How did Apple squeeze that extra life out of iPhone’s battery?

“Apple now says the iPhone’s battery is good for up to eight hours of talk time or 250 hours on standby. But what the company isn’t saying is how this has been achieved,” Stephen Withers reports for iTWire.

“We suspect that the battery capacity is unchanged from the January announcement, and that one of two things has happened,” Withers writes.

1. The only thing that’s changed is Apple’s estimate of how long a charge will last.
2. Fine-tuning of the iPhone’s power management and other characteristics.

Withers writes, “Or maybe Apple knew that pundits would find fault with the device (and battery life and the potential for scratched screens have been at or near the top of the list), so it initially left those issues open and sat back waiting to slap the inevitable criticisms down just before the ship date.”

  1. I can say that other devices are very susceptable to scratched screens. I have a BlackBerry Perl with a screen that scratched while tying to insert it in the holster . . Not impressed. It will be interesting to hear hwo many people try to start whinning about the first little blemish encountered on their new iPhones.

  2. .. or they let the competition think that battery life sucked until the very last moment. That must hurt.

    Exactly. Remember, the only reason they revealed the Phone AT ALL was because they had to (FCC)..

    Why tell the competition more than you need to… they should do this everytime.

  3. CHICAGO (June 19) – AT&T Inc. on Tuesday launched what it said is the first service letting callers share live video between cell phones.

    The new AT&T Video Share service won’t apply to the iPhone, which uses an older network.

  4. be interesting to look back after a couple months of iPhones in the wild. plastic scratches, yes…but Glass CRACKS! it’s gotta have an insanely rigid casing to keep America’s fat asses from cracking the screens when we sit down! wait and see…wait…and…see…

  5. Battery technology is not at a stand still. It is advancing just as are most other techs.

    Could it be possible that Apple has found a supplier of batteries that is making a product that is better now than it used to be? Gee, I wonder.

  6. Exactly. Remember, the only reason they revealed the Phone AT ALL was because they had to (FCC)..

    yeah that was “the excuse,” but certainly not the truth.. The six-month pre-announcement was all part of Apple’s plan to create the largest amount of hype possible.. Unlike most Apple products, the they really needed time to set this product up. In announcing six months early, they accomplished two major tasks.

    1. They’ve generated hysteria and hype of the largest proportions while creating the biggest CE product launch ever. Remember, if during Jobs iPhone announcement he had said “and it’s shipping now,” there would not have been half the media blitz that they’ve received.. Certainly people would not be camping out in front of Apple stores getting local news coverage.

    2. They’ve given adequate time for people locked into contracts with other carriers time for those contracts to expire.

    The FCC line was a good cover up though.

  7. >CHICAGO (June 19) – AT&T Inc. on Tuesday launched what it said is the first service letting callers share live video between cell phones.

    Is that for real? Europe’s had 3G video calls for the past 2-3 years. Why does the US lag behind the rest of the world so much when it comes to cell phones. Bizarre.

  8. TT – know that feeling, hated it. Learned to live on my remaining pittance and saved a bundle after my youngest graduated and It Was Over.
    On topic … I think it was a plot by S.J. and company. Maybe not from the start, at least from the first gasps of disbelief. Of pain. My phone may be able to last two days with only 5 hours of “life”, but I’ve worked with people who do that much by lunch! S.J. should have known better – and may well have.

  9. SJ knows about exposition, i.e. don’t tell the audience what they don’t need to know until they absolutely need to know it. Done well the storyteller can create tension, intrigue, supense, and lengthy lines outside Apple stores on Fridays at 6pm..

  10. Who cares?

    You can buy third party batteries for iPods that are significantly higher-capacity than the stock batteries. Apple probably decided to use a higher capacity battery once manufacturing started.

    That could have been changed months ago. Apple just decided to wait until an ideal time to make the announcement, after all the “critics” wasted their time saying the battery was weak (and the plastic surface was scratch prone).
