Much of this category is shared ground — both phones offer 5G, Wi-Fi 7, dual SIM, NFC, USB-C, infrared, and an identical sensor suite including GPS, gyroscope, compass, and accelerometer. The shared Wi-Fi 7 support is worth highlighting as a forward-looking feature, enabling faster throughput and lower latency on compatible routers regardless of which device you choose.
The meaningful divergences cut in opposite directions. The iQOO Z10 Turbo Pro ships with the newer Bluetooth 6, versus the K90 Pro Max's Bluetooth 5.4 — a genuine advantage for wireless peripheral pairing, offering improved range, connection stability, and power efficiency. However, the K90 Pro Max counters decisively with USB 3.2, while the iQOO is limited to USB 2.0. This is a substantial real-world gap: USB 3.2 enables wired file transfers many times faster than USB 2.0, and also unlocks capabilities like display output and faster tethering that USB 2.0 cannot support. Cellular throughput also favors the K90 Pro Max, with a peak download speed of 10,000 Mbits/s compared to the iQOO's 4,200 Mbits/s — relevant for users in markets with advanced 5G mmWave infrastructure.
The two phones trade blows here, but the K90 Pro Max's USB 3.2 and dramatically higher cellular download ceiling represent more impactful day-to-day advantages than the iQOO's Bluetooth 6 lead. On balance, the Xiaomi Redmi K90 Pro Max holds the connectivity edge, particularly for users who regularly transfer large files or demand maximum 5G throughput.
