Introduction

Use this guide to bring life back to your iPhone 6 Plus with a new battery. If your battery is swollen, take appropriate precautions.

This guide instructs you to remove the front panel assembly; this is intended to prevent damage to the display cables. If you feel comfortable supporting the display carefully while peeling the battery out of the iPhone, you can skip the display removal and go directly to the battery removal steps.

For optimal performance, after completing this guide, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least two more hours. Then use your iPhone until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

You can also use this guide to replace the battery connector bracket.

Video Overview

  1. Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 3.6 mm P2 Pentalobe screws next to the Lightning connector.

    Edit

  2. The next two steps demonstrate using the iSclack, a great tool for safely opening the iPhone 6 Plus that we recommend for anyone doing more than one repair. If you aren't using the iSclack, skip down two steps. If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone 6 Plus. Close the handle on the iSclack, opening the suction cup jaws.

    • The next two steps demonstrate using the iSclack, a great tool for safely opening the iPhone 6 Plus that we recommend for anyone doing more than one repair. If you aren't using the iSclack, skip down two steps.

    • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone 6 Plus.

    • Close the handle on the iSclack, opening the suction cup jaws.

    • Place the bottom of your iPhone in between the suction cups.

    • Position the iSclack's upper suction cup against the display, near the home button.

    • Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.

    • If your display or back glass is badly cracked, covering it with a layer of clear packing tape may help the suction cups adhere. The iSclack also includes two pieces of tape for this purpose.

    Edit

  3. Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case. The iSclack is designed to safely open your iPhone enough to separate the pieces, but not enough to damage any of the display cables.

    • Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case.

    • The iSclack is designed to safely open your iPhone enough to separate the pieces, but not enough to damage any of the display cables.

    • Peel the two suction cups off your iPhone.

    • Skip the next three steps and continue on to Step 7.

    Edit

  4. If you don't have an iSclack, use a single suction cup to lift the front panel:

    • If you don't have an iSclack, use a single suction cup to lift the front panel:

    • Press a suction cup onto the screen, just above the home button.

    • Be sure the cup is pressed securely onto the screen to get a tight seal.

    • If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

    Edit

  5. While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.

    • While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.

    • Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

    • Using a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while continuing to pull up with the suction cup.

    • There are several clips attaching the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

    Edit

  6. Pull the plastic nub to release the vacuum seal on the suction cup. Remove the suction cup from the display assembly.

    • Pull the plastic nub to release the vacuum seal on the suction cup.

    • Remove the suction cup from the display assembly.

    Edit

  7. Pull the home button end of the front panel assembly away from the rear case, using the top of the phone as a hinge. Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone. Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.

    • In a pinch, you can use an unopened canned beverage to hold the display.

    Edit

  8. Several clips along the top edge of the front panel form a partial hinge, allowing the front panel assembly to swing open like a book. During reassembly, align the clips just below the top edge of the rear case. Then, slide the front panel upward until its top edge is flush with that of the rear case.

    • Use a clean fingernail or the edge of an opening tool to gently pry the battery connector up from its socket on the logic board.

    • Take care to only pry up on the battery connector, and not the socket on the logic board. If you pry up on the logic board socket, you may break the connector entirely.

    Edit

  13. Remove the following Phillips screws securing the front panel assembly cable bracket:

    • Remove the following Phillips screws securing the front panel assembly cable bracket:

    • Three 1.2 mm screws

    • One 1.5 mm screw

    • One 2.9 mm screw

  20. Peel back the first battery adhesive tab from the bottom right edge of the battery.

    • Peel back the first battery adhesive tab from the bottom right edge of the battery.

    • Use your fingers or blunt tweezers. Be extra careful when working near the battery; puncturing a lithium-ion battery can release dangerous chemicals and cause a fire.

    Edit

  21. Try to keep the strips flat and unwrinkled during this procedure; wrinkled strips will stick together and break instead of pulling out cleanly. Very slowly, pull and stretch one adhesive strip away from the battery, toward the bottom of the iPhone.

