Recently I did an orderly shutdown of my laptop while it was plugged into mains, and battery fully loaded.
Six days later I tried to switch it on again, and it was not possible. After connecting to mains, I found the battery sucked dry at 0%.
Then this article here (which seems no longer present now) brought me to the idea to check that:
I let the battery charge to 100%, then did an orderly shutdown.
When restarting after 24 hours, the battery was at 75%.
Now I did a hard poweroff, pressing the power button for 10sec.
After another 24 hours the battery was at 72%, which now looks much more practical.
