SMARTPHONE ANNUAL ENERGY CONSUMPTION

The energy consumption during the charging process primarily depends on the charger's efficiency and battery capacity. Typically, smartphone chargers have an efficiency of around 70-90%.

Also, the energy consumption during active usage varies based on the tasks performed, screen brightness, app usage, and connectivity. Activities like gaming, video streaming, or using power-intensive apps may consume more energy than lighter tasks like texting or browsing web pages. Higher screen brightness settings also require more power.

Individual usage patterns and habits greatly influence energy consumption. For instance, frequent use of power-intensive apps, heavy gaming, or prolonged video streaming can drain the battery faster, resulting in higher energy consumption. Conversely, conservative usage and enabling power-saving features can reduce energy consumption.
