While it's usually better not to take your iPhone apart, there may come a time when you need to remove the battery, something you can do yourself if the warranty has already expired. This procedure is tricky and varies by version, but if you're a bit handy, you can get it done without too much trouble. Keep reading to learn more.
Method 1 of 3: iPhone 5
Step 1. Remove the bottom screws
Use a Phillips screwdriver to remove the 3.6mm screws on the bottom of your iPhone.
These screws can be found right next to your "Lightning" connector
Step 2. Attach a suction cup to the front of your phone
Press the suction cup against the screen, just above the "Home" button. Apply enough pressure to secure it.
It is necessary for the suction cup to be secure to hold the front half up while you try to release it from the bottom
Step 3. Press the back panel down
Lift the suction cup with one hand while pulling the back panel down with the other. Once a gap is large enough, slide a plastic tool in between to pry the two halves apart.
- While separating the two halves, apply firm, even pressure. The case of an iPhone 5 is noticeably tighter and difficult to open.
- Continue to pull on the suction cup while working with the plastic tool.
- You will notice several clips that hold the front panel to the back panel as you do this. You have to loosen these clamps first.
- Now only loosen the bottom and the sides first.
Step 4. Open the front panel
After the side and bottom have been detached, open the front cover so that it is at a 90-degree angle to the back.
Do not separate the front from the back yet. First there are ribbon cables that you need to remove
Step 5. Remove the holder from the cable
Using the Phillips screwdriver, loosen the screws around the cable holder. Then use your fingers to remove the cable holder connected to the circuit in the rear panel and connected to the front.
There are a total of three screws that you need to remove: two 1.2mm screws and one 1.6mm screw
Step 6. Disconnect the mounting cables
Use the plastic tool to disconnect the cables from the front camera and those from the sensor, digitizer and LCD screen. Lift them up and to the side with the plastic tool.
Now you can completely remove the front cover without damaging anything
Step 7. Remove the battery connector holder
Loosen the two screws along the metal holder for the battery connector. This holds the battery connector in the circuit. After removing the screws, you can remove the connector holder with your fingers.
There are two screws that you will need to remove: a 1.8mm screw and a 1.6mm screw
Step 8. Lift up the battery connector
Slide the tip of your plastic tool under the battery connector, lifting it up and removing it from the socket in the circuit.
Be very careful when doing this. Remove only the battery connector, not the socket itself
Step 9. Push up the battery to remove it
Place the edge of the plastic tool between the battery and the back panel of the phone. Working along the right side, pry up the battery at several points to remove it.
- Work carefully to avoid damage to the phone or battery.
- If necessary, remove the plastic from the battery that secures it to the back of the iPhone.
- You are done.
Method 2 of 3: iPhone 4 and 4s
Step 1. Remove the screws on the back
Use a small (pentalobe) screwdriver to loosen the two small screws on the bottom of the iPhone. Set them aside and keep them in a safe place.
These screws are both 3.6mm long and are located on either side of the dock connection port
Step 2. Slide the back cover up to remove it
Hold the iPhone with both hands and slide the back cover up with your thumbs to remove it. Keep your fingers on the screen while doing this.
- You will need to apply some force to shift the rear. To reduce the risk of damaging the screen, apply force with your thumbs and push not in the middle, but at the top or bottom of the back panel.
- The panel will shift approximately 2mm.
- If the back is slid up, you can open it from the side and remove it from the front. If you are unable to lift the panel with your fingers, you can also use a suction cup to lift it.
Step 3. Remove the screws around the battery
Use a #00 Phillips Phillips screwdriver to remove the two screws around the battery. These screws secure the battery connector to the logic board.
- Note: the top screw is shorter than the bottom one.
- On some of the iPhone 4 models, you only need to replace one screw.
Step 4. Lift up the battery connector
Slide the tip of your plastic tool under the battery connector to remove the circuit.
- You can also remove the small clip under the battery connector before removing the connector itself. You do this with the same plastic tool. If you don't do this, you risk the clamp coming loose when you remove the connector.
- Be careful not to accidentally remove the socket. Just remove the connector.
