To be fair, charging your notebook at 100 all day is going to degrade the battery pretty quick. Using it unplugged until it's low is actually the correct procedure.
This can be changed in software, setting it to 70-80% or having a toggle is best for the battery.
If you have OSX, you can use Al Dente[1] to limit SoC to 70 or 80% while using it to reduce battery aging. There may be similar settings on Windows depending on your laptop's manufacturer.
If you can maintain a limited SoC rather than running the battery down, that's most preferable.
Otherwise, discharging lightly (but not below 20% or so) then charging to 80% or so would be a good usage pattern.
It's helpful to know that many chargers are designed to achieve 1C charge rate (this excludes "fast chargers"). That essentially means they go from 0 to 100% SoC in one hour. So start a 30 minute timer when you plug in electronics to charge, and you'll gain about 50% SoC.
