The iPhone SE 4 will get the battery from the iPhone 14 - its capacity is 1,250 mAh more than that of the iPhone SE 3
Previous leaks suggest that the 4th generation iPhone SE will inherit the design of the iPhone 14. Now it turns out that it's not just the design.
Here's What We Know
MacRumors has received information that the iPhone SE 4 is testing a lithium-ion battery with model number A2863. It is the same one used in the iPhone 14. Apparently, using already existing parts, Apple reduces the cost of development and production of a new model of smartphone.
The battery has a capacity of 3279 mAh, and this is a significant increase over the current iPhone SE 3. It has a 2018 mAh battery, which means that the battery of the future novelty will be more than 1,250 mAh larger.
But keep in mind that while iPhone SE 4 prototypes use the A2863 battery, Apple's plans could change as the device is still a long way from release.
