Xiaomi just announced the latest iteration to its most popular fitness band, the Mi band 7. The Mi band 7 succeeds last year’s Mi band 6 sporting a bigger AMOLED screen and battery and a slightly more powerful CPU. Frankly, the Mi band 7 isn’t a significant upgrade from last year’s model. So if you’re looking for an upgrade, it’s probably not worth it. However, if you’re getting a fitness band for the first time, the Mi band 7 seems to be the most refined model in Xiaomi’s fitness band product catalog.
