Wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Benefits of Wireless charger: Convenience: Wireless charging belongs to a pairMulti-charging 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.
Difference 3, convenience: when the phone is charging, the phone comes in but it is not convenient to answer in some specific situations. At this time, the convenience of wireless chargers is reflected. Simply pick up the charging case and move it to any place where the user can easily answer the phone.
Advantages of wireless charger: In theory, wireless charging technology is safe and harmless to the human body, and the resonance principle used by wireless charging is magnetic field resonance, which is only used in the fieldThe same frequency resonance between the coil transmission, and other devices can not accept the band, in addition, wireless charging technology uses the magnetic field itself is harmless to the human body.
Low frequency electromagnetic field (that is, like you said wireless charger, hair dryer type) will not have the heating effect of radio frequency electromagnetic field, the possible threat to human health is mainly: low frequency electric field and low frequency magnetic field will produce or induce current in the human body, if the current is large enough, can stimulate nerves and muscles.
Wireless charging bank does not harm the mobile phone battery. Because wireless charging now works on frequencies all doThe standard of future mobile phones, the Millet 7 released next year has basically determined that it will carry the same wireless charging module as the iPhone X.
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.
Benefit 1 Wireless charger : Reduce 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 in the wireless chargingOn the electric 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.
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.The receiver is essentially a coil, as we know, electromagnetic related technology, the need for bidirectional coil, through the change of magnetic flux, generate electricity. Arise as a resultThe shooting end and the receiving plate have a copper coil in essence, and the embedded circuit chip is controlled to complete the mutual conversion of magnetic energy and electric energy.
In addition to the advantages of convenience, wireless charging has many disadvantages. For example, the charging time is too slow, Samsung Note 5 fully charged at least 6 hours or so; If you use a fast charge, it will be full in a little more than 2 hours. Although wireless charging also supports fast charging now, it is still not as fast as wired charging, after all, wired charging already supports 40W fast charging, and wireless fast charging is only 15W.
1, whether it is charging the iPhone13 with 15W full blood, or charging the iPhone13 with the actual speed of close to 5V1A, the machine is always in a warm state. The biggest killer of batteries is electricity, and this temperature is enough to cause damage to batteries.
2, according to user feedback, the Apple 13 series wireless charging function is still better to useMore convenient and reliable. Since the Apple 13 series supports the Qi wireless charging standard, it can be charged using a wireless charger that complies with the Qi standard. All you need to do is place the iPhone 13 on a wireless charger to start charging. Compared with the traditional wired charging method, wireless charging can be more convenient to use, without worrying about cable damage or power failure.
3, conclusion: long-term use of the iPhone's MagSafe wireless charging has little impact on battery life, but the heat dissipation problem and charger choice is crucial. Concerns about wireless charging, especially forThe potential damage to the iPhone battery is actually not as rumored. Apple's MagSafe technology is based on the Qi wireless charging standard, which itself has evolved to support 30W fast charges. Apple's improvement is to improve charging efficiency through magnet design, rather than changing battery technology.
4, the iPhone13 supports MagSafe wireless charging technology, if you want to use wireless charging to charge your iPhone13, you need to buy a MagSafe charger. Of course, if you don't want to use wireless charging, you can still use traditional wiredCharging method to charge your iPhone13.
As of December 12, 2019, HUAWEI has the following mobile phones supporting wireless charging: HUAWEI Mate 30 5G, HUAWEI P30 Pro, HUAWEI Mate 20 Pro (UD), Huawei Mate RS Porsche Design.
Apple Wireless fast charge needs to meet the following conditionsTo turn on: Use Apple devices that support wireless fast charge: Apple devices that currently support wireless fast charge include iPhone 8 and later models, AirPods Pro, and AirPods 2 (require a wireless charging case). Use a charger that supports wireless fast charge: Apple officially recommends using Qi standard chargers that support 5W or more power, such as wireless chargers from Mophie, Belkin and other brands.
Huawei P60 Wireless charging is a new charging method that allows you to charge your Huawei P60 mobile phone without plugging in a cable. thisThe charging method uses a technology called "electromagnetic induction". When you use Huawei P60 wireless charger, you only need to put the phone on the charger, and the electromagnetic induction technology will let the phone automatically start charging.
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 are bothNo conductive contact can be exposed.
The addition of wireless charging function makes the charging method of iPhone12 more flexible and convenient. Compared with traditional wired charging, wireless charging does not need to connect cables, reducing interface wear and cable management trouble. In addition, with the development of wireless charging technology, wireless chargers can now achieve faster charging speed, although there is still a certain gap compared with wired fast charging, but it can meet the needs of most users.
Apple straight. Direct charge can charge fast, but also can play at the same time, wireless charging time is long and slow, and you can wireless when you do not use your mobile phone at nightCharge up. 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.
The Apple 12 has wireless charging. The Apple 12 series phones are equipped with a larger capacity battery and support for faster wireless charging technology, which can be charged wirelessly through the Qi standard. Users can choose to purchase an official wireless charger or other brands of compatible products to ensure that the output power and compatibility match the phone.
The Apple 12 has wireless charging powerI can. The iPhone 12 series phones support wireless charging, a convenience feature that Apple introduced in the series. Wireless charging is a convenient technology that allows users to charge their phone by simply placing it on a compatible wireless charger without using a traditional wired charger.
