Memory access

Here the consumption of memory access is measured by saving a file of one MB on different drives of the phone:

  • D: It is the drive used to store temporary files
  • E: Memory card (micro SD)
  • C: This drive is a flash memory also called phone memory

 

 

Experiment details

Description:

Power consumption for saving 1 MB on the phone

Place:

Indoor

Number of tests:

50

Notes:

During the measurements all the air interfaces (BT, WLAN and Cellular) are switched off.

 

The Figures below show the values of energy, time and power for saving the file respectively. As expected time, and therefore energy, is smaller when using the D drive.
