Honor 400 5G

The Honor 400 5G has a standard, non-folding form factor measuring 156.5 mm tall, 74.6 mm wide, and just 7.3 mm thick, with a total volume of 85.23 cm³ and a weight of 184 g. It carries an IP65 rating, meaning it offers solid protection against dust and low-pressure water jets, though it does not feature a rugged build designed for more demanding physical conditions.

The Honor 400 5G features a 6.55″ OLED/AMOLED touchscreen with a resolution of 1264 x 2736 px and a pixel density of 460 ppi, delivering a sharp and detailed image. The panel runs at a 120Hz refresh rate and reaches a typical brightness of 5000 nits, making it well-suited for outdoor visibility. Always-On Display is supported, allowing glanceable information without fully waking the screen. The display does not use branded damage-resistant glass and lacks support for HDR10, HDR10+, or Dolby Vision. There is no secondary screen on this device.

The Honor 400 5G is powered by the Qualcomm Snapdragon 7 Gen 3, a 4 nm chipset with a CPU configuration of 1 x 2.63 GHz, 3 x 2.4 GHz, and 4 x 1.8 GHz cores, supported by multithreading and big.LITTLE technology for efficient workload distribution. The SoC integrates an Adreno 720 GPU clocked at 950 MHz, with DirectX 12 and OpenGL ES 3.2 support, and posts a 3DMark Wild Life Extreme score of 1487. The device comes with 12GB of DDR5 RAM running at 3200 MHz and 512GB of internal storage, with a maximum supported memory amount of 16GB and a peak memory bandwidth of 25.6 GB/s. Overall system performance is reflected in an AnTuTu score of 845,000, a Geekbench 6 single-core result of 1122, and a multi-core result of 3256. The chipset also includes integrated LTE, integrated graphics, TrustZone security, and 64-bit support, operating within a thermal envelope of 6W TDP.

The Honor 400 5G uses a dual-lens rear camera system led by a 200 MP primary sensor with an f/2.2 aperture, paired with a 12 MP secondary lens at f/1.9, both built on a CMOS sensor without back-side illumination. Optical image stabilization is built in, and autofocus options include phase-detection and touch autofocus for photos, as well as continuous autofocus during video recording, though laser autofocus is absent. Manual controls cover exposure, ISO, focus, and white balance, while manual shutter speed is not available. The camera supports HDR, burst mode, slow-motion video, timelapse, and in-camera panoramas, but does not offer 360-degree panorama shooting, HDR10 or Dolby Vision recording, or 3D photo and video capture. A single LED flash is present on the rear — without dual-tone or RGB configurations — while the 50 MP front camera sits in a standard position above the display with an f/2.0 aperture, a single lens, and no front-facing flash.

The Honor 400 5G runs Android 15 and includes a broad set of privacy controls, covering clipboard warnings, location privacy options, and camera and microphone access management, though Mail Privacy Protection and cross-site tracking blocking are not present. App tracking can be blocked, and on-device machine learning is supported. On the customization side, the OS offers theme customization, dynamic theming, dark mode, an extra dim mode, customizable notifications, and widget support, while focus modes are not available. Productivity features include split-screen multitasking, Picture-in-Picture, full-page screenshots, a media picker, sharing intents, and the ability to play games while they download. The system also supports offline voice recognition, voice commands, Live Text, app offloading, a child lock, multi-user accounts, and device position tracking. Wi-Fi password sharing and Quick Start are not supported, and OS updates do not come directly from the vendor.

The Honor 400 5G is equipped with a 5300 mAh rechargeable battery that is not removable. It supports 66W wired fast charging, and a charger is included in the box. Wireless charging is not available. A battery level indicator is present, giving users a clear read on remaining charge at a glance.

The Honor 400 5G features stereo speakers but omits a 3.5 mm headphone jack, so wired audio requires an adapter or USB-C headphones. For wireless audio, the device supports aptX HD, enabling higher-quality Bluetooth audio transmission, while standard aptX, aptX Adaptive, aptX Lossless, and LDAC are not available. There is no built-in radio on this device.

The Honor 400 5G supports 5G connectivity alongside a dual SIM configuration, and its wireless capabilities span Wi-Fi 4, Wi-Fi 5, and Wi-Fi 6, with maximum download and upload speeds of 5000 Mbits/s and 160 Mbits/s respectively. Bluetooth 5.4 and NFC are both present, while DLNA certification and ANT+ support are absent. The USB-C port runs on USB version 2, and there is no external memory slot or HDMI output. For navigation, the device includes GPS, Galileo, a compass, a gyroscope, and an accelerometer, but lacks a barometer, heart rate monitor, and motion or optical tracking. Security is handled by a fingerprint scanner; 3D facial recognition and an iris scanner are not included. An infrared sensor is built in, though emergency SOS via satellite, crash detection, and a built-in projector are not available, and no stylus is included in the box.

The Honor 400 5G includes a video light for illumination during video recording. The display is flat rather than curved, uses neither sapphire glass nor an e-paper panel.
