  1. iPhone 8 Battery Replacement, Remove the pentalobe screws: шаг 1, изображение 1 из 1
    • Before you begin, discharge your iPhone 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 3.5 mm pentalobe screws on the bottom edge of the iPhone.

    • Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

  2. iPhone 8 Battery Replacement, Mark your opening picks: шаг 2, изображение 1 из 3 iPhone 8 Battery Replacement, Mark your opening picks: шаг 2, изображение 2 из 3 iPhone 8 Battery Replacement, Mark your opening picks: шаг 2, изображение 3 из 3
    • If inserted too far, an opening pick can damage your device. Follow this step to mark your pick and prevent damage.

    • Measure 3 mm from the tip and mark the opening pick with a permanent marker.

    • You can also mark the other corners of the pick with different measurements.

    • Alternatively, tape a coin to a pick 3 mm from the tip.

    • The next three steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down three steps for an alternate method.

    • For complete instructions on how to use the Anti-Clamp, check out this guide.

    • Pull the blue handle backwards to unlock the Anti-Clamp's arms.

    • Slide the arms over either the left or right edge of your iPhone.

    • Position the suction cups near the bottom edge of the iPhone just above the home button—one on the front, and one on the back.

    • Squeeze the cups together to apply suction to the desired area.

    • If you find that the surface of your iPhone is too slippery for the Anti-Clamp to hold onto, you can use tape to create a grippier surface.

  4. iPhone 8 Battery Replacement: шаг 4, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 4, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 4, изображение 3 из 3
    • Pull the blue handle forwards to lock the arms.

    • Turn the handle clockwise 360 degrees or until the cups start to stretch.

    • Make sure the suction cups remain aligned with each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.

  5. iPhone 8 Battery Replacement: шаг 5, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 5, изображение 2 из 2
    • Heat an iOpener and thread it through the arms of the Anti-Clamp.

    • You can also use a hair dryer, heat gun, or hot plate—but extreme heat can damage the display and/or internal battery, so proceed with care.

    • Fold the iOpener so it lays on the bottom edge of the iPhone.

    • Wait one minute to give the adhesive a chance to release and present an opening gap.

    • Insert an opening pick into the gap.

    • If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle a quarter turn.

    • Don't crank more than a quarter turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.

    • Skip the next three steps.

  6. iPhone 8 Battery Replacement, Heat the display: шаг 6, изображение 1 из 1
    • The next three steps show how to separate the screen using a suction cup.

    • Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or prepare an iOpener and apply it to the lower edge of the phone for about 90 seconds in order to soften up the adhesive underneath.

  7. iPhone 8 Battery Replacement, Separate the display: шаг 7, изображение 1 из 2 iPhone 8 Battery Replacement, Separate the display: шаг 7, изображение 2 из 2
    • Apply a suction cup to the lower half of the front panel, just above the home button.

    • Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.

  8. iPhone 8 Battery Replacement: шаг 8, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 8, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 8, изображение 3 из 3
    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the frame.

    • Insert an opening pick into the gap.

    • The watertight adhesive holding the screen in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

  9. iPhone 8 Battery Replacement: шаг 9, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 9, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 9, изображение 3 из 3
    • Slide the opening pick up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place.

    • Stop near the top left corner of the display.

    • Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

  10. iPhone 8 Battery Replacement, Screen information: шаг 10, изображение 1 из 1
    • There are delicate cables along the right edge of your iPhone. Don't insert your pick here, as you may damage the cables.

  11. iPhone 8 Battery Replacement: шаг 11, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 11, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 11, изображение 3 из 3
    • Re-insert your tool at the lower right corner of the iPhone, and slide it around the corner and up the right side of the phone to separate the adhesive.

    • Don't insert your pick more than 3 mm, as you may damage the display cables.

  12. iPhone 8 Battery Replacement: шаг 12, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 12, изображение 2 из 2
    • Gently pull up on the suction cup to lift up the bottom edge of the display.

    • Do not raise the display more than 15º or you'll risk straining or tearing the ribbon cables connecting the display.

    • Pull on the small nub on the suction cup to remove it from the front panel.

