Sorry, I know I have seen threads about this but didn't pay too much attention since I didn't live or work in a 4G area. But today I look at my phone which I haven't used all day to this point and the battery is over half gone. Now I see 4g LTE on my status bar, so apparently my work is now in a 4g area. Since I am at work I don't have a ton of time to search, but can anyone update me with whether there is an app or solution to turning off 4g and saving battery? First know I am not a phone expert.. I don't "root" or anything, not even sure what that means, so I aplogize ahead of time for my ignorance! Thanks in advance.
