Charging your phone while talking on it won't necessarily harm your body, but it's best to minimize phone usage during charging. As wireless chargers become increasingly common, does the same principle apply to them? Today, let's have Feiyong Electronics shed some light on this issue.
The structure of a wireless charger includes high-voltage components, a power transformer, wireless charging coils, and low-voltage components. The high-voltage supply part is isolated from the outside world, with only the low-voltage supply part connected to the phone. The 220-volt AC current needs to pass through the high-frequency transformer of the wireless charger, ultimately converting into low-voltage direct current usable for the phone's output. Generally, the safe voltage for the human body is around 36 volts, and the output voltage of wireless chargers won't pose harm to humans.
Even if a short circuit occurs in a wireless charger, connecting the 220-volt high voltage directly to the phone, the phone's circuit will be immediately damaged, rendering it unable to function properly. Therefore, as long as your wireless charger is produced by a reputable manufacturer, safety is essentially guaranteed. However, the market is currently flooded with counterfeit chargers. Instances of phones being overcharged or even exploding due to the use of inferior chargers are not uncommon.
Nevertheless, from the perspective of battery life, it's best not to operate the phone while wirelessly charging.
We know that the lifespan of a battery is related to the type and frequency of charging. Nickel-cadmium batteries can generally be charged and discharged 100 to 150 times, nickel-metal hydride batteries 200 to 300 times, and lithium batteries 350 to 700 times. The longer the interval between each charge and discharge cycle, the longer the battery life. During charging, it's advisable to opt for slow charging whenever possible.
Some users' poor habits can indirectly lead to battery aging. Some people like to make phone calls, play games, browse social media, or download music online while their phones are charging. Typically, the voltage during charging is higher than during standby. If multiple operations are performed simultaneously, the chemicals in the battery will both charge and discharge simultaneously, leading to accelerated battery aging.
It's evident that the phrase "Don't use your phone while charging" isn't without reason.
Wireless charging has become increasingly popular with the advancement of technology. However, many users wonder if using a phone while it's wirelessly charging poses any risks similar to using a wired charger.
To address this concern, it's essential to understand how wireless chargers work and their impact on device safety and battery life. Wireless chargers consist of several components, including high-voltage parts, a power transformer, wireless charging coils, and low-voltage components.
The high-voltage components are isolated from the user and are responsible for converting the input voltage into a usable form for charging. The wireless charging coils transmit power from the charger to the device, eliminating the need for physical cables. The low-voltage components regulate the power output to ensure compatibility with the device being charged.
One of the primary concerns regarding wireless charging is the potential for electromagnetic fields (EMFs) to affect human health. EMFs are a form of radiation that is produced by electronic devices, including wireless chargers. However, numerous studies have concluded that the EMFs emitted by wireless chargers are not harmful to human health, as they are well below the safety limits set by regulatory agencies.
Additionally, wireless chargers are equipped with safety features to prevent overcharging and short circuits, reducing the risk of damage to the device or injury to the user. For example, most wireless chargers include built-in temperature sensors to monitor the device's temperature and prevent overheating.
While using a phone while it's wirelessly charging is generally safe, it's essential to use caution and common sense. Avoid exposing the device to extreme temperatures or moisture, as this can damage the charger or the device itself. Additionally, using a reputable wireless charger from a trusted manufacturer can help minimize the risk of damage or malfunction.
In conclusion, wireless chargers are a safe and convenient way to charge your devices. While using a phone while it's wirelessly charging is generally safe, it's essential to use caution and common sense to avoid potential risks. By following these guidelines, you can enjoy the convenience of wireless charging without compromising your device's safety or performance.
