GalaxyClub has discovered that Samsung has registered two phone batteries with South Korean authorities, and all the indicators point to the batteries being used in the sequel to the Galaxy Z Fold 3.
We have rated capacities of 2,002mAh and 2,268mAh, for a total of 4,270mAh in our arsenal of batteries. While the Galaxy Z Fold 4’s battery capacity is practically equal to that of the Galaxy Z Fold 3, it’s probable that Samsung will sell it as having an even larger capacity—the so-called “typical” battery capacity—than the certified capacity.
Doing the math
Galaxy Z Fold 4 is expected to be slimmer and lighter than Galaxy Z Fold 3, according to recent speculations. Keeping battery capacity constant will also assist to make this year’s foldable more portable.
Low battery capacity may lead to a decrease in the flagship Samsung phone’s pricing as well, according to rumours. For comparison, the Galaxy Z Fold 3 went on sale for $1,799 / £1,599 / AU$2,499 when it was first released.
The Samsung Galaxy Z Fold 4’s lack of a battery capacity improvement may surprise some users, but it’s likely that the device will gain in other ways as a consequence of the lack of a more cheap foldable.
Reviewing the battery’s energy storage capacity
The mAh (milliamperes per hour) value is a good shorthand for calculating battery life on a smartphone or tablet, but it’s vital to wait until we can really try the phone out before reaching a final assessment.
There are several ways to improve the battery life of a smartphone, including hardware and software modifications. Even though it has complete control over its own iPhones as well as its own iOS operating system, Apple excels in this area.
On a single charge, we were able to go through a whole day using the Samsung Galaxy Z Fold 3. The Galaxy Z Fold 4 is anticipated to have the same all-day battery life as Samsung’s current flagship, the Galaxy S7 Edge.
Since battery life isn’t a major selling feature for the next generation foldable, we have to wait until our review before finding out just how long you can go between recharges. Depending on how the phone is used and the brightness of the display, this may or may not be the case.
