Fenix 7X Pro - Battery issues

What in the world is happening to my brand new Fenix 7X Pro? Battery is draining like insane. It lasts less than my Epix Pro 51mm. So, I did a test and put in the drawer my Fenix 7X, Enduro 2, and brand new Fenix 7X Pro. All three on latest firmware v13.22. I charged all three to 100% and rebooted them and went on a trip and came back 5 days later. Enduro 2 and Fenix 7X are at 91-92% but Fenix 7X Pro is at 75%. No third party Watch faces, no apps except the battery widget. I even hard reserved and forced new update from secret menu multiple times but nothing helps. Pulse ox is off and no Bluetooth connection to phone. See attached photos. On the left is Fenix 7X Pro, on the right is 7X normal, middle is Enduro 2.
