- Measures the pulse with a large error, sometimes jumps 20 units up or down. The question arises as to how much one can trust such a device when it begins to talk about the level of oxygen in the blood, the level of stress, or the duration of the sleep phases, if it does not even measure the pulse properly. Yes, the wrist is the worst place to measure. But they called themselves a bracelet - climb into the box.
- Continuous heart rate measurement. If you think that this will let you know your heart rate when you look at the screen, then it is not. There will be some left value of some unknown date, which will immediately begin to jump back and forth. Then you will see the schedule for the day in the application, but if you included a workout, then you will have this schedule anyway, and much more accurate.
- Measurement of stress levels. Twice in a row with an interval of an hour I was late for the train for a couple of minutes. I had to wait two hours in the dark, hungry and cold. For the sake of interest, then I looked at the level of stress at this time - low! The obvious conclusion is a function.
- Sitting at the computer bracelet sometimes counts as daytime sleep.
- Automatic workout detection is another useless feature. Works when it is no longer needed. To be sure, the workout must be started and stopped manually.
- Disconnected from the phone, the bracelet somehow magically begins to determine the distance that I have covered during the workout. Compared with the GPS track - the difference is about 20%.
- Screen sensitivity leaves much to be desired. Swiping and tapas can be performed from the second or third time.
- Disgusting Huawei Health app, inconvenient, crooked, incomprehensible and constantly changing. Requires all possible permissions, requires the creation of a Huawei account, requires all your data. Unpleasant.
- Final chord. At some point, the Health app stopped finding the bracelet. I tried to untie it and reattach it, reinstall the application, reset the bracelet, but nothing happened. Checked on another phone - it works. I have no.
