About two weeks ago, I notice if I use battery, my MacBook battery status will stay 100% usage for a long time, and then out of power at 64% (shut down without any battery warning).

The effort have tried so far:

• reset SMC many times
• Set AlDente to maximum and then uninstall
• Update to 2.1.2 and then redo above trials
• Reinstall macOS and reset SMC again

Still not working.
I use MacBook Pro 2017,
BigSur 11.2.3.
64% is the threshold I used to use.
