How a smartphone battery explodes and how you can prevent it

From time to time, reports appear of exploding smartphone batteries. Recently, there have been reports of Xiaomi and OnePlus phones exploding. So how do phone batteries explode and what can a smartphone owner do to prevent such accidents? Let’s find out.

What causes the explosion of smartphones?

Most of the time, the smartphone explodes due to a problem with its battery. Nowadays, smartphones are equipped with lithium-ion batteries. These batteries have a balance of positive and negative electrodes that allow them to recharge. In some cases, battery failure components lead to a volatile reaction.

If these situations are not handled properly, the reactions can eventually lead to explosions.

What harms phone batteries?

While there are many factors that contribute to battery damage, the most common one is overheating. If a charged battery or an overburdened processor becomes too hot too quickly, it can damage the chemical makeup of the phone battery and can trigger a chain reaction called thermal runaway. This process causes the battery to generate more heat, which eventually causes a fire to catch or explode.

Other reasons for phone damage

Aside from excessive heat, physical damage caused by falling or excessive bending can also damage the integrity of the battery. However, other factors that can contribute to overheating are leaving the phone in the sun for too long, CPU malware, and charging destruction.

There can also be some damages that are out of users’ control, such as devices used for many years and the internal components of the battery can wear out. This eventually causes the smartphone battery to swell and overheat.

Otherwise, there can be production issues from the manufacturer.

Things to look out for to prevent excessive damage from explosion

While phones give no specific warning before they explode, there can be some hissing or popping sounds, or the smell of burning plastic or chemicals. These indications should be noted as being on the alert that the phone may be damaged and may explode.

Users should also note if the device gets too hot, or when the battery is swollen, which can result in a protruding screen, enlarged notch, or a swollen chassis. In such cases, the user should immediately turn off his phone and take him to the service as soon as possible.

How to prevent phones from exploding?

In many cases, the user cannot prevent phones from exploding, such as when there is a manufacturing defect or the power supply deteriorates naturally.

However, in other scenarios, there are certain steps a smartphone user can take to prevent damage that could lead to an explosion.

  1. Use a phone case to avoid physical damage to the device;
  2. avoid extreme outdoor temperatures;
  3. Maintain good battery hygiene (charge your phone between 30-80 percent of its battery life);
  4. Use of cables and charges recommended by the company;
  5. Keep the phone safe from malware that can damage the battery.
