What About Older iPhones?
Unfortunately, devices older than the iPhone 12 series are unlikely to receive iOS 27. This means the following models will probably remain on iOS 26 as their final supported version:
- iPhone 11 and iPhone 11 Pro series (2019)
- iPhone XS and XR series (2018)
- iPhone X (2017)
- iPhone 8 and 8 Plus (2017)
Apple makes these decisions based on hardware capabilities, processor performance, and RAM limitations. Older devices simply lack the computational power to run newer iOS versions efficiently while maintaining a good user experience.
What We Expect from iOS 27
While specific features haven’t been announced, we can make educated predictions based on Apple’s recent focus areas and industry trends:
Enhanced AI Integration
Following the introduction of Apple Intelligence in iOS 18, we anticipate iOS 27 will expand these capabilities significantly. Expect deeper integration of on-device machine learning, improved Siri functionality, and smarter suggestions across the operating system. However, the most advanced AI features will likely require iPhone 15 Pro or newer models with sufficient processing power. (INTERNAL LINK: Apple Intelligence Features Guide)
Privacy and Security Enhancements
Apple has consistently prioritized user privacy, and iOS 27 should continue this tradition with new privacy controls, enhanced app tracking transparency, and additional security features. These improvements typically work across all supported devices.
Performance Optimizations
Each iOS release brings under-the-hood improvements that enhance battery life, reduce memory usage, and improve overall system responsiveness. These optimizations help ensure older devices like the iPhone 12 can continue running the latest software acceptably.
New Customization Options
Following iOS 18’s expanded customization features, iOS 27 will likely offer users even more control over their home screen appearance, lock screen functionality, and Control Center layout. These visual enhancements usually work well across all compatible devices.
Should You Upgrade to iOS 27?
The decision to upgrade depends on several factors:
If you have an iPhone 15 or newer: Absolutely upgrade. You’ll get the full iOS 27 experience with all features enabled and optimal performance.
If you have an iPhone 13 or 14: Yes, upgrade. These devices have the hardware to run iOS 27 smoothly, though you might miss out on a few Pro-exclusive features.
If you have an iPhone 12: Consider waiting a few weeks after the initial release to see how other iPhone 12 users report their experience. While your device will support iOS 27, performance might not be quite as snappy as on newer models.
How to Prepare for iOS 27
Back Up Your Device
Before any major iOS update, always create a complete backup of your iPhone. You can back up to iCloud or your computer using Finder (macOS) or iTunes (Windows). This ensures you won’t lose any data if something goes wrong during installation. (INTERNAL LINK: How to Back Up Your iPhone)
Check Storage Space
iOS updates require significant free storage space for download and installation. Make sure you have at least 5-8 GB of available storage before attempting to update. Delete unused apps, photos, or videos if necessary.
Update Your Apps
In the weeks following iOS 27’s release, app developers will push updates to ensure compatibility. Keep your apps updated to avoid crashes or functionality issues on the new operating system.
Read the Release Notes
When iOS 27 becomes available, take time to read through Apple’s release notes and feature descriptions. Understanding what’s new helps you take full advantage of the update and avoid surprises.
Beta Testing Considerations
If you’re thinking about installing the iOS 27 beta when it becomes available in June or July 2026, keep these points in mind:
Beta Software is Unstable
Beta releases contain bugs, performance issues, and incomplete features. Your iPhone might experience app crashes, battery drain, or unexpected behavior. Never install beta software on a device you rely on daily for work or important communications.
You Can’t Easily Downgrade
While it’s possible to downgrade from a beta to the current stable iOS version, the process is complicated and requires a computer. You’ll also lose any data created after installing the beta unless you have a backup from before the beta installation. (INTERNAL LINK: How to Downgrade from iOS Beta)
Third-Party Apps May Not Work
App developers need time to update their applications for new iOS versions. During the beta period, some of your favorite apps might crash, function incorrectly, or not work at all.
Providing Feedback is Important
If you do install the beta, use the Feedback app to report bugs and issues to Apple. Your feedback helps improve the final release for everyone.
Historical Context: Apple’s Support Pattern
Looking at Apple’s track record helps us understand why we’re confident about iOS 27 device compatibility. The company has maintained a fairly predictable pattern:
iOS 18 dropped support for the iPhone 8, 8 Plus, and iPhone X, which were released in 2017. This gave those devices six years of software support.
iOS 26 is expected to continue supporting devices back to the iPhone 11 series (2019), giving those models six to seven years of updates.
Following this pattern, iOS 27 supporting devices back to the iPhone 12 (2020) provides six years of software support, consistent with Apple’s recent approach.
This extended support period is one reason iPhones retain their value longer than most Android devices and why many users feel comfortable keeping their iPhones for four to five years or more.
Beyond Device Compatibility: Feature Availability
It’s worth noting that device compatibility doesn’t guarantee access to every feature. Apple increasingly restricts certain capabilities to newer devices with specific hardware requirements:
Processor-Dependent Features
Advanced computational photography, real-time translation, and complex AI operations often require the latest A-series or even M-series chips. The iPhone 12’s A14 Bionic, while still capable, might not support iOS 27’s most demanding features.
RAM Limitations
Memory-intensive features like advanced multitasking or extensive background processing might be limited on older devices with less RAM. The iPhone 12 has 4GB of RAM, while newer Pro models have 8GB or more.
Camera and Sensor Requirements
Features leveraging LiDAR sensors, advanced camera systems, or specific sensor capabilities won’t work on devices lacking that hardware. The iPhone 12 and 12 mini, for instance, don’t have LiDAR, which some features might require.
Conclusion
iOS 27 represents the next evolution of Apple’s mobile operating system, expected to arrive in September 2026 following its traditional development and beta testing cycle. iPhone users with devices from the iPhone 12 onwards should anticipate receiving this update, though the experience will vary based on device capabilities.
The June 2026 developer beta and July 2026 public beta will give us our first real look at what Apple has planned. Until then, all information remains speculative based on historical patterns and industry analysis.
Whether you’re excited about new features or simply want to ensure your current iPhone remains supported, understanding the expected timeline and device compatibility helps you plan accordingly. Remember to back up your data before any major update and consider your device’s age when deciding whether to upgrade immediately or wait for initial bugs to be resolved.
