Honor 400 5G (256GB / 8GB RAM)

The Honor 400 5G has a conventional, non-folding form factor with a height of 156.5 mm, a width of 74.6 mm, and a slim thickness of 7.3 mm, while its total volume comes in at around 85.23 cm³. At 184 g, the device sits at a moderate weight for its size class. It holds an IP65 rating, meaning it offers protection against dust ingress and low-pressure water jets, though it does not feature a rugged build.

The Honor 400 5G uses an OLED/AMOLED touchscreen measuring 6.55″ 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, while also supporting an Always-On Display mode. The screen does not carry 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 that supports 64-bit processing, multithreading, and big.LITTLE technology, operating within a 6W TDP envelope. Graphics are handled by the integrated Adreno 720 GPU clocked at 950 MHz, with support for DirectX 12 and OpenGL ES 3.2, scoring 1487 on the 3DMark Wild Life Extreme benchmark. The device ships with 8GB of DDR5 RAM running at 3200 MHz — expandable up to a maximum of 16GB — alongside 256GB of internal storage, and achieves an AnTuTu score of 845,000, a Geekbench 6 single-core result of 1122, and a multi-core result of 3256. Maximum memory bandwidth reaches 25.6 GB/s, and the SoC also integrates LTE, TrustZone security, and an integrated graphics unit.

The Honor 400 5G features a dual-lens rear camera system led by a 200 MP primary sensor paired with a 12 MP secondary lens, with apertures of f/2.2 and f/1.9 respectively, built on a CMOS sensor without back-side illumination. The rear setup includes optical image stabilization, phase-detection autofocus, touch autofocus, continuous autofocus during video, and a single LED flash, though laser autofocus and a dual-tone or RGB flash are absent. Manual controls cover ISO, exposure, focus, and white balance, while optical zoom is not available; shooting modes include HDR, burst, panorama, slow-motion video, and timelapse, though 360° panorama, manual shutter speed, HDR10 recording, Dolby Vision recording, and 3D capture are not supported. On the front, a 50 MP single-lens camera with an f/2.0 aperture sits in a standard position — not under the display — and does not have its own LED flash.

The Honor 400 5G runs Android 15, an open-source platform that supports multi-user operation, on-device machine learning, offline voice recognition, voice commands, and device tracking. On the privacy side, it offers clipboard warnings, location privacy options, camera and microphone access controls, and the ability to block app tracking, though Mail Privacy Protection and cross-site tracking blocking are not included. The interface supports theme customization, dynamic theming, dark mode, extra dim mode, customizable notifications, notification permission controls, widgets, a media picker, sharing intents, Live Text, full-page screenshots, split-screen multitasking, Picture-in-Picture, app offloading, and a child lock. Users can also play games while they download, and a battery health check tool is present; however, focus modes, Wi-Fi password sharing, Quick Start, and the ability to function as a PC are not available. Direct OS updates from the vendor are not provided on this device.

The Honor 400 5G is equipped with a 5300 mAh rechargeable, non-removable battery that supports 66W fast wired charging, and a charger is included in the box. A battery level indicator is present for convenient monitoring, though wireless charging is not supported.

The Honor 400 5G includes stereo speakers and supports aptX HD for higher-quality Bluetooth audio, but does not offer aptX, aptX Adaptive, aptX Lossless, or LDAC. There is no 3.5 mm headphone jack, and the device does not have a built-in radio.

The Honor 400 5G supports 5G connectivity alongside a dual SIM slot, Wi-Fi 4, 5, and 6, and Bluetooth 5.4, while download speeds reach up to 5000 Mbits/s and upload speeds up to 160 Mbits/s. The device connects via USB Type-C with USB 2.0, includes NFC, and features a fingerprint scanner for biometric authentication, though 3D facial recognition and an iris scanner are absent. For navigation and sensing, it carries GPS with Galileo support, a gyroscope, compass, accelerometer, and an infrared sensor, but lacks a barometer, heart rate monitor, motion tracking, and optical tracking. There is no external memory slot, no HDMI output, no ANT+ support, no DLNA certification, no satellite emergency SOS, no crash detection, and no built-in projector, and a stylus is not included.

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