I purchased my iPhone on Friday. The battery seemed to hold a charge very well over the weekend. But today I noticed that when I was in a 3G area the battery seemed to lose its charge very quickly. If you went to the, settings/general/usage it showed that I only had 2 Hours 25 Minutes of usage but the battery was almost completely drained. Help!
Mac Book Pro 15.4", 2.4GHz, 4 GB Ram,
Mac OS X (10.5.4),
iPhone 3G
If you don't plan on using 3G then turn off the 3G. That does use a lot of battery usage, if you compare with 2G that is. Also if you are not using Push, then i suggest turning that off too, also the location thingy as well.

Yeah, but isn't that's kinda the whole reason for buying a 3G iPhone. I read all of those statements before I ever purchased mine. And I hope Apple doesn't share the same sentiment, because if so the phone will be returned.
The bottom line is 3G uses a lot of power compared to EDGE, so it will eat power.
Push mode requires a constant connection to the Internet, so it will eat power.
GPS reception and updating the associate Google map will eat power (unlike a regular GPS device, the iPhone has no built-in maps and thus must download a new map from the Internet every time you move.)
Combine those things and you get a lot of "idle" power draw.
If you use your phone just for calls on an EDGE network, you'll get maximum battery life.
It's not just the iPhone; all smartphones use battery like that and arguably the iPhone has the best battery life of any 3G-capable smartphone.
You are, of course, welcome to return your phone if its capabilities aren't what you had expected or hoped; Apple can't please everyone.
All true, but gee I'd love to see Apple conjure up a "power management" app so that I can set a range of wireless profiles (four or five should do it) depending on what I'm doing, rather than having to manually turn on/off 3G, WiFi, location services, bluetooth as is the case now.
Just posted this message below to apple's feedback for iPhone. Perhaps Apple will hear this if more of us post messages like this. Thanks. LTK

I just bought an iPhone 3G and heard that I can stretch the battery life if I turn off the 3G, GPS (location services) & Wifi radios when they are not in use. I did this for the last 2 days but found this to be terribly inconvenient & thought his can be easily automated.
Perhaps Apple and add a feature in the form of a switch which turns off these radios when the "standby" button at the top is pressed to turn off the screen. I can not use any of the radios if the screen is off anyway. The only inconvenience I can see is a slightly longer response time when the screen is turned back on but I think I would live with is if this meant 20+% more battery life.
