Battery drain during sleep

There is a same thread under Majove but I wanted to ask if the issue is known to Apple under Catalina. I use MBP 16 inch. I have parallel installed. In the Energy Saver settings, Power Nap is not enabled. This happened three times and I infer that the problem will persist. When I put the computer on sleep with the battery charged 100%, in the morning I see it is around 38% charged. I noticed that the bottom of the laptop was also a bit warm. Is there a solution? If this is not considered as a problem, what is the way of putting the computer truly to sleep like putting it a hibernate state which does not seem to be built in Catalina.
