Same issue here. With battery performance selected in Windows 11, I’m only getting around 3 hours. It’s normal regardless of what the Dell “helpers” claim. It doesn’t matter what drivers you install, I.e., Dell, Intel, or Windows, you can tweak your system hear and there but we’d be foolish to believe you’ll get an additional few hours. MS Edge is a resource hog though. Anyway, 3 hours is the real number with real use. The only way to extend your time is to set it down a stare at it!
