Many iPhone6 Plus users from different areas of the world complaining that their smartphones banned in their pockets.
iPhone6 Plus users had shared the faulty sets pictures on social networking sites including Twitter, Instagram and Facebook.
Several of the Apple’s rivals have also helped publicise the claims.
Apple said that 9 of its flagship brand, iPhone6 Plus users complained about the problem.
In a statement the company noted that the handsets’ shells had been constructed out of “anodised aluminium, which is tempered for extra strength” and also featured stainless steel and titanium parts to reinforce the areas of the phones likely to experience the most stress.
“We chose these high-quality materials and construction very carefully for their strength and durability,” it added.
“We also perform rigorous tests throughout the entire development cycle.
“iPhone 6 and iPhone 6 Plus meet or exceed all of our high quality standards to endure everyday, real life use.
“With normal use a bend in iPhone is extremely rare and through our first six days of sale, a total of nine customers have contacted Apple with a bent iPhone 6 Plus. As with any Apple product, if you have questions please contact Apple.”
Apple’s share price has fallen following the publicity generated by users posting photos of bent iPhones to the internet.
News that it had also pulled an iOS 8 operating system update after iPhone 6 users complained it made their phones unable to make or receive calls had also caused concern.
Apple had previously announced that it had sold more than 10 million units of the iPhone 6 and its larger sibling the iPhone 6 Plus.
“While our team managed the manufacturing ramp better than ever before, we could have sold many more iPhones with greater supply and we are working hard to fill orders as quickly as possible,” its chief executive Tim Cook said in a press release on Monday.
