Apple took the curious step of not really increasing the battery life on the iPhone 5 despite the faster chipset with LTE connectivity... but it seems that the decision to wait a little while before bringing the 4G technology to the phone has allowed it to optimize the power pack.
However, it's not the stellar performance we've seen from other smartphones of late. It's not terrible but it won't be lasting beyond late evening on most days.
We don't see this as a real problem in reality, as the modern smartphone user should be ready to charge each night if they want to keep chugging along every day.
That said, during our tests we twice managed to run the battery down by mid afternoon through general testing: running turn-by-turn directions for 15 mins, watching a video, talking on the phone for 20 mins and messing about on the internet for a good hour or two.
In the more lackadaisical days, we found it was only getting to dangerous levels around 10PM - but we'll await the findings of our more scientific battery tests to see how well or poorly the phone performs in the power stakes.
4G is the new trick on offer from the iPhone 5, with Sprint, Verizon and AT&T offering high speed plans.
However, customers should be wary of the 4G service available in their areas. Verizon has the largest coverage in the U.S., followed by AT&T and then Sprint.
