Let mobile phone safety charge of six note, together to understand

Due to the Samsung Galaxy Note 7 explosion caused by the full recovery of the incident, the phone explosion is undoubtedly the focus of recent users. Then how to use the phone is the most secure, what is the right way to charge it? I believe this is the majority of users would like to know. Then we together to share six mobile phone charging safety precautions, I hope to be useful to everyone.
Let mobile phone safety charge of six note, together to understand
First, anti-aging batteries
Mobile phones and batteries are generally equipped with security settings, among the battery to avoid the anode and cathode copper device intersection is most important, if the phone line short circuit, the battery security device can be blocked in time, but even the battery itself is malfunctioning, May cause an explosion. With the aging of parts and batteries, the risk of accidents also increased, so users should pay attention to whether the battery is swollen, or metal contact surface discoloration and other signs of aging.

The middle part of the mobile phone battery bulge (red frame shows), that is, the problem of battery drum package, the right is not swollen battery.
Second, avoid phone charges while charging
Many people like to charge while charging, it is recommended that you do not do so, call the moment through the current will be larger, frequent battery charge and discharge, leading to long-term lithium battery overload, natural increase in heat. To know the internal lithium battery is composed of organic electrolyte, in the case of high current, high temperature, the organic electrolyte will be electrolysis, resulting in a large number of gases, resulting in increased battery internal pressure will seriously break the shell (commonly known as " "), Leading to external short-circuit combustion or even explosion. Therefore, we should first pull the phone line charge, even if the unfortunate explosion, it will not hurt themselves. In addition, to develop the habit of using the right hand call, because the left hand close to the heart than the right hand, left hand phone when the leakage will increase the risk of casualties.
Third, reduce the computer charging
I believe we all tried to connect the phone to the computer charging, in fact, doing more harm than good, the phone standby but the computer continues to operate, the latter from time to time to read and write mobile phone storage devices and USB ports, USB power output will cause great fluctuations , Reduce battery life. In addition, USB specification fixed voltage of 5V, current 500mA, but with the increase in cell phone battery capacity, many of the current mobile phone charger rated current of 1,000mA or more than 2,000mA, so the computer USB charging, charging time is not only significantly extended, The computer USB interface will be a long time in an overload state, heat increases, the computer and mobile phone components damage.
Fourth, to avoid alternating use
Do not charge the computer, the original charger to use what will happen? Basically, the use of high current output of the USB charger to charge the electronic device, the problem is not large, if the device needs more than the current provided by the charger, such as 2,000mA input phone, but connected only 200 to 300mA USB Charger, then the charger will be overworked, the phone's internal protection lines, more likely because the current readings do not match automatically cut off power supply, resulting in 99% of the phone charge to stop or broken. Therefore, to use the phone charger to match the charger do not casually with other equipment charger.
Fifth, do not self-short circuit
Charging line quality will also affect the safety, if the metal part of the exposed, the current is less than the phone has leakage, while the user contacts the ground, will form a complete circuit lead to electric shock, so if the wire is damaged, it must be replaced immediately. In fact, iphone or Samsung and other mobile phones in the device and the wire side of the specific signal pin, add the voltage divider resistor to identify the type of device, as long as the original factory foot line, you can fast charge, no risk.
As for how to choose a good charging line, most of the wire is not marked specifications, in addition to price, the simplest way is to use the thickness to identify thicker wire wrapped in insulated rubber and ground isolation of a higher chance of security than Protection!
6, the use of original accessories
General original charger with a transformer, safety protection circuit and comply with Safety Mark and other safety regulations, to ensure that the excessive charge and discharge and short circuit automatically cut off the battery circuit, the higher the security. On the contrary, poor quality chargers, especially low-cost knockoffs, because of cost problems will use defective internal parts, which lack of circuit protection, charging current can not guarantee stability, easy to burn the battery, or even the risk of explosion. In addition, USB standard voltage is 5V +/- 0.25V (4.75V ~ 5.25V), some poor charger output is up to 5.25V or more, it is easy to charge the phone bad. Want to reduce the accident, as far as possible with the regular manufacturers of qualified products for charging.

These six considerations for the user better and more secure use of mobile phones, is undoubtedly very helpful. Therefore, it is recommended that users follow suit!
