Turn off things like GPS, Bluetooth and uninstall apps you don't need. Then you may get more time.
As to the apps to the SD CARD that's up to the app's author to allow or not.
my ph gets switched of of its own though there is still charge in it n also when i download apps it shows cannot be stored on usb or sd card.
also d battery life is really less. it requires atleast two tyms recharge in a day
