We open the phone, click open Settings, enter the phone Settings interface. In the phone setting interface, we click on the battery to enter the battery setting interface. In the battery Settings screen, we click on Battery Health. In the battery health interface, we directly open the switch of wireless charging Apple dual charge wireless to Apple dual charge wireless . Prepare a wireless charger to charge the phone.
Open the iPhone13's Control center can be accessed by swiping down the screen or tapping the battery icon in the status bar at the top right corner of the screen. Find the "MagSafe" option in the Control Center, if it is not displayed, click "More Controls" and add it to the Control Center. Click the "MagSafe" option to make sure it is turned on.
The Settings screen is displayed. On the battery Settings screen, tap Battery Health. On the Battery Health Settings screen, tap to enable wireless charging mode. Wireless charging technology introduces wireless charging technology, that is, through the wireless way to set upExplore the principle and application of Apple's two-way wireless charging technology '> Explore the principle and application of Apple's two-way wireless charging technology The principle of Apple's two-way wireless charging technology is to use magnetic resonance technology Apple dual charge wireless by transferring electrical energy between two devices in close proximity. Specifically, Apple Dual charge wireless , this technology is based on the Qi standard, using a frequency of 5W. Make both devices Wirelessly Charged devices at the same time, so that they are separateResonance is formed under fixed frequency electromagnetic radiation, thus realizing wireless charging between two devices.
Technical principle Apple two mobile phone back-to-back charging technical principle is the use of Apple dual charge wireless wireless charging technology. When two iphones are placed back to back together, a magnetic induction coupling is established between them, enabling wireless charging. The technology requires both iphones to support wireless charging and not be too far apart. The advantage of Apple's two mobile phones back-to-back charging is convenient and fast.
iPhoneWireless charging uses the principle of electromagnetic induction. What is the principle of wireless charging for Apple mobile phones? The principle of wireless charging technology is actually the principle of electromagnetic induction. Children who have learned high school physics, I believe that everyone is very clear that electromagnetic waves have energy, can be obtained through the electromagnetic coil, and then the coil will form a current, and finally through the integration of the circuit can be charged.
Wireless charging technology is a technology that can transmit energy to a device through electromagnetic radiation without physical contact. Common wireless charging technologies include electromagnetic induction charging, magnetic resonance charging, radio frequency charging and so on. Among them, the A of appleThe irPower wireless charger mainly uses electromagnetic induction charging technology.
Users do not need to carry a charger and charging cable, only need to put two iphones back-to-back together to achieve charging. This way can also avoid the winding and damage of the charging cable Apple dual charge wireless , improving the safety of charging. The disadvantage of Apple's two phones charging back to back is the slow charging speed. Because the efficiency of wireless charging is lower than that of wired charging, becauseThe two iphones may take longer to charge back to back than from a charger.
After the WWDC conference, Apple officially released two 35W power dual USB-C interface chargers, priced at 399 yuan, which are now available worldwide. This charger is small and portable, making it ideal for charging two devices simultaneously at home, at the office, or while traveling. Apple recommends using it with the MacBook Air, but it can also charge devices like iphones, ipads, Apple Watches, and AirPods.
iphones cannot be reverse-charged. Because Apple's phone has not implemented this feature since the beginning, and AppleThe practical significance of reverse charging is not large, because the battery itself is not very large, so it is not possible to achieve reverse charging.
The Apple x can accept a phone that supports reverse charging for charging, because the Apple x supports wireless charging, but it cannot reverse charge other phones. Mobile phones that support reverse charging include iPhone XS series, Huawei P30 Pro, Samsung S10 series and so on. How to turn on P30 reverse charging Apple Dual Charge Wireless : Find the Settings in your phone and tap to enter. Tap the battery to enterBattery Settings screen. Tap Wireless Reverse charging below to turn this feature on.
