1, the central position on the back of the phone. According to the relevant public information, the position of the wireless charging coil of millet 11Ultra is under the Logo of millet, in the central position on the back of the phone, the specific position can see the Xiaomi Logo on the back of the phone, the wireless charging coil is in the position below it. When you use the wireless charging board to wirelessly charge the Mi 11Ultra, just wireless the back of the phoneAlign the charging coil with the charging pad to charge.
2, the wireless charging coil is in the back plane, the transparent back cover, you can see the coil position. Xiaomi has 19 built-in coils, each of which supports 20W wireless charging, and can choose the right coil according to the placement of the product. The Mi 11 wireless charging position is in the middle of the back cover of the phone. The device with wireless charging function conforming to the Qi standard is placed in the center of the wireless charger, and the charging will automatically start.
3, in the central position on the back of the phone, the specific position can see the Xiaomi Logo on the back of the phone, wireless charging cableThe circle is just below it. When you use a wireless charging board to wirelessly charge the Mi 11Ultra, simply align the wireless charging coil on the back of the phone with the charging board to charge it. Mi 11ultra Wireless Charging coil location Mi 11ultra Wireless Charging coil Location In the phone Settings page, we click on the battery and performance column.
4, the wireless charging coil is in the back plane, the transparent back cover, you can see the coil position. Xiaomi has 19 built-in coils, each of which supports 20W wireless charging and can be selected according to the placement of the productThe right coil. Therefore, whether it is placed vertically, horizontally or diagonally, the millet multi-coil wireless fast charging board can almost achieve pairing and charging.
2, electromagnetic induction: simple and efficient close contact electromagnetic induction, like a pair of tacit understanding of the dancer, the sending end and the receiving end through the induction of magnetic flux transfer power. It is known for its simple structure, high efficiency and low cost, and is especially suitable for close-range device charging. However, it also has limitations, limited transmission distance and strict location requirements, requiring accurate alignment to charge, as shown in Figure 4-1.
3, the principle of wireless charging The principle of wireless charging is through electromagnetic induction or electromagnetic radiation, the energy is transferred to the need to chargeElectrical equipment. Specifically, wireless charging is divided into two ways: electromagnetic induction and electromagnetic radiation. Electromagnetic induction: Through the principle of electromagnetic induction, the current at the transmitting end is converted into a magnetic field, and then the energy is transferred to the receiving end through the magnetic field, and then the energy is converted into current, so as to achieve wireless charging.
4, the core of wireless charging technology is the electromagnetic induction principle. When a coil is fed with alternating current, it creates an alternating magnetic field. If another coil is placed in this magnetic field, it will also induce an electric current. This is the basic principle of energy transmission through magnetic field coupling. Wireless charging devices are divided into two types: connectReceiving end and transmitting end. The receiving end is responsible for converting the received electromagnetic wave into electrical energy to charge the device.
