Background app processing - CPU usage
Screen - brighter and more screen time, means more power usage
Radio signals, cellular connection, wifi and bluetooth all use power.

The first thing to wear out in most mobile computing devices is the battery. Rechargeable batteries only support a certain number charge cycles before the battery needs replacement. So from those core principles let us begin.
