Sudden explosion! Mobile phone becomes a "grenade"? Beware →

Recently, Shenzhen, Guangdong

A father holding his child

The phone in my pocket suddenly started smoking

To help children avoid danger

The man immediately bent down and tried to put the child down.

In a panic, the man accidentally dropped the child to the ground, causing the child's head injury and arm burns. The man's thigh was also burned. The smoking mobile phone caught fire within seconds after it was taken out. Fortunately, the man quickly extinguished the fire and no more serious consequences were caused. It is understood that the mobile phone had been replaced with a non-original battery .

Why do cell phones explode?

1. Internal reasons : If there are defects inside the battery, it may explode even when it is not charging or discharging.

2. Long-term overcharging : Lithium batteries may discharge instantly and generate a large amount of current under special temperature, humidity and poor contact conditions, causing spontaneous combustion or explosion.

3. High temperature environment : Batteries are generally not resistant to high temperatures. If the phone is placed in a high temperature environment or near flammable items, it may cause an explosion.

4. Mixing chargers : The battery capacities of mobile phones of different brands vary. If a high-power charger is used to charge a small-capacity mobile phone battery, there is a certain safety risk.

5 signs before your phone explodes

1. The phone is getting hot

Sudden heating : If the phone suddenly becomes hot during use, stop operating it immediately. Most mobile phones will suddenly become hot before exploding.

The phone becomes hot when making a call : If the phone starts to get hot shortly after a call, be cautious, as there may be a problem with the battery.

2. The phone cannot be charged

If your mobile phone always fails to charge, after ruling out the possibility of a damaged charger, it can be basically determined that there is a problem with the phone's battery and it should be sent for repair immediately.

3 Frequent automatic start

Frequent restarts will keep the phone in a fast-running state for a long time, which can easily cause the phone to overheat and cause an explosion.

4. Data cable is damaged

Some old and low-quality charging data cables will have surface damage and internal insulation aging due to long-term use. Using a damaged data cable to charge is not only prone to short circuits and fires, but also may cause leakage when the metal wires inside the data cable are exposed, which is dangerous.

5. The battery appearance changes

If the surface of the mobile phone battery swells or even leaks liquid , it is a sign of aging and damage of the mobile phone battery. If such a phenomenon occurs, it is recommended not to use the mobile phone, let alone charge the mobile phone. The mobile phone should be sent for repair in a timely manner under safe conditions to avoid accidents.
