Energy consumption of smartphone components

I'm looking for a list of all the components and their power drainage on an up-to-date smart phone.

  • Accelerometer, gyroscope, magnetometer, etc.
  • Display
  • WiFi
  • Bluetooth
  • GPS
  • CPU
  • Camera
  • Microphone
  • etc.

Preferably in mA so it can be easily compared to the battery's capacity (usually specified in mAh).

The Sensor's power is actually available via the SDK and can also easily figured out for most devices on AndroidFragmentation. However what I'm looking for is comparable data for the other hardware components to consider their efficency.

Bonus: Will a request for less frequent updates of a Sensor decrease energy consumption of the Sensor, as it returns only one value for getPower()?

There are a couple of detailed studies that I am able to find on this.

  1. A study from the USENIX meeting in 2010 which studies various components of a smartphone (except the camera)
  2. Another study from the Hotmobile mobile computing workshop 2013 that has more information on cameras and displays.

Reference 1 especially seems a great starting point.
