Digital radio uses a more complicated process than analogue radio. It involves receiving the signals and then decoding them through a digital encoder into the sound samples that are then streamed back. This all takes power and, seeing that this does not happen in analogue radio, it drains batteries faster. Basically there is much more electronic jigory-pokery going on! Also there is much more information coming into the radio which has to be decoded and presented - e.g. scrolling text about the station etc.
