Aalto University researchers have developed new ways to significantly reduce power consumption for smartphones, particularly in locations that do not have reliable sources of electricity.
The researchers created a network proxy that can be deployed across a mobile network and reduce the power consumption of 3G smartphones by up to 74 percent. The device is designed to enhance performance and limit power usage by acting as a middleman for mobile devices to connect to the Internet and handling the majority of the data transfer for smartphones.
"This new solution is particularly valuable in developing countries because it provides significantly more effective Internet access to a much larger number of people," says Aalto University professor Jukka Manner. "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."
The researchers also found that mobile optimized Web sites, HTTP compression, and more efficient use of data caching could serve as energy-saving solutions.
