iPhone 15 Plus Battery Disconnection

Step 1

Allow your phone's battery to drain below 25%, as a charged lithium-ion battery is a potential safety hazard.
Unplug any cables from your phone.
Hold the power and either volume buttons and slide to power off your phone.

Step 2

If your screen or back glass is badly cracked, lay overlapping strips of packing tape over the glass to protect yourself and make disassembly easier.
Make sure there's a smooth area near the bottom edge that's big enough for a suction cup to stick to.

Step 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.

Got to step 2 and realized the fix kit doesn't include an opening pick! Looks like a guitar pick, and I have those lying around. Is that expected? Looks like the pick is used in many steps below. There's a little blue crowbar that isn't mentioned in the instructions. Perhaps that replaces the opening pick?

Hi! I can't see which guide you were using when writing this comment. Can you reply here with which guide and fix kit you used?

I see you posted this in Meta. I hope it's resolved soon! In the meantime, a guitar pick may work well enough for your repair.

what fix kit?

Meow Purr -

My fix kit didn't include an opening pick either

WILLIAM HARRIS -

Make sure you check inside the black boxes after emptying them. My pick was stuck inside one of the boxes.

My AliExpress refurbished screen came with a pick that has a coin-like circle that pops out, so no modification was necessary

Step 4

Use a P2 pentalobe driver to remove the two 7.7 mm-long screws on either side of the charging port.

Step 5

The next four 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 four steps for an alternate method.
For complete instructions on how to use the Anti-Clamp, check out this guide.
The Anti-Clamp applies suction to both the screen and the back glass. To open only the back glass, you need to secure the screen with tape. You can also check out the full instructions on how to use this tape.
Cut two strips of tape, apply them along the long edges of the phone, and fold them over the screen to secure it.

Step 6

Pull the Anti-Clamp's blue handle backward to unlock the arms.
With the back glass facing up, slide the arms over the right edge of your phone, with one suction cup on the back glass and the other on the screen. Center the suction cups near the bottom edge.
Support your phone so it rests level while between the Anti-Clamp's arms—a small box works well.
Squeeze the cups together to create suction.
If you find that the surface of your phone is too slippery for the Anti-Clamp to hold onto, use tape to create a grippier surface.

Step 7

Pull the blue handle forward to lock the arms.
Turn the handle one full turn (360 degrees) or until the cups start to stretch.
As the cups stretch, make sure they stay vertically aligned with each other. If they keep slipping, remove the Anti-Clamp and apply tape for the cups to stick to.
If you don't have tape, you may warm up the suction cups to help them stick.

Step 8

Use a hair dryer or heat gun to heat the bottom edge of the back glass until it's hot to the touch.
Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.
Wait up to a minute for the adhesive to separate and a gap to form between the back glass and the frame.
If a gap doesn't appear after one minute, apply more heat and rotate the handle a quarter turn. Let the Anti-Clamp and time do the work for you.
Insert an opening pick into the gap.
Remove the Anti-Clamp using the pull tabs on the suction cups.
Skip the next two steps.

Step 9

Use a hair dryer or heat gun to heat the bottom edge of the back glass until it's hot to the touch.
Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.

Step 10

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.

Step 11

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.

Step 12

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 your pick inserted in the bottom right corner to prevent the adhesive from re-sealing.

Step 13

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

Step 14

Don't insert your pick deeper than 7 mm along the right edge.
Rotate your pick around the bottom right corner and slide it halfway up the right edge or until you feel a hard stop at a clip securing the back glass.
Don't slice near the volume buttons to avoid damaging the wireless charging cable.
Leave this pick inserted to prevent the adhesive from resealing.

Step 15

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

Step 16

Don't insert your pick deeper than 5 mm along the left edge.
Insert a second opening pick at the bottom edge.
Rotate the second pick around the bottom left corner.
Slide this pick up to the top left corner to separate the adhesive.
Leave this pick inserted to prevent the adhesive from resealing.

Step 17

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

Step 18

Don't insert your pick deeper than 3 mm along the top edge.
Rotate your second opening pick around the top left corner and slide it to the top right corner to separate the adhesive.
You might hear and feel clicks as the top two clips release.
Leave this pick in place to prevent the adhesive from resealing.

Step 19

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

Step 20

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.

Step 21

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.
Rest the back glass against a raised surface so it doesn't strain the cable.

Step 22

Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.
Use a tri-point Y000 driver to remove the two 1.3 mm-long screws securing the lower connector cover.

Step 23

Use 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.

Step 24

Hold the back glass upright with one hand and rotate the bottom edge to the left to reveal the battery press connector 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 press connector, 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.
