An electrical device has a display and a battery which has a varying electrical condition. The display typically displays information to be read by the user of the device. In response to a low battery detection, the information being displayed may be interrupted with information indicating the battery is low. The timing of the interruption increases as the battery nears depletion thereby giving user an indication of the remaining battery capacity. The variation in timing includes either increasing the duty cycle of the periodic interruption, decreasing the period of the interruption, or both. The electrical device may include a wrist watch paging receiver with a message display and a clock with time of day and date functions.
