10% or 40 minutes of music playback seems a bit strange.
I used mine all day today from 8 AM to an hour ago and it's at 18% life left. Pretty good by me for how much I used it.
I keep push notifications off and brightness up 3/4th.MacBook Pro 2.4 GHz C2D, Mac OS X (10.6.3), 200 GB HDD 4 GB Memory GeForce 8600M GT 256 MB

Currently Being ModeratedJul 14, 2010 2:48 PM (in response to RoninNY718)There are a few things that really drain the battery. They include:
1. Mail settings that retrieve mail every x minutes. Push service for email is battery intensive. Shut it off and do this manually if you can. You can reduce the frequency that your phone looks for email on the server (15, 30, or 60 minutes) as well.
2. Make sure Bluetooth, Wifi, and to a lesser degree Location Services are turned off when you're not using them.
3. Push notifications from applications can drain battery. Go into settings Push Notifications and turn off any ones you don't absolutely need.
At night, you might consider putting the phone in Airplane Mode or if you still need to have your phone on at night for whatever reason, just turn off 3G (just remember to turn it back on when Web searching or you'll be on the Edge network).
Also, if it's a new iPhone and you haven't already drained the battery, you should do so. Just let your phone die from usage and plug it making sure to charge it to 100%.iPhone 4, iOS 4
