Shopping outside, the power of the phone suddenly showed less than 20%, and could only find a charging treasure everywhere; the video was stubborn, but it was prompted to charge it immediately ... The scene of this scene accompanied by the deepening of people's deepening of mobile phones and became modern. The normal state in people's life. It is also found that the battery health of old phones is always not as good as new mobile phones. So, how can we maintain a "long standby" mobile phone battery?

Factors affecting mobile phone charging

We all know that the charger is used to charge the mobile phone. The charger consists of a charging head and a data cable. The charging head is the output of the current. In order to protect the charging security, there is a power management chip (charging protocol) on the mobile phone to support and recognize it to select the appropriate current and voltage for charging. Observe the charging head, which is marked with current and voltage output data. For example, 5V/2A indicates that the maximum load current of the interface is 2A. When the charger voltage is 5V, the power charging power is 10W. If the charging head of the mobile phone is broken, we need to check whether the charging head is compatible with the mobile phone charging protocol when choosing other chargers.

Partial charger protocol

The charging time of the mobile phone is closely related to the charging power. When the output current and voltage change, the power will change accordingly. In recent years, the technology of lithium -ion battery fast charging technology can increase the power to 100%in a short time. Capital technology needs to be adapted to fast charger and fast charge protocol. The mainstream fast charge protocols include SCP protocols, QC3.0 protocols, VOOC flash charging protocols, MTK PE protocols, etc., which greatly improves charging power. Before turning on the fast charging, the mobile phone needs to match the fast charger, and the matching is successful to turn on the fast charge charging function, otherwise it only supports ordinary slow charging. Ordinary charging technology can only be over 25%of the electricity for 30 minutes, while at the same time, fast charging technology can be up to 60%to 80%of the power.

Are you still charging your mobile phone all night? These behaviors are shortening battery life

In our lives, we often see such news, charger fire or battery explosion causes fire. This accident mostly appears when people are asleep. Usually, our charging is safe. First of all, most mobile phones are currently using lithium batteries. It will "randomly respond". When short -circuit or excessive charging occurs, the lithium battery will automatically cut off the battery circuit; when the internal pressure of the battery is too high, it can trigger the exhaust reduction and reduce it. The pressure device is decompressed; when the battery temperature is too high, the hot -melt protection device will be triggered to stop the electrochemical reaction. Secondly, after the battery is full, the protection function will turn on the protection function to prevent excessive charging, or automatically stop charging, or reduce the charging current to a small range.

Therefore, if the original adapted charger is used, even if it is charged all night, it will not be harmful to the battery. The use of non -original chargers and charging cables may have an irreversible effect on battery performance. Because the mobile phone will identify the charging cable and charger model through the charging protocol, the appropriate current will be charged. If it is not adapted, the actual charging current is a default value. This value is related to the output specifications of the charger and the specifications of the charging cable. When the default current value is not suitable for charging mobile phone batteries, it will be dangerous for a long time.

Someone had done such a set of comparison experiments, using three different brands of mobile phone chargers and charging cables to charge. It was found that when small current chargers charged large -current mobile phones, the speed was slow and charged in the load state for a long time. The device will have an overheating situation, speeding up the loss of battery capacity, and even causing fire or explosion.

While charging, playing mobile phones will also accelerate the mobile phone battery "Shouchi". Calling, playing games, watching videos and other activities are large current consumption, which is far greater than the current provided by the charger. While charging, the use of mobile phones is that the battery is quickly switched in two states of charging and discharge. The life of the lithium battery is closely related to the number of charging and discharge cycles. This switch will affect the service life of the battery.

Putting the phone in an environment with too high temperature and too low is also very unfavorable to battery health. The electrode is unstable in the electrolyte. When the charging and discharge behavior occurs, the two electrodes of the battery occur in a chemical reaction, the active substances are consumed, the chemicals of the transition to electrical energy can be reduced, and the battery capacity decreases. Therefore, when the ambient temperature is too high, the chemical reaction of the battery will be accelerated and the "self -discharge" will be accelerated to reduce the battery capacity; the low temperature below zero will also have a negative impact on the battery structure and even permanent damage.

Scientific charging method, learn now

Knowing the unscientific charging method, how do you charge your mobile phone scientifically and effectively.

1. Ensure reasonable power value

When the battery is out of power and the mobile phone is turned off, it is necessary to say no again. When the battery power is completely exhausted, the mobile phone is charged, that is, entering "deep discharge", such behavior is very large to the battery. The battery power ratio is maintained between 65%and 75%, which is more appropriate. If the power ratio of mobile phones is maintained in this range for a long time, the service life of the battery is the longest.

2. Use compliant charging appliances

When charging, it is best to use the mobile phone original loader. If the original ones cannot be used, and the mobile phone needs to be charged, then you must pay attention to whether the output specification of the charger meets the battery requirements, and pay attention Whether the current can adapt to the mobile phone battery.

3. Pay attention to the charging status of the mobile phone

When charging, try to forget the game and video as much as possible to make the mobile phone "beautiful alone". Playing while charging not only reduces the charging efficiency, but also makes the phone fever. Therefore, when charging, you can often feel the body temperature with your hands. Once you find that the temperature of the phone is heating too fast or too high, you can remove the power supply and stop the charging in time.

At the beginning of the phone, insufficient power is not a troublesome problem. One day or one -day charging can meet daily needs. With the emergence of portable mobile electronic products, such as smartphones, new requirements are made on hand batteries. The powerful mobile phone function also brings the rapid consumption of electrical energy, and carrying the charging treasure with you becomes standard. However, don't forget the damage caused by unreasonable charging methods. Reasonable charging and scientific charging can achieve the dual goals of safety and efficiency.
