Verdict

The Xiaomi Mi Band 3i is a budget-focused fitness tracker featuring a 0.78-inch monochrome AMOLED touchscreen with a 128 x 80 pixel resolution and a capacitive navigation button. Key characteristics include 5ATM water resistance (up to 50 meters), Bluetooth 4.2 connectivity, and a 110mAh battery providing up to 20 days of life. Its main pros are its extreme affordability, long-lasting battery, and lightweight, swim-proof design suitable for tracking steps, calories, and sleep. However, its primary cons are the complete lack of a heart rate sensor and poor screen visibility under direct sunlight.
