Im not a fan of the quick charging standard being forced as it sounds like it will be one hell of a step back for anybody on a oneplus/oppo phone. The quick charging there is absolutely amazing. Im on an older version but even then my 1+ 7 pro charges fast and never gets hot while charging. Compared to PD or QC it is leagues better.
OnePlus 9 Pro (and previous 7 Pro) owner chiming in. OnePlus was quick to market with good fast charging but it's not all that special these days. You'd never be able to practically tell if my phone used QC 5 or Warp Charge 65T for instance.
But that note aside QC/Warp Charge/<marketing gibberish name here> is just out of specced USB PD and most (including OnePlus) have already moved to supporting in spec USB PD on top of their proprietary modifications. The law is written to support your use case:
"2. Hand-held mobile phones, tablets, digital cameras, headphones, headsets, handheld videogame consoles and portable speakers, in so far as they are capable of being recharged via wired charging at voltages higher than 5 volts or currents higher than 3 amperes or powers higher than 15 watts, shall:
(a) incorporate the USB Power Delivery, as described in the standard EN IEC 62680-1-2:2021 ‘Universal serial bus interfaces for data and power - Part 1-2: Common components - USB Power Delivery specification’;
(b) ensure that any additional charging protocol allows the full functionality of the USB Power Delivery referred to in point (a)."
and because the law doesn't allow bundling chargers anymore you're free to pick whether you want to use a standard USB PD charger (which the device must support) or buy the manufacturer's proprietary charger (which the device can optionally support).
Did they finally get rid of the can't charge very fast while the screen is on and gets hot enough to cook eggs while charging issues with QC5? Because at least with QC3 and previous that was a major issue.
