Xiaomi Redmi Turbo 4
How long will it last?
Our estimateSupported until January 2029 · Buy-by January 2027
Apple doesn't publish an end date, but iPhones have a consistent ~4-year update track record — on that basis the Redmi Turbo 4 should be supported until around January 2029. Buying it today still gets you about 2.5 years of safe use (Apple's written legal minimum is 5 years).
