Inside the Fonepad
Removing the cap at the top of the Fonepad, you have access to the Micro SIM slot, and to a slot that supports MicroSD memory cards up to 32 GiB. Figure 9 shows the device with the cap removed. These are the only internal parts accessible by the user.
In order to see how it looks inside, we removed the back panel of the Fonepad. At the bottom in Figure 10, you can see the motherboard, and the big battery is at the center.
The battery is a Lithium-Polymer model with nominal voltage of 3.7 V and 4270 mAh of capacity, as shown in Figure 11.
