Set up heart rate detection on the Mi Band 4

Many of the problems can be caused by a bad configuration . By default, the Xiaomi Mi Band 4 sports bracelet is not configured to use the heart rate sensor and we will have to configure it in the Mi Fit application. Once we have entered the app we go to the last tab to click on our bracelet and then go down to the option called ” Heart rate detection “.

Within this section we find several options from which we can choose:

  • Automatic heart rate detection : This option allows us to modify the detection frequency, although it will also affect the battery life.
  • Sleep assistant : With this mode, only when it detects that we are sleeping will it measure our pulsations to better understand our sleep.
  • Both options : With both options we will have all the information, both day and night while we sleep.

In addition, whenever we want we can use the touch screen of the Mi Band 4 to go to the heart rate option and check it manually, at which point we usually encounter all the problems.

Error trying to measure heart rate

When the Mi Band 4 is trying to measure the pulsations and we find an error on the screen, it may be due to a bad position of the bracelet . We remember that we must have it placed above the wrist bone and adjusted to our arm. In case you are not touching the skin, you will not be able to make the measurement or on the contrary it will be very inaccurate.

Clean the heart rate sensor

We usually carry the Mi Band 4 with us all day and therefore it will undeniably pick up dirt which can make the sensor unable to function at full capacity. To clean the Mi Band 4 and specifically the heart rate sensor we must remove the bracelet and use fresh water , for example from the tap. In addition we can add hand soap and gently rub over the entire surface of the capsule.

Is the sensor still failing?

If the problem continues after having followed all these steps, what we should do is reset the data of the Mi Band 4 . Next we go to the app store and check that we have the latest update , then we link our sports bracelet again as we did the first day so that the heart rate sensor works correctly again.
