Wireless charging and fast charging which harm the battery

1, in theory, although compared with the traditional slow charging is different, but the two ways have a specific charging device and the supporting battery, so charging will not damage the battery. If you do not believe that you can go to see some of the online evaluation of fast charge and unlimited charging videos, it is enough to prove that the two ways will not affect the normal life of the mobile phone. 2, in theory, wireless fast charge and mobile phone fast charge, are designed for mobile phones, mobile phone battery is not any harmThere is still something to be understood about this. However, when the user chooses a wireless charger, it is best to choose a charger that is compatible with the mobile phone, or choose a charger produced by a regular manufacturer.

3, see the introduction of wireless charging to understand its working principle. It is generally believed that fast charging because of large current and high heat, so the loss caused by relatively slow charging to the battery will be larger, there is a comparative analysis on the Internet, the actual impact is quite small. Bad will not be bad, that is, two together have a little impact on battery life, if you can try to use line charging, wireless is just more convenient, on maintenance, mobile phones prefer line charging.

Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, and uses the latest wireless charging technology to transmit electric energy magically by using the magnetic field generated between the coilsInductive coupling technology will become a bridge connecting charging base stations and equipment.

The principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.

Wireless charging technology is a special way of power supply, it does not need the power line, relying on the propagation of electromagnetic waves, the electromagnetic wave energy into electricity, and finally achieve wireless charging.Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode.

How to use Huawei Mate10 wireless charging

Plug in the wireless charger, put the phone on the top, wireless charging is very chicken in fact, although the phone does not need to plug, but must be used within a certain range.

Go to the Settings screen of your phone and find "Wireless charging" or similar in the "System and Update" or "Battery" optionsThe option of... The exact menu name and location may vary depending on the Huawei phone model, but a switch is usually provided to enable or disable the wireless charging feature.

Huawei mate10 mobile phone does not support wireless charging. Huawei Mate 10 is equipped with a 9-inch 2560*1440 RGBW HDR display (16:9), Mate 10 Pro uses a 6-inch resolution of 2160*1080 OLED full screen (18:9), in the case of the same width of the phone can also enjoy a larger screen experience, in addition to IP67 protectionSplash resistance rating (IP53 for Mate 10).

First, click on [Settings] on the desktop of your phone. Next, under the Settings menu, find and click on [Battery]. Finally, open the switch button on the right side of [wireless reverse charging]. Huawei radio charging only for some mobile phones have this function, not all mobile phones have. Huawei Wireless charging method: Connect the charging head to the charging base using a data cable, and then plug the charging head into the power supply.

The Huawei mate30 is used as an example. To enable wireless charging, click [Settings] on the desktop of the mobile phoneSet]. Under the Settings menu, find and click on [Battery]. Turn on the switch button on the right side of [Wireless reverse charging]. The Huawei Mate30Pro, a smartphone owned by Huawei, was unveiled in Munich, Germany, on September 19, 2019.
