Infinix Note 40
How long will it last?
Our estimateSupported until March 2027 · Buy-by March 2025
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Note 40 should be supported until around March 2027. Buying it today still gets you about 0.8 years of safe use (Apple's written legal minimum is 5 years).
