Tesla CEO Elon Musk and iPhone Engineer discuss battery technology [Video]

There’s no real hard news at this talk given by Elon Musk this week but it is certainly interesting to see the back and forth with the iPhone Engineer (Evan Wong? Didn’t quite get the name) and the CEO of Tesla. Apple is of course rumored to be an investor in Tesla’s battery Gigafactory so that makes the conversation all that more interesting. Some notes:

  • The engineer manages a big part of the hardware development of the iPhone.
  • Apple is one of the biggest buyers of batteries along with Tesla and they’ve done a lot of thorough testing
  • Chemistry, material, packaging and process affect  battery life constant.
  • Tesla buys 18650 form factor batteries and is sticking to them.
  • When musk asks about the energy density, the engineer knows not to say anything (he says he doesn’t want to get sued by his employer – to many laughs from the audience).
  • Musk assumes the battery energy density is public domain because of teardowns
  • Musk says in high production they can get to 260Wh/KG at the lowest price per kW which might be good info for those looking at the Gigafactory specs.
  • Apple likely can’t use these cells in their products because they are 18mm thick, much thicker than many of Apple’s products – or so speculates Musk

iPad Air teardown: never mind the repairability, feel the tech

all

iFixit has done its usual trick of hopping over to Australia to get its hands on an iPad Air in the first time-zone to open its doors for business to bring us a look at the innards of the new device. The device is now on sale in the U.S. too, with supplies expected to be good.

No surprise that the company found little prospect of success for DIY repair, reporting that even opening the casing was a challenge: when you pack that much technology into so small a space, there’s going to be a lot of glue involved.

iPhone 5s battery capacity 10 percent up on iPhone 5, 5c up 5 percent

5battery_678x452

AnandTech dug into the FCC filings for the new iPhones to reveal that the iPhone 5s battery offers approximately 10 percent more capacity than its predecessor, while the 5c battery offers a more modest 5 percent gain. That’s a different size battery (5.96Wh vs 5.92Wh) than we’d seen in supposed 5s prototypes …  Read more

Mophie joins colorful iPhone trend with Spectrum Collection battery-cases

1350x1240_wysiwyg-helium-ip5-hero

With a gold iPhone 5S and multi-colored iPhone 5C expected on September 10th, Mophie has responded by offering a choice of five different colors for the Juice Pack Helium external battery-case for the iPhone 5/5S which we reviewed back in March.

[We] today announced five distinctive new colors for the juice pack helium: blue, purple, pink, green and red. The new matte-finish, jewel-tone cases wrap serious protection and power in a burst of color, delivering 80 percent more battery life and edge-to-edge protection against the drops, bumps and scratches of everyday mobile device use.

The units are otherwise identical to the standard Juice Pack Helium, with a 1500mAh battery that we found delivered on Mophie’s claim of between 6-7 hours additional usage.

You can pick up Mophie Helium Juicepacks at Amazon starting at $68 or on Mophie.com for $79.99 retail price. Read more

Sharp announces first IGZO 7-inch tablet, claims battery life increased over 2X with new tech rumored for Apple’s mini iPad

We heard reports in the past that Apple passed on Sharp’s IGZO display tech for the third-generation iPad due to Sharp not having the tech ready in time. Going with Sharp’s IGZO tech would have allowed for a thinner display assembly, a brighter display with less LEDs, and the ability to use a smaller battery or extend battery life specs as a result. It could have also helped shave off some of the increased weight and depth of the new iPad. These are all things we witnessed first hand when we got up close and personal with a few IGZO demos at IFA this year.  Sharp is announcing today its first 7-inch tablet to use the display technology, claiming the 1,280-by-800 IGZO display allows for 2.5 times the battery life from the tablet’s 2,040mAh battery (via ComputerWorld).

With the iPad mini launch coming later this month, it is a possibility the tech is finally ready for Apple to take advantage. Sharp also has 10-inch and 13-inch variants of the IGZO displays, but the 7-inch would of course make a lot of sense for iPad mini given what we already know about the device. Apple’s ability to increase battery life, or simply have the ability to use a smaller battery (in a smaller form factor) while maintaining battery life specs, is just one benefit. Another big benefit for Apple would be narrow borders: rumor has it—which is something we also talked about a lot in the past—the iPad mini will have a much narrower border than previous-generation iPads. Sharp told us its IGZO LCDs can be built with a bezel under 2mm, and it was showing off a demo display with a 1.75mm border at IFA. That would definitely fit the bill for the narrow-border, one-handed experience we expect from iPad mini. Read more

Consumer Reports: Forget what we said before, new iPad is the best we’ve ever seen

Consumer Reports took a beating for measuring the new iPad’s heat and charging non-issues under intense loads. However, it still overwhelmingly recommended Apple’s new device.

The high-resolution screen of the new iPad establishes a new benchmark in excellence, providing the best rendering of detail and color accuracy we’ve ever seen on a tablet display. As a result, the iPad tops our new tablet Ratings, posted today.

Performance on the new iPad ($500 to $830) was superb in virtually every other way as well. The 5-megapixel camera took very good photos. Verizon’s 4G network yielded very fast, dependable connectivity to a 4G-compatible version of the iPad in our informal tests. And despite the energy-intensive display and graphics, the iPad still has longer battery life than all other tablets.

Responding to consumer comments on the new device, and to coverage from other reviewers, we also carried out further tests that confirmed the new iPad is warmer in its hottest spots than the iPad 2. But we didn’t find those temperatures to be cause for concern. In addition, further tests of observations we made that the new iPad was not recharging when playing a demanding, intense video game, showed that the problem was limited to times when the device was playing a demanding game with the screen fully bright. Our high overall judgment of the new iPad was not affected by the results of either battery of tests.

The biggest downfall? Read more
