OnePlus phones have one of the simplest and cleanest UIs as far as android goes. The clean UI comes with an extensive feature set, such as an Engineering Mode app use to troubleshoot and test specific components and features. XDA-Developers found a certain feature deep within the Android 11 beta source code of the app for future OnePlus devices.
The Engineering Mode app mentions a Super Warp Charge fast charging feature pushing 65-watts into a OnePlus mobile device. The written code could mean that the upcoming OnePlus 8T series will support the insanely fast 65w charging. Features of OnePlus flagship devices are usually found on last generation Oppo and Realme devices. That said, Oppo’s SuperVOOC 2.0 and Realme SuperDart charging already supports 65w fast charging – marking the feature ready for OnePlus devices.
Lastly, the Engineering Mode app’s source code also reveals an Ice Blue version of a OnePlus 8T device in the works. It’s supposed to be the opposite shade of Ultramarine Blue. It’s safe to assume OnePlus to release another Blue-based colorway as seen with the previous 7, 7T, and 8 series.
