Lithium-ion Battery

Learn about the Lithium-ion (Li-ion) battery,
which is high energy density, long-lasting and safe.

Batteries are consumables, and their lifespans are affected by their usage patterns and environments.
If you find yourself charging your phone too often, and your battery life has noticeably diminished, visit your local Samsung Support Center for advice.

Battery Decline

Normally, signs of battery decline include drastic decreases in battery life and unexpected shutdowns.
Learn about unexpected device shutdowns.

- Electrochemical Decline of the Battery

These events occur after repetitive battery use, resulting in electrochemical efficiency.
High levels of decline could cause voltage drops, resulting in device shutdown to preserve the device's electrical components.

- Temporal Shutdown due to Usage Environment

An extremely cold environment may cause a greater drop in voltage.
In this case, the device might shut down temporarily to preserve its components.

Signs of Battery Decline

As battery efficiency decreases, the battery may noticeably deplete or shut down,
even if the screen displays plenty of battery power remaining.
If you are having issues with a declining or inefficient battery, visit your nearest service center.
