Xiaomi Redmi K70 Ultra
How long will it last?
Our estimateSupported until July 2028 · Buy-by July 2026
Apple doesn't publish an end date, but iPhones have a consistent ~4-year update track record — on that basis the Redmi K70 Ultra should be supported until around July 2028. Buying it today still gets you about 2.1 years of safe use (Apple's written legal minimum is 5 years).
