Qualcomm's latest flagship chipset, the Snapdragon 835, is the first to come with Quick Charge 4.0, which is said to give you around 50% battery in just 15 minutes. However, now that the Snapdragon 835 is out and available in a handful of smartphones, Quick Charge 4.0 is nowhere to be found. Well according to PCWorld, Qualcomm states that Quick Charge 4.0 will be more widely available around the middle of this year. As is usually the case for Qualcomm, they didn't name-drop any of their partners, but we do know that most of the major players in the smartphone world are working on Snapdragon 835-powered devices.
The Galaxy S8 and Galaxy S8 Plus - which were the first devices to launch with the Snapdragon 835 - launched without Quick Charge 4.0 support. In fact, they don't even support Quick Charge 3.0, like their predecessors. This is likely due to the fact that Exynos versions of these smartphones use Adaptive Fast Charge, which is on pace with Quick Charge 2.0, so they wanted the experience to be the same across the board (this is not confirmed, just speculation). But there are a couple of other devices with the Snapdragon 835, like the Sony Xperia XZ Premium and the Xiaomi Mi 6. Neither of which support the latest version of Quick Charge, but do support Quick Charge 4.0.
Currently, it's unclear why the current crop of Snapdragon 835 devices out there do not support Quick Charge 4.0, but it is at least refreshing to know that there will be Quick Charge 4.0-compatible smartphones coming rather soon. With many manufacturers having yet to announce their flagships with the Snapdragon 835, it's possible that we could see an influx of flagship smartphones over the summer. Something that doesn't normally happen. Most major launches are in the spring and the fall, but due to the Galaxy S8's Snapdragon 835 exclusivity, and it launching later in the year, it appears that has changed the schedule at least for 2017. Quick Charge 4.0 isn't yet available in any after-market chargers from the likes of Tronsmart, Anker or AUKEY, who have put out many Quick Charge 3.0 (and Quick Charge 2.0, 1.0) accessories. Those should be coming out soon as well, once Quick Charge 4.0 devices are on the market, or at least announced.
