In this case study from researchers at Hewlett-Packard, the power characteristics of a handheld computer were evaluated. The purpose of the study was to shed some light on how battery operated handhelds consume power under representative workloads, possibly leading to more efficient "low-power design and power management." Experimental procedures and results are presented for extensive battery lifetime analyses over several benchmarks. The authors state that this research can be used as a starting point for hardware and software designers of handheld devices to more effectively gauge battery performance.
