Apple Inc. may have managed to avoid a repeat of the "Bendgate" controversy that dampened the release of its iPhone 6 Plus by making certain this year's iPhone 6s / Plus models are equipped with a thicker and stronger design and materials.


According to the International Business Times

, "Unbox Therapy" YouTube channel host Lewis Hilsenteger made certain of that by putting the new models through an assortment of rigorous tests that included putting the shell of an iPhone 6 against what appears to be the shell of the unannounced iPhone 6s.

In addition, tests reveal the iPhone 6s case measures at 138.26mm x 67.16mm, compared to 138.09mm x 66.91mm for the iPhone 6. As might be expected, the greatest difference in the level of thickness comes along the sidewall of the volume buttons, the very area where the 2014 models were found to give way and bend.

Actual measurements reveal the iPhone 6s case now measures at 1.9mm, or at nearly twice the thickness level of their predecessor which checked in at 1.14mm.

And yet, the iPhone 6s weighs in at just 25g, or two grams lighter than the iPhone 6 case. At least part of the phenomenon can be attributed to the company's use of a different material for the case, such as the same kind of Series 7000 aluminum used for the Apple Watch.

The iPhones 6s and 6s Plus officially went on sale in stores this weekend and company officials have indicated that early signs point to global sales topping 13 million over the opening weekend.

According to Forbes, thus far both models have also earned critical acclaim based on such subtle changes from last year's model as a new "peek and pop" feature allowing for the easier flow of content specifically playing to rave reviews.

In addition, Re/code recently reported company shares jumped by 2 percent amid reports of brisk pre-order sales.
