If you do not consider the heat, take Huawei P40 Pro Plus as an example, it supports 40W wireless charging and wired charging powerThere is no difference, but in the case of actual heat, wired charging is faster.
Different configurations, different charging methods, different colors. Now the wireless charging is basically the use of electromagnetic induction technology, electromagnetic induction wireless charging is the essence of magnetic generation, and the principle of the transformer, the sending end and the receiving end have a built-in coil, when the two ends are close, the sending end coil into the high-frequency alternating current, will be induced in the receiving end of the same frequency of electromotive force, and then through the rectifier filter to charge the end.
So wireless charging and wired charging are the same for mobile phones,The two harm to the mobile phone, the real impact of the mobile phone is the charging itself, but have to admit that wireless charging is continuing to develop.
Generally speaking, at least 20% to 15% of the richness should be left. So use 40 watts. At least you need a charger of about 50 watts. Otherwise, it is easy to burn out because the charger is too small. This brings security risks. If the traffic is too large. Easy to waste energy.
Wired charging is in the process of charging, the mobile phone can also be used, this is its advantage, wireless charging is to look better, but there is a drawbackPut there, when charging wirelessly, the phone is not used normally.
Each has advantages Wireless charging than wired charging : wireless charging is convenient, do not need to connect the mobile phone to the charger, put on the charging board can wireless charging than wired charging ; Wired charging Wireless charging is hotter than wired charging is more stable, and the charging speed is faster than wireless charging.
Wireless charging good. In wireless charging, the charger and the charged device do not need direct contact, easy to use, strong environmental adaptability, avoid wireless charging than wired charging 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 needs a wired charger, but also more wireless charging than wired charging hot wireless charging board.
Advantages and disadvantages of wired charging although there are small problems, but high efficiency and mature; Wireless charging is primarily convenient, but testing challenges need to be solved to ensure safety and efficiency. In the future trend, wireless charging is expected to develop, but technical problems still need to be solved. Wireless charging testing challenges Power transmission testing for wireless charging is particularly complex, requiring high accuracy and phase calibration.
1, the loss of battery is the same. Let's start with wireless charging and wired chargingElectricity drains the battery in the same way. Because whether it is wired charging or wireless charging, it is necessary to regulate the voltage of the electricity sent through the last step, but the path of the two is different. Wireless charging damage battery: Wireless charging in addition to the charge can not be directly supplied to the hardware, other aspects have no impact.
2, wireless charging than wired charging more damage to the battery. In fact, we all know that as long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more damage to the batteryBattery damage is relatively large.
3, wireless charging than wired charging more damage to the battery. As long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more 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.
4, although wireless charging generates more heat, but if the appropriate heat dissipation measures are taken,Wireless charging is not necessarily more damaging to the battery. While wired charging generates less heat, it may also cause damage to the battery if the charging current is unstable or if a non-original charger is used. The initial voltage for the normal operation of the phone's internal control circuit is provided by the battery, but if the battery is completely exhausted, even if the charger is inserted, the phone can not be turned on.
5, the bad will not be bad, that is, the two together have a little impact on the battery life, if you can try to use the line charge, wireless is just more convenient, on maintenance, the phone prefers the line charge. But the line will wear the interface, there are wear marks later sold second-handIt might drop a little bit. While there doesn't seem to be any evidence that wireless charging degrades smartphone battery performance any faster than wired charging, there are some tangible benefits.
6, cable charging. 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, and there is still room for further improvement in technology. The main culprit of charging damage to the battery is the battery heat resulting in internal damage to the battery.
Heating is a common phenomenon when the mobile phone is charging, the current and voltage are large, so the temperature will be higher than the ordinary charging. If you are conducting wireless charging, because there will be energy loss in the wireless transmission process, and then generate a certain amount of heat, there will be a phenomenon of heat when wireless charging, this is normal.
The mobile phone will have some heat when charging, which is normal, because there will be a certain loss of electrical energy during the charging process, this part of the electrical energyConverting to heat will keep the phone and charger warm, and even hotter if you use the phone while charging.
The reason for the heat is that the rapid movement of the electronic device current is the overall molecular movement speed, so that the sign of the intensity of molecular movement - temperature rise. The transformer in the charger needs to convert the household voltage, which is generally 22V, to a smaller mobile phone charging voltage such as 7V, 5V, and so on.
In fact, wireless charging is hotter than wired charging We all know that as long as it is charged, it will cause damage to the battery, but wireless chargingThe damage of the pool is greater, because more heat is generated when wireless charging, and the heat generated is more damaging to the battery.
Wireless charging hurts the battery more than wired charging. As long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more 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.
Whether it is wireless charging or wired charging charging time is long wireless charging than wired charging will hurt the battery, but compared with wireless charging and wired charging, because wireless charging will generate more heat in the process of charging, high temperature is not good for the battery, so wireless charging more damage to the battery. However, when using wireless charging, pay attention to ventilation. Huawei Technologies Co., Ltd. is headquartered in Bantian, Longgang District, Shenzhen, Guangdong Province, China.
Whether it is wireless charging wireless charging than wired charging , or wired charging wireless charging than wired charging , as long as there is charge and discharge behavior of the battery, there will be a certain loss. Wireless charging does not reduce battery life too quickly compared to wired charging. Of course, this premise is that wireless charging is hotter than wired charging You need to use a wireless charger that is suitable for the device. All in all, wireless charging is the same as wired charging, everyone can rest assured to use. The loss speed of the battery is mainly related to the number of charges and discharges.
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.
Whether it is wireless charging or wired charging, as long as there is a charge and discharge behavior of the battery, there will be a certain loss. Wireless charging does not reduce battery life too quickly compared to wired chargingLife. Of course, this premise is to use a wireless charger that is compatible with the device. Battery refers to the part of a cup, tank, or other container or composite container containing an electrolyte solution and a metal electrode to generate an electric current, and a device that converts chemical energy into electrical energy.
Wireless charging does not necessarily use more power than wired charging. Wireless charging technology uses magnetic field induction to transfer power without the need for a physical connection (such as a cable), so it is considered a more convenient way to charge. However, this technology doesn't actually use any more power than wired charging.
Wireless chargingThe device has an impact on battery life. The use of wireless chargers has an impact on battery life mainly reflected in the following aspects: First, the wireless charger generates current through the electromagnetic field to charge the device, and its charging method may be slightly less efficient than wired charging. This means that some heat may be generated during the charging process.
Some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
