Disable 4g

If you are having battery life problems with 4G there are other problems causing it.
 
I used an app called LTE on off on my razr and it helped. Live out in the sticks and the phone was constantly going back and forth trying to lock on from 1x to 4g. Don't know if it will work on the G2.
