Introdução
Apple's gone and skipped its iPhone “S" update, so we followed suit and skipped ahead a couple timezones. We're here at Circuitwise headquarters in Sydney, Australia, bringing you the iPhone 8 teardown (and the 8 Plus too!) as early as you can get it. Time to find out if Apple's playing a game of mere numerical catch-up to Samsung’s Galaxy S8 line, or if glass backing and wireless charging warrants skipping ahead a grade. Let’s crack the front and back open it up to see!

The 8 has some slick new tech, but is it enough to warrant the upgraded digit? You be the judge:
-
A11 Bionic chip with embedded M11 motion coprocessor
-
64 or 256 GB onboard storage capacity
-
4.7-inch IPS multitouch Retina HD display with 1334 × 750 resolution (326 ppi)
-
12 MP camera with ƒ/1.8 aperture, optical image stabilization, and 5x digital zoom
-
7 MP FaceTime HD camera with ƒ/2.2 aperture and 1080p HD recording capability
-
Support for fast-charge and Qi wireless charging
-
802.11a/b/g/n/ac Wi‑Fi w/MIMO + Bluetooth 5.0 + NFC
-
-
-
As we start our teardownunder we're greeted by a now-familiar face. Features include:
-
Solid-state home "button" with Touch ID fingerprint sensor.
-
A (still) IPS display similar to the one we found in the iPhone 7 (but now featuring True Tone).
-
On the backside, we spy the iPhone's snazzy new glass backing with its seven-layer color finish.
-
Apple assures everyone that this rear panel is reinforced with "an internal laser-welded steel and copper structure," but time and durability tests will tell if this phone will suffer from a snap, crackle, pop—or yet another Bendgate.
-
Finally, before getting to work, we take a second to line up our new gold iPhone 8 and yesteryear's rose gold 6s. Apple has certainly refined (and re-refined) this design, in addition to stripping a little pink from the finish.
Square Trade break testing didn’t show very good results. The verdict: iPhone 8 and iPhone 8 Plus are definitely not very durable (although both phones beat the Note 8).
And I understand the back is not covered under insurance as well.
“Square Trade gave the iPhone 8 a breakability score of 67, the iPhone 8 Plus a breakability score of 74, and the Galaxy Note 8 a breakability score of 80. At 67 and 74, iPhone 8 and 8 Plus are at "medium risk" of breakage from a drop, while the Galaxy Note 8 is at "high risk." The Galaxy Note 8 fared worse because it was non-functional after some of the tests, while the iPhone 8 and 8 Plus remained usable despite the broken glass. “

-
Before we excavate, we X-ray!
-
Our pals at Creative Electron came down under to Circuitwise and snagged some stellar sneak peek imagery.
-
The seamless back gives way to some intricate insides. The first thing we spy is the brand new wireless charging coil!
-
More on that later. For now, we put down the X-ray goggles to plan our attack.
-
Turns out you don't need X-ray vision to see the model number on this blank-backed phone—it's here on the rosy gold box—A1863!
-
It seems that when Apple set out to clean up the back of the iPhone, it decided to follow all the way through. We're guessing we won't find a cute ID card in the SIM tray, though.

Ferramenta utilizada neste passo:iOpener$12.99
-
Time to get this teardown underway. After twirling away the pentalobe screws, we need some heat as an antidote to the waterproof display seals.
-
iOpener—bam! Seals softened. Next we pull the iSclack out of our tool bag for some pulling power, and slice through the adhesive with a little help from
our friendsopening picks. -
... and we're in! A first glance reveals nothing new—yet. But we've only just scratched the glassy surface.
at this point, fingers crossed that the iPhone 7 display will also work, just like the S and SE are compatible!!
-
-
Ferramenta utilizada neste passo:Phillips #000 Screwdriver$5.49
-
As we crack open this
bookdisplay, we are greeted by the familiar display cable bracket. But instead of the cursed tri-point screws, we're happy to report that we're met with friendly Phillips #000 screws! -
We quickly decouple a few cables—the battery, display, and home button cables to be exact—and the display is free!
-
We note a lack of gaskets on the display's pentalobe tabs, which was previously seen in the iPhone 7.
Is the iPhone 8 LCD assembly the same as an iPhone 7? Are the parts cross-compatible for repairs?
Gaskets (aka “boots” in apple-speak) on the pentalobe tabs (aka “fangs” in apple-speak) were never meant to provide water resistance. They were on the & for another purpose
It has no water resistance. Mine half submerged in a creek for 30 seconds while inside a LifeProof waterproof case. The phone was ruined. Claim and rating is false. Also phone warped in a year and a half while living inside that case.
waterproof and water resistance are two totally different terms. Waterproof is when a phone can be submerged in water, water resistance is when it can be rained on for short periods of time and still function properly. After any repair is done any and all waterproof/resistance is then gone.
-
-
-
We make a grab for the battery's stretch-release adhesive strips, and find there are two more of these guys than we're used to.
-
But that's okay—we just ask for a hand (or two), and remove all four at once!
-
We easily throw back the
mozzarella stickspull tabs as the battery springs free effortlessly.
You need to remove the vibe (“taptic engine”) and any other nearby, sharp components before pulling the adhesive tabs.

