Middle of the back of the phone. According to check Zhongguancun online Wireless charging minimum coil , xiaomi12su wireless charging coil is located in the middle of the back of the mobile phone Wireless charging minimum coil , close to the back cover of the mobile phoneWhen using the wireless charging function, the phone needs to be placed on the wireless charger. Wireless charging refers to wireless charging technology, derived from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways.
The Mi 12 wireless charging coil is fixed between the main and secondary board covers. Millet 12 uses a small inductance coil to sense the sending end energy, millet small inductance charging scheme uses the wireless charging minimum coil receiving coil, the inductance value is only about 1/3 of the traditional scheme, under the same conditions, the loss can be reduced to more than half of the traditional coil. In handThe rear cover. The Mi 13 wireless charging is located on the back of the phone, the same as the wireless charging coil on most mobile phones.

The back cover of the phone. Wireless charging minimum coil He is in the back cover of the phone, the same as the wireless charging coil of most mobile phones, it can be said that most mobile phone wireless charging induction coil position is basically in
The distance of the wireless charger can only be effective within the coil range of the charger Wireless charging minimum coil , more than the distance can not receive charging, each manufacturer's product is different, can not be universal.
We often say that wireless charging actually has great limitations, the effective distance is generally only 8 mm -15 mm, in this range can be normal wireless charging, the so-called space is separated from the wireless charging minimum coil a mobile phone shell empty. If the space between metal and the like, it will affect the normal fillingElectricity.Technology In principle, Qi charger and receiving equipment built-in conductive coil, the base power generated after the electromagnetic field will promote the receiving equipment coil into electricity, to achieve efficient and convenient wireless power supply. Although the Qi 2 standard supports fast charging up to 15W, the limitation of charging distance (typically a few millimeters to a few centimeters) remains a technical challenge. The two main highlights of Qi wireless charging are its convenience and versatility.
Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. bigPower wireless charging is usually resonant (most electric vehicles are charged in this way) by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
Of course, the range of this non-radiating electromagnetic field is more limited, not suitable for long distances, requiring the transmitting end and the receiving end to be within 8 times the radius of the induction coil. We all know that electromagnetic waves can be used to transmit information, so in theory, as long as the frequency is high enough, it can also be usedTransmit energy.
However, the efficiency can not reach 100%, the transmission distance is not far, generally not more than 25 cm, the farther the efficiency is lower, at 5 cm away the distance efficiency may not exceed 50%.
The central location inside the phone. When charging, keep the center position of the phone aligned with the center position of the wireless charger to carry out wireless charging. Mi MIX4 is equipped with a 4500mAh large battery, supporting 120W wired fast charge, 15Minutes can be filled, and 50W wireless fast charge, with millet 100W wireless charging dock, 28 minutes full.
The back cover of the phone. He is on the back cover of the phone, the same as the wireless charging coil of most mobile phones. It can be said that the induction coil of most mobile phones for wireless charging is basically in the back cover, and will not be placed in other positions, because the top of the phone will also put nfc.

Enable the wireless charging function. The wireless charging coil is located in the backplane, and the transparent back cover allows you to see the position of the coil. Mi built-inThere are 19 coils, each of which supports 20W wireless charging, and the appropriate coil can be selected 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.
Mi Mix 3 wireless charging coil is located on the back cover. Mi MIX3 integrates the NFC coil and wireless charging coil on the back cover, and links with the motherboard in the way of contacts.
