Smart phone power consumption cut by more than 70 percent

-- This new solution is particularly valuable in developing countries because it provides significantly more effective Internet access to a much larger number of people. At the moment, only a small percent can access the Internet from a wired connection, but 90 percent of the African population lives in areas with mobile phone network coverage. Mobile phone usage is increasing rapidly, however the use of mobile Internet services is hindered by users not having access to the power grid to recharge their phones," says Professor Jukka Manner from Aalto University.

The case study conducted at Aalto University examined Internet usage in three East African countries: Tanzania, Uganda and Kenya. Researchers developed energy-saving solutions for smart phones that could be easily deployed across a mobile network and in particular in areas without reliable sources of electricity. In addition to the new, optimized proxy solution, the researchers found that the power consumption of smart phones could also be significantly reduced by mobile optimized websites, HTTP compression and more efficient use of data caching.

The study was published at the scientific conference Africomm 2011. The research began in the Future Internet research program of TIVIT and funded by Tekes -- the Finnish Funding Agency for Technology and Innovation. The work has been continued in the ECEWA project funded by Tekes, with partners from European Communications Engineering Ltd, Efore Plc, Ericsson, Aalto University and Tampere University of Technology.
