A recent Anandtech study suggests that the web browser has an impact on a mobile PCs battery usage. The test, which analyzed battery performance under various popular web browsers and three websites, can probably not be seen as representative but it could indicate which web browser uses less battery power to operate. A test with more websites would certainly help to get a global result. Still, test results were somewhat surprisingly as the difference between the best and worst performing web browser were greater than two hours.
The web browsers of the test were: Internet Explorer 8, Firefox 3.5.2 with and without adblock add-on, Google Chrome 2, Opera 9.64, 10.0b3 and Safari 4. Three laptops were used in the test. Two entry level Gateway laptops with AMD and Intel cpus and the ASUS Eee PC 1005HA netbook.

Microsoft’s Internet Explorer 8 is the web browser that drains the least amount of battery on the two entry level laptops. Most other web browsers with the exception of Safari come close to that results, especially Firefox with the adblock add-on. The benefit of the adblock add-on suggests that web advertisement does have an impact on battery usage. Safari 4 is the only web browser in the test that performed worst in all three tests.
Google Chrome 2 was first in the netbook test with all other web browsers close by except for Safari which completely drained the battery of the netbook more than two hours earlier than the other web browsers.
Even if the test needs to be replicated with a larger website sample size it seems to indicate that laptop users are better off without the Safari web browser. Internet Explorer 8, Mozilla Firefox with adblock and Google Chrome were the best performing web browsers in the test.
