Here is some feedback from someone who is still on Nokia 6110 because the N900 is STILL not available in Switerzland.

When I first got my N6110 I was supriesed that my battery would not even last 2 days.

So here is what the problem was. At home I have a very poor GSM coverage and no 3G at all. My phone was set to dual mode.

I told the poor battery performance to my sales person and he showed me how to switch the phone to use GSM only.

He told me that the problem was that the phone was contantly searching for antenna coverage. And that draind it.

Setting it to GSM only allmost doubled my battery life back then.

I think if you life right under an antenna you will have longer battery time then if you are further away.

So maybe one should be looking for a good coverage and use the better GSM or 3G depending on needs.

Maybe a full coverage at 3G will drain the pattery less then a very bad coverage at GSM .

Just my two cents on this.
