Laptop battery suddenly drains fast after update

Since the latest Windows update, my laptop battery life has taken a nosedive. It used to last around 6 hours on a full charge, but now it barely gets to 3. I've checked for any background apps eating power, disabled unnecessary startup programs, and even recalibrated the battery, but nothing has helped. I’m running Windows 11 on a Dell XPS 13, fully updated other than the recent patch. The battery health seems fine according to the diagnostics tool. Could this update have messed with power management settings or drivers? Anyone else experiencing this or have a fix? Would appreciate any tips on how to troubleshoot or roll back the update if that’s the issue.
