Infinix Smart 9
How long will it last?
Our estimateSupported until September 2026 · Buy-by September 2024
Apple doesn't publish an end date, but iPhones have a consistent ~2-year update track record — on that basis the Smart 9 should be supported until around September 2026. Buying it today still gets you about 0.3 years of safe use (Apple's written legal minimum is 5 years).
