Oppo K13 5G
How long will it last?
Our estimateSupported until April 2029 · Buy-by April 2027
Apple doesn't publish an end date, but iPhones have a consistent ~4-year update track record — on that basis the K13 5G should be supported until around April 2029. Buying it today still gets you about 2.9 years of safe use, and Apple's written legal minimum is 5 years (verified June 2026).

TrueCost
Street price ÷ months of safe use remaining — the number that makes cheap short-lived phones expensive, and well-supported ones cheap.
14% cheaper than the under-$300 median ($7.13/mo, dying phones excluded)
Our verdict
A battery monster: a 7000mAh cell with 80W charging and full IP68/IP69 sealing make this one of the best endurance-per-dollar phones of 2025.
Pros
- Huge 7000mAh battery delivers exceptional multi-day endurance
- 80W charging keeps that big battery quick to refill
- Comprehensive IP65 through IP69 dust and water resistance
Cons
- Snapdragon 6 Gen 4 is efficient but only mid-tier for gaming
- Camera is effectively single-lens with a filler 2MP depth sensor
