"Consumers have learned different ways to purchase their Apple products, from ordering online to ordering from retailers and carriers," said Wang. "Apple has also put out information on where consumers can buy their iPhones."

Film industry worker Wang Kelu had ordered three iPhones online and arrived, like many others, on Friday morning to pick them up in person.

"I also came to buy phones for my friends. I wanted other iPhone 6 Pluses, but they didn't have any left so I guess I'll come back again tomorrow."

Apple's Friday launch came hot on the heels of a company product announcement on Thursday in California which revealed new upgrades for the iPad Mini 3, iPad Air 2 and OSX Yosemite, as well as a software update for the Mac operating system.

Wang said that the arrival of the iPhone 6 Plus may hit iPad sales, given the former's screen size is already close in size to a small tablet.

"Right now there are a lot of what we call phablets on the market in China, made by domestic and foreign companies, such as Samsung and LG," said Wang.

"At 5.5 inches, the 6 Plus might turn away consumers from new tablet devices, not just in China but everywhere."

"That said, right now there really isn't a competitor on the market to match the iPhone 6 Plus."

Prices for the iPhone 6 start at 5,288 yuan ($860), and for the iPhone 6 Plus at 6,088 yuan.
