There's an adorable plastic pull tab underneath the battery. It's likely there for battery removal, but we aren't sure it's up to the task.

It seems the adhesive holding down the battery is much too strong for the feeble pull tab to break through.

Forgoing the tab in favor of some spudgering, we're able to pry the 3.7 V, 0.8 Wh, 220 mAh battery off the back of the display assembly.

0.8 Wh is more than twice that of the iPod Nano 6th Generation's 0.39 Wh rating.

By now, we are getting pretty anxious to pull out the logic board and get a look at what makes this Nano tick.

• Alas, with all of the peripherals both soldered to the board and adhered/screwed to the case, we're still a couple steps away.

We're able to unscrew the bracket securing the volume buttons to the rear case and pull out the button cable.

Putting Bluetooth 4.0 in the iPod Nano means putting a Bluetooth 4.0 antenna in the iPod Nano.

• We found this Nano's Bluetooth antenna easy to remove with a plastic opening tool—provided you've already got the case open.

Bluetooth connectivity in the Nano allows you to access your music wirelessly with Bluetooth-enabled speakers, headphones, and car stereos.

After enough poking and prying to earn ourselves certification as plastic surgeons, we finally gently yank out the logic board!

As in the iPod Touch 5th Generation, many of the important components—including the battery, Lightning connector, and volume controls—are soldered to the logic board.

With the logic board gone, the rear case is left all alone with no friends to keep it company. It's not easy being green, you know.

Pulling out the logic board really feels like pulling out the entire iPod—the battery, button cable, Lightning connector, and headphone jack all come with it.

On the flip-side we found an intriguing fibrous tape covering the EMI shields on the ICs. It's probably there to insulate against contact with the rear case.

A rundown of the ICs on the logic board:

• Apple 338S1099
• Broadcom BCM2078KUBG Bluetooth + FM radio
• NXP Semiconductors 1609A1
• 75203 23017
• 75292 98820

Even more ICs:

• Toshiba THGBX2G7D2JLA01 128 Gb (16 GB) NAND flash
• Texas Instruments 343S0538 touchscreen controller
• Apple 338S1146
• 339S0193

iPod Nano 7th Generation Repairability: 5 out of 10 (10 is easiest to repair).

An easy-to-open case only requires unscrewing two screws and a plastic opening tool.

Only standard Phillips #00 screws are used—no security or pentalobe.

The LCD and digitizer glass are not fused together, allowing replacement of either component separately.

"External" screws hidden behind the antenna mean less adhesive holding down the display assembly.

The battery, Lightning connector, button cable, and headphone jack are all soldered to the logic board.

The battery is adhered to the back of the display assembly.
