Battery Life and
Performance
Optimisation

Battery life can be affected by various factors such as device settings, environment and usage patterns. Understand these factors to use your battery more efficiently and for a longer period of time.

Factors Affecting Battery Life

Environment

Battery consumption increases in areas with weak or
overlapping signals or with increased screen brightness
under strong sunlight or any other light source.

※ Galaxy offers Adaptive Brightness to optimise screen visibility based on
the light intensity of the environment.

Usage Pattern

Galaxy’s AMOLED Display has a high contrast ratio that will
increase battery consumption. Increased screen brightness,
longer intervals before screen timeout, high-performance apps,
streaming high-resolution content, and location services or
other allowed services will also increase battery consumption.
