Apple iPhone XS
How long will it last?
Our estimateSupported until September 2027 · Buy-by September 2025
Apple doesn't publish an end date, but iPhones have a consistent ~8-year update track record — on that basis the iPhone XS should be supported until around September 2027. Buying it today still gets you about 1.2 years of safe use (Apple's written legal minimum is 5 years).

Frequently asked questions
How long will the iPhone XS get updates?
It supports iOS 18 and is still receiving security updates in 2026. With no formal Apple policy, history suggests patches should continue into roughly 2027.
What is the difference between the iPhone XS and XS Max?
They are nearly identical in chip, cameras and software. The XS has a smaller 5.8-inch screen and lighter body, while the XS Max has a 6.5-inch display and a larger battery.
Should I replace the battery on a used iPhone XS?
Often yes. The 2658 mAh battery is small by modern standards and most units are years old, so a battery replacement greatly improves daily usability.
