iPhone 14 Pro Max Battery Replacement

Power off your iPhone before beginning disassembly.

Remove the two 6.8 mm-long pentalobe P2 screws at the bottom edge of the iPhone.

Measure 3 mm from the tip and mark the opening pick with a permanent marker.

Lay overlapping strips of clear packing tape over the iPhone's screen until the whole face is covered.

If you can't get the suction cup to stick in the next few steps, fold a strong piece of tape (such as duct tape) into a handle and lift the screen with that instead.

Pull the blue handle backwards to unlock the Anti-Clamp's arms.

Slide the arms over either the left or right edge of your iPhone.

Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.

Squeeze the cups together to apply suction to the desired area.

Pull the blue handle forwards to lock the arms.

Turn the handle clockwise 360 degrees or until the cups start to stretch.

Make sure the suction cups remain aligned with each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.

Support your iPhone on something sturdy such as a hardcover book so it rests hands-free and parallel to the ground; this makes it easier to work with in the following steps.

Use a hair dryer to heat along the bottom edge of the iPhone. The screen should feel slightly too hot to touch.

Wait one minute to give the adhesive a chance to release and present an opening gap.

Insert an opening pick under the screen's plastic bezel when the Anti-Clamp creates a large enough gap.

Skip the next two steps.

Use a hair dryer or a heat gun to heat the bottom edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

Apply a suction handle to the bottom edge of the screen, while avoiding the very edge of the glass.

Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the frame.

Insert an opening pick into the gap under the screen's plastic bezel.

Use a hair dryer to heat the right edge of the iPhone (the edge with the power button) for 90 seconds or until the screen is slightly too hot to touch.

Slide the opening pick around the bottom right corner of the iPhone to separate its adhesive.

Continue sliding up the right edge of the iPhone until you reach the top right corner.

Leave the pick in the top right corner before continuing.

Use a hair dryer to heat the top edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

Insert your pick underneath the top right edge of the phone. Slide it around the top-right corner and half way across the top edge stopping right before the earpiece speaker cut-out.

Use a hair dryer to heat the left edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

Insert a second opening pick in the bottom left corner of the iPhone.

Twist both picks simultaneously until the left edge clips release.

Rotate your iPhone so the right edge faces you.

Open your iPhone by swinging the screen up from the right side, like the front cover of a book.

Lean the screen against something to keep it propped up while you're working on the phone.

Use a Y000 screwdriver to remove the eight screws securing the battery connector cover:

Six 1.3 mm-long screws

One 1.6 mm-long screw

One 1.9 mm-long screw

Grasp the connector cover with a pair of tweezers and slide it downwards to clear the flex cables.

Remove the connector cover.

Use the pointed end of a spudger to disconnect the battery cable by prying the connector straight up from its socket.

Bend the connector slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

Use the pointed end of a spudger to disconnect the first display cable by prying the connector straight up from its socket.

Use the pointed end of a spudger to disconnect the second display cable by prying the connector straight up from its socket.

Remove the screen.

Use a Phillips driver to remove the four 1.5 mm-long screws securing the loudspeaker:

Three smaller-headed screws

One larger-headed screw

Use the flat end of a spudger to pry up and loosen the loudspeaker from the bottom right corner of the phone.

Use a pair of tweezers to grab the loudspeaker.

Tilt the loudspeaker to separate it from the adhesive-backed strip that leads to the Taptic Engine.

Remove the loudspeaker.

Use a spudger to disconnect the Taptic Engine by prying the connector straight up from its socket.

Use a Phillips screwdriver to remove two screws securing the Taptic Engine:

One 1.8 mm-long screw

One 2.3 mm-long screw

Use a standoff screwdriver to remove the 2.9 mm-long standoff screw securing the Taptic Engine.

Use a pair of tweezers or your fingers to remove the Taptic Engine.

Use your fingers or a pair of tweezers to gently peel the adhesive-backed strip off of the Taptic Engine.

Each adhesive strip has a black pull-tab at the end, which is lightly adhered to the edge of the battery.

Use a pair of blunt-nosed tweezers to peel down the two battery adhesive pull-tabs along the bottom edge of the battery.

Grab the first pull-tab with your fingers or wrap it around a spudger and slowly pull it away from the battery, toward the bottom of the iPhone.

Pull hard enough to maintain tension on the strip, but don't force it. Give it plenty of time to stretch and un-stick from under the battery.

Don't press down on the battery. Hold the iPhone firmly by its sides.

Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.

Pull at a low angle so the strip doesn't snag on the edge of the battery.

If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

Grab the second pull-tab with your fingers or the center of a spudger and pull it away from the battery, toward the bottom of the iPhone.

Follow the same procedure as with the previous strip: don't press down on the battery, keep the strip flat and unwrinkled, and pull at a low angle.

If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

Use a pair of blunt-nosed tweezers and an opening pick to peel up the two remaining battery adhesive pull-tabs from the top edge of the battery.

Using the same procedure as before, pull the third tab from underneath the battery. Try not to snag the adhesive on anything.

Pull the remaining adhesive tab using the same procedure. Try not to snag the adhesive on anything.

If you removed all the adhesive strips successfully, skip the next step.

Otherwise, continue with the next step below.

If you're still having trouble removing the battery, apply a few drops of high concentration (90% or higher) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).

Wait about one minute for the alcohol solution to weaken the adhesive.

Use an opening pick or the flat end of a spudger to gently lift the battery.

Remove the battery.
