Wireless Charging vs Wired Charging – Which is faster?

The world of technology keeps evolving, and charging our devices is no exception. Until recently, we had to plug our phones and gadgets to a charger for hours at a time, but wireless charging has changed that. With less time spent searching for a cable or finding a socket, wireless charging offers a more convenient and effortless charging experience. However, many people still argue about the performance of wireless charging compared to wired charging. In our comparison, we look at whether wirelessly charging or using a cable is faster.

Wired Charging

Wired charging has been the standard method of charging for a very long time. Almost all devices come with a charging cable, usually USB, and the appropriate plug adapter. When plugged in, the charger sends electrical power to the device, restoring the battery's energy. Wired charging is fast and efficient, allowing devices to charge uniformly and quickly, thanks to the high voltage and wattage input it offers.

For instance, an iPhone 12 can charge up to 50% in only 30 minutes, reaching 90% with a cable charger in just an hour. A Samsung Galaxy S21 can reach 50% charge in 30 minutes and a full charge in 90 minutes.

Wireless Charging

Wireless charging, on the other hand, uses a magnetic field to transfer energy between two objects: the charging pad and the device being charged. The device rests on the charging pad, which powers the battery through resonant inductive coupling. Wireless charging has come a long way, with faster charging speeds and better efficiency.

Although convenient for charging, wireless charging is no match for wired charging in terms of speed. Currently, wireless charging is slower and less efficient than wired charging. Depending on the charger's wattage, it can take up to 2-3 hours to charge a device fully.

For example, Samsung's wireless charger with a 7.5W output takes 160 minutes to fully charge the Galaxy S21 from zero. An iPhone 12 on a wireless charger with 15W output will charge in two hours, while a 20W charger will charge it in 90 minutes.

Wired vs Wireless Charging – Which is faster?

While wireless charging is becoming increasingly popular, wired charging still reigns supreme when it comes to charging speed. If you're constantly on the go and need the quickest charge possible, go for a cable charger. Wired charging is convenient if you want to multitask and use your phone while charging since it transfers energy faster than wireless charging.

However, if you're looking for a charging solution with no cables or plugs, then a wireless charger is the way to go. If you're getting ready for bed or desk work and don't need your device to charge immediately, a wireless charger is a practical option.

Conclusion

Wired charging is undoubtedly faster than wireless charging when it comes to charging time. Wireless charging, while not as speedy, has its conveniences, such as freeing up ports and reducing cable clutter. Ultimately, both options have their advantages and disadvantages, so choosing between wireless or wired charging depends on your needs.
