MSM8660 Video Payback Power Measurement Procedure

1. After loading MSM build, load device QCN, place in airplane mode before measurements.
2. Insert SD card in the device
3. Push required files to the SD card (Make sure SD card is formatted if using for the first time)
4. Make sure the device is ON, and USB is connected when executing the steps given below
a. Make sure that SD card read-only lock is not on
b. adb push FILE_PATH /sdcard/ (for example: adb push C:\QTC88.mp3 /sdcard/)
c. If it is not able to write, change permissions as "chmod 777 /sdcard/"
5. Insert headset
6. Reboot the device
7. Connect USB to the device
8. Set Class D using batch file(classd.bat) - This step is only for 8660 Spartanized FFA
9. Disconnect USB
10. Make sure Display Timeout is set to 30 minutes
11. Play the video file under e.g. Main menu > Videos > select video(QTC48.mp4, QTC77.mp4 , or QTC88.mp4) to play
12. Set volume to 9/15
13. Start power measurement

Note:
1. SD card contribution should be subtracted for power measurement
2. Video test cases(QTC48, QTC77 and QTC88) are measured with LCD/BL ON with default setting values. LCD/BL power contribution should be subtracted after power measurement
3. To verify the FPS of the video, type command: adb shell setprop persist.debug.sf.statistics 1 or adb shell setprop persist.debug.sf.showfps 1 and the FPS will show in adb logcat (needs USB connected)
