I'm not in a minority, this is something that's a new and common complaint among iPhone users. The performance of iOS 26 is very bad. Look at the huge recent spike in "iPhone battery problems" in Google Trends shortly after iOS 26 released, hitting its highest-ever in January 2026. The last peak was in 2011.
