One: Recharge the phone after it runs out of power

Affected by the use of nickel-metal hydride batteries, many people still like to completely exhaust the mobile phone battery before recharging. For lithium batteries, this does not prevent the memory effect, and the lithium element has insufficient activity when the power is used up and then recharged, which will affect the battery capacity for a long time.

Two: The battery of the mobile phone should be fully charged (or vented) when not used for a long time

Many people have multiple mobile phones or multiple batteries in their homes. Some batteries will be left unused for a long time. Many people use two extreme methods-fully charged or empty. In fact, these two methods will affect the life of the mobile phone. The correct method is to charge the mobile phone to 40~60% and store it in a cool and dry place.

3: The first charge takes more than 12 hours

In 2013, mobile phones mostly used lithium batteries. Unlike the previous nickel-metal hydride batteries, lithium batteries do not have a memory effect (correctly speaking, the memory effect is very weak). There is no activation. Long-term charging will cause a certain amount of battery damage. damage. So what is the best time to control the first charge? It depends on the capacity of the battery. Generally speaking, it takes 2 to 4 hours. After the phone shows that the charging is completed, it can be charged for another half an hour.

Four: Overcharge will cause battery explosion

Lithium batteries generally have a safety protection circuit and a variety of safety devices to ensure that the battery circuit is automatically cut off during excessive charge and discharge and short circuit; too high internal pressure of the battery will trigger the exhaust device to decompress; too high battery temperature will trigger heat Fuse protection device, thereby stopping the electrochemical reaction of the battery. Therefore, unless there is a quality problem, the battery will not explode due to prolonged charging. However, if the power is not unplugged after fully charged, the battery will remain fully charged. Although it will not explode, it will speed up the loss of battery capacity.　In addition, there are rumors that answering the phone while charging the phone will cause an explosion. Lu Jianguo said that this statement is untenable. If there is such a danger, the product will set up a program that does not connect to the phone when charging. However, from a health point of view, the electric wire will limit the user's range of activity. When charging and answering a phone call, the user may be fixed in a place for a long time, causing excessive muscle tension, so it is best to unplug the power and talk. Do not cover anything on the battery when charging, or put it on the bed to avoid fire.

Five: Use "Universal Charger"

Many people like to use the "universal charger" and think that the universal charger is cheap and convenient. However, this kind of charger is not produced by the factory, its charging current is not suitable for all battery models, and the quality of the charger itself is poor, causing many explosions. .

Six: "heat" the mobile phone in the sun

Many old models of mobile phones show lower battery power in winter than in other seasons. This is because the cold reduces the chemical reaction activity in the battery, so many people like to put the mobile phone in the sun or by the heater to "heat" . This approach is also wrong, once the battery is overheated, it is easy to cause an explosion.

Seven: Put the mobile phone battery into the refrigerator freezer "freeze" for three days to restore power

There are rumors on the Internet that the old battery of the mobile phone is placed in the refrigerator for three days to restore some of the electricity. Many netizens try to achieve results. In fact, this method is also undesirable. The humidity in the freezer of the refrigerator is high. Once the battery of the mobile phone gets wet, it is extremely dangerous during use. Experts said: “Mobile phone batteries are not used for a period of time, and the power will be partially restored when used again. Freezing in the refrigerator will destroy the internal structure of the battery. Although it will show a short-term increase in power, it will lose its effect after multiple uses. , And seriously affect battery life.".

Eight: The battery can no longer be used after reaching the limit of charging times

Manufacturers generally indicate the number of battery usage limits in the phone manual, and consumers calculate battery life based on the number of times. In fact, battery life depends on many factors such as use, storage, and charging. There is no fixed value.

Nine: Do not pay attention to battery cleaning

Few people pay attention to the cleaning of the battery among mobile phone users. In fact, occasionally wiping the metal contact surface of the battery with an eraser can remove the rusty substance on the metal surface, which helps to charge the battery and extend the battery life.

Ten: mobile phone = game console

Some young people like gaming phones, where to go to play with a mobile phone. However, gaming mobile phones generally have higher chip performance and poor heat dissipation performance. Long-term use will cause the body and battery to overheat and explode.

Eleven: The battery display is full but the phone will power off automatically after a while

In such cases, most of the batteries are abnormally charged. You need to use a universal charge for eight hours and then use it to normal.

Twelve: The battery is dead and the phone cannot be charged after the phone is automatically turned off

This is because the battery is completely used up. You also need to use a universal charger to charge it for a while and then use the direct charge after the battery is charged.
