To begin, we will unhook the straps to work with greater comfort.

We remove the four Torx screws (T3) that hold the back cover, and with the help of a fine tool we will unhook it.

We remove the two Phillips screws (PH # 00) that hold the shield that covers the battery connectors and the flex that is in the back case, and once the shield is removed, we will disconnect both connectors.

To finish we only have to remove the battery from the housing that we have to replace.
