iOS 26 Compatibility: Supported Devices, Issues & Upgrade Tips

Part 1. Officially Supported Devices for iOS 26 (Confirmed by Apple)

Here's a detailed iOS 26 compatibility table based on Apple's confirmed support list:

Part 2. Hot from WWDC 2025 & Developer Beta Insights

Apple announced iOS 26 at WWDC on June 9, 2025, with Liquid Glass updates and "Apple Intelligence" AI upgrades. Liquid Glass, inspired by visionOS, provides iPhone, iPad, and Mac users with an immersive visual style featuring fluid animations and the largest interface upgrade since iOS 7.

Developer beta users have had access to customized widgets, Live Translation in FaceTime, enhanced iMessage capabilities, including polls and translation, and a smarter Phone app with call screening since early June. Apple is scheduled to release the public beta in July, with full rollout approaching the iPhone 17 launch in September.

Early testers report some issues:

• UI lag and overheating on older devices.
• "Reduce Transparency" helps with reading issues caused by excessive transparency.
• Expect occasional setup failures and significant storage needs (~15 GB free space).

Part 3. Top Compatibility Risks & Current Reported Beta Issues

Initial testers, mostly from Developer Beta 1 and internet forums, reported the following issues:

1. Performance Issues & Overheating:

• Users of iPhone 11/12 may suffer jerky animations, while iPhone 16 Pro devices may overheat.
• Reddit user reported "phone is getting warm." on Pro Max.
• The "Liquid Glass" design may produce clutter, such as translucent Control Center and distracting overlays.

2. Feature Gaps:

• Prior iPhone models, such as iPhone 14, lack Apple Intelligence (on-device AI).
• The new "Reduce Transparency" option enhances UI readability by reducing excessive transparency.

3. Installation Failures:

Users encounter server-side issues and restricted capacity (<15 GB required), resulting in update and download failures, as well as "Unable to Check for Update" warnings.

4. Rapid Battery Drain:

• Reports suggest significant battery drain on devices with <80% battery health and during post-installation optimization.
• Apple acknowledges Beta 1.5 battery degradation.

5. App Compatibility Issues:

Banking and security apps may crash or not launch. Some financial applications fail to launch, according to one customer.

Performance & Stability Reports:

While iOS 26 featured innovative improvements, early adopters noted substantial performance concerns. During device indexing and optimization, users have reported overheating, extreme latency, and slow animations, especially following upgrades.

Reports indicate widespread difficulties like:

• Complete system sluggishness after update—responsive only after sleeping or restarting.
• Battery drains rapidly during and after installation. The upgrade reduced one user's iPhone battery usage from 78% to under 30% in under 30 minutes.
• The iPhone 15 and 16 had charging slowdowns during the early upgrade cycle. Apple published an updated beta to solve major battery drain and startup failures.

Should You Upgrade to iOS 26?

Installing iOS 26 on an iPhone 13 or newer is safe and encouraged. These devices support Apple Intelligence and Liquid Glass UI with minimum performance loss. Be cautious with older iPhone SE (2nd Gen), iPhone 11, and iPhone X devices. You may encounter slower performance, shorter battery life, or missing features. Consider pros and cons. Dr.Fone – System Repair (iOS) allows iOS upgrading and downgrading, making iOS 26 testing safer.

Part 4. How-To: Check if Your Device is Compatible with iOS 26

Ensure your iPhone or iPad supports iOS 26 before updating. How to check:

1. Settings Check

The best way to verify if your phone supports iOS 26 is to check under the Settings menu.

Step 1. Open "Settings > General > Software Update."

Step 2. Your device is supported if iOS 26 is available. If not, then your model may not have the A13 chip or the update.

2. Model Identification

Identify your model for certainty:

Step 1. Go to "Settings > General > About > Model Name."

Step 2. Check Apple's iOS 26 supported devices list. iPhone 11 or later (or iPhone SE 2nd gen and after) is certainly secure.

3. Chip Confirmation

Your device's chip determines iOS 26 compatibility.

• The A13+ processor powers iPhones 11 and above.
• The iPhone 12 series and onwards support A14 and beyond for greater performance and Apple Intelligence support.

Part 5. How to Prepare for iOS 26

To minimize issues, crashes, and data loss, prepare your device before updating to iOS 26. A seamless upgrade requires planning.

1. First, back up your iPhone. Finder (macOS), iTunes (Windows), or iCloud (Settings > [Your Name] > iCloud > iCloud Backup > Back Up Now) can back up your machine. This protects your data in a calamity.
2. Clean storage. For major updates, Apple recommends 10GB of free space. Remove unnecessary programs, pictures, and large files.
3. Charge your phone and connect to a reliable Wi-Fi network. Prevent cellular data updates to avoid interruptions and avoid incurring additional charges.
4. Check battery condition in "Settings > Battery > Battery status & Charging." Replacement is suggested if the battery is below 80%, as older batteries may struggle with the new operating system.
5. To address visibility issues, update applications from the App Store and select Reduce Transparency under Accessibility.

Pro Tip: Try Dr.Fone – System Repair to solve system problems first. Install the program, connect your device, and follow "System Repair" to avoid stopped updates and boot loops.
