How does the OnePlus 11 battery replacement work?
- Battery diagnosis
OxygenOS battery display plus our voltage measurement at the battery module. Below 80 % capacity or over 500 full cycles, we recommend a replacement.
- Open the display carefully
The OnePlus 11 is opened with a special suction cup, the flex cables are released, and the panel is fixed on the stand.
- Release the battery adhesive strips
The 5000 mAh cell is fixed to the frame with pull tabs. We release it with isopropanol 99 %, never with a screwdriver lever.
- Fit the certified cell
New Li-polymer cell with identical capacity, 3.87 V nominal voltage, exact form factor. Connector on the mainboard, adhesive on the frame, contact pressure controlled.
- Re-bond the display and calibrate
New seal on the frame, panel bonded under pressure, 30 minutes curing time. Then a full charge for calibration.
- Test and fast-charge check
OxygenOS battery health, voltage curves, charging speed with the original OnePlus SUPERVOOC 100W charger.
