is expected to be the Apple A series chip. Devices with newer chips are more likely to receive the update, while older models with less memory and weaker neural processing may face limitations or be excluded completely.
Expected iPhone Models That May Support iOS 27
The following list reflects the iPhone models that are most likely to support iOS 27, based on current Apple support trends and hardware capability. Apple’s final list may differ, but these models have the strongest chance.
- iPhone 18 series and newer launch models, if released alongside iOS 27
- iPhone 17 series
- iPhone 16 series, including iPhone 16, 16 Plus, 16 Pro, 16 Pro Max, and related models
- iPhone 16e, if positioned as a current budget model
- iPhone 15 series, including iPhone 15, 15 Plus, 15 Pro, and 15 Pro Max
- iPhone 14 series, including iPhone 14, 14 Plus, 14 Pro, and 14 Pro Max
- iPhone 13 series, including iPhone 13 mini, 13, 13 Pro, and 13 Pro Max
- iPhone SE 3rd generation
- iPhone 12 series, including iPhone 12 mini, 12, 12 Pro, and 12 Pro Max
The iPhone 12 series is likely to be the most important borderline group. If Apple keeps support broad, these models may remain eligible for iOS 27. If Apple decides to raise the hardware floor, the iPhone 12 family could be the oldest supported generation or could become the first major group to lose eligibility.
Models That May Be at Risk
Several older devices may be considered at risk for iOS 27 compatibility. These models are still capable phones for calls, messaging, browsing, and apps, but they may not meet the expected performance target for Apple’s newest system features.
- iPhone 11
- iPhone 11 Pro
- iPhone 11 Pro Max
- iPhone SE 2nd generation
These devices use the A13 Bionic chip, which has aged well, but Apple may decide that iOS 27 requires newer hardware. If features related to artificial intelligence, on-device processing, advanced camera tools, or background system intelligence become central to iOS 27, the A13 generation could be left behind.
It is also possible that Apple may provide partial support, where some devices receive iOS 27 but miss certain advanced features. This has happened before with features that require newer processors, LiDAR sensors, larger memory capacity, or Pro-level camera systems.
Why Apple Drops Older iPhone Models
When an older iPhone is no longer supported, it is usually not because Apple wants to make the device unusable. Instead, the company must balance stability, security, battery life, and feature performance. A major iOS update affects the entire system, from the lock screen and notifications to apps, privacy controls, wireless connectivity, and background services.
Older iPhones often have less RAM, slower storage, older modems, and lower graphics capacity. As iOS becomes more advanced, these limitations become more noticeable. Apple may choose to stop major upgrades on a device to avoid a poor user experience.
Performance consistency is also important. Apple prefers an update to feel polished across supported devices. If an older iPhone can technically run the software but struggles with animation smoothness, multitasking, or battery drain, Apple may exclude it from the major update list.
Feature Support May Vary by Model
Even if an iPhone receives iOS 27, it may not receive every iOS 27 feature. This distinction is important. Compatibility means the device can install and run the operating system, but feature availability depends on hardware.
For example, newer iPhones may receive more advanced Apple Intelligence features, improved image processing tools, upgraded Siri functions, and enhanced privacy features that rely on powerful on-device processing. Older supported devices may receive the core interface, security improvements, app updates, and general system refinements, but not the most demanding capabilities.
Pro models may also receive exclusive features tied to camera hardware, display technology, or LiDAR. An iPhone 15 Pro or iPhone 16 Pro may support functions that an iPhone 13 or iPhone SE cannot, even when both run the same iOS version.
Most Likely Fully Supported Devices
The iPhones most likely to receive the best iOS 27 experience are newer models with strong processors and more memory. These devices should be better prepared for demanding features and long-term app support.
- iPhone 18 series: Expected to launch with iOS 27 or be directly optimized for it.
- iPhone 17 series: Likely to support nearly all major iOS 27 features.
- iPhone 16 Pro and 16 Pro Max: Strong candidates for advanced AI, camera, and performance features.
- iPhone 15 Pro and 15 Pro Max: Still expected to remain highly capable for demanding iOS features.
- iPhone 16 and 16 Plus: Likely to receive broad feature support, depending on hardware segmentation.
These models should also remain strong choices for users planning to keep an iPhone for several more years. A newer chip gives the device a better chance of receiving not only iOS 27, but also future updates beyond it.
What About the iPhone SE?
The iPhone SE line can be slightly harder to judge because it often combines an older design with a newer chip. The iPhone SE 3rd generation, powered by the A15 Bionic chip, has a better chance of supporting iOS 27 than the iPhone SE 2nd generation, which uses the A13 Bionic chip.
However, the SE models may still miss certain features due to smaller displays, single-camera systems, and older hardware components. They may receive the main iOS 27 update while lacking some visual, camera, or intelligence-based tools available on newer full-screen iPhones.
How to Check an iPhone Model
Before deciding whether an upgrade is necessary, an owner should first identify the exact iPhone model. This can be done directly from the device settings.
- Open Settings.
- Select General.
- Tap About.
- Check the Model Name and Model Number.
This information helps determine whether the device belongs to a likely supported generation or an at-risk generation. It is also useful when checking Apple’s official compatibility page after iOS 27 is announced.
Should an Older iPhone Be Upgraded Before iOS 27?
An iPhone owner does not necessarily need to replace a device only because iOS 27 is approaching. If the phone still receives security updates, runs essential apps, and has acceptable battery life, it can remain useful. However, anyone using an iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, or iPhone SE 2nd generation may want to prepare for the possibility that iOS 27 will not be available.
A battery replacement may extend the life of an older iPhone, but it will not change software eligibility. For users who want the longest update window, a newer model such as an iPhone 15, iPhone 16, or later device would be a safer investment.
What Happens If an iPhone Does Not Support iOS 27?
If an iPhone does not support iOS 27, it does not stop working. The device can continue using its current iOS version, installed apps, photos, messages, and core services. Over time, however, some apps may require newer iOS versions, and certain security updates may become less frequent.
Banking apps, productivity tools, smart home apps, and social media platforms may eventually end support for older iOS versions. This process usually happens gradually, so an unsupported iPhone can often remain useful for a while, especially as a backup phone or secondary device.
Final Thoughts
iOS 27 compatibility will likely follow Apple’s familiar pattern: newer iPhones will get the broadest support, mid-generation models will remain safe, and older devices will sit on the edge of eligibility. The iPhone 12 series and newer models appear to have the best chance, while the iPhone 11 family and iPhone SE 2nd generation may be the most vulnerable.
Until Apple confirms the official supported devices list, the smartest approach is to treat all predictions as guidance rather than certainty. Still, the general rule is simple: the newer the chip, the better the odds of running iOS 27 smoothly and receiving its most advanced features.
