Press and hold the power button, then follow the on-screen instructions to shut down and againCalled inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized. 3, wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
4, it is understood that wireless charging technology is achieved by two new devices, the first is the charger, it should be withPower is connected, and then there will be a "tray" and the charger for transfer, as long as the distance between the phone and the "tray" is within the specified range, then the phone will automatically wireless charging.
Apple flashlight can not open the reasons are: the phone temperature is too high, the phone battery is too low and so on. If you shoot video with the flash on for a long time, or use the device in a very warm environment, you may see a message indicating that the flash has been deactivated at this timeThe flashlight function will also be disabled, and the flashlight switch button will turn gray. This information will continue to be displayed until the device temperature drops.
The iPhone flashlight does not turn on the gray icon may be the following reasons: The flashlight is disabled: The shortcut key of the flashlight may be disabled in the control center. You can find the flashlight in Control Center in Settings and then enable it. Software problem: There may be a problem with the software on the device.

1, First answer no: Yes. The working power of the wireless charger is larger than that of the mobile phone, and the electromagnetic field energy radiated by the wireless charger is larger than that of the mobile phone. 2, conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life,Such as mobile phones, computers, WiFi, etc., long-term accumulation may have an impact on health. Wireless Charging Technology and controversy With the development of mobile Internet, the rise of wireless charging function has led to a discussion on electromagnetic radiation.
3, there is radiation is certain, otherwise the energy can not be transmitted across the space. The radio waves used for charging must be larger than the radiation power of the phone itself, otherwise the charging efficiency is too low. Calculated with a 1000mAh capacity lithium battery, 50% of the charging capacity is about 7~8Wh.
4, conclusion: Wireless chargers do produce electromagnetic radiation, although the value is relatively small, butThe cumulative effect cannot be ignored, and users need to be vigilant. With the popularity of wireless charging, the problem of radiation gradually surfaced. Wireless chargers transfer electrical charges through the air, and their working principle involves electromagnetic radiation. Experts say any wirelessly connected device generates electromagnetic waves, and the effects on the human body are complex and require long-term research.
