This article gives you a talk about the advantages and disadvantages of Apple wireless charging analysis paper, as well as the knowledge points corresponding to the advantages and disadvantages of Apple wireless charging analysis paper, I hope to help you, don't forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1. What is the principle of back-to-back wireless charging of Apple mobile phones?
Wireless charging of Apple mobile phones uses the principle of electromagnetic induction. What is the principle of wireless charging for Apple mobile phones? The principle of wireless charging technology is actually the principle of electromagnetic induction. Who took high school physicsBao, I believe everyone is very clear that electromagnetic waves have energy, can be obtained through the electromagnetic coil, and then the coil will form a current, and finally through the integration of the circuit can be charged.
According to the mobile phone wireless charging method and implementation principle, it is generally classified into three categories, magnetic resonance, electromagnetic induction and radio waves. The most used is electromagnetic induction, compared with the other two wireless charging methods, electromagnetic induction technology is more mature, charging efficiency is higher than other ways. Secondly, its implementation structure is simpler and more stable, so the ones we currently use on our mobile phones areThis kind of electromagnetic induction.
The principle of mobile phone wireless charging is that there are two coils on the charging board and the mobile phone, the coil of the charging board is connected to the power supply, and the following coil is added with alternating current, which will produce a changing magnetic field. When the phone is placed on the charging pad, the coil on the back cover of the phone senses changes in the magnetic field and generates an induced current, which is then converted into direct current, so that the phone battery can be charged.
1, Apple mobile phone general we are using direct chargeIt is better, its charging effect is also a direct point, wireless charging is now a more novel way, but I still accept wired charging is better. I always feel that the money will charge the efficiency of the battery will be higher. The iPhone12 can be charged wirelessly or via wired.
2, apple straight. Direct charge can be charged fast, but also can play at the same time, wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. However, the conversion efficiency is best at about 80%, and the remaining electrical energy can only be converted into heat, so the heat of wireless charging has been a big questionQuestion. High-power wireless chargers also need to be paired with active cooling fans.
3, Apple cable charge well. The advantage of the magnetic magnet is that it can be adsorbated near, and the adsorption can be charged. The charger is automatically aligned with the position of the charging coil, which solves the problem of manual alignment for traditional wireless charging. But it is still a wired form, and the power is not as good as wired charging, so the key moment or wired charging is more realistic. If the MagSafe magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.
1. Apple's wireless charging doesn't hurt cell phone batteries: The iPhone is a series of mobile phones powered by Apple Inc. 's iOS operating system that went on sale on January 9, 2007.
2, iphone wireless charging does not harm the battery. The principle of wireless charging is the built-in wireless charging function in the mobile phone, only need to put the mobile phone on the wireless charger, and wireless charging technology has been very mature, no damage to the battery behavior; Avoid charging while chargingYou can extend battery life by playing with your phone and charging it for too long. Because wireless charging uses the magnetic induction principle to charge the iPhone.
3, Apple wireless charging does not harm the battery. The wireless charging technology of Apple mobile phone uses the principle of magnetic induction, which transmits the current to the charging board and the phone through electromagnetic induction. In this process, the electromagnetic field will generate a small amount of heat to the radio components inside the phone, but this heat is very small and not enough to cause damage to the battery.
4, bad, wireless charging in fact, the battery is still working. Due to wireless charging the battery is charged onePart of the time, it with the phone data in and out, screen alerts, or playing music, the battery is part of the loss. Then the battery is actually working all the time.
5, the unqualified third-party power adapter and data connection line do not have over-voltage and over-current protection, which is easy to cause unstable charging power, resulting in battery damage. The official recommendation is 0 ° C ~35 ° C is the ideal working environment for iPhone, too high or too low temperature will have a certain impact on the phone battery.
6, low charging efficiency: compared with wired charging, wireless charging efficiency is low. This means that users take longer
