How to Replace the iPhone 13 Mini Battery？

Before starting, prepare the following tools and materials:

• Suction cup or screen separator tool

• Pentalobe screwdriver, Y-type screwdriver, Phillips screwdriver

• Plastic prying tools, tweezers

• Battery adhesive strips, insulating tape

• High-capacity replacement battery cell

• Soldering iron with temperature control

• Anti-static gloves

• Airtightness testing machine (optional but recommended)

Step 1: Pre-repair Airtightness Test (00:52)

Before disassembling the device, it's important to perform a pre-repair airtightness test to assess the current water and dust resistance.

This can be done using a specialized pressure-testing device or by checking for leaks through basic pressure difference methods.

Step 2: Disassemble & Remove the Original Battery (03:34)

1. Power off the device completely.

2. Remove the two pentalobe screws near the charging port.

3. Use a suction cup and pry tool to gently lift the screen (be cautious of display cables).

4. Unscrew and remove the bracket covering the battery connector.

5. Disconnect the battery flex cable.

6. Slowly pull the adhesive strips beneath the battery; if needed, soften with isopropyl alcohol.

7. Carefully remove the battery.

Tip: Handle the battery gently — do not puncture it.

Step 3: Solder the High-Capacity Battery Cell (07:35)

Now solder the high-capacity replacement battery cell to the logic board:

1. Align the solder pads and double-check polarity.

2. Carefully solder the positive, negative, and data lines using a precision soldering iron.

3. Inspect the joints and wrap them with insulation for safety.

Step 4: Install Battery & Reassemble the Logic Board (09:56 & 09:18)

1. Attach new adhesive strips and place the replacement battery.

2. Reinstall the logic board in its original position.

3. Reconnect all cables and secure them with brackets.

4. Connect the battery flex cable last.

5. Reattach the screen and tighten all screws.

Step 5: Post-repair Airtightness Test (14:34)

To ensure the iPhone still maintains its water resistance, conduct a post-repair airtightness test.
A successful result confirms proper sealing between the frame and screen.
