Although, Apple has previously denied the #Bendgate issue of the iPhone 6 and iPhone 6 Plus, and called it an "extremely rare" case under normal usage, the company has apparently made some changes to the build quality of the upcoming iPhone 6s and iPhone 6s Plus to avoid any #Bendgate controversy.
According to Unbox Therapy, Apple has reinforce its upcoming iPhone 6s by making the areas around the home and volume buttons slightly thicker measuring at 1.9mm compared to the iPhone 6's 1.14mm, while delivering a slightly thin rear shell weighing at 25g compared to last-gen's 27g, which suggest that Apple will be using the rumored 7000 Series anodized aluminum for its next-gen iPhones.
