Quick Charge for Android
Chipset-maker Quallcom in 2012 announced Quick Charge 2.0, the second iteration of its technology that lets you get more juice into your smartphone in a shorter amount of time. The short version is that there's a controller in the power supply — whether it's plugged into a wall or a car outlet — that talks to the phone and regulates the increased flow of life-giving electricity, without letting things go overboard.
Once you use it, you'll never want to go back.
There is a side-effect to this increased charging speed. And that, of course, is heat. You'll feel your phone or tablet get a little warmer than you're probably used to. Qualcomm says that's OK, it's expected, and that any adverse effects the battery suffers because of it are negated by the fact that you'll most likely get a new phone before noticing any reduced performance.
We've already got a number of devices released in 2014 that support Qualcomm's Quick Charge standard, and more are being released in 2015.
