Qualcomm's Quick Charge technology extends to wireless power
Qualcomm's Quick Charge tech has been falling behind the times -- it's focused on wired power at a time when wireless is in vogue. The company knows it's time to change, though. It's introducing a version of Quick Charge for wireless power that aims to speed up your cable-free top-ups. Charging pads (with matching chargers) that meet Qualcomm's guidelines should not only deliver electricity quickly, but in a "consistent and safety-conscious" fashion. You shouldn't have to worry that a pad is overheating your phone, or that it's not living up to its performance claims.
Qualcomm's Quick Charge 4+ is both faster and cooler
We all want more power with less charging on our mobile phones. Qualcomm, the maker of the Snapdragon 835 processor, has long been working to provide lower power usage and faster battery charging. The current Quick Charge 4 technology, announced in November of last year, promises five hours of charge in five minutes, a 20 percent improvement in charging speed and 30 percent improvement in efficiency than the previous Quick Charge system. The company announced even more improved specs today: the Quick Charge 4+ system, which the company promises is up to three degrees cooler, up to 15 percent faster and 30 percent more efficient than Quick Charge 4. The first smartphone to use this new charging technology will be the Nubia Z17 from Chinese phone maker ZTE.
Google doesn't want proprietary fast charging in Android phones
Google isn't a fan of non-standard approaches to fast-charging Android phones over USB-C, and it's bent on having manufacturers fall in line. Its newest Android Compatibility Definition document (for Android Nougat) now says it's "strongly recommended" that device makers don't support proprietary charging technology that modifies voltages beyond standard levels, or otherwise creates "interoperability issues" with standard USB charging. In other words, tech like Qualcomm's Quick Charge 3.0 is likely considered naughty. On top of that, the company warns that later versions of Android might even require full interoperability with standard chargers.
Qualcomm says it's fine to fast-charge your phone over USB-C
Technically, USB-C and fast-charging methods like Qualcomm's Quick Charge 3.0 aren't supposed to mix. As Google's Benson Leung (a frequent crusader for good USB implementations) noted last fall, the USB-C spec explicitly forbids the variable voltage tricks that QC3.0 and others use to top up your battery in a hurry. Does that mean that your HTC 10 or LG G5 is at risk of catching fire, then? Not if you ask Qualcomm. It tells Android Central that you can make its fast-charge solution fit USB-C's voltage demands, and there have been "no reports" of problems so far. In short, you shouldn't have to worry when you plug in. So it's all settled, right?
Huawei can quick-charge your phone without hurting its battery
That fast-charging smartphone you just bought has a dirty secret: more likely than not, it's reducing the lifespan or capacity of the battery to get that breakneck speed. Huawei doesn't think you should have to compromise, though. It just showed off a lithium-ion battery whose graphite-coated anode (where current flows) allows for very quick charging without hurting either capacity or long-term longevity. How quick? With a 3,000mAh of the sort you'd find in a larger phone, Huawei can give you a 48 percent charge in just 5 minutes. Yes, you could have enough power for an evening out in the time it takes to change out of your work clothes. There's an even faster prototype that reaches 68 percent in 2 minutes, although its 600mAh capacity isn't practical at its size.
Qualcomm's Snapdragon 820 packs 600Mbps LTE and smarter charging
Qualcomm's Snapdragon 820 hype train is getting to be a bit much (just ship the thing, already!), but you might want to take notice of the latest news if you're big on data speeds -- or simply want to charge your phone in a hurry. The company has revealed that its future system-on-a-chip will include the first processor to support super-fast 600Mbps LTE-Advanced, blowing past the 450Mbps record from before. It'll upload at a brisk 150Mbps, too, and this chip is the first to support unlicensed LTE (aka LTE-U). Oh, and did we mention that it'll allow for multi-gigabit 802.11ad WiFi? You probably won't get to use much of this technology in the near term, but it's good to have a ton of futureproofing.
Quick Charge 2.0 is coming to USB charging stations
Isn't it annoying when some smartphones boast Quick Charge 2.0 but only come with a regular USB charger? Given the option, we'd rather spend the money on something more practical, like a multi-port USB charging station that supports Quick Charge. And yes, we managed to stumble upon one at Computex, courtesy of Hong Kong's Magic-Pro. The Power Station Super 4 comes with -- you guessed it -- four USB ports, two of which can automatically switch to either 9V or 12V for faster charging on compatible devices, while the third port offers the common 5V/2.4A output, and the last one does 5V/3A as the company anticipates a new wave of tablets that can take the higher current. Better yet, the hub comes with a car charger and a Quick Charge 2.0-friendly micro-USB data cable, so not bad at all for a $65 package. Expect this to hit the markets at around the end of this month.
Oppo Find 7 is the world's first phone that can take 50MP photos (video)
We've seen the teasers and we've seen the leaks, so it's about time to see the real thing. Oppo has finally unveiled the Find 7 in Beijing just now, and as promised, this Android 4.3 device really can take 50-megapixel photos! But as with many things in life, there's a catch here: the sensor is actually a 13-megapixel Sony IMX214 CMOS, so it's a software trick. Still, the results we saw earlier were surprisingly good, so read on to check out how it's done and what the rest of the phone is like.
