HONOR 400

The HONOR 400 is the standard model of HONOR's 2025 "400" family and the one that most clearly shows what the brand wanted this generation to be about: a very large main sensor, a battery that is bigger than the slim body suggests, and a long list of software tricks built around photo editing. This page works from the published specifications and the manufacturer's own launch material. It covers where the phone sits in the lineup, what the hardware actually offers, and where the compromises are, so you can judge whether the formula suits you.

Where it sits in the lineup

HONOR announced the 400 series in London on 22 May 2025 and put the phones on sale in Europe the same day. In the United Kingdom the HONOR 400 started at £399.99, and in France, Germany, Italy, Spain and other EU markets at €449.90, according to HONOR's launch announcement. No official US price was published, so none is listed here. The standard phone is a step below the HONOR 400 Pro, which uses a Snapdragon 8 Gen 3 chip, adds a 3x telephoto camera, raises the dust and water rating and charges faster, including wirelessly. Further down the range, the HONOR 400 Smart and the HONOR 400 Lite aim at much lower budgets and share only the badge and the general design language. Compared with the older HONOR Magic7 Pro, the 400 is clearly the value option, trading premium materials and extra cameras for a lower asking price.

Design and display

The phone measures 156.5 x 74.6 x 7.3 mm and weighs about 184 g, which is light for a device with a 5300 mAh battery. The back is a single smooth sheet with a rounded camera island that holds two large lens rings and the flash, and the finishes are Midnight Black, Meteor Silver and Desert Gold. HONOR rates the phone IP65, meaning protection against dust and water jets rather than immersion, and notes that water resistance is not permanent. It also quotes a five-star SGS drop-resistance certification for the whole unit. That is a reasonable level for a mid-priced phone, but it sits below the IP68 and IP69 ratings that HONOR gives the Pro.

The screen is a flat 6.55-inch AMOLED panel with a resolution of 2736 x 1264 pixels, about 460 pixels per inch, and a 120Hz refresh rate. HONOR states a peak brightness of 5000 nits, with the footnote that this applies to HDR content in certain scenarios, so outdoor visibility is likely to be good but the headline number should not be read as a sustained figure. The panel covers the DCI-P3 gamut, supports 1.07 billion colours, uses 3840Hz PWM dimming for people sensitive to flicker, and can drop to 1.5 nits in the dark. The selfie camera sits in a small centred punch hole. A flat panel, rather than a strongly curved one, is a practical choice for protectors and cases.

Performance and software

The chipset is the Qualcomm Snapdragon 7 Gen 3, an octa-core part with an Adreno 720 graphics unit. It sits in the upper middle of the market: fast enough for everyday multitasking and for demanding games at medium to high settings, while not matching a flagship chip in sustained load. Memory is 8GB, with 256GB or 512GB of storage; HONOR notes that the usable space is smaller because the system takes a share. There is no mention of a memory card slot, and none is listed.

The phone ships with MagicOS 9.0 based on Android 15. HONOR's software emphasis is on AI features: an eraser for removing passers-by and reflections, outpainting that extends the frame of a photo, a film-simulation mode, image-to-video generation that uses Google's Veo 2 (with a two-month free access offer from the gallery), on-device deepfake detection, Gemini integration and tools for translation, summaries and recording. A motion-sickness relief mode is also included. HONOR does not state a software-update commitment in the material consulted for this page, which matters for anyone planning to keep the phone for years. Connectivity covers 5G, Wi-Fi 6, Bluetooth 5.4, NFC and an infrared remote, with dual stereo speakers and a USB-C port that runs at USB 2.0 speed.

Camera

The headline is the 200MP main camera: a 1/1.4-inch sensor behind an f/1.9 lens with optical stabilisation. By default a sensor like this produces images at a lower resolution that combines many pixels into one, so the main benefit is light-gathering and cropping headroom rather than 200-megapixel files in everyday use. HONOR also promotes "AI Super Zoom", which it describes as a world first for a 30x range from a main camera, using the sensor's resolution and AI processing rather than a dedicated telephoto lens. These are manufacturer claims, and digital zoom from 15x to 30x will always be an estimate of detail rather than a recording of it. The only other rear camera is a 12MP ultra-wide with a 112-degree field of view that HONOR also uses for macro shots.

On the front, the 50MP f/2.0 selfie camera is unusually high-resolution for this class and supports portrait modes. Video recording goes up to 3840 x 2160 pixels. The software side adds a long list of modes: Pro, Night, Aperture, Slow-Mo, Panorama, Film Simulation, Moving Photo and a multi-video mode that records both lenses. In short, the hardware is built around one very good camera, with the second and the front camera as support. If you shoot a lot of subjects at a distance, the lack of a true telephoto is the area where the Pro, or a rival with an optical zoom, will do better.

Battery and charging

The battery is rated at 5300 mAh typical (5170 mAh rated) and uses silicon-carbon chemistry, which packs more energy into the same volume than conventional lithium-ion cells. That is the reason a 7.3 mm phone can carry a capacity that many thicker models do not match. Wired charging reaches 66W with HONOR SuperCharge, and HONOR's own laboratory figure is 44 percent in about 15 minutes. No wireless charging is listed. The company also says the cell should keep more than 80 percent of its health after four years of use. Like all such statements, this is a target under laboratory conditions rather than a guarantee. A charger is not mentioned in the box contents in the specification sheet, which lists the phone, a USB-C cable, a quick-start guide, an eject tool and a warranty card, depending on the market.

Who it is for

The HONOR 400 suits someone who wants a light, thin phone with endurance and a strong main camera at a price clearly below the big flagships. It is a good fit for people who edit photos on the phone and enjoy AI tools, for heavy users who need a day and a half of battery life, and for those who like a flat screen. Readers looking at the same price band may want to compare it with the Samsung Galaxy A56, which offers a different balance of display, software support and camera hardware; the side-by-side view is at HONOR 400 vs Galaxy A56. The newer HONOR 600 is also worth a look if you prefer to see what the brand did next.

Compromises

There are several. The IP65 rating is lower than IP68, so the phone is not meant for submersion. There is no telephoto lens, no wireless charging and the USB port is USB 2.0. HONOR gives no update policy in the sources used here. The 5000-nit figure applies only in limited scenarios. The AI extras, and especially the generative video tool, depend on an internet connection and on offers that can change by market. Finally, the 200MP label should be understood as a way to raise quality through pixel combining, not as a promise of enormous files. Taken together, the HONOR 400 is a well-rounded phone with a few clear strengths, and its limits are those you would expect from a model at this price.
