Xiaomi Redmi Note 8 Pro Battery Replacement

Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen the adhesive underneath.

• Use a hair dryer, heat gun, or hot plate as an alternative method, but be cautious not to overheat the phone.

The display and internal battery are susceptible to heat damage.

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

If the rear glass is cracked, the suction handle may not stick; use strong tape or superglue it in place and allow it to cure before proceeding.

• Lift the rear glass with the suction handle to create a small gap between the glass and frame.
• In case of trouble creating a gap, apply more heat using an iOpener (following instructions carefully 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.

Insert a second opening pick near the bottom edge of your phone.

• Slide this new pick towards the bottom left corner to break the adhesive.
• Leave both opening picks in place to prevent re-adhesion.

Reheat the adhesive with your iOpener if it becomes hard to cut.

• Insert a third opening pick at the bottom left corner of your phone.
• Slide this opening pick along the left edge to slice the adhesive.
• Leave this opening pick in place, keeping it at the top left corner to prevent resealing.

• Insert a pick at the top left corner.
• Slide the pick down the top edge to cut the adhesive.
• Leave the pick in place, near the top right corner.

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.

• Do not remove the rear glass all the way yet, as the camera cover and fingerprint assembly is still attached

  .

Be careful when handling the camera cover and rear glass — risk of damage.

• Lift the rear glass upwards while pressing down on the camera cover with your finger.
• The camera cover and fingerprint assembly should separate from the rear glass during this step.

If adhesive is too strong, apply a heated iOpener to the camera cover for 1-2 minutes to loosen it.

• Remove the rear glass completely.

Clean areas around the phone with isopropyl alcohol (>90%) and apply new adhesive as needed.

• Secure the new rear glass using pre-cut adhesive or double-sided tape.
• Apply strong, steady pressure to your phone for several minutes to help adhesive form a good bond.

Use a stack of heavy books or apply consistent pressure to ensure proper bonding.

Prying the connector cover may damage it.

• Insert the pointed end of a spudger into the gap next to the fingerprint connector cover.
• Tilt the spudger downwards and use it to pry up the fingerprint connector cover, applying sufficient force as needed.

Remove the fingerprint connector cover using a pair of tweezers.

• Pull the cover out of its routing, towards the power and volume buttons.

Disconnect the fingerprint reader cable using a spudger. Pry the connector straight up from its socket.

Remove the motherboard cover by unscrewing the ten 3.9 mm Phillips head screws.

Insert the opening pick under the black foil over the battery and interconnect cable.

• Carefully pry the black foil away from the battery and interconnect cable using the opening pick.

• Position the opening pick at the bottom right corner of the motherboard cover.
• Slide the opening pick along the right edge to release the plastic clips, then carefully pry the cover up.

• Insert the opening pick at the top edge of the motherboard cover.
• Pry the motherboard cover up with the opening pick.
• Remove the motherboard cover.

Use a spudger to pry the battery connector straight up from its socket.

Use a spudger to carefully pry the interconnect cable's connector straight up from its socket.

Slide an opening pick under the black foil near the battery and loudspeaker assembly.

Gently pry up to loosen the adhesive, but avoid damaging the components underneath.

• Remove the black protective foil.

Do not fold the interconnect flex cable sharply, as this can cause damage.

• Fold the interconnect flex cable towards the charging port to access both battery pull tabs.
• Use a small piece of tape to secure the cable temporarily if necessary.

Do not pierce the battery with sharp tools — risk of leakage and fire.

• Use tweezers or a clean fingernail to pull down both battery adhesive pull-tabs.
• The tabs should be released from the bottom edge of the battery.

Pull the first pull-tab slowly towards the bottom edge of your phone.

• Maintain tension on the strip by pulling hard enough, but do not force it.
• Give the adhesive time to stretch and un-stick from under the battery.

Do not press down on the battery.

• Hold your phone firmly by its sides.
• Pull at a low angle to avoid snagging the strip on the edge of the battery.
• If the adhesive breaks off, try to retrieve it using your fingers or blunt tweezers and continue pulling.

Do not pry under the battery if the adhesive breaks off underneath.

Repeat the previous pull-tab removal procedure on the second pull-tab.

• Follow the same procedure as before: keep the strip flat and unwrinkled, and pull at a low angle to avoid damaging the battery.

If adhesive breaks off underneath the battery, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery.

• Wait one minute for the alcohol solution to weaken the adhesive.
• Use the flat end of a spudger to gently lift the battery, being careful not to deform or puncture it.

Do not attempt to forcefully lever the battery out. If necessary, apply additional drops of alcohol to further weaken the adhesive.

Remove the battery.

Do not reinstall a damaged or deformed battery, as this poses a potential safety hazard.

• If any alcohol solution remains, wipe it off or allow it to air dry before installing the new battery.
• Temporarily reconnect the battery during reassembly to aid alignment. Disconnect after seating.
