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.
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. Here is where we also test for screen glare in our sunlight legibility test.
Our speakerphone loudness test is perhaps the simplest and most straightforward of them all. Here, we measure how loud the speaker of a given device is. Keep in mind that we measures pure loudness, and not the clarity of the sound.
This test basically rates how well your device performs as a music player. We record audio samples from the tested device and we run them through some audio analysis software to examine the audio output.
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.
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 activites.
While testing the audio through the headphone jack, it would be very informative to take the Vrms measurements to indicate the drive capabilities of the output amp for high impedance headphones. Also the output impedance of the amplifier would be hig...
Sorry late to the party. Not sure if this question has been asked. When you test loudspeakers, you take measurements with the handset loudspeaker facing the loudness meter at a distance of exactly 1m. What happens if you have a bottom firing speaker ...
