An electronic device comprises a first component susceptible to a wearout effect, operation of which first component depends on an operating parameter, and a second component having an on-state and an off-state. The electronic device further comprises a time estimator for updating an estimate of an accumulated time the second component was in the on-state; and a controller for controlling the operating parameter on the basis of the accumulated time estimate so as to respond to the expected wearout effect. The first component and the second component may be the same, or the first component may have an on-state correlated to the on-state of the second component. The operating parameter may, for example, be a level or amplitude or correction value of one of the following: a voltage applied at the first component, an electric current fed to the first component, and a power provided to the first component. A method of operating such an electronic device is also disclosed.
