iPhone 14 Pro Battery Replacement Guide: Safe & Easy DIY Steps

Welcome to the iPhone 14 Pro Battery Replacement Guide! When your iPhone 14 Pro starts experiencing signs of aging, such as degraded battery life or unexpected shutdowns, replacing it with a new battery is the most cost-effective way to restore it to full power.

Pre-repair Preparation & Important Warnings

Discharge the Battery: Before starting the repair, make sure to discharge your iPhone's battery below 25%. If a highly charged battery is accidentally punctured during the repair, it could cause a fire or explosion.
Power Off: Turn off your iPhone completely before beginning any disassembly steps.
Safety Tip: If your battery is already swollen, it is highly recommended to hand it over to a professional repair technician for handling.
Glass Protection: If your screen glass is severely cracked, apply clear adhesive tape over the surface. This prevents flying glass shards from causing injury and ensures the suction cup can maintain a strong grip.
Component Organization: Properly organize all removed parts during the repair to ensure they can be returned to their original spots. Pay extra attention to the screws; installing a screw into the wrong hole can easily damage other components.

Phase 1: Opening the Phone

Step 1: Remove the Bottom Screws

Use a Pentalobe screwdriver to remove the two screws located on either side of the charging port.

Step 2: Apply Tape (For Cracked Screen Protection)

If your screen glass is broken, cover the entire screen with clear adhesive tape. This keeps glass fragments contained and provides a smooth surface for the suction cup to adhere to.

Step 3: Heat the Screen Edges

Use a hair dryer to heat the bottom edge of the iPhone for about 1 minute to soften the internal waterproof adhesive.

Step 4: Create a Gap at the Bottom

Fix the suction cup to the center of the bottom edge of the screen.
Pull upward on the suction cup until a very slight gap appears between the screen and the frame.

Step 5: Insert an Opening Pick and Cut the Adhesive

Insert a plastic opening pick into the gap you just created.

WARNING: Do not insert the opening pick deeper than 3 mm to avoid damaging the internal ribbon cables.
Slide the opening pick along the bottom edge to slice through the waterproof adhesive.
Apply heat to the left and right sides of the phone, then slide the opening pick along both edges respectively.
Heat the top edge to slice through the top adhesive.

Step 6: Swing Open the Screen

Open the screen like a book from the right side to the left side (the ribbon cables are located on the left).
Do not completely detach the screen yet. You can prop the screen up against a box at a 90-degree angle to keep it upright.

Phase 2: Detaching the Screen

Step 7: Remove the Internal Metal Bracket

Use a screwdriver to remove the 8 screws securing the metal cable bracket.
Carefully remove the metal bracket using tweezers.

TIP: Be sure to use a magnetic mat to track the placement of each screw. Accidentally driving a long screw into a short screw hole can easily damage the logic board.

Step 8: Disconnect the Battery (Critical Step)

Use the tip of an insulated spudger to pry up and disconnect the battery connector from the logic board.

Step 9: Disconnect the Screen and Sensors

1. Use the spudger to pry up and disconnect the screen cable connector.

2. Use the spudger to pry up and disconnect the sensor cable connector.

Step 10: Separate the Screen

Now, you can completely separate the screen assembly and place it in a safe location.

Phase 3: Removing the Loudspeaker & Taptic Engine

To safely and conveniently remove the adhesive strips and take out the battery, it is highly recommended to first remove the bottom loudspeaker and the Taptic Engine. If you are experienced, you may also attempt to dissolve the adhesive using high-concentration isopropyl alcohol and pry the battery straight out.

Step 11: Remove the Bottom Loudspeaker

Unscrew the four Phillips screws securing the loudspeaker.
Carefully lift and remove the loudspeaker from the phone.

Step 12: Remove the Taptic Engine

14 Use a spudger to disconnect the Taptic Engine ribbon cable from its socket.

2. Remove the three screws securing the Taptic Engine.

3. Lift the Taptic Engine straight out of the phone.

Phase 4: Removing the Old Battery

Step 13: Pull Out the Battery Adhesive Strips

Use blunt tweezers to carefully peel back the black pull-tabs at the top and the bottom of the battery adhesive strips.
Grip the pull-tab and pull the strip outward, keeping the angle as flat and parallel to the phone as possible. Pull slowly and at a constant speed.
The strip will stretch. Keep pulling slowly until the entire strip is completely drawn out from beneath the battery.

Step 14: Handling Broken Adhesive Strips (Alternative Method)

If an adhesive strip breaks and cannot be retrieved with tweezers, NEVER pry the battery with sharp metal tools!
Apply a few drops of high-concentration isopropyl alcohol into the gaps around the battery. Tilt the phone slightly to let the alcohol dissolve the adhesive.
Insert a plastic spudger or a plastic opening card underneath the battery from the bottom, gently pry up the old battery, and remove it.

Phase 4: Installing the New Battery & Reassembly

Clean off any residual adhesive inside the phone chassis using isopropyl alcohol (90% or higher) and a microfiber cloth, ensuring the surface is clean and flat.
Place the new battery into its original position.
Apply the new frame waterproof adhesive. Before peeling off its final protective film, reconnect the screen and battery, then power on the phone to perform a functionality test.
Once everything tests working correctly, power off the phone again.
Reinstall the cable protection bracket and tighten the screws.
Peel off the protective film from the frame waterproof adhesive. Align the top edge of the screen with the top edge of the phone chassis, then press down firmly along the sides.
Reinstall and tighten the two P2 Pentalobe screws at the bottom.
