  • the one or more applications being executed in the background utilize the system resources and consume power (i.e., battery power) of the portable terminal, but any device operating in relation to any executed application also consumes power of the portable terminal.
  • power i.e., battery power
  • any device operating in relation to any executed application also consumes power of the portable terminal.

  • a list of the one or more applications is automatically (or manually by the user) displayed, so that the user can terminate one of the one or more applications.
  • a preset number of applications e.g., more than ten applications
  • only applications utilizing a preset proportion e.g., 3%) of the system resources are automatically (or manually by the user) displayed among the ten applications, so that the user can selectively (or collectively) terminate one or more of the applications, which are being executed in the background and utilize a high proportion of the system resources, thereby consuming large battery power and degrading the system performance.
