Samsung equipped the Galaxy Z Fold 4 with a very similar capacity battery to its predecessor, but also introduced its latest 12th generation OLED display technology with brighter and more efficient 1-120Hz panel, as well as the 4nm Snapdragon 8+ Gen 1 chipset.

This made us hopeful that we can expect the Z Fold 4 to outlast the Z Fold 3 and last more than the average seven hours of screen-on time while browsing or watching video and a bit less for playing games, as our thorough Z Fold 3 review's various battery tests suggest.

Samsung Galaxy Z Fold 4 battery size

4400 mAh

Coming in with a 4400mAh battery, split in two cells, the Z Fold 4 comes with a similar battery capacity to its predecessor. Interestingly, the Z Flip 4 adopted a new, more minimal hinge design, which opened up space for a slightly larger battery than the Z Flip 3 (3,700 mAh vs 3,300 mAh), and while it was heavily implied that the Z Fold 4 has scored a similar more compact mechanism, the new space was probably not enough to accommodate a larger battery.

However, the more probable and logical assumptions is that it was occupied by another equally important component, such as the upgraded camera unit, taken directly from the Galaxy S22.

Samsung Galaxy Z Fold 4 battery life and charging speeds

The 4,400mAh battery of the Samsung Galaxy Z Fold 4 is of average size for today's flagship phone standards that are banging on the 5000 mAh threshold. With such a battery and the combination of a more efficient 1-120Hz refresh screen and an effective Snapdragon 8+ Gen 1 chipset, we were hopeful that the Z Fold 4 will have a much better battery life than its predecessor.

With the same battery size, the Z Fold 4 predecessor lasted 8 hours and 15 minutes of screen-on time in our browsing test with the high refresh rate turned on and a bit shorter endurance of 7 hours when streaming YouTube videos. The Galaxy Z Fold 4 boosts those endurance numbers by over 50% and 30%, respectively, which is a jaw-dropping development.

Gaming on the big Z Fold 4 display is actually a rather frugal activity with more than 8 hours of screen-on time, but when you turn on the 120Hz mode, the battery life goes down to less than 5 hours since the more powerful Snapdragon 8+ Gen 1 generates more heat under pressure, so this section of the battery test actually went slightly in favor of the Fold 3.

Still, the Galaxy Z Fold 4 battery life is a revolutionary change from what the Z Fold 3 commanded and you can use the new Light performance mode of Samsung to eke out even longer battery endurance from the Z Fold 4. We tested the light mode on the Z Fold 4, but, at least on our Wi-fi browsing battery test, it didn't make much of a difference, and you can't use it for gaming, too.

The new Light performance mode of Samsung would prolong the excellent for the cell capacity Z Fold 4 battery life even further

As for the Galaxy Z Fold 4 charging speeds, they cap out at 25W which means it will take about an hour and 20 minutes to bring the Z Fold 4's battery to a full charge, according to our testing.
