Moto g3 turbo edition got launched in late 2015 and I ordered one for my mother and I have also used it so here is my review about it.
It looks same as moto g3 no differences whatsoever.
However main difference is updated cpu and gpu, this is using SD615 octa core so performance and heavy gaming is good.
It also has turbo charger in box and it charges the phone very fast.
However phone gets warm due to SD615 chipset and battery backp is average.
