is there any way to increase the battery power?

hope to hear from you all
Disable Wifi if not needed
Disable GPS (why would you need it under normal daily use anyway, unless you are toying with apps)
Reduce the frequency of data sync, eg your RSS reader, your news and weather, your contact sycn, your email pop download frequency, your gmail sync, facebook notification..etc. Put a longer duration.
Reduce screen brightness, you don't need it to be glaring bright, unless you are outside.
Check if you have apps running in background and consuming your CPU still. I use OSMonitor app which is quite cool
Are you in signal weak spot area? It will drain your batt even more. I heard that putting your hands at the bottom of the phone somehow deteriorates the signal.
Put a faster screen timeout.
Get the OTA update
Download netcounter from market. You'll get a hint from it on data transmission. If it kept going up frequently, you have something running that is doing data transfer work in bg.
Once i've tried disabling 3G data all together for few days...the phone lasted 2 days without charging and still with juice left.
