My old 2015 MacBook Pro without a discrete GPU had amazing battery life. I'd get at least 8 hours, and over 10 if I wanted to sacrifice some of the brightness and turn bluetooth off. I got upgraded to the discrete GPU model and I could get at most 6 to 7 hours for the same workload.

Nowadays, you can't even get a 15 inch MacBook Pro without a discreet GPU.

You can stop the OS from switching to the discrete GPU using an app like gfxCardStatus
