If there's one thing I think we can all agree on, it's that when our phones are low on juice, we're willing to jump through a hoop or two to power back up. Be it an awkwardly placed public wall outlet, regularly carrying around external chargers, or buying a phone with a user-replaceable battery so that swapping in a spare is quick and easy.
We also all know somewhat instinctively that using our phones while they're on a charger will decrease the rate at which they charge - that's just common sense. Even if the phone is charging, using the device obviously consumes power, and that cancels out some of the net effect charging has. Read More
When it comes to fancy ways to charge your fancy smartphone, the latest devices generally have two tricks up their sleeve: wireless charging and quick charging. The people behind the Qi wireless charging standard are hoping to have the best of both worlds. Today the Wireless Power Consortium (which includes members like Texas Instruments, Huawei, Nokia, Philips, and Logitech) announced that the latest version of the specification will support charging at a rate of up to 15 watts.
That's a very specific number, and if it sounds familiar, it should: 15 watts is the most common maximum input for the new quick charging standards in their various copyrighted incarnations, from Qualcomm, Samsung, ASUS, et cetera. Read More
Smartphones that charge slowly suck. And in a world where battery capacities are getting larger by the month, long charge times could become a legitimate gripe. But Qualcomm has apparently been on the case for quite a while now, quietly implementing a technology it calls Quick Charge 1.0 into some of its Snapdragon chipsets.
Quick Charge is actually a physical circuit built into the chipset that interfaces with the USB connector, so this isn't some kind of firmware voodoo. Qualcomm acquired the tech when it bought Summit Microelectronics last June.
Qualcomm claims QuickCharge allows you to charge your smartphone up to 40% faster than one without Quick Charge. Read More
