Design and Build Quality
The Honor 400 has a clean and modern look. It measures 156.5 x 74.6 x 7.3 mm, which makes it slim and easy to hold in one hand. At just 184 grams, it does not feel heavy even after long periods of use.
The phone uses a glass front with a plastic frame and plastic back. While a glass back would have felt more premium, the plastic back keeps the weight down and makes the phone more durable against everyday bumps and drops.
Water and Dust Resistance
One of the standout features of the Honor 400 is its IP65 and IP66 rating. This means the phone is protected against both dust and water jets — whether they are low pressure or high pressure. So if you accidentally get caught in the rain or spill a drink on your phone, you do not need to panic. (Please note that availability of this rating may vary depending on your region.)
The SIM tray supports Nano-SIM + Nano-SIM + eSIM, giving you great flexibility in how you manage your connections. You can use two physical SIMs or swap one for an eSIM, depending on your needs.
Overall, the Honor 400 has a slim, stylish design that looks good and feels sturdy. It is a phone that does not draw too much attention but still looks polished and well-made.
Display
The Honor 400 comes with a 6.55-inch AMOLED display, and it is one of the best screens you will find at this level. The display supports 1B colors, which means colors look natural, deep, and vibrant in every situation.
Refresh Rate and Smoothness
The screen refreshes at 120Hz, which makes scrolling through apps, browsing social media, and playing games feel incredibly smooth. You will notice the difference right away, especially if you are upgrading from a 60Hz screen.
The display also uses 3840Hz PWM dimming, which is great news for people who are sensitive to screen flicker. It reduces eye strain, especially when you use the phone at low brightness levels in the dark.
Brightness and HDR
The peak brightness reaches an impressive 5000 nits, which sounds almost unbelievably high — and it is. In real-world tests, the screen measured around 1550 nits, which is still excellent for outdoor use. You can easily read the screen even in direct sunlight.
The Honor 400 also supports HDR content, so your videos and photos will look more vivid and detailed. The screen resolution is 1264 x 2736 pixels with a pixel density of around 460 ppi, meaning text and images look sharp and clear.
The 90.3% screen-to-body ratio gives you more screen and less bezel, making everything you watch and read feel more immersive.
Performance
Under the hood, the Honor 400 is powered by the Qualcomm Snapdragon 7 Gen 3 chipset, built on a 4nm manufacturing process. This is a capable processor that handles everyday tasks, gaming, multitasking, and more without breaking a sweat.
CPU and GPU
The octa-core CPU features a prime core running at 2.63 GHz, three performance cores at 2.4 GHz, and four efficiency cores at 1.8 GHz. This combination ensures that demanding apps run fast while background tasks use less power to save battery.
The Adreno 720 GPU handles graphics well. Whether you are playing casual games or more graphically demanding titles, the phone handles them smoothly. The 3DMark Wild Life Extreme score of 1492 confirms that it is a solid performer for mobile gaming.

RAM and Storage
The Honor 400 is available with up to 12GB of RAM and up to 512GB of internal storage. This is more than enough space for apps, photos, videos, and music. However, note that there is no memory card slot, so you will need to choose a variant with enough storage for your needs upfront.
In benchmark tests, the phone scored 864,286 on AnTuTu v10 and 3198 on Geekbench v6, which places it comfortably among capable mid-range devices available today.
Camera
The camera system on the Honor 400 is arguably its biggest selling point. The phone features a dual rear camera setup with a headline-grabbing 200MP main sensor.
Main Camera
The primary camera is a 200MP sensor with an f/1.9 aperture, a 1/1.4-inch sensor size, and Optical Image Stabilization (OIS). This is a large sensor for a phone at this level, and it means you can capture a lot of light and detail. Photos taken in daylight look sharp and full of color. The OIS helps reduce blur when you are shooting handheld or in low light.
The secondary camera is a 12MP ultrawide lens with a 112-degree field of view and autofocus. This is great for landscape shots, group photos, and capturing more of your surroundings when a regular shot just does not fit everything in.
Video Recording
The Honor 400 can shoot 4K video with both gyro-EIS (Electronic Image Stabilization) and OIS. This dual stabilization makes your videos look steady and professional. You can also shoot 1080p videos, which are great for sharing on social media.
Selfie Camera
The front camera is a 50MP shooter with an f/2.0 aperture and 4K video recording capability. This is an excellent selfie camera — the high resolution means your selfies will look sharp and detailed, and the video quality is great for video calls and short clips.
Overall, the Honor 400 delivers a strong camera experience. The 200MP sensor is not just a marketing number — it genuinely captures impressive detail, especially in good lighting conditions.
Battery and Charging
The Honor 400 comes in two battery variants depending on your region.
If you are in Europe, you get a 5300mAh battery with 66W wired fast charging. This can charge 44% of the battery in just 15 minutes and reach 100% in about 46 minutes. That is fast enough to top up your phone during a short break.
For other regions (rest of the world), the battery is even larger at 6000mAh, with 80W wired fast charging. This can charge 40% in 15 minutes, which is extremely quick for a battery this size.
Both versions also support 5W reverse wired charging, so you can use your Honor 400 to charge other devices like wireless earbuds in a pinch.
In real-world use, the battery lasts for about 12 hours and 29 minutes of active use, according to testing. For most users, this means the phone will easily last a full day, and possibly into the second day with light to moderate usage.
Software and Features
The Honor 400 runs on Android 15 out of the box, paired with Honor's own MagicOS 9 on top. MagicOS adds a variety of useful features and customization options to the standard Android experience.
One of the most exciting things about the software side of the Honor 400 is the update promise: Honor offers up to 6 major Android upgrades, which means this phone could potentially receive updates all the way to Android 21. That is a long software support window and a strong commitment to keeping your phone relevant for years to come.
MagicOS 9 is generally smooth and well-designed. It offers a clean interface with useful features built in, and it does not feel overly cluttered.
Connectivity and Other Features
The Honor 400 is well-equipped when it comes to connectivity.
It supports 5G (both SA and NSA modes), so you can take full advantage of fast mobile internet where it is available. It also supports 4G LTE, 3G, and 2G networks for broader coverage.
For wireless connectivity, the phone includes Wi-Fi 6 (802.11 a/b/g/n/ac/6) with dual-band support and Wi-Fi Direct. This means faster and more reliable wireless internet compared to older Wi-Fi standards.
Bluetooth 5.4 with aptX HD support ensures high-quality wireless audio for your headphones and earbuds.
The phone supports multiple satellite navigation systems including GPS, GLONASS, GALILEO, QZSS, and BDS, giving you accurate location tracking almost anywhere in the world.
Other noteworthy features include:
NFC for contactless payments and quick pairing
Infrared port to control your TV, AC, and other home appliances
Under-display optical fingerprint sensor for fast and secure unlocking
USB Type-C 2.0 with OTG support
Stereo speakers with a very good loudness score of -25.8 LUFS
One missing feature is a 3.5mm headphone jack, so you will need wireless headphones or a USB-C adapter for wired audio. There is also no FM radio.
