Lesson learned about adhesive in this teardown—we go straight to the iOpener in order to get the battery out of its sticky cage.
As always, we are ignoring some kind of warning. This time, it tells us not to remove the battery from the back cover. Apparently, to safely replace your battery you will need a whole back cover assembly.
We don't understand the point of heavily-glued batteries. This kind of planned obsolescence is completely unnecessary.
