Typical tests should last 30-60s to encapsulate most low-level periodic wakeups[1]. All the tests are to be done on battery (obviously)

Idle tests

  • Idle after boot
    • Boot up default install, wait a minute or so to let all applets to settle down (e.g. WLAN) and then measure (full brightness and half brightness)
  • Idle after resume from suspend
    • Same as idle after boot
  • Idle after resume from hibernate
    • Same as idle after boot
  • Separate testing for server, desktop and UNR install
    • server is expected to consume the least and will supply the baseline for a specific HW platform

HW-specific testing

  • Radio tests
    • WLAN
      • Idle
        • Connect to AP, do network activity for a while and then idle
        • Does the WLAN device switch to low-power mode?
      • Disconnected
        • Disconnected from AP using applet and make sure we go back to base consumption (radio being turned off correctly)
        • Use rfkill switch and make sure radio is being turned off correctly
      • Active
        • Measure peak consumption and average consumption with activity over WLAN
    • 3G modem
      • Idle
      • Disconnected
      • Active
        • Similar to WLAN tests
    • Bluetooth
      • Idle
      • Disconnected
      • Active
        • Similar to WLAN tests
    • Additional INFO required: AP model
  • Display tests
    • Test idle with
      • full screen brightness
      • half brightness
  • Backlight measurements
    • Figure out usecase for backlight measurements (Useful for figuring out how agressive ALS should be)

Usecase testing

  • Browsing over WLAN
    • Preconfigured with flash plugin at full brightness
    • 5-10 tabs loading a pre-cached set of webpages
      • Loading live sites changes the numbers (due to flash content and changing network conditions)
    • separate tests for browsing over 3G?
  • Music streaming over WLAN
    • Exercises the audio chip, important for ARM platforms that might use a separate DSP processor
    • Active
      • Peak and average consumption
    • Idle
      • Does the audio chip power off
  • Movie playback (longer test with DPMS disabled)
    • Run from DVD and from disk
    • Disk test should use some standard encoding formats (.mpg, .avi with H.264, ogg-theora, etc.)
  • Webcam
  • Ethernet

[1] Longer tests can be considered if we have certain applications that have much longer cycles of periodic activity
