ChangeWave survey more than 4000 consumers to learn their view of various aspects of iPhone 4 use on AT&T’s and Verizon’s networks. Assuming the results provide a reasonably accurate reflection of the general population of iPhone 4 users, the results are fascinating.
As expected, Verizon iPhone 4 customers reported dropped calls less than AT&T iPhone customers (1.8% to 4.8%). However, what is even more interesting is ChangeWave’s historical chart of dropped call responses for 90 day periods going back to September 2008. These figures do not involve the iPhone 4 which did not exist at that point but provide an interesting overall perspective of dropped calls by each company. Verizon started with a relatively low reported rate (2.7%) and has steadily improved to 1.4% (note that the iPhone 4 reported rate is 1.8%). AT&T, on the other hand, has become steadily worse over time. They started with 3.6% dropped calls peaked at a horrendous 6% in September 2010 and improved to 4.6% in the last report. However, it is still worse than the 3.6% rate they started with in September 2008. You can see this clearly in ChangeWave’s Percentage of Overall Dropped Calls chart reproduced here.
Surprisingly, dropped calls do not appear to significantly influence iPhone 4 users’ overal satisfication levels. ChangeWave notes: In terms of overall satisfaction the two iPhones are virtually indistinguishable.
