About the Honor 400 Smart
The Honor 400 Smart 5G hits a sweet spot that budget phones rarely manage: 5G connectivity, a large 6,500mAh battery, and a 120Hz display, all starting from around 150 pounds. The Snapdragon 6s Gen 3 chip keeps things running smoothly for daily tasks, and the 6.77-inch screen is pleasant to use despite its HD+ resolution. Battery life is the standout feature here, with the massive cell easily lasting two full days under moderate use and potentially stretching further for lighter users. The 50MP main camera is capable in good light, though it lacks the computational photography tricks of pricier phones. Software support through to 2030 is a genuine differentiator at this price, meaning the phone should remain secure and functional for years. IP65 water resistance and SGS-certified drop resistance add practical durability. The compromises are predictable: the HD+ screen lacks the sharpness of full-HD panels, 35W charging is adequate but not fast by modern standards, and the processor will not handle demanding games well. For anyone who values battery longevity and 5G access over raw performance, the 400 Smart delivers where it counts.
