Samsung Galaxy S3 - Battery Drains really fast on 4G-LTE, but not on 4G

[seadaily]

Where I work, I don't get an LTE signal, so my phone is always on 4g and the battery drains at a reasonable rate. When I get home though, I have a very strong LTE signal and my battery starts to drain at several percent an hour. One evening I went from ~50% to 15% in about 4 hours. Also, when I'm home, I tend to use my phone even less than at work.

I've tried all battery saving tips I could. I disabled pretty much all of the AT&T and Samsung apps that I could. I've only had the phone for about 2 weeks so I don't have much installed, and the only thing that is using sync is the gmail app. I don't use the standard email app because I have no use for it. All the battery monitoring I've done seems to show that the usage by the radio skyrockets when I get back into LTE land.

I realize that LTE uses more battery than 4G, but this seems a little ridiculous, especially since I would assume their should be some extra loss of battery from the phone constantly looking for LTE signal. Does anyone know of a solution to this?

sounds like the glitch that happens when you switch towers from LTE to something else to LTE.... there are threads in other forums discussing this and one more in this very forum. no response from att or samsung yet. when you talk to samsung about it they pretend like it just may be YOUR phone. but rest assured a ton of us are experiencing the same issue. temporary mickey mouse fix is just reset the phone when you get back home.
