Here are some tips that can help you protect your device from overheating, according to the Indian Express:
Never leave your phone in the car unattended
During the summer, the car can act as a heater to which heat flows through the windows due to sunlight, raising the temperature inside to a much higher level than outside.
According to a paper published in the journal Tempreture, a car parked in the shade in the summer can raise its interior temperature to dangerous levels in just two hours, so avoid leaving your phone in the car while it is parked.
Avoid exposing your phone to the sun for long periods
Just as with humans, your phone can also be prone to overheating if left in direct sunlight for extended periods of time. This can be exacerbated if your phone is left to charge in a place where there is direct sunlight. Combined heat from charging and sunlight can cause serious long-term damage to the internal parts of the phone.
Close power-intensive apps when you don’t need them
Some apps that are running simultaneously in the background of your smartphone may be very power intensive, draining your phone’s battery and heating it up at the same time. Go to the battery usage tool on your phone to see which apps are using the most battery. Once you have identified these apps, close them and prevent them from running in the background. This will greatly reduce the workload of your phone and thus prevent overheating.
If the phone overheats, remove it from its protective case
Phone cases come in different designs from different manufacturers. This means that not all of them are designed in a way that matches the thermal engineering of a smartphone. Even if it is, it acts as a layer of thermal insulation that prevents heat from dissipating. If you notice your phone overheating, try taking it out of the protective case to give it a little room to breathe. This may help the heat dissipate faster.
Consider buying a cooling fan for your phone
If you routinely play games on your phone, or use it for high-performance tasks, it is best to buy a cooling fan for your phone. Cooling fans for phones come in many different designs targeting different use cases.
