These lightning cables are complete junk, do not buy them. Even if Apple will in fact replace them for free with no questions asked AND they are really close by, do not do it.
You shouldn't have to have these cables straight at all times, they should be allowed to bend. I don't know of any place anywhere built where the electrical outlets or computer USB ports are at level with the table. You should not have to place your phone on whatever objects you can find just to make it level, that's asinine. There is a major manufacturing problem with these cables and Apple has known about it for quite some time and they refuse to address it.
My girlfriend has the last of our lightning cables now and had kept the cord as humanly straight as possible and it still broke 26 days later. Then there is me, still using the 63 cent cord purchased off Ebay. My boss bought 10 of these things (2 for me, 1 for everyone in our office, and the rest for him). None of ours have broken yet, and we've been using them for almost 6 months.
You can buy these cords in different colors (you can't miss them on ebay) and they are far more resistant to the "accessory not supported" message. As many of you have probably noticed, the breaking/fraying of these lightning cords aren't their only problem, they also frequently get the "accessory not supported" message which causes your phone to stop charging. These messages pop up even when the Lightning Cord is not broken. With every patch Apple implements, these messages get more frequent making it far more difficult to charge your phone. This is also where those 63 cent cables shine, that message is nearly non-existent. You can charge your phone freely and not worry about it, and they are very durable as well.
Another thing to keep in mind; we've now had 4 fires in our district now in the past 7 months that are being traced backed to these Apple Lightning Cords. Electrical engineers have ruled out a problem with the actual electrical socket and their Iphones were not burned (just the cord) Consequently, all these cords had broken/frayed ends on them. These cords from what I've seen are also a fire hazard and should not be used. We've sent out district wide mail notifications warning people on the dangers of these cords.
End result, look on ebay for phone chargers that are meant for Iphone and are not lightning cables. Their are plenty on there for dirt cheap and are far more safe and durable.
