Have you ever noticed that your phone gets really hot after using it for a while? You're not alone, and while a little heat is normal, when your phone gets too hot, it can be a sign that something is wrong. Here are the three most common reasons why this happens.

Intensive processor usage and demanding applications: When you run graphically demanding games, use the camera to record long videos, or have many applications open at the same time, the processor (CPU) and graphics card (GPU) work at full capacity. This generates heat because these components consume a lot of energy, and their operation generates internal friction that raises the temperature. Poorly optimized applications or malware can further increase this load, causing the phone to overheat for no apparent reason.

Phone charging and simultaneous use: One of the most common situations is using the phone while it's charging. The battery and charging circuit produces heat, and if you add to that using the phone to browse, play games, or watch videos, the temperature can rise rapidly.

Furthermore, fast or wireless charging also generates more heat than traditional charging, so if you use these technologies on devices without good heat dissipation, the problem is exacerbated.

Environmental conditions and physical protection: It's not uncommon to leave your phone in the sun or in a hot place, like the car, which causes the device to heat up. even without heavy use. Additionally, some protective cases or covers can trap heat instead of dissipating it, especially if they are thick or made of insulating materials. This limits the device's ventilation and causes heat to build up inside.

How does increased temperature affect the phone's battery?

Heat is one of the worst enemies of modern batteries, which are mostly made of lithium-ion. Although batteries can operate within a safe temperature range (usually between 0 and 40 degrees Celsius), several negative effects occur when this temperature is exceeded.

First, Heat accelerates the internal chemical degradation of the battery. At high temperatures, electrolytes and other components break down,generating gases and increasing internal pressure. This reduces the battery's capacity to store energy and will significantly decrease usage time between charges. Furthermore, when the battery heats up while charging or discharging, its lifespan is reduced by half or even more quickly. For example, charging at 45 degrees Celsius can cause the battery to age much faster than at room temperature, meaning your phone will need a battery replacement sooner. In extreme cases, overheating can even cause deformation, leaks, or irreparable damage leading to critical device failure. Finally, in addition to physical and chemical damage, the phone's software may limit performance to prevent further damage. This means your phone might run slower or shut down unexpectedly when the temperature gets too high, in an attempt to protect the battery and hardware.

Practical Tips to Avoid Overheating and Take Care of Your Phone

To avoid dealing with a constantly hot phone and extend battery life, here are some simple but effective tips:

By following these tips, you'll reduce overheating of your device, prolong battery life, and prevent your phone's performance from being affected by excessive heat. Remember that an overheating phone is not only uncomfortable to use, but it also shortens the life of one of its most expensive components: the battery.
