After reading through this thread, I implemented a few suggestions from various posts with success. Will re-post here if the results change within 24 hours, but first run through worked to bump my battery back up. After implementing these changes my battery went from 43% to 97% when I turned the phone back on: Turned off Background App Refresh  Turned off Auto Brightness in Display settings and Accessibility  Turned Off Siri Completely Went to Settings, Battery and toggled OFF "Battery Percentage." Then I scrolled down and selected Battery Health, and toggled OFF Optimized Battery Charging. Then I did a hard restart of the phone, went back into the Battery settings again and turned Optimized Battery Charging back ON and Battery Percentage back ON Good luck, everyone! Hopefully we won't be FORCED to get new phones during these trying times....
