Xiaomi launched his first band as a name Mi band at?999 . I purchased this band six months before, now I am not having this band because I lost my band in some place. After using this band for 1 to 2 months I can say that in 1 to 2 months I only charge this band by 2 times. So this band is nearly gives 30 days of backup, which is a very great thing. it is very accurate device.
It can easily connect to your smart phone, if you're using Android smartphone then you need to download mifit application from Play Store after that it will easily connect to your band and it takes a record of daily, how much you burn calories, how much you walk in that day how much you sleep last night was it completely or not . So this is a very good thing about this band.
So if your want to purchase a band having great battery life as well as affordable than must buy it.
