Small Phillips Screwdriver
iPhone 5-Point Pentalobe Screwdriver
iSesamo Opening Tool
Fine Tip Curved Tweezers
Battery Adhesive Strips
Power down your iPhone 6s smartphone.
Remove the two bottom 3.4 mm Pentalobe screws located next to the lightning connector.
Place a suction cup near the home button and pull the iPhone 6s display assembly away from the rear case. Use the iSesamo opening tool to slice through the adhesive and help carefully separate the display assembly from the rear case.
Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices and is held down with adhesive.
The display assembly is still connected to the iPhone by several cables, so don’t try to remove it entirely just yet.
Remove the following 4 Phillips screws securing the metal bracket to the motherboard.
Now use the fine tip curved tweezers to remove the metal bracket and disconnect the iPhone 6s LCD, digitizer and front camera and proximity sensor cables.
Remove the following 2 Phillips screws securing the metal battery connector bracket to the motherboard.
Now, use the fine tip curved tweezers to remove the metal battery connector bracket and then disconnect the battery connector from the motherboard.
Use the fine tip curved tweezers to peel up the edges of the two adhesive strips at the bottom of the iPhone 6s battery.
Grab the end of the first adhesive strip and try to keep the strip flat and wide.
Slowly and gently pull each strip up and away from the iPhone. The strips will stretch to many times the length of the battery- keep pulling until they come out from between the battery and the rear case.
Now, remove the iPhone 6s battery from the rear case.
*To reassemble your device, follow the steps in reverse order.