  13. iPhone 8 Battery Replacement: шаг 13, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 13, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 13, изображение 3 из 3
    • Slide an opening pick underneath the display around the top left corner and along the top edge of the phone to loosen the last of the adhesive.

  14. iPhone 8 Battery Replacement: шаг 14, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 14, изображение 2 из 2
    • Slide the display assembly slightly down (away from the top edge of the phone) to disengage the clips holding it to the rear case.

  15. iPhone 8 Battery Replacement: шаг 15, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 15, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 15, изображение 3 из 3
    • Open the iPhone by swinging the display up from the left side, like the back cover of a book.

    • Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.

    • Lean the display against something to keep it propped up while you're working on the phone.

  16. iPhone 8 Battery Replacement, Disconnect the battery: шаг 16, изображение 1 из 2 iPhone 8 Battery Replacement, Disconnect the battery: шаг 16, изображение 2 из 2

    • Remove four Phillips screws securing the lower display cable bracket to the logic board, of the following lengths:

    • Two 1.3 mm screws

    • Two 2.8 mm screws

    • Throughout this guide, keep careful track of your screws so that each one goes back where it came from during reassembly. Installing a screw in the wrong place can cause permanent damage.

    • Remove the bracket.

  17. iPhone 8 Battery Replacement: шаг 17, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 17, изображение 2 из 2
    • Use the point of a spudger to pry the battery connector out of its socket in the logic board.

    • Bend the battery connector cable slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

  18. iPhone 8 Battery Replacement, Disconnect the display and digitizer: шаг 18, изображение 1 из 2 iPhone 8 Battery Replacement, Disconnect the display and digitizer: шаг 18, изображение 2 из 2
    • Use the point of a spudger to pry the lower display connector out of its socket.

    • To re-attach press connectors like this one, press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

  19. iPhone 8 Battery Replacement: шаг 19, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 19, изображение 2 из 2
    • Use the point of a spudger to disconnect the second lower display cable.

  20. iPhone 8 Battery Replacement: шаг 20, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 20, изображение 2 из 2
    • Remove the three 1.3 mm Phillips screws securing the bracket over the front panel sensor assembly connector.

    • Remove the bracket.

  25. iPhone 8 Battery Replacement: шаг 25, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 25, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 25, изображение 3 из 3
    • Gently slide an opening pick between the antenna flex cable and the top of the speaker.

    • This portion of the flex cable is lightly adhered in place. If necessary, apply a little heat from an iOpener or hair dryer to soften the adhesive. This will make it easier to separate the flex cable safely.

  26. iPhone 8 Battery Replacement: шаг 26, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 26, изображение 2 из 2
    • Use the point of a spudger to pry up and disconnect the diversity antenna flex cable from the logic board.

  27. iPhone 8 Battery Replacement: шаг 27, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 27, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 27, изображение 3 из 3
    • Slide an opening pick under the antenna flex cable to hold the socket down.

    • Use the point of your spudger to pry up and disconnect the antenna flex cable from its socket, using the opening pick to hold the socket down.

    • Reconnecting this cable can be tricky. Make it easier by using your tweezers to hold the flex cable so the connector aligns with its socket. Then, gently press straight down on the connector with the flat of your spudger until it clicks into place.

  28. iPhone 8 Battery Replacement: шаг 28, изображение 1 из 1
    • Remove the Wi-Fi diversity antenna.

    • Remove the two screws securing the Taptic Engine:

    • One 2.1 mm Phillips screw

    • One 2.1 mm standoff screw

    • Standoff screws are best removed using a standoff screwdriver or bit.

    • In a pinch, a small flathead screwdriver will do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.

  30. iPhone 8 Battery Replacement: шаг 30, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 30, изображение 2 из 2
    • Use the point of your spudger to pry the antenna cable socket up and away from the connector below it.

  31. iPhone 8 Battery Replacement: шаг 31, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 31, изображение 2 из 2
    • Use the point of your spudger to pry up and disconnect the Taptic Engine flex cable.

  32. iPhone 8 Battery Replacement: шаг 32, изображение 1 из 1
    • Remove the Taptic Engine.

