Fenix 7 Battery Life - Losing 20% in 12 hours

I’ve had the 7 sapphire solar for a couple of months now. It has the latest software update and I don’t have real time HR on my main screen.  No other apps installed. I charged it yesterday evening at 630pm and by 9am this morning it is down 20%. 

I don’t have it doing pulse ox readings. What the heck can be done?
