Same issue with my 6S. Before Downloading iOS 14.1, I had great battery life. Since downloading iOS 14.1 my battery drains super fast. I’ve shut down all background apps, changed general and app settings to preserve battery life, and powered off/on. The battery still drains even when essentially not running anything. This battery drain issue is ridiculous and needs to be fixed ASAP! No one wants to have to charge their phone every couple hours.
