Power analysis is provided by the VTune Amplifier for Systems only. To analyze applications on Linux* target systems, run the CPU Sleep States or CPU Frequency analysis types from the VTune Amplifier GUI or CLI installed on the Linux or Windows* host. To analyze applications on Android* devices, use the Intel Energy Profiler (SoCWatch/WuWatch) to run the analysis directly on the device. You can view collected data either in the text-only mode on the device or import and view the data in the VTune Amplifier GUI nstalled on the host system.
