Wireless chargers will not damage your phone. This is because of how wireless chargers work. Different from traditional chargers, this type of charger uses electromagnetic induction technology, which uses the magnetic field directly generated by the coil to transmit the power. It can transfer the current from the wireless charging plate to the mobile phone battery. For mobile phone batteries In terms of charging, there is not much difference between this charging method and ordinary wired charger charging.

Features of wireless charger:

Theoretically speaking, wireless charging technology is harmless to the safety of the human body. The resonance principle used in wireless charging is magnetic field resonance, which is only transmitted between coils that resonate at the same frequency, while other devices cannot accept the band. In addition, the wireless charging technology uses The magnetic field itself is harmless to the human body.

But wireless charging technology is a new type of charging technology after all. Taking the wireless charger of Maiyuan Technology as an example, many people will worry that wireless charging technology will be the same as when Wi-Fi and mobile phone antenna poles first appeared. In fact, the technology itself is harmless. . Wireless charging technology uses magnetic resonance to transfer power in electric and magnetic fields between the charger and the device, and coils and capacitors create resonance between the charger and the device.

Precautions for using wireless charger:

Do not charge for too long for the first time

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


In the battery safety test experiment, it will continue to charge for 7 hours when it is fully charged, and the output voltage will increase to 1.06 times the standard voltage. In addition, the battery itself also has a protection circuit, so it will not cause danger or explode. But if you use low-quality batteries, it’s hard to say.

Wear a case while charging your phone

In order to protect the mobile phone that we can’t live without, many people choose to wear a case for the mobile phone. But everyone does not know that lithium batteries are very afraid of heat, and they will generate heat when charging, so it is best to remove the mobile phone case to charge.

Nowadays, there are more and more smart things, and mobile phones also have wireless chargers, so will using wireless chargers hurt mobile phones?

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 power conversion rate of wireless chargers is still very high, which saves more energy consumption.

The wireless charger does not harm the mobile phone. The wireless charger uses electromagnetic induction technology, which transmits energy by using the magnetic field generated between the coils. It couples the current from the charging plate to the mobile phone battery. For the battery, it The charging process is no different from that of ordinary wired chargers.

In short, the technology of wireless charging equipment can be widely used in the future. After all, it does no harm to electronic products such as mobile phones, so there is no need to worry that wireless charging will harm mobile phones.

Wireless charging of mobile phones can help users reduce the shackles caused by wired chargers, and it also improves safety. However, this is a new technology, so some friends are worried about whether using wireless charging will damage mobile phones. Will charging speed up the battery loss of the mobile phone?

Does wireless charging hurt your phone?

Under normal circumstances, the wireless charger will not harm the mobile phone. The current working frequency of wireless charging is below 1M, so it will not affect the signal of the mobile phone.

At present, most mobile phones on the market conform to the QI wireless charging standard, and have a built-in wireless receiver. It has a rated voltage and current, so wireless chargers have no effect on mobile phones.

Is it harmful to mobile phone batteries?

Wireless chargers will not harm mobile phone batteries. On the contrary, wireless chargers not only reduce the use of data lines, but also make charging methods more free and safer.

It is basically the same as wired charging, but the rate is lower, but the power conversion rate of the wireless charger is still very high, which saves energy consumption even more.

How to use wireless charger

Using a wireless charger is as simple as placing your phone gently on the wireless charging pad and positioning it.

However, it should be noted that when purchasing a wireless charger, pay attention to your mobile phone model. You should choose a wireless charging panel according to your mobile phone model. If you choose the right model, you can use it directly. The method of use is quite simple and convenient.

Most of the working frequency of wireless charging is below 1M. Most of the mobile phones conform to the QI wireless charging standard and have a built-in wireless receiver. It has a rated voltage and current, so the wireless charger has no effect on the mobile phone. .

Introduction to wireless charger

A wireless charger refers to a charger that does not need to be connected to a terminal device that needs to be charged using a traditional charging power cord. It uses wireless charging technology to transmit electric energy by using the alternating magnetic field generated between the coils. Inductive coupling technology will become a connection A bridge for charging base stations and devices.

The Origin of Wireless Chargers

In the 1830s, Michael Faraday discovered that changes in the surrounding magnetic field would generate an electric current in a wire, and in the 1890s, the Serbian-born scientist Nikola Tesla applied for one of the original patents.

The principle of wireless charger

The wireless charger is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By placing a coil at the sending and receiving ends, the coil at the sending end sends an electromagnetic signal to the outside under the action of electricity, and the coil at the receiving end receives the electromagnetic signal. Signal and convert the electromagnetic signal into electric current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special power supply method. It does not need a power line, relies on electromagnetic wave propagation, and then converts electromagnetic wave energy into electrical energy, and finally realizes wireless charging.

How Wireless Chargers Work

Electromagnetic induction

Using the principle of electromagnetic induction, the current is generated through the electromagnetic induction between the primary and secondary coils, so as to realize the transmission of energy in a spatial range. This implementation of wireless chargers has been promoted by the Wireless Charging Alliance.

radio waves

Radio waves are a relatively mature wireless charging method for wireless chargers. Its working principle is to use micro-efficient receiving circuits to capture radio waves in space, and then convert electromagnetic energy into stable electrical energy.

Is Wireless Charging Harmful to Phone Batteries?

The answer is no, wireless charging technology is not a new technology, just because the loss in the charging process is large, the applicable field is small, and the popularity is not high, but with the emergence of smart phones, wireless charging technology has been applied to mobile phones Field, its principle is to use electromagnetic induction to convert electrical energy into special energy, and then transfer it between magnetic fields. The transfer method and technology are not important, what is important is that it can charge mobile phones. Aside from being slightly less efficient, it doesn’t require the use of a data cable, there’s not much difference, and it won’t do any damage to the phone’s battery.

Overview of the principle of mobile phone wireless charging

I won’t talk about technical terms. Let’s describe its principle in plain language. We can regard the wireless charger as an energy conversion device. When the user plugs the wireless charger into the socket, the other end is plugged into the mobile phone. (some mobile phones have their own wireless charging device), as long as the wireless charger keeps a constant distance from the mobile phone, and there is no particularly serious interference around, the current provided by the charger will be converted into energy (electromagnetic waves), and the energy will be The charging receiver plugged into the end of the mobile phone or the mobile phone (with a built-in energy conversion device) receives it, then converts it into current, and then supplies it to the battery for charging. Although the charging efficiency is lower than that of wired charging, it can be used in a constant environment. Continuously charge the phone battery.

Why is it said that wireless charging will not cause damage to mobile phone batteries?

Most of the batteries of smartphones are lithium batteries, and there are many factors that lead to the decline of battery life, which are affected by battery quality, technology, structure, charging voltage, charging current, use environment, use frequency, etc., but under normal circumstances, mobile phones The service life of the battery will continue to decrease as the user’s normal use of the mobile phone increases. Taking charging and discharging as an example, the service life of most lithium batteries (full charge and discharge times) is about 300 to 600 times, while wireless charging technology only changes If the charging method is changed, it will not affect the battery itself. It just converts wired charging into wireless charging. As long as the wireless charging device can provide stable and matching voltage and current, it will not cause damage to the battery.
