All of us know how challenging it can be to squeeze more and more amount of battery juice when working on laptop running on battery power. Hence it becomes necessary to know what factors matter the most to use all that battery power in an efficient manner especially for those of you who own an old laptop with an ageing battery.
What softwares you use matters alot and if you are working on the internet then choosing the browser with the best economy of battery usage can make a huge difference. But which browser is the most economical when it comes to power consumption?
Well we have got quite a conclusive answer to that question with some surprising results from the benchmark tests that were used to analyse the performance of some of the most popular web browsers in terms of power consumption. The browsers included in this list are Internet Explorer 9, Internet Explorer 10 beta (included in Windows 8 Consumer Preview), Google Chrome 18, Mozilla Firefox 11 and Opera 11.62 without any add-ons installed.
The tests were run using an HP Pavillion dV7 2185dx having the following hardware configuration: Intel Core2 Quad CPU Q9000 @ 2.00 GHz, 6 GB of RAM DDR2, ATI Mobility Radeon HD 4650.
On the software side a clean installation of windows 7 was used with the power saver plan being used with tweaked settings to keep the hard disks running and preventing the laptop from going into sleep until it reaches a critical battery level.
No other softwares except the browsers were installed on the system.
For testing the Internet Explorer 10 beta a clean installation of windows 8 consumer preview was used on the same laptop with similar settings to those of windows 7 were used.
Peacekeeper battery test was used as a benchmark that keeps testing the browser until the battery runs out and the system is put to sleep. Multiple number of tests were carried out and an average of three successful runs was used in the final verdict because there were many test runs that were incomplete due to various reasons such as browser crash, loss of internet connectivity, loss of test results etc.
Coming to the results, they aren’t even close to what anyone would predict. Google chrome came out as the most troublesome browser with inconsistent results and a number of crashes that were resolved by re-installing it. Chrome performed very badly with instances of unknown behaviour.
On the other hand surprisingly enough Internet Explorer 10 came out with most constant results. The time difference in its worst and best performance was of only 4 minutes where as the least consistent Firefox had the worst and best time difference of 21 minutes. It was pretty odd to find out all of the browsers worked very well without any major issues during these tests except the Chrome which showed quite alot of instability.
Below is a table of the results that clearly lists out Internet Explorer 9 on Windows 7 as the best browser to be used when running the laptop on battery power. But looking at the performance scores, it is quite clear that Google Chrome has left all of the others way behind with a margin of 132% when compared to internet explorer 9. So, it gives best performance but does not exploit the power saving features of windows 7, maxing out on all available resources.
Therefore, the browser that gives the best mix of performance and battery timing is Opera. It performed very close to IE in terms of batter lifetime with only a mere difference of 4% while providing 83% better browsing performance.
So if you want to pick out a winning browser out of all these we can say for sure that IE and Opera are the only choices but then again it all depends on your needs and priorities, so do let us know in the comments which one would you use and how was your experience?
