Here’s What To Do When Your Phone Gets Hot

Your phone may warm up occasionally, but it should never become uncomfortably hot. If it overheats, cooling it down is crucial to prevent damage. Here are the most effective solutions to help you cool a hot phone, starting with the simplest one.

Remove the Case from Your Phone

If your phone is overheating and you have a case on, the first thing you should do is remove the case. According to Joule's law, all electronic devices, including your smartphone, generate heat when they’re working (turned on). When a case is on your phone, it can prevent the heat from escaping effectively, causing the device to overheat.

This is especially true if your case is made from an insulating material such as silicone, rubber, or thick plastic. The worst part is that the case can mask the heat buildup, so you might not even realize your phone is getting hot until the screen starts feeling warm. At that point, your phone is probably already overheating, so remove the case quickly and let it catch some air.

Close All Open Apps and Background Apps

Every time you open an app on your smartphone, it uses the CPU and memory, which in turn generates heat. So, closing all open apps can help reduce overall heat generation.

When you simply swipe up and exit an app, you aren’t actually closing it—instead, it’s still running in the background. If you open and exit multiple apps, you end up with many minimized applications, all contributing to heat generation. As such, if your phone starts to feel hot, go into the multitasking menu and check if you have a lot of apps running. If yes, swipe them away, and it should help cool down your phone.

Restart Your Phone

If your phone is still hot after closing all the apps, consider restarting it or turning it off. Similar to background apps, there are background processes that also contribute to resource consumption and heat generation.

For example, Instagram will run a background process, so you receive notifications even if the Instagram
