I use my 4g every chance I get, I am in Chicago so I get pretty good 4g coverage everywhere except my apartment.
I'm with you, I never turn my wifi on always leave 4G on 24 x7 Luckily where I live here in Tampa FL we get pretty good 4G right around 3Mbps to over 6Mbps
Bought an extra battery off ebay ($5.50) I'm good to go all day.
