With the continuous advancement of science and technology and people's demand for convenience, a variety of household devices have begun to support wireless charging, and wireless charging can be said to have become completely popular. Some people can't put it down for wireless charging, but some people are questioning it in various ways, will long-term use of wireless chargers damage the battery? Is it true that wireless fast charging will reduce battery life? Today we're going to answer it.
Let's start with the conclusion: the impact on the battery makes no difference.
In detail, the principle of wireless charging is actually very simple, and I believe many people know the phenomenon of "electromagnetic induction". It is a magnetic field generated by the current after passing through the coil, which is conducted by the wireless charging device to the charging terminal equipment, and the terminal equipment converts the received energy into electrical energy and stores it in the battery of the device. Current wireless chargers use this principle.
So will the magnetic field generated by wireless charging damage the battery of electronic devices? The answer is no. Because the back of the mobile phone that supports wireless charging will also have a coil, which is used to receive and collect magnetic field energy, the electromagnetic induction of wireless charging can only affect the coil on the back of the mobile phone.
The various principles are too complex and difficult to understand, and we use practical cases to answer this problem. Taking the test mobile phone used by Fuying engineers as an example, they have been using a wireless charger for charging for the past six months, and the final battery loss is about 3.8%; Compared with the same frequency of use, the battery loss of charging a mobile phone with a wired charger is also about 3.9%. So, whether it's wired or wireless, the loss on the phone's battery is almost the same.
If you encounter a wireless charger that damages the battery, you may wonder about the following possibilities:
1. Whether your own wireless charger is an unqualified charger, because only a charger that will be unqualified will be more likely to cause battery production attenuation problems.
2. Wrong charging habits, most of the smart electronic products use lithium batteries, of which lithium ions have a certain activity, if it is said that excessive discharge, it will definitely affect the battery life.
