I really don't understand his battery life claims. Either he doesn't use his phone much, or he charges it when ever he can.
A true revolation would be a phone that could last days without needing a charge. To my mind it's one of the great features of the iPads, you can leave it on playing video for literally 10 hours, it lasts days with average use.
For all the improvements on processors, screens and cameras we get very little inovation in battery technology and it's stifling the industry.
Here's where Apple's resistance to larger screens (and bigger smartphones) also bites them: Larger phones can pack much larger batteries, leading to longer battery life (even despite the larger display, which does _not_ consume proportionally more energy). E.g. a Note II will last nearly two full days without a recharge, and you can get 2.5 days of normal use with power savings enabled.
My own experience with Galaxy Mega (5.8) is awful. Its screen is huge; coming from an iPhone 4S yet its battery is terrible; barely last a day (7am til 6pm) with a full recharge.
I would agree to a certain extent. We still have phones that last days before needing a recharge, but they are not smart phones (remember those Nokia candy bar phones?)
However, with the growth of smart phones, it seems that companies are focusing on one-upping each other on specs other than battery life. Most launches have always worked hard to keep the battery life at roughly 8 hours, no more no less, and spend any excess juice on more features. I'm pretty sure that the reason for this is the assumption that people will charge their phones at least once a day anyways, which would be a perfectly fine assumption IF the phones actually DO last 8-10 hours on normal use... but sadly for me, most of these phones usually last 5 hours with the level of intensive use that I put my phone through everyday.
Apple and others could take advantage of the -30 percent or so battery life improvements the next-gen chips are offering them, but none of them do that, because they will cancel it out with all the performance they can squeeze out of it, while not breaking the consumption limit of the previous generation.
