Honor 400 Pro 5G

The Honor 400 Pro 5G has a conventional, non-folding form factor measuring 156.5 mm tall, 76.1 mm wide, and 8.1 mm thick, with a total volume of approximately 96.47 cm³ and a weight of 205 g. It carries an IP68 ingress protection rating, classifying it as waterproof, though it does not feature a rugged build in the traditional hardened sense.

The Honor 400 Pro 5G uses an OLED/AMOLED touchscreen measuring 6.7″ with a resolution of 1280 x 2800 px and a pixel density of 460 ppi. The panel runs at a 120Hz refresh rate and reaches a typical brightness of 5000 nits, while also supporting an Always-On Display mode. It does not support HDR10, HDR10+, or Dolby Vision, has no branded damage-resistant glass coating, and there is no secondary screen present.

The Honor 400 Pro 5G is powered by the Qualcomm Snapdragon 8 Gen 3 system-on-chip, fabricated on a 4 nm process with an 8-thread CPU configuration running at speeds spanning 2.26 GHz up to 3.3 GHz across its big.LITTLE core arrangement, with a TDP of 12.5W. It supports HMP and multithreading, and graphics are handled by an integrated Adreno 750 GPU clocked at 900 MHz with 3 execution units, supporting DirectX 12, OpenGL 3.2, OpenGL ES 3.2, OpenVG 1.2, and OpenCL 2, driving a single display. The device comes with 12 GB of DDR5 RAM running at 4800 MHz across 2 memory channels, a maximum memory ceiling of 24 GB, a maximum memory bandwidth of 76.6 GB/s, and 512 GB of internal storage, complemented by 1 MB of L2 cache and 12 MB of L3 cache. Benchmark results stand at an AnTuTu score of 2,010,000, a Geekbench 6 single-core score of 2213, and a Geekbench 6 multi-core score of 7325. The SoC also integrates LTE, TrustZone security, and 64-bit support.

The rear camera system on the Honor 400 Pro 5G consists of three lenses — 200 MP, 50 MP, and 12 MP — with respective apertures of f/1.9, f/2.4, and f/2.2, built around a CMOS sensor and paired with optical image stabilization and 3x optical zoom. Autofocus is handled via phase-detection and touch autofocus for photos, as well as continuous autofocus during video recording, though laser autofocus is not present. The single LED flash does not support dual-tone or RGB output, and there is no front-facing flash. Shooting modes include HDR, burst, panorama, timelapse, slow-motion video, manual exposure, manual ISO, manual focus, and manual white balance, while manual shutter speed, HDR10 recording, Dolby Vision recording, 360-degree panorama, and 3D capture are not supported. The front camera uses a dual-lens arrangement with 50 MP and 2 MP sensors, is not positioned under the display, and the system does not use a back-illuminated sensor.

The Honor 400 Pro 5G runs on Android 15 and includes a broad set of software features covering both usability and privacy. 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 present. The interface supports dark mode, dynamic theming, theme customization, widgets, and an extra dim mode, while productivity is aided by split-screen multitasking, picture-in-picture, full-page screenshots, a media picker, sharing intents, customizable notifications, notification permission controls, and Live Text. Additional capabilities include on-device machine learning, offline voice recognition, voice commands, multi-user support, app offloading, battery health check, device position tracking, and the ability to play games while they are still downloading. Focus modes, Wi-Fi password sharing, Quick Start, and the ability to function as a PC are not supported, and the device does not receive direct OS updates from the vendor.

The Honor 400 Pro 5G is equipped with a 6000 mAh rechargeable battery that is not removable, and a battery level indicator is present. Wired fast charging is supported at 100W, and wireless charging is available at up to 50W, with reverse wireless charging also on board for topping up other devices. A charger is included in the box.

The Honor 400 Pro 5G features stereo speakers but does not include a 3.5 mm headphone jack or a built-in radio. For wireless audio, it supports aptX HD, while aptX, aptX Adaptive, aptX Lossless, and LDAC are not available.

The Honor 400 Pro 5G supports 5G connectivity and accommodates two SIM cards, with wireless networking covering Wi-Fi 4 through Wi-Fi 7 (802.11n, 802.11ac, 802.11ax, and 802.11be). Bluetooth 5.4 is on board alongside NFC, and the device connects via a USB Type-C port running USB 2.0; there is no HDMI output, no external memory slot, and no DLNA certification. Download speeds reach up to 10,000 Mbit/s and upload speeds up to 3,500 Mbit/s. Onboard sensors include GPS with Galileo support, a compass, an accelerometer, an infrared sensor, and a fingerprint scanner, while a gyroscope, barometer, heart rate monitor, and motion or optical tracking are absent. The device does not include 3D facial recognition, an iris scanner, ANT+ support, crash detection, emergency SOS via satellite, or a built-in projector, and no stylus is included.

The Honor 400 Pro 5G includes a video light, while its display is flat rather than curved and does not use sapphire glass or e-paper technology.
