E-mail, phone, Web browsing, text messaging and even a 35-key QWERTY keyboard are part of the Blackberry mystique. Intelligent light sensing technology automatically optimizes the screen lighting levels for indoor and outdoor viewing of the 320 × 240 pixel LCD color screen. In addition to the lighting technology, the unit has a built-in speakerphone for hands-free usage where an audio power amplifier provides mono and stereo listening. Like other high-functionality portable products, the Blackberry uses several dc-to-dc converters. Efficient design allows the removable/rechargeable Lithium cell to provide up to 16 days standby time and four hours talk time.
