The reason why the wireless charger responds but does not charge: whether the phone model supports wireless charging or whether the wireless charger matches. Whether the wireless charger indicator is displayed normally. Mobile phone case and other wireless chargersExternal influencing factors. The transmitter power of the wireless charger may also lead to the reason why wireless charging can not be used.
Wireless charger usage is very simple, but some friends in the process of using wireless charger may encounter the situation of not charging into the electricity, the reason may be that the mobile phone does not support wireless charging, wireless charger does not match, mobile phone protective cover and other external factors, wireless charger indicator light display is not normal, etc. Let's take a look at how the wireless charger can't be charged.
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 charger. If you use a non-original charger, you may not be able to charge normally.
The wireless charger has a reaction but does not charge, which may stem from the following reasons: First, whether the mobile phone model supports wireless charging, or whether the wireless charger used matches the mobile phone model. Incompatible device combinations may result in an inability to charge. Second, check whether the wireless charger indicator light isThe display is normal. If the indicator light is not on or abnormal, you may need to replace the wireless charger.
Please check that the back of the phone is centered in the center of the wireless charging board. When there are inclusions between the mobile phone and the wireless charging pad, it may not be able to charge normally. 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.
Second, when using wireless chargers, if the device is not properly aligned with the charging pad or the charging distance is too far, the charging efficiency may be reduced, and frequent interruptions during the charging process will also cause additional burdens on the battery. Frequent charging interruptions may cause the battery to constantly re-enter the charging state, which will accelerate battery depletion in the long run. In addition, the quality of wireless chargers on the market varies.
Bad two: battery loss. Relative to wired charging, because the heat generated during wireless charging will be relatively high, wireless charging will actually have a slightly larger loss to the battery.
Bound: Wireless charging needs to be adsorbed on the charging base, and can not be moved at will, which is more restrictive to the user than the wired charge. High price: The principle of wireless charging is different, resulting in the cost of wireless chargers is usually higher than that of wired chargers. Low efficiency: Due to the low efficiency of wireless charging, under the same input power, the charging speed is slower than the line charging, especially the fast charging function of some brands.
Analysis reasons Most models do not support wireless charging because of the technology and cost of wireless charging, generally low-end models do not support wireless charging, only those high-end flagship has wireless chargingElectrical function. This means that only users who can afford high-end flagship have the opportunity to use wireless charging, the target group is limited, and it is still a relatively small part of the market, which cannot be popularized.
Wireless charging does not affect battery life. The following is a detailed explanation from the working principle of wireless charging, the factors affecting battery life, and how to use wireless charging safely. Wireless charging technology mainly transmits electrical energy through the principle of electromagnetic induction. In the process of wireless charging, there is no need for direct contact between the charger and the receiving device, but for energy transmission through the magnetic field.
2, Connect the power: Connect the wireless charger to the AC power supply, ensure that the charger is in working condition. Place the device: Place the device that needs to be charged (such as a mobile phone) on the charging area of the wireless charger. Make sure the device is between the chargerThere are no obstructions such as metal objects or other electronic devices. Start charging: When the device is correctly placed in the charging area, the wireless charger automatically senses and starts charging.
3, the use of wireless charger is very simple. First, make sure your device supports wireless charging. Second, connect the wireless charger to a power source, align it with your device and place it on it to start charging. Device compatibility: Before using a wireless charger, make sure your phone or other device supports wireless charging. Most modern smartphones have this feature.
4Put the mobile phone with wireless charging function on the wireless charging board, the position should be placed, you can charge, note that some wireless charging panel supports different mobile phone models, to choose wireless charging panel according to your mobile phone model.
5, the use of McDonald's wireless charger: find the port suitable for the mobile phone model, plug into the mobile phone charging port; Each table has a circular area with lots of "vinyl" records. Place the mobile phone with the round plastic sheet in the "black film" area of the table. Wireless charging technology (Wireless charging technology; Wireless charge technology, derived from wireless power transmission technology.
6. First, plug the USB cable of the wireless charger into the power socket to complete the power connection. When your phone is low or about to run out of battery, simply place the phone on the board of the charger, without the need for precise alignment. Once the phone and the charger come into contact, they immediately establish an inductive connection and start charging. During the charging process, the battery icon at the top of the phone screen will show the charging status, so that you can keep track of the charging progress.
1, the charge efficiency is not high. Once the distance is a little far away, the efficiency of charging will be dramatically reduced, and a lot of time and resources need to be wasted to complete the charging, so the use is not meaningful. Safety issues in the charging process. High-power wireless charging equipment will produce a large amount of electromagnetic radiation, which will cause certain adverse effects on health, but also have interference effects on aircraft and communications. The first practical aspect.
2, it is not convenient to carry, and it cannot be played while charging. Moreover, most of the wireless charging bases are designed to be more thanThe wired charging head is larger, and it is not very convenient to carry out. And when using wireless charging, the phone can not pick up and play while charging, can only say simple phone calls and listen to music. Encounter game play half of the phone power shortage, can only be wired charging faster and more convenient.
3, another major drawback of wireless charging is that it often limits us to a relatively close distance, and sometimes wireless chargers must put the phone in that position, if you move, this time the phone can not be charged at all. If some friends like to sit and play mobile phones, then wireless charging at this time limits the posture of playing mobile phones, veryIt's not convenient.
4, insufficient place is low efficiency, after all, there are transformers in the charger, because the wireless charger is composed of the transmitter coil and the acceptance coil transformer, so in the transmission of electricity, the efficiency is still lower than the general charger.
5, at present, the wireless charger technology is not mature, it is precisely because of such low charging power, compared with wired fast charging, there are still big shortcomings.
6, durable: the power transmission element is not exposed, so it will not be eroded by moisture and oxygen in the air; No contact exists, and therefore there will be no connection withLoss caused by mechanical wear and flameout during separation. Convenient: there is no need to connect with wires when charging, as long as it is placed near the charger, there is no need to occupy multiple power sockets, and there is no trouble of multiple wires winding each other.
