A DIY power monitor to compare mobile energy consumption in situ

Many current smartphones need to be recharged every day despite only average usage. This problem is intensified when phones need to track their location on a continuous basis. We provide a yet unavailable platform for accurately measuring the energy consumption of different hardware/software solutions comparing up to three variants in a mobile setting. We show that the accuracy of our system is similar to a fixed, commercial system but is especially useful to evaluate and optimize technology and algorithms that require the phone to be used on the go.
