Your iPhone 13 no longer charges properly? It discharges way too fast?

In this detailed photo tutorial, we will show you step by step how you can easily replace the battery yourself.

If your battery is inflated, keep in mind that the gas inside the battery is flammable and can escape. If you do not feel confident enough, have it replaced at a repair shop.

To avoid scratches on the case, make sure your workspace is clean and level.

We wish you good luck with your repair!

20 steps
  1. Switching off your iPhone12

    iPhone 13 - Switching off your iPhone12 02
    iPhone 13 - Switching off your iPhone12 03

    Before repairing, we recommend that you use our checklist to test the basic functions of your iPhone 13. This way you can check afterwards if your repair was successful.

    1. Press and hold the side and volume down key simultaneously for a few seconds.
    2. Wipe the displayed slider from left to right.
  2. Unscrewing the screen

    • 2 × 6.8 mm Pentalobe

    Once you open your iPhone its specified IP68 certification will expire.

    We recommend using a screw storage to keep all disassembled parts and screws safe and organized. Our magnetic pad has the additional advantage that nothing can move on it.

    1. Unscrew the two Pentalobe screws left and right of the Lightning connector.
    2. Then put them into a screw storage.
  3. Heating up the edge of the screen

    Used tools
    Heat gun

    The screen of the iPhone 13 is heavily glued. In order to remove it, you first have to heat the adhesive sufficiently with hot air. For this, use a hot air device, such as a hot air dryer or an ordinary hair dryer.

    1. Run a hot air device evenly over the edge of the screen.
    Used tools
  4. Lifting up the screen

    We recommend a flat pick to insert between the screen and the case unit. Alternatively, the iPlastix and iFlex can be helpful as well.

    1. Attach a suction cup to the lower edge of the screen and pull it firmly upwards to create a narrow gap between the screen and the case unit.
    2. Insert a flat, stable tool into the gap to enlarge it.

    Used tools

    Do not insert your tool too far on the side of the volume buttons to avoid damaging any cables inside the device.
    Be careful not to open the screen too far while the sensitive screen cables are still attached.

    1. Move the plastic tool once around the edge of the screen. Press it upwards at the same time to release its hooked lugs from the case unit.
    2. When the screen is completely detached, you can carefully unfold it towards the volume buttons. Lean it against a stable object.

  6. Removing the cover plates

    • 4 × 1.2 mm Phillips
    • 1 × 1.7 mm Y-Type
    • 1 × 1.6 mm Phillips

    To remove the screen completely, you have to detach the battery connector as well as the two screen connectors. These are located under two cover plates.

    The upper cover plate is hooked on one side.

    1. Unscrew the six screws from the two cover plates and put them in your screw storage.
    2. Then carefully remove the plates from your device with a pair of tweezers.

    Since the tabs of the four adhesive strips are attached very flatly, you should be careful not to accidentally damage the battery.

    1. Use tweezers to carefully detach the black tabs from the battery.
    2. Slowly pull the adhesive strips out from under the battery with tweezers. Pull them out as flat as possible, so that they do not tear.

    2. Remove the carrier film of the adhesive frame and press it onto the edge of the case.

  18. Testing the new battery

    Before you close your iPhone 13 for good, we recommend testing the replacement battery as well as other basic functions of your phone. This way, you can make sure that your repair was successful. Again, use our checklist for this.

    In order for the new battery to be recognized after the replacement, you have to connect your device to the power supply to switch it on initially.

    1. Carefully fold the screen around, but do not press it into the case yet.
    2. Connect a charging cable to see if the new battery charges.
    3. If something does not work properly, check again if everything is installed and attached correctly.

    • 4 × 1.2 mm Phillips
    • 1 × 1.7 mm Y-Type

    Be careful not to mix up the screw lengths. A too long screw in the wrong place may damage the device.

    The upper cover plate is additionally hooked on one side.

    1. Position the two cover plates over the connectors. The screw holes help you with the alignment.
    2. Screw the cover plates in place. Fix them with tweezers, so that they do not move.

    2. Flip the screen around and press it firmly into the case frame, so that it sits level all over. You should hear and feel it click into place.
