Tecno Spark 40 5G
How long will it last?
Our estimateSupported until August 2028 · Buy-by August 2026
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Spark 40 5G should be supported until around August 2028. Buying it today still gets you about 2.2 years of safe use (Apple's written legal minimum is 5 years).
