What are the advantages and disadvantages of wireless charging of mobile phones?

Advantages and disadvantages of wireless charging of mobile phones;

Benefits:

1, lightning cable wear is reduced.

On the other hand, the popularity of iPhone wireless charging will reduce the use of cables. The cable wear will be reduced to almost zero. As long as you plug in the wireless charger AirPower, everything will be fine. Users no longer need to plug and unplug their mobile phones frequently, which reduces the wear between the Lightning cable and the interface.

2, convenient, especially when charging multiple devices.

The biggest advantage of wireless charging is convenience. Wireless charging has little effect on mobile phones, but when all electronic products support wireless charging function, the convenience brought to users is even more interesting. Apple said that the future models of AirPods wireless headphones will use charging boxes that support AirPower, so users only need to put them on the charging board to charge. Apple Pencil stylus is in urgent need of wireless charging function, and its current charging method is simply a joke.

Wireless charging is very suitable for small electronic products. Imagine putting a charging pad in a desk drawer, where users can put the spare battery of iPhone to charge and keep it fully charged when necessary.

In addition, users only need one charging board to charge multiple devices. For example, users don't need to unplug the iPhone when colleagues charge it.

3. Wireless charging helps to improve security.

Using wireless charging technology means that users don't need to connect iPhone with unknown cables, which are the hiding place of all malicious debris. It should be safe to put the iPhone on the charging board-unless a hacker develops a malicious piece that uses wireless charging, but so far such a malicious piece does not exist. After iPhone supports charging boards, we can predict that charging boards will appear in hotels, restaurants and other public places in the near future.

Cult of Mac said that the popularity of wireless charging boards may change our work and lifestyle. When going out, users don't need to carry a huge spare battery with them, just put their mobile phones on the public charging board they see, and they can charge them. The popularity of charging boards may be comparable to that of free WiFi.

Disadvantages:

1, wireless charging causes environmental hazards.

Let's discuss the disadvantages of wireless charging function first, because it is very important. The wireless charging board is inefficient. Depending on the design and the location of the user's mobile phone on the charging board, the charging efficiency may be between 30% and 80%. In other words, even in an ideal state, 20% of electricity will be wasted. Although the charging efficiency is constantly improving, the efficiency of low-power charging (such as mobile phone) is lower than that of high-power charging (such as electric car)-the efficiency is close to wired charging.

For every device, charging efficiency may not be a big problem. However, Apple sells 10 iPhone every second, which means that wireless charging boards will soon become popular, and the number will be tens of millions in the next few years, which is a huge waste of electricity. This is bad news for the global ecological environment and climate change.

Phil schiller, Apple's senior vice president of global marketing, announced at the new iPhone product launch conference on 20 17 that Apple was working hard to "make the wireless charging experience better", but did not mention the charging efficiency. Schiller focuses on the ability to charge several devices at the same time on the same charging board, so that the charging board can communicate with the iPhone and display the power on the lock screen. Charging efficiency is undoubtedly the top priority, so Apple may promote the improvement of wireless charging efficiency in the entire mobile phone industry.

2, can't move

Cult of Mac said that another disadvantage of wireless charging is that it is much more difficult to use a mobile phone when charging. With wired charging, users can move their mobile phones while charging-although limited by the length of the cable. When using wireless charging technology, the mobile phone must be placed on the charging board. If the user only plays music when charging the mobile phone, there is no problem, but it is very painful to let the mobile phone complete other functions. Because you can't pick up your mobile phone and enter text, it's difficult to send text messages.
