TrueCost
Street price ÷ months of safe use remaining — the number that makes cheap short-lived phones expensive, and well-supported ones cheap.
17% cheaper than the $300–600 median ($11.72/mo, dying phones excluded)
Our verdict
The affordable Leica-camera option with the same big screen and battery as the Pro, minus the periscope and fastest charging.
Pros
- Leica-tuned 50MP main with a handy 50MP 2x telephoto
- Large 6.83-inch 144Hz display and 5500mAh battery for the price
- Lighter at 194g than the Pro while keeping IP68 protection
Cons
- No wireless charging and slower 67W wired charging than the Pro
- Dimensity 8400-Ultra is upper-midrange, not flagship class
