Battery saving mode

What exactly does the surface book do to save battery aside from dimming the screen .?

I assume CPU performance is throttled...what I'm curious is would there be a noticeable impact on battery saving mode vs best performance when doing multi tasking with excel.. word. And several tabs browsing tabs open ?

Excel and word files aren't big...less than 1 mb each .l

Fyi have the i5 and 8 GB RAM
