Nokia Energy Profiler is a stand-alone test and measurement application for S60 3rd Edition, Feature Pack 1 devices (and onwards). The application allows developers to test and monitor their application’s energy usage in real time in the target device.

The application is available as a SIS package for S60 3rd Edition devices, but measurement works only in S60 3rd Edition, Feature Pack 1 (or newer). Older devices can still view files. 

Nokia Energy Profiler 1.1 has the following views:

• Processor

Hi readers,

I've just found an interesting article at Adobe devnet: Developing Flash Lite applications with dynamic layouts. It's written by David Brown Lead Developer of Emerging Technology at Agencynet.

"In this tutorial I describe the process I used to develop the dynamic layout of the Bacardi® Mobile Cocktail application. I'll cover how to react to environment changes, such as the current time of day, and how to implement automatic Stage size and orientation switching. Automatic adjustment is especially important for devices such as the Nokia N95, because it is capable of changing its resolution. For other devices, you will learn how to manually alter the orientation of your application to mimic that functionality. " - David Brown

It's a really great user experience made in Flash Lite. There's also a promotional video, check it out: Bacardi Mobile Demo.
