My friend Tina showed me this over the weekend, and it seems to be working quite well so far…
Find a screen with at least one blank row of applications, then Tap and hold on the screen to bring up the Personalize screen.
Under the “Add items to Home” section, select “Widget”:
Scroll down to the “Power Control” widget, and tap to select.
The Power Control widget will let you turn on and off Wi-Fi, Bluetooth, GPS and Synchronization. It will also allow you to set the screen brightness to low, medium or high. Since the screen is one process that seems to eat up the most energy, this setting will have the greatest impact on battery life. Setting screen brightness on low will only work at night or in very low light situations. Medium is good for most indoor situations and everyday use. High is pretty much required if you are outdoors or in a very bright light area. Obviously turning off Wi-Fi, Bluetooth and GPS when not in use will also contribute to extended battery life.
