If your device starts shutting down or shows a message saying it needs to cool down before turning back on, it’s likely experiencing hardware overheating. This usually happens because the phone’s internal temperature gets too high. When this occurs, your device will turn off to protect itself, and it may take about an hour or more to cool down enough to use again. If this happens, you should contact Apple support — they offer options like callback or chat to help you get your device fixed.
If you’re not seeing any of these signs, your phone hasn’t overheated. However, fast charging can make your device warm. When you use fast charging, the phone may pause charging once it reaches 80%, showing a message that charging has been paused. It will automatically resume when the device cools down. This is normal and doesn’t mean your phone is overheating or in trouble. Plus, it won’t prevent you from using any apps.
After updating your iOS, give it a couple of days to finish background tasks such as rebuilding search indexes or updating app data structures. During this time, your device might feel a little warmer than usual. That’s normal as the system is getting everything set.
Certain apps can cause your phone to heat up a little more. Apps that use a lot of energy or rely on cellular data instead of Wi-Fi tend to be bigger culprits. Examples include social media apps like Facebook, WhatsApp, Instagram, streaming services, games, or apps that use your camera, like TikTok and Snapchat. Using your device while charging can also generate heat. If you have a VPN installed, even if it’s not active, it can also increase energy use and heat.
Some apps have been known to cause more heat than necessary, especially if they’re not well-optimized. For example, older versions of the Amazon app or Words With Friends 2 have been reported to make iPhones warmer. Sometimes, app updates released around the same time as iOS upgrades can also cause a temporary increase in temperature. You can check for updates in the App Store to see if there are newer versions that fix these issues.
Remember, these behaviors relate to the fundamental laws of physics, where heat is a natural part of how devices work when they’re under heavy use. To keep your device running smoothly and safely, avoid using it in extremely hot environments, and give it breaks if it starts feeling warm. If overheating happens frequently or your device shuts down unexpectedly, reaching out to Apple support is the best move for professional help.
