Infinix Note 40S
How long will it last?
Our estimateSupported until October 2027 · Buy-by October 2025
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Note 40S should be supported until around October 2027. Buying it today still gets you about 1.3 years of safe use, and Apple's written legal minimum is 5 years (verified June 2026).

Street price ÷ months of safe use remaining — the number that makes cheap short-lived phones expensive, and well-supported ones cheap.
82% above the under-$300 median ($7.13/mo, dying phones excluded)
Our verdict
A slim, curved-screen Note with surprise wireless charging, but no 5G to match its premium look.
Pros
- Curved 120Hz AMOLED in a light 176g body
- Includes 20W wireless charging, rare at this price
- 108MP main camera for detailed daylight shots
Cons
- 4G-only despite its mid-range positioning
- Helio G99 is capable but not a step up over older Notes
