is there any smartphone today that comes close to the iphone battery life time?
since i broke my samsung and went back to the iphone i notice how i can go 2 or some times 3 days before i need to charge it. with wlan activated most of the time, and using it regularly.
the samsung, after a full day the battery would be on 20-40% so i charged it every night to be sure i wouldn't run out.
BadaOS phones last longer than Iphones. High end droids tend to drain battery faster mainly because of their hardware (huge screens mostly). Complex OS' process management adds to that.
Mid-ends that have more similar hardware to the Iphone 4 should also last close to that (most of all thanks to smaller displays).
That also bothered me at the beginning.
Anyway peep gsmarena's battery tests:

It's a fresh section so their database only contains some of the newest phones but if there'll be anything good if it comes to battery life they should have it listed there.
Why do you think that is?
Past Nexus devices were expensive and.. not too popular for some reason. No one really expected them to sell here I think. So they shipped small numbers of those devices and that's also why their price was even higher.
There are similar devices that are cheaper and come with heavier marketing, so they sell instead.
Perhaps if Google pumped a lot of marketing money things would change but that's what they never do.
The Galaxy Nexus is expensive here. The Galaxy S2 costs about 1500zl and Galaxy Nexus costs about 2200zl. It's much more expensive than it's really worth.
