Hi, thanks for sharing this information about the issue you're experiencing with your Charge 5, @Kernow55. 

Keep in mind that if you use built-in GPS continuously, Charge 5 has a battery life of up to 5 hours. However, since you also mentioned that you do see battery life remaining after the device turns back on, please try completing the three pulse restart as well and let me know if you continue to have the same problem afterwards: 

1. Connect your device to the charging cable. For instructions, see How do I charge my Fitbit device?
2. Press the button located on the flat end of the charger 3 times within 8 seconds, holding each press for about 1 second.
3. Wait 10 seconds or until the Fitbit logo appears.
4. If the device doesn’t restart, wait 15 seconds to try again.
