Introduction

A smartphone : a mobile phone with highly advanced features.

A typical smartphone has a high-resolution touch screen display

Internet connectivity

Web browsing capabilities

PC like functionality

IBM developed first smart phone in 1993

Background

Smartphones support a large set of applications

Many applications consume significant battery energy

Power consumption has been critical for smartphones

Developers lack tools to analyze energy consumption of smartphones

Smart energy monitoring system (SEMO)
