The Galaxy Z Fold4 and Flip4 could be said to be Samsung's most cutting-edge flagship smartphones to date, thanks to their updated flexible main displays. However, they still have smaller batteries than their closest 'normal' counterpart the Galaxy S22 Ultra. Nevertheless, the 3 devices seemed to be capable of some extremely surprising results when put to a test of screen-on time.

Samsung touts its Galaxy Z Fold4 and Galaxy Z Flip4 as its most advanced foldable devices yet; however, the OEM has not managed to upgrade their battery capacities much, at 4,400mAh and 3,700mAh respectively.

At 5,000mAh, the Galaxy S22 Ultra faces no such limitations by comparison. Therefore, one might presume that the older, good old candy-bar-form flagship would have the edge in terms of day-to-day endurance. However, according to a new video by TechDroider, one might just be wrong about that.

The YouTuber pitted the 3 top-end devices against each other, as well as the OnePlus 10 Pro and Xiaomi 12S Ultra as Snapdragon 8 Gen 1 and 8+ Gen 1 comparators for the Z Fold4/Flip4 and S22 Ultra respectively.

Once those subjects had been joined by an iPhone 13 Pro Max, presumably as a battery benchmark, the test was underway. The protocol consisted of constant screen/processor engagement via extended runs of games like PUBG, video apps like Instagram and general camera app use until the devices eventually ran down to zero.

It yielded a number of unexpected results, not the least of which was the Galaxy S22 Ultra powering down first at 8 hours and 56 minutes of this treatment.

Furthermore, the Galazy Z Flip4, despite lagging behind at regular check-points, was depicted as beating it (albeit by a narrow margin of 8 minutes). The Galaxy Z Fold4 was next to go at 9 hours 18 minutes.

The 10 Pro was the first non-Samsung device to tap out (despite being the only other 5,000mAh smartphone), followed by the 12S Ultra, leaving the 13 Pro Max to an almost inevitable victory by enduring from 0 to 100% for 10 hours and 35 minutes.

Therefore, it seems the S22 Ultra failed in this challenge. It was, moreover, also reported as the hottest device at the end of the test, leading to speculation that its 8 Gen 1 processor (also made by Samsung) was the defining factor here.

The Z Fold4 and Flip4 were recorded as among the coolest, along with the iPhone 13 Pro Max - then again, it should be noted that they were of course virtually out-of-the box devices.

On that note, TechDroider claims to have standardized variables such as brightness, refresh rate and resolution as much as possible between the 6 participants, although these efforts are not documented on screen.

Accordingly, while battery test videos like this might be entertaining and spark debate, they can hardly be leveraged as conclusive scientific proof that a given device has bad battery life. For example, it would be nice to see one in which the tests are repeated even once for validation purposes.
