Jazzoo Posted March 26, 2021 Share Posted March 26, 2021 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 Dell 5450 EFI.zip Link to comment Share on other sites More sharing options...
