I have to say mine is running as smooth as silk now. Before I had all the 4g drops even though I live in a 4g area. Works great now, I have it set to go to wifi at home because my 4g is for some reason quite poor at home on the verge of 3g. I guess that is why I had all the drops. Speed is good now and I love my bionic. Battery about the same. I charge it every night on my dock and lasts pretty much all day.
