OnePlus 7T Battery Replacement - OnePlus 7T

Step 1 | Heat the rear glass

Power off your phone before starting repairs.

Apply a heated iOpener to the rear glass for two minutes to loosen adhesive.
Alternative methods include using a hair dryer, heat gun, or hot plate, but be cautious not to overheat the device — this can cause damage to the AMOLED display and internal battery.

Step 2 | Insert an opening pick

Apply a suction handle to the right edge of the rear glass.

If the back cover is cracked, try lifting it with strong tape or superglue the suction handle in place and allow it to cure.
Pull on the suction handle to create a gap between the rear glass and the frame.
Insert an opening pick into the gap.

Step 3 | Slice the adhesive

Insert an opening pick along the edge to the bottom right corner.

Slide the opening pick to the bottom right corner.
Leave it in place to prevent adhesive resealing.
The suction handle may be removed or retained for better grip.

Step 4

Insert a second opening pick into the gap.
Slide this pick along the edge to the top right corner.

If you encounter difficulties with slicing, reheat the adhesive using the iOpener.

Leave this pick in place at the top right corner to prevent resealing.

Step 5

Avoid damaging or smearing the camera by inserting only the tip (~4-5 mm) of the opening pick when slicing near it.

Insert a third opening pick under the top right corner of the rear glass.
Slide the opening pick along the edge to the top left corner, cutting the adhesive in the process.
Leave the opening pick in place at the top left corner to prevent resealing of the adhesive.

Step 6

Insert a fourth opening pick under the top left corner.

Slide the opening pick along the edge to the bottom left corner, cutting the adhesive.
Leave the opening pick in the bottom left corner to prevent resealing of the adhesive.

Step 7

Insert a fifth opening pick at the bottom left corner.

Slide the pick along the edge to the bottom right corner.
Continue until the remaining adhesive is cut.

Step 8 | Remove the rear glass

Remove the rear glass.

Clean the relevant areas with isopropyl alcohol (>90%) and apply new adhesive as needed.
Secure the new back cover using pre-cut adhesive or double-sided adhesive tape.

Apply strong, steady pressure to your phone for several minutes to ensure a good bond. A stack of heavy books can be used for added pressure.

Step 9 | Unscrew the motherboard cover

Remove the motherboard cover using a Phillips screwdriver.

Locate and remove eleven 3.6 mm screws.

Note: One of these screws is hidden beneath a white water damage sticker.

Step 10 | Remove motherboard cover

Insert the tip of an opening pick into the right bottom corner of the motherboard cover.
Slide the opening pick along the edge of the motherboard cover to release the plastic clips.
Remove the motherboard cover.

Step 11 | Disconnect the battery

Disconnect the battery connector using a spudger, prying it straight up from its socket.

Step 12 | Disconnect the flex cables

Disconnect the two flex cables using the flat end of a spudger.

Step 13 | Reposition the flex cables

Avoid sharply bending the flex cables, which may cause damage.

Bend both flex cables toward the bottom of the phone and out of the way of the battery.

Step 14 | Remove the adhesive tape

Use a spudger to gently pry off the adhesive tape along the left edge of the battery.

Step 15 | Remove the battery

Peel back the red pull tab.

Pull up on the red pull tab to lift the battery out of its recess and swing it up to an upright position.

If you're having trouble removing the battery, apply an iOpener to loosen the adhesive underneath.

Step 16 | Remove the battery

Remove the battery.

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

Secure the new battery with pre-cut adhesive or double-sided adhesive tape, applying it to the device's original adhesive locations.
Press the new battery firmly into place.

Temporarily reconnect the battery to the motherboard during reassembly to aid in alignment. Disconnect after seating.
