The Flip 3 ran for 9 hours and 30 minutes even with the low-power mode period. So what we're seeing is that the Flip 4 has noticeably better screen-on time. The Fold 4 got a total of 11 hours, 30 minutes of video playback on the main inner screen, with a significantly shorter period of low-power mode toward the end.

The Z Flip is the first foldable smartphone to use a glass display, while previous foldable phones such as the Motorola Razr and the Galaxy Fold have used plastic displays. Using a glass display results in a more durable screen, and reduces the screen crease in the folding point.

Samsung says all Watch 4 models can last up to 40 hours on a charge. Our reviews found that the smaller versions don't quite make it there. The larger 44- and 46-millimeter models last longer between top-ups, more closely matching Samsung's predictions.

In our testing, the Galaxy Z Flip5 was good for a little over 15 hours of video playback and 12 hours of Wi-Fi web browsing - not amazing, not half bad either. The nearly 28 hours on a voice call are about the norm for a clamshell.
