Sony recently unveiled its all-new Xperia X series smartphones at the Mobile World Congress in Barcelona. The Xperia X Performance, the Xperia X and the Xperia XA are all 5-inchers, which is a departure from the current trend of phablets that most companies seem to be concentrating on, given the increasing popularity of large screened handsets in most regions around the world. While the Xperia X Performance is powered by the Snapdragon 820 SoC from Qualcomm, the Xperia X has the comparatively more humble Snapdragon 650 running under its hood. The third device, the Xperia XA, runs on a MediaTek chipset (Helio P10 MT6755).
Coming to the two Snapdragon chips in question, both of them support Quick Charge 3.0, but a recent post on Qualcomm's official website seems to suggest that neither of the two handsets will actually support the latest technology, but will only come with support for Quick Charge 2.0. The post outlines some of the features of the two Sony smartphones that run on Qualcomm's latest SoCs and highlights the benefits of its custom Kryo CPU cores and the integrated X8 and X12 LTE modems in the Snapdragon 650 and 820 respectively. Towards the end of the post, Qualcomm mentions that the two latest smartphones from Sony "incorporates Quick Charge 2.0 ... for up to 5.5 hours of power in just 10 minutes of charging, and a charge that can last up to two days". Now whether that bit about Quick Charge 2.0 is a typo or not remains to be seen, but at this stage, it is highly likely that the Sony devices will come without the latest version of Qualcomm's fast charging technology.
Qualcomm has already officially confirmed that the recently-announced LG G5, which also runs on the Snapdragon 820, has support for Quick Charge 3.0. However, not all Snapdragon 820-powered handsets come with that new fast charging technology from Qualcomm, as the two latest smartphones from Samsung - the Galaxy S7 and S7 Edge - have already been confirmed by the San Diego-based chipmaker as packing support for only Quick Charge 2.0 and not 3.0. Both devices are powered by the Snapdragon 820, and there's no official explanation from either Qualcomm or Samsung as to why the latest flagships from the South Korean company lacks support for the new technology from Qualcomm.
