* TOP Photography

EDITORIAL: Ten months since last Xiaomi’s Ultra comes a phone with the first-ever physical zoom ring. 17 Ultra Leica edition features a physical zoom ring, ribbed frame for better grip, encryption chip and dual satellite communication chops that plain 17 Ultra lacks. Both models loose one of the two telephoto lenses 15 Ultra had and their screens drop below 500ppi. The phones gained in width and battery size but their photography skills are better then ever. SUPERPOWER: this is the TOP 5 photo phone in the world

EDITORIAL: (this is a pre-test listing based on reasonable expectations of processor, battery, charging, screen, imaging and software performance) A true flagship phone from Redmi brings a spec-fest: world’s best processor, 7500mAh battery with fast charging, big and bright Dolby Vision screen, Dolby Atmos and Bose tuned stereo sound, triple 50MP back cameras, ultrasonic authentication and a flagship grade Display-Out USB-C port – all for half the price of iPhone 17PM or A25U (at lounch). Naturally, there are compromises on performance speed, imaging and software fronts.

PROs
flagship built, great SD 8 Elite Gen 5 with UFS 4.1 performance, 2day endurance from 7500mAp Si-C battery with sub-60min 100W (50W wireless) charging, bright >410ppi LTPO AMOLED screen with Dolby Vision,. IP68 protection, good imaging from 50MP main + 50MP 5x periscope telephoto (both with OIS PDAF) + 50MP ultrawide, 6 years of OS updates and a fast USB-C port with Display Out tech and OTG
CONs
big and hard to use one-hand, uneven ultrawide and selfie performance, no SDmemory slot, only basic desktop replacement functionality (added Oct 25, 2025)
