Even after good sleep at night the body battery sticks at 5-10 points. what to do to reset or activate my Lily
You can reset the watch following the steps described in the manual: Lily Owner's Manual - Restoring All Default Settings, but it then can take up to a week, before the watch established baselines, and start showing realistic numbers. See more info at Body Battery Frequently Asked Questions | Garmin Customer Support
I would first try simply powering it off and then on again, and see whether it helps. Also try adjusting the fit and position of the watch, for the case it does not register your heart rate (and especially the HR Variability) correctly.
