Xiaomi Redmi Note 7 Battery Replacement - Xiaomi Redmi Note 7

Step 1 | Loosen the rear glass adhesive

Apply a iOpener to the rear glass and heat it.

Hold the iOpener in place for at least two minutes.

Step 2 | Insert an opening pick

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

For badly cracked rear glass, cover with clear packing tape for improved suction.
Alternatively, use strong tape instead of the suction cup or apply superglue.

Be cautious not to overheat the adhesive while using heat – follow iOpener instructions carefully.

Lift the rear glass with the suction handle to create a small gap between the glass and frame.
If needed, apply more heat to soften the adhesive further.
Insert an opening pick into the gap.
Slide the pick to the bottom right corner to slice the adhesive.

Step 3 | Slice the bottom edge adhesive

Insert a second opening pick at the bottom left corner.
Slide it towards the edge to cut through the adhesive.

Leave the opening picks in place — adhesive may reseal if removed prematurely.

Step 4 | Slice the lefthand-side adhesive

Check if the adhesive has cooled down; use your iOpener to reheat it if needed.

Insert a third opening pick at the bottom left corner.
Slide the opening pick along the left edge of the phone to slice the rear glass adhesive.
Leave the opening pick in place at the top left corner to prevent resealing of the adhesive.

Step 5 | Slice the top edge adhesive

Insert a fourth opening pick under the top left corner of the rear glass.

Slide the opening pick along the top edge of the phone to slice the rear glass adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Step 6 | Slice the righthand-side adhesive

Insert the fifth opening pick in the top-right corner.

Slide the opening pick along the right edge to cut remaining adhesive.
Stop before removing rear glass completely, as fingerprint sensor is still connected.

Step 7 | Open up the phone assembly

Avoid stretching or pinching the fingerprint flex cable when folding the rear glass.

Fold the rear glass to the left side, similar to opening a book cover.

Step 8 | Unfasten the screws

Use a Phillips screwdriver to remove the three 3.3 mm-long screws holding the connector cover in place.

Step 9 | Remove the connector cover

Remove the connector cover with a pair of tweezers.

Step 10 | Disconnect the battery

Insert the flat end of a spudger under the battery flex cable and gently pry it up.

The cable should release from its socket on the motherboard.

Step 11 | Peel the protective foil off

Separate the back cover, including the fingerprint sensor, from the phone assembly for easier handling.

Use a pair of tweezers to carefully peel off the yellow protective foil from the ZIF connector.

Step 12 | Open the ZIF connector

Locate the ZIF connector and use the pointed end of a spudger to lift its black flap.

Step 13 | Disconnect the fingerprint flex cable

Use tweezers to gently pull the fingerprint flex cable directly out of the ZIF connector.

Step 14 | Unfasten the screws

Remove the screws holding the loudspeaker assembly in place using a Phillips screwdriver.

The screws have a length of 3.3 mm.

Ensure the loudspeaker assembly is securely seated before reassembling.

Step 15 | Remove the loudspeaker assembly

Insert an opening pick under the right edge of the loudspeaker assembly.

Use the opening pick to gently pry up the loudspeaker assembly.
Once loose, carefully lift out the loudspeaker assembly.

Step 16 | Disconnect the main flex cable

Use the flat end of a spudger to carefully pry up and disconnect the main flex cable.

Step 17 | Unfasten the screw

Remove the midframe screw with a Phillips screwdriver.

The screw is 3.3mm long.

Step 18 | Remove the display connector cover

Remove the display connector cover using a pair of tweezers.

Step 19 | Disconnect the display flex cable

Use the flat end of a spudger to gently pry up and release the display flex cable.

Step 20 | Remove the main flex cable

Use the flat end of a spudger to carefully pry up and release the main flex cable.

Once disconnected, gently lift the main flex cable away from its connector.

Step 21 | Fold back the display flex cable

Never pierce or deform the battery — potential leakage and overheating hazards.

Fold the display flex cable towards the phone's bottom edge.
Secure it with a small piece of tape to your work surface.

Step 22 | Remove the pull tabs

Avoid applying force that may damage the battery.

Use blunt nose tweezers to peel off the black end of the left pull tab from the battery.
Pull slowly towards the bottom, maintaining tension on the strip without forcing it.
Avoid pressing down on the battery and instead hold the device firmly by its sides.
Maintain a flat and unwrinkled strip while pulling evenly across the whole surface.

Do not pry under the battery if the strip breaks off; instead, retrieve it using your fingers or tweezers and continue to pull gently.

Step 23

Use blunt nose tweezers to gently grasp the black colored end of the right pull tab.

Pull the tab away from the battery, towards the bottom of the device.

Step 24 | Remove the battery

Disconnect and remove the battery.
