A new application has been developed which can help check the power being consumed by the application loaded on SMARTPHONES. Students and professors at university of Michigan have developed a application called ‘POWER TUTOR’ for the android Smartphone.
Lide zang, a developer of product and a doctoral student in department of electrical engineering and computer science, said:”Today, we expect our phone to realize more and more functions, and we also expect their battery to last. Power Tutor will help make that possible.”
Power Tutor can show in real time how four different phone components use power: the screen, the network interface, the processor, and the global positioning system receiver.
To create the application researchers disassembled their phones and installed electrical current meters. Then they determine the relation between the phone’s internal state (how bright is the screen is, for example) and the actual power consumption. That allowed them to produce a software model capable of estimating the power use of any program the phone is running with less than 5% error.
