Is there a app to keep my phone from 3g to 4g?
I'm on the fringe of 4G service and it seems the battery drains faster when the phone keeps switching back and forth.
Phone info is the app... After installing, open, hit device info, scroll down to the bottom, and select CDMA/GSM PRL AUTO
that's 3g,when you want 4 G just go back to the one above it.
That isn't the case with my Razr, or S3.Once on 3g it stays until you go into the app and select lte/cdma again... I've kept my phone on 3g for weeks at a time.. Reboot and battery swaps daily don't affect my devices.

I have been sticking to 3g lately even though I have awesome 4 g coverage in my area. My battery has been reaping the benefits. I just turn on 4g if I need to download something.
Since we were in a 3G area when the ICS update happened, I installed LTE OnOff and switched to 3G-only.
Later, we traveled to a 4G area. I had a great deal of difficulty switching back to 4G. After running the app over and over, and repeatedly powering down the phone and pulling the battery, it FINALLY returned to LTE/CDMA/EvDo. I don't plan to use the app again. I'll let it continue to search for 4G service.
For the last two weeks, we have been back in 3G-only areas again. I have noticed no difference in battery life from when we had the phone set to 3G-only.
