There are a lot of leaks and rumors circulating as we approach the iPhone 15 launch. Four iPhone models are expected to be released by Apple, the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. According to a leak, the new phones are likely to receive a significant upgrade when it comes to charging speeds.

Despite Apple not officially promoting any fast charging figures with its iPhones, we know that the iPhone 14 Pro supports up to 27W fast charging and the iPhone 14 can fast charge at 25W. For the first time in the last two generations of iPhones, this figure is increasing quite a bit, according to 9to5Mac.

With the new iPhone 15 series, charging speeds could reach up to 35W. As of now, it is unclear which iPhone 15 models are capable of supporting this feature. Based on their predecessors, we expect at least the iPhone 15 Pro and iPhone 15 Pro Max to feature them. The iPhone 15 series did appear to have bigger batteries according to an earlier report from a rather shoddy source.

The iPhone 15 and iPhone 15 Plus could be upgraded to 27W if they both offer decent speeds while creating a decent amount of distinction between them. For their fast charging technology, Apple supports USB Power Delivery (PD) standards. All PD-certified adapters and cables on the market can fast-charge iPhones.
