Symbian Apps: Energy Profiler

The Nokia Energy Profiler is an application for S60 3rd Edition Feature Pack 1 and S60 5th Edition devices. It gives developers and device users information on the following:

  • Power consumption, as well as battery voltage and current.
  • Cumulative energy consumption.
  • Processor activity.
  • RAM use.
  • IP-network speeds.
  • Mobile-network signal strengths.
  • 3G Timers.
  • WLAN signal strength.

In application testing, this information is used to identify excessive power consumption by an application. By addressing power-consumption issues, developers are able to provide software that performs optimally on S60 devices and that delivers a great user experience.

What’s the latest news about the Nokia Energy Profiler?

Nokia Energy Profiler v1.2 has been released. This new version provides:

  • Touch UI support with tap areas, icons, and the ability to scroll graphs by dragging them. In addition, manual screen shots can be taken using the power key on touch-based devices.
  • New data collection for:
    • WLAN received signal strength in dBm.
    • 3G cellular network T1 and T2 timers.
  • New graphing features, including the ability to select a time period (the paint graph-area feature), a grey background to indicate the backlight is on, a red line to indicate that a charger is connected, and battery current shown in milliamperes (mA).
  • Improved CSV output, including time stamped data items and all data values.
