How to fix iPhone 15 Battery Replace

Comprehensive Phone Repair and Inspection Guide

iPhone 15 Battery batteries are rated to hold 80% of their capacity for up to 600 charge cycles, or roughly 20- 26 months. If your iPhone needs to be charged more often or runs slower, it might be time to replace the battery.

Initial Inspection and Assessment

1. Frame and Structural Integrity:
   • Identify a reference alignment line and inspect the middle frame for any damage, skewing, or deformation.
   • Examine all four corners of the device for signs of drop dents or impact damage.
2. Screen and Display Inspection:
   • Check the screen for outward cracks to prevent further damage during cover removal.
   • Inspect for bright spots, vertical lines, or irregular brightness levels.
3. Charging Port and Screws:
   • Assess the charging port for deformation.
   • Ensure that all screws are intact and not stripped.
4. Back Cover and Camera Lens:
   • Inspect the back cover and lens cap for cracks, scratches, or excessive wear.

Functionality Tests

1. Charging Test:
   • Plug in the charging cable and confirm that the device charges normally.
2. Touchscreen Test:
   • Press and hold an icon, then drag it across the entire screen to ensure continuous touch functionality.
   • Any disruptions indicate a touchscreen issue.
3. Audio and Call Functionality:
   • Play music to confirm the proper functioning of the speakers.
   • Make a test call to check if it connects normally.
   • Cover the proximity sensor to verify if the screen turns off during a call.
4. Vibration and Silent Mode:
   • Activate the vibration function to confirm it works correctly.
   • Toggle the silent key while the screen is on and check for response.
5. Light Sensor and Auto Brightness:
   • Ensure the automatic brightness feature functions correctly.
   • Verify that the light sensor responds as expected.

Disassembly Process

1. Preparing for Disassembly:
   • Power off the iPhone 15 Battery to prevent unnecessary damage.
   • Use a pentalobe screwdriver to remove the two screws at the bottom of the device.
2. Removing the Back Cover:
   • Place a suction cup at the lower left corner of the back cover.
   • Insert a triangular disassembly tool into the gap and slide it left and right to separate the back cover.
   • Lift the back cover no more than 100°.
3. Battery and Component Disassembly:
   • Use a triangular screwdriver to remove screws securing the battery ribbon connector bracket.
   • Disconnect and remove the battery ribbon connector.
   • Carefully disconnect the screen module cable terminals to avoid component damage.
   • Use a triangle opening tool to lift the battery adhesive tab.
   • Wrap the adhesive tabs around tweezers and peel them away to remove the battery.

Battery Inspection and Replacement

1. New Battery Inspection:
   • Ensure the outer packaging of the new battery is intact, with no visible damage or leakage.
   • Confirm the iPhone 15 Battery connector is in good condition.
2. Installing the New Battery:
   • Remove the protective film from the battery adhesive.
   • Position the battery correctly and connect the ribbon connector.

   • Remove the blue film protective layer.
2. Securing the Back Cover:
   • Reconnect the back cover cable terminal to the mainboard.
   • Fix the iron sheet in place with screws using a triangular screwdriver.
   • Insert the top of the screen diagonally into the back cover.
   • Gently press along the edges to ensure the back cover is properly installed.
   • Use a pentalobe screwdriver to reinstall the bottom screws.

Final Functionality Tests
