If you’re a Windows Mobile user who synchronizes with a corporate or hosted Exchange server using Activesync, you can squeeze out more battery life out of your device by tweaking a few settings. Below I’ll describe some of the settings you can change, and how to change them. These instructions apply to Windows Mobile 6.0 and greater when synchronizing against Exchange 2003 SP2 or greater. To find out what version of Windows Mobile you have: If you have a touch screen, go to: Start -> Settings -> the ‘Systems’ tab -> About. If you don’t have a touch screen, go to: Start -> Settings -> About.
