Got a shiny new iPhone 6s winging its way to you today? I bet the first thing you do with it won't be to tear it down to see what makes it tick. But this is exactly what the folks at iFixit have done so you don't have to!

So, what's inside the new iPhone 6s? Well, first we have confirmation that the battery is indeed smaller than the one found inside the iPhone 6. The new power pack is 1715 mAh, compared to the 1810 mAh battery found in last year's iPhone 6. Does it matter? In a word, no. Handset life between recharges is, according to Apple, unchanged, so a smaller battery means nothing to the end user.

What's more interesting than discovering a smaller battery is discovering why the battery is smaller to begin with. It seems Apple had to shrink the battery in order to be able to fit the new Taptic feedback engine - which sits below the battery - into the iPhone. Here we see Apple doing what it does best - putting engineering ahead of spec sheet numbers.

The display is also bigger, weighing in at 60 grams, which is 15 grams heavier than the display in the iPhone 6. This extra weight is likely made up of the extra capacitive sensors needed to make the 3D touch feature work.

From a component standpoint, at center stage we have the Apple A9 processor with 2GB of Samsung RAM. Providing connectivity is a Qualcomm MDM9635M LTE Cat 6 modem and a Qualcomm WTR3925 radio frequency transceiver. In fact, looking at the chip list, Qualcomm has come out a big winner.

From the point of view of repairability, the new iPhone 6 s gets a respectable 7 out of 10. The display and battery are both relatively easy to replace once you get beyond the pentalobe screws that Apple uses to keep you out of the device.
