"Restrict Background data" with Jelly Bean on tf300t ASUS tablet

Question

On my tf300t ASUS tablet (with wifi only) I tried to set "Restrict Background Data" following

Settings->Data Usage->three boxes in the upper right corner,

but there is no such option. I read on some forums that this option is only available with limited mobile data, but the option to set a limit is not available under Settings->Data Usage->three boxes in the upper right corner.

There is, however, an option under

Settings ->Developer Options -> Background process limit,

but I'm not sure about it. On my Gingerbread phone, background processes were disabled, and whenever I wanted to download an app, I had to enable it. With the Backround Process limit, however, downloading is possible (therefore, I'm not sure if this is the equivalent to Gingerbread's setting). Furthermore, I noticed that, after setting Background Process limit, every once in a while I get a message that some Asus process has been terminated. My question is: how would one disable background processes (no connections to wifi while screen off, ...) in order to save the battery?

Answer 1

You can check the background process limit box. Its the best way to limit your background processes and in a way save your battery. You can also use power saving mode if you have one....

Answer 2

On my HTC Wildfire (Buzz) running Android 4.0.4 I find the corresponding option in Settings→Data Usage, when I hit the "Menu" button. This brings up A sub-menu with 4 checkboxes: Data-Roaming, Background Data, Show WiFi, Linear Scale. Tapping the "Background data" option I am informed:

background data only can be limited if you defined an overall limit for mobile data

(well, I have not defined any limit there yet). So that should be where background data can be restricted.
