I have a laptop that doesn't travel. So my options are to leave it plugged in all of the time or keep up the daily charging / discharging cycle. Google says that it isn't great for the battery to always be in charging mode, however the battery only has so many cycles and every day the battery takes a little hit if I charge / discharge. Is it better for the battery if I just leave it plugged in all of the time or should I unplug it during use and discharge the battery before charging it back up at the end of the day? Thanks.
