The trend line is an illustration, not a personal energy measurement.
Body Battery is Garmin’s estimate of energy reserves. It uses information such as sleep, stress, activity and heart rate variability (small changes in the time between heartbeats). It is a helpful view of a pattern, not a direct measurement of how much energy you have left.
Charged and drained
Garmin uses these labels to describe changes in the estimate. Look at the day and night together rather than judging yourself by a single low point.
What to check
- Was the watch worn and recording normally?
- Does the sleep period look roughly right?
- Was the day different from usual?
- Does the pattern match how you feel?
Use it as a conversation starter
A busy workday, a broken night with family, and a training session can all belong in the same discussion. Tell your coach what happened rather than trying to explain everything with one score.
If it worries you
Do not use a reassuring number to dismiss symptoms or a low number to diagnose a problem. Ask a healthcare professional about persistent changes or symptoms that concern you.
