GIGAPACK poco x3 gt 5g battery 4900mah li-polymer bm57 compatible

This replacement battery is designed for the Xiaomi POCO X3 GT smartphone and carries the model designation BM57. It offers a capacity of 4900 mAh and uses lithium-polymer technology, which allows for a thin, lightweight construction. Weighing 100 g, it is intended to replace the original battery directly.

Lithium-polymer batteries belong to the lithium-ion family. They provide a high energy density, can be recharged repeatedly and lose capacity only gradually over many charge cycles, as they show no significant memory effect. Their cells can also be shaped more flexibly, which is why they are commonly used in slim devices.

Capacity, measured in milliampere-hours, indicates how much energy the battery can store. The higher the value, the longer the device can run between charges. The voltage and the number of charge and discharge cycles are further characteristics worth considering when choosing a replacement battery.
