In general, car wireless chargingThe conversion efficiency of electrical appliances is limited, but by rationally choosing chargers, we can improve this situation. Although the speed of wireless fast charging is not fast, it is not too slow, and consumers should pay attention to the power and actual charging efficiency of the charger when purchasing.
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. unexpectedlyHowever, the input 18W also needs to charge for 2 and a half hours, and the wireless fast charging efficiency is 60%.
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. The thickness distance/charging Angle/metal barrier will have a great impact on the wireless charging experience.
Cable fast charge, half an hour to 61%. 0-100 takes only 63 minutes. Wireless flash charge to 55% in half an hour. 0-100 takes 74 minutes.
For the products currently on the market, IThe summary of the poor experience is as follows: 1 Low charging efficiency Since it is for mobile phone charging, the speed of charging is of course the first, even if you can do "wireless than wired" in the application, but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
In the charging speed, the wired fast charge is definitely more than the wireless fast charge. From the data point of view, the current wired charging has reached the highest 50W mass production charging, Huawei 40W fast charge compared to OPPO 50W fast charge, and the fast charge power of other mobile phone manufacturers is basically more than 18W. Even in smartphonesThe slowest charging Apple also supports PD fast charging. Recently, Xiaomi and vivo have more than 100W of super charging power (not yet mass-produced).
Wireless charging on mobile phone batteryOften no damage. Wireless charging converts electrical energy into special energy through electromagnetic induction and transfers it between magnetic fields to achieve charging of mobile phone batteries. This charging method does not require the use of data cables, making charging more convenient and safe. Under normal circumstances, wireless charging operates at a frequency below 1MHz and will not affect the phone's communication signal.
No, wireless charging does not degrade the battery's performance any faster. Battery manufacturers design the amount of energy stored in batteries to determine the amount of electricity we can use. The manufacturer sets a fixed upper cut-off voltage and a lower cut-off voltage, and in both voltagesElectrical cycling between ranges, as long as we choose the right voltage range, we can make the battery cycle thousands of times.
Wireless charging bank does not harm the mobile phone battery. Because the working frequency of wireless charging is now below 1M, it will not affect the signal of the mobile phone. On the contrary, wireless chargers not only reduce the use of data cables, but also make charging methods more free and safer. It is basically the same as wired charging, but the rate is lower, but the wireless charger still has a high energy conversion rate, which saves energy consumption more.
Wireless charger itself will not cause damage to the phone batteryUh-oh. The principle of the wireless charger is to use magnetic field induction technology to generate a magnetic field between the charger and the mobile phone, thereby transmitting electrical energy to the mobile phone battery. In this process, there is no physical contact or chemical reaction, so there is no harm to the battery. However, if used improperly or frequently, wireless charging may have a certain impact on battery life.
No harm in this case. Wireless charging technology transmits electricity through electromagnetic induction, and the transmission method is different from that of wired charging. Under normal conditions of use, the wireless charger can provide electricity stably without adverse effects on the battery. In order to ensure the health of the battery, it is necessary to pay attention to the quality of the charger and the use environment, avoid a long-term high temperature environment, and protect the mobile phone battery to the greatest extent.
1, in fact, wireless fast charging , when wired charging wireless charging at the same time wireless fast charging , the iPhone will refuse the input of wireless charging and continue to be wiredCharging mode charging. That will not explode the problem, of course, will not exist, because the iPhone's power management IC will intelligently select the current most suitable charging mode, real-time monitoring of the charging state of the phone, in order to ensure the normal operation of the phone's power supply.
2, for this situation, Apple has officially conducted a wireless fast charge meeting on the official website. Wireless fast charge meeting : When connected to USB, the iPhone will not wireless charge. If your iPhoneConnect to a computer via USB, or connect to a USB power adapter, and the iPhone will charge via USB connection.
3, mobile phone charging, wired charging and wireless charging, will automatically choose wired charging, ignore wireless charging. Wired charging efficiency is high, fast charging 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.
4, if you use two kinds of charging at the same time, such as using a wireless charger and LightnWith the ing charging cable, the iPhone 12 Pro Max will only select one charging method to charge and ignore the other charging method. This means that the phone will only draw power from one charger, and the other charger will not have any effect on the phone. Using two chargers at the same time does not have any negative effect on the phone, but it also does not increase the charging speed.
5, only one of the effective. The other one doesn't respond. Generally, the plug line is charged directly as a priority, ignoring the wireless charging base. Haven't tried. Not interested in wireless charging.
1, no, every mobile phone battery and motherboard has a charge management chip. It controls the voltage, protects the phone and the battery. Therefore, it will not affect the service life of the mobile phone battery.
2, factors affecting battery life Although some people worry that wireless fast charging will damage battery life, in fact, wireless fast charging itself will not. Battery life is affected by a variety of factors, such as faulty charging habits (excessive discharge and frequent charging), high temperatures, and non-compliant charging devices. Lithium batteries have no memory effectShould, the appropriate "use with charge" is beneficial to battery health.
3, electromagnetic induction, magnetic resonance, wireless fast charge will not affect the life of the battery.
4, however, wireless fast charging does not directly lead to reduced battery life. Battery life is affected by a variety of factors, lithium batteries have no memory effect, frequent charging, power off does not affect. What can really damage a battery are wrong charging habits, high temperatures, and substandard charging equipment. For example, the 40W wireless flash charging technology used by OPPO Ace2 takes into account the charging efficiency through series dual cell and air-cooled heat dissipation technology
