Question: My iPhone won't get iOS 27. How long can I keep using it safely?
A
Answer: Yes, for now, as long as it's on the newest version it can run. iOS 27 supports the iPhone 11 and newer, plus the iPhone SE (2nd generation), which is the same list as iOS 26. Older iPhones still get security fixes on their last version: Apple released iOS 18.7.10 for the iPhone XS and XR on August 17, 2026, and fixes for iPhone 6s through X in May 2026. The risk grows each year, so treat an iPhone XS or older as a phone to replace within the next year or so, not today.
