Do you know what are the misunderstandings of mobile phone battery usage?

1. Recharging the mobile phone after the battery is exhausted Affected by the use of Ni-MH batteries, many people still like to charge the mobile phone battery after it is completely used up. Regarding lithium-ion batteries, this does not serve the purpose of preventing the memory effect, and the activity of lithium-ion elements is insufficient when the battery is used up and then recharged, which will affect the battery capacity for a long time. 2. The mobile phone battery should be fully charged (or emptied) if it is not used for a long time. Many people have multiple mobile phones or batteries in their homes. Some batteries will be left unused for a long time. Many people use two extreme methods to fully charge or empty. Electricity. In fact, these two methods will affect the life of the phone. The correct way is to charge the 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 use lithium-ion batteries. Unlike the previous nickel-hydrogen batteries, lithium-ion batteries do not have a memory effect (to be correct, the memory effect is very weak), and there is no activation one. That said, long-term charging will cause certain damage to the battery. So how long should the first charging time be controlled? This depends on the battery capacity. Generally speaking, it takes 2 to 4 hours. After the mobile phone shows that the charging is complete, it can be charged for another half an hour. 4. Overcharging will cause the battery to explode. Lithium-ion batteries generally have safety protection circuits and a variety of safety devices to ensure that the circuit of the battery is automatically cut off during overcharge and discharge and short-circuit; excessive internal pressure of the battery will also trigger the decompression of the exhaust device ; If the battery temperature is too high, the hot melt protection device will be triggered to stop the electrochemical reaction of the battery. Therefore, unless there is a quality problem, the battery will not explode due to being plugged in for a long time. However, if the battery is not unplugged after being 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 the phone is charging will cause an explosion. Lu Jianguo said that this argument is untenable. If such a danger really exists, the product will set up a procedure that does not connect to the phone when charging. However, from a health point of view, the wire will limit the user's range of activities, and making calls while charging may cause the user to stay in one place for a long time, causing excessive muscle tension. Therefore, it is best to unplug the power before talking. When charging, do not cover anything on the battery or put it on the bed to avoid fire. 5. Using universal chargers Many people like to use universal chargers. They think that universal charging is cheap and convenient. However, this kind of charger is not manufactured by the original factory, and its charging current is not suitable for all battery models, and the charger itself is of poor quality. There have been many explosions. 6. Put the phone in the sun to warm the phone. Many old models of mobile phones show that the battery power is lower 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 phone in the sun. , Or put it next to the heater to keep warm. This approach is also wrong. Once the battery is overheated, it can easily cause an explosion. 7. The battery of the mobile phone can be restored by freezing it in the freezer of the refrigerator for three days. There are rumors on the Internet that the old battery of the mobile phone can be restored by freezing in the refrigerator for three days. Many netizens have tried it and the results are really effective. In fact, this approach is also undesirable. The humidity in the freezer compartment of the refrigerator is high. Once the mobile phone battery gets damp, it is extremely dangerous during use. Experts say that if the mobile phone battery is not used for a period of time, the power will be partially restored when it is 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 repeated use. And seriously affect battery life. . 8. The battery can no longer be used when the battery reaches the limit of charging times. Manufacturers generally mark the battery usage limit in the mobile phone manual, while consumers calculate the battery life based on the number of times. In fact, the battery life depends on use, storage, and charging. There is no fixed value for many factors. Nine, do not pay attention to battery cleaning. Among mobile phone users, few people pay attention to the cleaning of the battery. In fact, occasionally wipe the metal contact surface of the battery with an eraser to remove the rusty material on the metal surface, which is helpful for the charging and charging of the battery. Extend battery life. 10. Mobile phones u003d game consoles. Some young people like gaming mobile phones, holding a mobile phone to play wherever they go. 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. explosion occurs. 11. The battery shows that it is full, but the phone will automatically shut down after a while. Most of the battery charging is abnormal, and it is normal to use the universal charging for eight hours before using it.
