Today to share with you the knowledge of the wireless fast charge of the mobile phone, which will also use the wireless fast charge of the mobile phone is safe to explain, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Although a few recently launched smart phones have sinceWith wireless charging function, but most of the current mobile phones still do not support wireless charging, or need to increase wireless charging receiver to experience the fun of wireless charging. This situation can not be changed in a short time, and the popularization of wireless charging still needs some time to transition. For users, the mobile phone wireless charging function is slightly chicken ribs, wireless charging is more like a icing on the cake function.
Support wireless charging mobile phones are very many, in addition to the traditional Samsung, Apple, Huawei's three flagship, Xiaomi is the most active in wireless charging, wireless charging technology is also ahead of others a big cut.Mobile phone wireless charging byThere is no need to plug and unplug the charging cable frequently, so the data interface wear of the mobile phone will be reduced a lot. At the same time, the coil of wireless charging of the mobile phone is not exposed to the air, which can also reduce the oxidative corrosion of the charging unit. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed, which is easy to oxidation corrosion. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process.
Charging curve: As can be seen from the curve: After placing the phone on the charger, the power meter soared to 18W, reaching full blood 15W operation. It only lasted about five minutesThe power drops to about 11W. At 10 minutes, with the sharp fluctuation of the moment, the output power of the power supply is reduced to between 5 and 5W, taking into account the efficiency of wireless charging, the actual charging speed is basically close to 5V1A. Initial charge 20%.
Versatility: a charger can charge multiple loads, and a family can buy a charger to meet the needs of the whole family. Versatility: Wide range of applications As long as the same wireless charging standard is used, such as the Qi standard, no matter which manufacturer's device can be wireless charging. Novelty, good user experience.
2, convenience: non-contact, one-to-many charging compared with the general charger, reduce the trouble of plugging, but also avoid the interface is not applicable, poor contact and other phenomenon, the elderly can also be very convenient to use. (2) Versatility: a charger can charge multiple loads, and a family can buy a charger to meet the needs of the whole family.
3, convenient: wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the phone interface, which can better protect the phone interface. Safety: With a variety of protection functions, such as: overcharge and overdischarge, metal foreign body detection and other functions, always protect the safety of users.
1, Apple mobile phone general we are better with direct charging, its charging effect is also a direct point, wireless charging is now a relatively newThe way, but I still accept the wired charge is better. I always feel that the money will charge the efficiency of the battery will be higher. The iPhone12 can be charged wirelessly or via wired.
2, apple straight. Direct charge can be charged fast, but also can play at the same time, wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. However, the conversion efficiency is best at about 80%, and the remaining electrical energy can only be converted into heat, so the heat of wireless charging has been a big problem. High-power wireless chargers also need to be paired with active cooling fans.
3Apple 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 magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.
4, apple straight. Direct charge can be charged fast, but also can play at the same time, wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. IPhone useLithium-ion batteries have the advantages of fast charging, long-lasting use, and higher power density and the ability to provide longer battery life in a lighter volume.
5, I think Apple mobile phone or wired charge is better, or more convenient, if you use wireless charging, in fact, in the wireless charging device to the back but also plug a wired charge power line, it can be energized, so I think wireless charging is still a chicken fin a product, It's just that you don't have to plug your phone into a charging port every time.
6, straight charge. Instant fastCharge and play at the same time. Wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. Wireless charging to take off the phone cover; Heat from the base will be transmitted to the phone; Low efficiency of wireless charging; Position deviation and leave the base can not charge; Charging time more than double; Wireless charging power 5W, playing the phone will not charge into, and will not hold the base to play.
1. Factors affecting battery life althoughSome people worry that wireless fast charging will harm battery life, but 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 effect, and appropriate "use with charge" is beneficial to battery health.
2, 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, OPPO Ace2 adopts 40W wireless flash charging technology, which takes into account charging efficiency and safety through series dual cell and air-cooled heat dissipation technology.
3. Of course the answer is no. So why would anyone think that wireless fast charging would hurt phones? Mainly due to the concern of frequent charging, the biggest benefit of wireless charging is that it is free from the bondage of the cable, each charge is taken and put, which reduces the cumbersome plugging and unplugging of the data cable more than the damage to the charging interface, but there are many users who frequently charge and power off will reduce the service life of the mobile phone.
4, wireless charging bank has no damage to the mobile phone batteryUh-oh. 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.
2, advantages: non-contact, no wire, mobile. Disadvantages: short distance, small power, poor efficiency. Low efficiency: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power.
3, wireless chargingThe advantages are: reduce the loss, high adaptation rate, the disadvantages are: the distance is too small, just the transition technology; The benefits of wireless charging reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then place the device that supports wireless charging on the wireless charging board.
2, 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 batteryThe damage is considerable. 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.
3, in fact, we all know that as long as it is charging 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, the heat generated is relatively large 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 lifted by the batteryFor it.
4, 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. However, the line will wear the interface, there are wear marks after selling second-hand may drop a little price. 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.
5, the degree of damage to the battery by wireless charging and wired charging depends on the charging method and battery temperature. Although wireless charging generates more heat, if takenAppropriate heat dissipation measures, wireless charging on the battery damage is not necessarily greater. 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.
About the use of wireless fast charge mobile phone is good and wireless fast charge mobile phone is good and safe is the end of the introduction, do not know you find the information you need? If you want to know more about this, remember to follow this site. < / p >
