1, the loss of battery is the same. First of all, wireless charging and wired charging have the same loss of battery. 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 can not putThe charged electricity is directly supplied to the hardware, and there is no other impact. (2) Although wireless charging generates more heat, if appropriate heat dissipation measures are taken, the damage to the battery from wireless charging 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. 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.
3, wireless charging than wired charging more damage to the battery. In factWe 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 battery.
Apple wireless charging doesn't hurt cell phone batteries expand knowledge: The iPhone is an iOS operating system launched by Apple Inc. on January 9, 2007System series of mobile phone products.
While there are some less obvious benefits to wireless charging on the iPhone, there is also a big downside - one that could cause major damage to the planet's ecology. Wireless charging causes environmental harm We first discuss the harm of wireless charging function, because it is very important.
No harm. 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 transmitted only between coils resonating at the same frequency, and other devices cannotIn addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
iphone wireless charging does not hurt the battery. The principle of wireless charging is the built-in wireless charging function in the mobile phone, only need to put the mobile phone on the wireless charger, and wireless charging technology has been very mature, no damage to the battery behavior; Avoid playing with your phone while charging and charging your phone for too long to extend battery life. Because wireless charging uses the magnetic induction principle to charge the iPhone.
No. The wireless charger uses the latest wireless charging technology,By using alternating magnetic fields generated between coils to transmit electrical energy, inductive coupling technology will act as a bridge between charging base stations and devices. Wireless charging technology uses magnetic resonance to transmit electrical energy in the electric and magnetic fields between the charger and the device, and the coil and capacitor form a resonance between the charger and the device.
This has a little high-frequency radiation, but the impact on the human body is relatively small, but the wireless charging, itself is not efficient, the mobile phone is easy to heat, in cold areas, may have no impact, but for the hot summer, it will lead to overheating of the mobile phone, so that the battery itself will cause badInfluence, shorten its service life.
1, 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 speed: Since the Samsung Note 7 explosion, mobile phone wireless charging power has been castrated by manufacturers.
It is a charging treasure that supports wireless charging, so for the high price of 749 yuan, many netizens have mocked it, saying that it is useless accessories and IQ tax products. The reason why netizens do not look good and joke is mainly because the MagSafe external battery is not qualified as a charging bank, because its battery capacity is very small, and considering the problem of charging loss, it is not much help to improve the battery life of the iPhone.2, look at the individual, if you really do not like this function, there is no requirement for a full charge of time, it is indeed an IQ tax; But for those who rely heavily on this function, hotheadsFor example, this feature is very good.
3, and in China, there are not many companies studying this technology direction, so you can see that domestic products are QI standard chips, which is undoubtedly the cost and design.
1, low efficiency: energy storage and delivery efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. High cost: The charger needs to have the electronic circuit that pushes the wireless coil, while the electrical equipment is usedFor electronic devices that need to have power changes, both also need to have wireless coils, so the cost is higher than direct contact.
2, mobile phone wireless charging has the advantages of convenience, flexibility, protection interface, the harm is low charging efficiency, slow charging speed, high cost. Benefits Convenience: Wireless charging of mobile phones eliminates the hassle of using a charging cable. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable.
3, the benefits of wireless charging are: reduce lossHigh adaptation rate, the disadvantages are: the distance is too small, only 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.
4, the harm is relatively small can be ignored, although wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses the principle of "magnetic resonance" to allow the wireless charger to transmit an electric charge through the air to the phone's battery. Many wireless chargers on the market don'tRadiation values are indicated, and electromagnetic radiation standards for wireless chargers have not yet been introduced.
5, 3, better interface durability 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. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed, which is easy to oxidation corrosion.
6. Cult of Mac says another big downside of wireless charging is that it makes it much harder to use your phone while charging. With wired charging, users can move their phone while charging - although limited by the length of the cable. When using wireless charging technology, the phone must be placed on the charging pad, which is fine if the user just plays music while the phone is charging, but it is a pain to let the phone complete other functions.
