Don’t expect a battery boost on the Samsung Galaxy Z Fold 4

New leaks surrounding the Samsung Galaxy Z Fold 4 appear with increasing regularity as the foldable phone’s expected August launch window approaches, and the latest concerns one of the most important specs of all: the capacity of the battery.

The GalaxyClub team has spotted two phone batteries that Samsung has registered with regulators in South Korea, and all signs suggest these batteries will be heading to the Galaxy Z Fold 3 successor.

We have nominal capacities of 2002 mAh and 2268 mAh, making a grand total of 4270 mAh. That’s nearly identical to the 2,275mAh capacity of the Galaxy Z Fold 3, and like its predecessor, the Galaxy Z Fold 4 will likely be marketed as having a 4,400mAh battery (phone makers are promoting what we calls the “typical” capacity, which is greater than the rated capacity).

Do the math

Just a few days ago we heard rumors that the Galaxy Z Fold 4 would be thinner and lighter than the Galaxy Z Fold 3 – and keeping the same battery capacity this year will certainly help ensure that the next foldable is more compact. .

There has also been talk of a drop in price for Samsung’s flagship phone, which a lower battery capacity may contribute to. For reference, the Galaxy Z Fold 3 launched with a starting price of $1,799 / £1,599 / AU$2,499.

A more affordable foldable would certainly be welcomed by consumers – and so while it may be disappointing that the Samsung Galaxy Z Fold 4 doesn’t get a battery capacity upgrade, it’s likely we’ll see the resulting benefits in other areas.

Analysis: battery capacity assessment

As always with battery capacities, it’s important to wait until you can test the phone before making a full judgment – although the mAh (milliamps per hour) number is a useful shorthand for estimating battery life. battery on a smartphone or tablet.

Hardware and software optimizations mean that phone makers are often able to optimize battery life from the same battery capacity. Apple, which of course has full control over the iPhones it makes and the iOS software running on them, is particularly good at this.

When we reviewed the Samsung Galaxy Z Fold 3, we found that the foldable phone generally lasted all day on a single charge. It’s likely that Samsung will target the same all-day battery life when it releases the Galaxy Z Fold 4.

So while it looks like battery life isn’t one of the main selling points of the upcoming Samsung foldable, we’ll have to wait for our review to see exactly how long you can expect between charges. As always, this will depend on how the phone is used, as well as settings such as screen brightness.
