Technology
With the rapidly
growing popularity of smartphones, demand for reducing charging frequency is
growing among consumers. A research team led by Keio University professor Hirotada Kuroda developed a technology data processing technology that can reduce the
power consumption of a smartphone by up to 10%. The new technology is for
wireless connection between the CPU and the memory. Data are traded between
them using the electric field and the magnetic field created when an electric
signal is transmitted, making it possible to reduce voltage to operate the
memory. The research team confirmed that the wireless data processing can
decrease the power consumption by 90% as compared with the existing wired data
processing. In addition to the ability to reduce power consumption, the new
technology has more than three times faster data processing speed than the existing
technology.
Fujitsu developed a
small amplifier to be incorporated in a smartphone. Using the technology that allows
for the management of optimal voltage depending on usage, the company
successfully reduced the power consumption by 30%. An amplifier is vital to
intensify the output of electric waves that contain voice and data and deliver
them to the base station, and consumes about 10% of power consumed by a
smartphone. MM Research Institute, a research firm on the IT market, reported
that more than 50% of smartphone users were dissatisfied with the waiting time
before his or her smartphone finishes charging. A smartphone trades 10-20 times
more data than a mobile phone. The race to launch the technology to reduce
charging frequency will supposedly heat up.
