There seems to be an intermittent bug in Garmin Connect that causes extremely high idle power draw. I am unsure what causes this, but the only resolution I found was to restart my phone. Closing the app doesnt resolve this issue.
This has happened on an Samsung S25 Ultra with a Garmin 265 as the only connected device. My partner with a similar setup has also had this happen once.
When this bug occurs, I noticed because it drains approximately 15-20% an hour and my phone becomes very warm despite being idle.
The normal Garmin connect consumption is typically less than 0.2% on most days which is more inline with what I expect.
The application and watch firmware is up to date, and this bug has been here for many months.