Qualcomm grows Snapdragon 200 family with six new chips, targets emerging markets
Just because Qualcomm's gone to plaid (aka. reached ludicrous speed) with its Snapdragon 800 flagship doesn't mean the company's been standing still at the other end of the market. The Snapdragon 200 family just received a major boost with the introduction of six new chips geared at China and other emerging markets. Available with dual- and quad-core CPUs, the processors are manufactured using a 28nm process and incorporate HSPA+ (21Mbps) and TD-SCDMA radios. The new SoCs are optimized to provide good multimedia performance and long battery life, with support for dual cameras (up to 8MP rear and 5MP front), multiple SIMs (dual standby, dual active and tri standby), iZat location tech and Quick Charge 1.0. Qualcomm's Adreno 302 GPU rounds up the spec list, making these chips well suited for devices running Android, Windows Phone and Firefox OS. The company's expected to begin shipping these new processors (8x10 and 8x12) in late 2013. Full PR after the break.
Qualcomm details Quick Charge 2.0 and Snapdragon Voice Activation: 75 percent faster charging, wake by speaking
Qualcomm didn't show all its cards for this year when it unveiled the Snapdragon 600 and 800 at CES. The company is introducing a second-generation power charging technology, Quick Charge 2.0, that promises to cut mobile device charging times by as much as 75 percent versus regular power systems. Qualcomm has seen a tablet's 7-hour top-up time reduced to under 3 hours. While 2.0 requires an optimized charger and is baked into the Snapdragon 800, it's not exclusive to Qualcomm-based hardware -- or small devices, for that matter. The updated Quick Charge is available as a stand-alone circuit, and could drive even laptops demanding up to 60W of energy. We don't yet know the customer list, although Snapdragon 800 partners are included as a matter of course. The telecom giant is saving one trick for itself, however. Snapdragon Voice Activation lets Snapdragon 800-based devices wake up through a specific voice command, whether or not those devices are online: think of it as a more advanced, less search-dependent parallel to Samsung's wake-up trigger in S Voice. Both devices and software support must fall into place to make Voice Activation work, but truly hands-free mobile control could have a solid footing in the market before the year is over.
Nissan downsizes EV quick charger, slashes price while eying US, EU and Japanese markets
Like a hamburger Happy Meal, Nissan's brand new quick-charge station is fast, cheap and easy, thanks to its tasty new electric circuit technology. Nissan claims the 49kW charger takes up less space, is easier to install and a heckuva lot cheaper than former models, leaving only a ¥1 million yen (or around $10,000) dent in your pocket compared to the former ¥1.47 million (or $19,088) crater. Hoping to sell around 5,000 units and set up charging stations throughout the Land of the Rising Sun by March 2016, Nissan sees the technology rolling out in the US and Europe sometime in the near future -- no toy included. Pull over for the full PR after the break.
Nissan to give Leaf faster charger in 2012: home charging goes from glacial to a snail's pace?
Though well on its way to joining the Dodo, one of the internal combustion engine's advantages over its plug-in competition is refuel time -- it only takes a few minutes to gas up, but you're talking hours for an EV to top off its batteries via a standard 220 / 240-volt socket. This fact is not lost on Nissan, as it just revealed plans to offer a higher-rate charger in its 2012 Leaf -- the current model's 3.3kW charger needs eight hours to power up -- in order to better compete with the Ford Focus Electric's three to four hour charge time courtesy of its 6.6kW unit. And all you early adopters won't be "orphaned," as 2011 model Leafs can be retrofitted with the new electrics -- no word if Daddy Warbucks will be footing the bill.
Ford Focus Electric unlikely to support DC quick-charging, slower than the Leaf after all?
At its unveiling at CES, Ford missed no opportunity to talk up the ability of its Focus Electric to charge in half the time of the Nissan Leaf when connected to a Level 2 (220 - 240V) charger, of the sort that Best Buy will gladly install for you for just $1,499. Three to four hours is all it should take, indeed impressive compared to the eight hours the Leaf needs at the same voltage. However, the story doesn't end there, as the Leaf has another trick up its sleeve: DC fast-charging via the CHAdeMO standard. That gives 80 miles of range in just 30 minutes and, while not a global standard yet, it's certainly trying to be. The SAE is working on its own DC quick-charger standard, and that's the pony Ford is looking to back, saying: Fast charge will not be included on the Focus Electric until an industry standard has been set by SAE. Once an approved/accepted standard is in place, we will work on getting the car ready for [it]. That leaves us with two questions. First, will the SAE get its standard finalized before Ford gets the Focus Electric finalized? Second, will the SAE standard be compatible with the Japanese CHAdeMO standard? Sadly, our magic eight ball is not giving us much hope on either account.
Toshiba's Super Charge Ion Battery gets 90% full in 10 minutes
Imagine this -- you, sitting in a dingy airport terminal waiting on your flight with a lifeless laptop and just 10 minutes to spare. You've got oodles of spreadsheet work to do before 8:00AM tomorrow, and unless you get it done on this flight, you're fubared. Toshiba is looking to make said scenario seem like one that's not so grim, as its prototype SCIB (Super Charge Ion Battery) purportedly has the potential to get 90% full in just 10 minutes. The battery was unveiled at CEATEC 2008 in Japan, though little was known about its eventual availability. Shame development cycles can't be fast tracked in a similar manner, huh?[Via UberReview]
Quick Charge kit debuts at $29.99
Just a quick heads up: that Quick Charge kit that Joystiq took a look at earlier this month is available now for the not altogether horrible price of 30 septim...err, dollars. Unfortunately for them, I've already managed to free myself "from the tyranny and mess of cables" by picking up a couple rechargeable AAs and a wall-charger. Anyone have an ache that only the Quick Charge kit can soothe?
