Normal, 4Two degrees is not too hot. No more than 45 degrees is fine. Wireless fast charging base input power is large, low efficiency, the base is also hot, the mobile phone is placed on the base, the mobile phone is hot when followed, and it is not good to heat. The base has a cooling port and the fan automatically dissipates heat, so it won't be hot.
The mobile phone will have some heat when charging, which is normal, because in the charging process there will be a certain loss of electrical energy, this part of the electrical energy into heat will make the mobile phone and the charger to keep warm, such as the use of mobile phone temperature will be higher when charging.
Mi 9 charger is USB-A port, support USB PD requires USB-C mouth; In addition, the built-in protocol chip of the Mi 9 charger does not support USB PD, in summary, the Mi 9 charger does not support the USB PD protocol.
The new generation of Mi 9 supports wireless charging, charging power up to 20W. Xiaomi wireless charger is a wireless charging product released by Xiaomi. Adopt 5W general charge and 5W Qi wireless fast charge. Support MIX2S and Apple iPhoneX, iPhone8, etc. On the afternoon of March 27, 2018, Xiaomi held a new product conference in Shanghai and released the Xiaomi wireless charger.
2, when the vehicle is in the holding accessory power mode, the wireless charging function may not correctly indicate the charging situation. The operating temperature of the charging system is -20°C to 60°C, and the operating temperature of the mobile phone is 0°C to 35°C. To charge your smartphone: Remove all items from the charging pad. If there are any items between the charging pad and the phone, the system may not be able to charge.Place the phone face up on the charging pad over the charging strip.
3, whether wired charging or wireless charging, the charger or mobile phone will normally charge heat, under normal circumstances, the mobile phone charging temperature below 40 degrees, charging head (or wireless charger) temperature below 60 degrees at noon, can be considered normal, the lower the temperature the better.
1, high power wireless charging heat dissipation problem wireless charging temperature range rootThe reason is that the high-power wireless charging on the market now relies on high current for charging, but this situation is tantamount to increasing the resistance, thereby increasing its temperature, so it is necessary to use high-heat absorption and high-heat dissipation materials as the outer packaging, in addition, it is necessary to reduce the resistance accordingly, so as to fundamentally reduce the heat.
2, it is recommended that you use the standard charger to charge using its wireless charging temperature range Although his third-party charger can also charge the mobile phone, but due to the differences in charging specifications or charging protocols, it may bring heat to the mobile phoneQuestion.
3, generally the use of metal heat dissipation can reduce the heat transfer to the mobile phone, thus affecting the mobile phone charging power, is bound to increase the metal block on the circuit board or coil, a bit similar to the notebook CPU plus copper tube heat dissipation. Or increase the active fan heat dissipation, and use the fan to cool the motherboard and coil, which can achieve the delay power reduction time.
4, temperature control circuit. General wireless charging scheme will have a temperature control circuit and NTC thermistor, this function is mainly for wireless charging temperature range 5, normal, 42 degrees temperature is not high. No more than 45 degrees is fine. Wireless fast charging base input power is large, low efficiency, the base is also hot, the mobile phone is placed on the base, the mobile phone is hot when followed, and it is not good to heat. The base has a cooling port and the fan automatically dissipates heat, so it won't be hot. 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. It is normal for mobile phones to heat up when charging, especially for mobile phones that support fast charging and super fast charging. When charging, the current and voltage are larger, so the temperature will be higher than ordinary charging. In order to avoid serious heating of the mobile phone, it is recommended that you: (1) useCharging comes standard with a charger. It is normal for the mobile phone to heat up while charging: It is recommended that you do not perform high-power operations such as surfing the Internet, playing games, watching videos, or making calls while charging. It is recommended not to open a large number of third-party applications at the same time, which will not only cause a sudden increase in traffic, but also increase the heat of the phone. It is recommended to avoid long-term use of the phone while charging. It is normal that the current is large at the beginning of charging and the charging head temperature is high, and the charging head temperature will gradually decrease with the gradual rise of the battery voltage. About the mobile phone charging heat problem: the mobile phone will have some heat when charging, which is normal because it is chargingThere will be a certain loss of electrical energy during the electricity process, and this part of the electrical energy will be converted into heat to keep the phone and charger warm, such as using the phone while charging the temperature will be higher. When the smart phone is running, the mobile phone processor memory is in an operational state, which will generate heat, in addition, the mobile phone screen will also generate a certain amount of heat when working for a long time, and the transformation of energy when charging the mobile phone is stored in the battery will also have a certain heat phenomenon. In short, when using a mobile phone, especially when using some high-power functions, there will be a certain temperature, which is a normal phenomenon. In the process of charging while using, the temperature of the phone will be higher than normal charging because of the APP running, the screen lighting and other reasons. The current fast charge and super fast charge functions can realize fast charging, it is recommended that you wait until the charging is complete before using the phone; You are advised to manually select a more balanced charging configuration. Is it normal for Huawei to charge at a temperature above 37℃ for the first time?
