Connectivity is another category where the Honor 400 Lite pulls notably ahead. Most significantly, it supports 5G, while the X5c is limited to 4G — a difference that affects not just peak download speeds but also future-proofing. The 400 Lite's maximum download speed of 2770 Mbits/s dwarfs the X5c's ceiling of 300 Mbits/s, reflecting the fundamental throughput gap between 5G and LTE. For users in areas with 5G coverage, this translates to considerably faster streaming, downloads, and cloud-based tasks on mobile data. The 400 Lite also runs a newer Bluetooth 5.3 versus the X5c's 5.1, offering incremental improvements in connection stability and energy efficiency.
Two further differentiators stand out. The 400 Lite includes NFC, enabling contactless payments and quick device pairing — a feature entirely absent on the X5c. It also has a digital compass, which is required for accurate map orientation and navigation apps to function properly without movement; the X5c lacks one. On the other side, the X5c offers a microSD card slot for expandable storage, compensating somewhat for its smaller base storage, while the 400 Lite has no external memory option.
Shared ground includes dual-SIM support, USB Type-C at USB 2.0 speeds, Wi-Fi 5, GPS with Galileo support, an accelerometer, and a fingerprint scanner on both devices. Weighing everything together, the Honor 400 Lite holds a clear connectivity advantage — 5G support, NFC, a higher Bluetooth version, and a compass represent a broader and more modern feature set. The X5c's expandable storage slot is a useful but narrower counterpoint.
