    A professor tested antenna's (not including design flaws) in 37 phones for making phone calls (GSM900 band, best band for phone coverage in my country). The test was done using the international standard for testing antenna's.

    Guess we all should be using the Dora Phone Easy. I am heading to Amazon now.

    Way too many variables to get an accurate test.

    I do believe the s5 was better than the s6 and any iPhone I ever had

    So much for antennagate - iPhone 4 is the highest ranking iPhone on there!

    Unfortunately, it's out of stock (most likeLy due to high demand from excellent antenna ratings).

    Well, it's your lucky day! The LG A250 IS still in stock. Grab it while it's hot:

    I would like to k ow the "real world" difference between -98 dBM and -93 dBm.

    Well it could be big, since 3 dBM difference means double.

    I don't understand that table, since to my understanding closer to zero dBM value is better? For example if you put iPhone to field test mode it shows you dBM instead of dots...

    I read that Doro is worst, Lumia 925 is best, iPhone 5 best of iPhones.

    Am i right?

    Could be...
    Also, 2% milk has DOUBLE (ZOMG) the fat of 1% milk....
    ...put another way, 1% milk is 99% fat free and 2% milk is 98% fat free. :-/

    Wasn't the antenna one of the hardware improvements that Apple made from the 4 to the 4S? That would support that the lower dBM is better.

    Nope. Dora phone is hand-down the best.

    "The numbers don’t follow a scale that makes much sense to normal people, but the lower the number (in other words, the more negative) the worse the signal, and the higher the number (less negative) the better.

    • Anything above -80 is good, and would be considered full bars
    • Anything below -110 is bad, and would be considered few bars
    For example, a signal number of -105 is considerably worse than a signal of -70. You’ll generally find that anything approaching -105 or lower is fairly bad reception, while anything above -80 is usually good, and if you tap the number signal it’s usually shown as full bars. The full range of the signal numbers extends from -40 to -120, with -130 being a nearly impossible number to see because it means no reception, and -40 would be about the strength you’d get being right alongside a cell tower. Technically, the number goes all the way to -140, but you will almost never see that because it basically means there is no signal to speak of, and most users will see -120 or -130 before it switches over to the “No Service” indicator instead."

    And now Doro is sold out because people read chart wrong way... :D

    If only the keys were in black, you know pink is too girly, I'd buy it in a heartbeat :D

    Here we go, derailing the thread with the whole "pink is girly" bandwagon again. ;)

    This doesn't surprise me one bit. iPhones have very mediocre antennas and have always given me a weak signal. Sure if you're near mast towers you'll get a full complement of dots but generally I see two dots. The iPhone 5 was the worst of the bunch for signal strength.

    Are you sure? Isn't iPhone 5 second best in this test?

    Second worst, whatever that means.

    yeah, it doesn't make sense. The lower the dbm, the worse the signal.

    In my own numerous experiments, my iphone 5s (yes, I still keep it) always has a lower dbm than my iphone 6s's

    No, closer to zero dBm means better signal strength.

    I have ZERO knowledge of antenna strength, ZILCH, but the way that chart has organized the data postulates that the phones at the bottom perform the worst and the phones at the top perform the best.

    Right, that's why the chart doesn't make sense.

    A phone with a -88 dBm is receiving a better signal than one displaying a -98.88 dBm.

    My iPhones are setup to where I can tap the upper left corner back and forth to display bars or dBm.

    Well it got a 'G' rating for signal strength so that's pretty crap in my book. It had easily the worst reception of any phone I've owned and I regularly had no signal whatsoever.
