I just got the iPhone 4 for Verizon a few days ago and I am a little concerned with the battery life. I've turned off bluetooth, wifi, all notifications, I've set my email push to manual, my brightness is at 50% and I've turned off all apps except phone, texts, contacts, and settings. My Battery is currently at 89%. 45 Minutes of usage. 1 hour and 45 minutes of standby. Calltime 15 minutes. Is this normal? If not what can I do about it? Will Apple do anything? Thanks!
