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
- Idle
- 3G modem
- Idle
- Disconnected
- Active
- Similar to WLAN tests
- Bluetooth
- Idle
- Disconnected
- Active
- Similar to WLAN tests
- Additional INFO required: AP model
- WLAN
- Display tests
- Test idle with
- full screen brightness
- half brightness
- Test idle with
- 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
- Active
- Peak and average consumption
- Idle
- Does the audio chip power off
[1] Longer tests can be considered if we have certain applications that have much longer cycles of periodic activity
