Pause Function to Save Battery

I have Tomtom Spark 3. The battery can only stay for 6-7 hour full biking activity. It's not enough for me.

Is it possible to set an option to stop the heart sensor and GPS while the activity paused?

Thanks you.

    The HR sensor and GPS do stop when you pause. they go into standby mode to save battery. 6-7 hours is about the expected life for the watch, particularly if you have had it for awhile. If you use an external strap or turn off HR altogether it will extend the battery, Battery life for a new device is rated for around 5 hours for GPS/HR/Music, 9 for GPS/HR, 11 for GPS only, 2 weeks for watch only (that includes pause time as the sensors are still on - so if during a 2-hour activity you had 30 minutes of pause it was 2:30 of battery life, not just the 2 hours it was recording for). Those of course are estimates and best-case scenario and are impacted by usage (using backlight, switching screens, etc.) and environmental conditions (overcast skies, tree cover, tall buildings, etc.). If you have night mode or the backlight on that is going to impact it greatly. I have found that they are accurate estimates and my usage and testing has matched them. Bear in mind that the battery gauge is a rough estimate at best and I have gone many hours when it indicates that it was almost empty.
