The technology dynamically negotiates the power transfer rate between the charger and the device, typically operating at 5W, 9W, or 15W depending on the specific model of the phone and charger. Higher wattage models, such as the 15W versions, require compatible Samsung phones like the Galaxy S21 or S23 series to achieve the fastest speeds, as the phone itself regulates the incoming power to match its battery management system.

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. This compliance ensures interoperability, meaning a Samsung phone can charge on a Qi-certified charger from another brand, and vice versa.
For optimal results, it is recommended to use the device without a bulky case or to utilize cases specifically designed to be charging-friendly. To mitigate this, Samsung incorporates alignment indicators on the charger and optimizes the internal coil geometry to create a larger effective charging area.
