Upgrade Your Charger and Cable
If you actually want to take advantage of your iPhone’s fast charging, you’ll need to get the right charging brick and cable. Apple no longer includes a charger with a newer iPhone. So if you purchase the iPhone 13, you’ll have to get the charger on your own.
There are many great chargers for iPhone you can get right now, but if you’re not sure which one to get, make sure it’s a 20W charger. This will be more than enough to fast charge any iPhone you have.
