I did a short experiment which told me what I needed to know, I haven't got mass amounts of time to do in depth tests so I did this.
Charged my Moto G up to 100% with lowest screen brightness, volume muted, put it in aeroplane mode and played Blocky Roads for 3 hours at 3 different clock speeds, 30 mins with normal graphics and another 30 mins with GLTools halving the screen resolution and texture resolution.
This was my result.
30% an hour at 1190 mhz = 3 hours 20 mins total gaming time
18% an hour at 600 mhz = 5 hours 30 mins total gaming time
12 % an hour at 384 Mhz = 8 hours 20 mins total gaming time
I then did it with the lowered graphics and found it didn't change a thing, BUT! It was very useful for making the lower clock speed game play more playable and I will be using it for just that!
