Recently, MacRumors has received details on the battery currently being tested on the upcoming fourth-generation iPhone SE, and the information corroborates previous findings in relation to the device.

The iPhone SE 4, known by its device identifier D59, is expected to use the exact same battery found in the base model iPhone 14. Partially assembled prototypes of the next iPhone SE have been seen equipped with lithium-ion batteries bearing the model number A2863, which Apple has already used in the past. Internal design documentation also corroborates this change. The battery itself features an improved capacity compared to the current iPhone SE 3:

  • iPhone SE 3: 2018 mAh
  • iPhone 14 (A2863): 3279 mAh

Compared to the battery used in the third-generation iPhone SE, the A2863 battery brings with it an increase of over 1250 mAh, potentially resulting in longer battery life for the end-user.

As with most of the iPhone SE 4, Apple has chosen the A2863 battery as a carry-over from the iPhone 14. While Apple has allegedly developed entirely new batteries for the iPhone 16 Pro with enhanced thermal capabilities, the fourth-generation iPhone SE will continue to use existing parts as a cost-cutting measure.

Developing new components for the iPhone SE 4 would incur additional research and development costs for Apple, so the use of an existing battery would help maintain the relative affordability of the device compared to other iPhone models Apple offers. This also lines up with Apple's previous decisions in regard to the iPhone SE, as the second-generation iPhone SE used the exact same battery as the older iPhone 8.

In terms of other relevant upgrades, the fourth-generation iPhone SE will feature a new iPhone 14-based design, and will be equipped with an Action button and USB-C port, which we've covered extensively in our previous reports.

It is important to remember, though, that the information provided here is pre-production information. While prototype units of the iPhone SE 4 use the A2863 battery, Apple's plans could change as the device is still far from release.

so it would be the same (mostly) size of the iPhone 14, the more important question - will it be the pilot phone for apple's in-house modem chip? maybe the reason for such a larger battery?

The iPhone (not so) Special Edition. I don’t know why they think they need a cheap phone the same size as their other cheap phones (13 & 14). Add in the action button and it makes less sense. Now they’re pulling customers away from those cheap phones to the cheapest one. The SE started as a small phone and should stay that way.

If it's released this 2024 spring, its must be all but finalized production-wise by now.

I wonder what they will do with the lineup after they release this device. How are they going to have 4 6.1” iPhones that all look basically the same? There would be little reason to get a 13 or 14 when the SE exists at a lower price point with a faster chip and USB-C. The only downside is one camera.

The SE didn’t start as a small phone. It started as a phone using an old design which just so happened to be small. If it was meant to be a small phone then they would use the Mini body. Obviously they’re using the 6.1 as it will sell better.

I wonder when they will change their iPhone naming again... when it gets to iPhone 16, 17, 18... 25

They should just call it iPhone (2024), iPhone Pro (2024), iPhone SE (2024)

At this point the numbers and iterations become more and more irrelevant, and it looks messy. A marketing hot mess. Where is the logic, when you get to iPhone 99... it just sounds increasingly stupid.

Not being a huge camera user I think this might make a really nice device for those of us that use our phones as communication devices primarily.

if they use 48mp sensor I wouldn’t even call it a downside, if there’s a choice between having a dual-camera system with a 12mp main sensor or having a single camera with 48mp sensor I’d personally choose the latter.

I keep thinking this about the SE rumors. A XR-based SE makes sense. As does a Mini. But a 14? the 12-15 is hard enough to tell a difference. 12-16 and SE will be identical.
