I have Windows 10 installed on my MacBook Pro. I realized that Windows is using the dedicated GPU on the MacBook Pro, not the integrated one, which is using more battery than on macOS. (I use the MacBook mainly to watch YouTube and use Office.) Any help?
My specs:
Integrated GPU: Intel Iris Pro Graphics
Dedicated GPU: NVIDIA GeForce GT 750M
MacBook Pro 15", 10.14
The integrated GPU is hidden by the EFI layer on Macs when Window is installed. It is not an easy task to expose it and manage dual-GPU setup.

Yes.
And is there a purpose for this?
Windows dual-GPU support on Macs is problematic. Unless you must have it, I suggest sticking to the discrete GPU. If you are running out of battery, you may also look at Power Options -> Advanced Settings.
How long does your battery last on Windows?
On a new Mac, my battery lasts about 9+ hours using Dual GPU/WiFi and normal brightness/contrast. On Windows, it lasts 3-4 hours, without any changes. I normally change it to passive cooling and lower processor states, to make it last longer, ~5 hours at the most.

Ok thanks for your help. I just wonder why it wouldn't support the integrated one.
My Mac is still in good condition despite its age. I would say it lasts about 6+ hours with macOS with same settings. On Windows, probably about 2-3 hours.
A GT750m indicates a 2013-2014 15-in MBP.
Here's the battery info of my Mac at the time of this post:
The Battery looks fine. See Determine battery cycle count for Mac notebooks - Apple Support for reference.
OK thanks for your help. 👍
