Dell 5450: Battery Problem in Big Sur

Hi guys! Recently I installed MacOS Big Sur 11.2.3 and everything works just amazing but the battery life is terrible. Before Big Sur I was on Mojave 10.4.6 and the battery life was between 4 and 5 hours and now I can barely get 2 hours. I used @Jake Lo's OpenCore EFI from 7450 guide and thanks to this man the machine is rock solid. Is there any fix for the battery drain? Any help is appreciated. Cheers
