CHART OF THE DAY: The Depressing Truth About Battery Technology

Source: http://www.businessinsider.com/chart-of-the-day-the-depressing-truth-about-battery-technology-2013-7

Here’s an old chart that sadly still holds true today.

While computing power has taken off, battery life has languished.

Christopher Mims republished the chart today at Quartz. It came from a 2005 report by Joseph A. Paradiso of MIT.

Mims asked if there was an update to the chart. He was told there was no update. In other words, battery technology is still stuck.

3D cameras, half the energy draw

Intel roadmap leak outlines Bay Trailbased Atom for tablets in detail 3D cameras, half the energy draw

Intel isn’t having much success keeping its upcoming Bay Trail-era Atom platform under wraps. If the previous overview leak wasn’t enough, a roadmap uncovered by Mobile Geeks has just explored the finer points of the tablet-oriented Bay View-T and its Valleyview-T processors. The most surprising leap may be in graphics: while we knew the GPU core would be much faster, we’re now seeing that the new Intel hardware can output to as much as a 2,560 x 1,600 display and record stereoscopic, 1080p 3D video in the event that 3D-capable tablets come back into vogue. Likewise, battery life should be rosier than you’d expect; Bay Trail-T can reach the same performance at half the power, which should lead to about two extra hours of video playback for at least some of the 1.6GHz to 2.1GHz processors in the lineup. Don’t get too excited by the potential, however. If the leak is accurate, Bay Trail for tablets isn’t expected until early 2014, by which point 22-nanometer Atoms will be a step behind the cutting edge.

Verizon LTE iPads Will Have Free TetheringLTE data on the new iPad can get expensive, but at least Verizon’s cutting you a break and including tethering in the price of your iPad data plan. Otherwise, it would be a $20 charge for tethering, along with an extra 2GB of data.

We’ve reached out to AT&T to see if it’ll include tethering gratis, but right now it seems like it’s not going to happen. Which, when combined with the $15 for 250MB lowest-tier plan compared to the $20 for 1GB, that looks a little bleak, but you do get an extra GB at the $30 tier. So AT&T still makes sense if you only want ~3GB of data and don’t care about tethering.

I’d just point out, though, that if you’re looking for an LTE hotspot option, it might make more sense to just get an LTE MiFi and use that for your phone, tablet, and laptop. That way you don’t have to lug out the tablet if you need mobile internet on your laptop or phone. The battery life isn’t as good as an iPad, but it was good enough to keep Gizmodo running at CES this year. Just something to think about! [GottaBeMobile]

Update: Here’s AT&T’s official comment: “We are working with Apple to enable this feature in the future, but we currently do not offer it.”

Ads will possess your phone using subliminal sound waves

Source: http://www.engadget.com/2011/12/09/ads-will-possess-your-phone-using-subliminal-sound-waves/

Er, we don’t want to sensationalize this or anything, but your phone could soon be at the mercy of inaudible sound pulses that trigger location-specific ads, sales promotions and other potentially demonic notifications. Unlike normal advertising within apps, and also different to sound-responsive apps like Shazam and Shopkick, a new platform called Sonic Notify is meant to work discretely in the background, without the need for any user activation. Its creators, NY-based digital agency Densebrain, plan to attach small high-frequency sound-emitting beacons to store shelves, which will “set people’s phones off” when they stand in front of a particular product. It’s not clear how the platform might affect your battery life, or why you wouldn’t just disable it at the first inopportune alert, but drug stores, TV networks and big players like Proctor & Gamble are nevertheless said to be gripped by the concept.

Carrier IQ Admits Holding ‘Treasure Trove’ of Consumer Data, But No Keystrokes

Source: http://www.wired.com/threatlevel/2011/12/carrier-iq-data-vacuum/

MOUNTAIN VIEW, California — An embattled phone-monitoring software maker said Friday that its wares, secretly installed on some 150 million phones, have the capacity to log web usage, and to chronicle where and when and to what numbers calls and text messages were sent and received. The Carrier IQ executives, speaking at their nondescript headquarters in a residential neighborhood in the heart of Silicon Valley, told Wired that the data they vacuum to their servers from handsets is vast — as the software also monitors apps deployment, battery life, phone CPU output and data and cell-site connectivity. But, they said, they are not logging every keystroke as a prominent critic claimed.

How You Can Get a Fresh iPad for $100 (Updated) [Apple]

Source: http://gizmodo.com/5848784/how-can-you-get-a-fresh-ipad-for-100

How You Can Get a Fresh iPad for $100 (Updated)I love my iPad. It’s the original model, bought on April 3, 2010. It’s been working perfectly since then but the battery life was really bad, lasting only a couple of hours lately. It was exhausted. I had to replace it.

In the process, I got a fresh iPad 64GB at the Apple Store for just $100. The good news, you can get one too.

After so many charging cycles, my original iPad’s battery was exhausted. It took forever to recharge and only a few hours to completely run out. I remember the days when I first got it. I could use it normally for a couple of days, watching at least two Netflix movies on it or browsing the web, running some apps and reading comic books.

I went to the Apple Store to ask for a battery replacement. But, as it turns out, you can’t replace an iPad’s battery. As the guy at the Apple Store’s Genius Bar told me: “See? They don’t have screws. We can’t replace the battery.”

Then he added: “If you want a new battery, we have to give you an entire new iPad.”

How? My iPad was out of warranty. I didn’t buy Apple Care. Furthermore, the iPad itself was broken on one side. One day I dropped it on the floor and the aluminum got quite chipped on one side.

He answered that this was no problem. I only have to pay $100 for the “battery.” In return, they would give you a reconditioned iPad with the same storage size as yours, with a fresh battery inside.

So I did exactly that. I paid the hundred bucks and got back home with a perfect battery life and an iPad with no blemishes whatsoever. If your battery life is sketchy—which is probably the case if you bought it back in April 2010—you should go to an Apple store, pay your hundred and get a fresh new iPad on your hands.

And your old iPad doesn’t go to waste. These get refurbished too. Any bad parts get replaced and go back into the cycle of Apple life.

Update: A former Genius shares his tips in the comments:

• You can do the same thing with any iPhone for $79, and most iPods for $69.

• Apple will replace an iPhone in almost any condition (the only exception being for devices that are literally broken into little pieces, or ones that are missing parts) for $199, even if it’s liquid damaged or cracked.

• Apple will replace any OOW damaged iPad for around half the price.

• On an iPhone 4, if the back glass is cracked, an Apple employee can replace it for $29 in only about 5 minutes, also not a bad idea if your camera lens is scratched beyond repair

• If you restore your device before bringing it in, there are no usage records saved and they have to take your word for it that the battery is defective.

That’s pretty good customer service indeed.
