How Wireless Charging Works?
Wireless charging, also known as inductive charging, is a method of transferring electrical energy from a power source to a device without the need for physical connectors or cables. This technology utilises electromagnetic fields to transfer power, making it possible to charge devices by simply placing them on a charging pad or station.

The Role of Electromagnetic Fields
At the heart of wireless charging lies the concept of electromagnetic fields. These fields are created when an electric current flows through a coil, generating a magnetic field around it. When another coil is placed within the proximity of this magnetic field, it induces a current in the second coil, effectively transferring electrical energy from one coil to the other. This process is known as electromagnetic induction.
Components of a Wireless Charging System
A typical wireless charging system comprises two main components: a transmitting coil and a receiving coil. The transmitting coil, often embedded within a charging pad, is responsible for generating the electromagnetic field. On the other hand, the receiving coil is integrated into the device that needs to be charged.
How the Charging Process Unfolds
If you’re wondering how wireless charging works, here is the process. Basically, when a device with wireless charging capabilities is placed on the charging pad, the transmitting coil generates an alternating current (AC) through it. This AC current creates an oscillating magnetic field around the coil. The receiving coil within the device detects this magnetic field and converts it back into an electrical current, which is then used to charge the device’s battery.
Does Wireless Charging Work with a Case?
Yes, your case can work with wireless charging, but it comes with some limitations. As a general guideline, wireless charging does its thing to a certain extent, yet if your case is too thick, your phone might not get charged properly. Now, the big question is, what’s the thinnest your case should be to keep the charging flow going? While there are some super thick cases out there, crafted for an extra layer of shield, most cases won’t give you a hard time. However, select a phone case that is wireless charging friendly.
When it comes to wireless charging pads, they usually fit with cases that are up to three millimeters thick. Keep an eye out for aluminum cases, though – they can mess with wireless charging vibes. Interestingly, the move towards glass over aluminum in the latest iPhones is believed to be connected to wireless charging requirements. Also, don’t forget about the quality of your wireless charger. In general, the better the charger, the more likely it is to connect through thicker cases.
Always use a screen protector, regardless of whether you have a case on your device. The screen on your phone is, after all, both its most sensitive and crucial component. Any phone can use liquid screen protectors, which don’t add extra bulk to your pocket or bag and don’t interfere with wireless charging. Finally, pick a first-party wireless charger or one of comparable quality for optimum compatibility. In general, the better the charger, the more likely it is to connect through thicker cases.
