Phone calls, and lots of email. No music. I've been off from work on vacation for the last 9 days so I didn't listen to music at all on it. With music, I get at least three days and between 6 and 10 hours usage.
Got a tip for us?

And not use it for internet??? What's the point? That's what the iPhone was made for. You're using it as a phone only. Maybe an iPod/phone, but still, that's not why people buy the iPhone. All the people talking about battery life are talking about issues when using the phone for its intended purpose.
Rated battery life for audio is 30 hours on a 3Gs and 24 hours on a 3G, so big whoop that you get 10 or so hours.
Tell me how you do on the internet.

I don't need it for intenet. I use it for email, music and some apps and a few phone calls. I have MBP here for internet.
I have experienced the same thing. However, let me say, before 3.1 both my 3GS and my wife's 3G had no problem making it through the day with average usage. We have Bluetooth, Location Services, and WiFi all on.
After 3.1, battery life sucked big time. I could go down 50% in 2 hours doing nothing except 15 minute fetch email. My wife's 3G would drain the battery completely in about 8 hours just in standby in her handbag.
We have turned off Location Services and appear to be back to pre 3.1 battery consumption levels.
One obvious though that I've had is that 3.1 introduced the "auto remote lock" feature through MobileMe. I'm wondering if something in the OS is causing the phone to poll too often looking for the lock signal... causing abnormal battery drain. Just a thought.
Definitely new problems for the battery for both of ours after 3.1

For those trying out the "location off" are you using the 3GS with 3.1?
Curious because I have the 3GS with 3.1 installed and my battery drains quick. I just now turned off my locations hoping to see a change.

iPhone 1G does not have an actual GPS chip, therefore no feature to actually turn off.
2 hrs, went from 70% to 68% with everything on except BT. In other words, HAVING LOCATION SERVICES ON DOESN'T AFFECT BATTERY LIFE.
And I have a 3G on 3.1. I haven't heard of a different issue for having a 3GS. IDKY a 3GS would behave differently though. IMO, something else is going on to cause battery issues, not strictly the LS being on.
I wonder if Maps keeps running in the background for some people on some devices?
You can test this by running (and then exiting) a really large 3D game (which will push Maps out of memory), or by power-cycling your device, and see if that improves battery life even with Location Services left on.

No idea either. LS can't be causing the battery drain unless something else tied to it is misbehaving.
Offline Maps to Decrease Battery Usage
Offline maps are useful for users with limited data phone plans, for users going to areas with no internet connectivity, or for users avoiding roaming charges. Locally stored maps are more responsive and battery life is longer since there is no 3-G, Edge, or Wifi access. Download maps for cities like San Francisco, New York, London, Paris, Tokyo, Los Angeles, and Manila easily with Wikimap. See
