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.
PROs
compact, fast SD 8 Elite Gen 5 with UFS 4.1 performance, 48hr endurance from 7000mAh (6330mAh in EU) battery with sub-50min 100W charging (50W wireless). 460ppi LTPO AMOLED screen with Dolby Vision and >2100 PWM dimming, IP68 protection. excellent photo and video recording from a 50MP OIS PDAF main & tele cameras + 50MP ultrawide, great 50MP PDAF selfie, 6 years of OS updates, basic desktop replacement functionality baked into Android 17, fast USB-C 3.2 with Display Port and OTG
CONs
dim >1100nits screen, still no AF on ultrawide camera, no SDmemory, no desktop replacement feature

* TOP Battery Endurance* TOP Software
EDITORIAL: Poco used to stand for "flagship killer" with a combination of excellent performance and lower price. For years, the compromise was the brand and imaging performance. But everything has an end and we're seeing a new Poco now: exceptional endurance, top-tier components with improved imaging and a flagship-level price. While disappointing to many, F9 Ultra is still a phone with a lot.
PROs
flagship build, good SD 8 Elite Gen 5 with UFS 4.1 performance, >42hr endurance from a 8050mAh Si-C battery with sub-60min 100W (50W wireless) charging, ~1250nits 415ppi 185Hz AMOLED screen with Dolby Vision, IP68 protection, very good 200MP 24mm main + 50MP 114mm periscope telephoto (both OIS PDAF) + average 50MP 17mm ultrawide, very good 32MP 22mm selfie, above average video recording (ultrawide spoils the score), feature and connectivity rich OS with 4 years of updates, Android 17's native desktop replacement functionality, fast USB-C 3.2 with video output, Bose branded stereo speaker system with a bass speaker
CONs
bigger (almost 9mm/0.35" thick) and heavier (235g/8.29oz) then F8U, same processor at much higher price (than F8U), non-LTPO with minimal refresh rate variability (mostly 60-120Hz), no AF on ultrawide or selfie, no expandable memory slot, speaker sound could be louder, big price hike
