So, what’s so special about this USB-C thing? Well, for starters, it can handle a lot more power than the old USB-A connectors. This means your devices can charge much faster, which is super handy when you’re in a rush.

For the very first time, Apple has put a USB-C connector on an iPhone. This is a pretty big deal because now, your iPhone can use the same charging cable as all your other devices.

But, hold on a minute, there’s a little catch. When you buy the iPhone 15, it doesn’t come with a charging brick. Apple gives you a USB-C to USB-C cable, but that’s it. So, if you don’t already have a USB-C charger, you would need to buy one.

According to Apple, if you use a 20W USB-C power adapter, you can charge your iPhone 15 from zero to 50% in just about 30 minutes.

Technically, the USB-C port on the iPhone 15 can handle up to 27 watts of power. But here’s the catch: once you go above around 20 watts, the increase in charging speed starts to slow down. It’s like trying to pour water into a bottle with a tiny opening.
