Xiaomi BN56 Original-Capacity Replacement Battery (5000mAh)

The BN56 is a massive-capacity internal Lithium-ion Polymer replacement battery engineered by Xiaomi for its heavily distributed Redmi entry-level line and select Poco models. Because these phones are built as budget battery champions, a degraded factory cell will rapidly lead to performance drops, sudden shutoffs at 15–20% capacity, or the device getting stuck in a loop on the “Redmi” or “Poco” startup screen. Replacing it with a premium BN56 cell completely restores the device to its factory-standard runtime.
