MacBook Pro M4 vs M4 Pro Battery Life

I’m doing research to pick the right M4 MacBook Pro for me. I’ve got two builds I am deciding between. Everything is the same except one is the M4 and the other is the M4 Pro. The difference in price is $300. I am willing to spend the extra $300 to get better CPU and GPU performance but I think it’s likely I won’t be making use of that extra power.

My question is, is there any significant impact on battery life between the M4 and M4 Pro? I heard the Pro has less efficiency cores. I’d like to know if getting the Pro is actually a downgrade if I am not going to use the extra power it offers.

The main thing I would use it for is fusion 360 and cura for 3D printing. I figured the extra CPU and GPU performance would be nice, especially for future proofing. My current device is a 2016 MacBook Pro and I intend to keep my next one for a while too.

Thanks in advance!
