    Anandtech did a review awhile back:
    http://www.anandtech.com/show/3794/the-iphone-4-review/2

    Showing the following picture (below)

    Did anyone know where I could find the exact ranges under iOS 9.x?

    E.g., looking for the following (NOTE this is what I am looking for, it is not correct-serves as an example only)

    0 bar = -120 or lower
    1 bar = -106 to -119
    2 bars = -100 to -105
    3 bars = -86 to -99
    4 bars = -85 to -81
    5 bars = -80 to -75

    not seen the above published chart but you can use field test mode to see for yourself. I observed the following the other day when testing.
    9.2.1. Cell strength.
    -100 was 3 dots
    -92 was 4 dots

    Here is what I have confirmed/seen so far:
    -116 and lower (1 bar) ... not sure where it bottoms out as this is as low as I have been able to see it
    -115 is two bars .. not sure where it goes to three bars (it looks like -105) or around there but have not been able to confirm

    Why bother to leave the bars? Just change it to show dBm and you'll always have a more accurate reading of signal.

    Yes I use the numbers, I just want to know what the numbers equate to in bars so if i see -115 for example I know that is two bars.

    Just tap the numbers and it will turn to bars, and vice versa (once its in permanent field test mode)

    Yep - I am looking for the ranges in dbm for each level (1, 2, 3, 4, 5) bars.
