Has anyone performed a test like this for the iPhone 6S?

    Very interesting. I'm not that pleased with the LTE/3G stability on my 5S..

    when i was using S6 i also noticed that it was slow to connect to a faster network when it was available, but i assumed it was the networks fault. Now i see it's the phone. All i can say that my 6S Plus connects to a faster network faster than S6.

    Hmmmm....I currently have a Note 5 and 6s+ and they both connect the same to faster networks. I often do speed tests Speedtest app using both WiFi and Cellular networks. They BOTH are very close to each other. Sometimes the N5 wins sometimes the 6s+ wins. This is real world testing from a person with both phones over time and different locations.
    Oh and with different carriers as well. I have accounts on TMO and Verizon.

    S6 Edge. I have no problem reaching 90Mbps on T-mobile network. And haven't had a dropped call yet. My signal strength is usually in the -70s dBm according to the Phoneinfo app.

    I've tested ATT/VZN/T-Mobile, currently on T-Mobile.

    With Verizon (when I was testing it, I was seeing -110 to -115 in buildings) and even outside only rarely did I ever see 4-5 bars.. A friend has a Verizon iPhone 6 - I see -108 dbm on this friend's phone, 7mbps down, 1mbps up. I test with T-Mobile similar signal but 25mbps down and 5.8 mbps up..

    Do Verizon iPhones have issues picking up LTE?

    Anyone here have 5 bars on LTE with Verizon -- if so, how often?

    It would be interesting to know for folks with iPhone 6 and 6s' in particular if you bring up the dbm meter in the top left corner:

    Then note what type of signal you see and where is your phone when you test it?

    For me:
    T-Mobile: average: -102 to -107 (main floor/basement) LTE (speeds generally 20-30mbps down, 5-10 mbps up almost all of the time)
    Verizon: -102 LTE to -114 (main floor/basement) (8-12 mbps down, 1-2 mbps up when peak)
    ATT: -102 to -108 (main floor/basement) LTE (2mbps down, 1mbps up when peak)


    When driving I see AT&T and T-Mobile consistent 4-5 bars (and -68dbm or lower (in the -60s))! For Verizon I only once saw 5 bars when I was about 30ft from a tower. Really? When driving I'd normally see between 1-3 bars of LTE and it was always changing between those 1-3 bars. Where as with ATT or T-Mobile the LTE generally stays at 3-4 bars of LTE driving the same route.

    Im currently searching forums to see if this very thing is happening. I had a Verizon 5s back around October. I went and the whole family got 6s's. I have a 6s Plus and immediately I noticed the signal isn't as strong as it was on my 5s in similar places. Very rarely do I see 5 bars on this 6s in places I did before. I use a Wilson Antenna cradle as well. So I almost always had 5 bars on my 5s, and now the 6s Its usually 3 bars. Sometimes 4. Also, Ive noticed something strange with the 6s+....when I'm getting 2 bars in an area where I know I should be getting 4-5...IE city. I can turn on airplane mode and then turn off AP mode and cause it to search for signal and boom, 5 bars.
    Originally I was attributing this to false bar correlation to db. What I mean was, as I understand it, the bars are just a picture painted for us based on a range of db.
    Meaning they say for example "anything between range of -100db thru -90db we call 4 bars, anything -89db thru -70db we call 5 bars"
    These are not accurate numbers I'm using, I'm just saying for example.
    But I figured on the 5s it was just a matter of Apple calling 5bars at -100db where as the 6s phones Apple decided -100db was now 3 bars. So basically if you have -100db its same signal, just not painted as such with bar representation.
    I noticed on both phones there were times when I could out the phone in the cradle and it actually dropped bars. Made no sense, but some of those times the db actually improved while showing less bars.
    Before I turn on cradle Id have say -110db signal and showing 3 bars.
    Id then turn on the cradle and it would drop to 2 bars but signal would increase to -89db.
    Confused the **** out of me. I don't get it.
