I actually tested this a little on a Nexus 5X a while back. With a clean install of a LineageOS build manually patched to include microG (before I knew about this fork), I unplugged it from the charger at 100% and left it for 8 hours without using it, at which point the battery read 98%. The same device with a clean install of stock Android from Google read 87% after 8 hours of standby after a full charge. In both cases it had good LTE signal and had no modifications from a clean install other than signing into a Google account.

It is a bit entertaining to think of Google's surveillance quantified via electricity - we can measure their intrusiveness in mAh.
