A device applies a new setting on its next wake, not immediately. In Deep Sleep both radios are off, so nothing can reach it until its timer fires.

Settings

Stay-awake is on. This drains the battery fast and makes the test numbers meaningless. Switch back before measuring.

Actions

Wake now works only on the Sleep arm. A screenshot is a low-resolution proof of what the app drew and adds about 35 seconds to the awake time.

The server time and the device clock will not match. The device clock runs fast while the screen sleeps, which is why both are recorded.

Awake time is measured by the server from the first to the last message of each wake. It is the number that decides this test: time awake costs far more battery than updating the picture.
