USB-C port limited to Quick Charge v1.0?

If somebody opens up their ZMAX PRO and looks at their battery and circuitry we might be able to determine if the phone could withstand a fastcharge 2.0 or 3.0. Just because the chipset can handle it does NOT mean that the battery can. And it does NOT mean that the circuitry dealing with charging could withstand such a current. If the phone is found to be able to fully support 2.0 or 3.0, then a custom kernel/recovery could allow the phone to charge at 2.0 or 3.0 speeds.

I'm going to say this now, it doesn't take that much to test things like this and I highly doubt ZTE developers disabled 2.0 and 3.0 because they didn't have time to make sure it was going to work safely and properly on this phone... As detailed before, this phone can become warm during heavy use which means that there are thermal issues here, and my guess is that 2.0 or 3.0 is disabled because the phone would overheat and we all knows what happens to batteries when they overheat... Now I'm no expert on any of this, but I'm very into computers and phones so what I said shouldn't be too inaccurate.

TL;DR
Even if the chipset supports 2.0 or 3.0, it has been disabled for a very good reason.

Aha, things are interconnected even if only indirectly - the larger screen + higher resolution already contribute to higher heat... so would more gigabytes, NFC...
And then there's the cost budget for that terrific price point.
 
Some findings on the just - received Aukey 3.0...i posted that special on the ZTE main area.

I used two apps - Ampere & Electron.

Firstly, the original Zte cable is high quality and performs equally to the Aukey cable, which also looks well made.

I'M GUESSING total charge time to be 75-80 minutes, someone else will have to play guinea pig.

BOTH Aukey 3 and phone stay warm or cool the entire time, while also using the phone simultaneously.
With all other charging adapters- 2.0, original zte & others belonging to tablets / other phones... both phone and especially adapter get Hot.

Aukey charges phone @ higher voltage 4+, from the start goes to max much faster + stays closer to the max- and the min/max variance is smaller.

So no, 3.0 not able to raise the max, 2100, HOWEVER... it is making a significant difference because of its efficiency.
It is feeding juice at flexible, in between amounts - rather than the presets of 2.0 - varying them to whatever the phone can handle at a given moment.

There's also an obvious lesser power leakage / waste given the much lower temperatures.

It's a pleasant surprise.
Is it worth paying extra?
Maybe with multiple devices, especially tablets & portable power packs.
Yes, less heat prolongs phone & battery - but we upgrade far too often.
Ehhh...
 
I purchased the CHOETECH Qualcomm Quick Charge 3.0 from Amazon, and received it today. When I plug it into the ZMAX Pro it shows fast charging. It shows it when the phone is off and on the battery screen.

I did notice that the battery did charge faster, how much, I don't know. But I will do a test this weekend.
