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!

Este teardown (desmontagem analítica) não é um guia de reparo. Para reparar seu/sua iPhone 8, use o nosso manual de serviço.

  1. The 8 has some slick new tech, but is it enough to warrant the upgraded digit? You be the judge:
    • 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

  2. As we start our teardownunder we're greeted by a now-familiar face. Features include:
    • 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.

      • Jury is still out on the model number and the missing wheely-bin symbol.

    • 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.

    • Before we excavate, we X-ray!

    • 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!

    • 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 friends opening picks.

    • ... and we're in! A first glance reveals nothing new—yet. But we've only just scratched the glassy surface.

    • As we crack open this book display, 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.

      • However, both the iPhone 7 and iPhone 8 have an IP67 water resistance rating. How are the floodgates still closed!?

    • 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!

      • This procedure requires a wealth of experience, gained in large part due to Stretch Armstrong.

    • We easily throw back the mozzarella sticks pull tabs as the battery springs free effortlessly.

    • 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.

      • To compare Apples to Apples, the iPhone 7 featured a 7.45 Wh battery.

      • And for reference, the similarly-spec'd Galaxy S8 packs a 11.55 Wh battery.

    • 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.

    • 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.

    • 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!

      • We suspect that the newly colored Lightning port could be made of a heat-transferring plastic to allow for safer fast-charging. (Or, it could just be color-matched to the chassis.)

      • Next: a strange interconnect/antenna cable over the speaker.

      • Finally: the Taptic Engine nestled in a series of tiny fiddly connectors.

    • 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!

    • Kangaroo-shaped, chicken-flavored snacks aside, we hope you're not jumpy for the iPhone X. Reports say that production could start as late as mid-October—meaning the 8 could be the hardware of choice for early upgraders as well as those in Apple's Upgrade Program.

    • 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

      • Qualcomm MDM9655 Snapdragon X16 LTE modem

      • Skyworks SkyOne SKY78140

      • Avago 8072JD130

      • P215 730N71T - likely an envelope tracking IC

      • Skyworks 77366-17 quad-band GSM power amplifier module

      • NXP 80V18 secure NFC module

    • And on the back side:

      • Apple/USI 170804 339S00397 WiFi/Bluetooth module

      • Apple 338S00248, 338S00309 PMIC, and S3830028

      • Toshiba TSBL227VC3759 64 GB NAND flash storage

      • Qualcomm WTR5975 Gigabit LTE RF transceiver and PMD9655 PMIC

      • Broadcom 59355—Likely an iteration of BCM59350 wireless charging IC

      • NXP 1612A1—Likely an iteration of the 1610 tristar IC

      • Skyworks 3760 3576 1732 RF Switch and SKY762-21 247296 1734 RF Switch

    • Logic board dispatched, we get down to brass tacks plastic bits. Today's bits feature the speaker and barometric vent.

      • As we learned last year, this barometric vent allows your iPhone to accurately gauge your altitude, while maintaining a watertight seal.

    • 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 donut speaker 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!

      • This coil uses an oscillating magnetic field to generate an alternating current. The alternating current is then converted to direct current—the magic juice that fuels the battery.

    • 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 burrito glass sandwich off of the midframe.

      • This isn't what we thought Apple meant when they said the glass was stronger.

    • 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.

      • This side-by-side reminds us of something we recently noted.

    • 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.

    • Once again, the light sensor is covered by a colored filter, which we believe assists the True Tone system.

    • 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!

  3. Considerações finais
    • 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?

Matt Traynor -

It looks like it's the same screen as the iPhone 7, something like the iPhone 5S and SE, maybe?

Universo Técnico - Responder

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 spoelstra -

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
