Frequently Asked Questions

Does the reference EB-BN985ABY fit the standard Galaxy Note 20 model?

No. This battery was designed exclusively for the Galaxy Note 20 Ultra, having different physical dimensions and specifications from the base variant.

The phone does not turn on, does replacing the battery resolve it?

If the previous component is completely degraded or holds no charge, the replacement resolves the fault; if current draw remains at zero even with new power, the problem may lie in the charging connector or main board — confirm diagnosis.
