Battery issues 5X+

When I first got my watch in April, I was at a 3% drain every 24 hours when not tracking activities. Now with 8.40 I am up to 5%. When I do something like walk without setting it as an activity and I look down at my watch, it gives me a watch face of IQ!. 

How can i roll back to the factory install of software on my Fenix 5x Plus. These upgrades have only screwed up what was working fine.
