Tech tips Shorted USB data lanes signal a mobile phone the availability of indefinite charging speeds if manually supplied with a voltage.

This could be useful if your mobile phones happens to only support MediaTek PumpExpress fast charging, but with the help of a two-port USB multimeter (one with data lane pass-through, the other one with shorted data lanes) and a Qualcomm Quick Charge trigger (manually sends voltage request signals to charger), one can manually request the higher voltage necessary for charging fast.
