The HONOR 400 Smart 5G is built around a straightforward proposition: substantial battery capacity, rapid wired charging, a high-resolution primary camera and a bright, fast-refreshing AMOLED display. That combination gives the phone a broad technical remit, with 5G connectivity and a Snapdragon 7 Gen 3 platform adding a contemporary foundation beneath the specification.
A display with clear ambition
Its 6.55-inch AMOLED panel has a 2736×1264 resolution and a 120Hz refresh rate. Those figures provide the technical basis for detailed presentation and fluid motion, while the quoted 5000-nit peak brightness indicates considerable brightness headroom on paper. The size also gives the phone a substantial visual canvas, though buyers prioritising a compact handset should note the corresponding screen footprint.
The battery specification is one of the more persuasive elements. A 6000mAh cell should provide substantial capacity for everyday use, while 80W charging is designed to replenish it quickly. HONOR states that the phone can reach 40% in 15 minutes, which gives the charging system a useful, concrete advantage for shorter charging sessions. The trade-off is equally clear: wireless charging is not supported, so charging remains a wired-only proposition.
Camera hardware
The rear camera system is led by a 200MP sensor with a 1/1.4-inch sensor size, an f/1.9 aperture and optical image stabilisation. That is a strongly specified primary camera platform, with stabilisation providing a technical basis for reducing camera movement during capture. The supporting 12MP ultrawide camera adds a wider perspective, although its resolution is notably below the main camera's 200MP figure. The front camera is specified at 50MP, giving the phone a high-resolution selfie camera on paper.
Hardware and ownership fit
The Snapdragon 7 Gen 3 uses an octa-core CPU and Adreno 720 GPU, placing the phone on a modern mobile chipset platform. Buyers can choose between 8GB and 12GB of RAM, alongside 256GB or 512GB of storage. That range allows the specification to be tailored towards either a lower or higher-capacity configuration without changing the phone's central identity.
At 184g and 7.3mm thick, the handset has a defined physical profile, while IP66 protection provides a stated level of resistance against dust and water. MagicOS 9.0, based on Android 15, supplies the software foundation, and five colour options broaden its visual choice.
