Xiaomi Redmi 15 5G
How long will it last?
Our estimateSupported until August 2029 · Buy-by August 2027
Apple doesn't publish an end date, but iPhones have a consistent ~4-year update track record — on that basis the Redmi 15 5G should be supported until around August 2029. Buying it today still gets you about 3.1 years of safe use (Apple's written legal minimum is 5 years).
