Optimizing Power Consumption in Smartphones: A Comprehensive Survey

Smartphones are being used extensively these days and they are capable of replacing conventional computers and laptops to some extent. The main reason is that smartphones are smaller in size and lighter compared to bigger and heavier computers or laptops. The battery powering a smartphone also has a size constraint and hence the capacity. Though new generation communication systems such as 3 Generation (3G), 4 Generation (4G) and 5 Generation (5G) can provide the best services to users, they draw considerably more power in smartphones. This limits the battery backup of smartphones and hence the battery life. This survey presents various ideas and proposals published for reducing the power consumption in smartphones which support new generation communication standards.
