Nearly half (48 percent) of Brits hope the next iteration of the Apple iPhone will be thinner than previous models, says GoodMobilePhones.co.uk.

Research by the mobile phone comparison site of more than 1,700 Brits revealed longer battery life was the second most-craved feature on the Apple iPhone 5, named by 45 percent of those surveyed. Meanwhile, nearly two in five (39 percent) admitted they want more memory in the next version of Apple's smartphone and just under a third (32 percent) hope the handset will be lighter. The fifth most-hoped for feature was a support for faster internet connections.

Furthermore, 45 percent admitted they will swap their existing smartphone for the Apple iPhone 5 once it has been released. Of these, over a third (38 percent) claim they'll get their hands on the smartphone "as soon as it is released" while 62 percent said they'd wait "a few months".

"It was interesting to see 'thinner handset' top the charts as the thing people most want from the new iPhone 5, and clearly lighter, slimmer technology is important to mobile phone users. I guess we'll all just have to wait and see what we can expect when the phone is released," said Mark Owen, managing director of GoodMobilePhones.co.uk
