How many people leave phone on 4g?

I always keep it on. Almost all of South Florida gets LTE, so I don't have any of the battery problems from switching between 3g and 4g. I also get better speeds on LTE than from my wifi connection. I use wifi whenever I can, but I haven't noticed that it's that much better on battery usage than 4g is. Display always takes up the lion's share of the battery use, and I keep it around 30% (30% brightness, not battery use. Display usually takes up around 80% of my battery). That's really my only complaint with the TB; the battery is too small, and the screen/display eats tons of battery while not being nearly as bright and clear as some other phones (cough, cough, Droid Charge), but all in all I think it's a great phone.
 
4G is on all the time for me and some days I have battery all day and some times I have to charge it in the middle of the day based on my usage.
 
I have 4g on all the time. I never seem to have a problem with going back and forth between 3g and 4g. I work for a dying wireless company and spend most of my work day waiting for a call to come in so I constantly use my phone and I am always connected to my charger. My phone is so much faster than our home WiFi that I would rather be on my phone than PC. If I use my laptop I connect to the internet through the mobile hotspot. Once again the phone's hotspot is much faster than our WiFi. I am irritated by battery life on the TB but have learned to keep some form of charger around at all times. After 3 months I am still amazed by my TB and 4g so I deal with the battery, which really seems to be drained by the display not the connection. ( I'm not the decision maker on my home WiFi. Otherwise I would definitely be looking fora new provider.)
