iFixit has released a full teardown video of the 10th generation iPad.
Inside the tablet is a 7606 mAh battery, consisting of two cells and a new board with an A14 processor.
Interestingly, the front-facing camera sits horizontally where the iPad Air and Pro wirelessly charge the 2nd generation Apple Pencil. But because of the camera, it had to be removed, so the tablet only supports the first Apple Pencil.
The new iPad also features expandable battery pull tabs like the iPad Air and mini. They make it easy to remove the battery and replace it. In older batteries, iPads are completely glued to the case and are very difficult to remove.
The USB-C port is soldered to a closed circuit board, so if it breaks, the entire module is replaced, which includes the coating and the processor.
