Gadget Review – iPhone 7 Plus Teardown

iPhone 7 Plus Teardown

Hi I am Gwendolyn with iFixit and today we
are tearing down the brand new iPhone 7 Plus. While the iPhone 7 Plus retains the design
basics of the previous generation it does have a lot of upgrades. Including a new dual camera system, a non
mechanical home button, iP67 water resistance and beefy processor upgrade. But what updates have taken place on the inside
of this new iPhone? Theres only one way to find out and thats
to tear it down.

Getting into the the iPhone 7 Plus was a familiar
affair. Pentablobe screws, Isclack open, although
with a bit more force than weve had to use before, and a little prying. But then a difference. The iPhone 7 Plus opens to the side.

Had we not had some advance warning this could
have been a disaster for our display cables. Good thing we make guides. Another annoying novelty rears its head. We have new screws.

Tripont screws secure both the battery and
display bracket to the iPhone. Fortunately for us, weve come loaded with
our pro tech toolkit and a super handy y00 bit that handles them easily. With screws removed and the cables disconnected
we remove the display. Heading down south the bottom of the phone
we remove a plastic component that According to Apple is a barometric vent.

With the added ingress protection afforded
by the watertight seal, the iPhone uses this baffle to equalize the internal and atmospheric
pressures in order to have an accurate altimeter. Speaking of the Taptic engine its next
to be removed. The taptic engine is a tiny linear actuator
and some zig zag springs that shake a weighted core. The taptic engine precision oscillation is
designed to provide many types of tactile feedback including the sensation of pressing
a mechanical button.

With those two parts removed we have easy
access to the battery adhesive pull tabs that hold the battery in place. This battery is a 3.82V, 2900 mAh, a slight
upgrade over the 2750 mAh of the 6s Plus. Next out were the cameras! Two sensors, two lenses and two sets of optical
image stabilization. One of the camera is a wide angle, just like
the iPhone 6s and the other is a telephoto which allows for optical zoom.

Both of these 12 MP cameras also sport a new
image sensor that Apple claims is 60% faster and 30% more energy efficient than previous
iPhones. After removing some portions of the antenna
assembly, including the antenna flex cable, we get the logic board out. Peeling away the emi shields reveals the chips
on the board, including the new A10 fusion chip and its accompanying 3GB of RAM, and
128GB of Toshiba made NAND Flash storage. IF you want to see the full list of chips
we identified head on over to iFixit.Com, We have a VERY complete list of chips thanks
to some help from our friends at chipworks.

The speaker is next to come out and a closer
inspection reveals some nice spring contacts and ingress protection, meaning this speaker
is helping to keep things out of the phone, namely water. Much has been made about the new models of
iPhone being more water resistant and this is just one instance of that new feature found
on the phone. We also found rubber gaskets and plugs at
the SIM tray port, and some very substantial gasketing at the lightning connector. Speaking of the Lightning cable assembly,
it is moderately glued to the case and it is huge.

Attached to it are those speaker gaskets. These gaskets are a serious water and dust
proofing upgrade from the 6s pluses use of foam adhesive in this location. With the lightning port out we turn our attention
back to the display. By the way, this display is a 5.5-Inch,1920
by1080, Retina HD display with a pixel density of 401 ppi.

But what really interests us is down at the
bottom, the new home button. Its more like the home touch sensor really
and it is removable It won't be a simple procedure, with tiny tri-points and light adhesive on
the cablebut thankfully there is no longer a delicate gasket to replace. Weve come to the end of our teardown and
now we turn our thoughts towards repairability. How did the iPhone 7 Plus score? It got…

A 7 out 10! And heres why… On the upside
The battery is straightforward to access. Removing it requires specialty screwdrivers
and knowledge of the adhesive removal technique, but is not difficult. The solid state home button eliminates a common
point of failure.

Neutral
Improved water and dust protection greatly reduces the need for repairs associated with
environmental damage and accidental spills (but also makes some repairs more difficult). The display assembly continues to be the first
component out, simplifying screen repairs, but the procedure has grown more complicated
with improved waterproofing measures. But on the downside
With the addition of tri-point screws, many iPhone 7 Plus repairs will require up to four
different types of drivers. And thats our Teardown! For the complete teardown including tons of
beautiful high quality images head on over to ifixit.Com.
