Fenix 6x battery has drained rapidly since updating to 26.00, heart rate sensor also no longer flashes green instead it is a solid red light, any idea what's going on?

My watch won't hold charge for longer than 6 days now, and has only occurred since the update. 

Also noticed that the normal green HR sensors do not flash anymore, instead it is a solid red light. Pulse Ox is turned off so it isn't this. I have done a hard reset of the device and doesn't seem to help.
