This article describes the problems delivering high power and high quality audio in music-enabled mobile phones, and how a supercapacitor can overcome them. This same supercapacitor can also enable high-power LED Flash photography without compromising the handset's thin profile.

Supercapacitors bridge the power gap between batteries and conventional capacitors, delivering higher power bursts than batteries and storing more energy than capacitors. Supercapacitors provide the power bursts needed for peak power events, then recharge from a battery. Benefits include improved talk time, longer battery life, a brighter flash and better audio. Designers also save space and cost because they can size the battery and power circuitry to cover average power consumption rather than peak loads.
