FaST Team:
• What are the energy saving benefits:o The convergence of consumer products into one
device such as a Smart phones or tablets vs. single-function products, and
o how are they changing the consumptive
behavior of humans?
The Project
• To investigate the battery consumption of smartphones and tablets using different applications.
• To compare popular applications to relevant stand-alone devices in the market today (portable gaming, scanning, music players, etc. )
• To compare applications and smartphone devices among each other
