Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.

Apply a suction handle to the bottom edge of the back glass.

Pull up on the handle with a strong, steady force to create a gap between the back glass and the frame.

Insert the tip of an opening pick into the gap.

As you slice the adhesive securing the back glass in the next steps, be careful of the following areas:

There's a delicate cable connecting the back glass to the phone, right next to the volume up button. Don't insert your pick here to avoid slicing the cable.

There are multiple spring contacts around the perimeter of the phone. Be extra careful not to insert your pick deeper than suggested in each step to avoid bending these contacts.

Don't insert your opening pick deeper than ***5 mm*** along the bottom edge.

Slide your pick back and forth along the bottom edge to separate the adhesive.

Leave this pick inserted to prevent the adhesive from resealing.

Heat the left edge of the back glass until it's hot to the touch.

Don't insert your pick deeper than ***5 mm*** along the left edge.

Leave this pick in place to prevent the adhesive from resealing.

Heat the top right corner of the back glass until it's hot to the touch.

Don't insert your pick deeper than ***4 mm*** along the right edge.

Rotate the second opening pick around the top right corner and slide it to the volume up button to separate the adhesive.

Gently swing open the back glass to the right of the phone.

If the back glass feels stuck, go back around the perimeter to check for missed sections of adhesive or stuck clips.

Use [product|IF145-020|tweezers] to slide the cover toward the top of the phone to unlatch it from the logic board.

Remove the cover.

During reassembly, latch the top edge of the cover onto its slot on the logic board before securing it with its screw.

Hold the back glass upright with one hand and rotate the bottom edge to the left to reveal the [link|https://guide-images.cdn.ifixit.com/igi/JTgBIs4pnklXuCQn.huge|battery press connector|new_window=true] just below the volume buttons.

Use the tip of an opening pick to pry up and disconnect the battery press connector from the logic board.

A plus and minus sign is printed on the head of this connector.

To reconnect a [guide|25629|press connector|stepid=70308|new_window=true], align it over its socket and gently press down on one side until it clicks into place, then press down on the other side. Make sure it sits flat, as the insulating rubber around the sockets might prevent it from connecting fully.

Use your tri-point Y000 driver to remove the 0.9 mm-long screw securing the middle connector cover.

Use the flat end of a spudger or your finger to push the cover toward the bottom of the phone and unclip its top edge.

Remove the cover.

During reassembly, place the cover so its tab is just behind the [link|https://guide-images.cdn.ifixit.com/igi/J1ZxsIErWymM2OwF.huge|clip on the logic board|new_window=true]. Press down with one finger and slide the cover forward to engage the clip.

Slide an opening pick under the battery cable to separate it from the logic board.

Be careful not to crease the cable or dent the battery with your tool.

Your iPhone's battery is secured with two [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, and avoid using sharp tools near it.

Use the tip of an opening pick to scrape up an edge of each stretch release pull tab from the top of the battery until you can grip the tab with blunt nose [product|IF145-020|tweezers].

Use blunt nose tweezers to grip a pull tab and peel it from the battery.

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

Repeat for the other pull tab.

The stretch release adhesive wraps around the top edge of the battery, and must be separated before you remove the strips.

Hold one of the pull tabs away from the battery with tweezers.

Use an opening pick to slice the adhesive securing the strip to the top edge of the battery.

Repeat for the other pull tab.

Use your blunt nose tweezers to grip the entire length of an adhesive strip's pull tab.

Twist your tweezers to roll the adhesive strip over itself and pull it slowly, evenly, and at a low angle out from under the battery.

Give the strip plenty of time to stretch. Avoid dragging it over cables or components as you pull.

If you're using your fingers, re-grip the strip often to avoid it stretching unevenly and tearing.

Repeat for the other strip.

If a strip breaks off, try to retrieve it from under the battery. If you can't retrieve it, don't worry! Move on to the next step for an alternate method.

Use a pipette or syringe to apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to the inside edge of the battery.

Prop up the top edge of the phone and repeat this for the upper edge of the battery.

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

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

Insert the long edge of a [product|IF145-101|plastic card] between the left edge of the battery and the frame.

Hold the phone steady and pry the battery up.

Depending on how strong your adhesive is, this may take some time. Allow up to a minute of constant pressure for the adhesive to loosen.

Slide the plastic card deeper under the battery until you can pry it up.

Lift the battery until you can grab it with your fingers.

Remove the battery.

To install a new battery:

Clean your frame with isopropyl alcohol and a lint-free or microfiber cloth.

***Before applying adhesive***, temporarily reconnect your new battery and place it in its recess to check if it fits and that the cable reaches the socket on the logic board. Disconnect the battery before continuing.
