XPS15 owner here. Had this exact problem during the first year of ownership. Somehow Windows updates changed this behavior and I haven't had any more battery draining / overheating in bag since. But I will not buy Dell again. Too many little problems. I haven't had ONE problem of this kind with ThinkPad's, in maybe 25 years of use.
