To obtain better battery performance, it is sometimes recommended to switch HSDPA to off. (I suppose the phone will not use power to search for HSDPA net).
To save even more battery power some people recommend switching WCDMA/3g off if you have poor 3g coverage. (for the same reason)
Does anyone now if switching WCDMA off automatically disables the HSDPA searching? Or will the phone search for HSDPA even if it cannot use it because WCDMA is disabled?
It would of course be much more simple just to disable 3G than being forced to disable both.

HSDPA is 3,5G, a faster version of 3G, so it should be sufficient to disable 3G.

Connect only GPRS and OFF wifi, set brightness to auto tune should do fine. And another thing. Put the phone to standby (total black screen) when not in use.
