Apple 13promax always has steps when sleeping at three in the morning.

It may be because when you sleep at night, you put your mobile phone next to you, and a slight rotation or vibration will be sensed by the sensor, which is very sensitive.

Data expansion:

Mobile phone counting is usually around 12 o'clock in the evening, and then counting after 12 o'clock. But WeChat counting is very sensitive, unlike other software. If you move your phone, it will record a step. If you don't move your mobile phone, it may be that your mobile phone vibrates when you turn over at night or go to the toilet. It's nothing. Don't think too much. Wechat counting is actually very accurate and trustworthy. How many steps you have taken are correct and there are no mistakes at all. Your mobile phone doesn't work. This situation is mainly when sleeping at night, fidgeting and moving around, and the vibration generated by the mobile phone will produce steps. For mobile phone step counting, it can only be used as reference, not as absolute data. You can pick up the phone and shake it, and you will find that the steps of the phone will increase rapidly. Therefore, the principle of mobile phone step counting is to generate steps by shaking or shaking.
