Tested: The OnePlus 5T is the fastest-charging smartphone right now

Tested: The OnePlus 5T is the fastest-charging smartphone right now
From Engadget - December 9, 2017

The good news is that most of the premium Android phones these days offer some form of quick charging via their USB-C adapters. In the case of the latest iPhones, you can get fast charging, but only if you pay extra for both a 29-watt power adapter and a USB-C-to-Lightning cable (about $68 total). Yes, I am serious.

For our first round of testing, we wanted to find what battery percentage these phones could reach in 30 minutes of charging with their included adapters. The phones were on, but the screens were turned off. With the iPhone 8, iPhone 8 Plus and iPhone X, we used both the standard AC plug and the fast-charging gear to bring you both sets of results.

The OnePlus 5T led the pack, reaching an impressive 59 percent in 30 minutes. The advantage for the OnePlus? Unlike most other Android phones, it does not use Qualcomm's QuickCharge technology. Instead, it employs the proprietary Dash Charge, which delivers higher amperage than QuickCharge and uses dedicated circuitry in the charger itself for heat management. (Android Central has a great explainer on how Dash Charge works.)

The next-best phone in the first round of our testing was the LG V30, at 53 percent. The iPhone X, iPhone 8 and iPhone 8 Plus were all close behind, at 50 percent, 49 percent and 47 percent, respectively, when we used the fast-charging gear Apple sells separately.
