  1. iPhone 6s Battery Replacement, Pentalobe Screws: étape 1, image 1 de 1
    • 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 3.4 mm P2 Pentalobe screws on the bottom edge of the iPhone, on either side of the Lightning connector.

    • If you don't have an Anti-Clamp, follow the next three steps to use a suction handle.

    • Apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.

    • Heat softens the adhesive securing the display, making it easier to open.

  3. iPhone 6s Battery Replacement: étape 3, image 1 de 1
    • Opening the display on the 6s separates a thin strip of adhesive around the perimeter of the display. If you prefer to replace the adhesive, have a set of new adhesive strips ready before you continue. It's possible to complete the repair without replacing the adhesive, and you probably won't notice any difference in functionality.

    • Apply a suction cup to the lower left corner of the display assembly.

    • Take care not to place the suction cup over the home button.

    • 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.

  4. iPhone 6s Battery Replacement: étape 4, image 1 de 2 iPhone 6s Battery Replacement: étape 4, image 2 de 2
    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

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

    • Pulling too hard may damage the display assembly. Apply just enough pressure to create a small gap between the display assembly and the rear case.

    • If you have any trouble, heat the front of the iPhone using an iOpener, hair dryer, or heat gun until it's slightly too hot to touch. This will help soften the adhesive securing the edges of the display.

  5. iPhone 6s Battery Replacement: étape 5, image 1 de 2 iPhone 6s Battery Replacement: étape 5, image 2 de 2
    • There is a notch on the underside of the display, just above the headphone jack. This is the safest place to begin prying the phone open.

    • Place the flat edge of a spudger into the gap between the screen and rear case, directly above the headphone jack.

  6. iPhone 6s Battery Replacement: étape 6, image 1 de 2 iPhone 6s Battery Replacement: étape 6, image 2 de 2
    • Twist the spudger to widen the gap between the front panel assembly and the rest of the phone.

  7. iPhone 6s Battery Replacement: étape 7, image 1 de 2 iPhone 6s Battery Replacement: étape 7, image 2 de 2
    • Insert the flat end of the spudger on the left side of the phone, between the display assembly and rear case.

    • Slide the spudger up the side of the phone to separate the adhesive and pop the clips free.

  8. iPhone 6s Battery Replacement: étape 8, image 1 de 2 iPhone 6s Battery Replacement: étape 8, image 2 de 2
    • Remove the spudger and reinsert it on the bottom edge, where you pried the phone open.

    • Slide the spudger to the right, along the bottom edge of the phone.

  9. iPhone 6s Battery Replacement: étape 9, image 1 de 2 iPhone 6s Battery Replacement: étape 9, image 2 de 2
    • Slide the spudger up the right side to continue separating the adhesive and popping the display clips free from the iPhone.

  10. iPhone 6s Battery Replacement: étape 10, image 1 de 2 iPhone 6s Battery Replacement: étape 10, image 2 de 2
    • Use the suction cup to open the display, breaking the last of the adhesive.

    • Don't open the display more than 90º, as it is still connected at the top by three cables that may break if stretched.

  11. iPhone 6s Battery Replacement: étape 11, image 1 de 2 iPhone 6s Battery Replacement: étape 11, image 2 de 2
    • Pull up on the nub on the top side of the suction cup to remove it from the front panel.

    • Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel 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.

    • Remove two Phillips screws securing the battery connector bracket, of the following lengths:

    • One 2.9 mm screw

    • One 2.2 mm screw

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

    • Use the point of a spudger to disconnect the battery connector by prying it straight up from the logic board.

  16. iPhone 6s Battery Replacement: étape 16, image 1 de 2 iPhone 6s Battery Replacement: étape 16, image 2 de 2
    • Push the battery connector away from the logic board until it stays separated from its socket, so as to avoid any accidental connection to the battery while you work.

  17. iPhone 6s Battery Replacement, Unfasten the display cable bracket: étape 17, image 1 de 1
    • Remove the following four Phillips screws securing the display cable bracket:

    • Three 1.2 mm screws

    • One 2.8 mm screw

  18. iPhone 6s Battery Replacement: étape 18, image 1 de 2 iPhone 6s Battery Replacement: étape 18, image 2 de 2
    • Remove the display cable bracket.

