The expert spoke about the principles of wireless charging

Modern users have at their disposal a variety of gadgets that make life easier, but require attention due to the need to recharge them periodically. Ilya Kazakov, technical director of the MTS Yurent Paverbanks service, told Izvestia on December 28 about how wireless charging works and how to choose it.

"Wireless charging works on the principle of electromagnetic induction, that is, energy is transferred from one device to another without direct contact through cables," Kazakov explained.

According to him, two coils are involved in the process of wireless charging: one is in the charger and the other is in the smartphone. When the gadget is placed on the charger, a magnetic field is created that transfers energy from one coil to the other, charging the smartphone's battery. This process requires both coils to be close to each other, otherwise the efficiency of energy transfer is reduced.

According to an expert, an important factor for wireless charging is power. Standard wireless devices usually offer around 5 watts of power, and this is quite slow. Meanwhile, fast charging can reach 10 watts or more, which speeds up the process considerably.

In addition, there are many options for wireless chargers, among them pads, which are simple and practical, perfect for most situations. Charging stands allow you to conveniently use your phone in an upright position, which is especially convenient when watching videos, for example. Wallet-style chargers are great for use in the car or in the workplace.

"A factor to consider when choosing a wireless charger is its additional capabilities. For example, charging multiple devices at once is handy if you have a lot of gadgets. Still in the unit can be built in a fan to prevent overheating of the device, and light indicators to demonstrate the status of charging," - summarized Kazakov.

Earlier, on November 3, the technical director of the service "Paverbanks MTS Jurent" Ilya Kazakov told "Izvestia" about applications that quickly drain the battery of the phone. According to him, the battery is drained by GPS navigation applications, as well as those that are constantly running in the background, downloading new content and sending notifications.
