1, mobile phone wireless charging because there is no need to frequently plug and unplug the charging cable, 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. Wired charging is frequentInsertion and removal may cause wear, and the interface is exposed, which is easy to be oxidized and corroded. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process.
2, advantage one: reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Benefit 2: high adaptation rate.
3, the disadvantages of wireless charging: can not charge while playing: the current wireless charger is basically a wireless charger base, there is no fixed position design, the mobile phone is difficult to meet the needs of charging while playing. Although there are also vertical wireless chargers that can solve this problem, it will still affect normal use.
Second, when using wireless chargers, if the device is not properly aligned with the charging pad or the charging distance is too far, the charging efficiency may be reduced, and frequent interruptions during the charging process will also cause damage to the batteryOutside the burden. Frequent charging interruptions may cause the battery to constantly re-enter the charging state, which will accelerate battery depletion in the long run. In addition, the quality of wireless chargers on the market varies.
Bound: Wireless charging needs to be adsorbed on the charging base, and can not be moved at will, which is more restrictive to the user than the wired charge. High price: The principle of wireless charging is different, resulting in the cost of wireless chargers is usually higher than that of wired chargers. Low efficiency: Due to the low efficiency of wireless charging, under the same input power, the charging speed is slower than the line charging, especially the fast charging function of some brands.
The cost is too high to choose to buy a mobile phone, charging cable and charging head is the standard configuration, and wireless chargingIf the panel is good, it will cost up to $100, if it is cheap, it will cost hundreds of dollars. The high price makes people feel that the cost performance is not good. People are relatively unfamiliar with wireless charging, which inevitably leads to some offensive psychology.
Mobile phone wireless charging is not popular, mainly because the wireless charging experience is very rubbish. Of course, the high price is also a very important factor. In terms of experience, mobile phone wireless charging has shortcomings. Compared with wired charging, wireless charging of mobile phones is not only slow, but also very inconvenient to use wireless charging. Slow charging: Since the Samsung Note 7 explosion, the phone is wirelessStart charging. This is undoubtedly a huge convenience for people who travel a lot or work outside the home. Modern wireless chargers usually have a fast charging function, and their charging efficiency is not inferior to that of wired charging.
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 removing of the mobile phone interface, which can better protect the mobile 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.
Advantages: Wireless chargingThe advantage of the device is that it can allow us to charge the phone while using it, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable. Disadvantages: One disadvantage of wireless chargers is that the charging speed is relatively slow, and most wireless chargers only support 5W or 5W charging power.
Honor 9 Premium version: With mature dual photography, HiFi sound quality, high appearance levelHu Ge endorsement and other features have attracted attention, becoming a popular flagship new machine. In terms of appearance, the front ceramic fingerprint Home button design is added for the first time, and the back uses the Aurora 3D curved glass rear shell, which integrates 15 layers of craftsmanship to create a dazzling laser effect with light and shadow, and the appearance is prominent.
The price is 2499 yuan. Redmi K50: This phone is the new product of Redmi K series, equipped with Qualcomm Snapdragon 870 processor, support 5G network, strong performance. Equipped with 5500mAh large battery, support 67W fast charge and 30W wireless charging, strong endurance. Use 67 inchesLCD screen, 2K resolution, 144Hz refresh rate, screen effect is excellent.
Mobile phones that support wireless charging are: Huawei Mate 40E Pro, Huawei P50 Pro, Huawei Mate 40E, Huawei Mate 40 Pro, Huawei Mate 30 Pro, Huawei Mate 20 Pro, Huawei P40 Pro, etc.
