What is wireless charging?
Wireless charging
Wireless charging (also known as induction charging) is a technology that enables charging the battery of Xiaomi, Oppo, Samsung, and other phones... in the traditional charging style through a power cord or charging dock. It's the kind of charging that can power up your device without the need to plug a cable into your smartphone. Just place it on a pad or a built-in power-integrated stand to kickstart the charging process.
The working principle of wireless charging
In theory, wireless charging utilizes two resonant coupling connection points to transmit low voltage signals between two devices. These connection points are designed to transmit electricity without the need for physical contact like conventional wired connections.
Moreover, the charging module consists of a spiral transmitter, and the mobile device must have a spiral receiver to receive signals from the transmitter and convert them into charging processes for wireless charging to occur.
Two electronic spirals are specially designed to generate a magnetic field between the transmitting and receiving devices. This magnetic field will generate electric current through voltage differences and frequency oscillations, and this energy flow will be transferred to your phone.
Currently, there are several standards for wireless charging, such as Qi on Xiaomi Mi 11 256GB green or Wipower, A4WP. In general, these standards only differ slightly in the form of generating magnetic fields. In essence, they operate similarly.
What do you need to do to wirelessly charge?
What do you need to do to wirelessly charge?
To use wireless charging, you need to meet two conditions: your phone must support wireless charging and you need a wireless charger. The wireless charger can be a charging pad or various small charging mats of different shapes and sizes. Nowadays, some cafes in Vietnam offer wireless charging support, such as StarBucks Coffee, The Coffee Beans. Or you can search for wireless charging pads priced at a few hundred thousand dong in the market.
Advantages and disadvantages of wireless charging
Advantages and disadvantages of wireless charging
Advantages:
- Reduces the risk of accidents from low-quality wired chargers causing fires or explosions.
- Compact and lightweight, eliminating the need for multiple tangled cables, cumbersome charging docks, or intricate power banks.
- Eliminating the need for tangled and complex wires, wireless charging technology makes charging your phone simpler and safer compared to conventional methods.
Disadvantages:
- The biggest drawback of wireless charging is that you can't charge through metal, meaning phones with metal casings like aluminum or steel can't be charged. This means that most smartphones that want to use wireless charging must have a back made of glass or plastic.
- Charging phones with wireless technology takes longer and also makes the phone hotter compared to wired charging methods.
- Keeping the device constantly in a charging state will decrease the battery's lifespan.
However, with the numerous benefits of this wireless charging method, phone manufacturers like Xiaomi, Samsung, Oppo, Vivo are focusing on developing and enhancing this technology to new heights.
