Inside the iPhone 6 Plus are an array of chips from a number of vendors including Qualcomm, Broadcom, NXP, Texas Instruments, and Avago. And taking pride of place in the middle of all that is Apple's own A8 processor, and that's teamed with 1GB of Elpida LPDDR3 RAM.
Here is a listing of the chips that have so far been identified:
Apple A8 APL1011 SoC + Elpida 1 GB LPDDR3 RAM (as denoted by the markings EDF8164A3PM-GD-F)
NXP LPC18B1UK ARM Cortex-M3 Microcontrollers (which is the proper name for the M8 motion coprocessor)
Qualcomm MDM9625M LTE Modem
Skyworks 77802-23 Low Band LTE PAD
Avago A8020 High Band PAD
Avago A8010 Ultra High Band PA + FBARs
TriQuint TQF6410 3G EDGE power amplifier module
InvenSense MP67B 6-axis gyroscope and accelerometer combo
According to Sterne Agee analysts Vijay Rakesh and Troy Cowdrey the biggest winders are Avago, SkyWorks and NXP, who have seen component content for the iPhone 6 increase by 30 to 90 percent compared to the iPhone 5S. Qualcomm also gains more carrier aggregation, and the NAND boost to 128GB is also good for memory suppliers Micron and Sandisk.
The battery is a monster 43 gram unit and is rated at 3.82 V and 11.1 Wh of energy, for a total of 2915 mAh, which is nearly double the capacity of the battery found inside the iPhone 5S, and slightly bigger than the battery inside the Galaxy S5. The new battery gives the iPhone 6 Plus up to 24 hours on 3G, and 384 hours of standby time, which is a huge increase over both the iPhone 5S and the iPhone 6.
There are also many more internal improvements that apple has made to the iPhone 6 Plus. The new iSight camera features phase-detection autofocus – common on DSLRs but relatively new to smartphones – and optical stabilization.
However, when it comes to the protruding "camera nubbin," even iFixit are worried about the impact and impact might have on it (pun fully intended).
"The lens cover may be made out of sapphire glass, but we're still concerned about what this design choice might mean for durability," iFixit writes in their teardown piece.
Also new is the vibrator assembly that replaces the old style "motor with an off-set weight" with an electromagnet that vibrates a weight. It's a pretty cool and novel approach to vibrations. I suspect the new design is not only more robust, but allows for a greater range of vibrations.
The power and volume buttons on the new iPhone now feature a rubber gasket that should help with keeping dirt, dust and moisture from making its way inside the handset.
iFixit awarded the iPhone 6 Plus a repairability score of 7 out of 10 (where 10 is the easiest to repair). Praised was the ease of access and how simple screen and battery replacements, and the fact that the fingerprint sensor cable has been rerouted and lengthened (the previous design made tearing the cable easy when opening the handset). However, they criticized the use of proprietary Pentalobe screws and the fact that Apple doesn't share repair information with third-parties.
