The iPhone-waiting populace sent up a ragged cheer when Apple last week revealed that the anticipated handset would feature longer battery life than had originally been announced. Eight hours of talk time is a figure that nearly doubles the nearest competition, and it seems like an astounding amount of juice in that small a device.
And so the questions began to rage: just how did Apple manage to eke all that time out of the battery? Battery-testing is somewhat of black art to begin with: results are idealized figures rather than real-world usage times. Until the iPhone is in the hands of the populace at large, we won’t know how the battery really performs. But until then, Slate’s Explainer column offers some good theories on how Jobs and co. stretched out the juice, laying it mainly at the door of better power management.
One other interesting tidbit plays into the mix, however: the new glass screen, announced at the same time as the extended battery life. According to Slate, glass transmits light more efficiently than plastic, meaning that it requires less power to keep the screen at the same brightness.
We’ve said it before, and we’ll most assuredly say it again: the success of the iPhone will come largely from its attention to detail.
As an apple stockholder, I am more concerned with ATT portion. High user rates and poor service, Cingular ranks low, can kill the whole deal. Buyers, who have high expectation, will not work well w/ ATTs tech support. They dont seem to know anything.
I've been with Cingular/AT&T since it was AT&T the first time. Customer Care is pretty crap with them. They ranked at the bottom in jdpower.com
I got side tracked with my original comment... lol
How does the iPhone cram so must juice? SIMPLE... Steve Jobs is a Jedi Knight and he uses his powers in mysterious ways. That or it's witch craft,... but I'm think it's my first guess! :D
