History contains up to ten previous activities you have saved on your device. When auto upload is turned on, your device automatically sends your saved activities and daily activity tracking data to the Garmin Connect™ Mobile app (Using Garmin Connect Mobile).

Your data storage depends on how you use your device.

Data Storage	Mode
Up to 2 months	Activity tracking only.
Up to 2 weeks	Activity tracking plus extensive fitness activity use. (For example, using a paired heart rate monitor for 1 hour per day.)

When the data storage is full, the device deletes the oldest files to make room for new data.
