Battery Life & Portability Index
The Y500 gets its juice from a 6-cell 72Wh battery. Compared to the rest of our machines, only it and the HP Pavilion DV6 utilize a 15.6-inch screen size. The Y500 is also the only machine in our setup running on Windows 8, which some evidence from our past testing suggests is less power consuming than Windows 7.
While the SLI config doesn't work properly when running on battery, we thought it would be interesting to see if it made any difference to overall battery life.
With the optical drive installed, the Y500 managed to last a very impressive 3 hours and 28 minutes, far surpassing the rest of our machines. Surprisingly, even when not in use, the second GPU module made a huge difference in battery life, knocking 50 minutes off of the Y500's total battery life.
Power consumption was excellent with the optical drive installed, and still better than most of our 17-inch gaming notebooks even with the SLI configuration.
Our Portability Index factors in battery life, weight and volume so you can see which notebook is the most worthwhile to carry around. Predictably, the smaller Y500 was much more portable better than all of our 17-inch gaming notebooks and was generally on par with other 15.6-inch multimedia machines like the HP DV6 or Samsung RF511.
