Sorry, I am at work so cant write long responses... I did do the usual fixes such as clearing caches, disabling background services, I even went through and turned off many of my background location services. I did this for both the main system and for knox.
My play store percentage use was 26% of background usage and the time matched how long the phone had been off the charger.
I just reset the play services data, there was about 9GB of data stored in there, so I guess I will see if that works.
I even tried to rollback the play services to an earlier version but I click the button and nothing happens, even though it isnt greyed out.
So, the data delete from play services didnt help any... I think I'm running out of options
