We test each phone in real-world scenarios and focus on its features, design, performance, camera, battery life and overall value. We document our findings in our initial review and update regularly when new software updates are available, or we compare them to new phones from competitors like Apple, Samsung, Google, and OnePlus.
The camera hardware of Galaxy Z Flip 5 is basically the same as that of Z Flip 4.
photography
Photography is the main focus of most phones these days, so we capture photos and videos of a variety of subjects in a variety of settings and lighting scenarios. We tried all the new camera modes, like the Action mode introduced with the iPhone 14 series, or the Unblur photo tool introduced with the Google Pixel 7 series.
Battery Life
Battery testing can be performed in a variety of ways. We evaluate the phone’s battery life during daily use and record its performance during more intensive sessions such as video calls, media streaming and gaming. We also ran a video playback test as a simple, reproducible measure of pure battery life, which isn’t always included in initial reviews but is sometimes added in updates.
performance measurement
We use benchmarking apps to measure each phone’s performance, combined with our own anecdotal experience using the phones for review. Of note is the look of the graphics and animations. Are they smooth? Or do they have lag or stutter? We also looked at how quickly the phone switched between horizontal and vertical orientations, and how quickly the camera app opened and was ready to take a picture.
Emergency SOS may be one of the most important features launched on any phone this year.
We perform processor-intensive tasks such as editing photos, exporting videos, and playing games. We evaluate whether new versions of specific phones include enough features to make them worth upgrading from older models.
