How long will it take to charge my Garmin wearable device?

Charging a fully depleted battery takes about 60 to 90 minutes. For more tips and advice about charging your Garmin wearable please visit https://support.garmin.com/.

 

How often do I need to charge my Garmin wearable device?

The battery life of your device will depend on a number of factors including the setup of your research project and how often you interact with your device.  It can be anything from a couple of days up to a week.  For most projects, we recommend charging your device at least every other day.

How accurate is my Garmin device for measuring heart rate, Sp02 or other physiological data? 

Garmin devices have been used successfully for physiological data collection across many different types of research projects, including clinical trials. As with any wearable sensor, the quality of data collection depends on the amount of extra signal noise. Device fit, device usage, and motion intensity all affect the resulting accuracy. For a list of best practices, see related question: What are some best practices to help optimize for accuracy from wearables?

What are some best practices to help optimize for accuracy from my Garmin device?

Many factors may affect the accuracy of your wearable device for measuring physiological data, including the device fit and level of activity/motion. For this reason, we recommend the following tips: 

  1. Fit matters: Make sure all participants know how to correctly wear said wearable device.
  2. More samples, more insights: Collect extra samples and average them to get more accurate representations.
  3. Less movement, higher accuracy: Try to take measurements during low activity periods when possible, such as when one is sitting at a desk or sleeping.

What does Garmin’s Stress Level measure?

Stress Level is found on some Garmin wearables allowing a user to determine their current level of stress based on their Heart-Rate Variability.  For more information about how Garmin measures Stress Level, please visit https://support.garmin.com

 

What happens when Garmin devices run out of memory?
When you are logging data, especially if you are logging for multiple days or even weeks without syncing, eventually your Garmin device will run out of memory. When this happens all logging functions will turn off, and will not be able to resume until a sync with the smartphone is completed.
