Benchmark Suite, Methodology, And Test System Specs
Comparing smartphone performance is a little more challenging than comparing PC components, since we have to find benchmarks that work across Windows Phone 8, Android, and iOS. Of the three, Windows Phone 8 has the lowest number of cross-platform testing apps, which makes sense when you consider its marketshare. Not only that, but particular phone models are sometimes incompatible with specific metrics, throwing yet another wrench in the pipe.

Further complicating today's performance analysis, we test all of our smartphones at a calibrated 200 nits of screen brightness to ensure comparable battery life and display measurements. Unfortunately, Windows Phone 8 does not have an adjustable screen brightness slider; it is limited to three factory preset settings: low, medium, and high. To provide comparable battery life and display measurements, we had to test at those three brightness levels and use them to extrapolate a 200 nit calibrated result. It's not ideal, but it's the best possible method we have at our disposal.
Test System Specs
Despite these challenges, Tom's Hardware is all about objective measurements and we've done our absolute best to provide the most cross-platform tests for as many platforms and SoCs as possible.
