Across the core connectivity checklist, these two phones are remarkably well-matched — both support dual SIM, NFC, USB Type-C, the same Wi-Fi 4/5 standards, expandable storage, and a fingerprint scanner. Where they begin to diverge is in cellular throughput: the Redmi Note 14 4G supports download speeds up to 650 Mbps, more than double the Realme C71's 300 Mbps ceiling. In everyday use on typical 4G networks this gap rarely surfaces, but in areas with strong LTE infrastructure or carrier aggregation, the Redmi can extract significantly faster real-world data speeds. Upload speeds are identical at 150 Mbps for both.
Sensor selection tells a more consistent story in the Redmi's favor. It includes a gyroscope — which the C71 lacks — a sensor that enables accurate screen rotation response, augmented reality applications, and more precise motion-based gaming controls. The Redmi also adds an infrared sensor, allowing it to function as a universal remote for TVs and appliances, a convenience feature with no equivalent on the C71. The Redmi's Bluetooth 5.3 edges past the C71's 5.2, though this difference is minor in practice. Both devices share GPS, compass, accelerometer, and Galileo satellite support, giving them equivalent navigation and basic motion-sensing capability.
The Redmi Note 14 4G edges ahead in this group, not through any single dominant feature but through a consistent accumulation of extras — faster LTE throughput, a gyroscope, and an infrared blaster — that the C71 simply does not offer. For users who want a more versatile and sensor-complete device, the Redmi is the stronger choice here.
