    I am sorry to hear you are having this issue. For this, after completing the activity, have you tried a hard reset? For this, hold the Light button until the watch shuts off, as opposed to selecting power off. Then power on again. Does this end the increased drain? 

    Our engineers are still investigating battery drain concerns associated with the Fenix 8. They would like to point out many things that are expected to increase battery drain beyond the estimated days remaining. This could include any of the following: 

    • GPS (in particular All satellites, or Multiband settings will use more battery life)
    • Voice Features
    • Phone assistant
    • Backlight (It is recommended to reduce the brightness. Gestures will turn this on more frequently)
    • Notifications
    • Alerts
    • Vibrations
    • Animations (as with yoga or breathing activities for example)
    • Connect IQ apps or watch faces (many of these have been found to drain the battery more quickly)
    • Pulse OX either All day or During Sleep
    • Paired sensors
    • Music
    • Paired Bluetooth headset
    • Watch faces with second hands

    So when you are measuring your battery drain, be sure to take these items into account. If you are seeing a rapid drain outside of these uses, please feel free to reach out to me via Private message so I can collect some details.
