According to MacRumors, the media recently received detailed information about the battery currently being tested for the upcoming fourth-generation iPhone SE, which confirms previous findings related to the device.
The iPhone SE 4 has a device identifier of D59 and is expected to use the exact same battery as the standard iPhone 14. Partially assembled prototypes of the new phone are already equipped with a lithium-ion battery model A2863, which Apple has used in the iPhone 14 in the past. Internal design documents also confirm the change.
Compared to the current iPhone SE 3, the capacity of the iPhone SE 4 battery itself will be increased:
iPhone SE 3: 2018 mAh
iPhone 14 (A2863): 3279 mAhThe A2863 battery has an increased capacity of 1,250 mAh compared to the battery used in the third-generation iPhone SE, which should extend the battery life of the new phone.
Apple is said to have developed a new battery with stronger heat dissipation capabilities for the iPhone 16 Pro, while the fourth-generation iPhone SE will continue to use existing parts to reduce costs. Developing new parts for the iPhone SE 4 would incur additional R&D costs for Apple, so using existing batteries would help keep the device affordable relative to other iPhone models.
In terms of other related upgrades, the fourth-generation iPhone SE will adopt a new design based on the iPhone 14 and will be equipped with an Action button and a USB-C interface.
The information provided here is before trial production. Although the iPhone SE 4 prototype uses A2863 batteries, Apple’s plans may change as the device is still far away from launch.
