Cat S53
How long will it last?
Our estimateSupported until July 2025 · Buy-by July 2023
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the S53 should be supported until around July 2025. Buying it today still gets you about -0.9 years of safe use, and Apple's written legal minimum is 5 years (verified June 2026).

- Adds 5G that earlier Cat rugged models lacked
Cons
- Very heavy 320g with only an HD+ display
- Support is estimated to have ended around 2025 after Bullitt's restructuring
