Replacing the battery on the phone without triggering the "unoriginal battery" error message is possible with the new BMS flex strip battery.
This maintains compatibility with the Battery Management System (BMS) of the original battery.
You only need to connect the original BMS strip to the battery's BMS flex strip.



- Lithium-ion battery
- No welding contacts required
- 0 charging cycles
- Eliminates the non-original battery detection error

  11. Use the original black adhesive to cover the BMS flex tape.

  12. Connect the battery connector to the motherboard of the mobile device.

  13. Do not turn on the mobile device using the power button.

  14. Connect the device to a power source using a charging cable and let it turn on automatically.
