The iPad 3's battery is quick and needs to be replaced if it expands.

First of all, a strong double-sided tape is attached to the part filled with red, so i warm it with a heat gun or a dryer and float the double-sided tape.
The liquid crystal (touch panel) is not secured with screws and is installed only with strong double-sided tape.
