Macbook Pro 13" 2020 Battery drains to 90% despite being plugged in to the charger

Hello, I just recently started using my Macbook Pro 13" 2020 a few days ago. And for some reason, I noticed that for 2 nights in a row, the battery would drop down to about 90%? and it will charge back up to 100% again... But I find this very odd because I almost never take the laptop off the charger. So why would it loose battery when it's on the charger? I also had this laptop custom built to how I want it too... And I am also on the latest 10.15 OS too...

MacBook Pro 13″, macOS 10.15

This is the new normal—



macOS Catalina 10.15.5 introduces battery health management, a feature designed to improve the lifespan of your Mac notebook's battery.


The Battery Health button appears in >SystemPreferences>Energy Saver —this feature is limited to Mac laptops with Thunderbolt 3 ports. That equates to all MacBook Pro models released since late 2016 and the Retina-capable MacBook Air models released since 2018.
