Introduction

Is your battery getting weak? Power up your OnePlus 6! Each step has detailed photos to guide you through this battery replacement. The battery isn't glued in very strong and you don't need tools to remove it.

We advice you to check your spare part before installation. If you find any visible errors, please contact your vendor before starting.

The repair is somewhat more difficult because the OnePlus 6 has to be opened via the glass back cover.

Run a data backup before the repair, use a clean work surface and take enough time. If you have questions, use the live chat on our website or write a comment.

11 steps
  1. Switch off the device

    OnePlus 6 - Switch off the device 01
    OnePlus 6 - Switch off the device 02

    Turn off your OnePlus 6 completely.

    1. Press and hold the standby button until the "Turn off" option is displayed.
    2. Confirm the power off with a second tap.
  2. Remove the back cover

    To loosen the back cover, use a heat gun or an ordinary hair dryer. Warm glue is easier to loosen, allowing you to remove the back cover. The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex.

    You will also need several plastic picks to unstick the back cover all around.

    1. Heat the spot where you start.
    2. Press a flat tool between the back cover and the frame.

    The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert.You can use a suction cup to help lift the rear glass slightly.

    Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.

    1. Once the tool is inserted, stick a pick into the gap to keep it open.
    2. Then run the tool around the entire edge to gradually loosen the glue.
    3. Heat the next part and insert the picks one by one.
    4. Once the back cover is loosened, lift it very slightly. The fingerprint sensor underneath the camera is still connected with a cable.

    If your backcover is broken as well as in this case, you can try to leave it intact and not damage it further. You could use it again after replacing the display, as long as the cracks don't bother you.

  3. Disconnect the fingerprint sensor

    1. Now carefully lift up the loosened back cover and fold it over.
    2. Loosen the adhesive strip over the cover plate.
    3. Remove the cover over the connector with tweezers or your fingers.
    4. Then carefully disconnect the connector with a spudger or your fingernail and remove the back cover.
  4. Disconnect the battery

    2. Disconnect the battery to avoid short circuits during the repair.

    1. Unstick the two transparent adhesive tabs on both sides of the battery.
    2. Now pull the green tab until the battery comes out. Pull carefully so the tab won't tear.

    Be careful not to bend the battery. The battery is not very firmly glued, but if the adhesive is too strong, you can heat the unit from the display side.

  6. Prepare the battery

    OnePlus 6 - Prepare the battery 01

    Transfer the green pull tab to your new battery so you can easily remove it later.

  7. Insert the battery

    1. Place the battery in its place and make sure that it has some space on all sides and is not pressed against the frame or other components.
    2. The battery contact should be directly above its socket on the mainboard.
  8. Connect the battery

    OnePlus 6 - Connect the battery 01

    • Connector

    2. Position the fingerprint sensor cable over its mainboard contact and connect it.
    3. Put on the cover with the red rubber piece. Reattach the black glue.
  10. Test the device

    Before you finally close the device again, you should test it.

    1. Turn on the device and check the screen first.
    2. Slide an app along the edge and zigzag it across the display to make sure the touchscreen responds correctly at all points.
    3. Also test the minimum and maximum brightness.
    4. Test the front and rear cameras and the flash.
    5. Call someone to test the microphone and earcup.
    6. Mute the phone to test the vibration motor.
  11. Attach the back cover

    OnePlus 6 - Attach the back cover 01

    You can reuse the glue still on the frame and back cover. Make sure that it is spread as evenly as possible and remove any glue that has wrinkled or protrudes.

    1. Heat the device again to soften the glue of the back cover.
    2. Press the back cover firmly onto the frame of the device.

    Clamp the device between a few books for example and give the glue an hour to set.
