How to Fix USB-C Charger Not Working on iPhone 15: 4 Ways

1. Choose the Appropriate iPhone 15 Charger

The iPhone 15 series ships with a USB-C cable on the box. However, it doesn’t come with the actual charger or wall adapter. 

Due to this, it’s crucial to get the correct charger for your iPhone 15 to avoid issues. 

The easiest route? Get the official USB-C wall adapter from Apple. While it would cost you more than third-party chargers, it’s guaranteed to work with the iPhone 15 series. 

If you don’t want Apple’s power brick, you can opt for third-party chargers but make sure only deliver up to 20W.

Why is my iPhone not charging with USB-C?

If your iPhone isn’t charging with a USB-C cable, first check your power adapter’s specifications to ensure it delivers no more than 20W. For the most reliable charging experience, I recommend using Apple’s official USB-C wall adapter.

Can I use any USB-C charger for my iPhone 15?

While any USB-C charger should theoretically work with the iPhone 15, there are known compatibility issues with third-party chargers. Currently, the iPhone 15 seems to only charge with adapters that provide 20W or less. Chargers offering a higher power delivery, such as 30W, are not charging the iPhone 15.

Why won’t my iPhone 15 charge when plugged in?

If your iPhone 15 isn’t charging, the issue could be with the charging cable or an incompatible wall adapter. Inspect the charging cable for any damage and ensure that the adapter you’re using is compatible with iPhone 15 specifications.

Will old iPhone chargers work on iPhone 15?

Yes, older USB-C wall adapters with a 20W power delivery should work with the iPhone 15 using the included USB-C to USB-C cable. However, be cautious when using third-party adapters; they should not exceed 20W power delivery for compatibility with the iPhone 15.
