Mi band 1s works with Xiaomi’s Mi fit application, which you can download from Google Play or the App store (depending on your operating system). Keep in mind that Mi fit requires a registration, so your data can be synced in the cloud. The application has simplistic design, which we find beautiful. It offers two major sections – for measuring your activity (counting steps, distance and calories) and your sleep (duration, start and end time, deep and light sleep).
You can see the remaining battery charge of your band in the Settings. Most of the options are also located there. Another section is the Alarm, which is pretty self-explanatory. The next section is Profile, where you can see your total activity (for all the time being), set up your daily goal and change the measure units. You even have an option to sync the Mi fit app with the Google fit app (we used the Android version of the Mi fit app).
There’s a standalone section for heart rate measurement. You must activate the heart rate monitor manually. It’s the only way to measure and display your heart rate. Even enabling the automatic heart rate monitor during sleep will just help for collecting more accurate data, but won’t record your heart rate.
The last is the Share section, which (we think) is again self-explanatory.
All your data from the previous weeks (both sleep and activity) is stored in the app, so you can easy check it.
Xiaomi Mi band 1s battery life
Perhaps the most important feature for most of us is the battery life of the wearable. Xiaomi has made some kind of magic with the 45 mAh battery. Mi band achieves superb results, just like its predecessor. The battery drops by less than 3% per day with about 5 data syncs per day. This means that we don’t have our bluetooth turned on all the time. However even we do, Xiaomi claims that the bluetooth connection doesn’t affect the battery performance of Mi band 1s. You can see the screenshots in the previous section. We had our battery charged to 40% and it fell to 19% after 11 days.
Just a few more things to add regarding the conditions, which we had for testing the Xiaomi Mi band 1s. We didn’t use it neither for notifications, nor alarms, however we used the heart rate sensor for improving the sleep monitor accuracy. This means that the band didn’t vibrate on each text message/call/notification we received, but at the same time it measured our heart rate during the night in order to improve the sleep data accuracy.
Mi band 1s is a nice addition to the wearable family. It offers great battery life and features like heart rate sensor for as low as $25. This is a price, which nobody can beat by the present moment. However Xiaomi Mi band 1s has its up and down.
We liked: superb battery life, beautiful design and great build quality, nice looking app (and community, which contributes for alternative apps)
We didn’t like: collected data is not 100% accurate (the activity sensor counted steps in situations like – brushing teeth, grinding vegetables, playing with a dog). At the same time data is not collected, when pushing a shopping cart in the store for example. In rare occasions sleep data doesn’t appear when synced in the morning (but it appears when synced later during the day)
