Photos leak of purported next-gen iPhone’s thinner, higher capacity battery

“As the launch of the next iPhone approaches, lots of parts have been leaking out and we’ve been able to put the pieces together almost like a reverse iFixit teardown,” Mark Gurman reports for 9to5Mac. “Over the course of the past couple of weeks, we’ve seen internal components and LCD parts making their way into the hands of iOS device parts suppliers. The most notable part leaks this year were the back plates of the new iPhone. We posted the first photos of these in May. Those new parts revealed an all-new thinner enclosure, metal design, smaller dock connector, and various other next-generation iPhone attributes.”

Gurman reports, “Today, a reliable parts source sent us images of new iPhone battery packs that they received. Notably, these new battery packs sport a higher capacity than the packs in previous generations of Apple’s smartphone. This new battery features a capacity of 1440 mAh. That is up from the capacity of 1430 mAh on the iPhone 4S and up from 1420 mAh on the iPhone 4, according to iPhone repair shop iFixYouri, whom examined the battery photos. Along with the increase in battery capacity, the new battery also features a new voltage of 3.8. This is up slightly from 3.7 on both the iPhone 4S and iPhone 4.”

  1. Does the 0.1V increase in voltage mean that they are using a different battery technology ?

    Batteries are made from a number of cells and as you can’t have part of a cell, the available voltages have to be integer multiples of the individual cell voltage.

    1. All batteries have internal resistance. There is voltage (and energy) loss in that for every battery. That’s why few batteries give the output voltage that matches that you’d calculate from the electromotive tables. Maybe Apple (or Apple’s supplier) has found a way to waste less energy in the battery itself with the interesting side effect of a slightly higher output voltage.

      I’m not saying that this rumor is any more real than any other rumor, but it does have a possible explanation for part of it.

    2. Hard to tell. If this is a spec for voltage under load it might mean they’ve reduced internal resistance through some sort of design change even if they use the same chemistry. Overall, this is nice but not dramatic.

  2. I support the move to a smaller dock connector (just wish it had been introduced sooner with the New iPad), however, I would prefer that Apple keep the iPhone the same thickness and increase battery capacity by a substantial margin.

  3. Is the battery have new dimensions or is it the same dimensions as the iPhone 4 and 4S batteries? If so, it may be a redesign for the old phones. One would expect a longer dimension to the battery with the new form factor to the phone to accommodate a more significant increase in capacity. Does the increase in length offset the possible reduction in diameter to the battery and as a result not have a large increase in capacity? This would have been useful information to include in the article.
