Xiaomi Redmi Note 11 Pro Battery Replacement

What you need

  1. Xiaomi Redmi Note 11 Pro Battery Replacement, Heat the rear glass: step 1, image 1 of 1
    • Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen the adhesive underneath.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

    • Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.

    • If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.

    • If you're having trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap you created.

    • Slide the opening pick to the bottom right corner to slice the adhesive.

    • Leave the opening pick in place to prevent the adhesive from resealing.

    • If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener for one to two minutes to reheat it.

    • Insert a third opening pick at the bottom left corner of your phone.

    • Slide the opening pick along the left edge of your phone to slice the adhesive.

    • Leave the opening pick in the top left corner to prevent the adhesive from resealing.

    • Insert a fifth opening pick underneath the top right corner.

    • Slide the opening pick along the right edge of the rear glass to slice the remaining adhesive.

    • At this point, the rear glass should be separated from the frame. If there's still resistance around the edges of the glass, use an opening pick to separate any remaining adhesive.

    • Remove the rear glass.

    • Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

    • Secure the new back cover with pre-cut adhesive or double-sided adhesive tape. After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

    • Press directly into the hole to eject the SIM card tray.

    • Remove the SIM card tray.

    • Peel the battery off the remaining adhesive.

    • Remove the battery.

    • Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard.

    • Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

    • During reassembly, temporarily reconnect the battery to the motherboard to help align it correctly. Disconnect the battery after it is seated.

Conclusion

If possible, turn on your device and test your repair before installing new adhesive and resealing.
