How - or what\'s the best way - to retrieve the device\'s current battery level in .NET CF 3.5 on Windows Mobile 5 and 6?
To add to CJ's response you can find a code example of how to get detailed battery information from http://www.codeproject.com/kb/mobile/Wimopower1.aspx . This information includes the batter's power level, temperature, whether it is charging or draining, and the amount of current being drawn.
