Finally tested with another shifter. Its 100% the left shifter thats draining. I can do two things from here:
-Buy a new LH shifter
-3D print a bar-end plug that has a switch glued into it, spliced into the Di2 cable that goes to the left shifter. This way I can disconnect the left shifter without much hassle when I get back from my rides.
