Quick Charge 1.0 was unveiled way past release. Yes, when it was unveiled, many devices already had it. It allowed modern Snapdragon S4 devices to charge faster than older devices. Not long after, Qualcomm announces Quick Charge 2.0. Luckily, this one hasn’t been released yet so you aren’t missing out (yet).
Quick Charge 2.0 will be available on all Snapdragon 8800 powered devices. Even the newly announced but unreleased HTC One “only” runs a Snapdragon 600 processor, so these 800 models won’t be coming out for a while. But when they do, the devices will charge up to 75% faster than a device without Quick Charge. That sounds like a very impressive number, and if it goes as they say it will, it’ll benefit a lot of people.
For Quick Charge 2.0 to work, you’ll need a compliant charger though. We’re curious if this is truly a chipset feature or just a device that supports a bigger current draw (like the Note II taking 2 amps instead of the standard 1). It seems that Quick Charge 2.0 chargers provide up to 60 watts. Since watts = amps x volts, it seems that it just relies on a more powerful charger and a USB port that supports a higher current. A Note II charger does 5V and 2A, so that’s 10 watts. 60 watts will just raise one or both of those factors. We’ll see how that affects battery health, as the faster you charge a battery, the worse it is for it.
