Xiaomi set a record for mi Band 4 sales. Within eight days from the warehouses were shipped 1 million devices. Representatives of the company said that during each hour had to ship about 5 thousand devices. Even with Mi Band 3, everything turned out not so successful – last year the manufacturer crossed this mark after 17 days from the start of sales.
Recall mi Band 4 is equipped with a color AMOLED screen with a diagonal of 0.95 inches. The body is plastic, completely protected from water, equipped with a heart rate sensor and switches depending on the training mode. The 135 mAh battery is enough for 20 days of battery life.
