One thing that the various smartphone manufacturers and components for such, seem to have stranded is the technology used on batteries to power the various devices. The only development seems to come from Qualcomm with its technology Quick Charge arrived at the 4 + version, which even if it has already been back a year and a half, seems almost impossible to find on the latest generation of smartphones.
You can therefore count on the fingers of one hand the smartphones that are compatible with the 3.0 Power Delivery as well as the Quick Charge 4 + of Qualcomm, but between these devices dominating the scene is our beloved Xiaomi, which can count well six officially certified smartphones to the fast recharge standard. Virtually one third of all the smartphones which are currently compatible with this technology, considering that they are in total 18 and that different manufacturers are made by 9.
Xiaomi holds the record of smartphones certified by the Quick Charge 4 + standard
Undoubtedly, it is quite a boast for Xiaomi to line the models at the forefront Mi 8, Mi 8 Explorer Edition, Mi 8 Pro, Mi A2, Mi Mix 3 and POCOPHONE F1 while the remaining smartphones belonging to this stable of testimonials of Quick Charge 4 + are: AGM X3, BQ Aquaris X2 and X2 Pro, LG G7 ThinQ, LG V40 ThinQ, Nubia Z17 and Z18, Razer Phone and Razer Phone 2, Qiku N7 Pro, Smartisan R1 and ZTE Axon Pro 9.
Many have instead tried to develop their own fast charging technology, such as OPPO, Huawei and OnePlus and it is rumored that Xiaomi could also think of something similar. But in reality Lei Jun seems to be more conservative from this point of view, since Xiaomi manages to make better use of the present standards and, moreover, it is better not to risk it as done at the time for the proprietary processor (do you all remember the Surge S1?). We remind you that compared to the previous standard, Quick Charge 4+ guarantees a 15% reduction in charging times and a simultaneous 30% improvement in efficiency.
