Nokia Energy Profiler for 5th Edition
See the Power of Software with Energy Profiler

Nokia Energy Profiler is a stand-alone test and measurement application for Nokia S60 3rd and 5th Edition devices aimed at extending the battery life of Symbian S60 devices.

Nokia Energy Profiler is a free S60 development tool that allows real-time power consumption measurements while running applications in the device.

Without the Nokia Energy Profiler, some applications may look as if they work perfectly, but cause batteries to die rapidly because power consumption checks were not made. With Nokia Energy Profiler, everybody can make batteries last longer.

Although it is mainly aimed to developers to test and monitor their application’s energy usage in real time it can be very useful tool for regular users especially for those that have problems with huge battery drain to detect where the problem is.

After the test is executed, it allows exporting the results in various formats for later analysis, Excel csv format for example.

Nokia Energy Profiler v1.2.

• Touch UI support.
• Capture of WLAN received signal strength and 3G cellular network T1 and T2 timers.
• New graphing features.
• New CSV output features.

Touch UI support

On the touch screen devices, t he joystick’s Up, Down, Left, Right, and Select keys are mapped directly to the screen on phones with a touch UI. Keyboard shortcuts are represented as toolbar icons (Figure 01).

Scrolling the results graph can be achieved by holding and dragging the graph. A long-tap access shows screenshot, extended zoom levels (in scale extremes), and continuous scrolling. Time-selection mode is through double-tap and hold, and then painting an area.

Figure 01: Use toolbar icons or Options to access other features.

Figure 01 shows toolbar icons in portrait and landscape orientations. The basic toolbar consists of three icons: change view, toggle between instant and average bars, and access more icons. More icons are (row by row from top-left in the portrait screen shot of Figure 01): add grey marker, toggle landscape/portrait, dual-view mode, zoom in time scale, change corner indicator, and zoom out time scale.
