Is iPhone Battery Usefulness On the Decline?
jfruh writes "Every time a company rolls out a new version of a product, it extols how much better it is than the previous version. Thus, Apple spent a part of its iPhone 5 rollout touting the staying power of the latest version of its battery. But have iPhone batteries really seen improvement since the original came out in '07? Kevin Purdy crunches the numbers and concludes that, while the 5's battery beats the 4S's, we still haven't returned to the capabilities of the original phone."
And as competitive as smartphones are today that's close to as good as we'll get for a bit. There IS a type of Lithium-ion battery that can store twice the charge of today's batteries at the same volume, but that's apparently coming to electric cars first; which obviously spend a lot more on batteries per unit and are in far more need of it.
But expect these batteries in phones at some point. In the further future the most promising technology is lithium-air batteries, which offer up to 10x the current charge per volume as today. But there are still numerous problems with them, and so an ETA there would be indefinite but quite possibly less than a decade. Still, imagine a phone that would need charging less than once a week!
The iPhone 5 is crap compared to the new iPhone 6 that will come out next spring.
Humorous.
And yet in that comment lies a revelation of why Apple's supposedly boring updates are not a problem.
Because from the 4 to the 4s, it was not that much of a leap. Or so it seemed at the time.
But now from the 4 to the 5, that is actually a pretty big jump. So even though we might see something like a 5s next year, you can be pretty sure that waiting for that will not be an amazing leap over the 5 - so there's little point to wait. And yet when the 6 does come out a year or two from now, it will probably be a really impressive gain over the iPhone 5.

Apple isn't doing anything differently in this regard than any other phone manufacturer.
They use the highest density most expensive option. A few years ago this cost quite a bit more and fewer companies used them.
However, as a consumer, i'd rather a design concept like the motorola razr maxx, prepared to have a bit more thickness if it means the phone will last a weekend without charging.
I understand. I own the MacBook Pro Retina which made huge sacrifices for thin and light. People really like thin and light when they see it, when they try it. But just like the move from desktops to laptops, thin and light likely means 30% less device for 30% more money.
