The Samsung Galaxy Z Flip 4 just keeps on sounding better

In the space of a day or two, the Samsung Galaxy Z Flip 4 went from disappointingly sounding to quite exciting, because on the heels of a leak suggesting a serious power upgrade, it now looks like the battery could be better than expected.

MyFixGuide spotted a listing from Chinese certification agency 3C, which suggests that the Samsung Galaxy Z Flip 4 will have two batteries with a combined capacity of 3,595 mAh.

Now that’s already more than the Samsung Galaxy Z Flip 3 – which has a 3,300mAh battery – and than a previous leak suggested, as it pointed to a 3,400mAh battery.

But the battery capacity we see on this list is almost certainly the “nominal capacity”, which is basically the minimum capacity you’ll get from the battery. Samsung (and most device manufacturers) actually advertise ‘typical capacity’, which is the estimated average value of the battery – so a bit higher than the rated capacity.

This is the typical value we mentioned for the Z Flip 3 and for the previous leak, and with a rated capacity of 3,595 mAh, the typical capacity here is likely to be even higher at around 3,700 mAh – a leaky figure @UniverseIce suggests.

So that’s around 400mAh more than the Samsung Galaxy Z Flip 3, which isn’t negligible, especially since the screens look similar and the chipset is likely to be more efficient. So if anything, the Samsung Galaxy Z Flip 4 might be less battery hungry than its predecessor.

We would of course take this claim with a grain of salt, especially since it contradicts an earlier rumor. But certifying agencies like this usually work from official information, so there’s a good chance it’s accurate.

Analysis: A big boost but we want even more

Battery life has long been an issue with smartphones, and it’s even more of an issue with foldable phones, because while they often have larger screens than conventional phones, they also often have smaller batteries.

The Samsung Galaxy Z Flip 4 will likely be in line with a conventional large phone, as leaks point to a 6.7-inch foldable display, but even a 3,700mAh battery would be much smaller than most juice packs. phones of this size.

It’s rare to find a big phone with a battery below 4,500 mAh, and many are 5,000 mAh or more.

But with the hinge, secondary screen and multiple sections needed in a foldable phone, there’s a lot more to it than normal smartphones, which means battery space is more limited – unless you want something really bulky thing. So it’s not an easy problem to solve.

Hopefully, the supposed upgrade here will suffice, but either way, it’s a must, as our Galaxy Z Flip 3 review described its battery as the “biggest downside.”
