1. Common causes

Several factors can explain why a smartphone overheats. In most cases, it is caused by heavy usage or a software-related issue.

The most common causes include:

• prolonged use of games or resource-heavy applications

• exposing the phone to direct sunlight

• too many apps running in the background

• a system update in progress

• fast charging or charging with a non-official cable

• an aging battery

All these situations put heavy pressure on the processor and battery, which increases the device’s temperature.

If several of these situations occur at the same time, the phone may overheat significantly. This can cause the device to shut down for safety reasons, or at least lead to bugs, freezes, and slow performance.

For example: if your phone is used as a GPS, connected to a charger, and placed on the dashboard under direct sunlight, overheating is almost guaranteed. It’s a classic situation.

2. Applications

Some applications are particularly demanding in terms of resources: games, streaming apps, and certain social media apps.

If your phone heats up quickly, check:

• the apps consuming the most battery

• apps running in the background

• app updates currently in progress

In some cases, poorly optimized apps can cause constant overheating. Having too many apps open in the background can also raise the phone’s temperature.

3. Possible hardware problem

If overheating becomes frequent, the issue may also be related to hardware.

When charging, your smartphone will naturally warm up slightly. However, if it becomes very hot, that is not normal. The battery may be defective and should be replaced quickly at a specialized repair shop.

The most common hardware-related causes are:

• a worn or defective battery

• an incompatible charger

• processor issues

• an older phone struggling with modern apps

If your phone becomes extremely hot even when idle, it may be necessary to have the battery checked or consider replacing the device.

My Charger Gets Very Hot

If it’s your smartphone charger that heats up, that is fairly normal. However, you should still be able to hold it in your hand. If the charger becomes burning hot, that is not normal. It may be of poor quality or reaching the end of its life, which can be dangerous.

In that case, unplug it immediately and replace it with a new charger. Generic chargers can be fine, but avoid very cheap models. As often mentioned on Premiers Clics, good-quality generic products do exist.

4. Solutions to cool down your Smartphone

Fortunately, there are several simple solutions to prevent overheating.

Here are the most effecative actions:

• close unnecessary applications (tap the three vertical lines at the bottom to see open apps)

• remove the phone case while charging

• avoid direct sunlight

• disable unused Bluetooth, GPS, or Wi-Fi

• restart the phone regularly (hold the power button + volume up)

• keep the system updated

These actions reduce processor load and help protect the battery.
