Xiaomi Redmi Note 10 5G Battery Replacement

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

Use a hair dryer, heat gun, or hot plate with caution - overheat risk damaging phone display and internal battery.

Secure a suction handle to the bottom edge of the back cover, as close as possible.

If the back cover is cracked, it may not stick; use strong tape or superglue and allow to cure before proceeding.

• Lift the back cover with the suction handle, creating a small gap between the back cover and frame.
• If no gap forms, apply more heat to soften the adhesive further; refer to iOpener instructions for safe use.

Insert an opening pick into the created gap.

Slide the opening pick to the bottom right corner, slicing the adhesive.

Leave the opening pick in place to prevent resealing of the adhesive.

• Insert another opening pick at the phone's bottom edge.
• Guide this new pick towards the bottom left corner to break the adhesive seal.

Leave the picks in place to prevent re-adhesion.

If the adhesive becomes hard to cut, it has likely cooled down.

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

Insert opening pick into top left corner of phone.

• Slide opening pick along top edge to cut adhesive.
• Leave one opening pick in top right corner to prevent resealing.

Insert the fifth opening pick at the top right corner.

• Slide it down the right edge of the back cover to cut through the remaining adhesive.

Remove the back cover.

Clean the area with isopropyl alcohol (at least 90%) before applying new adhesive.

• Apply new adhesive or double-sided adhesive tape to secure the rear glass.
• Place phone under a stack of heavy books and apply strong, steady pressure for several minutes to aid bonding.

Remove the four 3.9 mm Phillips screws securing the camera cover.

Insert an opening pick into the gap between the left edge of the camera cover and the midframe.

• (Using a gentle prying motion) Tilt the camera cover downwards with your opening pick to loosen it.

Remove camera cover.

Use a Phillips screwdriver to remove the thirteen 3.9 mm-long screws securing the midframe.

Insert a SIM eject tool, SIM eject bit, or straightened paper clip into the hole on the SIM tray located at the left edge of the phone.

• Press directly into the hole to avoid damaging the SIM card or tray.

• Remove the SIM card tray.

Disconnect the power and volume button flex cable by gently prying the connector straight up with a spudger.

Locate the SIM tray slot, which is found on the left edge of the phone.

• Insert a thin plastic opening pick carefully into the gap between the midframe and front panel assembly at this location.

Insert an opening pick into the left edge of the phone.

• Work the pick along the edge, applying gentle to moderate pressure to release the plastic clips.

Slide the opening pick along the bottom edge of the phone to release the plastic clips.

Insert an opening pick into the phone's right edge and gently slide it down to disengage the plastic clips.

Slide the opening pick along the top edge of the phone.

• This will release any remaining plastic clips.

The power and volume button flex cable must be freed from any tangles or constraints before removing the midframe.

• Freed the power and volume button flex cable from around the motherboard.
• Remove the midframe.

Disconnect the battery flex cable using a spudger, prying the connector straight up.

• Fold the battery cable to one side for clear access to the battery pull-tab.

Be cautious when handling the battery — risk of puncture and chemical release.

• Use blunt nose tweezers or a clean fingernail to gently pry up both battery adhesive pull-tabs.

Grasp the first pull-tab with a tweezers or your fingers.

• Pull slowly away from the battery towards the top edge of your phone, maintaining tension on the strip.
• Do not press down on the battery; instead, hold the phone firmly by its sides.
• Keep the strip flat and unwrinkled while pulling evenly along the whole length.

If the adhesive breaks off underneath the battery, do not pry under it. Continue with the next step if retrieval is impossible.

Repeat the pull-tab removal procedure for the second tab.

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

If adhesive breaks off underneath the battery and can't be retrieved, apply 2-3 drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery where the broken strip(s) are located.

• Wait about one minute for the alcohol solution to weaken the adhesive.

Gently lift the battery using the flat end of a spudger, without applying force or leverage that could deform or puncture the battery. If needed, apply additional drops of alcohol to further weaken the adhesive.

Never reinstall a damaged or deformed battery — potential safety hazard.

• Remove the old battery.
• Wipe off any remaining alcohol solution or let it air dry before installing your new battery.

Secure the new battery with pre-cut adhesive or double-sided tape, applying it in original positions, not directly onto the battery.

• Press the new battery firmly into place.
• Temporarily reconnect the battery to the motherboard for alignment. Disconnect after seating the battery.
