Window weblog 7Tutorials has done another round of their web browser battery usage tests, and the results are pretty much the same as usual: Internet Explorer keeps your computer running longer.
Which version of Internet Explorer (Touch or Desktop) depends on your hardware, but on each machine, Internet Explorer came out ahead. In some cases, by a pretty big margin—for example, Chrome lasted nearly two hours shorter on a Toshiba tablet, and about an hour shorter on the Surface Pro 2.
Of course, that doesn’t mean you should always use Internet Explorer, but if you’re somewhere without an outlet, it may be worth a temporary switch. Check out 7Tutorial’s most recent round of tests at the link below.
