Why Do Phones Get Hot?

Your phone is a tiny computer. Just like a laptop, it creates heat when it works hard. The more tasks it performs at once, the warmer it can get. Heat can also come from your battery, your charger, your apps, or your environment.

Common reasons your phone gets hot include:

• Running too many apps at once
• Poor Wi-Fi or cellular signal
• Playing games or watching videos for long periods
• Using GPS or Bluetooth for extended time
• Charging with a damaged cable
• A battery nearing the end of its life
• Low storage or outdated apps
• Malware or scam apps secretly running in the background

If you want to understand performance issues more deeply, you may find How to Tell What’s Slowing Down Your Phone especially helpful.

When Should You Worry?

A slightly warm phone is normal.

But if your device feels hot, shuts itself down, or gives you a temperature warning screen, it’s important to take action. Overheating can:

• Reduce your battery life
• Slow your phone down
• Permanently damage internal components
• Cause apps to crash
• Interrupt calls, photos, and messages

Immediate Steps to Cool Down an Overheating Phone

If your phone feels hot to the touch, try these simple fixes right away:

1. Turn it off for a few minutes

Powering down the device gives it time to cool and stops all background activity.

2. Remove the case

Phone cases trap heat. Removing the case allows the device to release warmth more quickly.

3. Stop charging

If your phone gets hot while plugged in, unplug it immediately. Charging issues are a common cause—especially if the cable is worn or the outlet is loose. To better understand charging behavior, see How to Tell If Your Phone Is Charging Properly.

4. Close apps running in the background

Apps like navigation, social media, or video streaming can keep running even when not in use.

5. Move it out of direct sunlight

Cars, patios, and windowsills can heat a phone extremely fast.

6. Switch from cellular data to Wi-Fi

If your phone is struggling to find a signal, it works harder and heats up. Learn more from What’s the Difference Between Wi-Fi and Cellular Data?.

7. Disable features you aren’t using

Turn off Bluetooth, GPS, or hotspot if you don’t need them.

What Causes Overheating? A Complete Breakdown

Let’s look deeper into the most common causes of a hot phone—and what you can do to fix them.

1. Too Many Apps Running at Once

Apps use your phone’s memory and processor. The more apps you switch between, the harder your phone works.

Symptoms of app overload include:

• Slow performance
• Screen stuttering
• Apps freezing or closing
• Battery drain
• Heat building from the back of the device

For more guidance, see What’s Slowing Down Your Phone.

2. Low Storage Space

Phones with low storage must constantly work to manage files, which creates extra heat. This is extremely common.

Free up space by reviewing:

• Old apps (see How to Delete Old Apps from Your Phone)
• Large videos
• Old text message threads
• PDFs and documents (see How to Download a PDF from an Email or Website)
• Screenshots (see How to Take a Screenshot (and Find It Later))

If you’re not sure how much storage you have left, start with How to Find Your Phone’s Storage Limit.

3. Old or Damaged Battery

Phone batteries naturally wear out. As batteries age, they generate more heat under normal use.

Signs your battery may be weakening:

• Phone drains too quickly
• Phone charges inconsistently
• Phone gets hot even with light use

Learn more about battery behavior in Why Your Phone Battery Dies So Quickly.

4. Poor Signal or Network Problems

If your phone is searching for Wi-Fi or cellular signal, it ramps up its internal components, which generates heat.

If your connection drops often, see What to Do When Your Wi-Fi Keeps Dropping.

5. Long Video Calls or Streaming

Video apps use:

• Cameras
• Screen
• Microphone
• Wi-Fi or cellular data

All at the same time. It’s normal for a phone to warm up during long video calls.

6. GPS and Navigation

Navigation apps continuously update your location, download map data, and track direction. This is extremely intensive—especially while driving.

You can reduce heat by ensuring your maps app is updated (see What’s the Best Way to Update Your Phone’s Apps?).

7. Scam Apps or Suspicious Activity

Sometimes a phone overheats because an app is secretly running in the background, using your data or processing power.

This can happen if:

• You clicked a suspicious link
• You installed a fake app
• A scam text tricked you into downloading something

8. Charging the Phone Incorrectly

Your phone naturally warms during charging. But overheating during charging can signal a problem.

Common causes:

• Cheap or worn charging cables (PLACEHOLDER, TechPals may earn a small commission at no cost to you)
• Plugging your phone in under a pillow or blanket
• Charging in a hot car
• Using the device heavily while charging
• Charging from unstable outlets
