Intel joins A4WP, a newcomer to wireless power standards

Wireless charging isn't a very useful idea if every device needs a separate charging station, which is why it's notable that Intel has joined a newer consortium called the Alliance for Wireless Power

The chipmaker got itself a seat on A4WP's board of directors, joining Samsung, Qualcomm, Broadcom, Integrated Device Technology, and Gill Industries, the consortium said Wednesday in a statement (PDF).

Intel likes A4WP because the technology extends not just to mobile phones but also laptops. Here's how Navin Shenoy, vice president of Intel's PC client group and general manager of its mobile client … Read more

Samsung Galaxy S4 gets wireless charging help from accessories

Samsung is no stranger to peddling smartphone accessories that fit into its ever-expanding hardware portfolio. Meet the latest member of this family, the Samsung Wireless Charging Pad ($49.99).

Intended to play nicely with the company's Galaxy S4 flagship smartphone, the charging pad is actually compatible with all smartphones that use the prevalent Qi standard.

Unfortunately, your U.S. Galaxy S4 is about to prove codependent. That's because it doesn't have wireless charging built in, so to even use the charging pad, you're going to have to fork out for the charging cover, a $39.99 … Read more

Nokia's wireless chargers perk up local coffee shops

Last September, Nokia kicked off the launch of its Nokia Lumia 920 with promises of exposing more people to wireless charging -- an available, but underused capability -- by bringing it to spots where people go.

Specifically, Nokia said it would sponsor wireless charging stations using the Qi protocol at Virgin America airport lounges and Coffee Bean and Tea Leaf stores.

Earlier this week, I finally saw Nokia's power-promotion installed at my favorite Coffee Bean location on San Francisco's busy Market Street. What a sorry sight it was.

Market Street is a bustling downtown location, so I'm … Read more

Twitter launching music discovery app

CNET Update tweets to the beat:

Twitter is launching a new music service that will suggest songs to listen to based on accounts you follow or artists that are trending. As the world waits for the official launch, Ryan Seacrest seems to be enjoying it.

Android users can experience Chat Heads on the Facebook Messenger app, rather than download the Facebook Home interface.

Also in this tech roundup, I bring you the highlights from the DigitalFocus technology showcase, which includes the Honeywell Wi-Fi Smart Thermostat, the Linkase Wi-Fi signal booster for smartphones, the new Duracell Powermat iPhone 5 wireless charging … Read more

Apple patent envisions wireless charging on convertible laptop

Despite Apple CEO Tim Cook having knocked the idea of a convertible MacBook-iPad hybrid device, the company has filed a patent application for just that. The proposed patent, titled "Wireless display for electronic devices," was published by the U.S. Patent and Trademark Office today.

The application describes a computer display that is removable from its base -- basically a convertible laptop. But, what's different about this idea from other convertibles made by other companies is that it has wireless display technology. That means the device could be charged wirelessly.

Here's how Apple describes it in … Read more

Vertical wireless charging means cool things for your phone

The wireless charging stations of today are either small, flat surfaces upon which you position your phone, or laptop-size spaces that can fit more than one device.

You must lay your smartphone or tablet just so to see the full effects of the charge. A bump or slip makes charging less efficient, which means it will take longer to charge your phone cable-free.

The Alliance for Wireless Power (A4WP) is working on a next-generation wireless charging technology that can not only power smartphones and tablets laying directly on a charging pad, but can also throw its magnetic charging beam upward.… Read more

Wireless charging still has strings attached

As obviously useful as wireless charging is, it suffers from a Tower of Babel problem with incompatible standards and competing interests keeping it from truly going mainstream.

But the industry may yet be inching toward some level of sanity. AT&T is seeking from its handset vendors a commitment to one standard of wireless charging, CNET has learned.

The standard, known as PMA, or the Power Matters Alliance, is spearheaded by Powermat Technologies and Procter & Gamble, two unlikely leaders considering their highest-profile products are the bulky iPhone charging covers that only true power-hungry users submit themselves to using. … Read more

Galaxy S4: Cool features, awful launch

CNET Update didn't expect Samsung to be sexist:

Samsung finally unveiled its flagship smartphone, the Galaxy S4. But this was no ordinary press conference. The Galaxy S4 presentation was a campy Broadway-styled spectacle that was painful to watch with sexist caricatures of women.

Despite the distasteful event, the Galaxy S4 will surely be a big seller and top rival to the iPhone. Today's video offers a quick explanation of the smartphone's new features, such as being able to navigate by waving a hand over the screen. (Many of these features will also come to Galaxy S3 users.) … Read more

Samsung Galaxy S4 offers optional wireless charging

Good news, wire haters: the Samsung Galaxy S4 will support wireless charging.

The bad news? The feature will cost you upward of $100.

We're hearing that adding wireless charging to the S4 will require a new back cover ($39.99), as well as a dedicated wireless charger ($59.99). The charger is said to hit stores in April, but the back cover may not see the light of day until June.

We can't yet confirm if the charger supports the existing Qi standard (as Engadget reports), which would make it compatible with third-party chargers like the Energizer Dual Inductive Charger. … Read more

Apple eyes wireless charging via the iPad's Smart Cover

iPad owners may one day be able to wirelessly charge their tablets without the need for a separate charging station.

Published today by the U.S. Patent and Trademark Office, Apple's patent application called "Integrated Inductive Charging In Protective Cover" describes a method of using the iPad's Smart Cover itself as the wireless charger.

The cover would be built with inductive power coils and possibly a battery, both of which could provide juice to the iPad. Charging the tablet this way would be a simple matter of closing the cover, which would then power the iPad … Read more
