We test every phone in real-world scenarios, focusing on its features, design, performance, cameras, battery life and overall value. We document our findings in an initial review that is periodically updated when there are new software updates, or to compare it against new phones from competitors such as Apple, Samsung, Google and OnePlus.

Photography
Photography is a major focus for most phones these days, so we take pictures and videos of various subjects in a variety of settings and lighting scenarios. We try out any new camera modes, such as ProRes Log video with genlock that debuted with the iPhone 17 Pro and 17 Pro Max, or the Gemini-powered Camera Coach tool that launched with the Google Pixel 10 series.
Battery life
Battery testing is conducted in a variety of ways. We assess how long a phone lasts during a typical day of use and note how it performs during more focused sessions of video calls, media streaming and gaming. We also conduct a video playback test as a simple, replicable measure of pure battery life, which isn’t always included in the initial review but sometimes added later in an update.
We test phone features all around the world.
Performance measuring
We use benchmarking apps to measure each phone’s performance alongside our own anecdotal experiences using the phone for our review. Most notable are how the graphics and animations look. Are they smooth? Or do they lag or stutter? We also look at how quickly the phone switches between horizontal and vertical orientations, and how fast the camera app opens and is ready to take a photo.
We perform processor-heavy tasks such as editing photos, exporting videos and playing games. We evaluate whether a newer version of a particular phone includes enough features to make it worth upgrading from older models.
