What the Update Statuses Mean
- Current — your iPhone runs the latest major iOS version and gets new features and security updates.
- Limited — your iPhone no longer gets new major iOS versions, but Apple sometimes still ships critical security-only patches for it.
- End of life — no further updates of any kind. The phone still works, but it no longer receives security fixes.
To see exactly which security fixes each version received, check Apple’s security releases list.
Which iPhones Can Run iOS 27?
Apple released iOS 27 to the public on September 14, 2026. It supports the same iPhones as iOS 26 — the iPhone 11 and later, plus the iPhone SE (2nd generation) and later. If your iPhone ran iOS 26, it can update to iOS 27. You can see what’s new on Apple’s iOS page.
Just updated? A few days of heavier battery use is normal while your iPhone finishes background work. Our iOS 27 battery drain guide covers what’s normal and what to fix. If Settings shows an update still finishing in the background, see Update Finishing in Background iPhone.
How to Update Your iPhone
- Back up your iPhone to iCloud or your computer.
- Plug into power and connect to Wi-Fi.
- Go to Settings → General → Software Update and follow the prompts.
Apple’s step-by-step guide, Update your iPhone or iPad, covers automatic updates and what to do if an update won’t install.
Is Your iPhone Too Old? Upgrade vs. Keep
An iPhone marked Limited or End of life isn’t unusable, but it misses new features and, eventually, security fixes, and some apps stop supporting older iOS versions over time. If your iPhone is still Current but feels slow, the fix is often cheaper than a new phone — check it with our iPhone battery health checker and read our iPhone running slow guide.
