Honor 20 Pro Is There Wireless Charging

Over the past few years, the Chinese company Huawei, engaged in the production of telecommunications and network equipment, as well as the release of mobile gadgets, has taken a significant step forward in the development of modern technologies. She was one of the first in the world market to start developing and supplying devices and accessories that have a wireless charging function.

Porsche Design Mate RS was the first smartphone from Huawei, capable of charging wirelessly according to the Qi standard. Its release took place in 2018. In March 2019, the new flagship of the company. Huawei P30 Pro. There are currently 6 models on this market that support Qi.

Wireless charging: what is it?

You can already understand from the name itself that to charge the phone, if it meets the technical requirements, you do not need to use a cable and power adapter. Simply put it on a special mat or other similar accessory (for example, a power bank or another phone), and the battery will begin to charge with energy. Today, mobile devices from many leading manufacturers, not only Huawei, support the BZ function.

What is required for this

Two things are required. The first is a smartphone that supports BZ. If this option is not supported, you can put on a cover in which the necessary module is built-in.

The second thing is a wireless charger. It can be compact stands in the form of a “washer” or rugs. Their shapes and sizes are very different. Some are large and look like mouse pads. There are also small drives built into furniture (tables, for example). The cost of such accessories is very different. start at 10 on average.

Work speed

Many fans of new technologies will be disappointed here. In most cases, wireless charging takes much longer than the usual charging of a smartphone using a USB cable.

However, among the knowledge base there are those that work faster than others. It’s all about power: when it is large, the wireless charger can fully charge a phone with a high-capacity battery in about two hours. Speaking in numbers, the power of the new type of charger should be 5 watts or 10 watts. According to the output current, this will be 5 V wireless charging for a phone with a battery rated for 1 A. This is quite comparable to the traditional 1 A USB charging kit for USB. This charger is equipped with, for example, iPhone 7.

What is the Qi standard?

KB technology is represented by several competing standards. All of them are designed for mobile electronics, primarily for phones.

Most devices support the Qi standard created by the Wireless Power Consortium, as well as the PMA or AirFuel Alliance standards. This means that when you purchase a phone that supports, for example, the Qi standard, you will need to purchase a charger of the same standard, because it is not compatible with another.

In general, the most popular at the moment is the Qi wireless charging standard. It is used in Huawei phones and in flagships of other brands.

How Qi Wireless Charging Works

BZ is carried out by the principle of electromagnetic induction. Energy is transferred from the charger to the receiver located on the back of the phone. The wireless charger uses an induction coil to generate an alternating electromagnetic field. This field, the receiving coil located in the phone, again converts to electricity and supplies to the battery.

As a rule, the transmitting and receiving coils should be in close proximity to each other. In addition, they must be correctly positioned, that is, aligned with each other. Although there are no special requirements for the orientation of the phone.

Most of us are already familiar with inductive charging. It has been widely used since the 1990s in cordless toothbrushes and other compact household appliances.

How to use Qi charging

Huawei mobile phones, namely the models in the above list, have a built-in Qi standard and are compatible with wireless chargers, which also have a “Qi” icon. It may be the Huawei CP60. In order to charge your smartphone on such a station, you just need to put it on the pad. Charging will start automatically.

Aircharge is a wireless standard that differs from Qi. In many cities in the UK and Finland, Aircharge Orb stations are installed in public places. So far, this is the first and only certified multi-head MFi adapter in the world.

All that is required when charging is to connect the phone to the appropriate Orb connector, and then place it on the Aircharge charger. The process will begin instantly. At such a station, phones that do not support the Aircharge standard can be charged using adapters (remote controls for charging from the battery or micro-USB receivers).

Is the phone warming up?

Yes, most phones, like some chargers, slightly heat up from the back panel, where wireless power transmission is directly carried out. But you need to keep in mind that when charging via cable, most devices heat up slightly. Therefore, in this sense, the difference is small and does not raise any questions. You should check from time to time whether the phone is warming up, because noticeable heating during charging may indicate a problem with the battery.

Are there any disadvantages to wireless charging?

There are undoubtedly disadvantages. The disadvantage is that when using modern technologies and standards, it will not work through metal. This means that most devices that support, say, the Qi standard, have either a plastic or glass back panel, which makes them more fragile. BZ may also not work if the phone has a thick case. Although usually the process goes fine through thin plastic cases, it depends on the phone and the charger.
