Your iPhone's battery is secured with three [link|https://www.ifixit.com/News/45779/ask-ifixit-what-is-stretch-release-adhesive-and-why-do-we-love-it|stretch release adhesive strips|new_window=true]. The next four steps show how to remove them and free your battery.

Be careful not to dent or puncture the battery. Avoid using sharp tools near it.

Use the tip of an opening pick to separate a black pull tab from the bottom of the battery.

Use tweezers to help peel the tab away from the battery.

Don't try to pull the tab out from under the battery just yet.

Use tweezers or your fingers to grab the pull tab.

Slowly pull the adhesive out from under the battery at as low of an angle as possible.

Give the strip plenty of time to stretch and re-grip it as necessary. Avoid dragging it over the components or cables above the battery.

When the strip becomes too long, wrap it around your tweezers and continue pulling.

If a strip breaks off, try to retrieve it from under the battery. If you can't retrieve it, move onto the next strip.

Repeat the procedure with the two remaining adhesive strips.

Carefully bend the lower assembly cable out of the way as needed to access the adhesive strips.

If you removed all three stretch release adhesive strips, congratulations! Remove the battery and ***skip down three steps*** for reassembly instructions.

If one or more adhesive strips broke, ***skip to the next step*** to remove them with isopropyl alcohol.

The next two steps show how to remove the battery if the adhesive strips broke.

Lift the bottom edge of the frame to tilt the iPhone.

Use a pipette or a syringe to apply 2–3 drops of high concentration (>90%) isopropyl alcohol along the bottom edge of the battery, close to where each broken adhesive strip came out.

Wait one minute for the isopropyl alcohol to flow under the battery and soften the adhesive.

Insert the flat edge of an opening pick between the left edge of the battery and the frame.

Pry the battery upwards slowly with steady force. Give the adhesive time to release.

Don't bend or crease the battery. If it feels stubborn, apply a few more drops of isopropyl alcohol and try again.

Once the adhesive loosens, grab and remove the battery.

Congratulations on completing disassembly! ***The remaining steps will show how to reassemble your iPhone.***

Depending on your iPhone model, some reassembly photos may have minor visual discrepancies. The procedure, however, will be correct for your iPhone.

Remove any remaining adhesive from the battery recess. Wipe the frame surface with a lint-free cloth and a few drops of isopropyl alcohol.

Peel the adhesive liner away from the battery.

If your new battery doesn't have adhesive installed, [guide|137171|follow this guide|new_window=true] to apply new [product|IF145-458|stretch release adhesive strips|new_window=true], or use [product|IF317-072-2|thin, double-sided tape|new_window=true] to secure it.

The battery adhesive is very sticky! Be careful as you align the battery in its recess—once it sticks, you won't be able to realign it.

Lower the battery partially into its recess.

Temporarily connect the battery to the logic board to ensure that the cable reaches.

Lay the battery in its recess.

Use your fingers to press firmly against the battery for ten seconds to bond it to the frame.

***Disconnect the battery from the logic board.***

Angle the bottom edge of the loudspeaker towards the frame.

Press the loudspeaker into its recess.

Install the four screws securing the loudspeaker:

One 1.7 mm‑long Phillips screw

One 1.5 mm‑long Phillips screw

One 4.1 mm‑long standoff screw

One 1.3 mm‑long tri-point Y000 screw

Lay the Taptic Engine in its recess.

Use your finger to pivot the corner bracket down into place.

Use a Phillips screwdriver to install the 2.1 mm‑long screw securing the Taptic Engine.

Use your finger to gently press the lower assembly cable onto the top of the Taptic Engine.

Install the two screws securing the lower assembly cable:

One 1.0 mm‑long tri-point Y000 screw

One 1.3 mm‑long Phillips screw

Use your finger or a spudger to press and connect the two lower assembly cable connectors.

Lay the Taptic Engine cover in place and align it by its screw holes.

Make sure the bottom edge of the cover latches properly to the frame.

Use a Phillips screwdriver to install the three screws securing the Taptic Engine cover:

One 2.9 mm‑long screw

One 1.3 mm‑long screw

One 2.4 mm‑long screw

Use your finger or a spudger to press the assembly cable connector onto the logic board.

Work around the fragile grounding clips as you're cleaning the frame. If you bend one out of place, gently bend it back with your fingers or tweezers.

Use [product|IF145-020-4|blunt nose tweezers] or your fingers to remove large pieces of adhesive from the frame perimeter.

Use a spudger to scrape the adhesive residue off of the frame.

If the adhesive feels stubborn, apply some heat using a [guide|157348|hair dryer|new_window=true] or [guide|151116|heat gun|new_window=true] and try again.

