Hi,
I have a MacBook Pro 2018, if I work for the day with the power adapter plugged in and switch off at 100%, when I try to tun on the following morning it will be completely dead, 0 Charge.
Can anyone advise? Battery condition is 'Normal' in the battery health section.
MacBook Pro 13″, macOS 11.3

How battery health management helps
The battery health management feature in macOS 10.15.5 is designed to improve your battery's lifespan
by reducing the rate at which it chemically ages.
The feature does this by monitoring your battery's temperature history and its charging patterns.
Based on the measurements that it collects, battery health management may reduce
your battery's maximum charge when in this mode.
This happens as needed to ensure that your battery charges to a level that's optimized for your
usage—reducing wear on the battery, and slowing its chemical aging.
Battery health management also uses the measurements to calculate when your battery needs service.
