EDITORIAL: Xiaomi is going after Apple this year with matching gen number and addition of Pro and Pro Max models. Plain 17 adds a massive battery upgrade (from 5500 to 7000mAh, 6330mAh in EU), faster processor and storage, better selfie (finally with AF) and Dolby Atmos certified speakers. It is a battery endurance beast, providing 42+ hours to even a heavy user. Cameras are similar to excellent Xiaomi 15: competent performer with some excellent results. Apple flattery extended to physical design too - while last year's model was one of the nicest to hold because of softly curved front and back glass panels, the 17 has palm-cutting sharp frame with flat front and back.

EDITORIAL: This year, one of the TOP 5 camera phones came with a significant battery endurance improvement. The main camera retained the 1" sensor, lost the variable aperture but the 2 zoom cameras are now better then ever. There is no AF on the selfie and like last year, there is an extra camera grip available for the ultimate photo & video creation. Still missing are SD memory card and the desktop replacement feature. Promised are 4 years of OS updates.
