Battery drain is definatley the worst aspect of the N900 in my experience of having it over the last month..

However, there are some way to mitigate it:

- I use an in car charger whenever I'm streaming or playing music in the car
- Use Autodisconnect to disconnect wireless or GPRS connections when not using then
- Use the app that lets you switch to 2G only when you don't need 3G (forgotten what it is called)
- Buy a desktop charger and 2nd battery

Since I did all those things the battery life (which I knew was bad before I got the phone) has stopped annoying me. Loads of other ideas in the various battery life threads.

Hope you continue to enjoy your new device

Hope that helps!
