While Apple's product pages for the new iPhones don't make mention of upgraded batteries it turns out that they are actually there. Although you're unlikely to notice any difference in how long those batteries actually last.
In fact, the difference between the old and new batteries is so marginal, that it's perhaps understandable Apple kept it to itself.
That regulatory database confirms that the new iPhones do indeed have bigger batteries than their older counterparts, although the difference is very small indeed.
Here's what iPhone 15 and iPhone 15 Pro buyers are getting under the hood.
- iPhone 15 Pro Max — 4,422 mAh
- iPhone 15 Pro — 3,274 mAh
- iPhone 15 Plus — 4,384 mAh
- iPhone 15 — 3,349 mAh
That doesn't mean all that much in isolation, we'll admit. So let's take a look at what batteries Apple used in the iPhone 14 and iPhone 14 Pro devices as well.
- iPhone 14 Pro Max — 4,323 mAh
- iPhone 14 Pro — 3,200 mAh
- iPhone 14 Plus — 4,325 mAh
- iPhone 14 — 3,279 mAh
While those differences aren't all that big. they're obviously welcome.
The biggest question some will have is whether these new batteries will stay healthy for longer. Many people with iPhone 14 and iPhone 14 Pro models reported their battery health was particularly bad after less than a year of ownership.
