EDITORIAL: The best Oppo phone of 2024 is a full feature, mature flagship. Outstanding performance, excellent build with a silent-vibrate-ring slider and a new "control button" to start the camera, zoom and take a photo. Feels smaller and easier to hold due to both font and back 4 side micro-curved glass panels. 5 years of very stable OS and a great main camera with 2 zoom lenses but Oppo is saving its best for the X8 Ultra, expected in early 2025. Still no AF on selfie, no memory expansion or desktop replacement software.

PROs
great performance led by Mediatek Dimensity 9400, 2-day battery life of 5910mAh Silicone Carbon battery with 80W wired (50W wireless) fast charging, >1300nits bright LTPO AMOLED screen with Dolby Vision, IP69 protection, 50MP main + two 50MP tele lenses with PDAF and OIS + a 50MP ultrawide with PDAF, great build and a ring-vibrate-off hardware slider
CONs
still big at 76.7mm, a lack of expandable SDmemory storage, no desktop replacement

77.8mm (3.06in) · Oct 23, 2025 · Rank #36

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)
