A smartphone can catch fire in your pocket: how to avoid the danger and what signs to watch out for.

The risk of a smartphone catching fire increases due to overheating, mechanical damage or a faulty battery. The danger is greater in heat and during intensive use of the device, especially when the phone is in tight clothing and heat cannot dissipate.

Under what circumstances can a smartphone catch fire in your pocket

Overheating most often occurs during the launch of 'heavy' applications, navigation or taking photos. In high ambient temperatures or if cooling is insufficient, the casing heats up faster, which increases the likelihood of combustion.

A separate risk is mechanical impacts. A strong impact or prolonged pressure (for example, when carried in the back pocket) can deform the battery and provoke a short circuit, even leading to a fire.

Additional risk factors include:

• a swollen battery - a sign of internal damage that can lead to overheating;
• a worn-out battery - over time it loses stability, and chemical processes become less predictable;
• unexpected overheating - heating without load or sudden shutdowns are a reason to check the battery's condition;
• non-original components - cheap chargers and power supply units may not meet safety requirements.

If you notice a swollen battery or significant heating without obvious reasons, it is advisable to diagnose the smartphone as soon as possible - this will help prevent serious consequences.

Recall that record heat poses a threat not only to people but also to smartphones, which can overheat quickly and shut down. To prevent damage to the battery and internal components, it is advisable to provide the device with cooling conditions in advance.

We also wrote that throttling is a built-in mechanism that automatically reduces the processor speed during overheating. Thanks to this, the smartphone maintains its operability even under intense load.
