setTimeout running in background for Android (iPhone?)

You must Login before you can answer or comment on any questions.

I have an app that uses setTimeout every 30 seconds to update status information.

It appears in Android to continue running after I go to home screen. How can I slow the setTimeout down when running in background (and vice-versa) to reduce load?

Also: I can't tell but does anyone know if setTimeout runs in the background for backgrounded iPhone apps?

A few thoughts:

I have my Android app exit when I go to the home screen. You do that by: 

mainWindow = Ti.UI.createWindow({
    exitOnClose: 'true'
});
on the main window. If you did this then you would know that timer is not running on home screen since app is not running.

For my iphone app, I have: 

Ti.App.addEventListener('resume', appResumeCB);
The function appResumeCB gets called when the iPhone app exits background mode (ie returns to active). Maybe there is another event for entering background mode.
