… the device has a 1,043 mAh rated lithium-ion battery and 1GB of SK Hynix LPDDR3 RAM. Comparatively, the fifth-generation iPod touch released in 2012 had a 1,030 mAh rated battery and 512MB of RAM.
The teardown also reveals an Apple A8 processor, M8 motion co-processor, Toshiba NAND flash memory, InvenSense MP67B 6-axis gyroscope and accelerometer, a Bluetooth and Wi-Fi module, and Broadcom and Texas Instruments touchscreen controllers.
iFixit rates the new iPod touch received a relatively low repairability score of 4/10, (with 10 being the easiest to repair.) They cite the following as factors contributing to the low score:
While very difficult, opening the case and replacing components is not impossible.
The battery is adhered with pull tabs that should aid in battery replacement.
Many components are soldered together, requiring either a very difficult or a very expensive repair if any one part breaks.
There are no external screws. Instead, a combo of clips and adhesive makes it difficult to open the case.
Ribbon cables connected to the logic board run over the top and connect on the bottom, making it difficult to remove the board or disconnect the cables.