-
Now that this juicy battery pack is out, we can see how it compares to its competitors!
-
Fully topped off, this 3.82 V, 1821 mAh cell will deliver up to 6.96 Wh of power.
-
Before you get hopping mad about battery news: despite the drop in capacity, Apple claims battery life will be comparable to last year’s unit.
Are the physical dimensions of this battery the same as the iPhone 7 battery? It would be interesting if you could swap this one for the high capacity iPhone 7 battery.
fyi the battery’s are expanding in the cases :P

Ferramenta utilizada neste passo:Precision Tweezers Set$9.95
-
We pluck the main camera in pursuit of the logic board.
-
The iPhone 8 has the same ƒ/1.8, 6-element lens that we saw on the iPhone 7, but everything else about the camera is new and improved.
-
The 8's sensor is bigger than the 7's, but specs the same 12 MP resolution. This means the individual pixels are larger—letting in more light, improving colors, and decreasing noise.
-
But wait, there's more! Improved image processing software shows Apple still has a few clever tricks up its sleeve.
-
We've seen this before, but not with the naked eye! Neat X-rays reveal magnets in the four corners of the camera—giving this camera some advanced vision of its own through OIS.
Yes! The sensor size please!
is the camera lens made by sony?
Vous avez zappé le démontage de la carte mère côté gauche en haut !!!!

-
Ferramenta utilizada neste passo:Mako Driver Kit - 64 Precision Bits$39.95
-
As our quest continues, we find some quirky cables and brackets!
-
First out: a new Lightning port bracket that seems to reinforce the new peach-colored port and trap the Taptic engine.
-
Up to now, we've gleefully plugged along with our Phillips screwdriver—but alas, all good things must come to an end. In removing this bracket, we encountered our first tri-point screw. Still, it's no match for our 64 Bit Driver Kit!
-
Next: a strange interconnect/antenna cable over the speaker.
-
Finally: the Taptic Engine nestled in a series of tiny fiddly connectors.
Fairly obviously you would have to use the 64 Bit Driver kit, as the new iOS is no longer 32 Bit compatible. :-)
-
-
-
The final barrier to logic board gold: this tiny hidden screw, which we find trapped under the waterproof silicone seals!
-
We get another helping hand in the form of Jumpy's for logic board removal!
It would not to be waterproof silicone seals! Seems like to be a stable cushion(sponge/poron) for board to board connector.
-
-
-
Drumroll please—it's chip time! Special thanks to the folks at TechInsights for helping scope out this silicon:
-
Apple 339S00434 A11 Bionic SoC layered over SK Hynix H9HKNNNBRMMUUR 2 GB LPDDR4x RAM

-
Skyworks SKY77366-17 quad-band GSM power amplifier module
-
NXP Semiconductor 80V18 (PN80V) secure NFC module
SK Hynix H9HKNNNBRMMUUR should be LPDDR4x.
Refer to the link https://www.skhynix.com/eng/support/tech...
There is one documentation related to chip marking about LPDDR4. From the marking information, H9HKNNNBRMMUUR should be LPDDR4x.

