Common Causes for a Noisy Wireless Charger

Before you toss your charger, let's figure out what’s causing the racket. Most of the time, the issue is simple and easy to fix. The noise you're hearing usually comes down to one of a few culprits.

Coil Whine: The High-Pitched Squeal

The most common reason a wireless charger is making noise is something called "coil whine." Inside your charger and phone are coils of wire that transfer power via a magnetic field. Sometimes, these components vibrate at a high frequency, creating an audible buzzing or whining sound. It's usually harmless but definitely irritating, especially in a quiet room.

The Cooling Fan

More powerful, fast-charging wireless pads generate more heat. To manage this, some models include a small, built-in fan. You might hear a gentle whirring sound, which is perfectly normal. However, if that whirring becomes a loud or grinding noise, dust could be the problem. A good clean might be all it needs. When you're looking for robust gear, always check the specs on quality gaming accessories to see if they include active cooling.

Misalignment and Obstructions

Wireless charging relies on precise alignment between the coils in the charger and your device. If your phone is slightly off-centre, the charger might work harder to establish a connection, causing its components to vibrate and make noise. A thick phone case or a pop socket can also create a gap that leads to inefficient charging and... you guessed it... more noise.

How to Fix a Wireless Charger Making Noise

Ready to silence the buzz? Here are a few simple steps you can take to fix your noisy wireless charger. 🔧

1. Reposition Your Phone: This is the easiest fix. Lift your phone and place it back down, making sure it’s centred on the charging pad. Many phones give a little buzz or on-screen animation to confirm charging has started correctly.
2. Remove the Case: Try charging your phone without its case. If the noise disappears, your case is likely too thick or contains metal parts that interfere with the magnetic field.
3. Check Your Power Source: Are you using the original power adapter and cable? Plugging the charger into a laptop's USB port or a cheap wall adapter might not provide enough stable power, leading to coil whine.
4. Give It a Clean: If your charger has a fan, unplug it and use a can of compressed air to gently blow out any dust from the vents.

When It’s Time for an Upgrade

If you’ve tried all the fixes and your charger is still buzzing like a bee in a can, it might be time for a replacement. Persistent noise, especially if it’s getting louder, could indicate a failing component. Slow charging speeds or frequent disconnects are other signs that your old charger is on its last legs.
