I have a quick question about Field Test Mode and SpeedTest results. I have Verizon and always have reliable speeds and good reception where I live/work/play. I never drop calls, never drop off of LTE, and regularly get speeds of 10-30 megs down and 5-10 megs up. That being said, I keep my iPhone 7 in Field Test Mode, as I prefer decibel values to arbitrary dots. I've read the values and have read that -40 is about ideal reception, -60 to -80 is good, and that -80 to -120 is bad with anything above that having no reception. However, despite having good reception and data speeds, my phone almost always reads numbers of -100 to -115. What gives? Worse reception with better speeds (in my basement office). Better reception with worse speeds (in a corner classroom).