-
Logic board dispatched, we get down to
brass tacksplastic bits. Today's bits feature the speaker and barometric vent. -
Another small spec bump: Apple touts that the speakers are 25% louder in the iPhone 8—although there is some debate as to whether it is noticeable.
-
The same dozen
donutspeaker holes line the bottom of this iPhone as the 7. -
We also find familiar signs of waterproofing in the form of seals and little rubber gaskets.
-
-
-
The rear case is looking a little thin on components, but we still find a few pieces that invite inquiry.
-
The peach-colored Lightning connector looks like it has changed a li'l since the iPhone 7. Without getting distracted by the desert camo, we notice a new form factor. Better ingress protection, mayhaps?
-
We dig through some black tape that covers some copper tape that covers some
black tape... wait a second ... -
That ain't just black tape, it's the elusive Apple-branded, Qi (pronounced "chee")-enabled wireless charging coil!
From the Qi Certified List found at: https://www.wirelesspowerconsortium.com/...
iPhone 8 (A1863) Basic Power Profile (5 Watt), Version 1.2.3; max received power 5 W
The Samsung Note 8 has the same BPP (5watt), Version 1.2.3, but max power received is 4.5 W
The LG V30 has an Extended Power Profile (15 Watt), Version 1.2.3, max power received 10.5 W
HELP! I need a replacement for that tiny little cable on the charging port assembly, that’s just to the right of the port itself. I sneezed while replacing the %#*@ port & it is GONE.
I recently replaced my screen and battery. When taking out the battery I accidentally tore into the black cover on the Qi charging pad. It revealed a silver material inside.
Not knowing what to do, I covered it up with tape. However, when trying to boot, I got stuck in the boot loop. I am able to go into DFU mode, but I can’t restore the phone in iTunes. I believe the boot loop is due to a hardware issue.
Could it be from the Qi charging pad mishap? If so, could I simply disconnect the Qi charging pad harness from the board? I don’t use it, anyway.
Hi Steven, probably damaging the qi has now created a short circuit and disconnecting it you should solve

Ferramenta utilizada neste passo:Curved Razor Blade$9.99
-
We take a stab at separating the rear glass, but after a lot of heat and wetwork, we've instead shivved our way under the reinforcement panel.
-
After more arduous stabbing, we finally get the seven-layer
burritoglass sandwich off of the midframe. -
The process left the backing plate a bit bent out of shape—we have no idea how Apple plans to do this, but they seem to be keeping the secret squirreled away...
-
And no, we didn't let snails figure-skate on the back—that's glue. Lots of it.
Why don’t you guys start selling heat tables too so you can tell us at what temperature the adhesive starts to melt?
Could you use an LCD separator machine to remove the rear glass? The ones with heated surface with suction and wire - seems like an easier option than the razor blade.
-
-
-
We finally turn back to the well-known display and pluck the final features away.
-
Goodbye home button.
-
Goodbye front-facing sensor cable.
-
Goodbye LCD shield.
-
Oh, but hey li'l chip we can't identify.
Maybe the unidentified chip has something to do with Apple’s calibration machine and their attempt to prevent installation of aftermarket screens?? Just a wild conspiracy guess…
Maybe this had been answered on another thread but can someone tell me what the chip on the screen flex cable is for?
The LCD driver chip is most likely to be Synaptics R63318 device and it has been continuously used in iPhone6~8, except iPhone X

That's all she wrote! Well, at least for now—we've got a few more words and photos in store for you in the next few days!
-
Thanks heaps to Circuitwise for hosting us at their sweet facility in Sydney. (Seriously, check out that sweeet soldering video.)
-
And big thanks to the Creative Electron team for providing some serious X-ray support!
-
- The two most commonly replaced components, display and battery, remain straightforward to access with the proper knowledge and tools.
- The addition of wireless charging means less strain on your Lightning port, a common point of failure.
- Water and dust seals complicate repair, but make the need for difficult liquid damage repairs less likely.
- The battery connector once again sports common Phillips/JIS fasteners—but you’ll still need up to four different driver types for many repairs.
- The durability of the glass back remains to be seen—but replacements are likely to be very difficult.
- The iPhone’s lower components, once readily removed, now lie trapped under a fussy combination of brackets and delicately folded flex cables.

