Rey Ian Cabanganan shared a handy Siri Shortcut over of the Siri Shortcuts Facebook group which does a good job of optimizing your phone for “fast charging”. Now, obviously, none of the charging technologies is changed using this shortcut. It simply switches off all of the battery intensive functionality on your device. What’s more, to save you the effort of having to switch all the services back on, it will prompt you in 30-minute intervals, so once your battery has reached the required percentage it will switch them all back on again.
Ian appreciates his device knowing who is boss and has added voice acknowledgement of his status. I’ve removed those sections, the rest I’ve left in place.
