I just bought a brand new iPhone 4 on Tuesday from Virgin Mobile and updated it with the latest software (I think it's iOS 4.3.3?) and have notice that the battery is terrible, it's probably worst then my really old iPhone 3G. I have 3G turn off pretty much all the the time, I turned off ping and EQ. I only have push for Facebook and eBay. I only have location on for Facebook, maps and compass and my brightness. I only have 1 email account added and I have fetch data manually. My battery is at 80% right now with 9 hours standby (on airplane mode) and 1hr 35min of usage, it's that normal for an iPhone 4? Oh and I've also tried restoring the phone but it hasn't helped.
