Important Note: If your iPhone gets hot and needs to cool down,  don't cool your iPhone by putting it in front of the AC, or in the refrigerator. Condensation can form inside your iPhone if you cool it too quickly, causing internal water damage. 

If your iPhone gets hot while using the Maps app, you may see an error message like the one above: Temperature, iPhone needs to cool down before you can use it. There are several general ways to fix things when your iPhone gets hot, including an update to the latest iOS, update apps you're using when your iPhone gets hot, delete and reinstall apps that are crashing, turn off background app refresh, and more.

Beyond the general issues that can cause an iPhone to get hot, there are a few specific things to check if your iPhone gets hot while using Maps.

Check Your Charger & Adapter

Lots of us use the Google or Apple Maps app while driving, and many of us use car chargers, as well. If your iPhone is overheating while using Maps and charging in your car, make sure that your charging cable and adapter are Apple certified. These accessories are more expensive, but you'll have peace of mind knowing that they're delivering a safe amount of power and not straining your iPhone. Look for the MFi badges below to identify certified third-party accessories.

Take Your iPhone Case Off

If you're not charging your iPhone while using Maps, or if your iPhone is overheating even with Apple-certified charging accessories, it's time to take off your case. This is because your iPhone cools off through its metal frame; a phone case slows this process, especially a thick or insulating one.

Turn Off Features You Aren't Using

This can be an annoying solution, because it requires you to change settings and turn features off and on, but if your iPhone gets hot even after following the steps above, it's time to turn off features you aren't using. First, open the Control Center of your iPhone:

  1. Tap the Bluetooth icon to turn off Bluetooth.

  2. If this doesn't help, tap the Wi-Fi icon to turn off Wi-Fi.

This is obviously annoying if you're trying to use CarPlay, or if you need Wi-Fi to run your Maps app. You can download Apple maps to use offline to make things a bit easier. You can also contact Apple Feedback to let Apple know how aggravating this is!
