It appears that when I’m wearing a different watch and that Apple Watch is connected to my iPhone and I have my ultra charging, it doesn’t fast charge. I’m running watch OS 9.3.1 on my ultra. Anyone else having a similar issue?
Apple Watch Ultra
Apple Watch Ultra battery level can go from 0 percent to 80 percent in about an hour.*
* Apple Watch Ultra, Apple Watch Series 8 (GPS), and Apple Watch Series 8 (GPS + Cellular) battery life testing was conducted by Apple in August 2022 using preproduction Apple Watch models each paired with an iPhone; all devices were tested with prerelease software. Battery life varies by use, cellular coverage, configuration, and many other factors; actual results will vary.
