if your intrested overclocking might help in a dramtic way
if you find it risky then atleast consider it
am writting a script that will end this battery sucking problem
uploading it tommorw hopefully
my battery usualy last 1 day under mid-heavy use
but now cause of the script am using .i saved upto 50% as it should be flat out empty by now but i still got 50%
If you have ApMeFo or catorize, there's a glitch that makes hildon-desktop -always- take 2% cpu(even after uninstall of the app). This eats through battery significantly; if you notice hildon-desktop showing up via conky all the time, you may want to install this patched version.
Also, putting the phone into airplane mode/offline mode increases battery life a LOT. But, it also removes your ability to receive calls, so...
