What is "idle mode"?

Idle mode is a state where the phone has no network connectivity and apps are temporarily suspended. Idle mode gets triggered by one of two ways: an asleep, still, unplugged phone (Doze mode), and when an app has not been opened in a significant amount of time (App Standby Mode). During idle mode via Doze, the phone will wake up periodically for a short amount of time, allowing apps to run and use network connectivity. Using several different methods outlined below, it is possible to wake apps up during idle mode outside of these maintenance windows.

Time to enter Doze mode

1 hour of being still after the screen turns off.

Time to enter App Standby mode

TBD

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
