Hey iQOO Fam,

In this series, we'll be diving straight into the Tech topic, how it works,pros and cons, also discussing the latest advancements and what's coming next.

Wireless charging has transformed how we power up our smartphones and gadgets, offering a cable-free, clutter-free experience. But what's the magic behind this technology, and which devices can you use it with today? Let's break it down and help you pick the best wireless chargers and pads for your needs.

How Wireless Charging Works

At its core, wireless charging is powered by the science of electromagnetic induction. Here's how it happens:

• Two Main Components:

A charging pad (or stand) that plugs into the wall.

A compatible device (like your phone) with a built-in receiver coil.

Working Principle:

• When you place your device on the pad, an electric current flows through a coil in the charger, creating an oscillating electromagnetic field. This field induces a current in the receiver coil inside your device, which is then converted into direct current (DC) to charge the battery.

Alignment Matters:

• The coils in the pad and device need to be closely aligned for efficient power transfer. That's why you sometimes need to “find the sweet spot” on the pad for charging to start.

Efficiency:

• Wireless charging is generally less efficient than wired charging because some energy is lost as heat. However, technology is improving, with faster charging speeds and better energy transfer.

Types of Wireless Charging Technologies

Inductive Charging (Qi Standard):

• The most common method, used by almost all modern smartphones and accessories. It requires close contact (within a few centimeters) between the pad and device.

Resonant Charging:

• Allows for slightly greater distance and flexibility in device placement, but is less common in consumer products.

Radio Frequency (RF) Charging:

• Still emerging, this tech can trickle-charge devices at a distance, but it's not widely adopted for phones yet.
