Yesterday it announced that its new software will add an hour of battery life during normal usage.

It will also have a new power-saving mode that will give people an extra three hours of battery when their phone is running low on juice.

Ideally, Apple would announce that it added an additional 12 hours of battery life, but that's probably impossible.

So, we'll have to take what we can get.
