Battery replacement of iPhone 13

Before starting, it is necessary to discharge the iPhone below 25% because a charged Li-ion battery can ignite or explode if accidentally cut.

• Turn off iPhone.
• Unscrew the two 6.75 mm long pentalob screws on the bottom edge of the iPhone using a Pentalobe screwdriver (Ph0001.2).

Opening iPhone will break its waterproof seal, so have a replacement seal ready before beginning this step.  Without a new seal, your iPhone will not be waterproof.

Warming the bottom edge of iPhone helps soften the screen protector and make it easier to open.

• Using a hair dryer or heat gun, heat the bottom edge of iPhone for about 3 minutes to bring the temperature to about 80 ° C.
• Do not put iPhone in the microwave !!!

• Place the suction cups near the bottom edge of iPhone, one at the front and the other at the back, and gently push it into place.
• Hold your iPhone securely and use gentle suction cups to separate the screen from the back of the phone.
• After separating the display approx. 3 mm from the back, insert the Fixservis card into the gap.

The glue that holds the display in place is very strong, so creating this initial gap requires considerable force.  If you have difficulty, reheat the bottom edge and gently slide the screen up and down repeatedly to weaken the glue until you create a gap to insert the Fixservis card.

• After successfully releasing the adhesive from the edges, remove the suction cups.
• Open iPhone by turning the display to the left like a book.
• We recommend that you support the display so that you do not tear off the flat flex cable that holds the display from the system board.

For now, don't try to completely detach the display, as a few fragile flat cables still connect it to the iPhone's motherboard.

• Remove the two 1.25 mm screws using a Pentalobe screwdriver (Y) securing the connector cover and at the same time remove it with tweezers.

Throughout the repair, follow each screw to make sure it returns exactly where it came from to avoid damaging your iPhone.

• Use the tip of the Spudger to disconnect the battery connector on the system board from the system board.
• Bend the connector slightly away from the system board to prevent accidental contact with the outlet and power to the phone during repair.

• Disconnect the OLED panel and digitizer cable connector using the Spudger.

• Using a Pentalobe screwdriver, remove the two 1.1 mm screws that secure the front sensor connector cover:
• Then remove the cover.

Throughout the repair, follow each screw to make sure it returns exactly where it came from to avoid damaging your iPhone.

• Disconnect the front sensor assembly cable connector using the Spudger or nail.

• Remove the display assembly.

• Four pieces of stretch glue hold the battery in place - two at the top edge and two at the bottom edge.
• Each piece of glue has black gluten at one end, which is easily glued and folded to the top of the battery.
• Using blunt tweezers, grasp the tabs at the same time and slowly pull the adhesive away from the battery.
• Repeat this process from all sides.

• Remove the battery using Spudger.
• When removing the battery, clean the inside of the iPhone with an IPA Plus Cleanser designed to clean electronic contacts.

• Remove the old glue along the edges of the iPhone.

• Peel off the blue plastic sheet from the new set of adhesive tapes and discard.
• Carefully place the adhesive tapes on the battery and stick them in place as shown.
• Use your fingers or a cloth to firmly press the strips into place on the battery.
• Press the center to attach the black control label to the battery as well.

• Carefully insert the battery into the iPhone.
• Make sure the battery connector is in line with the system board.

• Stick new gluten on the edges of the iPhone.

Reconnect the battery.

The new adhesive will ensure the iPhone's resistance to water and dust.

To reinstall, follow these instructions in reverse order.
