The Honor 400 Pro takes the standard Honor 400's 200MP camera and adds the three things it lacks: a telephoto lens, flagship-grade water sealing and much faster charging. It runs the Snapdragon 8 Gen 3, a former flagship chip, at an upper-mid-range position.
400 Pro: Display
The 6.7-inch AMOLED runs at 120Hz with a 1280 x 2800 resolution, 3840Hz PWM dimming and a measured 1,481 nits of maximum brightness in GSMArena's lab test. The 5,000-nit peak figure applies to HDR content.
As on the standard 400, protection is quoted only as Mohs level 4 hardness, which is soft for a phone at this level.
400 Pro: Camera
The triple camera pairs the 200MP f/1.9 stabilised main sensor with a 50MP telephoto offering 3x optical zoom and OIS, plus a 12MP autofocus ultrawide; the front carries a dual 50MP and depth-sensor setup. That stabilised 3x zoom is the single biggest photographic advantage over the standard 400.
Video tops out at 4K, and there is no higher frame-rate 4K option listed, so moving-image capability trails the stills hardware.
400 Pro: Battery
UK and European units carry a 5,300mAh silicon-carbon battery; other markets get 6,000mAh. Charging is the headline: 100W wired reaches 51% in 15 minutes and full in 39, with 50W wireless alongside, and GSMArena's active use score came in at 13:54 hours.
That endurance beats the standard 400's 12:29 hours but sits well behind the 19:07 hours of Honor's own Magic8 Pro, so this is not the endurance champion of the range.
400 Pro: Size, Weight and Build
At 160.8 x 76.1 x 8.1mm and 205g with glass on both faces and IP68 plus IP69 sealing, the 400 Pro is built to a clearly higher standard than the standard 400, in Midnight Black, Lunar Grey and Tidal Blue.
The frame is plastic rather than aluminium, an economy most rivals at this level have stopped making, and 205g is a noticeable 21g up on the standard model.
400 Pro: Performance
The Snapdragon 8 Gen 3 with 12GB of RAM delivers genuine flagship-class speed from the previous generation, and Honor commits to up to six major Android upgrades from Android 15, a window still in its early years.
The chip is now two generations behind Qualcomm's newest silicon, and the USB-C port runs at USB 2.0 speeds, slow for a phone pitched at power users.
400 Pro: Who Should Buy
Buy the 400 Pro if you want the most camera for your money below true flagship prices: the 200MP main sensor plus stabilised 3x zoom is a combination nothing else near it matches. Buyers who do not need the telephoto or 100W charging save real money with the standard Honor 400 and give up less than the spec sheets suggest.
