Don’t Wait for 100%
If you need a fast charge, waiting until the battery reaches 100% could be a mistake. This is because Apple designs its batteries to fast charge all the way up to 80%, and then slowly charges the remaining 20%. This helps keep the battery healthy, but it also means the last fifth of charging takes much longer. If you want the speediest results for this charge, just unplug around 80%.
