In this article, we’ll delve into the possible reasons behind this issue and provide you with troubleshooting steps to get your S21 charging wirelessly again.
Understanding Wireless Charging
Before we dive into the troubleshooting process, it’s essential to understand how wireless charging works. Wireless charging, also known as inductive charging, uses electromagnetic fields to transfer energy between a transmitter (the charging pad) and a receiver (the phone). This technology is based on the principle of electromagnetic induction, where an alternating current (AC) flowing through a coil in the transmitter generates a magnetic field. When the receiver coil in the phone is placed within this magnetic field, an alternating current is induced, which is then converted into direct current (DC) to charge the phone’s battery.
Qi-Certified Accessories
To ensure compatibility and safety, the Qi (pronounced “chee”) wireless charging standard was developed. Qi-certified accessories, including charging pads and phones, have undergone rigorous testing to ensure they meet specific guidelines and safety standards. The Samsung Galaxy S21 series supports Qi wireless charging, making it compatible with a wide range of Qi-certified charging pads.
