battery draining issue after installaiton of windows 11

Yes, i am using HP pavillion gaming laptop, Now I got stuck in the unlucky category who missed downgrade to windows 10 after days, Coz after updated to windows 11 I got realised my battery draining issue after 2 weeks, My battery is lasting less than 1 hour, even in the battery saver mode it's draining like a water, I have raised a case against HP for battery issue, Though they have provided me a new replacement battery still it is draining at top speed, Microsoft please fix this issue ASAP
