OnePlus 3 Battery Replacement
Verify your battery model before proceeding, as incorrect models may lead to incompatibility issues.
- Battery discharge warning: Reduce the battery level below 25% to minimize thermal risk during disassembly.
- If your battery is swollen, take necessary precautions to avoid injury.
- Remove the frame clips using a suitable tool, as this may be the most challenging part of the repair process.
Step 1 | SIM Card Tray
Insert a SIM eject tool, bit, or straightened paperclip into the hole located between the SIM card slot and the power button.
- Press firmly to eject the SIM card tray.
- During reinstallation, ensure the SIM card tray is properly oriented — it fits only in one direction.
Step 2 | Back Cover
Remove the two 2.6 mm T2 screws from the bottom edge of the phone.
Step 3
Improperly opening the device may damage the display panel.
- Read through these steps before proceeding to ensure correct procedure.
- Pry at the recessed seam between the back cover and plastic frame.
Avoid prying near the display panel seam, as this will damage the display assembly.
- There are 14 clips holding the frame against the rear case; be aware of their location during disassembly.
- Pry carefully at the recessed seam between the back cover and plastic frame.
Step 4
Accidental power-on can damage internal components.
Ensure phone is turned off before proceeding.
- Position a suction cup near the display's bottom edge.
- Pull on the suction cup with steady, strong force.
- Press an opening tool into the frame seam near the suction cup, wedging it between the plastic frame and the back cover's lip. Use substantial force, as tolerances are tight.
A new opening tool with a sharp edge can aid this step.
Never use metal tools, as they may crack the screen.
Step 5
Slide the opening tool along the phone's bottom edge.
- Keep the tool's edge guided by the seam as you approach the left corner.
- Continue to guide the tool around the left corner of the phone.
Step 6
Slide the opening tool along the long edge, releasing clips as you go.
- If necessary, use the flat end of a spudger or opening pick to aid in releasing the top-left corner clip near the alert switch.
Step 7
Wiggle the frame gently to release top and right edge clips.
- Lift the screen up and remove it.
- Test your phone's functionality before reattaching the back cover during reassembly.
Failure to test functionality can result in damaged components.
Reattach the back cover:
- Align top edge of frame with back cover, ensuring top clips fit into place.
- Squeeze along long edges of phone to snap remaining clips into place.
Step 8 | OnePlus 3 Battery Disconnect
Beware of accidental contact with sharp points.
- Use a spudger to pry up and disconnect the battery connector from its socket above the top right corner of the battery pack.
- Bend the connector away from the socket to prevent accidental contact.
When re-attaching, align carefully and press down on one side until it clicks into place; repeat for the other side, avoiding the middle area to prevent pin bending and damage.
Step 9 | OnePlus 3 Interconnect Cable Disconnect
Remove the 3 mm Phillips screw that secures the cable bracket.
- Remove the cable bracket.
Step 10
- Use the point of a spudger to pry up the interconnect flex cable from the motherboard, located above the battery.
- Repeat this process for the daughterboard flex cable.
Step 11 | Battery
Use the point of a spudger to carefully pry up and release the interconnect flex cable from its connection on the daughterboard, situated beneath the battery.
Step 12
Remove the interconnect flex cable.
- Bend the daughterboard flex cable away from the battery.
The Sub connector will cause a malfunction if connected to the motherboard; ensure the Main connector is connected instead during reassembly.
Step 13
Do not puncture the battery pack.
- Use the opening tool to release adhesive tape holding the battery.
- Pry off tape from both sides of the plastic frame edge.
Step 14
Remove the battery's protective cover by peeling it upwards.
Step 15
- Brace the phone frame against a stable surface.
- Pull the clear pull tab upwards with steady force until the battery loosens from its recess.
- Swing the battery completely out of its recess and remove any remaining adhesive.
Apply high concentration (over 90%) isopropyl alcohol along the battery seam if removal proves difficult.
Step 16
Reusing a bent or stressed battery poses a safety hazard.
- Remove the battery from the frame and clean any remaining adhesive residue.
- Batteries must not be reused, as they may cause harm if damaged.
- If your replacement battery lacks a pull tab, transfer the old tab to ensure easier future removals.
- When installing a new battery, connect it temporarily to the phone to confirm correct alignment.
- To attach a new battery to an existing frame:
- Remove adhesive strips from the pre-cut card or cut them from Tesa tape and apply to the designated area.
- If using a new screen assembly, remove the orange liner to expose the battery adhesive for the replacement battery.
