Summary of the review

HONOR 400 Smart 5G Review - Paperweight

The Honor 400 Smart 5G is identified as a durable mid-range device featuring a 6.77-inch 120Hz display and a 7.3mm design. It is characterized by its significant 6,500 mAh battery, which offers up to four days of usage, and an IP65 rating for water and dust resistance. The phone operates on MagicOS 9, delivering a smooth user experience with AI capabilities. Pros include excellent battery endurance supported by 35W fast charging and a robust, thin construction. However, the device has limitations, such as a 1 hour and 27-minute charge time for a full recharge. Furthermore, performance is sufficient for daily tasks but lacks power for intensive gaming, and the camera, while adequate for social media, produces noticeable noise in low-light conditions. Overall, the Honor 400 Smart 5G is positioned as a reliable, long-lasting daily companion rather than a high-performance device.

Summary of the review

HONOR 400 Smart: the all-rounder you just can't drain

The Honor 400 Smart, as reviewed by Tom's Hardware Italy, is presented as a concrete, entry-level device focusing on extreme durability and battery life over high-end specifications. It features a robust design with 5-star drop protection, IP64 rating, and a large 6.77-inch 120Hz LCD screen suitable for daily use. The device is praised for its "all-rounder" usability and integrated smart features, despite utilizing budget-conscious materials. Performance is driven by the Snapdragon 6s Gen 3 processor, which handles daily tasks efficiently but struggles with demanding games. The key highlight is the massive 6,500 mAh battery that offers industry-leading longevity. However, this is paired with relatively slow 35W charging, taking roughly 90 minutes to fully charge. The 50MP main camera produces solid, clear images in good lighting, though it loses detail and introduces noise in low-light environments. The inclusion of a physical AI button for rapid access to functions like Magic Portal adds significant utility. Ultimately, the device is recommended for users prioritizing long-lasting power and ruggedness over flagship performance.
