Einleitung

Use this guide to replace the battery in your OnePlus 9 5G.

For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

It isn't mandatory to remove the daughterboard cover and the interconnect cable in order to replace the battery. However, doing so reduces the risk of damaging surrounding components. If you're experienced in repairs and decide not to do so, deal with the interconnect cable like with the charging port cable in step 25 of this guide.

You'll need replacement adhesive for the battery and the rear glass in order to complete this repair.

Note: Retaining water resistance after the repair depends on how clean the mating surfaces are and how accurately the adhesive is reapplied. Your device will lose its factory-given IP (Ingress Protection) rating, however, only the T-Mobile versions of the OnePlus 9 5G offer an IP rating.

Werkzeuge

Ersatzteile

Schritt 1

Completely power off your phone before you begin.
Prepare an iOpener and apply it to the rear glass for at least three 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.

Schritt 2

Apply a suction handle to the rear glass, as close to the bottom edge as possible.
If your rear glass is badly cracked, covering it with a layer of clear packing tape may allow the suction handle to adhere. Alternatively, very strong tape may be used instead of the suction handle. If all else fails, you can superglue the suction handle to the broken rear glass.
Pull up on the suction handle with strong, steady force to create a gap between the glass and the frame.
If you have trouble creating a gap, apply more heat to further soften the adhesive.
Insert an opening pick into the gap.

Schritt 3

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.

Schritt 4

Insert a second opening pick underneath the bottom edge of the rear glass.
Slide the opening pick to the bottom left corner to slice the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Schritt 5

If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener to reheat it.
Insert a third opening pick underneath the bottom left corner of the rear glass.
Slide the opening pick along the left edge of your phone to slice the adhesive.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Schritt 6

Insert a fourth opening pick underneath the top left corner of the rear glass.
Slide the opening pick along the top edge to slice the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Schritt 7

Insert a fifth and final opening pick underneath the top right corner of the rear glass.
Slide the opening pick along the right edge of the back cover to slice the remaining adhesive.

Schritt 8

Remove the rear glass.
If the back cover is still stuck to the frame, slide an opening pick around the entire perimeter until the rear glass separates completely.
During reassembly secure the 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.

Schritt 9

Use a pair of tweezers to carefully peel the bottom right corner of the charging coil tape off of the daughterboard cover.

Schritt 10

Use a pair of tweezers to carefully peel the bottom left corner of the charging coil tape off of the loudspeaker.

Schritt 11

The flash assembly is held in place by mild adhesive and covers a motherboard cover screw.
Carefully slide an opening pick underneath the bottom edge of the flash assembly.
Use your opening pick to pry up the flash assembly.
Don't try to remove the flash assembly all the way during this procedure. Its cable is adhered to the backside of the motherboard cover.

Schritt 12

Use a Phillips screwdriver to remove the ten 3.8 mm-long screws securing the motherboard cover.
One of the motherboard cover screws is covered by a white water ingress sticker. To unfasten the screw you can puncture the sticker with your screwdriver.

Schritt 13

The motherboard cover is further held in place by tight plastic clips.
Insert a spudger underneath the bottom right edge of the motherboard cover.
Pry upwards to loosen the motherboard cover and create a gap.

Schritt 14

Insert an opening pick underneath the bottom right edge of the motherboard cover.
Slide the opening pick up along the right edge of the motherboard cover.
Twist the opening pick to release the plastic clips and pry up the motherboard cover.

Schritt 15

Use a pair of tweezers or your fingers to remove the motherboard cover.
The charging coil is attached to the motherboard cover and will lift up at the same time.

Schritt 16

Use a spudger to disconnect the battery cable by prying the connector straight up from its socket on the bottom left corner of the motherboard.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.

Schritt 17

Use a Phillips screwdriver to remove the five 3.8 mm-long screws securing the daugtherboard cover.
One of the daughterboard cover screws is covered by a white water ingress sticker. To unfasten the screw you can puncture the sticker with your screwdriver.

Schritt 18

Insert the point of a spudger underneath the top right edge of the daughterboard cover.
Pry upwards to loosen the daughterboard cover.

Schritt 19

Use a pair of tweezers or your fingers to remove the daughterboard cover.

Schritt 20

Use a spudger to disconnect the interconnect cable from the motherboard by prying the connector straight up from its socket.

Schritt 21

Slide one arm of a pair of tweezers underneath the metal bracket covering the interconnect cable.
Use your tweezers to lift and unhinge the metal bracket.
Remove the metal bracket.

Schritt 22

Use a spudger to disconnect the interconnect cable from the daughterboard by prying the connector straight up from its socket.

Schritt 23

Use a pair of tweezers or your fingers to remove the interconnect cable.

Schritt 24

Use a spudger to disconnect the charging port cable by prying the connector straight up from its socket on the bottom edge of the motherboard.

Schritt 25

Don't fold the cable sharply during this step to avoid damaging it.
Fold the charging port cable towards the bottom of the phone to access to the battery.
You might want to use a small piece of tape to temporarily stick the cable onto your working surface to avoid accidentally damaging it during the battery removal.

Schritt 26

Take care not to puncture or bend the battery with your tool—a punctured or bent battery may leak dangerous chemicals or cause a fire.
Use a pair of blunt nose tweezers to peel the right pull tab off of the battery until you can grip it with your fingers.

Schritt 27

Don't try to remove the battery all the way yet. The left side is still adhered to the midframe.
Grab and lift the right pull tab to remove the right side of the battery from its recess.
If you're having trouble lifting the battery out of its recess, apply a heated iOpener to the screen side for two minutes to loosen the battery adhesive.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device.
Only apply heat to the screen side to prevent the battery from overheating.

Schritt 28

Use a pair of blunt nose tweezers to peel the left pull tab off of the battery until you can grip it with your fingers.

Schritt 29

Grab and lift the left pull tab to remove the left side of the battery from its recess.

Schritt 30

Take care not to bend the battery during the removal procedure—a bent battery may leak dangerous chemicals or cause a fire.
Lift the battery from any remaining adhesive and remove it.
Don't reinstall a damaged or deformed battery, as doing so is a potential safety hazard.
During reassembly, temporarily reconnect the battery to the motherboard before you press it into place to ensure correct alignment. Disconnect the battery after it's seated.
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.
