After installing 12.23 I had slow GPS fix times, less accurate GPS tracks and other various small issues.
Performing hard reset followed by full device reset fixed all issues for me. Now my Forerunner 955 is getting GPS fix quickly as before 12.23 and the GPS tracks are very smooth and accurate! Overall the watch is performing as expected and I don't see battery drain. Re: battery consumption, you need to wait 2-3 days to stabilize. It is not a matter of consumption, but how acurately the level is indicated.
1. To perform a hard reset, press and hold the power button on the watch until the screen goes blank. Ignore the Controls menu and the assistance alert screen (if applicable). If your device is currently powered off and you cannot turn it on, simply hold down the power button for 60 seconds.
Next, plug in your watch’s charging cable to a computer or UL certified wall plug and then attach the watch to the charging cable. This should prompt the watch to boot up normally. Once it has fully booted up, remove it from the charging cable.
2. To perform full device reset, please see the link below for instructions:
First, sync your device with the Garmin Connect mobile app or Garmin Express. Then follow the instructions in this link:
Resetting All Default Settings
- Choose the "Delete Data and Reset Settings" option.
Note that you will need to customize your watch again, some settings will be lost (like Garmin Pay, etc.).
Use at your own risk!
