The only C++ M1 time and battery benchmark I remember is from Matthew Panzarino[1]. He found that it took the M1 Air 25 minutes to do a fresh compile of WebKit, and that the Air had 91% battery remaining after finishing the compilation.

So, roughly assuming that you could compile WebKit 10 times before the laptop runs out of juice, that'd give you 4 hours 10 minutes of battery life.
