If you noticed that your new phone was charging faster than your old one, that’s probably due to QuickCharge 1.0, a relatively new technology available on over 70 phones, including the HTC EVO 4G LTE. Qualcomm posted about this on its blog earlier today, unveiling the technology and hinting that it was already widespread.
Unfortunately Qualcomm didn’t say much, other than the technology exists, and that requires 40% less time to charge. The company made generalizations about a generic phone charging scenario, with no details given on what that phone, battery capacity, or charger might potentially be. For all we know, the new charging technology could be the same general concept as the FastCharge Force AC Toggle Widget.
The blog entry really could be read as, “Do you notice your phone charging faster? Yes, that’s our technology. No? Give it a bit; it’s not on your phone yet, but it could be!” It also does not mention if this is available via a firmware update, or if it’s already shipped – just that the capacity exists on these phones. I mentally envision a snake-oil salesman when I’m imagining that quote, stroking his goatee, but I doubt Qualcomm is all that interested in deceiving us.
I don’t particularly notice that my 2000mAh HTC EVO 4G LTE (listed as one of the supported phones) charges any faster than my EVO 3D with a 4000mAh battery does (assuming the 4000mAh should take twice as long), so chances are the technology is coming, or I’m not sitting there with a stopwatch waiting for the charging light to blink out.
It will be interesting to see if Qualcomm details exactly what it is, where it is, when it is coming, or when it was implemented. As it stands, its 40% QuickCharge claim sounds a lot like the SBC kernel charging claims from the early days of the original EVO 4G kernel development to me.
