4, of course, wired charging fast, the current iPhone wireless charging only supports 15w wireless charging, and wired charging can support a maximum of 22w wired charging.
2, the Mi 9's 20W wireless flash enhancement test results show that its charging speed exceeds the 18W wired fast charge, and even faster than the Mi 8 wired fast charge. Lei Jun shared a comparison video in Weibo, taking the Xiaomi 8 as the experimental object, the two began to charge at the same time after running out of power, official data show that the Xiaomi 9 was fully charged in 1 and a half hours, and the Xiaomi 8 has completed 100% charging in 4 minutes.
3, different, the wireless charger will have a loss when charging, the loss is between 30-40 percent. So the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charge Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is wireless charge is faster than wired charge My own actual test results.
4, Method/steps Charging method: The wireless charger must first load the iPhone into the charging protection case: Wireless charging is less efficient than wired charging. That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmit and receive, it may lead to reduced battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge.

is different. Moreover, according to different wireless charger manufacturers now, the current and frequency are not the same. (The students themselves bought one online, it is said that the speed is relatively fast. The way to make it is to connect the metal pole of the wireless charger receiving device to the metal sheet of the charging electrode of your own phone, and then drag the wire outside to receive from the outside.) The heat is caused by the large current in the charger, which leads to obvious hairIt's hot.
Wireless fast charge is neither fast nor slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
Although the efficiency of wireless charging is lower than that of wired charging at present, in the future, with the rapid progress of wireless charging technology, charging efficiency will be improvedProbably better than wired charging. A stone aroused thousands of waves the vast number of netizens launched a crazy competition for this product. In the comments section of the Internet, a heat wave of wireless car charging was suddenly set off.
1, Mi 9 20W wireless flash enriched test: faster than Mi 8 wired fast charge With the progress of wireless charging technology, Mi 9 equipped with 20W wireless flash charge has shown good strength. Lei Jun confirmed in Weibo that the wireless charging of the Mi 9The speed does exceed the ordinary 18W wired fast charge, and proves this view by comparing videos, taking the Mi 8 as the experimental object.

3, Mi 9 support wireless chargingElectricity, charging power up to 20W. The Mi 9 can be fully charged in one and a half hours after using 20W wireless charging, which is faster than the wired fast charge of the Mi 8. Therefore, Xiaomi calls 20W wireless charging "wireless flash charging". At the same time, the Mi 9 has passed the German Rheinland YUV safety fast charging system certification, which has greatly improved the charging safety.
4, Mi 9 supports the world's first 20W wireless charging (through the German Rheinland safety certification), can be fully filled in one and a half hours, faster than Mi 8 wired charging. The Mi 9 has a 3,300mah battery with 27W wired fast charge as standard, 6It can be filled in 0 minutes. In addition, Xiaomi also launched the 20W Xiaomi wireless charger, priced at 99 yuan, and supports charging for the iPhone.
5. Support. At present, mobile phones that support wireless charging are: Mi 10 Supreme Commemorative edition, Mi 10/ Mi 10Pro, Mi phone 9/ Transparent Premium edition /Pro, Mi Mix 3/2S, and the rest of the mobile phones on sale do not support it.
Wireless charging accelerates battery loss and premature aging. When wired charging, the phone is powered by the charger, and the battery can stop output and get a rest; When wireless charging, the battery will not stop working, and with the consumption of power of the mobile phone, the electricity charged is consumed by the mobile phone, the battery has been in the working state, accelerating the battery charging cycle and shortening the life.
Cable charging is good. In the case of the same charging time, the power of the commonly used wired battery charger is 93% after charging, and the power of the wireless charger is 88% after charging. Obviously, there is still a gap in the charging efficiency of wireless chargers in technologyThere is room for further improvement.
Wireless charging good. In wireless charging, the charger and the charged device do not need direct contact, easy to use, strong environmental adaptability, avoiding the physical interface, so there will be no interface wear, sparks, leakage and other problems, in addition, wireless charging can also achieve high voltage, high current, high power charging. The cable is charged. Wireless charging also requires a wired charger, but also more wireless charging board.
Wireless charging is better. The convenience of wireless charging Wireless charging provides users with great convenience. For example, some public places, such as cafes, restaurants and airports, are providedWith the wireless charging service, users simply place their phone on a charging mat without carrying an additional charging cable. In addition, wireless charging technology is also being applied to furniture and cars, allowing users to charge at any time at home and in the car.
Apple cable charge well. The advantage of the magnetic magnet is that it can be adsorbated near, and the adsorption can be charged. The charger is automatically aligned with the position of the charging coil, which solves the problem of manual alignment for traditional wireless charging. But it is still a wired form, and the power is not as good as wired charging, so the key moment or wired charging is more realistic. If the MagSafe magnet charger wants to go pro, it needs toLook when the charging port was removed from the iPhone.
For us, mobile phones are basically wired charging. Because, to buy a wireless charging device price is still relatively expensive. Advantages and disadvantages of Apple wireless charger Advantages and disadvantages of Apple wireless charger 2: low charging efficiency, slow speed due to wireless charging, although much slower than wired charging. Even Apple's own wireless chargers can't charge as fast as wired ones.