  33. iPhone 8 Battery Replacement, Remove the battery adhesive: шаг 33, изображение 1 из 1
    • The iPhone's battery is secured by four pieces of stretch-release adhesive—two at the top, and two at the bottom.

    • Each piece of adhesive has a black pull-tab at the end, which is lightly adhered to the front surface of the battery.

  34. iPhone 8 Battery Replacement: шаг 34, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 34, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 34, изображение 3 из 3
    • Peel back the first battery adhesive tab from the bottom right edge of the battery.

    • If possible, use your fingernails or blunt tweezers. Be careful not to poke the battery with any sharp tools.

  35. iPhone 8 Battery Replacement: шаг 35, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 35, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 35, изображение 3 из 3
    • Try to keep the adhesive strips flat and unwrinkled during this procedure; twisted or wrinkled strips will stick together and break instead of pulling out cleanly.

    • Additionally, do not press down on the battery as you pull the strips. Pressing on the battery creates pressure points that can snag and break the adhesive.

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

    • 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 as low an angle as possible, without snagging it on any of the iPhone's other components.

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

    • 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.

  36. iPhone 8 Battery Replacement: шаг 36, изображение 1 из 3 iPhone 8 Battery Replacement: шаг 36, изображение 2 из 3 iPhone 8 Battery Replacement: шаг 36, изображение 3 из 3
    • Repeat the above steps to remove the remaining three adhesive strips.

    • Be sure to hold onto the battery as you remove the final strip, or it may fling out of the iPhone unexpectedly.

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

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

  37. iPhone 8 Battery Replacement: шаг 37, изображение 1 из 2 iPhone 8 Battery Replacement: шаг 37, изображение 2 из 2
    • If any of the adhesive strips broke off and the battery remains stuck to the rear case, remove it by adding a few drops of isopropyl alcohol (90% or greater) underneath the battery near the stuck strip(s). After about a minute, 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.

    • If you choose to use pry tools to lift the battery out of the iPhone, use extreme caution or you may damage the ribbon cables or the wireless charging coil directly underneath 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. This will help soften the adhesive.

    • Heat the iPhone until the rear case is slightly too hot to comfortably touch. Don't overheat the iPhone, or you may accidentally ignite the battery.

    • Alternatively, thread a strong piece of string (such as dental floss or a length of thin guitar string) underneath the battery.

    • Pull the string from side to side in a sawing motion all along the length of the battery to separate the adhesive. Do not deform or damage the battery.

    • To protect your fingers, wear gloves or wrap the string ends around a tool (such as the two screwdriver handles shown in the image).

  38. iPhone 8 Battery Replacement, Remove the battery: шаг 38, изображение 1 из 1
    • Remove the battery from the iPhone.

    • If your replacement battery came in a plastic sleeve, slide off and remove the sleeve before installation.

    • 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.

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

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

    • 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.

Заключение

To reassemble your device, follow these instructions in reverse order. Don't forget to reapply the display adhesive before reinstalling the display.

I still did it in 30 minutes….but I am glad I stop repairing phones around the Iphone 6s ! Now it takes serious effors just to replace the battery !

Wayne Demers - Ответить

One note on this repair: When reinstalling the standoff that connects to the Taptic Engine, I found that the pointy tip of the spudger fits really well into the little hole at the top of the standoff, and helps with getting it into place and screwing it down if you don’t have a screwdriver bit for the standoff. Hope this is helpful!

Are steps 18 to 27 really required if you’re just replacing the battery?

Daniel Frenberg - Ответить

Hi Daniel!

The pull-stretch adhesive holding the battery has a tendency to tear when they are pulled at a steep angle. When they tear, removing the battery becomes much more difficult. We strongly recommend removing the Taptic Engine in order to give the adhesive the best chance of coming out in one piece.

Arthur Shi -

I tried doing it the ‘easy’ way without those steps. I wound up breaking the top adhesive tabs and it made it a lot harder to remove the battery and took a lot of extra time. If I had to do it again, I would do all the steps. Otherwise, things went very well. Very good instructions.
