Power save settings
The power save settings allow you to extend your training time by changing the GPS recording rate or setting wrist-based
heart rate off. These settings let you optimize battery usage and get more training time for extra long sessions or when the
battery is running low.
The power save settings are found in the Quick menu. You can access the quick menu by choosing Settings from pre-
training mode and during a session when paused.
After setting on any of the power save settings, you'll see their effect on the estimated training time in pre-training mode.
Note that the power save settings are set on for each session separately. The settings are not stored.
Note that the temperature affects the estimated training time. When training in cold conditions the actual
training time can be less than what is indicated when starting the session.
GPS recording rate
Set the GPS recording rate to a less frequent interval (1 minute or 2 minutes). Handy in ultra-long sessions when long
battery life is essential.
Note that changing the GPS recording rate to a less frequent interval may reduce the accuracy of other
measurements, such as speed/pace and distance, depending on the sport profile and sensors used.
Wrist-based heart rate
Set wrist-based heart rate off. Set it off to save power when you don't necessarily need heart rate data. When using a heart
rate monitor with a chest strap wrist-based heart rate is set off by default.
Energy sources
The energy sources breakdown shows how much of different energy sources (fats, carbohydrates, proteins) you used
during your session. On your watch, you can see it in the training summary right after finishing your session. More detailed
information can be viewed in the Flow mobile app after syncing your data.
During physical activity, your body uses carbohydrates and fat as main sources of energy. The higher your training
intensity, the more carbs you use in proportion to fat, and vice versa. The role of protein is usually quite small, but during
high intensity activity and during long sessions your body can use about 5 to 10 % of its energy from protein.
