Battery Life, Power Consumption & Portability Index
Battery Life & Power Consumption
Intel has claimed that its new fourth generation Core processors are its most efficient processors ever and said that notebooks can expect to see as much as a 50% increase in battery life. Bold claims, indeed.
Usually, we use Powermark to determine the battery life of a notebook system, but for unknown reasons, Powermark refused to run on the MSI GE40. As a result, we had to fall back on our previous testing methodology, in which we looped a high-definition video clip over and over until the notebook ran out of juice. From our extensive testing experience, we've found found that both testing methods will net somewhat comparable results.
The MSI GE40 has a decently-sized 65Wh battery pack and we found that it could run nearly 7 hours, which is impressive, far exceeding any of the other gaming notebooks here. Calculating its power consumption, we arrived at a very low figure of just 9.47 watts, which is just half that of its competitors. Based on this, it seems that Intel has delivered on its promises and claims. The new fourth generation Core processors are truly its most power efficient yet!
Our Portability Index factors in battery life, weight and volume so you can see which notebook is the most worthwhile to carry around. As you can clearly see, its portability index score far exceeds that of any gaming-class notebook and is a rival for Ultrabooks.
