Greetings altan291,
To help isolate the behavior and see if power is being drawn unexpectedly, test if the issue occurs when all peripherals are disconnected from your Mac. Additionally, test if the issue occurs when Wi-Fi and Bluetooth are turned off prior to sleep.
You can see how to turn off Bluetooth here: Turn Bluetooth on or off on Mac - Apple Support
"1. On your Mac, click the Bluetooth status icon in the Control Center or menu bar. If you don’t see the Bluetooth status icon in the menu bar, choose Apple menu > System Preferences, click Bluetooth , then select “Show Bluetooth in menu bar.” Bluetooth is always available in Control Center.
2. Click the switch to turn Bluetooth on or off."
You can turn off Wi-Fi from the menu bar: Use the Wi-Fi status menu on Mac - Apple Support
"Turn Wi-Fi on or off
