The correct alignment of the end devices is crucial for optimal charging via the wireless charging pad. To prevent heat build-up, end devices should lie flat on the charging pad, i.e. without being raised by the camera, for example. Find out where the wireless charger is located in your end device and align it exactly with the position of the hugo! It is also advisable to remove protective covers for optimum charging. There should be no metallic or electrically conductive objects between the end device and the wireless charger.
