But there's a difference between a device that's warm to touch and one that's overheating. We'll find out the reasons and discuss why your iPhone gets hot, along with how to diagnose and fix the problem.
When you use your devices for any length of time, it'll get warm. That's perfectly normal and shouldn't concern you. However, there are some activities that, when carried out for an extended period, may cause your iPhone or iPad to overheat. They include:
Charging and using your device at the same time. Streaming a high-quality video. Using GPS and real-time navigation controls. Setting up your device for the first time or restoring it from a backup. Using graphically demanding or processor-intensive apps. Leaving the device in a car on a hot day or exposing it to direct sunlight.When your iPhone or iPad is overheating, you'll also likely experience other issues such as:
Display dimming or going black intermittently. Poor call quality. Unusable camera flash. Graphic-intensive apps stop working properly or, worse, crash on launch. Temperature warning messages stating "iPhone needs to cool down before you can use it" or "Charging On Hold."
First, it's important to point out that no method can magically cool down an overheating iPhone or iPad immediately.
The suggested fixes below are mostly about adjusting how you use and care for your device, as well as tweaking some settings to prevent your device from overheating quickly during everyday use.
The first step is to temporarily stop using your iPhone or iPad so that your device can cool off properly. So, exit the app you're using, press the Sleep/Wake (or Side) button to put your iPhone or iPad to sleep, and leave it alone for 10 to 15 minutes to cool down completely.
To help speed up the process, you can also remove your iPhone or iPad case and turn off the device altogether.
To quickly reduce overheating, some people try putting their iPhones in the fridge or directly in front of an air conditioner. You should never do this because sudden changes in the temperature can cause condensation and damage your iPhone's internal components.
When the low battery notification pops up while you're using your iPhone or iPad, you probably just proceed to charge your device to continue using it. However, charging your iPhone or iPad while using the device simultaneously will cause it to overheat quickly, especially if you're playing a graphic-intensive game or using it for activities like video calls.
Unless it's an emergency, leave your iPhone or iPad to cool down, as mentioned earlier, and plug in only to charge your device afterward. In the future, it's best to maintain your iPhone's battery by planning ahead a little and ensuring that your device is fully charged beforehand.
Nowadays, our iPhones or iPads accompany us almost everywhere we go. However, when you're going somewhere without it, make sure you're not accidentally leaving your device in a place that's exposed to direct sunlight (like a desk next to the window) or in a car.
In the latter case, temperatures in parked cars can exceed the optimum temperature range and thus cause your iPhone or iPad to overheat. Remember to keep your iPhone or iPad in a shaded area so that they do not get hot due to external environmental factors.
Cheap third-party chargers purchased from non-certified sources can also cause your iPhone or iPad to get abnormally hot during charging.
It's best to use an official charger made by Apple or a high-quality third-party Lightning or USB-C cable that comes with the Made for iPhone (MFi) certification. Uncertified and fraying chargers can damage your device and create other problems.
Background App Refresh allows your apps to look for new information all the time. It happens automatically in the background, unknowingly consuming battery and CPU, which may result in your iPhone or iPad getting hot frequently.
If you're not a fan of this feature, you can turn off Background App Refresh by going to Settings > General > Background App Refresh > Background App Refresh > Off.
But if you think turning off this feature completely is overkill, you can try to catch the culprit app that's using the most power. Go to Settings > Battery to examine the battery usage of your apps for the Last 24 Hours and Last 10 days. Tap Show Activity for both the onscreen and background battery usage.
Then, go back to Settings > General > Background App Refresh. Toggle off the feature for apps that consume significant resources in the background.
If your screen brightness is above 50% or more, your iPhone or iPad will tend to stay warm at all times and will be more prone to overheating. Therefore, decreasing the brightness can help prevent your iPhone or iPad from getting hot quickly.
On an iPhone (or iPad) with Face ID, swipe down from the top-right corner of the screen to bring up the Control Center. If you have an iPhone with a Home button, swipe up from the bottom of the screen instead. Then, drag the brightness slider downwards as you see fit.
Updates often carry bug fixes and performance improvements that can help resolve the issue when your iPhone or iPad keeps getting hot. Go to Settings > General > Software Update to check if an iOS update is available. The same applies to third-party apps. It's best to head to the App Store to update your iPhone apps.
For example, many iPhone 15 and 15 Pro users initially found that their newly bought devices kept overheating. Apple identified that the cause was a bug in iOS 17 and quickly rolled out an iOS software update in response. In this case, make sure to update your iPhone to at least iOS 17.0.3 to prevent it from overheating.
In some cases, updating an app isn't sufficient to stop the overheating problem. You might need to uninstall and reinstall it again on your iPhone or iPad.
To uninstall an app, go to your Home Screen, long-tap it, and choose Remove App. Then, tap Delete App when you get a confirmation pop-up.
After uninstallation, you can reinstall the app on your iPhone or iPad. If this still doesn't work, you may also want to send an email to the developer for further investigation.
The last two methods here are generic but effective fixes that may help resolve a tech issue when all else fails. You can first restart your iPhone or iPad, which is simply turning off your device and turning it on again.
The other method involves resetting all settings on your device. This returns all settings on your iPhone or iPad to its default state. No data will be deleted, so you don't need to worry about losing your photos, videos, or messages.
To reset your device, go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. The resetting process can take a while, so it's best to attempt this when you don't need to use your iPhone or iPad urgently.
Your iPhone or iPad will feel warm to the touch after prolonged use, which is normal. If your iPhone or iPad is getting excessively hot, stop using it temporarily and give it time to cool down. At the same time, apply some of the tips discussed above to keep your iPhone or iPad at an acceptable temperature and ensure it doesn't overheat so frequently.
