Abstract	Many users would be satis ed if their Android smartphones simply lasted a full day on a single charge. Unfortunately, many users must carry their chargers with them and recharge several times a day under normal usage. Popular online suggestions to extend battery lifetime include manually managing hardware components such as GPS, 3G, Wi-Fi, and Bluetooth and turning them o when they are not in use. For any system to run e ciently, a power management system is necessary to manage the power consumption by that device. For an Android device, it supports its own Power Management (on top of the standard Linux Power Management) designed with the premise that the CPU shouldn't consume power if no applications or services require power. This takes care of the applications and sevices. There have been multiple attempts to characterise those energy de- mands; both to save or to allocate energy to the applications on the handset. However, there is still little understanding on how the interdependencies between resources (interdependencies caused by the applications and users' behaviour) a ect the battery life. The battery is taken up by WiFi and mobile data network (GPRS/3G) to a great extent. The battery optimization is a very extesive problem to be solved, the aim of this project is to identify which application in Android phone is using up most battery in terms of CPU, memory and battery usage. Many applications were developed to collect data for battery consumption by developing and running a dummy application which used CPU, memory or data at a time. Application was also developed to collect summaries of battery and data usage for applications like Gmail, Facebook, Whatsapp and browser running together. The data was further analysed and graphs were plotted accord- ingly. It was observed that application requirng maximum data usage uses more battery than application which requires CPU and memory.
