Body battery problem

Hi, I have a Garmin 945 for few months. How can it be that the body battery is on 5% since yesterday evening, and the charged and drained are on zero 20 hours? All the information like heart rate, sleeping stages, stress, steps sync with no problems. Usually at night the body battery charge to 75-100%.

  • What does your stress look like during your sleep? If you got stress body battery will not recharge. It should be all blue during night and then the body battery will recharge. Common causes to stress during sleep is alcohol, coffee and other substances late in the day. Illness like Covid-19 will probably not help either.

    Start by trying with a restart of the watch. That usually helps if you can rule out any other causes to the stress measurements.
