3D Touch display, not 7000 series aluminum causes iPhone 6s/6s Plus weight gain
In a sea of surprisingly meaningful improvements for iterative upgrades, anticipated by tipsters and largely confirmed on the heels of the iPhone 6s and 6s Plus announcements, it was perhaps most shocking to hear a downgrade was also in the cards.
Unlike battery capacity, Apple took a transparent, candid approach to heft inflations, releasing official dimensions and weight numbers off the bat. As rumored, the iPhone 6s and 6s Plus are ever so slightly thicker than their predecessors, at 7.1 and 7.3 mm respectively compared to 6.9 and 7.1, and they’re marginally heavier too.
Tipping the scales at 143 and 192 grams, the two new 3D Touch-enabled iDevices should feel a little bulkier in the hand of iPhone 6 or 6 Plus owners, given the “OGs” weigh 129 and 172 grams. But of course, Cupertino made this build compromise for all the right reasons, even if batteries didn’t increase in size, and the ultra-robust 7000 series aluminum frames were actually just as slender as last year’s bendy skeletons.
The justification for the weight gain is thus as simple as it is predictable, with 3D Touch, aka Force Touch display assemblies requiring an extra new pressure-measuring layer, as well as a capacitive pressure sensor built into the backlight.
The grand total of the more simplistic iPhone 6 and 6 Plus display assembly load was reportedly 12 and 19 grams, while the advanced gesture-facilitating components of the 6s and 6s Plus scale at 29 and 40 grams. The resulting 17 and 21 grams differences are actually larger than the overall gaps in the constructions of the two iPhone generations, so at the end of the day, Apple seemingly pulled off yet another impressive engineering feat.
