I've just bought my first Android phone, an HTC Legend running 2.1 which I love. What I don't love is the battery life! I've been experimenting with different methods of conserving the battery and would like to hear what others users are doing. At the moment I switch off Wifi when I'm not at home and switch off GPS when I'm out all day. I also use a task killer to stop auto-updating apps I don't want open. I have some applications that check for updates frequently, email, exchange client and Google Listen, how does this impact of battery life? What about battery management apps? I've seen apps that control aspects of the phone but they seem overly complicated to configure, i.e. it's unclear how different settings will affect battery life. I've come across an app called Data on Demand that switches to 2G when the phone is on standby or on a schedule which seems very promising however there's no obvious way of verifying that it's working! Finally, anyone using Locale for power management? Cheers.
