Love the new Mi 7 band. Battery life is considerably better than my Apple Watch, but still not as long as I had hoped (around 3 to 4 days with various acceptable deactivations to full time display, sleep breathing settings, stress measurement, blood oxygen levels, etc). If I want to run all or most functions, I almost can get 2 days on a full charge - which is not that great. I noticed that if you deactivate the heart rate setting to anything other than capturing data every minute, when you exercise, your results will not include any sort of heart rate information - which can then invalidate your daily tracking for PAI and other factors.Some wishes:- heart rate does not seem to track properly at the start of exercises where your heart rate increases rapidly (ie running or bicycling). But, for others where your heart rate builds slowly, it seems to work fine.- the range on the Bluetooth is not as strong as with my Apple Watch. This results in more pairing due to lost connection.- I wish it had the functionality to respond to text messages and phone calls - but at the price point, this is minor.One big question - when is support in the US coming for the Mi band 7 pro. I purchased one and neither the Zepp Life app, former Zepp app or any of the Mi apps (Mi Fit, etc) seem to recognize the new band ?

I have the fitness band, not a watch or a scale, and for me this product and app are both great. There are a few things about this app that I wish There are some UI adjustments that would make this app better and they certainly could benefit from having a native English speaker review the language. Some more watch faces designed for western culture in addition to (not instead of) the ones they have now would also be a great addition. I personally am a minimalist that likes data so some watch faces designed with that in mind would be good as well. As for the fitness tracker itself, it is a good product. Like the app, it could benefit from some more UI thoughtfulness as well as a native English speaker going through its interface. I’d love a larger screen as well but that would I’m sure raise its cost and its current price is one of its huge of its huge benefits. For what you get from the device and this app for the price is an fantastic deal which is why this gets five stars despite any flaws.

I went on one charge for six days and only ran the battery down to 70%. I haven't had an issue connecting to the app or pairing to my phone. I know many others have though by reading other reviews. I wish the watch faces had the option to change to 12 hour time instead of 24 hour time. Heart rate isn't exactly accurate. The GPS takes a long time to get your location so you can't just start your activity right away if you want the GPS to track your entire workout. The sleep monitor is very convenient. Sometimes the weather says it can't display and to update the app but it isn't often. I have gotten all my notifications from all my apps with no problems. When you turn on the "sleep" mode you still get the notifications on the watch, it just doesn't vibrate. I'd like to be able to turn this mode on and not receive any notifications.

Sorry for the short review. App Store app is awful for leaving a detailed review—keep losing work. Summary of what I was trying to write before...mi band 2 has fantastic functionality for the cost. It’s also highly accurate...way more accurate than leading brands in measuring sleep and steps. I find that heart rate is also accurate. I rant and rave about how awesome this band is. It’s perfect for me. This app in general is also terrific. Makes tracking my health behavior addictive. I love the interface. I initially had to dig into the app to find more detailed information or even historic views to monitor over time, but it’s there. Bugs—these annoying bugs need to be fixed. The band does not stay connected via Bluetooth long enough for me to receive SMS and/or call notifications on my wrist. Only worked the 1st day for a few hours. I can’t toggle the notifications off in the app to try to reset either. Gets stuck in a never-ending little circle that indicates that a change is being transmitted/processed. Either re-starting the app or restarting the phone shows the initial setting. The same updating circle appears when I try to toggle the alarm on, by the way. Bluetooth works fine otherwise...the band syncs with the app via Bluetooth so the tracking features work beautifully.
