The bigger screens but thinner bodies of Apple’s new iPhone 6 and 6 Plus models have come at the cost of rigidity, according to owners who say they bent while being carried in trouser pockets.
A number of users across various forums, sites and Twitter have reported – and pictured – that their phones have become warped after they sat or bent down with them in front and rear trouser pockets. The reports come just after an insurance company claimed that the new iPhones are the most robust ever – though its tests didn’t include bending.
The iPhone 6 and 6 Plus chassis is milled from a solid piece of aluminium alloy whose composition is secret. The weak area of the phone appears to be around the volume buttons, where the frame is at its thinnest and creates a fulcrum point around which the phone bends. Surprisingly, the screen does not break when the phone bends – though it does if the phone is then bent back to a flat profile.
Apple is not the first to have the problem of a large-screened metal-framed smartphone bending under use. Sony’s Xperia Z1, which had a 5in screen and a metal frame, saw users complaining that they bent in pockets, while Samsung Galaxy S4 users had similar complaints, as did BlackBerry Q10 users.
The exact number of iPhone 6 users affected is unknown. The Guardian found dozens of people on Twitter whose iPhone 6 or 6 Plus had bent – though there are also hundreds more echoing news reports and the pictures put up by those who have been affected.
The iPhone 6 Could Bend In Your Pocket… !! haha.. love u APPLE http://ift.tt/XW45ba
— Nelson Cardoz (@nelsoncardoz) September 23, 2014 Testing by Unbox Therapy showed that the iPhone 6 Plus can be bent by applying substantial force by hand.
The amount of force required to bend the smartphone is unlikely to be repeated in all but the skinniest of trousers. Before conducting the test, Lewis Hilsenteger from Unbox Therapy said his 6 Plus showed signs of being bent simply from being in his trouser pocket.
The Guardian’s testing of the phones over the past two weeks has not revealed any tendency towards deformation when normal care is taken.
Previous iPhones, including the iPhone 4, iPhone 5 and iPhone 5S, have suffered from bending, with users complaining about the problem in 2010, 2012 and last year via Apple’s official internet forums.
But the larger and thinner the smartphone, the more likely it is to be damaged by being carried in the pocket under tension.
“In material bending, larger cross-sectional areas [thickness x width] and shorter lengths make things stronger - you can’t easily bend a cube - while the opposite makes things very easy to bend – paper is easily folded,” Jeremy Irons, a design engineer at Creative Engineering explained to Gizmodo. “The increased length and decreased thickness contribute to the weakness of the new iPhone. Strength is proportionally related to length, but strength is affected much more by changes in thickness.”
The thinner and larger the phones get the more susceptible to damage they are likely to be, regardless of how strong the materials used in the phones to reinforce them. Being thin makes large phones more pocketable, but users need to think about the stress and strain in tight pockets as they sit down, regardless of whether they carry them in the back or front pockets.
