Updated 2026-05-09
Quick answer
Body Battery estimates your available energy from Garmin heart rate variability, stress, activity, and sleep signals.
What changes the score
Good sleep and relaxed downtime recharge Body Battery. Hard workouts, poor sleep, and sustained stress drain it faster.
How to use it
Watch the trend rather than one number, and compare it with how you feel before changing a training plan.
