You just need a 2G/3G toggle. Tasker would be a good solution, or perhaps Xposed framework with Gravitybox custom quick tiles.

I mean in mobile settings preferred mode should be always 2G for talking but when I switch data enable it should automatically select preferred mode 3G. So when I'm not using internet 2G should be selected what when I choose to use mobile data it should automatically select 3G (I happen to believe when 3g network is selected -even without data- consumes more battery and try to search for 3G signals which has no benefit for talking.)
Btw I tried to use tasker but android is not giving me permission to toggle 2g/3g network. shame
I'm rooted, is there any way to get permissions for toggleing between 2G/3G without getting a shortcut to settings page(every toggler just giving a short cut and in Tasker 2G/3G toogle is unselectable and red)
