It's normal for a wireless charger to feel warm during use, especially when your phone is running high-demand apps like navigation, video streaming, or games. Rest assured, the charger meets international safety standards, including EN 62368-1 and IEC 62368-1, and is safe to use.

Performance Compared to Apple's Official Chargers

Our magnetic wireless charger has been tested for charging speed and temperature performance and delivers results similar to Apple's original accessories. The warmth you feel isn't caused by the charger itself—it's how iPhones manage battery health during charging.

Common Reasons for Heat or Slower Charging

1.iPhone's Built-In Temperature Protection

iPhones automatically adjust charging speed if the device gets too hot or too cold. This is a safety feature designed to protect the battery and extend its lifespan. If your phone gets warm and pauses charging, that's completely normal and part of Apple's battery protection strategy.

2.Tips to Minimize Heat and Maximize Charging Speed

To reduce heat and improve charging performance, we recommend:

• Avoid using your phone heavily while charging, especially for GPS navigation, video calls, or games.

• Limit high-drain activities during charging. Power-hungry tasks can cause your phone to heat up, which may activate iOS thermal protection and slow or pause charging.

When your iPhone detects excessive power use and rising temperature, it prioritizes battery safety over charging speed. Following the tips above will help keep charging efficient and your battery protected.
