Wireless fast charge will not be veryFast, not too 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.
Wireless charging has the requirement of the distance between the mobile phone and the wireless charging panel, so a very thick mobile phone protective case or back bracket will cause the distance to exceed the effective receiving range or "virtual charging" phenomenon.Appropriate charging mode, real-time monitoring of the charging state of the phone, in order to ensure the normal operation of the phone power supply.
For this situation, Apple has explained on the official website: when connected to the USB, the iPhone will not be charged wirelessly. If your iPhone is connected to your computer via USB, or connected to a USB power adapter, the iPhone will be charged via the USB connection.
Mobile phone charging, wired charging and wireless charging, will automatically choose wired charging, ignore wireless charging. Wired charging is efficient and fastCharging speed is fast. Plug in wireless charging and then plug in wired charging, wireless charging will automatically stop and switch to wired charging. Wireless charging in wired charging will ignore wireless charging and still continue wired charging.
Although at this stage, the efficiency of wireless charging is lower than that of wired charging, in the future, with the rapid progress of wireless charging technology, it is likely to be better than wired charging in charging efficiency.
Low charging efficiency: compared to wired charging,Wireless charging is less efficient. 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.
Different, the wireless charger will have a loss when charging, and 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 charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is the result of my own actual testing.
1, the loss of components affects the internal resistance of wireless charging fast and slow components, and the conversion efficiency of the system is high. The selection of components such as triode with small internal resistance can greatly improve the efficiency of wireless charging. However, with low internal resistance, the cost will be relatively high.
2, charging method: the wireless charger must first load the iPhone intoCharge the protective shell, and then place the protective cover on the induction base, and then the induction base is connected to the power plug, and the power plug is plugged in. Connect peripherals: The iPhone connects peripherals in wireless charging mode, one is to take out the iPhone loaded into the charging case, the second is to connect the Mini USB, and finally the Mini USB connects the peripherals.
3, the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the center of the wireless charger base, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguishment, that is, plugUse, easy and quick.
Xiaomi 40W wireless fast charge first test Wireless fast charge efficiency : An unimaginable efficient experience at two o 'clock in the afternoon, Xiaomi announced wireless fast charge efficiency the birth of its 40W wireless flash charge technology, for 4000mAh battery, the official claim only100% charge in 40 minutes. Sina mobile phone the first time to bring wireless fast charging efficiency detailed field tests, let us explore the performance of this new technology.
Xiaomi 40W wireless fast filling test: rapid charging to show strength Xiaomi today officially released wireless fast charging efficiency its latest 40W wireless fast charging technology, the highlight of this technology is to provide amazing charging speed for 4000mAh batteries. After a field test of Sina's mobile phone, we can find out. measuringThe trial was conducted in the Mi Home, and the Sina phone used a specially modified Mi 10 Pro and Xiaomi vertical wireless fast charging device.
Xiaomi Group vice President Chang Cheng announced that Xiaomi's first device equipped with 40W wireless flash charge has been officially exposed. The technology is the fastest in the industry, with a 100% charge in just 40 minutes for a device with a 4000mAh battery. Chang Cheng stressed that Xiaomi's new wireless flash charging technology continues its leading position in the field of fast charging, and even the battery of the Magic Mi 10 Pro can be filled in 40 minutes.
Vice President of Xiaomi GroupCut Changcheng announced at 2pm today that Xiaomi's first device equipped with 40W wireless flash charging technology was officially unveiled. The highlight of this technology is that for 4000mAh batteries, it takes only 40 minutes to achieve 100% charging. Xiaomi's wireless flash charge technology once again refreshed the speed record, 40W wireless flash charge to maintain the industry's fastest record, in the magic Mi 10 Pro battery to achieve efficient and low temperature charging experience, leading wireless charging into a new high-speed era.
At the recent 5G era charging technology communication meeting, Xiaomi took the lead in demonstrating its 30W wireless flash charging technology, this innovative technologyIt will be first applied to the Xiaomi 9 Pro 5G mobile phone and is expected to be released soon. Impressively, the 30W wireless flash charge is able to charge a 4000mAh battery to 50% in just 25 minutes, while a full charge takes only 69 minutes.
Samsung Galaxy Note 5 released Wireless fast charge efficiency A new wireless charging pad: Samsung Fast Charge Wireless Charging Pad< /strong> Wireless fast charge efficiency , support fast charging function, according to Samsung claims that this wireless charging pad, than the ordinary wireless charging pad is 4 times faster charging speed, It only takes 50 minutes to go from completely dead to fully charged. At present, this charging version can only achieve fast charging on the Galaxy Note5 and Galaxy S6 Edge.
With Samsung's fastCharging technology, only 120 minutes, Note5 can be fully charged, and wired charging takes only 90 minutes, greatly improving the charging efficiency. In terms of appearance design, this wireless charger uses a unique disc shape, resembling a flying saucer, which is full of science and technology.
Samsung is not satisfied with this, in its latest business flagship model Galaxy Note5 took the lead in supporting wireless fast charging, 120 minutes full charge, so that users can experience wireless charging convenient at the same time, but also get faster charging speed, improve the use of fragmented time charging experience and efficiency, to provide battery lifeMore reliable security.
