Xiaomi Redmi Note 9S
How long will it last?
Our estimateSupported until April 2023 · Buy-by April 2021
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Redmi Note 9S should be supported until around April 2023. Buying it today still gets you about -3.2 years of safe use (Apple's written legal minimum is 5 years).
