It’s important to note that wireless charging is generally less efficient than wired charging due to energy loss as heat in both the charger and the phone, a factor that becomes noticeable during long charging sessions. If FOD identifies an item that could heat up and pose a risk, the charger immediately stops operation, protecting both the device and the user.

Conversely, when a second coil is placed within this magnetic field, an electric current is induced within it. To mitigate this, Samsung incorporates alignment indicators on the charger and optimizes the internal coil geometry to create a larger effective charging area.
Alignment and Foreign Object Detection While the basic principle is straightforward, effective implementation requires sophisticated engineering to ensure efficiency and safety. Furthermore, the system utilizes Foreign Object Detection (FOD), a safety feature that monitors the charging area for metallic objects such as keys, coins, or credit cards.
