The number of mobile phone explosions is increasing day by day. Most people think that overcharging is the only cause of a phone explosion, but the causes are quite different. Charger selection, high temperatures, and poor habits can all put significant stress on the battery. Therefore, it's crucial for everyone to be fully aware of the five main reasons why smartphones explode.

The combination of charging current and processor heat can cause the phone's temperature to exceed dangerous levels, leading to an explosion.

Human error is the primary cause of mobile phone explosions. Here are five key causes that 99 percent of people overlook, and how to avoid them:

1. Using cheap and counterfeit chargers
Often, when the original charger breaks down, people buy cheap, local chargers from the market. According to a report, these counterfeit charging accessories lack a voltage regulation circuit that controls the flow of electricity. This causes the phone to draw excessive current, which can cause the lithium-ion battery to overheat and explode. Always use original or brand-certified chargers.

2. Charging your phone on a soft surface.
Many people have the habit of charging their phone on their bed, sofa, or under their pillow while sleeping. This practice is very dangerous. Soft materials like mattresses and pillows trap heat inside the phone, preventing it from escaping. This constant heat buildup can cause internal damage to the battery. Always charge your phone on a hard, flat surface, such as a wooden table or floor.

3. Internal damage to the phone
When your phone falls from your hand, it may only appear as a broken screen or a scratch on the body, but internal damage can be serious. If the phone is hit or bent hard, the very thin membrane inside the battery can rupture. This can cause a short-circuit inside the battery and lead to a sudden fire.

4. Performing heavy tasks on the phone while charging.
Playing graphic-heavy games, streaming videos, or engaging in extended video calls while charging puts a lot of strain on the processor. According to The Times of India, the combination of charging current and processor heat can cause the phone to overheat to dangerous levels. This habit can lead to battery life loss and even explosion.

5. Exposure to excessive external heat.
During the summer, it's dangerous to leave your smartphone on the dashboard of a car parked in the sun, or near a gas stove in the kitchen. Extreme external temperatures disrupt the chemical balance in the battery. This can cause the battery to swell and increase the risk of thermal runaway significantly.
