Hardware performance aside, we ran an HTML5 test to see how much coverage Firefox OS has over new web technologies. It was slightly behind the Motorola Moto E, another low-ender powered by dual Cortex-A7, but it beat the Nokia Lumia 630 hands down.

The Open C performed fairly well in Kraken 1.1, a JavaScript benchmark. Those will run on an even less capable hardware - the bottom is set at an 800MHz processor and 256MB RAM.Īnyway, the Sony Xperia E1 and Nokia X2 are powered by the same chipset and represent the kind of phone the ZTE Open C aim to replace. As we mentioned in the intro, Mozilla wants smartphones as cheap as $25 to ensure everyone can afford one. The Open C represents sort of the Firefox mid-range. The chipset itself is nothing much, two Cortex-A7 cores at 1.2GHz and Adreno 302 with as little as 512MB RAM. That isn't to say they are slow - the ZTE Open C we used for this review is based on Qualcomm MSM8210 Snapdragon 200, which managed to move the UI with acceptable fluidity. Firefox OS is still a very new platform so cross-platform benchmarking will be difficult so we'll stick to browser benchmarks.Īfter all, Firefox OS apps are based on web technologies. Performance is determined by two things - the hardware (obviously) and the software environment.
