After a while, clicking on your battery icon will report "Battery is not charging" if you have more than ≈73% left, even though your charger is connected. Notice that in this state, your MacBook is still powered by the charger, but the battery is not charging anymore. IMPORTANT: Keeping your battery at a lower percentage, such as 20-70%, over weeks without doing full cycles (100%-0%) can result in a disturbed battery calibration. When this happens, your Macbook might turn off with 40-50% left or your battery capacity will drop significantly. However, this is only due to a disturbed battery calibration and not because of a faulty or degraded battery. To avoid this issue, we recommend doing at least one full cycle (0%-100%) every month. Even if your battery calibration gets disturbed, doing 4-5 full cycles will recalibrate your battery and the capacity will go up again.
