1, you want to ask is why Apple mobile phone wireless charger mobile phone back hot? It's a normal phenomenon. Apple mobile phone using wireless charger for charging Apple wireless charge will overcharge , the back of the phone will be hot is a normal phenomenon. This is because when wireless charging Apple will overcharge with wireless charging , the phone is built inThe battery takes the electricity from the charger and converts it into electrical energy for storage. In this process, part of the electrical energy will be converted into heat, causing the back of the phone to burn.
2, wireless charging mobile phone hot is a normal phenomenon. In the process of wireless charging, the hot mobile phone is the result of a variety of factors. The following will explain in detail why the mobile phone will be hot when wireless charging from the working principle, energy conversion efficiency, mobile phone heat dissipation design and use environment. First, the working principle of wireless charging involves electromagnetic induction or magnetic resonance, both of which generate heat.
3, if you are conducting wireless charging, because there will be energy loss in the wireless transmission process, and then produce a certain amount of heat, there will be a phenomenon of wireless charging heat, this is normal.
4, temperature control circuit. General wireless charging scheme will have a temperature control circuit and NTC thermistor, this function is mainly for Apple wireless charging will overcharge to prevent the circuit in the process of working heat is too high, burn components, etc. You can also control the power components in the generation of Apple with wireless charging will overcharge iPhone 12 Pro Max can use the previous charger, but the charging cable attached is the USB-C plug (the red arrow position in the figure below), so you must replace the old USB plug to connect to the old charger, but note that the charging speed will be slow. When charging an iPhone, a better option is to charge the device through an outlet, which is more efficient. If you charge for a long time with a charger that does not match the current, the battery life will decay, which will have a certain impact on the mobile phone. Don't play while charging, especiallyIt's a video game, and the battery is hot enough to tell you it's time for a break. Usually play while filling, this habit will not make mistakes every time, but the probability of making mistakes will increase. w! The charging interface of iPhone 12 is lightning, so iPhone 12 series products will be equipped with USB-C to lightning cable, and then charge through USB connection to a computer or power adapter. It supports 20W wired fast charging and can charge up to 50% in half an hour, but requires a separate charger purchase. But like Huawei mobile phone if the superIn power saving mode, reverse charging is disabled. But the iphone12Pro max also has the following features: Support MagSafe wireless charging (power up to 15 watts), support Qi wireless charging (power up to 5 watts), can be charged via USB connection to the computer or power adapter, fast charging, 30 minutes up to 50% charge, need to use 20 watts or more power adapter. 1, generally not. The principle of the wireless charger is electromagnetic induction, the charger generates a magnetic field through the current, and the mobile phone generates a current through the magnetic field induction, so as to charge the mobile phone, the international standard is Qi charging, Apple mobile phone also supports Apple's MagSafe wireless charging. The most important thing that affects the battery life is the charge and discharge cycle of the mobile phone battery, that is, the process of the mobile phone from no electricity to full, and then from no electricity to full. 2, Apple xr wireless charging hurt the phone, it is recommended to use wired charging, wireless charging will make the body heat larger, will affect the battery life. IPhone EXR is the Appl of the United Statese (Apple) of the smartphone device, the body equipped with 7nm process A12 bionic chip, using TrueDepth camera, support FaceID function. In the early morning of September 13, 2018, the iPhone ExR was officially released at the 2018 Apple Fall New Product conference, starting at $749. 3, taking iOS11 system as an example, because iphone11 supports wireless charging, as long as the wireless charging voltage and current control is used within the Apple standard, then Apple 11 will not hurt the phone when it uses a wireless charger. Phone11It is the iPhone released by Apple in the United States at 1:00 am Beijing time on September 11, 2019 at the Steve Jobs Theater. 4, if the phone supports it, there is no problem. If the phone does not support it, it will not be charged with a wireless charger and will not damage the phone. Apple straightened. 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. The iPhone uses lithium-ion batteries, which have the advantages of fast charging, long lasting use, higher power density and the ability to provide longer battery life in a lighter volume. Apple mobile phone general we are better with direct charging, its charging effect is also a direct point, wireless charging is now a relatively novel way, but I still accept wired charging 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. This wired chargeIt will be better, some, because if you have wired charging, it will charge more efficiently, and wireless charging, it will be slower. There is nothing good or bad. As long as the battery is used, the battery life will be lost, which is a common problem of every mobile phone, and it is inevitable. Can wireless chargers damage iphones?
Is it better to charge an iPhone wirelessly or directly?
Does iphone wireless charging damage the battery
1, wireless charging it is just a new way of charging, theoretically will not damage the battery. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wire, so chargingThe device and the electrical device can be made without exposing the conductive contact.
2, Apple mobile phone wireless charging has no damage to the battery. Wireless charging technology is already complete, and many electronic devices are in use. There's no damage. iPhone is a series of smart phones developed by Apple Inc. It is equipped with the iOS mobile operating system developed by Apple Inc. The first iPhone was announced by Apple CEO Steve Jobs on January 9, 2007, and went on sale on June 29, 2007.
3. Conclusion: Ma of using iPhone for a long timegSafe wireless charging has little impact on battery life, but heat dissipation issues and charger selection are critical. Concerns about wireless charging, especially the potential damage to the iPhone's battery, are 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, iphone wireless charger does not harm the battery, because wireless charging technology has been very mature, wireless charging principle is used in the mobile phone built-in noLine charging function, just need to put the phone on the wireless charger to charge. Wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways, low-power wireless charging often uses electromagnetic induction, high-power wireless charging often uses resonance type by the power supply equipment to transmit energy to the power device.
1. Using magsafe to charge your iPhone won't hurt the battery. Charging normally with magsafe does not affect the batteryCause direct damage, but in theory the battery in the charging and discharging and use of the process will occur loss, compared with wired charging, magsafe use of magnetic charging heat is higher than the wired, and the battery in the case of high temperature loss faster, so magsafe is more likely to cause increased battery loss.
2, long-term use of MagSafe wireless charging will accelerate the loss of iPhone battery, mainly because of heat. However, understanding battery performance and mastering the correct charging habits can completely avoid this situation. Inside MagSafe and iPhoneThe device is highly sensitive to heat, so the charging power can not reach 15W most of the time, and the actual measurement is only 10W. Does magsafe wireless charging damage the battery?
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 the potential damage to the iPhone's battery, are 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. AppleThe improvement is to improve the charging efficiency through the magnet design, rather than changing the battery technology.
4. Yes, due to the high thermal sensitivity of the built-in components of MagSafe, charging will cause the mobile phone battery to heat up, which will cause loss of battery capacity, and long-term use will accelerate battery loss.
