An iPhone 15 Pro Max battery charging test shows how fast USB-C charging is on the new iPhones — check it out.
You might have hoped that Apple increased battery charging speeds on the iPhone 15 models because they come with USB-C charging ports instead of Lightning, but that hasn’t happened. Instead, Apple’s latest iPhones have the same official max charging speed of 20W from previous models.
That also means that all iPhone 15 models will actually top that 20W speed if you have a compatible charger. It’s what Apple did with the iPhone 13 and iPhone 14. Speeds can surpass 25W, so you can get the iPhone to charge faster with a power brick that supports at least 30W. But how much faster are we talking about?
The following test shows how fast the iPhone 15 Pro Max takes to charge over USB-C with several different Apple chargers. It might help you decide which accessories to buy next.
YouTuber Brandon Butch conducted the test. He used 5W, 12W, 20W, and 30W chargers that Apple sells. The 5W wall adapter is the default iPhone charger Apple used to offer buyers for free. The 30W charger is something you’d use with the MacBook Air, as that’s the power brick that ships with base models.
