Avoid batteries at 100% -- battery charge management

The longevity of batteries greatly goes down when full charge is maintained. Mobile operating systems have implemented new strategies to slow down or delay charging the last 20% to minimze the time batteries are at full charge. Because laptops are frequently "plugged in", retaining a 100% charge may be very detrimental to battery health.

We should investigate different strategies and look into a better 'battery longevity' approach. Needs design.
