Blood oxygen saturation test

The method of use is very simple. Select the blood oxygen detection function on the dial and keep the wrist flat for 1 minute to complete the blood oxygen measurement.

Because the accuracy of the measurement needs to be taken care of, the blood oxygen detection, like most current products, only supports a single manual blood oxygen detection, and the value of each measurement will be displayed in the form of dots in the watch and mobile APP.

Paying attention to one’s blood oxygen level on a daily basis is very useful for avoiding work under the condition of low blood oxygen saturation and dizziness. In plain areas, the blood oxygen saturation level should not be less than 94%, otherwise the oxygen supply is insufficient, and you need to rest or even inhale oxygen in time.

Heart rate monitoring

Huami Amazfit GTR 2 supports all-day automatic heart rate monitoring. The frequency of heart rate detection can be changed in the settings to obtain icons with different accuracy.

Huami Amazfit GTR 2 supports the PAI health assessment system. It can generate an exclusive health goal for each person based on physiological data such as a person’s age, weight, gender, and so on. By completing this goal every day, you can get the corresponding PAI vitality index.

The PAI vitality index is different from the traditional calculation of scores by step counting and exercise time, but it combines heart rate sensors, acceleration sensors, etc. to comprehensively record all exercise conditions in a day. There are even specific exercises, time, and intensity suggestions in the APP, which can use fragmented time to produce the best exercise effect.

Amazfit GTR 2 Sports Modes

Huami Amazfit GTR 2 uses a GPS+GLONASS dual positioning system, which can operate independently without the assistance of a mobile phone. The combination of dual positioning systems can also ensure that the positioning system can continue to work stably when used outside.

It is also more convenient to open it directly here.

Endurance

In terms of battery life, the author turns on automatic heart rate detection + auxiliary sleep detection, all-day pressure monitoring + sleep respiration quality monitoring, and under the premise of exercise and frequent use of the watch with the screen on, the power consumption is 25% after using it for nearly 46 hours. Under the author’s heavy usage habits, the battery life of Huami Amazfit GTR 2 is about 9 days.

Considering that this is a test machine, there is still a lot of room for optimization in daily power consumption. In the future, when all-day pressure monitoring and sleep-respiratory quality monitoring are turned off, battery life will be closer to the official standard of 14 days.
