Fresh install had the same dBm for B41 @ 114dBm, installing lollipop now to compare. And I agree it's really upsetting, I love this phone but I am not liking having to deal with these problems.
Well this is weird, Lollipop is showing roughly the same dBm, 114. There goes my theory, wtf. Something more serious going on then, maybe it's a tower issue idk.
