On 9 March Nokia released the version 1.2 of Energy profiler a Symbian application you can use to monitor how the power consumption of your phone changes when you try a J2ME application (or other type of software).

As stated in the Nokia website:

"It is an application that enables developers and device users to examine power consumption and several other parameters on S60 devices. The reporting provided by the Nokia Energy Profiler enables developers to identify and improve application functions that consume excessive amounts of power and thus to create higher-quality applications."

The application works on Nokia series60 3rd and 5th edition devices.

The features added in the version 1.2 are:

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

Many phones can work in normal or landscape mode nowdays. For that reason it would be great if our application could adapt itself to a mode or the other redrawing the user interface with the new dimensions.

The way to detect when a phone switch to and from the landscape mode is the implemetation of the sizeChanged method in the Canvas class and do all the changes you need.
