iPhone 13 Pro Max Battery Replacement

What you need

  1. iPhone 13 Pro Max Battery Replacement, Remove the pentalobe screws: step 1, image 1 of 1
    • Caution: 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 6.8 mm-long pentalobe P2 screws at 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 13 Pro Max Battery Replacement, Mark your opening picks: step 2, image 1 of 3 iPhone 13 Pro Max Battery Replacement, Mark your opening picks: step 2, image 2 of 3 iPhone 13 Pro Max Battery Replacement, Mark your opening picks: step 2, image 3 of 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.

  3. iPhone 13 Pro Max Battery Replacement, Tape over any cracks: step 3, image 1 of 3 iPhone 13 Pro Max Battery Replacement, Tape over any cracks: step 3, image 2 of 3 iPhone 13 Pro Max Battery Replacement, Tape over any cracks: step 3, image 3 of 3
    • If your iPhone has a cracked screen, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.

    • Lay overlapping strips of clear packing tape over the iPhone's screen until the whole face is covered.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

    • If you can't get the suction cup to stick in the next few steps, fold a strong piece of tape (such as duct tape) into a handle and lift the screen with that instead.

    • If all else fails, you can superglue the suction cup to the screen.

  4. iPhone 13 Pro Max Battery Replacement, Anti-Clamp instructions: step 4, image 1 of 3 iPhone 13 Pro Max Battery Replacement, Anti-Clamp instructions: step 4, image 2 of 3 iPhone 13 Pro Max Battery Replacement, Anti-Clamp instructions: step 4, image 3 of 3
    Tool used on this step:

    • 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—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.

  5. iPhone 13 Pro Max Battery Replacement: step 5, image 1 of 3 iPhone 13 Pro Max Battery Replacement: step 5, image 2 of 3 iPhone 13 Pro Max Battery Replacement: step 5, image 3 of 3
    • Push the blue handle away from the hinge to engage opening mode.

    • Turn the handle clockwise until you see 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.

  6. iPhone 13 Pro Max Battery Replacement: step 6, image 1 of 3 iPhone 13 Pro Max Battery Replacement: step 6, image 2 of 3 iPhone 13 Pro Max Battery Replacement: step 6, image 3 of 3
    • Support your iPhone on something sturdy such as a hardcover book so it rests hands-free and parallel to the ground; this makes it easier to work with in the following steps.

    • Use a hair dryer to heat along the bottom edge of the iPhone. The screen should feel slightly too hot to touch.

    • For complete instructions on how to use a hair dryer, check out this guide.

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

    • Insert an opening pick under the screen's plastic bezel when the Anti-Clamp creates a large enough 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.

  7. iPhone 13 Pro Max Battery Replacement, Heat the bottom edge: step 7, image 1 of 1
    • Use a hair dryer or a heat gun to heat the bottom edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

    • Never leave your hair dryer in one spot for an extended period of time.

  8. iPhone 13 Pro Max Battery Replacement, Insert an opening pick: step 8, image 1 of 3 iPhone 13 Pro Max Battery Replacement, Insert an opening pick: step 8, image 2 of 3 iPhone 13 Pro Max Battery Replacement, Insert an opening pick: step 8, image 3 of 3
    • Apply a suction handle to the bottom edge of the phone, while avoiding the very edge of the glass.

    • 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 under the screen's plastic bezel.

    • 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 13 Pro Max Battery Replacement, Heat the right edge: step 9, image 1 of 2 iPhone 13 Pro Max Battery Replacement, Heat the right edge: step 9, image 2 of 2
    • Use a hair dryer to heat the right edge of the iPhone (the edge with the power button) for 90 seconds or until the screen is slightly too hot to touch.

  10. iPhone 13 Pro Max Battery Replacement, Separate the right adhesive: step 10, image 1 of 3 iPhone 13 Pro Max Battery Replacement, Separate the right adhesive: step 10, image 2 of 3 iPhone 13 Pro Max Battery Replacement, Separate the right adhesive: step 10, image 3 of 3
    • Slide the opening pick around the bottom right corner of the iPhone to separate its adhesive.

    • Continue sliding up the right edge of the iPhone until you reach the top right corner.

    • Don't insert your pick more than 3 mm, as you may damage internal components.

    • Leave the pick in the top right corner before continuing.

  11. iPhone 13 Pro Max Battery Replacement, Heat the top edge: step 11, image 1 of 1
    • Use a hair dryer to heat the top edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

  12. iPhone 13 Pro Max Battery Replacement, Separate the top adhesive: step 12, image 1 of 3 iPhone 13 Pro Max Battery Replacement, Separate the top adhesive: step 12, image 2 of 3 iPhone 13 Pro Max Battery Replacement, Separate the top adhesive: step 12, image 3 of 3
    • Slide the opening pick around the top right corner of the iPhone to separate the top adhesive.

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

    • Leave the pick in the top left corner before continuing.

  13. iPhone 13 Pro Max Battery Replacement, Heat the left edge: step 13, image 1 of 2 iPhone 13 Pro Max Battery Replacement, Heat the left edge: step 13, image 2 of 2
    • Use a hair dryer to heat the left edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

  14. iPhone 13 Pro Max Battery Replacement, Screen information: step 14, image 1 of 1
    • There are delicate cables along the left edge of your iPhone. Don't insert your pick here, as you may damage the cables.

