It appears that some other brands like Xiaomi use higher amperage for their fast charging instead of higher voltage to deliver more power in addition to potentially more proprietary communication through the data lines. PPD likely has a lower current limit at the voltage a VOOC phone charges at too (apparently around 10A?). Mainstream 100W wires (20V 5A) might probably be “incompatible” even if the power supply were rated for higher amperage.

I do totally agree with you and hope for PD fast charging to be adopted, or for the PD standard to be made more flexible so that manufacturers can have what they want (but then again we will have the issue of USB-C where one connector does all but not all wires are made equal…).

Things just working as you expect them to is always very nice. If I buy a high wattage brick, I expect it to fast charge my phone.

My phone unfortunately doesn’t seem to support PD/PPS, but supports Qualcomm’s Quick Charge… meaning that it’ll charge in 2-3 hours from my laptop or a 25W/45W/65W PD/PPS brick… only at either 5W or 10W… but it’ll charge in an hour with a Qualcomm QC compatible brick or 30 minutes with the original 100W brick… :')

Also as an aside, the Find X8 seems to be using a silicon carbon battery - I thought that silicon electrodes expanded and contracted much more than previous generation batteries causing long term health to be worse…

It will be interesting to see if the battery health on these models really does stand the test of time. With the more efficient chip drawing less power, we can hope :)

Does it at least work with USB-PD to provide basic fast charging? That should be the minimum at this point.
