Is happening! Well, presumably (!) it’s happening but presumably it’s better than nothing
Apple’s iPhone 15 series is about two months away from the official launch, and it’s now clear that the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max are expected to have significantly larger batteries than the iPhone 14 and iPhone 13, which came with cells of similar size.
- iPhone 15 – 3,877mAh (compared to 3,279mAh on iPhone 14)
- iPhone 15 Pro – 3,650mAh (compared to 3,200mAh for iPhone 14 Pro)
- iPhone 15 Plus – 4,912mAh (compared to 4,325mAh for iPhone 14 Plus)
- iPhone 15 Pro Max – 4,852mAh (compared to 4,323mAh for iPhone 14 Pro Max)
But there’s more! In case you haven’t heard, Apple’s new Pro flagships are also expected to feature the industry’s first 3nm chip built in partnership with Taiwanese semiconductor giant TSMC: the A17 Bionic. The higher efficiency of the innovative A17 chip and the larger batteries in all iPhone 15 models look extremely promising, because Apple’s iPhones are already leaders in all battery charts. Considering their conservative (or downright small) batteries, Apple is going big this time around! Or at least bigger. Could the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max leave the Android competition in the dust by lasting even longer than their predecessors? I say let’s evaluate Apple’s chances for the total battery acquisition right now instead of waiting until September.
Oh, and I also think the supposed increase in battery size could mean some long-awaited updates could be coming to the iPhone. In fact (if they happen), those could make an even bigger difference to your day-to-day use than the bigger cells. Take wildcards with a pinch of salt but they sure do sound sweet
Leaving Android in the dust: iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max battery life could be 20-30% better than iPhone 14

iPhone 15 Plus will have a 5,000mAh battery. Almost. Close enough.
As you can see, according to our battery tests, Apple’s current battery champion, the iPhone 14 Pro Max is almost on par with the Galaxy S23 Ultra when it comes to how long you can surf the web – you get around 19 hours on both. However, the iPhone 14 Pro Max gets 2 hours more battery life when streaming YouTube videos than the Samsung flagship, as well as 1.5 hours more battery life in 3D gaming sessions.
The reason I’m making this comparison is because it’s Apple versus Samsung, but also because the two most popular flagships are also the longest-lasting out there right now (except for some gaming phones with much larger batteries).
As you can see, the iPhone 14 Pro Max is already ahead of the Galaxy S23 Ultra, which leads to the logical question: how much can it improve the iPhone 15 Pro Maxs battery? And of course, what about the rest of the iPhone 15 range?
The improvement in battery life in the iPhone 15 series compared to the iPhone 14 may be greater than expected

iPhone 15 series with 20-30% better battery life than iPhone 14? It’s not impossible.
- iPhone 15 battery is getting 18% bigger compared to that of iPhone 14
- iPhone 15 Plus battery is getting 14% bigger compared to that of iPhone 14 Plus
- The iPhone 15 Pro battery is getting 14% bigger compared to that of iPhone 14 Pro
- iPhone 15 Pro Max battery is getting 12% bigger compared to that of iPhone 14 Pro Max
Simple math would suggest that the iPhone 15 should last 18% longer than the iPhone 14, while the iPhone 15 Plus should last 14% longer than the iPhone 15 Plus, and so on. with the updated chips of iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max.
While it’s difficult to estimate exactly how much more efficient the new A17 Bionic will be than the A16, it’s safe to assume that you can expect at least some efficiency gains when moving from 5nm to 3nm chips. In fact, I’m willing to bet that the dramatic increase in battery size and the move to 3nm could result in 20-30% better battery life across the entire iPhone 15 lineup.
But how did I arrive at that number? Well, Apple’s future can often be predicted by looking at the company’s past. Remember, the iPhone 13 Pro Max had an 18% larger battery than the iPhone 12 Pro Max and although both of Apple’s big flagships were equipped with 5nm chips, the 13 Pro Max had significantly better battery life compared to its predecessor. Our comparison showed an average runtime of 2.5 hours longer on the 13 Pro.
The significantly larger batteries and the big leap in processing efficiency should/could contribute to even bigger gains in overall battery life on the iPhone 15 models compared to previous iPhones and, of course, Android flagships like the Galaxy and Pixel. Meanwhile, Samsung and Google wouldn’t exactly be thrilled to see this overview as they will need to up their game significantly with the Pixel 8 and Galaxy S24 series. Why not! Competition is what we need anyway.
With all that in mind, don’t forget that the vanilla iPhone 15 and iPhone 15 Plus are expected to reuse the 5nm A16 bionic chip from the iPhone 14 Pro, skipping the more efficient 3nm A17 Bionic. Obviously, this puts Apple’s vanilla flagships at a disadvantage for 2023, but it doesn’t mean that the cheaper iPhone 15 and iPhone 15 Plus won’t benefit from the bigger batteries that Apple is supposedly preparing. At all.
Larger batteries in iPhone 15 series may suggest faster wired/wireless charging, reverse wireless charging, and larger MagSafe battery pack for some iPhone 15 models

Could the iPhone 15’s larger batteries mean that some models are getting updates like faster wired/wireless charging, or even reverse wireless charging?
Bigger batteries are great, but what other improvements to battery and charging life could the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max bring? I’d like to take a moment and try to predict what the purported increase in battery size might mean for the rest of the hardware updates in the iPhone 15. Take everything with a grain of salt.
For example, I wouldn’t rule out the possibility of Faster wired/MagSafe charging on iPhone 15 compared to the iPhone 14. Don’t forget that USB-C is pretty much confirmed to be coming to the iPhone 15, which could easily facilitate a long-awaited increase in iPhone charging speed.
That said, I wouldn’t get my hopes up too much, as Apple (being Apple) will probably want to keep the same 50% charge in 30 minutes rule that Tim Cook & Co loves so much, meaning that iPhone series charging speeds 15 could be upgraded as the battery size increases, in other words, just enough. In practice, I don’t expect much more than 30W of wired/wireless charging across the iPhone 15 lineup.
I often use my MagSafe battery pack to wirelessly charge my (non-Apple) wireless earbuds, which is why I wish reverse wireless charging would finally come to the iPhone 15. exclusive to Pro models. Also, since the iPhone mini is no longer a priority for Apple, the company may also release a new larger MagSafe battery pack, made to fit the new smallest iPhone, the iPhone 15 by 6 .1 inch.
Looking at the battery size rumors and considering all the other updates coming to the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max, which one looks the most appealing to you? I have a feeling the bigger models could be an even bigger hit this year! But we will discuss this in a future story.
