Internet Explorer provides best browser battery life in recent test

A series of tests with four major browsers concluded that Internet Explorer versions 10 and 9 provide the longest battery life compared to competitors, while Google Chrome finished in last place with a battery life performance more than 20% poorer than the leader.

The tests were conducted by Ciprian Adrian Rusen of 7tutorials, who used a two-and-a-half year old HP Pavilion dv7 2185dx laptop for the test. The laptop was equipped with an Intel Core2 Quad Q9000 at 2.00 GHz, 6 GB of DDR2 RAM and an ATI Mobility Radeon HD 4650. Due to the age of the laptop, Rusen was already experiencing less than optimal battery life when using his laptop, which is what spurred the tests, as he was keen to find the browser that provided him the longest battery life.

The tests pitted Internet Explorer 9, Internet Explorer 10 beta (which is included in the Windows 8 Consumer Preview), Google Chrome 18, Mozilla Firefox 11 and Opera 11.62 all against each other, with no add-ons installed on any browser. A clean Windows 7 installation was used (except in the case of Internet Explorer 10, since it's only available in Windows 8), with the most recent Windows Updates installed. The Peacekeeper battery test was used for the benchmark. Rusen ran each test three times to get an average of results for each browser.

Rusen notes that the browser that gave him the most trouble was Google Chrome, which Rusen says crashed on him until he reinstalled the browser. Even after reinstalling, Chrome failed to record results in Peacekeeper for reasons unknown to Rusen, among other issues.

The averaged results of Rusen's tests can be seen below.

While Chrome outscored all its competitors when it came to Peacekeeper's performance score, its battery life was significantly lower than other browsers. Rusen's conclusion is that Internet Explorer 9 or 10 is the best bet when battery life is the top consideration, and that Opera is the best choice for a mix of browsing performance and battery life.

It should be like this, Internet Explorer is already an inner part of the OS, that's why it also has a very low memory ram usage....

Reasonable results and that seems to be inline with what I noticed on my laptop. I'll stick with Opera while on battery. While plugged in, Chrome serves me well.

So they tested all browsers on Windows 7 and IE10 an 9 on Windows 8??

No only IE10 on Windows 8. IE9 still beats out the other browsers on Windows 7 though.

Adblock Plus + NoScript = Firefox Winner!

Ignoring these is like ignoring a core Firefox feature.

Besides, we all know a lot of IE components get loaded with Windows. That's why it starts faster on Windows.

Nothing you've mentioned has any impact on the results of the above "test/benchmark".
(Unless you block the peacekeeper scrips, then you might just as well open an about:blank page and claim superiority)

Would have been nice to have seen Safari in the comparison too to see how that compares - it is a "major" browser after all, and more popular than Opera!

how the hell did they correlate a browser to battery life is beyond me. i am however curious to know if it will improve my sex life.

A research showed that a Wifi signal can reduce the amount of sperm you produce. So how longer your mobile/tablet stays on and you keep it near your crotch, how less sperm you make. So for improved sex life should you use Chrome since then your device dies faster and the Wifi signal is then gone.

But then you would have more sperm increasing the risk of pregnancy. That leads to 9 months of no sex life. More wifis = more sex.

You think pregnanacy leads to ONLY 9 months of no sex?

Hate to have this experience.
I had sex all the way through my wife's pregnancy, minus the 6-8 weeks recovery time after labour.

Turn off gpu accell.. When u run off battery to decrease the amt of stress on gpu if you got hybrid discreet and embedded. If you have it setup for gpu accel the discreet kicks in more than the embbedded. This is the reason aero also kicks of on battery as well. Did they consider any of thos?

IE9, 10, and FF11 all have hardware acceleration on too.

With hardware acceleration off, your GPU it will be drawing power, its just underclocked to 2D levels. If GPU acceleration is on, I highly doubt it will cause the GPU to increase its clockrates to that of 3D so the power draw shouldn't be too much different (still worth a test though!).

Also, with some of the processing power offloaded to your GPU the CPU won't be taxed as much and speedstepping would kick in and underclock the chip saving you power.

Not sure why browser hardware acceleration is causing nvidia optimus to switch to the discrete chip though, pretty dam sure embedded chips are good enough to handle that by themselves.

One of the main reasons behind hardware acceleration is so the GPU can take over processing the CPU is inefficient at. In other words, hardware acceleration is more efficient and better for power draw.

So what you are saying is, in real use scenario, when I switch to battery, I need to go into some setting (device driver or browser setting) and manually change settings. Then when I switch back to wired, I need to mess with those settings again, all to make sure that a browser doesn't waste my battery - which, as others above have commented, would not help. Or, rather than changing a bunch of settings when i switch between wired and wireless, i could just use a browser that saves battery without changing settings.

I knew that but I didn't think that the effect would work that way that razor said above... Some people have complained about that issue not happening as expected and that's why I said what I did.

No. It's as simple as just enabling hardware acceleration in your browser, and leave it at that setting, regardless whether you're using battery or plugged in.
