I've managed to squeeze 2 days and 6 hours out of my battery...admittedly with low usage.. a few calls one overnight backup and reading about a dozen or so emails n maybe a few web searches.
but my point is this.
the phone's biggest drain is the screen and the cpu.
did you know that the cpu is buzzing at full speed even with the screen off !!
by upgrading your phone to the new build as Suze says and by gaining root access to your phone, you can install an application called setcpu which needs the root access to work.
This lets you set the cpu to a crawl of 245MHz when the screen is off, which vastly increases your standby time.
The reason I know this is because by installing the setCPU app when the phone is not 'rooted' , you can see the cpu speed in read only mode and confirm for yourself that it always runs at full speed.
Other things you can do which are less....drastic but have a lesser effect is.
make the screen turn off fairly quickly after you have left it alone, as screens are high battery drains.
Also, install a widget called quick setrings that allows you to turn off the bluetooth and wifi and gps if they are left on.
make sure your apps that use these are setup to turn them back off again when you finish.
you can install an app called task killer that you can set to stop programs after you leave your phone alone for a while , but this may save you more memory than battery..
oh..yea install a widget called antennawidget or similar, it shows you the exact signal strength of the phone in dB and anything below -111 is call dropping bad and the phone uses up extra battery trying to find a better
cell tower. Other apps like antenna show you a google map with a line between your phone and the tower you are connected to
that's all I have right now ..
