Yes, a Control Center button (maybe incorporate it into the same button that is used to enable low power mode?) would make this feature MUCH more useful. As it stands now, I leave mine on 80% because I work from home most of the time and this is way more than enough to get me through a day. But if I know I'm going to have a work day out in the field, or will be doing recreational stuff, and want 100%, it's quite a few taps into the settings to switch it.Since I’m at a desk most days with my phone near a charger almost all the time, I love this feature. I just wish there was a quick button to press to charge to 100% when needed.
