M1 battery stored at 50%. When started up it's 0%

All batteries slowly discharge over time for a couple of reasons including the chemical reactions inside the battery that create electricity still happen even when the computer is off.

Double check that the option wake for network access on battery is off.
Unfortunately that's not how AlDente works (or can work). The app has to actively run.
Before sleeping, AlDente can block further charging. But not keep it at a.e. 50%.
It cannot prevent the MacBook from slowly discharging over time unless the MacBook wakes up periodically.
And on Apple Silicon, when the MacBook has been powered off, AlDente cannot block charging at all:
When your MacBook is powered off, apps cannot run and make any changes. Therefore, AlDente is not able to make any changes to the charging behavior of your MacBook while it is powered off. As a result, your MacBook will always charge to 100% when it is plugged in and powered off, regardless of the set Charge Limit in AlDente. Due to Apple Silicon MacBooks resetting internally when they are shut down, it is not possible to stop or limit charging when they are shut down. The only way to avoid letting your MacBook go to 100% is to not shut it down and let your MacBook go to sleep instead or to unplug it before you turn it off.
ADD: On Intel MacBooks, when you enable "Stop charging when powered off" and the battery drains to 0%, you cannot charge/boot the Mac anymore unless you perform a PRAM reset.

Something simpler is a mechanical or electronic outlet timer to control how long it charges instead of the percentage it charges to. For example, fifteen minutes per day should keep it at a low percentage.
Yes, it would work. Just turn off the screen and you will be fine. No need to close the lid.
Just curious, did you shut it down by choosing the Apple menu `Shut Down...`, or just closing the lid?
I'm starting to think that Apple Silicone Macs has some sort of new battery management in-place when shut off. My old 2015 rMBP discharged very slowly when turned off and unplugged, could sometimes go 2+ weeks while still being at 100%. But my new 2021 16" seems to discharge much faster, ~1%/day. I thought it was aiming for 50%, but judging by this thread I guess not..
