We begin by removing the sim tray to be able to remove the battery cover

With the help of an opening tool, we insert it between the screen and the housing and extract the battery cover using a gentle lever.

With a Phillips-type screwdriver (PH # 00) we extract the eleven screws that hold the intermediate casing and remove it with a fine plastic tool

With a thin plastic tool we disconnect the flex from the battery for greater security.

With a fine tool, we peel off the adhesive from the battery, once it is detached, we pull it to gradually detach the battery from its base and be able to remove it.
