Many people keep their laptops plugged in and charging when using them at home, and rarely if ever take them out of the home. This keeps the Lithium battery at 100% State Of Charge (SOC), which I understand shortens the battery life. It would seem to follow that the battery life could be optimised if there were some way of selecting "storage charge" on the laptop, whereupon the charging circuit would keep the battery at 50% SOC. This issue has become more pressing now that manufacturers have switched from removable Li-Ion battery packs to built-in LiPo battery packs. I'm guessing that all the necessary hardware is already present, and so this would be a relatively simple software fix. Is this an issue that has already been addressed and for which a solution is already available?