Link anyone?
It looks like it's the same screen as the iPhone 7, something like the iPhone 5S and SE, maybe?
Hopefully, although since the new one supports true tone, it may not. However, those sensors may not be integrated into the display and just be a part of the camera and speakerphone assembly.
Edit: also, the black stuff isn't present on any iPhone 7 displays Ive got, also, the top clip on the left side seems to be rounded off, while on my 7 displays, they have a little sharpish point coming out of each side.
Andrew -
Also, on the 8 display, there is a little bit of text on a black bit of plastic which reads “F08+C”, on my 8 display, it reads “F06+A”
Edit: also there are metal clips at the top of the 8 display, on the 7 they're made from plastic
Andrew -
No video stream?
Cool idea on the “Live Teardown”… as always great photography and good explanations.
Far as step 5 (Screen removal). The flex cables look very similar to the iphone 7. From reading the comments above the tech mentions some frame differences. Have you by chance plugged the screen assembly into an iphone 7 to see if the LCD+Digi/3D touch/home button work, and maybe front camera assembly work as well?
ooH! Do you think Apple would allow parts switching. I would saay ‘No Way’!!
JOhn -
Now are 4 Adhesive Strips, at the top and bottom of the battery? The Adhesive Strips, do not stand above the wireless charger, right?
Yup! That’s correct.
Nope. Been around since the 5S/5C days.
No this has been in iPhones and iPads for a while to remove the battery. what is new is that their are 4 tabs, previously I believe there were just 2.
Awesome tear down. Thank you.
I see the Qualcomm chip. Is this the A1863 iPhone 8?
Glad you’re enjoying it, we’re almost done! You’re correct, this is an A1863 iPhone 8.
So wirelless charging is with a flex cable ? , i’m curious about the back glass cover if its removable (easy to) because i’m thinking ill be changing lots of those…
Edit : Seems like they don't want us to change those… how come the aluminum is so deformed? no usage of heat or glue remover used?
mum mum mum mum
Awesome teardown. Does iPhone 8 have USB 3.0 Controller?
Do you plan to follow with iPhone 8 plus? Thanks for sharing this! Made my day
Does IPhone 8 support quick charge by USB Type-C and PD
All three phones released support USB-C quick charging with a Lighting to USB-C cable and a USB-C charging brick (for MacBook/MacBook Pro w/ TB3).
Apple 338S00248, 338S00309, and S3830028
Are any of these the Dialog Power Management IC? Similar serial numbers to Dialog’s chip in the 7 (Dialog 338S00225 Power Management IC)
TechInsights updated their (8 plus teardown) info to show 338S00309 and 338S00306 as Apple/Dialog and commented that there is one more PMIC from Dialog compared to the 7. The 338S00306 chip isn’t even mentioned in this article. It looks like the chip has tape (or some other covering) over the top of it in the photo on this article so the markings can’t be identified. It would be the chip just below the NXP80V18 secure NFC module. Also, I think one of the orange circled PMIC chips in this article is actually a 338S00295 Audio Amp instead.
Vash Kae -
Any details on the earpiece speaker/Mic as compared to i7
Please what can you say about GNSS chipset (annouced by Apple)? Embedded in MDM9655? Thanks
Yes. The iPhone model with Qualcomm modem inside, the GNSS is supported by Qualcomm modem. If it is intel modem inside, there should be a GNSS chip from other other vendor(supposedly, it will be Broadcom.)
JJ Wu -
Does iphone8 has or change in Digital to Analog (DAC) part ? Something like AKM , Wolfsen ,Cirrus logic etc.
I don’t think the P215 730N71T is an ET IC . There is no DC-DC inductor and capacitor around. And it is very unreasonable to place the PAPM so closed to PAs
Great teardown. I have been looking forward to this all week! The back glass design reminds me of the iPhone 4 back glass assembly, with the layer of glass being excessively glued to a thin metal plate that was built in to a plastic frame who’s design varied depending on GSM or CDMA model. However, other than adding Qi charging, the difference between the iPhone 4 and iPhone 8 back glass is the location of the thin metal plate. For the iPhone 4, it was attached to the removable back glass assembly. With the iPhone 8, the thin metal plate is built into the phone’s frame assembly. From what I have been reading, Apple store employees claim that a broken glass on the new iPhone 8 series counts as a whole device replacement under AppleCare and therefore subject to a larger fee. I am curious to know if Apple designed these new models to have the entire frame replaced rather than just the back glass to prevent repair shops from providing inevitable back glass repairs.
Is the iPhone 8 LCD assembly the same as an iPhone 7? Are the parts cross-compatible for repairs?
Looking forward to your bend test! There appears to be several fake ones on YouTube in which reviewers are using either a six or seven and claiming it to be an 8. One that looks fairly real claims that the 8 is much better than the 7 (perhaps all those layers of glass help). I would like to know if the 8 passes the skinny gene tests.
Gee iLuddite, what ever happened to the good old days of electronics when they had huge cabinets and everything could be fixed with a bang of your hand on it? I am constantly sickened by your constant complaining that Apple products that rarely if ever, need repairs are difficult for YOU to repair. Somehow, you expect anyone with no knowledge or experience to be able to also repair ANY electronics on their own.

