Does the wireless charger damage the phone? What should I pay attention to when using a wireless charger?

The use of chargers allows many electronic devices to operate normally. Without chargers, our lives will be troubled to a certain extent. In order to enhance everyone's understanding of the charger, this article will introduce the wireless charger related content, mainly to analyze whether the wireless charger is harmful to the mobile phone and explain the precautions of the wireless charger. If you are interested in chargers, you might as well continue reading.

Lithium battery wireless charger

Is the wireless charger harmful to mobile phones?

The wireless charger will not harm the mobile phone under normal circumstances. The current working frequency of wireless charging is below 1M, so it will not affect the signal of the mobile phone. Wireless charging has no effect on the battery life of mobile phones. It is basically the same as wired charging, but the rate is lower, but the conversion rate of wireless chargers is still very high, which saves more energy. Wireless chargers mainly use inductive coupling technology. Because the coupling technology mainly generates current through the magnetic field of the coil, the internal components of the battery cannot form a magnetic field, so the internal structure of the battery will not be damaged during the power-on process. At present, most mobile phones on the market conform to the QI wireless charging standard, with a built-in wireless receiver, which has a rated voltage and current, so the wireless charger has no effect on the mobile phone.

Precautions for using wireless charger

1). Please choose the original or 3C certified product for the charging plug

As an electrical product, it is recommended to use the original plug. First, because it is specially developed for your mobile phone, the charging speed is guaranteed. Second, the safety is guaranteed. In addition, other 3C products with the same parameters as the original plug can also be used with confidence. 3C certified products have requirements for safety from design to production, and safety is guaranteed. Because the use of inferior chargers can cause explosions and hurt people, there are too many things to mention, so I won't say more here.

2). Is the charging cable correct?

The same is true for the charging cable. It is best to use the original charging cable. The core material in the charging cable, the diameter of the wire, and the material of the metal contact piece of the charging interface will all determine the amount of current that can be carried. After anatomy, the diameter of the inferior charging cable is obviously smaller than the national standard value, and there is no insulating protective film inside. If you choose a low-quality charging cable, firstly, the insulation performance is poor, the current carried is small, and the charging speed will slow down, which will seriously damage the battery, and even cause electric shock, fire and other accidents.

3). It should not take too long for the first charge

The first charge does not require anything to be fully charged for 12 hours. This is what the old battery needs to do. The current battery is basically a lithium battery or a polymer lithium battery. The first charge only needs to be charged as usual.

4). Number of charging

There is a saying: each mobile phone battery has a fixed number of recharges. If the number of recharges is too many, it will accelerate the aging and strain of the battery! In fact, this is wrong. The number of recharges of a lithium battery refers to the complete charge and discharge, so it is best to charge as you use it.

5). New mobile phones need to be activated?

The new mobile phone needs to use up all the electricity in the mobile phone before charging, and it needs to be operated repeatedly 3-4 times. This is called activation. This is required for mobile phones in the past, but now lithium batteries are no longer needed.

6). Play while charging

According to technical standards and corporate regulations, the mobile phone should be safe when used in conjunction with the wireless charger. Under normal circumstances, there is no problem in making and receiving calls when charging. However, the market is flooded with many low-quality chargers. Such chargers cannot meet safety requirements and are prone to dangers such as soft breakdown. Therefore, users are reminded not to buy too cheap chargers. It is best to buy 3C certified chargers and look for charging. The safety mark 3C on the device. Therefore, when using Sanwu products, you need to be vigilant while charging and playing with your mobile phone. Inferior chargers are easy to die, and if unexpected problems occur, they may be fatal!

7). Overcharge

In the battery safety test experiment, it will continue to charge for 7 hours when fully charged, and the output voltage will increase to 1.06 times of the standard voltage. In addition, the battery itself has a protection circuit, so it will not cause danger and will not explode. But if you use inferior batteries, it's hard to tell. The explosion of Samsung's mobile phone illustrates this point. Therefore, it is best to unplug the charger in time after fully charged.

8). Do not wear a mobile phone case for charging

In order to protect the mobile phones that we can't do without, many people choose to wear mobile phone covers! But everyone doesn't know that lithium batteries are very heat-resistant and will generate heat when charging, so it is best to take off the phone case and charge.
