Three days on battery with Xperia X10 mini pro and Tasker

After installing Tasker on my Xperia X10 mini pro, and configuring it
to check my email every one hour from 6 to 21 hours, I have seen an
improvement in my battery life.

I have also configured it to only connect to my Wifi (turn it on) when
I am near my office or house (using a state of [cell near]).

So it turns it on (data, sync and wifi -if near home or office-) for
three minutes every one hour.

With this setup, I have my battery run a complete three days before reaching 5%.

If you need some help to configure it, let me know in the comments section.
