iPhone 2.2 Updates Best Easter Egg? Improved Battery Performance

Apple released the new iPhone OS, Version 2.2 on Friday, so if you have not done so already please open iTunes and update your iPhone,

New Features that Apple is touting,

Google Street View for Maps, see where you are going before you get there.
Podcast downloads over WiFi or 3G
Updated Safari, the iPhones web browser so that you always see Google search.

One of the things we have noticed and have seen mentioned across the blogisphere is much improved battery life. We use our iPhones more like a Laptop, checking mail, feeds in Google reader and what not. Saturday we went Geocaching with our iPhones, and normally this would have sucked the battery dry in the hours we were out caching. But Sat, after we got home both of our iPhones were still half full.

Nice work Apple, while Cut & Paste would have been a nice addition, this kind of improved battery performance should have been noted on the top of the list of reasons to upgrade to 2.2.

Have you noticed better battery life after your upgrade?