Step 5. Lift the battery
Pry the tip of your plastic tool under the battery and gently pry it up to remove the battery.
- Work carefully. The battery is held in place by glue, so you will have to use quite a bit of directed force to remove it.
- If necessary, remove the plastic from the battery that secures it to the back of the iPhone.
- Don't get too close to the top of the iPhone, because that's where the volume cables are.
- This completes the procedure.
Method 3 of 3: iPhone 3
Step 1. Remove the two bottom screws
Use a Phillips #00 Phillips screwdriver to remove the 3.7mm screws on the bottom of the phone. Set them aside in a safe place.
The two screws are located on either side of the dock connector
Step 2. Lift open the front panel
Place a firm suction cup on the screen, just above the "Home" button. If it's firmly in place, lift the screen while holding the bottom of the iPhone with your other hand. The front panel should come off like this.
- You will have to use quite a bit of force to lift the front panel by the suction cup. There is a rubber gasket between the edge of the front panel and the back panel so that the two halves fit tightly together.
- Move the suction cup back and forth to make it easier to release the panel while lifting.
- You can also use the plastic tool to loosen the bottom from the top.
- Do not remove the front panel completely, as it is still connected to the bottom with some cables. Tilt it at a 45-degree angle to the bottom.
Step 3. Disconnect the ribbon cables
While holding the front open with one hand, use the other to disconnect the black ribbon cables "1, ""2" and "3" with the plastic tool.
- Work with the tool from the left. If you do this from the right, you can damage the connectors of the cables.
- Lift cables 1 and 2 to remove the connectors. Cable 3 will rotate up approximately 90 degrees.
- Slide the cables off the connectors. You should now be able to remove the front from the back.
Step 4. Remove the SIM tray
Using a SIM eject tool, push into the hole next to your phone's headphone jack. Keep pressing until the SIM card is ejected, then remove it with your fingers.
- If you don't have a SIM eject tool, you can also use a paperclip.
- You can also remove this tray at the very beginning, if that's easier for you.
Step 5. Disconnect link cables 4, 5 and 6
Slide your plastic tool under each connector to push them up and open them.
- If you have an iPhone 3GS, you will see a ribbon cable "7" that you also have to disconnect.
- Remove the "Do not remove" sticker to reveal one of the screws on the bottom of the back panel.
Step 6. Remove the screws around the phone and battery
You will see eight screws: five 2.3mm screws, two 2.3mm screws and one 2.9mm screw.
- The first five 2.3mm screws are partially threaded and secure the logic board to the rear.
- The two 2.3mm screws are fully threaded and secure the logic board to the camera.
- The 2.9mm screw is located under the "Do not remove" sticker.
Step 7. Remove the camera
Slide the plastic tool under the camera. Apply even pressure to push the camera up and out.
Note that you cannot remove the camera completely. The bottom remains attached to the logic board
Step 8. Pry the bottom of the logic board
Slide the plastic tool under the logic board on the side of the dock connector. Gently lift the logic board and slide it out toward the dock connector, removing it completely.
You will see a small, gold-colored tab on the logic board. It is quite delicate and can break easily, so be extra careful
Step 9. Lift out the battery
Slide the plastic tool under the battery. Lift the battery to remove it.
- Adhesive holds the battery on the back. The result may be bending or otherwise damaging the battery if you are not careful when removing it.
- You can use the plastic tab to remove the battery, but this increases the risk of the battery bending.
- If necessary, you can try warming the back with a hairdryer on the lowest setting. This can weaken the adhesive, making it easier to remove the battery.
- The procedure is completed with this step.
Keep any screws you removed in a safe place while working. If possible, also keep the screws separated from each other so that it is easy to distinguish which screws go where
- Turn off your iPhone before removing the battery. Otherwise, you may get a shock and your phone may be damaged.
- Understand that removing the battery from your iPhone will void your warranty. If you still have a warranty on your phone, it is better to have the battery removed by experts for free. If not, removing the battery yourself will be cheaper than having it repaired.
- Only use a plastic tool to open the device. Metal tools can damage your phone.
