iPhone 5S: 1 in 3 will upgrade to new model
A third of existing UK iPhone users say they want the new Apple iPhone 5S, indicating a drop in enthusiasm for the Apple phone brand since last year.
In a poll of 1,000 UK adults conducted by online survey company Usurv immediately after the iPhone launch event last night, 31 per cent of existing iPhone users said they wanted the new Apple iPhone 5S.

This compares to 44 per cent of UK iPhone users who were willing to upgrade to the iPhone 5 directly after its launch last year.
The new iPhone 5S
Of all the smartphone users surveyed, (including those who do not currently have an iPhone), 11 per cent said they wanted to upgrade to the new iPhone 5S without needing any further information about the product. Last year’s survey found 20 per cent were ready to switch to the iPhone 5 model immediately after launch.
Users of the iPhone’s main competitor, the Samsung Galaxy, are mostly staying loyal, with only 6 per cent saying they want to switch to the iPhone 5S. However, 13 per cent of Blackberry users are ready to switch to the iPhone 5S – more than for any other competing brand.
"While 31 per cent of iPhone users wanting to have the new iPhone 5S can hardly be called a failure, the desire for the phone does seem muted, with fewer people immediately excited by the device than for last year’s model," said Guy Potter, director and market researcher at Usurv.
"Of the new features, only the fingerprint reader seems to have caught people’s attention. The brand is under pressure to deliver excitement and innovation at every launch and this time the initial mood indicates that in that sense it has failed."
The research found that Apple may be on track with the other new phone announced yesterday – the less pricey iPhone 5C ‘budget’ model available for £469, SIM-free.
Usurv found that high prices for previous Apple devices have been an obstacle for many UK phone-buyers, with 42 per cent revealing they had wanted an iPhone in the past but were put off because it was too expensive.
