wireless charging vs.  wired charging: differences and which one is better
Learn the differences between wireless charging and wired charging.

Currently, we are forced to charge our mobiles over and over again. The two most common ways to do it are wireless charging and wired charging. The first uses a very specific technology that manages to transfer energy without the need for cables, while wired charging is done through physical connections.

Both methods have their advantages and disadvantages in terms of comfort, efficiency and charging speed. In this article, we will discuss the differences between both options and assess which is the best option based on individual user needs.

4 key differences between wireless charging and wired charging

Cable charging is the most common way to recover autonomy in the mobile, in addition to the one that achieves the highest speed

Next, we take a look at four fundamental differences between wireless and wired charging.

Technology used

The first thing that differs between both systems is the technology used. Wireless charging works thanks to the electromagnetic inductionwhere a wireless charger transfers power via magnetic fields to the compatible device.

On the other hand, cable charging uses physical connectionsgenerally through a USB cable, to send electricity between two points. This is the most common way to charge a mobile device, not only because of its greater efficiency, but also because of the greater compatibility it offers. In short, all mobiles can be charged with a cable, but not all support wireless charging.

temperature reached

Another point that we must review is that of the temperature reached during the battery recharging process. Wireless charging tends to generate more heat compared to wired charging. This is because wireless power transfer involves the conversion of electrical energy into electromagnetic energy, which can result in higher temperatures during the charging process.

On the other hand, wired charging has a lower tendency to generate heat, since power is transferred directly through physical wires. However, this does not mean that this method does not generate heat. In reality, any type of charging raises the temperature of the battery, but induction usually does so to a higher degree.

charging speed

The charging speed is another aspect that differs between wireless charging and wired charging. In general, wired charging tends to be faster than wireless charging.

Obviously, wired charging offers a direct connection and can provide higher currentso it’s faster and more efficient. If charging speed is a priority, wired charging is usually the best option, especially in situations where you need to recover device autonomy in a short time.

Energy consumption and efficiency

Wireless charging is not as fast or efficient as wired charging, but it is much more convenient

Finished talking about energy consumption. what happens in this case? Well, wireless charging tends to be less efficient than wired charging. This is because some of the energy is lost during the transfer, due to factors such as distance and electromagnetic interference.

By comparison, wired charging has higher efficiency, as power is transferred directly through the physical connection. However, it is important to note that the difference in power consumption between the two methods is small and can vary depending on the devices and chargers used.

Advantages and disadvantages of each charging method

We close the guide talking about the advantages and disadvantages that each load method has. So you can determine which is the most convenient for you and how to apply them in your day to day.

wired charging

Advantages of wired charging:

  • charging speed. Wired charging allows faster power transfer and features shorter charging times.
  • Energy efficiency. By having a direct physical connection, wired charging prevents power loss and is more efficient compared to wireless charging.
  • Compatibility. This system is by far the most widely used in electronic devices. All devices have a charging port for a specific type of cable.
  • Stability. By using a physical connection, wired charging is less susceptible to EMI or signal fluctuations, providing a more stable and reliable charge.

There are some interesting cable-free solutions, such as Apple’s MagSafe-compatible magnetic charging stations.

Disadvantages of wired charging:

  • need for wires. Wired charging requires the physical presence of a cable connected between the charger and the device. This damages the aesthetics of the room where the terminal is charged, causes tangles and other problems related to the cable.
  • cable wear. The constant use of the cable causes wear in the medium and long term. This is usually not serious and can be fixed by replacing the cable, although you may also experience shock if the cable has been cut open at some point.

wireless charging

Advantages of wireless charging:

  • Comfort. Wireless charging is very convenient. Just leave the phone on a surface. The charger is always connected and waiting to be used.
  • Connector durability. By not requiring constant physical connections, wireless charging reduces wear and tear on the device’s connector, which can extend the life of the charging port.
  • Easy to load dark areas. Wireless chargers come with lighting for nighttime charging, making it easy to locate and charge devices in the dark.

Reversible charging works with the same technology as wireless charging and is great for charging small devices or even other phones.

Disadvantages of wireless charging:

  • charging speed. Compared to wired charging, wireless charging is typically slower due to energy efficiency and power limitations.
  • Sensitivity to distance and position. Devices need to be placed correctly on the wireless charger and keep a close distance to ensure efficient and stable charging.
  • mobility limitation. Although the physical cable connection also limits mobility, it is easier to manipulate the phone when it is connected in this way to the mains. In the charging bases it is not possible to move the phone or lift it from the surface. There are some intermediate solutions, such as the one proposed by Apple with its system MagSafe.
  • Generates more heat. Wireless charging may generate more heat compared to wired charging, which may affect device performance during prolonged charging.
  • Compatibility. Not all devices are compatible with wireless charging, as they require a built-in receiver coil or a specific case. To work with a wireless charger, your phone must include support for the wireless charger. Qi standard.