  15. iPhone 13 Pro Max Battery Replacement, Separate the left adhesive: step 15, image 1 of 2 iPhone 13 Pro Max Battery Replacement, Separate the left adhesive: step 15, image 2 of 2
    • Insert a second opening pick in the bottom left corner of the iPhone.

    • Twist both picks simultaneously until the left edge clips release.

    • Apply the twisting force gradually.

    • If you're having trouble separating the adhesive, reheat the left edge.

  16. iPhone 13 Pro Max Battery Replacement, Open the iPhone: step 16, image 1 of 3 iPhone 13 Pro Max Battery Replacement, Open the iPhone: step 16, image 2 of 3 iPhone 13 Pro Max Battery Replacement, Open the iPhone: step 16, image 3 of 3
    • Remove your suction handle from the screen.

    • Rotate your iPhone so the right edge faces you.

    • Open your iPhone by swinging the display up from the right side, like the front 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.

    • During reassembly, lay the display in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the display down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the display and make sure they aren't bent.

    • Remove the Taptic Engine.

  31. iPhone 13 Pro Max Battery Replacement, Locate the adhesive pull-tabs: step 31, image 1 of 1
    • The battery is secured to the rear case with four pieces of stretch-release adhesive—two on the bottom edge of the battery, and two on the top edge.

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

    • In the following steps, you'll pull each tab to slowly stretch out the adhesive underneath the battery. These "command-strip" style adhesives lose their stick when stretched, so you can remove the battery with ease.

    • If the strips break, don't panic! They don't always work as intended. Keep reading for tips on removing broken strips.

  32. iPhone 13 Pro Max Battery Replacement, Remove the stretch-release adhesive: step 32, image 1 of 2 iPhone 13 Pro Max Battery Replacement, Remove the stretch-release adhesive: step 32, image 2 of 2
    • Use a pair of blunt-nosed tweezers to peel down the two battery adhesive pull-tabs along the bottom edge of the battery.

    • Caution: Don't jab the battery with any sharp tools. A punctured battery may leak dangerous chemicals or catch fire.

  33. iPhone 13 Pro Max Battery Replacement: step 33, image 1 of 3 iPhone 13 Pro Max Battery Replacement: step 33, image 2 of 3 iPhone 13 Pro Max Battery Replacement: step 33, image 3 of 3
    • Grab the first pull-tab with your fingers or the center of a spudger and slowly pull it away from the battery, toward the bottom of the iPhone.

    • Pull hard enough to maintain tension on the strip, but don't force it. Give it plenty of time to stretch and un-stick from under the battery.

    • Don't press down on the battery. Hold the iPhone firmly by its sides.

    • Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.

    • Pull at a low angle so the strip doesn't snag on the edge of the battery.

    • If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

    • If any of the adhesive strips break off underneath the battery and can't be retrieved, try to remove the other strips, and then proceed as instructed below.

  34. iPhone 13 Pro Max Battery Replacement: step 34, image 1 of 3 iPhone 13 Pro Max Battery Replacement: step 34, image 2 of 3 iPhone 13 Pro Max Battery Replacement: step 34, image 3 of 3
    • Grab the second pull-tab with your fingers or the center of a spudger and pull it away from the battery, toward the bottom of the iPhone.

    • Follow the same procedure as with the previous strip: don't press down on the battery, keep the strip flat and unwrinkled, and pull at a low angle.

    • If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

    • If the adhesive breaks off underneath the battery and can't be retrieved, continue with the next step.

  35. iPhone 13 Pro Max Battery Replacement: step 35, image 1 of 2 iPhone 13 Pro Max Battery Replacement: step 35, image 2 of 2
    • Use a pair of blunt-nosed tweezers and an opening pick to peel up the two remaining battery adhesive pull-tabs from the top edge of the battery.

    • Using the same procedure as before, pull the remaining two tabs, one at a time, to stretch and remove the remaining adhesive strips holding the battery in place. Try not to snag the adhesive on anything.

    • Be careful not to fling the battery from the iPhone as the final adhesive strip comes out.

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

    • Otherwise, continue with the next step below.

    • If you're still having trouble removing the battery, 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 an opening pick or 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.

  38. iPhone 13 Pro Max Battery Replacement, Remove the battery: step 38, image 1 of 1
    • Remove the battery.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off with a coffee filter or lint-free cloth, or allow it to air dry before installing your new battery.

    • If your new battery didn't come with adhesive preinstalled, refer to this guide for help replacing the adhesive strips.

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

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.

No the battery is not okay, the battery is dangerous and needs to be disposed of appropriately and safely

Alaaedin Abdalla -

Does this come with the bms, I know usually to report the battery health data you need to weld the genuine apple bms on the the battery, I am assuming that it has one but just not the apple one hence why it wont track the battery health? is this correct? i would just like to know before purchasing

I replaced the battery and phone wouldn't charge with cable or wireless is this a problem with the battery or something else and has anyone seen this problem before

raja singh - Reply

How Apple could make this SO %#*@ convoluted, and difficult, extensively pulling out near everything else in the phone, BEFORE you can get to take out the battery?!?

This is UNBELIEVABLE.

I cant believe no one has commented this here before me , also!!

PS, did you guys used to give difficulty score ratings on each teardown? now I see a tiny little "moderate" there but...idk. this is pretty heavy repair for anyone if you're not already familiar and have also kept up to date or at least fixed an iPhone 11 or/preferably and, a 12 Pro Max.

Such a drag....

thanks for the teardown and I'm probably going to buy the battery from you guys , but I really thought id be going into this, pop out those pentalobes and be halfway done already! f%&k!
