The HONOR 400 Smart is designed for users who prioritise long battery life and everyday reliability over premium materials or advanced flagship features. It combines a large display, a high-capacity battery, and practical performance in a straightforward design that’s built for regular daily use.
This positioning makes it well suited to people who spend a lot of time on their phone for messaging, browsing, navigation, and media, and want a device that can comfortably last through long days without frequent charging.
The HONOR 400 Smart features a 6.77-inch LCD display with a Full HD+ resolution and a 120Hz refresh rate. The large screen size makes it comfortable for reading, scrolling, and watching video, while the higher refresh rate helps everyday interactions feel smoother than on standard 60Hz panels.
Although it uses an LCD panel rather than AMOLED, the display offers good brightness and clarity for everyday use, particularly indoors and in typical outdoor conditions.
On the rear, the HONOR 400 Smart uses a dual-camera setup led by a 50MP main sensor, supported by a 2MP depth sensor for portrait-style shots. This setup is designed to cover common photography needs such as everyday photos, quick snapshots, and casual portraits.
While it isn’t positioned as a camera-focused flagship device, the camera system is well suited to regular use and social sharing, delivering consistent results without complex shooting modes. A front-facing camera handles selfies and video calls.
Battery life is one of the strongest features of the HONOR 400 Smart. It includes a large 6,500mAh battery, which is designed to comfortably support heavy daily use without needing to recharge partway through the day.
This makes it particularly appealing for users who rely on their phone for navigation, streaming, and communication over long periods. Fast charging support helps reduce downtime when the battery does eventually need topping up.
The phone has a solid, practical build that prioritises durability over slimness. It also includes protection features aimed at handling everyday knocks and splashes, making it better suited to regular use without constant care.
Performance is powered by the Snapdragon 6s Gen 3 chipset, which is designed for smooth everyday operation rather than demanding gaming workloads. It handles common apps, multitasking, and media playback reliably, while maintaining efficiency to support the phone’s long battery life.
