Temperature control circuit. The general wireless charging scheme will have a temperature control circuit and NTC thermistor, this function is mainly to prevent the circuit in the process of working to generate too much heat, burn components, etc., can also control the power components after generating too much heat, reduce the power, thereby reducing the temperature. Selection of heating componentsChoice. qi standard wireless charging is originally the use of electromagnetic induction, generate current, promote the circuit work.
Hot wireless charging mobile phone 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.
Wireless charger It is normal for mobile phones to get hot when charging, but if chargedFrequency phone fever serious shutdown normal?
1, using the correct charging posture to charge, you can obviously feel the heat is not so serious, only a little warm, is acceptable. Therefore, if you encounter serious fever when using wireless charging, you can adjust the position of charging the phone. For example, this wireless charger for personal use, point the top of the phone at the power cord of the charger.
2, long time call or voice problem: the use of call, voice, or video energy consumption is very large, the battery internal resistance increases, the current needs to be constant, part of it is consumed on the internal resistanceIt's causing the battery to heat up. While charging while playing mobile phone problem: Mobile phone charging will bring heat to the mobile phone, plus mobile phone programs, such as games, calls and other energy-consuming programs, the heat problem is "worse".
3, the iPhoneX heating up the reasons are as follows: the phone opened a lot of background applications, running high energy apps. Playing with your phone while charging will increase the temperature of your phone's battery. The mobile phone protective shell is too thick, blocking the normal heat dissipation of the mobile phone. The iPhoneX was released by Apple in the United States at 1:00 am Beijing time on September 13, 2017The new models were announced at the Steve Jobs Theater event at the new ApplePark headquarters.
2, wireless charger mobile phone charging heat is a normal phenomenon, but if charged to hot, we should pay attention to whether there is a problem with product quality. The original wireless charger does not rule out possible faults. In addition, when charging, pay attention to whether the power of the wireless charger matches the phone. For mobile phones that support wireless charging, just place the phone in the middle of the wireless charger to charge the operation, which is relatively convenient.
3, it is recommended that you use the standard charger to charge the use of other third-party chargers although you can also charge the phone, but because of the charging specifications or charging protocol differences, you canIt can cause problems such as heating the phone.
4, wireless charging, mobile phone fever is a normal phenomenon, but overheating may be dangerous. Wireless charging technology uses the principle of magnetic coupling to transfer power between the transmitter and the receiver. In this process, part of the electrical energy will be converted into heat, causing the phone and charger to heat up. This is a common phenomenon of wireless charging and does not mean there is a danger.
5, the root causes of mobile phone wireless charging fever are: the choice of program. This is the most fundamental reason, different solutions have their own characteristics, such as NXP, IDT, easy charging, XuWireless charging solutions, such as Xinsheng, are different in charging efficiency, mobile phone compatibility, or in disconnected charge, temperature control and so on.
1, wireless charger mobile phone charging heat is a normal phenomenon, but if charged to hot, we should pay attention to whether there is a problem with product quality. The original wireless charger does not rule out possible faults. In addition, when charging, pay attention to whether the power of the wireless charger matches the phone. For phones that support wireless charging, simply place the phone in a wireless chargerIn the middle of the charging operation can be carried out, which is relatively convenient. 2, in summary, wireless charging mobile phone hot is a normal phenomenon, mainly caused by the working principle of wireless charging, energy conversion efficiency, mobile phone heat dissipation design and use of the environment and other factors. When using wireless charging, it is recommended to pay attention to the heat dissipation of the phone and avoid charging in a high temperature or an airtight environment to ensure the safety and performance of the phone. 3. In general, although it is normal for mobile phones to heat up while wireless charging, continued overheating may pose a potential danger. So keep it appropriateThe charging conditions and observing the temperature changes of the phone are crucial.
4, wireless charging heating is a normal phenomenon, but there is a certain temperature range, generally marked in the manual, it is recommended to read the manual carefully before use. There are a variety of standards for wireless charging, and you need to check which charging standard your phone supports before buying.
5, the mobile phone will be hot when charging, the use of the same heat, if charging while using, will aggravate the fever phenomenon. You are advised to clear unnecessary applications in the background. If many applications are started in the background, you are advised to clear unnecessary applications in time.
1, wireless charging heating is a normal phenomenon, but there is a certain temperature range, generally marked in the manual, useIt is recommended to read the instructions carefully before proceeding. There are a variety of standards for wireless charging, and you need to check which charging standard your phone supports before buying. 2, in summary, wireless charging mobile phone hot is a normal phenomenon, mainly caused by the working principle of wireless charging, energy conversion efficiency, mobile phone heat dissipation design and use of the environment and other factors. When using wireless charging, it is recommended to pay attention to the heat dissipation of the phone and avoid charging in a high temperature or an airtight environment to ensure the safety and performance of the phone.
3, the phone will have some heat when charging, which is normal, because there will be a certain amount in the charging processThe loss of electrical energy, which is converted into heat, will keep the phone and charger warm, and the temperature will be higher if the phone is used when charging.
2, the battery caused by too much current is hot, if the battery is very hot that is suspendedUse, otherwise there will be a risk of explosion, the high current is strictly affecting the battery, but not too high temperature, the life of the battery has little impact. Wireless charging will not damage the mobile phone hardware, unless the power is too high, wireless charging will not affect the life, the heat is normal when the direct charge will also heat, but overheating is not good heat dissipation or wireless charging equipment has a problem.
3, you can search the relevant evaluation on the network, wireless charging technology really has been relatively mature, so the heat generated when wireless charging is really no harm to the mobile phone.
4, heating is a common phenomenon when the mobile phone is chargingIn particular, it supports fast charging and super fast charging mobile phones, and when charging, the current and voltage are larger, so the temperature will be higher than that of ordinary charging. If you are conducting wireless charging, because there will be energy loss in the wireless transmission process, and then generate a certain amount of heat, there will be a phenomenon of heat when wireless charging, this is normal.
