The phone battery swells when charging

Causes of battery heating and expansion:

The power consumption of the mobile phone in standby is very small, that is to say, the equivalent load resistance of its battery is large, so the discharge current is very small, so the battery will not heat up, and the internal consumption of battery power is very small.

The power consumption of the mobile phone when waiting for calls or games is very large, that is to say, the equivalent load resistance of its battery is small, and it is discharged with a high current when working. After the battery discharges a part of the electricity, the internal resistance increases, but the current required for the work of the mobile phone cannot be reduced, so a considerable part of the energy is consumed on the internal resistance of the battery, resulting in the battery heating, the discharge acceleration, and the battery use time is quickly shortened.

The above is the reason why the mobile phone battery will heat up when used for a long time.

Dangers of mobile phone battery heating:

1.The battery of the mobile phone will heat up for a long time, which will cause the internal parts of the phone to heat up, so that the phone will restart or.

Hang up the ** in the call.

2.If the mobile phone battery is heated for a long time, the heat of the battery itself will increase, if it is sealed (nokia and the like are not sealed, the battery is directly loaded into) the battery will make its internal air expand violently, resulting in the battery like an external protrusion, which will seriously make the battery**.

3.Prolonged heating of the mobile phone battery will accelerate the aging process of the mobile phone itself and shorten its lifespan.

The above is the harm of mobile phone battery heating for a long time to mobile phones.

Mobile phone battery heating prevention and solutions:

One. Prevention method:

1.It is normal for the phone to generate no more than 60 at normal room temperature, and the battery will not be damaged.

2.It is not advisable to use a high-current charger for too long, as charging for too long will damage the battery and generate heat.

3.It is best to use the charger in an original or quality reputable product.

4.If you are not in a hurry to use it, it is recommended to charge it with a base charger (slow charging mode) to avoid heating the battery.

5.If you feel that the phone is a little hot when using the phone or the battery is charging, you can use * to check its temperature, if it exceeds 60, immediately return to the standby state or change the battery, and unplug the charger immediately if it is charging.

Two. Workaround:

1.If the mobile phone battery has been charged and bulging, there is also a way to solve it. It is to use your fingers to find the gap of the battery first (the back of the mobile phone battery is close to the charging electrode of the mobile phone, and it is a little soft when pressed), and poke a small hole with the target to let the air inside run out.

2.Buy an additional battery.

Take your pick. It is recommended to change, because there are so many ** cases.

Huh: Satisfied?

It is the reason for the long period of use.

It's too long, and there's the tide.

Near-end-of-life, the cause of this is usually due to overcharging.

It has a lot to do with the charger.

The reasons for the swelling of the mobile phone battery are:

1. Most of the mobile phone batteries use high-energy lithium batteries. Generally, this kind of battery will bulge and swell after use. It is very dangerous to continue to use this phenomenon, so once this situation occurs, the battery should be replaced in time, and it cannot be continued to be used, so as to avoid the occurrence of mobile phone ** incident.

2. Generally speaking, the battery of mobile phones will reach the limit of service life after one or two years of use. The mobile phone battery cannot be used for a long time, at most three years, and after one or two years, the mobile phone battery will have various problems. The main causes of these problems are the quality of the battery and the overuse of the battery.

3. Lithium battery is a kind of metal battery, which is easy to expand and fry after being exposed to air for a long time. Lithium batteries are also a metal that can be charged and discharged, so it will react chemically with oxygen and is relatively undurable.

If the phone battery is swollen, then the battery should not be used. Because he still has a certain danger. It is recommended to replace the battery with a new one.

It is very dangerous for the battery of a mobile phone to swell, and it may explode when you use it one day. In this case, it is better to quickly go to the manufacturer's after-sales service outlets or third-party mobile phone repair institutions to replace the battery.
