GSMArena feature labs: The tests

Introduction

The GSMArena Labs are tests designed to give an objective account of how a device performs in real-world scenarios. In short, it's about what you can expect from a gadget you're planning to buy. Our tests are constantly being developed and refined to keep up with the latest emerging technology. We aim to give you real results, avoiding convoluted technical jargon, so you can easily compare all tested devices.

We are offering a detailed look into the specifics behind out testing process, including what we test, why we test it, and how we go about the whole thing. While it provides enough technical information should you require it, we've tried to cover each subject in a way so as not to confuse the inexperienced reader, and the following pages a great place to get introduced to any of these topics.

In brief, here is an overview of our various testing routines. Clicking on any of the tests below will take you to its respective page, where more detailed information can be found.

• 

  Display

  Our Display test should help you get an idea of the luminosity generated by each tested display and the ratio between the brightest white and darkest black it can show.

• 

  Speaker test

  Our speaker loudness test was reimagined from the ground up in 2020. It allows you to listen to recordings of how the phone speakers sound, compare their loudness and frequency response.

• 

  Photo/Video Compare

  Our photo and video compare tools are designed to measure the performance of cameraphones. Both video and still images are taken under identical, controlled conditions in our studio, so you can easily see how different phones and tablets stack up.

• 

  Battery life

  Our final test measures the battery of a given device while performing the various tasks you would typically put it through. We measure talk time, browsing and video playback, then provide a general endurance rating based upon all three activities.
