If like me you can only get the 4G LTE reception when you are in the city or you are just on the outskirts of the 4G LTE zone then you will notice that your phone is constantly flipping between 3G and 4G LTE thus using lots of battery.
To Disable / Re-enable 4G LTE on your iPhone 5 simply follow the instructions below.
Tap on Settings
Go to General
The tap onto Mobile Data or Cellular Depending where you are in the world.
Then simpy move the "Enable LTE" slider to either on or off.
