2, advantages: non-contact, no wire, mobile. Disadvantages: short distance, small power, poor efficiency. Low efficiency: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency,You need a cable to charge your phone.
Methods to check whether the mobile phone supports wireless charging are as follows: check the mobile phone manual, check the mobile phone Settings, check the mobile phone appearance, official inquiries, third-party applications, etc. In the specification parameters of the manual, there will be a relevant introduction to wireless charging of mobile phones. If the phone supports wireless charging, it will be clearly explained in the manual. View Phone Settings In your phone's Settings, you can find options such as battery or wireless and networking.
One: Test with a wireless charger This is the simplest and most direct way to put the phone in a wireless chargerIf charging is displayed, it means that wireless charging function is available, and vice versa, it is not supported. This test is because the current wireless charging mobile phones and chargers on the market are compatible with the QI protocol, and can be charged immediately.
Incorrect charging position Check whether the phone is facing the center of the wireless charging pad, if not, it may cause failure to charge. If there are obstacles between the charging pad and the phone, such as keys, coins, etc., it will affect the charging effect and they need to be removed. The phone case is too thick thick protective case may affect the charging effect, try to take down the phone case and then charge.
In order to simulate the real use environment, we use Apple iPhone 13Pro and Huawei P50 Pro are used as fixed test machines. During the test, the power of the two mobile phones is first exhausted, and then they are respectively placed on the wireless charging board of the car for 15 minutes to test their charging efficiency. After charging, the back of the two phones was measured with an infrared thermometer to test the heat generated by the body.
Therefore, in the test must consider the charger, interface line and battery three aspects of the match, in order to ensure the accuracy of the charging efficiency. Next, the fast charging efficiency of different mobile phones is evaluated through a test device with a charge control chip. Test equipment will record the battery voltage, current, charging time, charging speed and other key data of each mobile phone, and then comprehensively calculate the charging efficiency of each mobile phone.
Plug the wireless charger into the power supply and check that the wireless charger is working properly. If the wireless charger does not work properly, you can try to replace the charger or check whether the cable of the charger is damaged. Place your iPhone on a wireless charger and watch to see if it starts charging. If the phone does not start charging, you can try adjusting the position of the phone or repositioning the phone. Check whether wireless charging is enabled on your phone.
Slight heat will certainly be there, but the MagSafe wireless charge power is only about 15w. MagSafe A charging connection technology from Apple. The interface has a magnetic device, which absorbs or falls off by itself under external force. How to use MagSafe External battery? The MagSafe external battery can be quickly and safely removed for all MagSafe supported iPhone modelsLine charging, thereby extending the service life of the device.
Apple charging head hot hand is normal, because the Apple computer itself is not good heat, often high temperature. The sizzling current sound may be due to the aging of the parts (check for leakage). There is also a common problem of Apple computers, if it is the magsafe1 or 2 generation of the female magnetic head may stick some dust or sand to affect the charging joint connection, so try to wipe the magsafe female head with a toothpick against an alcohol-soaked cotton ball, the effect is significant.
This situation is certain, generally speaking, Apple mobile phone cable charging is slow enough, noThe same goes for the thread. And high-power wireless charging is sure to heat up. So it's normal.
