Forerunner 255 rapid battery drain overnight

over 2 years ago

A few weeks ago watch was at 60% at night when I went to use it, watch was dead.  

2 days ago checked watch at 8pm watch at 73%,  yesterday went to gym watch was at 8%.  This is a serious problem.   I had a 245 and never encountered this.  

Last night I made sure my phone was by my watch to see if it is something with syncing.   It was at 85% after a full charge earlier in the day and not using any GPS.

Now it is at 48%,  since yesterday at around 1pm, this is way to inconsistent

    Have you tried the following:

    1. Forget the device on the phone BT settings

    2. Remove teh GC app form the phone completely

    3. Long press on Light to power down the watch (keep pressing until it powers down completely)

    4. Shutdown and restart the phone

    5. Restart the watch

    5. Reinstall the GC App and log in

    6. Select Pair on the watch

    This helped to sort some issues my side with the 955 , maybe it will assist.

    60% to 30% overnight with only phone off.

    Hope it is a coincidence, since it was ok two nights before.

    • If there was a functionality to set the watch to auto stdby during sleeping hours would be super nice.
