1, the loss of components affects the internal resistance of wireless charging fast and slow componentsSmaller, the system conversion efficiency is high. The selection of components such as triode with small internal resistance can greatly improve the efficiency of wireless charging. However, with low internal resistance, the cost will be relatively high.
2, charging method: The wireless charger must first load the iPhone into the charging protective case, and then place the protective case on the induction base, and then the induction base is connected to the power plug, and the power plug is plugged in. Connect peripherals: The iPhone connects peripherals in wireless charging mode, one is to take out the iPhone loaded into the charging protection case, the second is to connect Mini USB, and finally Mini USB connectionConnect peripherals.
3, the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
4, improve the transmission efficiency and reduce the loss rate. In order to improve efficiency, scientists are researching new materials, new antenna designs, and so on. By improving transmission efficiency, wireless charging time can be greatly reduced. In addition, there are new charging technologies are gradually maturing, such as wireless electron beam charging and resonance charging.These new technologies, while reducing attrition rates, can also lead to faster charging speeds and longer transmission distances.
1, the disadvantage of wireless charging is that most of the efficiency of wireless charging is relatively low. Because relying on electromagnetic induction to charge, often the speed is relatively slow, and sometimes it is necessary to quickly fill the phone, then it is obvious that wireless charging is not as good as direct use of the phoneData line fast charge.
2, convenience: non-contact, one-to-many charging compared with the general charger, reduce the trouble of plugging, but also avoid the interface is not applicable, poor contact and other phenomenon, the elderly can also be very convenient to use. (2) Versatility: a charger can charge multiple loads, and a family can buy a charger to meet the needs of the whole family. 3, wireless charging price is too expensive, comparable to two mobile phone wireless charger is not cheap, take the iPhone, wired charging only spend 148 yuan to buy a charger head, and wireless charging is not cheap, MThe price of the agSafe charger is 329, and the price of the dual charger is 1049. That's about the same price as some second phones.
1, first replace the charger or test with other devices to ensure that the charger can be used normally, and be careful not to place any items between the iPhone and the charger. If the iPhone does not charge or charges slowly, and the iPhone is equipped with a thick protective case, a metal protective case, or a battery outsideShell, please remove the protective shell or battery shell first.
2, the iphone wireless charging is slow, the reasons are as follows: because to take care of the cost, but also pay attention to security. Therefore, after testing and evaluation, it was finally determined that 7:5W is a safe and cheap solution for the new iPhone to achieve wireless charging, which is certainly much slower than the 15W wireless charging that can be supported now.
3, after testing, the iphone8 plus finally took about 210 minutes to fill yo, the specific can see the charging curve, the overall does not appear to be too big fluctuationsBoth are very smooth, but the charging speed is slower. However, it is said that the iphone8plus supports the fast charge function, and users can use the fast charge function to charge faster, but the only point is that the fast charge device is more expensive.
4. Connect the wireless charger to the power supply. Place the iphone8 on the sensor area of the wireless charger. You can see the phone start charging and wait patiently for the charging to complete.
5, this situation is usually caused by the fault of the phone charger. If the actual output voltage of the phone charger is lower than the rated output voltage, then charge overDuring the process, when the battery voltage of the mobile phone rises to a certain value, but the battery is not fully charged, the current voltage of the mobile phone battery is consistent with the output voltage of the charger, so there is no voltage difference that will cause the charging to stop. It is recommended to replace the charger for testing.
BMW 5 series wireless charging too slow can be replaced with a car charging port to match, this is the weakness of BMW 5 series wireless charging shortcomings.
Use the original charger to shut down and charge, and check whether the phone is powered off and chargedThere is a slow situation. If the phone only charges slowly when the phone is turned on, please: (1) End the background running program (recent application key in the lower left corner - End) (2) Uninstall the third-party battery management software in the phone. If the above operations do not work, see more solutions: (1) Check whether the phone has a version update, upgrade to the latest version.
It is recommended to change a high-power wireless charging board, such as a certain meter, which has more than ten coils, although it is not opened at the same time, the effect will be good.
Please check that the back of the phone is centered in the center of the wireless charging board. Mobile phone with wireless chargingWhen there are inclusions between the plates, it may not be able to charge properly. Please check the back of the phone. If the protective phone cover used is too thick may hinder wireless charging, it is recommended to remove the phone cover and try to recharge. Please use the original Samsung charger. If you use a non-original charger, you may not be able to charge normally.
Power plug power, wireless charger power, mobile phone wireless charging receiving power power plug power/wireless charger power/mobile phone wireless charging receiving power, these three key points are mutually complementary and mutually restrictive relationship, the final actual power is the smallest of these three items
