iPhone 2.0 Hickups

I just found out the the iPhone 3G is not so perfect. The keyboard has a lag and the battery life is suppose to be so crap. Overnight the battery seems to be draining 50%-70% if uncharged. This is ridiculous. I've heard of rumors that even the 1st Gen iphones which updated the firmware to 2.0 has this problem. It might be a software issues so all you 1st Gen iphone owners hold up for awhile befre you update so that these issues might be resolved by apple.
