Oppo A3x 4G
How long will it last?
Our estimateSupported until August 2027 · Buy-by August 2025
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the A3x 4G should be supported until around August 2027. Buying it today still gets you about 1.2 years of safe use (Apple's written legal minimum is 5 years).
