**Start the app and measure what you want to measure
**If you force-stop the app, wait a few seconds before starting the app to let the device settle
**If you're testing code that waits for gecko initialization (e.g. page loads ) and need to force-stop the app before measuring, make sure to 1) load a page and 2) wait 15 seconds before force-stopping the app<sup>6</sup>
