How about 50% more? That would change things a bit. A phone that doesn't last all day is a bit of a joke - however, it seems to be the standard now.
The iPhone 1 would easily last 2 days. Even the 4 - using iOS 4 - would last 2 days for me, and 1 day under heavy use. The 5 barely squeaks by until the evening and if I dare use it more than just a little bit, it dies long before the sun sets. Ridiculous. I believe most of this is due to changes to iOS - iOS now has WAY more stuff running in the background; even normal apps run in the background for up to 10 minutes after they're backgrounded.
As an app developer, I can very easily create an app that totally kills all battery life (I have done that by accident). That's wrong - the OS should take care of shutting down BG apps, and it also needs to be more efficient in handling the various things happening in the background. iOS is set up from the get go to be very good about battery life - just iOS 6 and 7 don't make use of that....