  19. iPhone 6s Battery Replacement: étape 19, image 1 de 2 iPhone 6s Battery Replacement: étape 19, image 2 de 2
    • Use a spudger or a clean fingernail to disconnect the front camera flex cable by prying it straight up from its socket on the logic board.

  20. iPhone 6s Battery Replacement: étape 20, image 1 de 2 iPhone 6s Battery Replacement: étape 20, image 2 de 2
    • Disconnect the digitizer cable by prying it straight up from its socket on the logic board.

    • When reconnecting the digitizer cable, do not press the center of the connector. Press one end of the connector, then press the opposite end. Pressing in the center of the connector can bend the component and cause digitizer damage.

  21. iPhone 6s Battery Replacement: étape 21, image 1 de 2 iPhone 6s Battery Replacement: étape 21, image 2 de 2
    • Make sure the battery is disconnected before you disconnect or reconnect the cable in this step.

    • Disconnect the display cable by prying it straight up from its socket on the logic board.

    • Use tweezers to peel back the tips of the two adhesive strips along the bottom edge of the battery.

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

    • Optionally, you may wish to remove the Taptic Engine at this time. It's very easy to remove and will allow better access to the adhesive strips.

  24. iPhone 6s Battery Replacement: étape 24, image 1 de 2 iPhone 6s Battery Replacement: étape 24, image 2 de 2
    • Try to keep the strips flat and unwrinkled during this procedure; wrinkled strips will stick together and break instead of pulling out cleanly.

    • Slowly pull one battery adhesive tab away from the battery, toward the bottom of the iPhone.

    • To avoid tearing the adhesive strip, be careful not to snag it against the battery or lower components.

    • Pull steadily, maintaining constant tension on the strip until it slips out from between the battery and the rear case. For best results, pull the strip at a 60º angle or less.

    • The strip will stretch to many times its original length. Continue pulling and re-grab the strip near the battery if necessary.

  25. iPhone 6s Battery Replacement: étape 25, image 1 de 1
    • Repeat for the second strip.

    • Hold down the battery as you remove the second strip, or the strip may fling the battery when it separates from the case.

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

    • If either of the adhesive strips broke off underneath the battery and could not be retrieved, continue with the next step below.

  26. iPhone 6s Battery Replacement: étape 26, image 1 de 2 iPhone 6s Battery Replacement: étape 26, image 2 de 2
    • If you successfully removed both adhesive strips, move on to the next step. Otherwise, you will need to pry the battery from the rear case.

    • Prepare an iOpener and apply it to the back of the rear case, directly over the battery. Alternatively, you can apply heat using a heat gun or hair dryer.

    • After about a minute, flip the phone over and use a plastic card to break up any remaining adhesive behind the battery.

    • Do not insert your card in the area between the volume down (-) button and the top edge of the battery, or you may damage the volume control cable lying underneath.

    • Do not pry against the logic board or you may damage the phone.

    • Keep the card as flat as possible to avoid bending the battery, which may damage it and cause it to release dangerous chemicals or catch fire. Do not use any sharp tools to pry at 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 behind the upper battery corners, bring the ends together, wrap them around a folded cloth, and pull evenly.

  27. iPhone 6s Battery Replacement: étape 27, image 1 de 1
    • Remove the battery.

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

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

    • Perform a forced restart after reassembly. This can prevent several issues and simplify troubleshooting.

Conclusion

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

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

Easy fix. I would recommend getting the adhesive for the screen, as I completely destroyed about half of it when I removed the screen.

cziebell937 - Réponse

the adhesive strip under the battery do not use your hand to pull out, use tweezer and a stick roll it up slowly.......

luke foxy - Réponse

That's a good idea! But on the other hand it looks a bit funny expanding it to about 1 meter ;-) - especially nice, if the owner is there watching …

Michael Gasperl -

That was actually way better than the original suggestion. If you hold the tweezer a little to the side while you roll up the adhesive, it will come off a little bit easier.

KatSeiko -

I found that instead of trying to pull the adhesive strips straight out, that by shifting the strip side to side as I pulled allowed it to “inch out” and break the bond more on a diagonal and snap out in one piece….
