Hackintosh battery life

[hackboy22]

Hello everyone! I'm running macOS Mojave 10.4.4 and everything works fine, but I noticed that in Windows the battery lasts for 4 or 5 hours, instead in macOS it lasts for only 2 hours. I've also changed the WiFi card with the BCM94352HMB, as FAQ recommends, and turned off the Nvidia graphic card (of course), but macOS still drains battery more quickly than Windows. Why? Is there a way to avoid this problem?
I thank you all in advance.

Hey , can you please tell which laptop do you have?and how did you fixed graphics on mojave ??
Thanks
