Everyone knows that Fall is the season for Apples, and they're finally starting to drop. We scooped up the fresh new iPad Mini 4, rinsed it off like Mom taught us, and took it straight to the cutting board. Follow along to find out what the power of an iPad Air in an even more compactified package looks like. It's teardown time!

We're just getting warmed up, so don't miss a teardown! Follow us on Facebook, Instagram, or Twitter for the latest teardown news.

This teardown is not a repair guide. To repair your iPad mini 4 Wi-Fi, use our service manual.

  1. It's thinner. It's lighter. It's powerful-er. What else is it? Here's what we know from Apple: Fully laminated, 7.9-inch (diagonal), 2048x1536 LED-backlit Multi-Touch display with IPS technology Apple A8 SoC with 2nd-generation 64‑bit architecture + M8 motion coprocessor
    • It's thinner. It's lighter. It's powerful-er. What else is it? Here's what we know from Apple:

    • Fully laminated, 7.9-inch (diagonal), 2048x1536 LED-backlit Multi-Touch display with IPS technology

    • Apple A8 SoC with 2nd-generation 64‑bit architecture + M8 motion coprocessor

    • 8 MP iSight camera + 1.2 MP FaceTime HD camera

    • Wi‑Fi (802.11a/​b/​g/​n/ac) with dual channel (2.4 GHz and 5 GHz) and MIMO support + Bluetooth 4.2

    • 19.1 Wh rechargeable lithium-polymer battery

    • Three-axis gyro + accelerometer + ambient light sensor

    • And a brand new model number: A1538

  2. New Mini, new look. We lined up our new (gold) Mini 4 against our old (space gray) Mini 3, and flashbacked to our iPad Air 2 teardown. These are all the same changes! The 6.1 mm thick iPad Mini 4 shaves 18% off the 7.5 mm Mini 3. Many speaker holes are consolidated into fewer.

    • The 6.1 mm thick iPad Mini 4 shaves 18% off the 7.5 mm Mini 3.

    • Many speaker holes are consolidated into fewer.

    • The dual rear-facing microphones move to surround the iSight camera, taking up the home of the now-defunct rotation lock slider.

    • And lastly, that uniform gold color hasn't changed, so your devices can still coordinate, for now (anyone remember the iPhone 5's sort-of blue color?)

  3. As always, our friend iOpener is on hand to melt hearts and adhesive everywhere. <3 iOpener. Despite the rather brief introduction at Apple's event earlier this month, the Mini 4 is packing a pretty major overhaul—including the same fully laminated screen tech we've seen in the iPad Air 2. This is part of what makes the Mini 4 18% thinner than the Mini 3—but it's also more expensive to fix when you drop it.

    • With the adhesive softened, our tried-and-true method of suction cup and opening picks prevails once more. We're on our way inside this critter.

    • As if the fused display wasn't enough of a hint—this is looking more and more like a miniature iPad Air 2 by the minute.

    • Adhering the glass and display together gives a little more rigidity to this Mini—enough to ditch the huge metal shield plate that has traditionally lived behind the LCD.

    • One feature we're glad the Mini has retained: an easily disconnected battery. We'll pop that guy first, without having to bust out our isolation pick (necessary for full-sized iPads).

  5. Saucer Screen separation complete. Besides sealing the display to the glass, there aren't any major changes—the Mini 4 sports the same 2048 x 1536 pixels (326 ppi) as its predecessor. Last year's update to the Mini series brought a single new feature, as a bit of a teaser of what was to come today: Touch ID. As such, not much there has changed, and the bracket and assembly look about the same as in the iPad Mini 3.

    • The other new feature on the Mini 3 was dual blobs of hot glue to hold the button assembly down. That particular repair-hampering detail returns as well.

    • The Touch ID cable is now integrated into the display cable, like on the Air 2 (and unlike on the Mini 3).

  6. All right kids, it time to play Spot the Differences! The now-discontinued iPad Mini 3 on the left faces off against the contender, the new Mini 4 (right). Not only is the battery thinner and of lesser capacity, it's now a single cell, instead of two.

    • Not only is the battery thinner and of lesser capacity, it's now a single cell, instead of two.

    • The lower right antenna now lives in the upper right. We'll have to tear into an LTE version to see what that means for that.

    • The FaceTime camera assembly is seriously slimmed down.

    • Plastic spacers fill in the gaps in the Wi-Fi logic board on the Mini 4 (perhaps to provide some more support for the display).

  7. This iPad is some kind of Mini/Air hybrid—half its antennas on the top, like an Air, half on the bottom like a standard Mini. The &quot;right&quot; antenna moved from its customary speaker spot, to the right of the rear-facing camera.

    • The "right" antenna moved from its customary speaker spot, to the right of the rear-facing camera.

    • This is probably a space saving measure, but maybe this Mini is secretly a flounder. º3º

  8. Beauty is in the eye of the beholder, and these beholders have some pretty nice specs. No longer the red-headed stepchild of the iPad line, the Mini 4 inherits the 8 MP iSight camera from the iPad Air, while retaining the familial 1.2 MP FaceTime camera. Gone also is the front-facing camera's plastic housing. Looks like Apple engineers are steadfastly streamlining the design in the Air's direction.

    • Broadcom BCM5976 digitizer controller

    • Texas Instruments 343S0583, as seen on the iPad Air 2

  11. iPad Mini 4 Repairability: 2 out of 10 (10 is easiest to repair). The battery is still not soldered to the logic board.
    • iPad Mini 4 Repairability: 2 out of 10 (10 is easiest to repair).

    • The battery is still not soldered to the logic board.

    • The LCD and front panel glass are now fused together. This slightly simplifies the opening procedure.

    • The fused front panel also increases the cost of repairing a cracked screen, and increases risk of damage to the LCD when opening.

    • The Lightning connector is soldered to the logic board, so don't bend its pins.

    • Gobs of adhesive hold everything in place making all repairs more difficult.

    • Removing the home button is a tough but required job for display replacement if you want to keep Touch ID functionality.

Thank you for putting up this tear down! I've just picked up an iPad mini 4 and am having some trouble with an interim third party case triggering wake/sleep. Where is the magnet sensor in this iteration of the mini? And do you know its polarity? I'm thinking I might be able to fix this myself with a carefully placed, weak magnet.

Cheers,

Noah

What about the home button assembly? I only need this part. Or maybe a wiring diagram so I can make a Ipad Mini 3 home button wiring work, just to be able to click.. I don't need the fingerprint reader.

So the LCD is the same in the mini 3 and mini4, but home button is different. Can you use a ipad mini 3 digitizer on a ipad mini 4? Thanks so much for this, it's so helpful!

Did you ever get the home button to work

nettech207 -

Not at all because the 3 digitizer is smaller compared to the 4 due to the increase in height that the mini 4 has so it will not work at all and it will be to small

I have an issue with repairing iPad mini 4 screen's I have repaired many iPads but the mini 4 is acting odd. I replaced the screens and swap over the home button and solder the little cable thing thats on the left side of the home button. My issue is the power button won't work any more. But oddly it will power on and power off the unit but not lock or wake up the unit. I've repaired two of these unit and both have this same exact issue.
