iPhone 13 mini Battery Replacement Tutorial (Step-by-Step)

• Use a Pentalobe screwdriver to remove the two 6.7 mm pentalobe screws located at the bottom edge of the iPhone, next to the charging port.
  

• Apply a heat gun or hairdryer to the bottom edge of the iPhone for about 1 to 2 minutes to soften the waterproof adhesive underneath.

1. Apply your suction cup to the lower half of the screen, just above the bottom edge. Pull up on the suction cup with firm, constant pressure to create a slight gap between the front screen glass and the rear housing frame.

2. Immediately insert an opening pick into the gap.

3. Cut the Adhesive:

• Slide the opening pick back and forth along the bottom edge of the iPhone from left to right to slice through the adhesive.
• Leave the pick inserted on one side of the bottom edge to prevent the adhesive from resealing.
• Leave the pick inserted on one side of the bottom edge to prevent the adhesive from resealing.

· Caution: Do not insert your pick more than 3 mm deep, or you risk damaging the fragile ribbon cables located near the edges.

1. Once all adhesive around the perimeter is cut, gently swing the display open from the right side to the left (like opening a book, where the spine is on the left).

• Do not fully separate the screen yet, as it is still firmly connected to the logic board by delicate ribbons.

2. Prop the screen up at about a 90-degree angle against a sturdy object (like a box or a stack of books) to keep it stable.

1. Locate the metal cover bracket in the lower-middle section of the logic board that protects the screen and battery connectors.

2. Use a screwdriver to remove the screw securing this bracket.

3. Use a pair of tweezers to carefully lift the metal bracket out of the phone and set it aside.

Tip: Keep these screws strictly organized (a magnetic mat is recommended). They are different lengths, and putting a long screw into the wrong hole can cause permanent logic board damage

4. Use screwdrivers to remove the screws securing the front sensor assembly bracket near the top of the phone. 

5. Remove the metal bracket.

1. Use the pointed tip of a plastic spudger to gently pry the battery connector up and out of its socket on the logic board.

2. Use your spudger to gently pry up and disconnect the display/digitizer cable connectors.

3. Pry up and disconnect the front sensor assembly cable connector (which houses the flood illuminator, ambient light sensor, and microphone).

Now that the screen is free from any cable connections, remove the display assembly completely and place it on a clean, scratch-free surface.

1. Use a screwdriver to remove the 4 screws securing the lower speaker.

2. Carefully remove the speaker from the phone by hand. (Do not use metal tweezers to avoid puncturing the battery).

The iPhone 13 mini battery is held in place by three stretch-release adhesive strips

1. Use tweezers or your fingers to carefully peel up the black plastic pull tabs from the edges of the battery.

2. The "Slow Pull":

• Grab one of the pull tabs and pull it away from the battery at a very low, flat angle (keep it as close to the flat bottom of the phone as possible).
• The strip will stretch to several times its original length. Maintain slow, steady, and even tension. Do not yank or pull sharply.
  
  
• What to do if a strip snaps: Drop a few drops of high-concentration isopropyl alcohol into the gap between the battery and the rear case. Let it sit for 1–2 minutes to dissolve the adhesive, then use a plastic spudger to gently pry the battery up. Never use metal tools or sharp objects to pry the battery, as puncturing it can cause a fire or explosion.

3. Lift out the Battery: Once the adhesive strips are removed, lift the old battery out of the phone case.
