Xiaomi Redmi K80
How long will it last?
Our estimateSupported until November 2029 · Buy-by November 2027
Apple doesn't publish an end date, but iPhones have a consistent ~5-year update track record — on that basis the Redmi K80 should be supported until around November 2029. Buying it today still gets you about 3.4 years of safe use (Apple's written legal minimum is 5 years).
