With the transition to USB-C, the iPhone 15 models could get faster charging speeds up to 35W. 9to5Mac says that it has heard from industry sources that "at least some" of the iPhone 15 models are able to charge at this higher wattage.

At the current time, the iPhone 14 models can charge at a maximum of around 27W, with the Pro models able to charge a bit faster. An increase to 35W would speed up charging times.

Apple does not sell a power adapter with the iPhone anymore, but the company recommends a 20W+ charger for fast charging purposes right now. If the iPhone 15 models support up to 35W charging, Apple could start recommending its 30W MacBook Air charger or its 35W Dual USB-C charger for maximum charging speed.

Earlier this year, Apple analyst Ming-Chi Kuo said that the iPhone 15 models would support faster charging speeds due to the transition to USB-C. He said that the faster speeds would be available with MFi-certified USB-C chargers, including the 20W power adapter.

There have been rumors that Apple will limit faster charging speeds to MFi-certified cables and chargers, and it is also possible that the fastest charging speeds could be reserved for the iPhone 15 Pro models.

I hope EU will ban devices with charging speed limitations enforced by the MFi if Apple goes this way.

I doubt my current MacBook USB-C cable and charger is equipped with MFi chip and it seems absurd not being able to fully use my MacBook original charger and cable (which works just fine with my iPad Pro) for the new iPhone.
 
I hope EU will ban MFi limits enforced by MFi if Apple goes this way.

Ironically, the MFI program might be necessary for compliance with the upcoming EU Cyber Resilience Act as it is a way for Apple to help secure devices from USB-based attack vectors.

That being said, I do agree Apple should not be artificially limiting charging and connection speeds to only MFI-approved cables.

Definitely not for charging. For other peripherals? Sure.

And also EU will choose some more open standard than Apple locked one for sure.

Edit: reaction to your edited message: there's not attack vector for charging. Charging cable is dumb and should not use data pins. So EU Cyber Resilience Act is not relevant for this case. It is however relevant for peripherals which actually use some driver (HID devices, mass storage devices etc.)

I can almost understand keeping lightning at USB 2 speeds because then all the cables and all the phones do exactly the same thing. It would be a real shame for Apple to start making USB-C connections pay-to-play when it comes to speeds. All the models should be whatever is the fastest that can safely operate the battery and the phone. Otherwise they are doing more to make the Apple ecosystem confusing to unsuspecting buyers.

Edit: As USB-C speeds increase, so does the phone, and that is the progression of technology. But from phone to phone in the same year is just nickel and diming.

Edit 2: There should be a software setting to limit charging if someone wants to charge slower than the max capable.

Awesome! Let’s just keep decreasing battery health quicker for they upgrade quicker. Genius!
There's no risk in charging 35W these days. The battery life will not decrease significantly more compared to super slow 5W charging.

You will sooner buy new phone anyway because it will be morally obsolete.

Also it is technically possible to limit charging speed via software.
 
This is why I am starting to wonder if the real USB Type C connector specs for the iPhone 15 models are:

iPhone 15/15 Plus: USB 3.2 1x1 (5 Gbps Certified) with up to 27 watts initial charging rate
iPhone 15 Pro/15 Pro Max: USB 3.2 2x2 (20 Gbps Certified) with up to 35 watts initial charging rate

The higher the wattage, the higher level of heat and battery degradation.

iPhone 12 Pro - 24W
iPhone 13 Pro - 27W
iPhone 14 Pro - 29W

It’s no coincidence some people with iPhone 14 Pro are reporting poor battery health after a year with 30W chargers.

My phones have been well with wireless MagSafe charging puck and optimized charging on for overnight finishing in morning before I get phone. Still at 97 percent health with this method
