Do you have a laptop or netbook with average or poor battery lifetime? If that’s the case, you might want to use an Internet browser that’s able to take advantage of the power saving features included with Windows 7 or Windows 8. 7tutorials tested all the major browsers and had some very surprising results.
Internet Explorer isn’t the fastest or most featured-packed browser around, but it might be the most power efficient. Hoping to determine which software would give his aging desktop replacement the longest battery life, Ciprian Adrian Rusen put IE9, IE10, Chrome 18, Firefox 11 and Opera 11.62 to the test, and both of Microsoft’s offerings had a clear edge on competitors.
All the major browsers: Internet Explorer 9, Internet Explorer 10 beta (included in Windows 8 Consumer Preview), Google Chrome 18, Mozilla Firefox 11 and Opera 11.62. No addons were installed. The machine in question is a two and a half year old HP Pavilion dv7 2185dx with a 2GHz Core 2 Quad Q9000, a Radeon HD 4650 and 6GB of DDR2 RAM. It was configured to run on a power saver profile. The tests were made on a clean Windows 7 installation, with all Windows Updates installed and no other software than the browsers being tested.
Although it was 126% faster than IE10, Chrome 18 only offered 85 minutes of run time. By comparison, IE10 provided 21% more life at 108 minutes, longer than any other browser tested. This could be a testament to the power savings touted by Windows 8. IE9 followed in second place which lasted 104 minutes, while Opera 11.62 ran for 100 minutes and Firefox 11 lasted 92 minutes.
If you look at the average performance score, the winner is Google Chrome, by a huge margin (132% better) when compared to Internet Explorer 9. However, you get the worst possible battery lifetime out of all browsers (18% lower). It seems that Google Chrome doesn’t take advantage of the power saving features included with Windows 7 and maxes out all the resource available.
However, if you want a mix between browsing performance and battery lifetime, your best choice is Opera. Opera was always close to Internet Explorer 9 in terms of battery lifetime (only 4% lower) while delivering browsing performance that’s 83% better.
If I were to pick the winners, they would be Internet Explorer and Opera. Depending on what matters most to you, they are your best choice while browsing the web in battery mode.
