While it's true that lowering the temperature of a device can help in dissipating heat and potentially cooling it down, putting your phone directly in the freezer is not recommended. Freezing temperatures can have adverse effects on electronic devices, including smartphones.
Exposing your phone to extremely cold temperatures can cause condensation to form inside the device when it is taken out of the freezer and exposed to warmer air. This condensation can damage the internal components of the phone, leading to potential malfunctions or even permanent damage.
If your phone is overheating, it's generally better to employ other methods to cool it down. You can try turning it off for a while and letting it cool down naturally at room temperature. Additionally, avoid using your phone while it's charging or in direct sunlight, as these factors can contribute to increased heat generation.
If your phone consistently overheats or experiences cooling issues, it's advisable to consult the manufacturer's guidelines or contact their customer support for assistance.
