Gadgets and other devices have improved dramatically over the last couple of years. This isn’t just about what the gadgets can do or what it looks like, but also how it can receive power. For many years, gadgets have relied on wired charging devices. However, as time went on, people have developed much better wireless charging options.
Today, there are so many wireless charging technologies to choose from. These wireless charging tools are all aimed at cutting cables to everything starting from things like smartphones and laptops to kitchen appliances and even cars.
Wireless charging is worth all the hype as it promises increased mobility as well as advances that could allow devices to get power without being chained to a wired cable. Read on to learn the advantages and disadvantages of wireless charging on mobile phones.
What is Wireless Charging
Simply put, wireless charging is the way a device can gain power without being connected to a cable. The main purpose is to connect with the object to charge or recharge the battery of any devices such as smartphones.
Nowadays, the most popular wireless devices rely on an electromagnetic field between two copper coils. This greatly limits the distance between a gadget and the charging pad.
How a Wireless Charger for Smartphone Work?
Currently there are three types of wireless charging. The first one is charging pads that rely on tightly-coupled electromagnetic inductive or non-radiative charging. Second variety is closer to charging bowls or through-surface type chargers. Charging bowls rely on loosely-coupled or radiative electromagnetic resonant charging that is capable of transmitting a charge a few centimeters away. Last category is more like an uncoupled radio frequency (RF) wireless charging that allows trickle charging at a distance of many feet.
Coil size is one of few factors affecting the distance of power transfer. Smartphone wireless charging pads often use copper coils that are a few inches in diameter. This severely limits the distance over which power can travel efficiently. In other words, the more coils being used, the greater of distance a charge can travel.
Advantage of Wireless Charging
- The main benefits of wireless charging is no more dragging a long data cable to charge. All you need to do is lean the phone gently on the charger. Just by doing that the current will be continuously charged into the phone right away.
- Wireless chargers tend to be more convenient as they mainly use the principle of electromagnetic induction to charge the phone. That means there is no interface between the phone and the charger. It doesn’t really matter what the brand of the phone is, as long as it is compatible with the wireless charging standard of the charging head then the phone can be charged.
- This method of charging offers you better interface durability. Wireless charging doesn’t require frequent plugging and unplugging which overtime can wear and tear the data interface of the mobile phone. Keeping in mind that the coil for the wireless charging of mobile phones isn’t exposed to air, that means there is less risk of oxidation and corrosion.
Disadvantages of Wireless Charging
- One of the main disadvantages of wireless charging is the short distance. The effective charging distance is only 3-8 mm. Mobile phones need to be close to the charger in order to effectively carry out wireless charging.
- Another one is low charging efficiency. The wireless chargers on the market generally have only 15W power. This is rather small compared to the charging power of wired charging which is generally 40-50W.
- Playing with the phone while charging is out of the question. It’s basically impossible to play with a mobile phone while it has to lie flat to the charger. You can still perhaps use a headset to connect and to listen to the phone while charging. Lastly, wireless charging tends to be more expensive.
Mentioned above are the advantages and disadvantages of wireless charging on mobile phones. There is still a lot of room for development on both charging devices. So, in any case choose one that fits all your needs and budget.
