Plan and Perform a Battery Replacement — Smartphone Academy

Replace a worn battery using model-specific isolation, adhesive removal and calibration procedures while treating the cell as a fire risk.

Core Ideas

Disconnect the battery before other internal connectors whenever the official sequence permits.
Use only the specified adhesive-removal method and never bend, puncture, squeeze or lever against the cell.
Inspect the replacement part, connector, date code and dimensions before removing protective films.

Decision Rule

If the cell does not release using the documented method, stop; extra force can convert a routine repair into thermal runaway.

Apply It On Your Phone

Document battery health before replacement and repeat the same tests after calibration and several normal charge cycles.
