How to Change an iPhone 14 Battery

What You’ll Need

Replacement iPhone 14 battery (with adhesive strips)
Pentalobe screwdriver (P2) for the bottom screws
Phillips screwdriver (#00 or #0) for internal screws
Suction cup (or iOpener / heat gun)
Plastic opening picks and spudger
Tweezers
Y000 tri-point screwdriver (for the battery connector cover screws)
Isopropyl alcohol (90%+), if needed to soften adhesive
New adhesive strips or double-sided tape for sealing

Step-by-Step

Power off and prepare. Turn off the iPhone 14 and remove the two pentalobe screws at the bottom edge (next to the charging port). Keep them safe.
Heat the display edges. Apply a heated iOpener or a heat gun (on low) along the bottom and sides of the screen for about 1–2 minutes. This softens the adhesive. Do not overheat—the screen can be damaged.
Open the display. Place a suction cup near the bottom edge of the screen and pull up gently to create a small gap. Insert a plastic pick into the gap and slide it along the sides to release the adhesive. Work slowly and carefully—the display is fragile.
Prop open the display. Once the display is loose, tilt it open like a book (hinge at the top). Rest it on a stable object or have someone hold it. Do not pull it far—the flex cables are still attached.
Remove the display shield. Use the Y000 screwdriver to remove the screws on the metal bracket covering the display connectors. There are several screws of different lengths—note their positions. Lift the bracket off with tweezers.
Disconnect the display. Using a spudger, gently pry up the three connectors: the battery, the display, and the touch. The battery connector is the one on the right side. Disconnect the battery first to cut power, then the other two. Remove the display assembly completely and set it aside.
Remove the battery connector cover. Find the metal plate over the battery connector (near the bottom right of the logic board). Remove its screws (Y000) and lift the plate off.
Disconnect the battery. Use a spudger to gently pry up the battery connector from its socket. Be careful not to damage the socket.
Remove the old battery. The battery is held by adhesive strips. Pull the release tabs (if present) slowly and evenly. If they break, use a plastic card or apply isopropyl alcohol around the edges to loosen the adhesive. Never pry with metal tools—you could puncture the battery. Once free, lift the battery out.
Install the new battery. Place the new battery in position, but do not press down firmly yet. Connect the battery connector to its socket, then replace the metal cover and screws. Press the battery down to secure it.
Reassemble. Reconnect the display and touch connectors, then the battery connector (if you disconnected it earlier). Replace the display shield and its screws. Close the display, press along the edges to reseal, and reinstall the two bottom screws. Power on and test.

Common Mistakes

Not heating the adhesive enough—forcing the screen can crack it.
Prying the battery with metal tools—puncturing a lithium-ion battery can cause a fire.
Mixing up screws—use a magnetic mat or take photos to remember where each screw goes.
Pulling the display too far—the flex cables are short and can tear.
Skipping the battery disconnect before disconnecting other cables—this can cause a short.

Tips

Work in a clean, well-lit area and keep screws organized.
Use an anti-static wrist strap if you have one.
If the battery adhesive strips break, use a few drops of isopropyl alcohol under the battery and wait a minute—it softens the adhesive without damaging the battery.
Before sealing, test the phone fully: screen, touch, charging, and camera.
If the screen doesn’t sit flush, check for any debris or bent clips.

Troubleshooting

Screen won’t turn on: Recheck all display and battery connectors. Ensure the battery is connected and charged.
Touch not working: The touch connector may be loose or damaged. Disconnect and reconnect it carefully.
Battery percentage not showing: The battery connector may not be fully seated. Reconnect it.
Phone feels hot or battery swells: Stop immediately. If the battery is swollen or hot, it may be damaged—do not continue. Seek professional help.
Adhesive strips broke: Use alcohol to loosen the battery, then gently pry with a plastic card. Never force it.
Screen has gaps: Clean the edges and apply new adhesive strips before closing.

Frequently Asked Questions
