But the tech nerd inside me made me switch to the nexus one.

The point however is that for the first 2 weeks I did not take a data connection and was using it only on a wifi and had a horrible battery life.

For some reason when i got the data plan with tmobile and starting using that the battery improved significantly.

Somehow makes me think something is wrong with the wifi module.

Try to turn of wifi and see if it has a positive impact.
