Honor 400 5G (256GB / 12GB RAM)

The Honor 400 5G has a non-folding, standard-form design measuring 156.5 mm tall, 74.6 mm wide, and just 7.3 mm thick, with a total volume of roughly 85.23 cm³ and a weight of 184 g. It carries an IP65 rating, meaning it is classified as water resistant against low-pressure water jets, though it does not feature a rugged build intended for heavy-duty or extreme conditions.

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 supports a 120Hz refresh rate and reaches a typical brightness of 5000 nits, while the Always-On Display feature keeps basic information visible without fully waking the screen. The display does not support HDR10, HDR10+, or Dolby Vision, has no branded damage-resistant glass, and there is no secondary screen present.

The Honor 400 5G is driven 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 big.LITTLE technology and multithreading, with a TDP of 6W. Graphics are handled by the integrated Adreno 720 GPU running at 950 MHz, with DirectX 12 and OpenGL ES 3.2 support, scoring 1487 on the 3DMark Wild Life Extreme benchmark. The device ships with 12GB of DDR5 RAM at 3200 MHz — expandable up to a maximum of 16GB — and 256GB of internal storage, while maximum memory bandwidth reaches 25.6 GB/s. It records an AnTuTu score of 845,000, a Geekbench 6 multi-core result of 3256, and a single-core score of 1122, with 64-bit support, integrated LTE, and TrustZone security rounding out the platform.

The Honor 400 5G features a dual-lens rear camera system combining a 200 MP and a 12 MP sensor with apertures of f/2.2 and f/1.9 respectively, backed by a CMOS sensor, optical image stabilization, phase-detection autofocus, and touch autofocus, though it lacks a BSI sensor and laser autofocus. The rear setup includes a single LED flash — not dual-tone or RGB — and offers no optical zoom. Manual controls cover exposure, ISO, focus, and white balance, while manual shutter speed is not available. Video capabilities include slow-motion recording, continuous autofocus during filming, and timelapse, though HDR10 and Dolby Vision recording are not supported. The front camera is a single-lens 50 MP shooter with an f/2.0 aperture, positioned in a standard cutout rather than under the display, with no front-facing flash. Both cameras support HDR mode, burst shooting, and in-camera panoramas, while 360-degree panorama and 3D photo or video recording are absent.

The Honor 400 5G runs Android 15 and includes a broad set of privacy controls, covering location access, camera and microphone permissions, clipboard warnings, and app tracking blocking, though cross-site tracking blocking and Mail Privacy Protection are not present. Customization options include dark mode, dynamic theming, theme customization, widgets, and customizable notifications, while focus modes and Quick Start are not available. Productivity is supported through split-screen multitasking, Picture-in-Picture, full-page screenshots, a media picker, Live Text, sharing intents, and the ability to play games while they download. The system also supports on-device machine learning, offline voice recognition, voice commands, multi-user accounts, app offloading, phone tracking, child lock, and battery health checks, though Wi-Fi password sharing and PC mode are absent. OS updates do not arrive directly from the vendor.

The Honor 400 5G houses a 5300 mAh rechargeable battery that is not removable, and comes with a charger included in the box. It supports 66W wired fast charging, though 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 includes stereo speakers but omits a 3.5 mm headphone jack and 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 5G supports 5G connectivity alongside a dual SIM configuration, Wi-Fi 4, 5, and 6, and Bluetooth 5.4, with download speeds reaching 5000 MBits/s and upload speeds of 160 MBits/s. It connects via USB Type-C, though the USB version is 2.0, and there is no external memory slot, HDMI output, or DLNA certification. NFC is present, and biometric security is handled by a fingerprint scanner; 3D facial recognition and an iris scanner are not included, nor is a stylus. The sensor array covers GPS with Galileo support, a gyroscope, accelerometer, compass, and infrared sensor, while a barometer, heart rate monitor, ANT+, motion tracking, and optical tracking are all absent. Emergency SOS via satellite and crash detection are not supported, and there is no built-in projector.

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