In fact the iPhone 11 Pro can only charge up to 80 is not a malfunction because the Optimize Battery Charging feature is not turned off. For most people this will be around 2 years for the iPhone. Your iPhone will charge again when the temperature drops.
Wondering why your iPhone is not charging after 80 percent.
Try moving your iPhone and charger to a cooler location. To extend the lifespan of your battery if the battery gets too warm software might limit charging above 80 percent. If your iPhone is not charging to 100 you may notice that it remains at the 80 threshold or something close to that like 83-84 for me. With iOS 13 and later Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged.
