On a day where I don't use Garmin Connect, my Pixel 4a 5G will stretch to two days' battery life. If I do use Garmin Connect with my Edge 830, the battery drain continues apace even when a ride is over and Garmin Connect remains at the top of my battery usage list for the rest of the day or until I force stop Connect or reboot (my battery will not last a single day after a ride if I leave it going).
This only started happening when I upgraded from Android 11 to 12 last week.
Is there a known issue with drain under 12?
