With the application of wireless charging technology in the field of mobile phones, many users worry that wireless charging will cause damage to mobile phone batteries. Let’s see what authorities say?
Does wireless charging damage your phone’s battery?
The answer is no, wireless charging technology is not an emerging technology, just because of the large loss in the charging process, the application field is small, and the popularity is not high, but with the emergence of smartphones, wireless charging technology has been applied to mobile phones. The principle is to use electromagnetic induction to convert electrical energy into special energy, and then transfer it between the magnetic fields. The method and technology of the transfer are not important, the important thing is that it can charge the mobile phone. Compared with the traditional charging method, in addition to charging Apart from being slightly less efficient, it doesn’t require the use of a data cable, other than that it doesn’t make much of a difference, and it doesn’t damage your phone’s battery.
An overview of the principle of wireless charging of mobile phones
We describe the principle in easy-to-understand 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 inserted into the mobile phone (some mobile phones come with wireless charging devices), as long as the wireless charger maintains a constant distance from the mobile phone, and there is no serious interference around, the current provided by the charger will be converted into energy (electromagnetic waves), and this energy will be The charging receiver or mobile phone (already built-in energy conversion device) plugged into the end of the mobile phone receives it, then converts it into current, and then supplies the battery for charging. Although the charging efficiency is lower than that of wired charging, in a constant environment, it can be A steady stream of charging your 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 service life, which are affected by battery quality, technology, structure, charging voltage, charging current, use environment, frequency of use, etc. The service life of the battery will continue to decrease with the increase of the user’s normal use of the mobile phone. Taking charging and discharging as an example, the service life (full charge and discharge times) of most lithium batteries is about 300 to 600 times, while the wireless charging technology only changes The charging method will not affect the battery itself but only convert 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.
What wireless charging technology changes are the charging method. The center of improvement revolves around “wired”. There are many factors that affect the service life of mobile phone batteries, but the only factors related to charging equipment are charging voltage and charging current. As long as the wireless charging equipment can provide stability, and match How can the voltage and current of the mobile phone cause damage to the mobile phone battery?
