iFixIt iPad Mini Retina Display Teardown

iFixit Chief Information Architect Miroslav Djuric says the new iPad mini with Retina Display is a worthy alternative to the iPad Air and successor to last year’s iPad mini (still available for $299), but it’s like them a nightmare to repair.

Djuric writes:

The mini is no longer the runt of the litter, having gained the snappy A7 processor, M7 coprocessor, and a 2048 x 1536 pixel display at an impressive 326 ppi. Unfortunately, the newest member still carries the familial low repairability.

Last week, Amazon’s 8.9 Fire HDX tablet wowed us with its easy, adhesive-free opening procedure. Only 0.3 mm thicker than the iPad Air, the Fire HDX seemed to handily disprove the argument that repairability and thin design are mutually exclusive. Coincidentally, the iPad mini is 0.3 mm thicker than it was last year, but the new Retina mini uses its extra girth to support a flashy new Retina Display, leaving repairability woefully unchanged.

In fact, the updated specs mean little as far as internal architecture is concerned. With very similar construction and inhibitors to repair, this mini earns the legacy 2 out of 10 repairability score.

Teardown highlights:

While “mini” tends to denote added cuteness with compromised functionality, this mini packs a resolution of 2048 x 153 – just like the iPad Air. The same resolution in a smaller screen means enhanced pixel density – 326 ppi on the Mini versus 264 ppi on the Air.

Our little Retina has an LG display, powered by a Parade DP675 LCD driver, similar to the DP655 found in the iPad Air.

To the surprise of no one, we find affixed dual Broadcom BCM5976 touchscreen controllers – much like we’ve seen in a host of recent Apple products including the iPad Air and iPhones 5 and 5s.

The battery weighs in at 3.75 V, 24.3 Whr, 6471 mAh – a huge bump over the 16.3 Whr battery seen in the previous mini. It seems we’ve found the source of the Retina’s thicker skin; as Apple still pegs the battery life at 10 hours, we suspect the extra juice is being funneled into the swanky new display.

Instead of glue, the logic board is seated over a couple of screwposts for security – a mini win for repairability! The only adhesive is a bit under the panhandle full of connectors, and a solid swath under the Lightning connector cable.

Wi-Fi-only minis of yesteryear featured a blank expanse at the end of the logic boardjust a flat space where the cellular chips would be. This Retina mini’s board has a nifty cutout instead.

We got the jimmies for some chip jimmies:
• Apple A7 APL0698 SoCThe same part number as seen on the iPhone 5s
• Within the A7 package is Elpida F8164A1PD 1 GB LPDDR3 DRAM
• NXP LPC18A1 (Apple M7 Motion Co-Processor)
• Toshiba THGBX2G7B2JLA01 16 GB NAND flash
• B334 STMicro MEMS accelerometer/gyroscope, the same as seen in the iPad Air
• Apple 338S1213 Cirrus Audio Codec
• Apple 338S1199 – likely audio amplifiers similar to those found in the previous iPad mini
• Apple 343S0656-A1 – likely a variant of the Dialog PMIC found in the iPad Air
• Fairchild Semiconductor FDMC6676BZ and FDCM6683 MOSFETs
