Samsung Galaxy Z Flip 4 and Fold 4 Battery Life: One Is a Clear Winner
The Samsung Galaxy Z Flip 3's biggest drawback was battery life. While the Z Flip 3's price, style, and form factor attracted plenty of buyers, those buyers sacrificed screen-on time for a fashionable form facvtor.
Good news is here: Our first battery tests show the Samsung Galaxy Z Flip 4 as having noticeably better battery life than the Z Flip 3, to the tune of two additional hours, which can really make a difference toward the end of the day.
The Galaxy Z Fold 4, meanwhile, appears to have about the same battery life as the Z Fold 3, which is fine.
Our standard battery test entails running a YouTube video at full screen brightness over a slightly wobbly Wi-Fi connection, with 4G/5G on in the background. It's not quite like real-world use, but it's something we can do that lets us directly compare phones across the years.
The Galaxy Flip 4 ran the video for 9 hours, 25 minutes before hitting 10% battery and entering low-power mode, when it mandatorily reduced screen brightness. It then toddled on for another 2 hours, 7 minutes, for a total of 11 hours and 27 minutes.
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 overall results were similar to the Z Fold 3 (11 hours, 25 minutes), and actually better than the Samsung Galaxy S22+ (10 hours, 30 minutes).
So, a little hesitantly, I can say that the Flip 4's battery seems to be up to par in a way that the Flip 3's wasn't. It still isn't going to be a major battery leader like the Samsung Galaxy S22
