Mobile phone manufacturers are continually looking for ways of adding new features to their handsets in order to distinguish between competitors' products. But in adding new functions, the need to improve power management in the phone becomes essential as they strive to maintain the levels of battery standby time to which the modern consumer has become accustomed. This is crucial, since adding abilities such as multimedia audio, video, or gaming would invariably place a greater drain on the system battery; in order that the consumer not notice the effect, the onus is on the manufacturer to increase operating time so that the standby time appears equivalent to previous generation phones.
