No teardown is as highly anticipated as an iPhone teardown—so, to quell your curiosity, our teardown engineers ventured to the land down under and investigated the innards of an iPhone 6s.
iPhone 6s Teardown
iPhone 6s Teardown on September 25, 2015.
Getting into the new iPhone is almost as easy as it was before—thanks to some surprise adhesive lurking beneath the display. Once inside, though, the iPhone 6s quickly distinguished itself from its predecessor. Apple’s new Taptic Engine squished the battery ever-so slightly, the display grew to accommodate additional capacitive sensors, and the A9 got a size bump from last year’s A8. While we can’t confirm the die size—the A9 package itself appears bigger (roughly 14.5 x 15 mm, up from 13.5 x 14.5 mm on the A8). Our guess at the cause of growth? The addition of the embedded M9 motion coprocessor.
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 maintained a robust repairability score of 7/10.
iPhone 6s teardown highlights:
• The rumors are true—the battery capacity is down a bit, and we suspect 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. But 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.
