It makes a difference

Ars Technica reported this week that they tested the developer preview of Android L and saw a whopping 36 percent improvement in battery life! Google made improving battery life a priority, and it sounds like they are succeeding. I can’t wait to test Android L with BatteryXPRT.

This is a spectacular example of how a change in software can change benchmark results, but it’s hardly unique. I’ve written before about how background activity on a phone depressed my friend’s WebXPRT scores. AnandTech used both IE 11 and Chrome 30 to test the Surface Pro 2 with a variety of benchmarks, including WebXPRT, SunSpider, Octane, Browsermark, and others. Browser choice had a noticeable impact on results – about a 40 percent difference for WebXPRT and a 76 percent difference for SunSpider!

People are generally pretty aware that changing the hardware changes performance. However, sometimes they lose track of software differences. When you compare scores, it’s not always possible to keep all the variables the same, but it’s crucial to know what the differences are.

In other BenchmarkXPRT news, we’re making some final adjustments to HDXPRT 2014, and the general release is just around the corner.
