iFixIt tears down the iPhone 6s, 6s Plus

The iPhone 6s and 6s Plus go on sale today and iFixIt has torn 'em down to see what makes 'em tick. iFixIt says that getting into the new iPhones is almost as easy as it was before "thanks to some surprise adhesive lurking beneath the display."

Once inside, though, things are quite different. Apple’s new Taptic Engine compresses the battery slightly, the display is a big bigger in order to accommodate additional capacitive sensors, while the A9 got a size bump (roughly 14.5 x 15 mm, up from 13.5 x 14.5 mm on the A8) from last year’s A8. 

"Our guess at the cause of growth? The addition of the embedded M9 motion coprocessor," says iFixIt. "One thing that didn’t change: repairability. With an easily accessible display, straightforward access to main components, and standard amounts of adhesive, the iPhone 6s [and the 6s Plus] maintained a robust repairability score of 7/10."

Other highlights of the iPhone 6s teardown — which you can find in its entirely here include:

  • The battery capacity is down a bit. The iFixIt gang suspects the reduced battery size is to accommodate the Taptic Engine. The Lithium-ion pack comes in at 3.8 V, 6.55 Whr, and 1715 mAh, a small but notable decrease from the 1810 mAh battery in last year's iPhone 6. However, Apple promises that battery life remains the same.
  • The display assembly gained 15 grams compared to the iPhone 6. The additional capacitive sensors to power their new fancy 3D Touch really beefed up the display.
  • Battery and screen repairs should be fairly straightforward—but unfortunately, the Touch ID cable is paired to the logic board, complicating repairs.

Highlights of the iPhone 6s Plus teardown — which you can find in all its glory here include:

  • The display assembly on the 6s Plus weighs in at 80 g—while on last year's 6 Plus, it weighed a measly 60 g. This astonishing 33% increase in weight is all because of Apple's new 3D Touch technology. That's some heavy stuff.
  •  The battery capacity sits at 2750 mAh; a modest 165 mAh downgrade compared to last year's 6 Plus. Despite the downgrade, Apple claims battery life will be comparable to that of the 6 Plus.
