Marq Aviator: Extensive battery drain on a new watch

I bought a new Marq Aviator about 2 months ago. Optically and functionally it's a great watch, no doubts. I'm a private pilot and noticed several improvements compared to my previous D2 Charlie in terms of flying functions. However, I think that something is off with the battery or hardware of my Marq Aviator.

Since the beginning I noticed that the battery endurance was lower compared to my D2 Charlie. Initially I thought that it needs a few more charge cycles to reach the advertised values of more than10 days. However, after ~2 months the situation even worsened.

With the latest firmware 16.70, even after several factory resets and without any extra widgets, SPO2 etc., the battery drain is about 25% per 24h. 1h of GPS activity without music drops the battery by another ~10 percent.

I'm wondering what is the experience of other owners of Marq Aviator w.r.t. battery endurance.

Hi, the outcome was that Garmin replaced my defect item. The new watch now finally shows battery endurance of more than 12 days :)

Long term average of 0.27% per hour. Not using Navigate function. O2 sampling only if I manually trigger it. No music.

I have the same experience with my Athlete. Battery life is not good at all on the Marq, especially compared to Garmin Fenix 6x.

Not only do you have to remove the SPO2 widget, but you have to actively disable the SPO2 sensor.

SPO2 is disabled in the settings. I already contacted Garmin Support. They asked to try one more time soft and hard reset which I did. Unfortunately the reset didn't help. The next step would be a replacement.
