I'm loving my HTC Touch Pro2, but the battery is killing me.

I have conservative settings, turn off the screen when I'm not using it etc. I mostly use it for internet and a little texting, almost no phone calling, occasional wifi router.

But it's pretty much dead after 8-10 hours. Is this normal?! Not even 1 full day from 100% charge?

What can I do here?
