Phone Overheating Issue: According to mobile experts, a phone’s battery bears the brunt of the damage when the device overheats. Prolonged exposure to high temperatures causes the battery’s capacity to degrade over time.

Phone Overheating Issue: The summer season is currently underway, and its effects are being felt not only by humans but also by our electronic devices. During the summer months, smartphone overheating has become a common issue. Often, a phone gets so hot that it becomes difficult to even hold it in one’s hand. Factors such as continuous gaming, video recording, using the device while charging, or leaving it exposed to direct sunlight can cause the device to heat up rapidly. In several instances, reports of phones exploding or catching fire due to overheating have also surfaced. Given this, let us explain which component is the first to fail when a phone overheats excessively during the summer, and how you can prevent this from happening.

The Battery Fails First

According to mobile experts, the battery is the component most adversely affected when a phone overheats. Prolonged exposure to high temperatures leads to a gradual decline in the battery’s capacity. Often, the battery begins to swell, starts draining rapidly, or causes the phone to shut down unexpectedly. If left unaddressed in a timely manner, the overheating can damage not only the battery but also the motherboard and the processor. This is precisely why taking the issue of overheating lightly can prove to be a costly mistake.

What Causes a Phone to Overheat?

Among the primary reasons for a phone overheating are playing games for extended periods, recording high-resolution videos, continuous video streaming, running multiple apps simultaneously in the background, and using the internet in areas with poor network coverage. Additionally, using the phone while it is fast-charging, utilizing generic or old chargers, and having a full storage capacity can also cause the device to heat up. Many users tend to place their phones on soft surfaces—such as a bed or a blanket—while charging; this prevents heat from dissipating effectively, causing the device’s internal temperature to rise rapidly.

Intense Sunlight and Hot Environments Can Pose a Risk

Tech experts warn that during the summer, exposing a phone to direct sunlight or leaving it inside a car can be extremely dangerous. People often place their phones near a refrigerator or ice in an attempt to cool them down quickly. However, doing so can actually prove harmful; sudden temperature fluctuations cause moisture to condense inside the phone, which can damage its internal components.

What to Do Immediately If Your Phone Overheats

If your phone becomes excessively hot, the very first step is to disconnect the charger. Next, you should remove any thick back cover from the phone to allow heat to dissipate easily. Placing the phone in Airplane Mode or switching it off completely for a while is also considered a beneficial measure. In areas with weak network coverage, a phone constantly searches for a signal; this places increased strain on the battery and processor, causing the device to overheat. In such situations, temporarily disabling mobile data or the cellular network can also help.

Android Users Should Adjust These Settings

Android users can disable Wi-Fi scanning and Bluetooth scanning. Revoking location and microphone permissions when they are not needed can also be helpful. Additionally, on phones equipped with a 120Hz display, lowering the refresh rate to 60Hz reduces battery consumption and helps keep the device cooler. If your phone supports fast charging and is experiencing persistent overheating issues, it is advisable to disable this feature during the summer months.
