iFixit has completed its iPad Mini Retina display teardown and done things to a new iPad you'd never dream of doing. After mercilessly opening it with suction cups and guitar picks, the team discovered the following:
- While "mini" tends to denote added cuteness with compromised functionality, this Mini packs a resolution of 2048 x 1536—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.
- Holy holes, Batman! What's this? Wi-Fi-only Minis of yesteryear featured a blank expanse at the end of the logic board—just a flat space where the cellular chips would be. This Retina Mini's board has a nifty cutout instead.
Here's the details on the chips inside the new iPad mini:
- Apple A7 APL0698 SoC—The 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
