A Comment on PC Gaming Battery Life
During the process of writing the Razer Edge review, I spent a lot of my time gaming on battery. The Edge is marketed as being a mobile PC gaming console, and is pretty well suited in that role with one caveat - battery life. Razer quotes 1-2 hours of gaming battery life on the internal 41.44Wh battery, with those figures doubling when the extended battery is inserted in the gamepad controller. The range makes sense; playing Angry Birds would be understandably less strenuous than, say, Skyrim or Crysis.
In real-world testing that holds up - I saw just over two hours of Dirt 3 playing time, and around 3.5 hours when playing the decade-old Quake III: Arena. But something I missed was that Jarred had actually developed and done some repeatable, instrumented gaming battery life testing in his preview of the ASUS N56VM, one of the first systems we tested with the mobile Ivy Bridge platform. I canít honestly remember why we didnít put more systems through this test, but such is life.
The test itself is pretty simple: looping the four 3DMark06 gaming tests at 1366x768 in the balanced power profile and the display set to 100nits, with the GPU specifically set in the balanced performance setting (usually by default on battery itís set to maximum battery saving except in the High Performance profile). Jarred ran the test on the N56VM twice, once with the HD 4000 and once with the Fermi-based 40nm GT 630M that our international-spec N56VM test unit had, as well as the Sandy Bridge-based ASUS K53E (i5-2520M and HD3000) and the Compal-built AMD Llano reference platform that we looked at way back in June 2011.
Naturally, my first inclination was to run it on my Edge evaluation unit - so I did. Twice, in fact, both with and without the extended battery. I also had a Sony VAIO T13 ultrabook on hand, a pretty run of the mill entry-level ultrabook from summer 2012, so I ran that too. The spec rundown: i5-3317U, HD 4000, 4GB of memory, 500GB 5400RPM hard drive, 32GB SSD cache, 45Wh battery, a mostly terrible 1366x768 13.3Ē TN display, and Windows 7. Advance apologies for not having a more recent AMD-based system in this comparison, ideally Iíd have a Trinity system to compare against but Iím on the road and had to go with what I had near me.
