Comment 233 for bug 760131

Current way of rendering the GUI is dependent on CPU power, so battery on stronger processors runs longer, why, because the stronger CPU needs less time to render the GUI, it's just like in vehicles, as vehicle has more horsepower it consumes less fuel, because it takes less time to achieve the speed, and because GPU is 10 times stronger than CPU, battery on Windows lasts more. In Linux we hardly have Open GL 1.5. support. So, I think even in this stage Wayland should be the default server on Ubuntu because of this.
