The Xiaomi Mi Smart Band 4 impressed us by offering almost two weeks of battery life, with use combining notifications, sleep monitoring and daily physical activity. The Mi Smart Band 5 loses 10 mAh (125 mAh) but this is not felt at all during use. With its Amoled screen, and in the absence of GPS, the bracelet can claim to offer excellent battery life. Proof of this is the 65% autonomy available after 6 days of use.
Sports sessions, with increased use of the heart rate monitor, do not do much harm to this autonomy. After 10 days, and having made several sporting outings, the bracelet still offers 50% autonomy. It is quite impressive and we can easily say that even by using it intensively his endurance will be at least 15 days. Note, however, that on this type of product, the battery always tends to run out more quickly over the last tens of percent.
For recharging, it will take a little less than 2 hours.
