If you were storing a laptop, it would best be at 50% or so. The battery is under less stress at that state of charge (SoC), so the battery will age more slowly. 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.
