Qi2: Next revolution in charging technology, check details

Delhi : While wired charging may quickly charge your phone at speeds of over 100W, it is rather inconvenient. It's not exactly a joyride to plug and unplug your phone. Not to mention ports that can develop dust blockages and cause your phone to charge slowly. Alternately, they may become wet, rendering your phone incapable of charging. These issues are quickly resolved by wireless charging. Placing your phone on a charging surface and letting it handle the rest of the work makes charging quite simple. However, even while it solves these issues, it still manages to introduce new ones.

Imagine placing your phone on the charger and going to sleep with the expectation that you will wake up to a completely charged battery. Instead, you discover that the phone was a few millimeters off-center and did not charge at all. Yes, magnetic wireless charging also exists, but due to the lack of a global standard, it's a bit of a mess. However, Qi2 might alter that and encourage the widespread usage of wireless charging. But what is Qi2, how does it operate, and what are the prerequisites? These queries are addressed below.

How does Qi2 function and what is it?

Let's first examine the operation of wireless charging. A transmitter coil in the charger transmits energy to a receiver coil in the device using electromagnetic induction. Because the coils are tuned to the same frequency, a magnetic field is produced that enables the energy to flow.

The latest wireless charging standard, Qi2, advances this innovation. For compatible phones, Qi2 achieves 15W rapid charging using magnetic alignment and a separate frequency. The charger and the device are perfectly aligned thanks to the magnets, which improve charging efficiency and speed. Additionally, Qi2 allows for simultaneous charging of multiple devices and charging through thicker casings and metal surfaces.

The Wireless Power Consortium (WPC), a collection of businesses that support wireless charging standards, created Qi2. During CES 2023, the WPC presented Qi2, calling it "the latest advancement in charging technology."

You might be shocked to find that Apple, using its MagSafe technology, contributed the most to Qi2. Apple launched the MagSafe magnetic charging method with the iPhone 12 series. The Magnetic Power Profile (MPP), which outlines how Qi2 operates, was created by the WPC using MagSafe as its foundation.

Due to its faster, safer, and more practical wireless charging for smartphones, mobile gadgets, and even wearables, Qi2 is predicted to overtake Qi as the industry standard. Despite the fact that Qi2 is compatible with existing Qi chargers and devices, you must use a Qi2-certified charger and device to fully benefit from Qi2.

What distinguishes Qi2 from Qi?

The original Qi standard mandates tight proximity and alignment between your phone and charger in order to maximize charging performance. Therefore, you cannot simply place your phone on the pad and anticipate that it will charge rapidly. In order to enjoy faster and more dependable wireless charging, Qi2 is a new standard that uses magnets to keep your phone and charger in the ideal position.

What advantages come with Qi2 magnetic charging?

In comparison to existing wireless charging standards, Qi2 is said to be faster, safer, more compatible, more progressive, and more environmentally friendly. This is why:

• Speed: Qi2 can charge at a maximum of 15 watts, whereas Qi can charge anywhere between 5 and 15 watts. This implies that you can charge completely in less than half the time. Additionally, Qi2 consumes less energy and produces less heat because it uses magnets to precisely align the charging coils.
  
• Qi2 is compatible with several iPhone 15 models and other MagSafe-enabled devices. Manufacturers of Android smartphones can also incorporate it into next models. This implies that you can share your charger with your friends and family or use it to power many devices simultaneously.
  
• Safety: Qi2 safeguards both your environment and your phone. Because it has improved foreign object identification, it only charges compatible devices and prevents damage or mishaps.
  
• Sustainability: Qi2 conserves resources and cuts down on waste. Fast-wearing charging wires wind up in landfills. Wireless chargers are not affected by this issue. They require less replacement and last longer.
  

What do I need in order to Qi2 charge my gadgets?

Unfortunately, there aren't many phones available with support for Qi2 because the standard was only recently released. In actuality, the only Qi2-compatible phone line available right now is the iPhone 15 series.

However, it is anticipated that Android phones would soon adopt the standard. Perhaps one of the Chinese companies, like Xiaomi or OnePlus with their future flagships, will outperform the competition. Or perhaps Samsung will astonish everyone next year with the Galaxy S24. You'll have to use bulky cords or the traditional Qi chargers until that time.
