Introduction
iPhone batteries degrade with use—over time, they lose their ability to hold a full charge. Apple's batteries are rated to hold 80% of their capacity for up to 500 charge cycles, which lasts roughly 18-24 months for most users. When your battery's chemistry is degraded, it may also cause your iPhone to run more slowly. Use this guide to replace your battery and restore your iPhone to full performance.
If your battery is swollen, take appropriate precautions.
Note: After the repair, your iPhone may display a warning about the “genuineness” of the battery, even when using original Apple parts. If your iPhone functions normally, you can safely ignore the warning.
The “battery health” section will not show up after a battery replacement. Apple disables this functionality when you replace the battery yourself.
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%.
Tools
Parts
-
-
Power off your iPhone before beginning disassembly.
-
Remove the two 6.7 mm-long pentalobe screws at the bottom edge of the iPhone.
-
-
-
Lay overlapping strips of clear packing tape over the iPhone's screen until the whole face is covered.
-
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.
-
-
-
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.
-
-
-
Pull the blue handle forward 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.
-
-
-
Heat an iOpener and thread it through the arms of the Anti-Clamp.
-
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 under the screen and the plastic bezel, not the screen itself.
-
Skip the next three steps.
-
-
-
Use a hairdryer or heat gun, or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.
-
-
-
If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the curved portion of the glass.
-
-
-
Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
-
Insert an opening pick under the screen and the plastic bezel, not the screen itself.
-
-
-
Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the display in place.
-
-
-
Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.
-
-
-
Slide the opening pick around the top corner of the display, while gently pulling or wiggling the display down in the direction of the Lightning port.
-
Slide the pick to the opposite corner and cut any remaining adhesive securing the display.
-
-
-
Open the iPhone by swinging the display up from the left side, like the back cover of a book.
-
Lean the display against something to keep it propped up while you're working on the phone.
-
-
-
Remove three 1.2 mm Y000 screws securing the battery connector cover bracket.
-
Remove the bracket.
-
-
-
Use the point of a spudger to pry the battery connector straight up out of its socket.
-
Bend the connector 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.
-
-
-
Remove the two 1.2 mm Y000 screws securing the display connector bracket.
-
Remove the bracket.
-
-
-
Remove the five screws securing the logic board connector bracket to the rear case:
-
One 1.3 mm Phillips #000 screw
-
One 1.5 mm Phillips #000 screw
-
Three 1.2 mm Y000 screws
-
Remove the bracket.
-
-
-
Remove the seven screws securing the bracket below the Taptic engine and speaker:
-
Three Phillips 1.4 mm screws
-
Two Phillips 1.7 mm screws
-
One Phillips 1.9 mm screw
-
One Phillips 1.6 mm screw
-
-
-
Lift the bracket from the edge nearest the battery. Don't try to fully remove it, as it's still connected via a small flex cable.
-
-
-
While holding the bracket out of the way, use the point of a spudger to pry up and disconnect the flex cable underneath.
-
-
-
Remove the piece of black tape and the small rubber rectangle covering the Taptic Engine connector cover.
-
-
-
Remove the five screws securing the lower speaker:
-
One 2.8 mm standoff screw
-
One 2.3 mm standoff screw
-
One 2.3 mm Phillips screw
-
One 1.8 mm Phillips screw
-
One 1.6 mm Phillips screw
-
-
-
Remove the small bracket on the top right corner of the speaker.
-
Remove the Taptic Engine connector cover.
-
-
-
Insert a spudger under the top edge of the speaker near the edge of the iPhone's case.
-
Gently pry up and lift the top edge of the speaker.
-
-
-
Hold the speaker by its side edges and rock it side-to-side, separating the adhesive securing it to the bottom edge of the iPhone.
-
Pull the speaker away from the bottom edge of the iPhone until the adhesive gasket separates.
-
-
-
Use a spudger to disconnect the Taptic Engine flex cable by prying it straight up from its socket.
-
-
-
Each piece of adhesive has a black pull-tab at the end, which is lightly adhered to the side edge of the battery.
-
-
-
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.
-
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.
-
-
-
Repeat the above steps to remove the remaining three adhesive strips.
-
If you removed all of the adhesive strips successfully, skip the next step.
-
Wait about one minute for the alcohol solution to weaken the adhesive. Use the flat end of a spudger to gently lift the battery.
-
-
-
If any of the adhesive strips broke off and 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.
-
Flip the iPhone back over and 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. This can take some time since the adhesive is slow to deform, but with patience it will come free. Do not deform or damage the battery.
-
-
-
Remove the battery from the iPhone.
-
Adhere the battery, disconnect it, and continue reassembling your device.
-
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.

Hello and Good morning please I wanted to know if iPhone 8 battery can be fixed in iPhone XR?
Not sure what you’re asking; if your asking if the iPhone 8 battery will fit in an Xr, or vise-versa, the answer is no.
After battery replacement, battery health is disabled. Will a factory reset reenable the battery health?
Hi Jon,
Unfortunately, Apple disables battery health for non-Apple battery repairs. I’ll make sure to add this into the guide intro.
One of my gaskets was as shown in your second photo, the other had been worked into the threads (as if smeared) probably from the factory and was completely unusable.
In place of replacements (unsure of where to purchase) I just used a clear silicone caulking on both screws upon reassembly to offer at least some water seal. I wish these gaskets were included with the gasket waterproofing sealant kit!

Is there any place to buy these screw gaskets? I haven’t seen it mentioned anywhere but one of mine was pretty much chewed up. Silicone should work but I’d prefer the oem solution.
Chilinh Nguyen -
I found a place on Amazon that sells them. It's cheapest to get a full set of screws than to get just these. $5-$6 USD.
J Olin -
Can it be dead?
Lulu navarro -
If I transfer the data from the old to the new battery with an icopy, don't I get an error message?
David Julian Krause -
how am i supposed to know if the battery is below 25% if the screen won't turn on?
Beth Jackson -
Spoiler alert! I just followed all the steps and if you bought the anti-clamp you might save a lot of time and some unreversible steps.
I recommend that you read all the steps before beginning and follow the steps up to the point where the guide removes the screen (step 23). After that read again the precautions of step 41 and try the next thing:
- Using something like the iOpener hot bag, heat up the back side of the phone where the battery is glued to for some minutes
- Alternatively use a 3d printer heat bed at 60 degrees Celsius
- Once the back of the phone is hot to the touch, enough to make it uncomfortable to the touch, find a portion of the battery with a smooth surface and attach the anti-clamp to it and the back of the phone
- Follow the steps 4 and 5 to detach the battery from the frame
If this procedure works you will not have to remove some elements such as:
- lower speaker black tape (step 28)
- lower speaker water proof gasket (step 33)
I hope that someone find this helpful. Happy fixing!!
