Introduction
Follow this guide to replace the Taptic Engine in your iPhone 6s. The Taptic Engine is the iPhone's vibrating and haptic feedback motor. If your phone isn't vibrating or produces a rattling sound when it does, replacing the Taptic Engine can remedy your issues.
What you need

Squeeze the cups together to apply suction to the desired area.
-
-
-
Pull the blue handle forwards to lock the arms.

If you don't have an Anti-Clamp, follow the next three steps to use a suction handle.
-
Apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.
-
-
-
Apply a suction cup to the lower left corner of the display assembly.
-
Take care not to place the suction cup over the home button.
-
-
-
Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
-
-
-
Place the flat edge of a spudger into the gap between the screen and rear case, directly above the headphone jack.
-
-
-
-
Twist the spudger to widen the gap between the front panel assembly and the rest of the phone.
-
-
-
Insert the flat end of the spudger on the left side of the phone, between the display assembly and rear case.
-
Slide the spudger up the side of the phone to separate the adhesive and pop the clips free.
-
-
-
Remove the spudger and reinsert it on the bottom edge, where you pried the phone open.
-
Slide the spudger to the right, along the bottom edge of the phone.
-
-
-
Slide the spudger up the right side to continue separating the adhesive and popping the display clips free from the iPhone.
-
-
-
Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel as a hinge.
-
Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.
-
Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.

Tool used on this step:Magnetic Project Mat$19.95
-
Remove two Phillips screws securing the battery connector bracket, of the following lengths:
-
One 2.9 mm screw
-
One 2.2 mm screw
-
-
-
Use the point of a spudger to disconnect the battery connector by prying it straight up from the logic board.
-
-
-
Push the battery connector away from the logic board until it stays separated from its socket, so as to avoid any accidental connection to the battery while you work.
