Energy profiling for Android

[Luis_C_]

I am working on a research project in which I need to measure the energy consumption of Android apps.

I need a device that runs Android, or that can connect with an Android mobile phone, and that is able to collect precise power data.

I am not looking for power estimations.

I have seen here several software tools but I could not understand which hardware should I have in my solution.

Do you have any ideas?

If you are a developer measuring power consumption in order to improve the design of your own software, we have some information here that you might find useful: https://software.intel.com/en-us/android/articles/android-power-measurement-techniques

If you simply need an app to measure energy consumption of other apps, an internet search for "Android power consumption app" seems to yield info about some promising third-party solutions.
