Yeah, and I don't do any of these things. I just get notifications from my watch and use it as a remote control for podcast playback/ffwd (from my phone to my AirPods). And I have AOD turned off.
The "up to 13 days" number is based on a specific set of behaviors/usage, [1] and the Garmin support people have not been able to explain why I'm not getting it. They have looked at logs for my device and have been content to say that 60% of the "up to" number is normal for their devices.
I was hoping for much better, especially considering the Verge's reviewer [2] said she was getting 6.5 days with AOD turned on, and was on track for 15 with it turned off. I wonder if she was given a bespoke unit by Garmin, which is better than the ones that we get in retail stores.
