iPhone 15 and iPhone 15 Pro models are capable of up to 27W peak charging speeds with an appropriate USB-C power adapter, according to Japanese blog Mac Otakara. It is unclear where the website sourced this information from, but it seems to confirm that the iPhone 15 Pro models have the same maximum charging speeds as the iPhone 14 Pro models.


In August, 9to5Mac reported that at least some iPhone 15 models could support up to 35W charging speeds, but this rumor appears to be incorrect.

Just like the iPhone 14 models, Apple says all four iPhone 15 models can charge up to 50% in around 30 minutes with a 20W or higher power adapter.

Last year, the website ChargerLAB determined that Apple's 30W USB-C power adapter was the company's lowest-priced charger that could charge the iPhone 14 Pro models at their maximum charging speeds of up to 27W, and this will likely remain the case for the iPhone 15 Pro models. In the U.S., the adapter is priced at $39 on Apple's online store.

Real-world tests still need to be completed, but for now it appears the 35W rumor was wrong.

All of the new iPhone 15 models launch on Friday, September 22.

A rumor disproved a prior rumor? ha ha ha ha ha. Who writes this crap?
Yo dawg, there's a rumor going around that this other rumor is a bust. Stay tuned for more rumors...

There is nothing to indicate that Mac Otakara's report is a rumor. They are straight up reporting that it is 27W, not 35W.

Source is probably reviewers. Hundreds of them are reviewing the devices right now.

When Apple finally adopts vapor chamber cooling, the wattage will probably increase. We've seen how 27W affects iPhone 14 Pro battery health. Bumping that up without cooling might not be a good idea.

I care less about W rating on charging and more about effective results. If at 27W the damn thing throttles (which mine does quite a bit, and I live in a relatively cool climate, and even go so far as to throw the phone on an ice pack when charging, esp when wireless charging, about the only way to get it to charge at max the whole charging curve), I really don't actually want the 35W charging (because that's just spec sheet fun), I want the thermals to improve to maximize the 27W output first along the whole charging curve without having to ensure it's on an ice pack or in a very, very cold room shielded from all possible sources of light/heat.

Hell, take my 27W away but give me 15W but with thermals that keep the throttling at bay.

Hopefully Ti's (on paper) heat dissipation advantage over SS gets us something here (although the internals remain Al....the frame/Ti join does seem to be non-fastener related and is friction welded it appears, which also in theory is good for thermal conductivity).

I hope they can verify this soon. I want to get a USB-C car charger that can fast charge my 15 Pro Max.

So the 35W was a rumor?
Well, newsflash, rumors don’t always come true…
Amazing into which n-th level of feature detail we get nowadays to create excitement or disappointment…

This one was the biggest disappointment for me
Isn't 27W charging still pretty fast though?

Personally, I have never been in a situation that I ran down the battery in critical low and needed to top off within minutes. The Apple 20W USB-C charger remains the best choice.
Most of the time I just lay my phone down on a slow, basic Qi charger while I'm asleep. It may take 3 hours to charge, it may take 7. It doesn't matter because it'll be done by the time I wake up :)
