Wireless connectivity is where the Redmi Note 14 Pro 5G pulls ahead most meaningfully. It supports Wi-Fi 6 (802.11ax), while the Vivo Y39 5G tops out at Wi-Fi 5 (802.11ac). Wi-Fi 6 delivers higher throughput, lower latency, and better performance in congested environments — particularly relevant in homes or offices with many connected devices. The cellular speed gap reinforces this: the Redmi achieves up to 3270 Mbps on both upload and download, versus the Vivo's 2500 Mbps down / 900 Mbps up. That upload disparity is especially notable for anyone who regularly sends large files, streams live video, or uses cloud backup heavily.
Bluetooth tells a similar story. The Redmi Note 14 Pro runs Bluetooth 5.4 against the Vivo Y39 5G's 5.1 — a newer version that brings improvements to connection reliability and energy efficiency, particularly beneficial for users with multiple paired peripherals. The Redmi also adds an infrared sensor, enabling it to function as a universal remote for TVs and home appliances — a practical convenience the Vivo Y39 5G does not offer.
On the shared side, both phones support 5G, dual SIM, NFC, USB Type-C (USB 2.0), fingerprint scanning, GPS with Galileo, and a matching sensor suite including gyroscope, accelerometer, and compass. Neither supports external memory expansion. Taking stock of the full picture, the Redmi Note 14 Pro 5G holds a clear connectivity edge — faster Wi-Fi, superior upload speeds, a newer Bluetooth version, and an infrared sensor collectively represent a more capable and future-ready feature set.
