I recently updated my iPhone 3G to latest firmware from 2.2.1 to OS 3 and now I am noticing it has reduced the battery life. It used to work at least 24 hours without charging, now when i leave fully charged iPhone at mid night and look it in the morning it lose 60-70% of battery just in 8-9 hours. Anyone having the same problem?

I upgraded last week and my battery seems to be fine :/

Are you jailbroken? If so, what jailbroken apps do you have installed?

And did you upgrade or restore? If you upgraded, I suggest you restore because upgrading is like a Windows OS installation, if you use the upgrade option on a PC, your bound to run into more problems, same with the iPhone.