    • Try to keep the strips flat and unwrinkled during this procedure; wrinkled strips will stick together and break instead of pulling out cleanly.

    • Very slowly, pull and stretch one adhesive strip away from the battery, toward the bottom of the iPhone.

    • Allow the strip to stretch out before pulling any harder. If you can't feel it stretching, ease up, or it will break.

    • Pull at as low of an angle as you can without snagging the adhesive strip on any of the components along the lower edge of the phone.

    • Don't press down on the battery as you pull the strip.

    • The strip will stretch to many times its original length. Continue pulling slowly until it releases and slips out from underneath the battery.

    • If the battery adhesive tabs break during the removal process, use your fingers or blunt tweezers to retrieve the remaining length of adhesive, and continue pulling.

    • If any of the adhesive strips break underneath the battery and cannot be retrieved, try to remove the remaining strips, and then proceed as instructed below.

    Edit

  22. Peel back the second battery adhesive tab from the other side of the battery. Again, pull and slowly stretch the adhesive tab to slide it out from between the battery and the rear case.

    • Peel back the second battery adhesive tab from the other side of the battery.

    • Again, pull and slowly stretch the adhesive tab to slide it out from between the battery and the rear case.

    • Continue pulling the adhesive tab until it releases completely from the battery. If it breaks, try to retrieve the remaining length and continue pulling, or proceed as instructed below.

    Edit

  23. Peel back the final battery adhesive tab from the bottom edge of the battery. Gently pull the battery adhesive tab upward and away from the battery, allowing the adhesive strip to slowly slide out from between the battery and the rear case. Place one hand over the battery as the final strip comes out, or it may fling the battery out of the iPhone. Continue pulling until the final strip comes free from the iPhone.

    • Peel back the final battery adhesive tab from the bottom edge of the battery. Gently pull the battery adhesive tab upward and away from the battery, allowing the adhesive strip to slowly slide out from between the battery and the rear case.

    • Place one hand over the battery as the final strip comes out, or it may fling the battery out of the iPhone.

    • Continue pulling until the final strip comes free from the iPhone.

    • If you removed all three adhesive strips successfully, continue to step 24. Otherwise, if the adhesive breaks off underneath the battery and can't be retrieved, apply a few drops of high concentration (over 90%) 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 the flat end of a spudger to gently lift the battery.

    • Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

    • Do not pry against the logic board, or you may permanently damage your iPhone. Do not pry under the topmost section of the battery, near the volume up button and mute switch, or you may damage the audio controls cable, which is adhered to the rear case just beneath the battery.

    • For alternative methods to unstick the battery, continue with the next step below.

    Edit

  24. If the battery remains stuck to the rear case, prepare an iOpener or use a hair dryer to heat the rear case directly behind the battery.

    • If the battery remains stuck to the rear case, prepare an iOpener or use a hair dryer to heat the rear case directly behind the battery.

    • Then, use a plastic opening tool to gently lift the battery.

    • Overheating the iPhone may ignite the battery.

    • Alternatively, a piece of dental floss may be used to separate the battery from the rear case. A stronger alternative to dental floss is an unwound guitar string, such as a 0.009 E string from a 12-string set.

    • Thread the floss or string underneath one end of the battery and pull side to side in a sawing motion to separate the adhesive.

    Edit

  25. Remove the battery from the iPhone.

    • Remove the battery from the iPhone.

    • If your replacement battery came in a plastic sleeve, remove the sleeve before installation by pulling it away from the the ribbon cable.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

    • Before you adhere the replacement battery, temporarily reconnect the battery connector to the logic board socket. This ensures that the battery is properly aligned in its recess.

    • Adhere the battery, disconnect it, and continue reassembling your device.

    • If your new battery doesn’t have adhesive preinstalled, refer to this guide to replace the adhesive strips.

    • Perform a hard reset after reassembly. This can prevent several issues and simplify troubleshooting.

    Edit
Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
