Mi 9pro supports wireless charging. How to use wireless charging: On the mobile desktop, drop down the notification bar and select wireless reverse charging; Then click Know in the pop-up prompt box, you can put the charged device in the smallThe meter 9Pro is charged in the center of the back cover. The Mi 9Pro5G is the second 5G smartphone released by Xiaomi on September 24, 2019.
The use method of Mi 9pro wireless charging is: on the mobile phone desktop, drop down the notification bar and select "wireless reverse charging"; Then click "know" in the pop-up prompt box, you can put the charged device in the center of the Mi 9Pro back cover for charging. The screen size of the Mi 9Pro5G version is the same as that of the Mi 9, which is 39 inches; In terms of color matching, Mi 9Pro5G has two colors of dream white and titanium silver black.
How to use Millet 9pro wireless charging? Buy a wireless charger, then connect the charger to a power source. Then place the Mi 9 in the appropriate position of the wireless charger to start charging. Mi 9pro uses a universal charging combination, that is, it supports four charging forms of wired fast charge, wireless flash charge, wired OTG backcharge and wireless backcharge, which can be charged at any time, readily and arbitrarily. The wireless flash charge power can reach 30W.
also supports fast wireless backcharging for other devices that support Qi protocol wireless charging, up to 10W wireless charging power, after pulling down the notification barSelect "Wireless reverse charging", and then click "Know" in the pop-up prompt box, you can put the charged device in the center of the Mi 9 Pro back cover for charging.
When the LED light status is green and blinking, the wireless charger is in the error and protection stage, at this time, you should pay attention to whether there is a metal object placed on the wireless charger, and observe whether it can be used normally after removing it.
First, we need to confirm whether our millet 11 supports wireless charging function. You can view this information in your phone's Settings. Go to "Settings" - "Battery and Performance" - "Wireless charging", such asCheck with the nearby Huawei customer service center.
If you use a Huawei mobile phone and cannot use wireless charging, perform the following steps: 1. Check whether a wired charging device is connected at the same time. If wired charging and wireless charging are used at the same time, wired charging is preferred.
The methods that can be taken in this case are: make sure that the phone is compatible with the wireless charger, check the charger and the power adapter, and check the alignment between the wireless charger and the phone. Make sure your phone and wireless charger are compatible: Make sure your phone supports wireless charging and that the wireless charger is compatible with your handCompatible model number. Different phone models may have different charging standards, so you must use a wireless charger that supports your phone model.
First click the "Settings" option on the desktop of your phone. Then in the Settings page that opens, click on the "Battery" option. Finally, in the battery page, open the "wireless reverse charging switch".
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 Mate30 Pro is Huawei's smartThe mobile phone was unveiled in Munich, Germany, on September 19, 2019.
2, the first is actually electromagnetic induction, that is, the transmission of energy between two coils. You should have learned high school physics, and that's how transformers work, but transformersThe coil has an iron core. Tesla coil can achieve ultra-high pressure, because the coil is relatively loose, so that the magnetic field generated by the coil can escape the coil and directly act, without worrying about high pressure damage to the core. Tesla coils were therefore used to transmit commercial radio waves, but were later abandoned.
3, through the "Tesla coil" to obtain millions of volts of high-frequency voltage, the use of "amplification transmitter" (now known as high-power high-frequency transmission line resonance transformer) for wireless transmission. The principle is simple: the earth as the inner conductor, the Earth's ionosphere as the outer conductor, by amplifying the transmitter, using a unique radial electricityThe magnetic wave oscillation pattern establishes a low-frequency resonance of about 8 Hertz between the Earth and the ionosphere, using electromagnetic waves around the Earth's surface to transmit energy.
Principle of mobile phone charging booster circuit The mobile phone charging booster circuit is a circuit that can convert low voltage into high voltage to meet the needs of mobile phone charging. Its principle is: the low voltage is input into a transformer, the transformer converts the low voltage into a high voltage, and then the high voltage is output to the phone charger, and finally the high voltage is converted into the voltage required by the phone.
No circuit, it is estimated that you installed a simple charger for transformer rectification. 12V battery full voltage approxAbout 14V, the peak voltage of the 12V transformer through half-wave rectification is about 12*414-0.7=127V, and the bridge rectifier minus 0.7V is about 15V, which can be filled in theory.
Principle of boost circuit A boost circuit, also known as a boost circuit, is a circuit in power electronics. Its main function is to convert low voltage to high voltage. This is done by passing an inductor (usually an inductor) and a thyristor (usually a MOSFET or BJT). Inductors convert low frequency current into high frequency voltage through the principle of magnetic inductionThe thyristor controls the output voltage.
FP6291 is a CC (constant current) mode PWM boost IC, suitable for lithium battery (3 ~ 2V) output 5V, 1A mobile power applications. The FP6291 is packaged as SOT23-6 and operates at 1MHZ, which can be paired with 3uh small chip inductors to reduce the finished product size.
1, the first wired charging, this charging method with the development of science and technology to extend the flash charge, fast charge, the result is to help users quickly full mobile phone battery.
2, wireless charging than wired charging more damage to the battery. As long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more damage to the battery. Whether the line charge charges the battery is controlled by the internal circuit of the phone, and the internal control circuit of the phone works normallyThe initial voltage is provided by the battery.
3, in fact, we all know that as long as it is charging will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, the heat generated is relatively large damage to the battery. Whether the line charge charges the battery is controlled by the internal circuit of the mobile phone, and the initial voltage for the normal operation of the internal control circuit of the mobile phone is provided by the battery.
4, beautiful appearance: the design of this charging treasure is very fashionable, beautiful appearance, no messThe charging cable improves the beauty of the product and looks very tall. Protect device interfaces: Wireless charging avoids frequent insertion and removal of charging cables, reduces the risk of device interface wear, and is conducive to extending device life. Do not underestimate the wear and tear of this data interface, which will really affect the use of mobile phones.
5, wireless charging damage battery: wireless charging in addition to the charge can not be directly supplied to the hardware, other aspects have no impact. You said that the injured battery is wireless charging while playing will be far more than the wired battery, because the wired power supply does not use the battery, and the wireless is charging while discharging. longThe use of radio charging will not affect the phone battery.
