Finally there is a study on iPhone dropped calls and different networks. When AT&T was the only provider of the iPhone majority of the people blamed the phone for dropped calls but now with Verizon in the mix we can analyze how the phone does on a different network. According to a recent study from ChangeWave Research, Verizon iPhone users experienced a dropped call only 1.8% of the time whereas, AT&T iphone users experienced a dropped call 4.8% of the time over a 90 month period. Some people might argue that the CDMA and GSM networks are what is making the difference. Maybe the iPhone 4’s CDMA network structure is better than the GSM? Also another intersting point to note from the research was that AT&T overall as a company has twice as many dropped calls as any other network.

What are your thoughts on this research or the results from the research?

  1. It is location. There is a spot on my commute that maintains 5 bars, but that exact spot drops my call 100% of the time. I rarely ever drop calls anywhere else So if I ran a test, and drove by that spot, my calls would drop 100% of the time. And then I can publish that in big headlines. Also, did you see the Consumer Reports this month? They can’t reccomend the Verizon iPhone because it “drops calls when your thumb covers the antenna just like the AT&T iPhone”. But you know what? No one in the media has reported this…

  2. are not both devices designed differently? if i remember correctly they actually tackled the reception issue when redesigning a few of the internal components… i think i will have to search through my emails to find the video.

  3. […] Schneider: 2011-Apr-05 I still say location is everything. In Utah I hardly (if ever) […]

  4. so wait…are we saying it is still dropping calls or it is still dropping calls?

  5. The fact that on both Verizon and AT&T the iPhone 4 has higher dropped call rates than the network as a whole is a little bit telling…

  6. AT&T is also the largest network in the nation, so of course they are going to have more dropped calls than any other. The study for AT&T mentioned 90 months. Verizon hasnt had the iphone for 90 months yet and still does not have the iphone user base that AT&T has, so its not accurate. And as far as the Iphone… its the device. i used to works as an ATT CSR, one thing on the device that wasnt really improved since the Iphone 3G is the antenna they said they did, but that was just a change in the casing. so of course when you are in bogged areas it gets worse. We got in more calls about the iphone than all the others combined. Overall its a good phone that can do just about anything you want it to, except make calls.

  7. @l3v5y: sounds to me like apple doenst know the first thing about making phones. Just sell the shit as an iPod with a cellular connection and we wouldn’t have this problem. But noooo….steve wants to call it iPhone….too bad he has no understanding of how a “phone” is supposed to behave. Shame.

  8. I have AT&T and i have a WP7 device – the LG Quantum, I got it when it came out and I have not had a SINGLE dropped call. plus it looks better! WP7 is where its at! OS doesn’t lag like android and actually works unlike the Iphone.

  9. @James Schneider: I would agree. I’ve had a Razor, a Ming, a Fuze, and now a Captivate on CIngular/AT&T and the only time i drop calls is on the rural part of the highway behind some mountains…

  10. I have had major dropped calls with the Verizon iPhone- 30% marginal areas. I am on my 4th phone. I started to complain within days of getting it back in Feb. After many, many discussions with various techs at Verizon it seems that, according to a senior, local Verizon engineer living in the area where I experience problems that it is a weaker signal areas but where other G3 phones have no issues. A “2-bar” area.

    Initially, Verizon claimed many reasons for the problem but all proved to be wrong.

    What is unique is that the initial call is fine for the first 5 to 10 minutes the other party complains of breaking up and in most cases the call will drop or become too garbled to continue. Immediately after the drop the reconnection will only work for a minute or less and then drops again. Never do I hear any break up at my end. If the initial call is short then usually there is no problem. Like it degrades as the phone physically warms up.

    Yesterday a local Verizon engineer called me and we reviewed the issues and while speaking with him the call deteriorated and the dropped after about 10 mins. The following 3 calls he made back to me also dropped within a minute. He had to call me on a land line to finish the conversation.

    But here’s the interesting news.He told me that Apple, Qualcomm and Version are aware if this issue and that happens in slightly marginal signal areas and that all 3 companies are working to solve the problem. He claims it’s the Apple software that controls the Qualcomm CDMA chipset and that he expects it to be fixed by Apple in a few months. In the meantime he suggested that I go back to my old Razr G3 until then.

    I am checking with Apple and Qualcomm to verify. anyone else heard of this issue?

  11. No, but you might want to check out the HTC Trophy that hopefully will be released by Verizon this (or next) Thursday. For all your troubles, Verizon should give you this new Windows Phone. Keep your Razr in the drawer.
