The single biggest differentiator in this group is cellular connectivity. The Honor 400 Lite supports 5G, while the Honor X7d 4G is limited to 4G LTE — and the downstream speed figures make this gap concrete: the 400 Lite is rated for up to 2770 Mbits/s download versus just 390 Mbits/s on the X7d 4G. In practical terms, this means the 400 Lite is significantly better positioned for fast mobile data in areas with 5G coverage, and is more future-proof as 5G networks continue to expand. For users in 4G-only regions, this advantage narrows considerably, but for anyone in a major urban area or planning to keep their phone for several years, it is a meaningful consideration.
Bluetooth tells a similar story of a smaller but real gap. The 400 Lite uses Bluetooth 5.3 versus Bluetooth 5.0 on the X7d 4G. Newer Bluetooth versions bring incremental improvements in connection stability, energy efficiency, and interference handling — not dramatic differences, but worthwhile in scenarios like simultaneous multi-device pairing or sustained wireless audio connections. Both phones match on Wi-Fi (Wi-Fi 5), USB Type-C with USB 2.0, dual SIM, NFC, GPS with Galileo support, fingerprint scanner, and accelerometer — a solid shared baseline for everyday connectivity and convenience.
Across this group, the Honor 400 Lite holds a clear and decisive advantage. Its 5G support alone — reflected in a download speed ceiling seven times higher than the X7d 4G — makes it the stronger choice for connectivity-conscious users, and its newer Bluetooth version adds a further, if modest, edge. The X7d 4G offers no offsetting connectivity advantage anywhere in this group.
