While the source of this information remains unverified, the claim is plausible, given the previous charging capabilities of Apple’s iPhones. There were pre-launch reports hinting that some iPhone 15 models might support 35W charging. However, if that were the case, one would expect Apple to mention 30W chargers in its official statement instead of 20W ones.
Comparing Charging Speeds
If the reported charging speeds apply to all four iPhone 15 models, it would represent a modest increase compared to the iPhone 14 series, which charged at approximately 25W in independent tests. However, it would also mean that the iPhone 15 Pro Max matches the charging power of the iPhone 14 Pro Max.
