Cellular connectivity is where the two phones part ways most fundamentally. The Infinix Note 50 Pro 4G is locked to 4G LTE, with a maximum download speed of 650 Mbits/s. The Xiaomi Redmi Note 14 Pro 5G adds 5G support and — more strikingly — achieves up to 3270 Mbits/s in both download and upload speeds, a gap that reflects not just 5G capability but a substantially more capable cellular modem. For users in 5G-covered areas, this translates to faster downloads, lower latency, and a more future-proof device as 4G networks gradually get deprioritized by carriers over time. The Xiaomi also supports Wi-Fi 6 alongside Wi-Fi 5 and 4, while the Infinix tops out at Wi-Fi 5 — Wi-Fi 6 delivers better throughput and reduced congestion on busy networks.
Both phones share Bluetooth 5.4, USB Type-C with USB 2.0, dual SIM, NFC, and an identical sensor suite including GPS, gyroscope, accelerometer, and compass. The differentiators at the feature level cut in opposite directions: the Xiaomi adds an infrared sensor, enabling it to function as a universal remote for TVs and appliances — a handy everyday utility. The Infinix counters with a built-in heart rate monitor, which the Xiaomi lacks, offering a basic biometric capability without needing a wearable.
Taken together, the Xiaomi Redmi Note 14 Pro 5G holds a decisive connectivity edge. Its 5G support, dramatically higher data speeds, and Wi-Fi 6 compatibility represent a generational leap in network capability over the Infinix. The infrared sensor is a practical bonus on top. The Infinix's heart rate monitor is a noteworthy exclusive, but it cannot offset how significantly the Xiaomi outpaces it in core connectivity infrastructure.
