The editorial team at TechInsider, a technology publication, has noted an increase in reports of swollen batteries in smartphones. In response, they have prepared an article listing the main causes of this battery defect.

Firstly, it is essential to follow the proper usage guidelines for the battery. Do not leave your phone charging overnight, as this can lead to overheating and damage to the battery components. Additionally, it is recommended to avoid fully discharging the battery before recharging it.

Another important factor is the physical condition of the device. Drops and strong impacts can cause cracks in the battery or the smartphone's casing, which in turn can lead to battery swelling. Therefore, it is crucial to protect your device from mechanical damage.

Environmental conditions should also be considered. High temperatures and humidity can negatively affect the battery's performance, so it is not advisable to use your smartphone in extreme conditions, such as in a sauna or in freezing temperatures.

Finally, manufacturing defects can also cause battery swelling. When purchasing a new smartphone, it is essential to check for defects and the manufacturer's warranty.

If your smartphone's battery has already started to swell, you should immediately disconnect it from the power source and remove the battery if possible. It is also recommended to place the device in a plastic bag and take it to a professional for further diagnosis and repair.
