Intel Browser Battery Life

Up next are results using the Gateway NV58, which uses Intel's GM45 + ICH9M chipset with integrated GMA 4500MHD graphics. Again, we use Vista's "Power Saver" profile instead of "Balanced".

The graph is about the same as the Gateway NV52, but the standings are slightly different. In testing, the T6500 processor ends up around 25% faster than the QL-64, so it could be that the Intel setup is able to run at lower power states more than the AMD laptop. IE8 once again comes out on top, this time leading Chrome by 4.1% and Firefox + AdBlock in by 2.25%. AdBlock manages to provide a 5.7% boost to battery life over vanilla Firefox.

Each browser setup is slightly better than the one below it, typically by just 1% to 3%, but taken together IE8 provides 8% more battery life than Firefox 3.5.2, Opera 9.6.4 beats Opera 10 by 5.5%, and Opera 10 leads Safari 4 by 9.2%. Safari 4 under Windows is again the worst solution for battery life, perhaps because it doesn't handle Flash content as well as the other browsers. CPU usage is definitely higher under Safari 4 with our test websites, and it trails the best option by 23%.
