I remember my friend had a lot of trouble with his S3 trying to get it into edge it would only stay on LTE mode, I'm wondering if this phone is also difficult to get into edge or impossible because that could be a deal breaker for me.

Ok, so let's look at options. This all depends on what firmware you will be on. At this point, more than likely you will be on MF3. If you found a phone (assuming it is an AT&T S4) on MDL, you could use the phones service menu options to drop the connection to "edge" just about full time. But, like I said, that is assuming it will be an AT&T phone with MDL firmware. Unlikely at this point.
The thing is, these phones are set up to handle LTE connections in a very efficient manner. I don't think you will see very much (if any) difference in battery drain using GTalk on LTE versus Edge. What will drain your batter is if you have a weak connection on either. The phone will use much more battery power trying to establish and maintain a connection if it is a weak signal than it will if the connection signal is strong regardless of the connection type. People that complain about battery drain with LTE are used to using older phones that actually did eat through battery with LTE. Also, in many of those cases the phone was struggling to maintain a strong connection or was constantly switching between connections, which drained the battery much quicker.
I would take graydiggy's advice and focus on other aspects of the phones battery use for power savings. Figure out which type of connection is strongest in the area you will be using the phone in and stick to that connection type. There are apps that will help you see this or you can look in the settings on the phone to see which network it stays connected to the most. Good luck.

Make sure you read and understand the "PINNED" threads in the "General" and "Q & A" sections of the AT&T S4 forum BEFORE you ask for help. Use the forum's "search" function to find posts with additional information. You should not expect others to help you if you haven't tried to help yourself first. Also, read, understand, and follow the "XDA" rules.
