Apple CEO Tim Cook refused to discuss the iPhone 6 during an appearance in Beijing on Jan. 18, but did promise "great things" are coming in 2014.
"We never talk about future things," Cook said. "We have great things we are working on but we want to keep them secret. That way you will be so much happier when you see it."
One of the things Cook could be referring to is that the next device might include liquidmetal alloy.
A report by MacRumors indicated that Apple might try implementing liquidmetal alloy into its next smartphone.
Apple has never released an iPhone with liquidmetal alloy, despite making a deal with Liquidmetal Technologies in 2010.
"One of these patent applications proposes using Liquidmetal alloys in pressure sensors such as those found in buttons and switches on mobile devices, offering greater durability under repeated use," MacRumors said in its report. "Figures accompanying the patent application closely resemble the iconic home button found on Apple's iOS devices."
Earlier this week rumors had circulated saying the next iPhone, which is assumed to be the iPhone 6, will be released in May 2014.
Jefferies analyst Peter Misek seems confident the phone won't launch until June 2014 however, according to FinancialPost.com.
The analyst said the phone's improved display and possible fingerprint sensors would delay the phone's release.
Apple will supposedly launch two iPhone devices this year with screens measuring 4.7 and 5.7-inches, according to Chinese social media website Weibo.
Cook was at China Mobile's headquarters store for the iPhone launch in China, according to Reuters.
After reaching a deal with China Mobile, the company could potentially add 763 million more subscribers.
