Wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
In general, wireless fast charge is a wireless charging method based on magnetic resonance, electromagnetic induction and other technologies, which eliminates the tedious operation of wired chargingUsers bring more convenient and efficient charging experience. Its wide application and continuous technological development indicate that wireless fast charging will become the mainstream way of charging electronic devices in the future.
Wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending end coil is connected to the wired power supply to generate electromagnetic signal, the receiving end coil induction electromagnetic signal to generate current to charge the battery, can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and the charging heat is lower and betterDot.
w Wireless fast charge refers to the wireless fast charge technology power up to 50W. The 50W wireless charger can almost complete the entire charging process of the 4500mAh large-capacity battery in less than 50 minutes. That's about the same speed as most wired fast charges today.
wmax wireless fast charge is the abbreviation of wireless charging function, but also represents the wireless charger. This charger can not be connected to the socket, very convenient. It has the function of fast charging. With the function of fast charging, it does not need the data cable to charge the phone directly, and only requires the user to put the phone as noCharging can be done directly near the line charger. The following is a detailed example to introduce this wireless charging method.
And now the wireless fast charging technology is more and more developed, most of the mobile phones support the qi standard, that is, the manufacturers will support qi wireless fast charging in the introduction. You need a wireless charging chassis, plus an 18-watt or 30-watt fast charger. The second is that the phone needs to support the function in order to achieve the so-called wireless fast charge. Manufacturers are also moving faster and faster in the development of this technology.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.
Mobile phones that support the wireless fast charge protocol use the official original wireless chargerIt will not damage the phone battery when charging. Data development: How to deal with mobile phone fever when wireless charging: It may be because the mobile phone opens high-power applications when wireless charging, such as: King of Glory, Tencent video and so on. When the app is opened, the CPU efficiency of the phone increases, increasing the power consumption, which causes the phone to heat up.
2, the mobile phone that supports the wireless fast charge protocol will not damage the mobile phone battery when charging using the official original wireless charger. Data development: How to deal with mobile phone fever when wireless charging: It may be because the mobile phone opens high-power applications when wireless charging, such as: King of Glory, Tencent video and so on. The app opensAfter that, the CPU efficiency of the phone will increase, increasing the power consumption, which will cause the phone to heat up.
3, wireless charging in addition to the charge can not be directly supplied to the hardware, other aspects have no impact. You said that the injured battery is wireless charging while playing will be far more than the wired battery, because the wired power supply does not use the battery, and the wireless is charging while discharging. Long-term use of radio charging will not affect the phone battery.
4, as long as it is charged will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging is more damaging to the battery, because wireless chargingMore heat will be generated, and the heat generated will cause greater damage to the battery. Whether the line charge charges the battery is controlled by the internal circuit of the mobile phone, and the initial voltage for the normal operation of the internal control circuit of the mobile phone is provided by the battery.
5, no, wireless charging will not reduce the performance of the battery 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 electrical cycling is achieved between the two voltage ranges, as long as we choose the right voltage range, we can cycle the battery thousands of timesTime.
6, wireless charging will not affect battery life. The following is a detailed explanation from the working principle of wireless charging, the factors affecting battery life, and how to use wireless charging safely. Wireless charging technology mainly transmits electrical energy through the principle of electromagnetic induction. In the process of wireless charging, there is no need for direct contact between the charger and the receiving device, but for energy transmission through the magnetic field.
Wireless fast charge is neither fast nor slow. Wireless fast charge ratio noneFast line charging is much faster than fast line charging is slower. 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.
In general, the conversion efficiency of car wireless chargers is limited, but by choosing a reasonable charger, we can improve the situation. Although the speed of wireless fast charging is not fast, it is not too slow, and consumers should close it when buyingNote the power of the charger and the actual charging efficiency.
Many people worry about the harm of electronic devices to the human body, but in fact, this is not need to worry, the closed magnetic field is very safe, will not interfere with the mobile phone signal, and low temperature fast charge function, charging will not heat. Of course, the most important thing is the charging effect, wireless charging although relatively slow, but the effect is still very stable.
However, wireless fast charging does not directly lead to shorter 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, OPPO Ace2The 40W wireless flash charging technology is adopted, and the charging efficiency and safety are taken into account by series double cell and air cooling heat dissipation technology.
In theory, wireless fast charge and mobile phone fast charge, are specifically designed for mobile phones, there is no harm to the mobile phone battery, for this point still need to understand. However, when the user chooses a wireless charger, it is best to choose a charger that is compatible with the mobile phone, or choose a charger produced by a regular manufacturer.
Unqualified third-party power adapters and data connection cables do not have over-voltage and over-current protection, which is easy to cause unstable charging power and cause batteriesDamaged. The official recommendation is 0 ° C ~35 ° C is the ideal working environment for iPhone, too high or too low temperature will have a certain impact on the phone battery.
And under such a damage curve, within the basic life of the mobile phone, the use of fast charge will not cause much impact on the battery life of the mobile phone. So we can think that, in fact, the use of mobile phone fast charge will not cause too much loss to the mobile phone battery, at least within the national standard is enough for us to use. In terms of technological theory, every scientific and technological development today is backed by scientists.
In fact, when wired charging and wireless charging are carried out at the same time, the iPhone will refuse the input of wireless charging and continue to charge in wired charging mode. 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.
High charging efficiency, fast charging speed. Plug in wireless charging and then plug in wired charging, wireless charging will automatically stop and switch to wired charging. Cable charging medium plug noneWire charging, will ignore wireless charging, still continue to wire charging.
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.
Wireless and wired charging at the same time is not a bad problem, but it also does not have any benefits, and it also causes unnecessary (albeit small) power consumption. So I suggest not hereCharge your mobile phone.Cannot be charged at the same time. Only one charging method can be selected. For mobile phone charging safety, when connected to wired charging, the mobile phone will automatically switch to wired charging, wireless charging will be stopped. Wireless charging technology (English: Wirelesschargingtechnology; Wirelesschargetechnology is derived from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
