Understanding Why Wireless Charger Overheating Occurs

Before we jump into solving wireless charger overheating, it helps to know the cause. Wireless charging, or inductive charging, works by creating a magnetic field between two copper coils—one in the charger and one in your phone. This process isn't 100% efficient, and some energy is always lost as heat. A little warmth is normal, but excessive heat is a red flag.

The most common culprits include:

• Poor Alignment: If the coils aren't lined up perfectly, the charger has to work harder, generating more heat.
• Phone Cases: A thick case, especially one with metal parts or a pop socket, can interfere with the magnetic field.
• Low-Quality Chargers: Cheaper models often lack the advanced safety features and temperature control of premium units, making them a risky part of your setup alongside other essential gaming accessories.
• Intensive Use: Gaming or streaming video while charging puts a double strain on your device, causing both the battery and the charger to heat up.

Practical Steps to Keep Things Cool

Solving this issue is often easier than you think. By making a few small adjustments, you can significantly reduce the heat and protect your phone's long-term battery health. Here are some simple, effective fixes you can try right now.

Tweak Your Charging Habits 🔧

Start with the basics. Every time you place your phone on the pad, take a second to ensure it's centred. You'll often feel a slight magnetic pull or see a charging icon appear instantly when it's in the sweet spot.

Also, consider removing your phone case before charging, particularly if it's a rugged, multi-layered one. This simple step can make a huge difference in heat transfer and charging efficiency.

If these simple fixes don't completely solve the problem, it might be time to look at the hardware itself. You can explore our full range of chargers to see what modern options offer.

When to Upgrade to a Smarter Charger

If you've tried everything and your phone still gets alarmingly hot, the charger itself is likely the problem. Budget chargers often cut corners on critical components like thermal sensors and cooling systems. A high-quality charger isn't just about speed; it's about safety and reliability.
