On the fundamentals, both devices are well-matched: dual SIM, 5G, NFC, USB-C, GPS with Galileo support, fingerprint scanner, and accelerometer are all present on each. For most users, this shared baseline covers the everyday connectivity essentials without compromise. However, the Honor 400 5G pulls ahead in wireless networking by supporting Wi-Fi 6 (802.11ax), whereas the Lite tops out at Wi-Fi 5 (802.11ac). Wi-Fi 6 delivers better throughput, lower latency, and more efficient performance in congested environments — a tangible benefit in busy households or offices with many connected devices. This is reinforced by the 400 5G's maximum download speed of 5,000 Mbit/s versus 2,770 Mbit/s on the Lite, reflecting its broader 5G and Wi-Fi capabilities.
The sensor and feature gap adds further separation. The 400 5G includes a gyroscope and an infrared sensor, both absent on the Lite. The gyroscope enables more accurate motion-based gaming, AR applications, and image stabilization assists, while the infrared sensor lets the phone function as a universal remote for TVs and home appliances — a niche but genuinely useful convenience. The Lite's omission of both keeps its feature set leaner. Bluetooth is close but not identical: version 5.4 on the 400 5G versus 5.3 on the Lite, a minor difference that offers marginally improved connection efficiency on the 400 5G.
The Honor 400 5G is the clear winner in connectivity and features. Its Wi-Fi 6 support, higher cellular speeds, gyroscope, and infrared blaster collectively represent a more capable and versatile package — while the Lite covers the essentials competently but lacks the extras that broaden day-to-day utility.
