Battery Drain on MacBook Pro while in Sleep

I have a 2020 MacBook Pro on Sonoma 14.4.1 that is experiencing significant battery drain every night on Sleep Mode. I charge the MacBook Pro to full during the day before Sleep, but then overnight the battery will drain to 0% and I have to recharge and restart the computer every morning. When I look at the overnight Battery Level in System Preferences, I see that the computer experiences a gradual battery level decline, a sharp battery level incline due to charging although my laptop is not connected to a power adapter overnight, then a gradual battery level decline again. I am unsure why the Battery Level fluctuates so much and why it says the computer is charging when it is not connected to a Power Adapter.

• Battery Health is Normal.
• I am not using Power Nap.
• I cannot find or turn off Screen Time since it is unavailable in the sidebar of System Preferences (Screen Time Not Showing Up - Apple Community)
• I have the latest MacOS version.
