2. In order to simulate the real use environment, we use Apple iPhone 13 Pro and Huawei P50 Pro two phones as a fixed test machine. 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.
3, therefore, in the test must consider the charger, interface line and battery three aspects of matching, 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 meeting>
1, protection interface: wired charging requires frequent insertion and removal of the charging cable, long-term use may lead to interface damage or wear. Wireless charging eliminates this problem, and the phone interface can remain in good condition for a longer time, extending the service life of the phone. Low charging efficiency: Compared with wired charging, wireless charging is less efficient. That means it takes longer for users to fully charge.
2, wireless charger is good, convenient, safe, resistantUse; The disadvantages are bondage, high price and low efficiency. Advantages of wireless charger: Convenient: wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface.
3, the advantages of wireless charging are: reduce loss, high adaptation rate, the disadvantages are: the distance is too small, only the transition technology; The benefits of wireless charging reduce the loss. It is well known that when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then the device that supports wireless chargingPlace it on a wireless charging pad. 4, the benefits of wireless charger: from the theory, wireless charging technology is safe and harmless to the human body, the resonance principle of wireless charging is magnetic resonance, only in the same frequency resonance between the coil transmission, and other devices can not accept the band, in addition, the magnetic field used by wireless charging technology itself is harmless to the human body.
5, although the technical content of the equipment is high, the economic cost of the equipment is higher, and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. With wireless charging device distance and powerThe greater the dissipation of useless work will be.
6, the advantages and disadvantages of mobile phone wireless charging Mobile phone wireless charging is a convenient technological innovation, it eliminates the trouble of traditional wired charging, and users can charge more conveniently. However, it also has some advantages and disadvantages. Advantages: Convenience: Wireless charging eliminates the use of charging cables, and users only need to put the phone on the charger to achieve charging, eliminating the trouble of plugging and unplugging the charging cable.
1, power 5W charging slowly wireless charging has more difficult to break through the power limit, most of the wireless chargers on the market are 5W versions. Xiaomi wireless charger adopts Qi specification, which is the current common wireless charging specification for mobile phones, and even the iPhone X can be charged. However, most wireless charging is now a 5W version, and the charging speed is certainly not as fast as wired charging, let alone fast charging such as QC.
2, millet wireless charger is a portable charging equipment,Wireless charging for a variety of mobile phone models. The use method is very simple, you only need to turn on the charger, place the phone that needs to be charged on the charger, and the phone can start wireless charging. It should be noted that the Xiaomi wireless charger supports the Qi wireless charging protocol, so only phones that support the Qi protocol can be wireless charging. 3, March 27 afternoon, millet's new product conference, released millet wireless charger. Xiaomi wireless charger is a wireless charging product released by Xiaomi. Adopt 5W general charge and 5W Qi wireless fast charge. Xiaomi wireless charger exceptIn addition to charging the Mi MIX 2S, it can also be compatible with mobile devices that meet the Qi wireless charging standard. iPhone built-in lithium-ion rechargeable battery, support wireless charging function, suitable for all kinds of Qi chargers.
4, Xiaomi's free charger can charge the iPhoneXSMax. On the afternoon of March 27, 2018, Xiaomi released the Xiaomi Wireless charger at the new product launch conference. Xiaomi Wireless charger is a wireless charging product released by Xiaomi. Adopt 5W universal charging, 5WQi wireless fast charging. In addition to charging for Mi Mix2S, Mi wireless chargingAppliances are also compatible with mobile devices that comply with the Qi wireless charging standard.
The X70 Pro model does not support wireless charging. vivo/iQOO currently supports wireless charging devices are: iQOO 11 Pro, X90 Pro, X90 Pro, X Fold, iQOO 10 Pro, X80 Pro Snapdragon, X80 Pro Guet, X Fold, X Note, iQOO 9 Pro, X70 Pro, iQOO 8 Pro.
X70 Pro model does not support wireless charging, vivo/iQOO currently supports wireless charging models are: X70 Pro, iQOO 8 Pro.
QC0:18W (9V2A) PD: does not support vivo wireless charging: the maximum output of the charger is 30W, the mobile phone does not support the standard data line: 4A; X70Pro mobile phone support charging protocol: vivo flash charge: up to 44W (11V 4A/3A), support vivo super fast flash charge protocol; Ordinary charging: 10W (5V2A) vivo wireless charging: does not support Qi wireless charging: does not support reverse charging: does not support wireless, wired support.
X70Pro does not support PD fast charge, QC fast charge, you can see the charging protocol supported by X70Pro mobile phone: vivo flash charge: up to 44W (11V 4A/3A) Ordinary charging: 10W (5V2A) vivo wireless charging: not supportedQi wireless charging: do not support reverse charging: do not support wireless, wired support.
vivo mobile phones have wireless charging function, but not all vivo support wireless charging. Currently, the models that support wireless charging are: X80Pro Snapdragon version, X80Pro Guet version, XFold, XNote, iQOO9Pro, X70Pro, iQOO8Pro. Take vivoX70Pro as an example, vivox70pro supports 50W wireless charging, vivoX70Pro uses vivo self-developed SuperFlashCharge Ultra-fast flash charge. The maximum power of wired flash charge is 55W.
Among the new vivox70 series, only the top version of the vivox70 pro supports 50W wireless charging. vivo X70 Pro also uses vivo self-developed Super FlashCharge, which supports up to 55W wired flash charge, 10W reverse charge, and a battery capacity of 4500mAh. The basic version of x70 and the high configuration version of x70 pro only support 44w flash charge, the former battery capacity of 4400mAh, the latter battery capacity of 4450mAh.
1, 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 with 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 connector connection, so try to wipe the magsaf with a toothpick against an alcohol-soaked cotton balle female head, the effect is remarkable.
2, there will certainly be a slight heat, 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 quickly and safely wirelessly charge all MagSafe-enabled iPhone models, extending the life of the device.
3, this case is sure, passWired charging is often slow enough for iphones, as is wireless. And high-power wireless charging is sure to heat up. So it's normal.
