OnePlus 12 Battery Replacement
Compatible model: OnePlus 12, CPH2581.
This repair uses a Genuine OnePlus Battery made for the OnePlus 12.
If your OnePlus 12 battery drains quickly, shuts down unexpectedly or struggles to last through the day, a battery replacement can restore reliable day-to-day use without wiping your data.
The OnePlus 12 does not normally show a simple battery health percentage in Settings, so the best signs are real-world symptoms such as fast drain, sudden shutdowns, swelling, heat, or the phone only working reliably while connected to power.
This is a book-ahead repair. The battery is sourced to order and is normally available within 1 working day. 2 Hour Express fitting is available once the part has arrived.
