An inductive power transmitter is provided that includes a power transmitting coil which includes transmission circuitry coupled to the power transmitting coil. The inductive power transmitter is configured to produce an inductive power transfer (IPT) signal having an IPT power so that the power transmitting coil generates an IPT field to transfer wireless power to a power receiving coil of an inductive power receiver. The inductive power transmitter includes detection circuitry coupled to the transmission circuitry and is configured to detect one or more indications of a magnetic field strength of a leakage IPT field. The inductive power transmitter includes control circuitry configured to control the transmission circuitry while the transmission circuitry is increasing the IPT power towards a charge level sufficient to charge a battery associated with the inductive power receiver at a target charge rate.

An input/output interface for an electronic device receives touch and/or force input and, additionally provides haptic output to a user. In particular the input/output interface is operated in conjunction with an input surface and includes at least one input sensor and at least one haptic output element. In typical embodiments, the input sensor is ground-shifted to prevent damage to the input sensor when the haptic output element is driven.
