Qualcomm’s QCC5100 Bluetooth Chip Hones in On Power Efficiency

If you own a pair of Bluetooth headphones, there’s a pretty good chance you’ve had to put up with subpar battery life. But you might not have to for much longer. At the Consumer Electronics Show on Monday, Qualcomm announced the QCC5100, a low-power Bluetooth system-on-chip that’s designed to deliver best-in-class features without compromising on power efficiency.

The QCC5100 supports data transfers up to 2Mbps and a Bluetooth 5 dual-mode radio that lets you stream audio to multiple devices at once. There’s also proprietary technologies like Qualcomm’s TrueWireless Stereo which eliminates the need for wires between left and right earbuds, Qualcomm’s high-quality aptX HD audio codec, and enhanced Qualcomm cVc and Fluence active noise cancellation (ANC) technologies.

All the more impressive is the claim that the QCC5100 is up to 65 percent more efficient at handling voice calls and music streaming compared to previous single-chip Bluetooth audio solutions. Qualcomm says it’ll deliver up to 25 percent better battery life than “the most popular true wireless headset on the market today.”

“This breakthrough single-chip solution is designed to dramatically reduce power consumption and offers enhanced processing capabilities to help our customers build new life-enhancing, feature-rich devices,” said Anthony Murray, Senior Vice President and General Manager of Voice and Music at Qualcomm. “This will open new possibilities for extended-use hearable applications including virtual assistants, augmented hearing and enhanced listening.”

One of the Bluetooth chip’s other highlights is what Qualcomm calls “quad-core processing:” a dedicated dual-core 32-bit application processor running at 80Mhz, dual 120Mhz Kalimba digital signal processors (DSP), and “next generation” developer tools. Thanks to an application stack that’s designed to run multiple programs concurrently, the QCC5100 is able to switch between music playback, incoming voice calls, and voice assistant services “smoothly” and seamlessly.

Qualcomm hasn’t skimped on sound quality. The QCC5100’s aforementioned ANC uses three different techniques, feed-forward, feed-backward, and hybrid, to eliminate the need for a discrete ANC chip. It also has a built-in 2-channel 99dBA amplifier and 192kHz 24-bit I2S and SPDIF interfaces. On the voice assistant side, the chip combines local voice recognition algorithms running over Bluetooth with cloud services on mobile applications to improve quality and reduce latency.

If all goes according to plan, expect to start seeing the QCC5100 in earbuds soon.

Google Reportedly Paying Apple $9 Billion to Remain Default iOS Search Option

Image
It’s widely known that Google pays Apple a certain amount of money on a semi-regular basis to make sure that it remains the default search engine option on iOS devices. It has been said in the past that iOS devices equal about 50 percent of Google’s search revenue on mobile devices, so it’s imperative to the company to keep that spot on Apple’s devices. Before the end of 2017 it was reported that Apple was getting upwards of $3 billion from Google to secure that spot. But now, more than a year later from that report, it sounds like the company may be paying a lot more to Apple. Business Insider is reporting information shared by analyst Rod Hall that states Google is now paying $9 billion this year to retain its default situation on iOS devices. What’s more, Hall actually thinks that number will increase by next year, and Google could be paying Apple for those default rights to the tune of $12 billion. Hall also echoes those earlier reports, saying ““Apple is one of the biggest chann

How to Get iPhone XS Depth Effect Control On iPhone X, iPhone 8 Plus, and iPhone 7 Plus

Image
The iPhone XS and iPhone XR have a brand new feature. After you click a Portrait Mode photo, you can go into the Edit menu and change the intensity of the bokeh. Basically, you can change the background blur (make it softer or more pronounced) after you’ve already clicked the photo. Apple is touting this as one of the best new features in iPhone XS . But you can get it on iPhone X, iPhone 8 Plus and even the iPhone 7 Plus using a third party app. The new depth effect sensor in iPhone XS blurs photos different parts of the background at a different rate. So the effect you get is similar to that on DSLR. This is not the same as what phones like Pixel 2 do. Since the app in question requires depth data to work, it will not work on iPhones with a single camera at the rear like the iPhone 6, iPhone 7, or the iPhone 8. How to Edit Background Blur in Photos on iPhone X, iPhone 8 Plus, and iPhone 7 Plus The app in question is called Focos and we’re big fans of the app. The app made it to our b

Facebook Uses Your 2FA Phone Number for Targeted Advertising

Image
Being stalked from one website to another by persistent advertising is a real issue, but some companies, like Apple, have made strides to try and reduce its impact . But targeted advertising isn’t going anywhere anytime soon, especially if Facebook has any say in the matter. The company has recently confirmed that it does indeed go to some pretty great lengths to provide information to advertisers, with this latest effort definitely one of the social networking giant’s worst. A couple of days ago, Gizmodo ran a piece that outlined how Facebook uses the phone number some users added to take advantage of two factor authentication as a way to target those same individuals with ads. This is an extension of how Facebook already handles phone numbers saved to the platform’s profiles. How it works normally is if you add your phone number to your Facebook profile, and then add your phone number to some online retailer’s online presence, those two sources can match and be used to target advert
