Rendering and Computational Performance
Smartphones are far from super computer capabilities, and web browsing can be quite taxing on the hardware, especially with highly complex and dynamic web pages. Because smartphones are much more limiting in screen space, functionality, and even network speeds, you can’t exactly flip through pages like would might on a desktop machine. It’s extremely important that a browser is able to download and render a page quickly.
In the Page Loading tests, we time how long it took each browser to completely load a web page. We did this on both a Wi-Fi network (averaging 25.6Mbps), and mobile data network (averaging 4.15Mbps). Too ensure fairness, we tested over a wide variety of pages, ranging in complexity. We timed each page many, many times.
