Setting a D2, fēnix, quatix, or tactix for Longer Battery Life or Greater Detail

The fēnix® watches, as well as the tactix®, quatix®, and D2™ watches, offer an UltraTrac™ mode for extended battery life while recording longer activities. The UltraTrac feature is a GPS mode that by default decreases the update rate of GPS data to once a minute, providing up to 50 hours of use in ideal conditions. Normal GPS mode on the device will reduce battery life, but offer a more detailed track for the activity. 

All ANT+ sensors will be disabled and stop recording while the device is in UltraTrac mode. However, at times ANT+ sensor data may be recorded while the devices records a GPS track point.

Maximizing battery life and detail

1. Press the Action key
2. Select Setup
3. Select System
4. Select GPS Mode
5. If activity is over 24 hours, select UltraTrac
6. If activity is around 8 hours, select Normal
7. If activity is greater than 8 hours:
   1. Select Normal
   2. Press Back
   3. Select Tracks
   4. Select Time for Method
   5. Select Interval time¹
   6. Select Done

Adjusting the settings on your watch will provide you with a good balance between battery life and track detail.

¹ Setting the update rate to 15 seconds will provide approximately 20 hours of tracking, while setting it the update rate to 20 seconds should provide greater than 24 hours of tracking time. Results will vary based on tracking conditions (heavy tree cover and other things like terrain and buildings can decrease the battery life faster).
