Your drain over a reasonable period for example unplug your laptop and shove in into a bag and take it out 1-8 hours SHOULD be relatively small.

However the internet is seemingly full of complaints that machines drain fast during sleep so your experience may not be unusual but it might pay to check if something is wrong or at least sub-optimal. For example GPU not actually turning off, usb device keeping it from sleeping, hardware or software waking up your machine.
