confusingly similar

The Mi strip 1S is 37 x 13.6 x 9.9 mm something slightly larger than the Mi belt (36 x 14 x 9 mm) and 5.5 grams of somewhat heavier (Mi Volume: 5 grams). but the difference is hardly noticeable. Unobtrusive and discreet is the design. According to the motto "Wear and Forget" is to serve the user without bothering him the gadget. Wrist band Mi 1S attracts little attention, but still looks chic and elegant. A display is missing, but that's probably intent and users feel so not constantly forced to read data from the tape Mi 1S.

Cuddly, but sturdy

Some users had complained to the predecessor too soft bracelet that slopes gently from wrist. This error has been corrected with the new model Mi 1S band. The bracelet is now made of very soft, but more robust TPSiV material that is suitable for allergy sufferers. The material feels very supple and is almost unnoticed on the wrist.

colored prospects

Where the sensor housing houses the technology, the bracelet serves only as a support for the band Mi 1S and encloses the actual gadget. If desired, can the bracelet, in our case in black, replace afterwards by a colored alternative. You can when buying but also equal to another color variant (also camouflage variants already exist) Select, but the selection is limited to the bracelet, the sensor housing remains the same. Here you have to just rauspulen the sensor from the bracelet, heavy is the dismantling not.

In addition, the Mi band can be 1S used as an alarm clock or signal generator for incoming calls and app notifications. With a vibrating alert, the band Mi 1S makes you pay attention to the news. Unfortunately, the alarm function is limited to only three alarms. However, there is also an alternative: With the "Early stayer alarm"-Feature evokes the fitness tracker you from sleep when the body is gentle already on waking.

Only in conjunction with the app, the sensor is driven by about a measure during the sleep phases. You can with the Mi-Fit app but also actively your pulse measured by three-point icon > Heart rate.

Benefits for Xiaomi smartphones

In addition, the device provides a clear advantage for owners of Xiaomi smartphones. For users to which the band Mi 1S as a tool to unlock the smartphone display. We know the smart lock feature already from other devices, such as the Nexus series. The unlock feature was the band Mi 1s and the Samsung Galaxy S6 not available as a tester.


First practical experience

In practice, the band Mi 1S was a very unobtrusive companion. I'm not really Armbanduhren- or jewelry holders, but the Fitness Tracker bothered me on the wrist only slightly. So I have taken the tape 1S for four days continuously and the fitness gadget has so well with me while sleeping and of course with my daily activities. And I was amazed at what I was given as a result.

At every turn

So I let the fitness gadget count my daily steps and it also archives the number of calories burned. My most successful day I had on 17 December 2015 where I have a total of 5.37 kilometers covered with 7,793 steps. Here were reportedly burned 273 calories. In between, I also inserted a small sprint, according app I covered 766 meters in seven minutes and it burned 36 calories. Whether this is true, I can not confirm this, but the number of steps and the distance should suit.

Slept well

Yes, I have - for example, on December 17 - and that confirmed to me the app. For me it was amazing to see how well the sleep test works. Whether the stages of sleep really agree as the Mi-Fit app said I could not measure it. But at least the length of my sleep time seems to be right. For this, the band Mi 1S uses the heart rate monitor. And once your sets you sleep, of course, also changes your pulse. Also during the sleep phases of the heart rate monitor measures your heart rhythm. So it can specifically analyze the phases of sleep.

battery pack

30 days endurance

The battery provides only 45 mAh and is to hold up to 30 days according to the manufacturer. Compared to its predecessor the same maturity is at a slightly larger battery (Mi Band: 41 mAh) specified. Since not using a display and Bluetooth 4.0 is used for interfacing with the smart phone, the sensor should be efficient enough to keep the promise. In practice, therefore, for a four-day practice test the battery 85 percent had dropped to 64 percent. And I had not even charged in between the device. However, it must be mentioned that I had all the features enabled except incoming calls and app notifications. Should these functions be turned on, the Mi band would vibrate more often 1S, which should result in an even shorter battery life.

Economical sensor?

While it is not known how much electricity sucks the optical heart rate monitor, but it can be assumed that these claims the battery next to the vibration motor most ,. This should negatively affect the battery life also, if you will constantly measure your sleep habits. Although the scenario was in practice before, but with empty battery flashing as a visual signal transmitter every three LED lights on. Then it's time again to fuel flow.

final verdict

Wear and Forget

The Mi 1S band is a discreet and very aesthetic fitness gadget that can score with a minimalist design and also its unobtrusiveness. Compared to its predecessor was only slightly filed on the exterior, but also the technology inside shows no great changes. Another new feature is the heart rate monitor that comes with sleep and when training is used. This is well hidden in the housing core installed and is not prominently visible. And these are also the advantages of the Mi 1S band. be athletic, does not mean that the right gadget is expected to flash on the wrist conspicuously prominent and it is Xiaomi keeps the band Mi 1S.

Display los happy

Because the display at Mi 1S band is missing, a smartphone for data analysis is needed. With the companion app was produced quickly and easily connect via Bluetooth. In terms of functionality you offers fitness gadget to all the basic functions that we know from competing models at a slightly higher price segment, such as the Jawbone UP3. So the gadget accurately displays your steps, calories burned, distance covered and even heart rate.

Buy or leave?

All in all, the Xiaomi Mi 1S band is a great gadget that is worth to buy. Whether experienced athletes or beginners, the gadget shows you the data needed without constantly bugging. And I like it very much! With a current price of 27 euros, it is currently the cheapest Fitness Tracker with heart rate monitor on the market. The gadget is designed especially for beginners, because the app has little depth, which could deter some experienced athletes. But the options offered ranging from completely, for people who do not go to sports every day, but still want to see what progress you wins. For this group of people, including yours truly, the Xiaomi Mi 1S band should be given as a gift idea for Christmas into consideration.
