Nokia sweetens juice-monitor app

Data rates, signal strength and RAM, oh my!

Boost IT visibility and business value

Forum Nokia's very-useful-to-a-select-minority power usage logger has been expanded to log a load more system states, which should equally expand the interested market for the app.

Nokia's Energy Profiler, an application that monitors and logs the power consumed on a S60 FP1+ device, has been updated. Version 1.2 can now log CPU load, RAM consumption, network data flow, network signal strength, Wi-Fi signal strength and 3G Timers state as well as power consumption via a variety of metrics - all at the tap of a finger, where supported by the device.

The application has been developing since 2007 and the latest version, which is free to download, can create CSV files for easy importing into a spreadsheet for analysis. The original application was really only of interest to hardcore geeks; most users know that playing back a movie really hurts battery life, and don't need to know any more, but logging signal strengths is of interest to a much wider community. Combining such a thing with a simple GPS logger could produce a network-coverage map, Wi-Fi or cellular, with the minimum of effort.

The application is still primarily of interest to engineers, and the interface reflects that; but the provision of APIs for integrating the monitoring capability into other applications is interesting and should lead to some mobile phone apps which are about as far from making phone calls as it's possible to get. ®
