Apple Watch body battery is a concept that helps you track your daily energy levels and recovery so you can plan your activities better. While Apple has not introduced an official body battery feature yet, Apple Watch owners can get the same benefit through third-party apps available on the App Store.
The idea originally became popular with Garmin devices, which calculate body battery by analyzing heart rate variability, stress, activity, and sleep.
So, let’s find out all about the Apple Watch body battery feature and how to set it up!
