With Power-saved application we can save a lot of energy in our Nokia N900 of a very simple way. Simple and effective Script, highly recommended to extend battery life.

To save energy this script does the following:
- Sets internet connection mode to “Always ask” (available under Settings -> Internet connections -> Connect automatically).
- Disconnects current internet connection.
- Switches cellular radio into 2G-only mode.
- Disables automatic email send&receive in Modest email client.
To install Power-saved we open xterm and access as root. Then go to the directory where we saved power-saved.sh and execute it, for this type:
power-saver.sh
To disconnect it type:
saver.sh power-off
Download | Power-saved.sh

Useful and interesting!
to enable :
sh power-saver.sh
to disable:
sh power-saver.sh off

Brilliant idea by ther originator but I already have my settings as above without the script but still can’t get more than 5hours of battery life always online. I hate my device for this! Maybe underclocking is my only hope then…
