The methods that can be taken in this case are: make sure that the phone is compatible with the wireless charger, check the charger and the power adapter, and check the alignment between the wireless charger and the phone. Make sure your phone is compatible with your wireless charger: Make sure your phone supports wireless charging and that the wireless charger is compatible with your phone model. Different phone models may have different charging standards, so you must use a wireless charger that supports your phone model.
Try to replace other wireless charging base for charging, locate the fault is this mobile phone or wireless chargerThe rate is usually lower than that of wired charging, which means that more energy is lost in the form of heat during wireless charging. This lost energy can cause the temperature of the phone and charger to rise. In addition, the heat dissipation design of the phone will also affect its temperature during wireless charging.
2, mobile phone charging heat is a common phenomenon, is charging, the current and voltage is larger, so the temperature will be higher than 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.
3, the reason for the heat is that the rapid movement of the electronic device current is the overall molecular movement speed, so that the sign of the intensity of molecular movement - temperature rise. The transformer in the charger needs to convert the household voltage, which is generally 22V, to a smaller mobile phone charging voltage such as 7V, 5V, and so on.
4, but wireless is not without shortcomings, because the principle leads to its conversion efficiency is not necessarily as good as wired charging. This results in more heat for the same power, which is why wired charging is higher without the need for air cooling.
5, In fact, we all know,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. Whether the line charge charges the battery is controlled by the internal circuit of the mobile phone, and the initial voltage for the normal operation of the internal control circuit of the mobile phone is provided by the battery.
6, the mobile phone and the wireless charger are arranged at both ends of the receiving/transmitting coil, the wireless charger current through the transmitting coil to generate a magnetic field, the mobile phone receiving coil close to the magnetic field will generate electricityThe current is then converted into usable DC by the rectifier and voltage regulator filter circuit built into the mobile phone. Well, it's a bit of a headache to look at this principle.
This situation is normal, due to the charge management function of Apple's MagSafe external battery. Both the MagSafe battery case and the iPhone can heat up when charging because they're left plugged in for a long time. Therefore, in order to extend the life of the battery, the charging may be limited toMore than 80%, it may automatically power off when it is charged to 80%.
magsafe is a little hot when used. Choose a MagSafe magnetic charger at home and at work, and a magnetic power bank for your daily commute. After Apple released the MagSafe external battery, in the actual experience, the MagSafe external battery did not have the serious heat of a third-party magnetic charging bank, and no heat was felt in daily use.
Charging your iPhone with magsafe won't hurt the battery. Use magsafe charge normallyElectricity does not cause direct damage to the battery, but in theory, the battery will be lost during charging and discharging as well as during use. Compared with wired charging, the degree of heat generated by magnetic charging used by magsafe is higher than that of wired charging, and the battery is lost faster at high temperatures, so magsafe is easier to aggravate the loss of the battery.
This is certainly the case, generally speaking, the iPhone wired charging is slow enough, wireless is the same. And high-power wireless charging is sure to heat up. So it's normal.
2, first of all, the emergence of this situation with Apple MagSafe external battery charging managementFunction is closely related. When charging an iPhone with Magsafe, both the battery case and the iPhone itself can generate heat due to being connected to the power source for a long time. In order to extend battery life and protect battery safety, Apple has set charging limits. Therefore, when the power is charged to more than 80%, for the long-term health of the battery, it may automatically power off.
3, iphone12magsafe does not charge this problem many people are reflecting, in fact, because magsafe wireless charging is too slow, resulting in many people think that it can not be charged, if you play mobile phoneSide charging, that is basically the same as no charging, so the magsafe charger effect is not much, not worth buying.
4, there may be two reasons for not being able to charge when using the wallet: the MagSafe wallet is thicker, plus after placing the card, it may not be possible to make wireless charging perfectly. Perhaps Apple is worried about damaging the magnetic strip or chip of the card to avoid unnecessary confusion to users.
5, If MagSafe does not fully charge the iPhone, it may also happen that your iPhone is charging, but not 10It is 0%. This could include optimizing charging. This means charging the battery to 80% to prevent wear and tear. This is not a flaw in the charger or the iPhone, but a conscious choice by Apple. Just before you take your iPhone out of the charger, it will charge to 100%.
1, temperature control circuit. General wireless charging schemes will have a temperature control circuit and NTC thermistor, whichThe function is mainly to prevent the circuit from generating too much heat in the process of working, burning components, etc., and can also control the power components after generating too much heat, reduce the power, thereby reducing the temperature. Selection of heating components. qi standard wireless charging is originally the use of electromagnetic induction, generate current, promote the circuit work.
2, 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.
3, wireless charging mobile phone hot is a normal phenomenon. wirelessDuring the charging process, 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.
