Wireless charging has revolutionized the way we keep our devices powered up throughout the day. Gone are the days of dealing with tangled cords and lost charging cables. With wireless charging, you can simply place your phone on a charging pad and let the magic happen. But, if you’re a Samsung A21 user, you might be wondering how to turn on wireless charging on your device. Worry not, dear reader, for we’ve got you covered.
What is Wireless Charging?
Before we dive into the nitty-gritty of enabling wireless charging on your Samsung A21, let’s take a quick look at what wireless charging is and how it works. Wireless charging, also known as inductive charging, is a technology that allows you to charge your device without plugging it into a power outlet. It works by using an electromagnetic field to transfer energy between a transmitter (the charging pad) and a receiver (your phone).
When you place your phone on a wireless charging pad, the transmitter coil in the pad generates an electromagnetic field. The receiver coil in your phone detects this field and converts it into an electric current, which is then used to charge your battery. It’s a convenient, hassle-free way to keep your device powered up, and it’s becoming increasingly popular in modern smartphones.

What is Wireless Charging?
Wireless charging, also known as inductive charging, is a technology that allows you to charge your device without the need for a physical connection to a power source. It uses an electromagnetic field to transfer energy between a transmitter (the charging base) and a receiver (your Samsung A21). This means you can simply place your phone on a wireless charging pad and it will start charging without the need for cables or adapters.
The technology behind wireless charging is based on the principle of electromagnetic induction, where an electromagnetic field is used to transfer energy between two objects. In the case of wireless charging, the transmitter (the charging base) contains a coil that generates an electromagnetic field, which induces an electromotive force (EMF) in the receiver (your phone). This EMF is then converted into electrical energy, which is used to charge your phone’s battery.
How Do I Turn On Wireless Charging on My Samsung A21?
To turn on wireless charging on your Samsung A21, you’ll need to make sure that wireless charging is enabled in your phone’s settings. To do this, go to the Settings app, then select “Connections”, and finally select “Wireless Power Sharing”. From there, toggle the switch next to “Wireless Power Sharing” to the “On” position. This will enable wireless charging on your phone.
Once you’ve enabled wireless charging, you can place your phone on a wireless charging pad to start charging. Make sure the charging pad is properly plugged in and that your phone is aligned correctly on the pad. You should see a notification on your phone that it’s charging wirelessly.
Is Wireless Charging Safe for My Samsung A21?
Wireless charging is a safe and reliable way to charge your Samsung A21. The technology has been extensively tested and certified by various organizations, including the International Electrotechnical Commission (IEC) and the Society of Automotive Engineers (SAE). Wireless charging pads and phones that support wireless charging are designed to meet strict safety standards, including regulations related to electromagnetic interference, electrical safety, and thermal performance.
In addition, wireless charging is designed to prevent overheating, electrical shock, and other safety hazards. The charging pad and your phone are designed to communicate with each other to prevent excessive heat buildup, and the charging process is automatically stopped if a problem is detected.
How Fast is Wireless Charging Compared to Wired Charging?
Wireless charging is generally slower than wired charging, but the speed difference is not significant. The speed of wireless charging depends on the type of charging technology used and the power output of the charging pad. Most wireless charging pads support fast charging, which can charge your phone up to 15 watts.
In comparison, wired charging can support faster charging speeds, up to 25 watts or more, depending on the charger and the phone. However, wireless charging has the convenience of not having to deal with cables or adapters, making it a popular choice for many users.
Can I Use Any Wireless Charging Pad with My Samsung A21?
Not all wireless charging pads are compatible with your Samsung A21. While most wireless charging pads use the Qi (pronounced “chee”) standard, which is the most widely used wireless charging standard, some pads may not be optimized for your phone’s specific charging requirements.
To ensure compatibility, it’s recommended to use a wireless charging pad that is specifically designed for your Samsung A21 or one that is certified by the Qi organization. You can check the manufacturer’s website or the packaging of the charging pad to ensure compatibility.
How Do I Know if My Samsung A21 is Charging Wirelessly?
When you place your Samsung A21 on a wireless charging pad, you’ll know it’s charging wirelessly if you see a notification on your phone that it’s charging. You may also see a charging animation on your phone’s screen or a flashing light on the charging pad.
Additionally, you can check your phone’s battery settings to see the charging status. If your phone is charging wirelessly, it will show “Wireless Charging” or “Qi Charging” as the charging method.
Can I Use Wireless Charging with a Case or Cover on My Samsung A21?
You can use wireless charging with a case or cover on your Samsung A21, but there are some limitations. The case or cover must be thin enough to allow the electromagnetic field to pass through and must not contain any metal or other materials that could interfere with the charging process.
In general, most phone cases and covers are designed to work with wireless charging, but it’s always a good idea to check the manufacturer’s specifications to ensure compatibility. If you’re unsure, you can try removing the case or cover to see if it affects wireless charging performance.
