3G&2G choosing this setting means the phone will operate on 3G but when it can't it will switch to 2G.
Californiablackberry is right 2G uses less battery.
Also switch off your GPS if you not using it. This will save you battery life.
If you are still on os 7.0 better to switch to 7.1 it is more battery efficient.
Also having wifi, bluetooth and nfc on for no apparent reason will also sap your battery.
And switch off "roaming" as well if you not travelling overseas.
