iFixit: New iPhones have smaller batteries, LPDDR4, are fairly easy to repair

Part of the fun of any new gadget is the painstakingly detailed iFixit teardowns, which often tell us things about the devices we couldn't otherwise find out. The new teardowns of the iPhone 6S and 6S Plus are no exception.

The first point of interest for iPhone watchers is that battery capacity is definitely down a bit, presumably to make space for the new Taptic Engine (the engine measures 35 x 6 x 3.2mm in the 6S and 15 x 8 x 4.9mm in the 6 Plus). Capacity goes from 1810mAh to 1715mAh in the 6S and from 2915mAh to 2750mAh in the 6 Plus. Generally Apple tries to increase the battery size a bit for S-model refreshes, so this is a little disappointing.

Apple's stated battery life for the phones (and the figures from early reviews) indicate that the 6S and 6S Plus get roughly the same amount of battery life as the 6 and 6 Plus, which is attributable to some of the other internal advancements. We know the Apple A9 is built on a new, more power-efficient manufacturing process, even though we don't know who's making it for Apple just yet (leading candidates are TSMC's 16nm process or Samsung's 14nm process). The new Qualcomm MDM9635 LTE modem is made on a 20nm process rather than the previous MDM9625's 28nm process. And the 2GB of RAM is LPDDR4, which should have lower voltage requirements than the previous LPDDR3.