anyone know which Bosch Sensortec product in particular?

it doesn’t specify on the website & they haven’t got back to my emailed enquiry
Lightning connector runs at USB3 speeds yet ?!?!?! apple are such douches when to comes to USB speed increases
Dude the 7 series ran at USB 3 speeds.
Andrew -
Really?! Using the regular lightning cable it came with? I though all those are USB2!
The iPhone 7 runs at USB 3 speeds? Thats funny because my 2017 Kaby Lake i7 Macbook pro USB-C to lightning cable, and all my other lightning cables, have never transferred to my iPhone 7+ faster than USB 2.0 speeds. 100GB/14,000 songs takes like an hour to transfer?
Tom M -
Data transfer speeds via Lightning adapter is becoming less and less important—the last iTunes update removed iOS apps from iTunes. Apple is pushing more and more data transfers over wireless.
Yoron -
Would like to see the Camera Sensor size compared against the iPhone 7’s.
Yes please! iFixit help us out and show a comparison of the 7 and 8 main camera sensors? The 8 is supposed to have a bigger sensor.
Mike R -
Saludos y muchas gracias a esta gran comunidad que día a día se prepara mediante la investigación, observación y experimentación, así se logra la mejora continua y se actualiza el conocimiento y la técnica, muy bien por ello, buenas tardes.
Rumor has it there are two generations of the Wireless Charging Coil out on the street. Samsung flagships opting for the faster one and iPhone 8 opting for the slower one. Any truth to that? What are the specs of each? Having trouble finding them in google-land.
Samsung boasts “Fast charging “, and Apple boasts “Wireless charging “
That sort of settled it for me.
unklbyl -
Both the iPhone 8 and Samsung’s latest (Note 8) utilize Qi’s Basic Power Profile (5 Watt), with the iPhone capable of receiving 5W, and the Note receiving 4.5W. The LG V30 utilizes the Extended Power Profile (15W) capable of receiving 10.5W. This pulled from the Wireless Power Consortium’s certified devices list (the LG V30 page: https://www.wirelesspowerconsortium.com/...) (the iPhone 8 page: https://www.wirelesspowerconsortium.com/...)
The iPhone 8 also supports fast charging—via Apple’s USB-C to Lightning cable (must be USB-C PD) and a compatible wall wart (like Apple’s 29W USB-C wall adapter).
Yoron -
Sorry I can’t take the TRUE TONE comparison until you do a side by side comparison using same front color iPhone. I believe the black front (over-enhance) enhances true tone and white front deemphasizes it.
thanks a lot for all your help.all your tutos are amazing.thanks a lot
Does iphone 8 allow direct transfer of musicvideo from iphone to computer and computer to iphone without itune software.
the iphone 8 is more like the the iphone 7 just sme few other parts have being introduced but looks so complex i dont know how Apple is trying to solve ##%& that will help save the back glass from getting bent after removed
Does anyone know the screw size next to the lightning port on the bottom of the phone?
If you’re talking about the two exterior screws, they’re the same as in past iPhones—you’ll need a P2 Pentalobe driver to remove them.
I see a very small gap between the frame and screen on my iphone 8 plus,is this normal? Does it compromise with the water resistance in any way?
How do I find a logic bored for a iphone 8 ?
How do I get a logic bored for a iphone 8 I can't seen to find one
hi i need ic touch iphone 8 plus
Does anyone know how many cycles the lightning port is rated for?
Where’s the Microphone?
The microphone is intermittently distant and muffled. I want to check the connections. Any suggestions? I’ll get the tools if I have good troubleshooting steps, thanks!
The primary microphones are at either side of the Lightning port, mounted onto the port’s flex cable. There’s an additional mic on the back, near the camera. First make sure your mic holes are clean—no need to open your phone if they’re just a little clogged up with pocket lint. Good luck!
hi! There’s a cable in step 4… I just broke it. I think it’s the ear speaker. Camera works, speakerphone works, but not the ear speaker (and maybe something else; I haven’t put it all back together again. This process of saving 120 bucks for a new LCD is gonna cost me.
Anyway, can you tell me what it’s called? (its part # is, maybe, b21-01133-03.
it’s that top curvy cable, the only one at the top that connects one side of the phone to the other…
Thank you.
