iPhone 11 Battery Replacement

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 6.7 mm-long pentalobe 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.

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, [link|https://guide-images.cdn.ifixit.com/igi/pQGATIGUbViSB4gB.full|tape a coin to a pick|new_window=true] 3 mm from the tip.

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.

The next three steps demonstrate the [product|IF145-513|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, [guide|152309|check out this guide|new_window=true].

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 top, and one on the bottom.

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 [guide|159595|use tape|new_window=true] to create a grippier surface.

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.

You can also use a [guide|157348|hair dryer|new_window=true], [guide|151116|heat gun|new_window=true], 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 under the screen and the plastic bezel, ***not the screen itself.***

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.***

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

Use a hairdryer or heat gun or [https://www.ifixit.com/Guide/iOpener+Heating/25705|prepare an iOpener|new_window=true] and apply it to the lower edge of the iPhone for about a minute.

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 into the gap under the [link|https://guide-images.cdn.ifixit.com/igi/wIr4Mt4kTQPHBIOX.full|screen and the plastic bezel|new_window=true], ***not the screen itself.***

The watertight adhesive holding the display 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.

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.

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

There are delicate cables along the right edge of your iPhone. ***Don't insert your pick here***, as you may damage the cables.

Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.

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

The top edge of the display is secured with both glue and clips.

Gently pull the right edge of the display '''''down''''' slightly (in the direction of the Lightning port).

Insert your pick into the top-right corner of the phone.

Continue pulling the display down (toward the Lightning port) as needed in order to make a gap large enough for the pick.

Slide the pick to the top left corner and cut any remaining adhesive securing the display.

Don't insert your pick more than 3 mm, as you may damage the Face ID sensor array.

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

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.

Prop the display up against something sturdy.

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.

To access the screws in the following step, tilt the display by slightly lifting its lower edge.

Be careful not to strain or tear the display cables.

Use a Y000 driver to remove the three 1.1 mm-long screws securing the battery connector bracket.

Throughout this repair, [https://www.ifixit.com/Store/Tools/Magnetic-Project-Mat/IF145-167-4|keep track of each screw|new_window=true] and make sure it goes back exactly where it came from.

During reassembly, this is a good point to power on your iPhone and test all functions before you seal the display in place. Be sure to power your iPhone back down completely before you continue working.

Remove the bracket.

Use a spudger or a clean fingernail to pry the battery connector up from its socket on the logic board.

Try not to damage the black silicone seal surrounding this and other board connections. These seals provide extra protection against water and dust intrusion.

Bend the connector slightly away from the logic board to prevent it from accidentally contacting the socket.

Use a Y000 driver to remove the five 1.1 mm screws securing the logic board cover bracket.

Remove the bracket.

Use a spudger or a fingernail to disconnect the LCD panel cable connector.

Disconnect the digitizer connector next to it.

Use the point of a spudger or a fingernail to disconnect the front panel sensor assembly connector.

Remove the display assembly.

During reassembly, pause here if you wish to [https://www.ifixit.com/Guide/iPhone+Display+Adhesive+Replacement/93983|replace the waterproof adhesive around the edges of the display|new_window=true].

Using a Phillips driver, remove the five screws securing the bracket below the Taptic engine and speaker:

Four 1.6 mm screws

One 1.3 mm screw

Remove the lower bracket.

Use [product|IF145-020|tweezers] to lift and remove the black tape and rubber pad covering the Taptic Engine connector.

Use a little heat from a hair dryer or iOpener to make the tape easier to peel up and re-adhere later.

Remove the five screws securing the speaker and brackets:

One 1.9 mm Phillips screw

One 2.3 mm Phillips screw

One 3.1 mm standoff screw

Two 1.6 mm Phillips screws

Remove the small grounding clip on the top right corner of the speaker.

Remove the Taptic Engine connector cover.

Lift and push aside the small board covering the remaining speaker screw in the bottom right corner of the iPhone.

Remove the 2.4 mm standoff screw underneath.

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.

Remove the speaker.

Optionally, to help protect against water and dust intrusion, replace the speaker's adhesive gasket during reassembly:

Peel away any remaining adhesive with tweezers.

Prep the area underneath by cleaning it with a bit of isopropyl alcohol and a lint-free cloth or coffee filter so that the gasket adheres properly.

Install a new gasket onto the speaker, and then install the speaker.

Use a Phillips driver to remove the two 1.8 mm screws securing the Taptic Engine.

Use a spudger to disconnect the Taptic Engine flex cable by prying it straight up from its socket.

Remove the Taptic Engine.

Six pieces of stretch-release adhesive hold the battery in place—three near the top edge, and three near the bottom.

Each piece of adhesive has a black pull-tab at one end, which is lightly adhered and folded onto the top of the battery.

Peel back the three battery adhesive pull tabs from the bottom edge of the battery.

Be careful not to jab the battery with any sharp tools—a punctured battery may leak dangerous chemicals or catch fire.

In the following steps, you'll pull each tab to ''slowly'' stretch out the adhesive underneath the battery. The adhesive releases as it stretches.

If the strips break, don't panic! Keep reading for some additional steps for removing broken strips.

To increase your odds of success:

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

Keep the strips flat and unwrinkled as you pull.

Pull very slowly, giving the strip time to stretch and separate. It takes around 30 seconds of stretching to remove each strip.

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

If a strip does break off underneath the battery and cannot be retrieved, move on to the other strips and then continue with the additional steps below.

***''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.

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 [product|IF145-020|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 other strips, and then proceed as instructed below.

Repeat the above steps to remove the other two adhesive strips near the bottom edge of the iPhone.

Peel back the three battery adhesive tabs from the top edge of the battery.

Don't touch the [https://d3nevzfk7ii3be.cloudfront.net/igi/KeeVElW2nqNBkQEx.full|Face ID sensor modules|new_window=true] near the top of the iPhone.

Pull the top adhesive strips out one at a time, using the same method you've used to pull the bottom 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'''.

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.

The battery should come free with minimal force. If not, add a little more isopropyl alcohol and try again. Do not bend or puncture the battery.

If your battery is stuck and an appropriate liquid solvent is not available, [guide|11677|prepare an iOpener] or use a hair dryer to heat the rear case directly behind the battery.

Heat the iPhone until the rear case is slightly too hot to comfortably touch, but no more.

Flip the iPhone back over and thread a strong piece of string (such as dental floss) underneath the battery.

Wear gloves to protect your fingers, or wrap each end of the string around a tool.

Pull the string from side to side in a sawing motion 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.***

Start from the top or bottom edge of the battery, and pull toward the middle. Don't pull the string through the middle third of the battery, or you may damage the ribbon cables or the wireless charging coil directly underneath.

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.

Remove the battery.

Reinstall the Taptic Engine and speaker before installing a new battery. This helps keep the battery aligned correctly during installation.

Before you adhere the replacement battery, temporarily reconnect the battery connector to the motherboard 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 [https://www.ifixit.com/Guide/iPhone+8+and+8+Plus+Battery+Adhesive+Strips+Replacement/103936|this guide|new_window=true] to replace the adhesive strips.

Perform a [https://www.ifixit.com/Guide/How+to+Force+Restart+an+iPhone+11/126067|force restart|new_window=true] after reassembly. This can prevent several issues and simplify troubleshooting.
