In the latest wearables arrived on the market with the Xiaomi and Amazfit brand, we find the presence of the PAI value, but perhaps some of you still don't know what it is. This value is in addition to the other collected by the wearable smart, taking for example the recent Xiaomi Mi Band 5, the monitored data is more accurate by 50% compared to previous generations, showing heart rate, sleep monitoring and pedometer to name a few.
The PAI value was introduced by Huami on their Amazfit devices and basically we could define it a personal indicator of physiological activity. In other words, it's a value that tells you how healthy you are in terms of physical activity or if you need to improve.
Everything you need to know about the PAI index of your fitness trackers
PAI is the English acronym for Personal Activity Intelligence and consists of an algorithm that, based on various data, returns a result that represents your physical condition. In particular, the data used by this function are the heart rate and other personal data such as weight or gender, therefore PAI is a personal index that differs with the same data collected by a person who weighs 100 kg from one that weighs half.

But be careful, because the PAI index only works if the wristband heart rate monitoring is turned on on your device. To turn heart rate monitoring on or off, you need to do the following:
- Open the Mi Fit / ZEPP app on the smartphone you have associated with your wearable;
- Go to the Profile section of the app and select your wearable;
- At this point, scrolling through the options, you will see the item for enabling automatic heart rate detection, which to better calculate the PAI index must be set to a frequency of at least 5 minutes.
Well, now that you know what PAI is and how it works, you are ready to keep in training. We then recall that the PAI value is not exclusive to Mi band 5 but now present on all Huami devices and therefore Amazfit series, with the exception of the most obsolete wearables, such as the first generation Bip d. And which smartwatch do you rely on for the collection and monitoring of your fitness data?
