iPhone 14 Battery Replacement

• Power off your iPhone before beginning disassembly.
• Remove the two 6.8 mm-long pentalobe P2 screws at the bottom edge of the iPhone.

• 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.

• If your iPhone has a cracked rear glass, 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 rear glass 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 rear glass with that instead.
• If all else fails, you can superglue the suction cup to the rear glass.

• Use a hair dryer or a heat gun to heat the bottom edge of the iPhone until the rear glass is slightly too hot to touch.
  Never leave your heat gun in one spot for an extended period of time.

• Apply a suction handle to the bottom edge of the rear glass, while avoiding the very edge of the glass.
• Pull up on the suction cup with firm, constant pressure to create a slight gap between the rear glass and the case.
• Insert an opening pick into the gap.
• The adhesive holding the rear glass 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 rear glass up and down to weaken the adhesive until you create enough of a gap to insert your opening pick.

Heat the left edge of the iPhone until the rear glass is slightly too hot to touch.

• Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the rear glass in place.
• Do not insert your pick more than 3 mm, as you may damage internal components.

There's a delicate cable along the right edge, next to the volume up button. Do not insert your pick here, as you may damage the cable.

Heat the right edge of the iPhone (the edge with the volume buttons) until the rear glass is slightly too hot to touch.

• Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.
• Do not insert your pick more than 3 mm, as you may damage the charging coil cable.

Heat the top edge of the iPhone until the rear glass is slightly too hot to touch.

Insert your pick underneath the top right edge of the phone. Slide it around the top-right corner and halfway across the top edge.

• Insert your pick underneath the top-left edge of the phone. Slide it around the top-left corner and halfway across the top edge.
• Don't insert the pick more than 3 mm, as you may damage or smear the camera array.
• Don't try to fully separate the rear glass yet, as a fragile ribbon cable still connects it to the iPhone's logic board.

• Remove your suction handle from the rear glass.
• Slowly open your iPhone by swinging the rear glass up from the left side, like the back cover of a book.
• Be careful not to strain the short charging coil flex cable.
• Lean the rear glass against something to keep it propped up while you're working on the phone. If you don't have anything at hand to lean the rear glass against, your suction handle can do the trick.

• Use a Y000 screwdriver to remove the two 1.3 mm-long screws securing the battery connector cover.
• Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.
• 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.

• Grasp the battery connector cover with a pair of tweezers and slide it upwards (towards the A15 print) to unlatch the top hook.
• Remove the battery connector cover.

• Use the pointed end of a spudger to disconnect the battery cable by prying the connector straight up from its socket.
• 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 making contact with the socket and providing power to the phone during your repair.

• Use a Y000 screwdriver to remove the single 1.0 mm-long screw securing the charging coil connector cover.

• Use a pair of tweezers to remove the charging coil connector cover.

• Use the pointed end of a spudger to disconnect the charging coil cable by prying the connector straight up from its socket.

• Remove the rear glass assembly.
• Apply new adhesive where necessary after cleaning relevant areas with isopropyl alcohol (>90%).
• During reassembly, pause here if you wish to replace rear glass adhesives.

• Two stretch adhesive strips secure the battery to the case. They're both accessed from the top edge of the battery.
• Each adhesive strip has a black pull-tab at the end, which is lightly adhered to the edge of the battery.
• In the following steps, you'll pull each tab to slowly stretch out the adhesive underneath the battery. These 'command-strip' style adhesives lose their stick when stretched, so you can remove the battery with ease.
• If the strips break, don't panic! They don't always work as intended. Keep reading for tips on removing broken strips.

• Caution: Don't jab the battery with any sharp tools. A punctured battery may leak dangerous chemicals or catch fire.
• Use a pair of blunt-nosed tweezers to peel up the two battery adhesive pull-tabs along the top edge of the battery.

• Grab the first pull-tab with your fingers or wrap it around a spudger and slowly pull it away from the battery, toward the top of the iPhone.
• Pull out hard enough to maintain tension on the strip, but don't force it. Give it plenty of time to stretch and un-stick from under the battery.
• Don't press down on the battery but hold the iPhone firmly by its sides.
• Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.
• If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling-but do not pry under the battery.
• If any of the adhesive strips break off underneath the battery and can't be retrieved, try to remove the other strip, and then proceed as instructed below.

• Grab the second pull-tab with your fingers or the center of a spudger and pull it away from the battery, toward the top of the iPhone.
• Follow the same procedure as with the previous strip: don't press down on the battery, keep the strip flat and unwrinkled, and pull at a low angle.
• If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling-but do not pry under the battery.
• If the adhesive breaks off underneath the battery and can't be retrieved, continue with the next step.

• If you're still having trouble removing the battery, apply a few drops of high concentration (90% or higher) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).
• Wait about one minute for the alcohol solution to weaken the adhesive.
• Use an opening pick or the flat end of a spudger to gently lift the battery.
• Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

• Remove the battery.
• Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard.
• If there's any alcohol solution remaining in the phone, carefully wipe it off before installing your new battery.
• If your new battery didn't come with adhesive preinstalled, refer to this guide for help replacing the adhesive strips.
• Perform a force restart after reassembly. This can prevent several issues and simplify troubleshooting.
