If you're doing sensible things, like turning off push e-mail when you're in the office, not keeping 3G on when you're in patchy coverage, etc. it should last you the day. I live in London, where there's 3G signal _everywhere_, which helps a bit.
We really need a developer to step up and design an iPhone app that would let you save and easily switch "states" that could flip all of the various power-management affecting settings at once. (3G, push, GPS, WiFi, etc.) Someone who does this could easily sell it to virtually every iPhone owner.
Why do you consider "turning off push e-mail" and "not keeping 3G on when you're in patchy coverage" sensible? Push email shouldn't be much more expensive in terms of battery life than SMS. The phone should know enough about what you need to turn 3G on or off automatically.
Absolutely agree. The idea that the user is responsible for diddling around with complicated settings in order to get an essential feature* to work flies directly in the face of the way Apple products are supposed to work. I don't have one: is it really that bad? That's a showstopper for a huge number of users if true.
* And yeah, I'd put "24+ hours of battery life" way up there on the list of essential features for any device that goes in a pocket.
I love the application idea but it'll only be possible on jailbroken phones because Apple doesn't allow direct access to the system preferences (the entire SCPreferences etc. is undocumented by Apple) and I expect that trying to accessing them would get your app. booted from the App Store.
it's not user friendly, and from what I know it's impossible to have applications working in the background so the app would be useless.
i can't imagine what would happen if Nokia expected every user out there to swtich states on their own! Fail, that what would happen. It's not a laptop...it shouldn't behave like one.
N95 had also some battery problems and were fixed with a later update. If there are indeed any problems, Probably Apple will fix them too.
