iPhone 5 owners resist the call of the upgrade

An iPhone 5 and 5S.

Despite the addition of a futuristic fingerprint scanner and plenty of under-the-hood improvements, Apple's new iPhone 5S hasn't proven to be much of a draw for people who already own a 5, according to a new report.

Consumer Intelligence Research Partners (PDF) asked 400 buyers of the iPhone 5S and 5C what they were upgrading from. Only 6 percent said the iPhone 5.

For comparison, when the iPhone 5 first came out last year, CIRP asked the same question. At that time, twice the proportion of people, 12 percent, were upgrading from the 4S. 

Despite this, a larger percentage of people buying the 5S and 5C this year were coming from the Apple ecosystem, upgrading from older iPhones. Selling new phones is good, but ideally Apple would like to be converting users of Android or Blackberry, not just keeping the users they already have.

Is this part of a larger trend, or are people just not that smitten with the new iPhones? We'll know more after the next few months of sales bear out any other patterns.
