I stopped caring to be honest. I used to test my speed all the time back when I just got my OG Evo. But over time, I've grown to know where the speeds suck and where they are good. There is basically a 2-3 mile stretch of my commute each day where the data speeds suck. Everywhere else is fast enough for me.
That being said, I am in 4G half the time these days as I just leave it on. Unlike the OG Evo, I don't get an annoying icon reminding me that I have 4G left on. The extended battery also helps me not care so much about having 4G on.
These days, if I am running speedtest, it's because there's a problem, and I want to identify it as a network issue.
