Ever since the launch of Lumia 920, nokia’s first qi-enabled wireless charging phone, mobile phone wireless charging has gradually come to our attention.In previous years, samsung’s flagship phone supported this function in mainstream phones. However, it was not until last year when apple applied wireless charging technology to iPhone 8 and iPhone X that the domestic market has seen a mushrooming of phones supporting Qi wireless charging.
Nowadays, there are mainly two attitudes towards wireless charging of mobile phones. Some people think wireless charging is really good, and that wireless charging should be the standard of flagship phones.Others, however, think wireless charging is a gimmick, too flashy to be useful.So is wireless charging a standard feature of the flagship phone?
Current wireless charging technologies all adopt Qi protocol, which adopts the principle of electromagnetic induction. One coil of mobile phone, one coil of charging station, induces the current.
The biggest advantage of wireless charging is that it is convenient to put the wireless charging stand on the table and charge the phone at any time.In this way, the fragmented time in daily work and life will be used for charging, so that the mobile phone is almost always in a state of full power.For example, I usually use my mobile phone very frequently. When I don’t use my mobile phone, I put it on the wireless charging pad to avoid the embarrassment of losing power.
Wireless charging does not require the use of the phone’s interface, which has gradually become a demand of users.In recent years, more and more phones have removed the 3.5mm headphone jack, which makes the wired headphone and the phone charging “both impossible”.Wireless charging helps you solve this problem. You can also listen to music through headphones while charging.
Another advantage is that it is cooler. Compared to the charging hole that needs to be aligned with the charging line of the phone, which needs to be plugged and unplugged repeatedly when it is used at any time, the experience of charging when it is put on and using when it is picked up is simply not cool anymore.There is no need to repeatedly plug the charging cable and avoid damage to the tail plug of the phone.
Some people like it, some people don’t like it, some people think that wireless charging is a chicken ribs.First of all, wireless charging, but the wireless charging pad needs to be wired, and the phone also needs to be placed on the charging pad, or is the same as a chain attached to the socket, so there is no difference between wireless and wired.
And wireless charging is really slow. Most of the common charging pads on the market currently support 5W charging power, which is exactly the same as apple’s 5W charging head.Even the fast charging wireless charging pad is at the level of 7.5w or 10W, which is quite different from the mainstream 18W cable quick charging technology in the market.
And the wireless charging pad requires you to buy it yourself, and it’s not easy to carry around. It usually requires one at home and one at work.Better wireless charging pads are usually expensive, like apple’s (but not yet available) charging pad, which can cost as little as ￥1, 000.
The above mentioned advantages and disadvantages of wireless charging are very prominent, so is it necessary for wireless charging to become the standard for flagship devices?First, objectively speaking, more and more flagship phones adopt wireless charging technology, which proves that wireless charging is a trend of mobile phone development. It is likely that the top flagship we have seen in the past year or two will have wireless charging.
In addition, the current disadvantages of wireless charging can be avoided through technological innovation.According to the report, some companies have implemented the wireless charging technology of magnetic resonance, which features the wireless charging within half a meter, and the charging power can be greatly improved, which will be used on mobile phones in the near future.
In addition, wireless charging may become a bonus on flagship phones like the NFC and other technologies, both of which are “redundant features” for some people and essential efficiency tools for others.At least for now, wireless charging, while still immature, has become an important differentiator in our ratings of a phone, and will be supported by a growing number of flagship phones and even high-end products.
