I have heard (based on alotta other forums and experience) that the battery life is much worse if your iPhone is unlocked and jailbroken. So when posting your experiences with battery life tell us if your iPhone is jailbroken or not.

My personal experience: I am jailbroken and unlocked and I am watching the battery life go down a % every 10-15 minutes which is really annoying. I do not have 3G on cuz its not compatible with T-Mobile. Yesterday I took out my sim card at 5pm batterylife was at 53% I came back this morning at 10am and where do you think it was? 53% ! It hadn't moved! Sure enough I put the SIM card back in about 20 -25 minutes ago and we're already at 52%.

I don't know if this can be fixed via upgrading to the 3.1 firmware or is it a defect in the battery? I certainly have no idea why it should use more battery if its unlocked and jailbroken...

Any ideas?

Can't help with comparisons on jailbreak vs non, but if you have the SIM card out then you are not pinging the cell towers and thus your iPhone is in airplane mode and nothing but an iPod. No cell network or wifi will allow the battery to last much longer.

I would say that your jailbroken phone is not optimized for the T-M network and id trying extra hard to stay connected. Could that be? It certainly makes a difference on any phone if you have a good cell signal or not.
