The paper presented discusses the revolutionary Android Apps, its effect on the Android smart phones and disadvantages of having apps running in background along with some suggested improvement. The android apps are made from scratch using Java as a basic language, but apart from that, a particular App may use other components of the smartphone like the various CPU, GPU, RAM, and Battery. The apps are capable to run in background also. This enhances the multitasking feature of the android operating system, but the major disadvantage of this feature is that the apps running in background starts accumulating and thereby consuming excess RAM & memory. Due to this, there is a shortage of the necessary amount of RAM and as a result, the processor slows down ultimately resulting to app crashes and increased processor temperature. The abnormal heating eventually causes battery drainage at a higher rate.
