iPhone 18 Pro Could Charge 25% Faster

Code found in iOS 27 suggests the iPhone 18 Pro and iPhone 18 Pro Max could support a 33% higher charging rate than the iPhone 17 Pro models, according to a new discovery from the leaker known as "pdfu."

The findings apparently come from Apple's charging optimizer settings buried in iOS 27, which show the iPhone 18 Pro and iPhone 18 Pro Max charging at a rate 33% higher than the iPhone 17 lineup. If Apple can maintain that higher rate throughout a charge, pdfu estimates it could cut around 25% off the time it takes to complete a typical fast-charging session.

Apple's first foldable iPhone does not appear to get the same treatment. The same code purportedly shows it charging at the same rate as the iPhone 17 and iPhone 17 Pro, rather than the faster rate expected for the new Pro models.

The research also points to further charging improvements arriving with future models. The standard iPhone 18 is said to match the iPhone 18 Pro faster charging, while the iPhone 18e is said to see an even bigger jump of around 69% over the current iPhone 17e. The iPhone Air 2 is said to charge about 27% faster than today's iPhone Air.

Actual charging speeds depend on a multitude of real-world factors, such as the phone's temperature and how full the battery already is, so the improvement buyers notice day-to-day could end up being smaller than the numbers suggest.

Apple is expected to unveil the iPhone 18 Pro and iPhone 18 Pro Max, along with its first foldable iPhone, at its "Surprise and shine" event today, while the iPhone 18e, iPhone 18, and iPhone Air 2 are rumored to follow in the spring of 2027.

Does a phone even exist that maintains the highest charge rate throughout the charging session? Nope. The heat alone would kill your battery. They start out high, and as charging progresses, the charge rate decreases down to just a few watts at the end. There is no way Apple would do this.

At this stage, the operating system matters more than the hardware. Most Android implementations provide much better functionality, including easier home screen icon arrangement, quick-access sidebar, app cloning, etc. These features greatly improve the user experience, and iOS still doesn't offer comparable capabilities in many of these areas. Oppo's ColorOS has all features that are missing in iOS.

No thank you. I still charge with an old school 5w charger using a usb-a to usb-c cable overnight. My battery stays nice and cool and degradation is limited….. I guess this is good in a pinch though, like if you forgot to charge your phone or just need a quick top up

Faster charging is very good to have. The 40W power adapter announced last year is still not available in my country. Hopefully Apple will launch it along with the new iPhones.

*but battery health degrades faster with fast charging and you have to buy anew charger.

So true. Always laughing about the people who actually post that, still babying their phone with the old 5W cube. I've had my 17PM since launch day, fast charging only and Coconut is displaying it at 101% after 270 cycles.
 
I wonder does this mean the iPhone 18 Pro models now support Power Delivery 3.2 SPR AVS at a charging rate of 60 watts steady instead of 40 watts steady? or Power Delivery 3.0 PPS at 60 watts steady?

Agree on the software. All of these features are sorely missed when I main my iPhone vs my Samsung.

Secure folder, split screen multitasking, real file manager etc. I feel like iOS in some ways is like how windows used to be. Windows used to make it hard for you to do basic things and introduce roadblocks. On a mac the same task was a drag and drop or a few clicks.

I feel like Android lets you do more and with ease vs some of the clunkiness of iOS.
