This year, Apple will be doing a lot of “firsts”.
The company will be scoring a new CEO for the first time in more than a decade. Apple will also be releasing its first foldable iPhone. Finally, we aren’t going to receive a regular iPhone this year as Apple will push its release back to early 2027.
That’s quite a lot of firsts, but regardless, we are still getting a number of new iPhones this fall.
Aside from the foldable iPhone 18 Ultra, we are also going to see the iPhone 18 Pro and iPhone 18 Pro Max flagship models. Currently, a number of upgrades is rumored for the two devices, including an Apple A20 Pro chipset, a camera with variable aperture, a bold new red color, and finally, potentially larger batteries on both models.
Here’s everything we know about the larger batteries likely making it to the upcoming iPhone models.
iPhone Ultra
Apple’s first foldable phone will most certainly make use of a dual-cell battery, with each one positioned in either half of the device. This split design would allow a larger total capacity to be used, which is something you can’t really do with a standard rigid battery.
And the rumor mill agrees that the iPhone Ultra will easily pack the largest battery on an iPhone so far, with estimates varying between 5,400 and 5,800 mAh, which would easily place the foldable in the upper echelons of battery prowess. Sure, it’s not in silicon-carbon territory just yet, but iPhones are getting close to there, surely.
Current rival devices boast smaller batteries: 4,400 mAh on the Galaxy Z Fold 7 and 5,015 mAh inside the Pixel 10 Pro Fold. Their successor probably wouldn’t be equipped with much larger batteries either, so the iPhone has the potential to be among the foldable phones with the largest battery in the US. Only the Motorola Razr Fold could stand higher with its 6,000 mAh battery.
However, Apple might have a leg up in terms of battery life thanks to its upcoming Apple A20…
