Actually your battery savings will be minimal. This is documented by Apple as well on their website. The main drain for displaying graphics is the GPU and not the actual display. Turning on screen curtain or screen shade does not shut down the GPU, all of the graphics rendering is still happening, it is just not being displayed. You will save some battery by enabling it, but according to Apple the average user will not even notice the savings. I am also a Mac and iPhone user and have screen curtain enabled on both of my devices almost all of the time and my battery lasts about the exact same. With screen curtain off on my Mac Book I get 8 hours of battery, with it turned on the battery meter still reads 8 hours. Now that 8 hours also depends on what I am doing, reading email and word processing is much less drain than running a Win 10 VM in VMware Fusion. The main reason for screen shade/curtain is privacy.
