Close connection after XX minutes for mobile views

[barrymossel]

Currently there is a setting to close connection to the server after 5 minutes of being hidden. The 5 minutes seem quite long for mobile views, especially when a tab with live camera was open and it keeps streaming.

Would it be possible to have an alternative timing for this option for mobile views as I believe mobile usage is different compared to desktop usage. I guess if you use a mobile app/browser you quickly check something or toggle a light, close browser/app and don't go back for quite some time. Then 5 minutes will be necessary.

Also mobile is more often used with (a) mobile data (plan), which can be limited, opposed to desktop usage.
