We have compiled a list of 8 such reasons which are responsible for phone blasts. Along with this, we will also tell you here what you can do to avoid such incidents. So let's know about the causes of phone blasts and ways to avoid them.

The recent incident of the OnePlus Nord 2 blast might have made you think once again that why do smartphones explode. To answer this question, we have prepared a list of 8 such reasons which are responsible for phone blasts. Along with this, we will also tell you here what you can do to avoid such incidents. So let's know about the causes of phone blasts and ways to avoid them.

1. Manufacturing Fault
The main reason for the breakdown of the phone is the fault in the manufacturing. The lithium-ion battery that powers the handset needs to be thoroughly tested before it can be fitted to the phone. If any fault occurs during assembly then the phone may explode. This usually happens when the cells inside the battery reach a critical temperature. This leads to thermal runaway. It is said that cheap batteries are more prone to short circuits.

2. Physical damage
Another reason why the phone explodes is the physical condition of the battery. Sometimes when the phone falls, it can damage the battery. This can change the internal mechanical and chemical structure of the battery which is likely to cause short-circuits, overheating, and much more. Once a battery wears out, it often swells. In this case, it is better to replace it. In case this happens the phone should be immediately taken to a service center.

3. Using a Third-Party Charger
This is a common mistake that most of us make. Apart from the original charger, if you charge the phone with any other charger then it can be dangerous. Third-party chargers often lack what your handset requires. Although many chargers may look like your original charger, they can damage your phone, and damage your phone's battery. Many times incidents of phone blasts through third-party chargers have also been seen.

4. Overnight Charging
Besides using third-party chargers, there are other reasons why the battery may overheat. One of the main reasons is the overnight charging. Most of us have a habit of putting the phone on charging while sleeping. Due to this, the battery becomes prone to overheating, overcharging, short-circuiting, and sometimes explosion. Many smartphones now come with a chip that stops the flow of current when the battery level is 100 percent. However, there are still some affordable handsets in which this feature is not provided. In such a situation, keeping such smartphones charging overnight can prove to be dangerous.

5. Processor overload
The processor plays an equal part in overheating or overheating your phone. Thermal issues have been seen in many chipsets of the phone while multi-tasking and running heavy graphics apps like PUBG. To avoid this many OEMs have started adding thermal lock features or thermal paste to keep the heating problem of the handset under control. But in many cases, this maneuver also fails and the thermal lock stops working and the phone explodes. In such a situation, forcefully loading the phone should be stopped so that you can get rid of the problem of blasting with smooth processing.

6. Problems like keeping the phone in direct sunlight or leaving it in the car
Excessive heat can damage the phone battery. This causes the cells to become somewhat unstable and lose exothermic breakdown. At the same time, gases like oxygen and carbon dioxide are produced. These gases can swell the battery and cause the battery to explode. Hence, it is advisable not to leave the handset in the car and also not to keep it in direct sunlight for a long time.

7. Battery Exposure to Water
When the handsets were not waterproof, there were many tales of battery explosions due to water. But even the most affordable handsets these days come with at least a splash-resistant coating that protects the phone from water. However, you can try an experiment. Put any waste or punctured battery in a cheap smartphone and let the water in. This can cause a lot of damage to your phone. In such a situation, if the phone's battery is bad, then water can cause your phone to explode.

8. User error
There have also been incidents of explosions in smartphones due to the mistakes of many users. A similar incident happened sometime back with the Realme 5, which reportedly exploded when the user was riding his bike. The company claimed in the test that this blast happened due to external force being applied to the phone. This punctured the battery and damaged the motherboard. In such a situation, do not let any kind of problem come in the components of the phone. If this happens then go straight to the service center.
