The Battery life ATLI EON refers to the amount of time the device runs before it needs to be recharged. For ATLI EON, the battery life for time-lapse shooting depends on the shooting interval, lighting condition, and Power Saving. Without Power Saving enabled, the other two factors are not significant and the estimated battery life for a fully charged new battery is about 7 hours. With Power Saving enabled, the battery life is greatly extended as shown in the table below.
