Battery Life Optimisation
Battery life can be affected by various factors, such as device settings, environment, and usage patterns. Understanding these factors and using the settings will help you use the 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
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.
