Saving battery on smartphones
If you have a smartphone, you are probably disappointed by the battery life. My HTC Legend can run for not more than one day.
Donncha O Caoimh, the author of WP-SuperCache, gives a couple of tips to help reduce energy consumption. Changing the screen brightness is probably the first energy saver. Obviously turning on/off the Wifi, Bluetooth, 3G or even GSM, when needed is also a good tip. The Dazzle widget really helps to do that.
