1. Built-in Android task killer
Android features its own little task killer, but it’s very, very well hidden. Manually close apps by going to Settings > Applications > Manage Applications then pressing Menu – and filtering the results by running apps. If you can be bothered with all that, you’re than able to force close anything that’s running.
2. Lock your phone
Setting an unlock pattern adds a small layer of additional security to your phone – just remember to wipe the tell-tale finger smears from the screen.
3. Keep the screen on while charging
It’s often handy to have the screen stay on all the time, especially if you tend to recharge your phone overnight and use one of the fancy apps that turn your phone into a nice 1980s clock radio and. Go to Settings > Applications > Development and tell the screen to stay on while charging. Just don’t tell your environmentalist friends you’re burning through electricity like this.
