iFixit has completed its teardown of the seventh-generation iPod nano, discovering that the device contains a 220 mAh battery, a Texas Instruments touchscreen controller, and 16 GB of Toshiba NAND flash. The previous generation nano had a 105 mAh battery, which is to say that the new battery has over twice the capacity—though also a much larger screen to power.
Many components within the new nano are soldered to the logic board, including the battery, Lightning connector, and volume controls.
A plastic opening tool and Phillips screwdriver are all that are needed to open the new 1.1-ounce nano.
The device earned a 5 out of 10 repairability score from iFixit, which means it’s easier to repair than the fifth-generation iPod touch, which earned a score of 3..
