So I've never bothered to turn off 5G on my phones, until now. I decided to do this because I was having signal issues at my new office. Which in turn caused battery drain issues. So the first thing I noticed is, my data speeds increased at places where I had a weak signal. So it turns out a weak 5G signal is no comparison to a mediocre to strong LTE signal. My data speeds in general have improved overall. It also solved my battery drain issues. I haven't been tracking battery life, but I would say battery life has had an improvement even before the signal issues. So if you haven't ever bothered to turn off 5G, give it a try if your having signal issues, data speed issues, or even battery drain issues.
