Introduction

If your battery is swollen, take appropriate precautions.

For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

You’ll need replacement adhesive to reattach components when reassembling the device.

What you need

Step 1

              Eject the SIM card tray
  • Insert a SIM card eject tool, a SIM eject bit, or a straightened paper clip into the hole on the SIM tray located at the left edge of the phone.
  • Press directly into the hole to eject the SIM card tray.
  • Remove the SIM card tray.

Step 2

              Heat the rear glass
  • 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.

Step 3

              Secure a suction handle
  • 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.
  • The surface of the rear glass is not completely smooth. For a better grip of the suction handle, apply tape to the rear glass or moisten the suction handle.
  • Secure a suction handle to the right edge of the rear glass, as close to the edge as possible.

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

Step 4

              Create a gap
  • Lift the rear glass with the suction handle to create a small gap between the rear glass and the frame.
  • In case you have 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.

  • Insert a third opening pick at the bottom right corner of your phone.
  • Slide the opening pick along the bottom edge of your phone to slice the adhesive.
  • Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.

Step 10

              Remove the rear glass
  • Remove the rear glass.
  • Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
  • Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, 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.

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

For optimal performance, calibrate your newly installed battery after completing this guide.

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.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow these instructions in reverse order. During reassembly apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

Take your e-waste to an R2 or e-Stewards certified recycler.

I noticed that both in your tutorial and in my device, the original battery compatible with the Redmi Note 10 Pro is the Model BN53. However, when I search for replacement batteries, the BN53 is not compatible with the cell phone, and they indicate the BN59. Could you tell me why?
