Maximum Watt charging for iPhone 13?

Fast charging your iPhone with a cable requires a 20W power adapter. Fast charging with MagSafe requires 15W. But there is no point in buying a higher watt power adapter than that because it will charge your iPhone the same. You also cannot overcharge your iPhone as it regulates the charge that goes into it.

With your 22W power adapter you already are fast charging.

I use a 22whatt charging brick and an Apple cable. I heard that phones have a maximum whatt charging. I would love for my phone to charge at its fastest. What is the iPhone 13’s? Does it affect battery life?

thanks

For an iPhone 13 you need 20 watts or more for fast charging. There is no upper limit in wattage rating, however, as the device will only draw what it needs. So you can use an Apple 91 watt adapter, or even higher. There is no downside to using a higher rated adapter if you have one.

A 22-watt adapter is fine.