If you're reusing your back glass, apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to a [product|IF145-284|microfiber] or lint-free cloth and wipe around the perimeter to prepare the surface for new adhesive.

Wrap a lint-free cloth or a coffee filter over the point of a spudger and apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to it.

Wipe in one direction along the perimeter of the frame to clean the adhesive residue.

Take your time doing this. A clean frame allows replacement adhesive to lay evenly, ensuring a better bond.

Lay the adhesive sheet over the frame to determine its proper orientation.

Use features such as the camera cutout and notches along the top and bottom edges to visualize how the adhesive will lay in the frame.

Grab the tab in the corner of the adhesive sheet and peel the liner to expose ***a third ***of the adhesive.

The exposed adhesive is very sticky. Don't let it touch anything until you're ready to apply it to the frame.

If your adhesive has multiple liners, peel the liner that exposes the side that sticks to the frame.

Carefully align the exposed edge of the adhesive strip with the corresponding edge of the iPhone's frame.

Once the adhesive is pressed into place, you can't reposition it—you'll have to remove it and start over with new adhesive.

When it's correctly aligned, gently press the exposed adhesive strip onto the frame.

Continue peeling away the liner from the adhesive, gently pressing the adhesive into place.

If you've correctly aligned the adhesive, the edges will fall perfectly into place.

If your adhesive is slightly misaligned, gently pull the long edges into alignment with the frame.

If the adhesive begins to crease or wrinkle, remove it and start over with fresh adhesive.

If you don't have another set of adhesive strips handy, it's okay to temporarily put your iPhone back together and use it normally without any adhesive. Just keep in mind that your iPhone's water resistance will be compromised until you replace the adhesive.

Use a spudger to press the adhesive around the entire perimeter of your iPhone.

Work around the fragile grounding clips. If you bend one out of place, gently bend it back with your fingers or tweezers.

Don't press too hard, or you'll stretch and deform the adhesive.

Use a spudger or your fingers to lift the pull tab connected to the large front liner. The pull tab is often in a corner of the liner.

Use the pull tab to peel off the large front liner from the adhesive.

At this point, you may still have liner covering the perimeter, which prevents the adhesive from accidentally sticking to anything while you're reassembling your iPhone. ***Don't remove these small release liners just yet.***

Prop up the back glass along the right edge of your iPhone.

Use your finger or the flat end of a spudger to press and connect the back glass connector onto the logic board.

Use your finger or a spudger to press and connect the battery press connector onto the logic board.

***This is a good point to test your repair before sealing up your iPhone. ***Power on your iPhone and make sure it works as expected. Power it back down and continue reassembly.

If your iPhone doesn't turn on, connect it to a power source and try again.

If you've replaced the logic board and the screen fails to turn on, you'll need to follow the [guide|178634|screen guide|new_window=true] to manually connect the display connector.

Align the back glass connector cover by its screw holes and lay it in place.

Use a tri-point Y000 driver to install the four screws securing the back glass connector cover:

Two 1.3 mm‑long screws

Two 1.0 mm‑long screws

Align the battery connector cover by its screw holes and lay it in place.

Use a tri-point Y000 driver to install the three screws securing the battery connector cover:

Two 1.3 mm‑long screws

One 1.0 mm‑long screw

Use your fingers or a spudger to peel away all perimeter liners, exposing the adhesive.

As you remove the liners, make sure nothing touches the exposed adhesive.

Check the frame and back glass for any stray liners and remove them. There should be no liners remaining.

Lower the back glass onto the frame, beginning with the top edge.

If you feel resistance, a perimeter clip may have bent out of place and is being crushed by the frame. Look at the point of resistance and gently straighten any bent clips.

Press along the edges of the iPhone until the back glass sits flush against the frame.

Use a [guide|157348|hair dryer|new_window=true], [guide|151116|heat gun|new_window=true], or an [guide|25705|iOpener|new_window=true] to heat the back glass perimeter until it's slightly too hot to touch.

The heat softens the adhesive and helps create a better bond.

Use your fingers to firmly squeeze around the perimeter of the iPhone.

Place your iPhone screen-side down on a clean, flat work surface.

Lay a strip of tape around the perimeter of the back glass to protect the finish.

Stack coins around the perimeter of the back glass until you create a wall that's as tall as the rear camera protrusions.

Alternatively, you can use [guide|142291|vise clamps] around the perimeter of your device to set the new adhesive.

Place 3-4 heavy books squarely on top of your iPhone.

The coins may leave a slight impression on the bottom book cover, so don't use anything valuable.

Leave the books in place for about 30 minutes.

The pressure will help activate the adhesive.

Use a P2 pentalobe driver to install the two 7.4 mm-long screws on either side of the charge port.
