Quick Charge Support?
- Thread starter carlchan31

Based on the specifications off the Chinese website, supports only 5v/2a. Not sure hardware, software or licensing limitation.
I have bought a MiPad 4 (3+32).
If the QC3.0 charger is used, it will only up to about 12W. It still needs 2.5 hours.
Do you have any device that would measure the voltage and amperage??
It would be great to get the actual reading...
I have one Mi Pad 4 (3Gb/32Gb Wi-Fi) and with the battery at 20%, charging in a QC3.0 port, with the screen off it went to 1.85Ah at 5.05V. It was around 9Wh. So i can tell that it probably will go to 10Wh maximum and so it has probably only support for QC2.0.
I used a UGreen wall dual charger (one port QC3.0, the other is 2.4Ah) and the cable also a UGreen nylon that supports fast charge. They are found very easily in ebay and I strongly recommend this brand for charging (value/quality). For measuring I also used a very common usb tester that goes up to 5.1Ah/30V found also in ebay.
I can tell that with that same charger and cable, my Le Max 2 goes to a maximum of 24Wh(!) (around 8V/3Ah) when it was around 10-20% battery. So I can tell that the charger is at least outputing that power.

I confirm that no matter if used original charger or QC3 from Mi6 it can't charge 2-100% faster than 3 hours (usually 3h20m). Besides it doesn't show any notification about fast charging so this function must be locked.
IMO this is the biggest flaw in this tablet and I hope Xiaomi will do the same like with its Mi A1. The phone was released without the QC support, but it got unlocked with the Oreo update.

Xiaomi AD07ZM charger show 5V / 1.9A on USB tester with my Mi Pad 4 LTE at 40% battery.

using various chargers and cables, both with miui 9 and 10.
I can say that MI PAD4 - DOES NOT have QC. it uses regular 5V/2A.
on xiaomi mi6, which clearly stated to suppoer QC, you have a sign of 'lightning bolt' on the top, as well as on the lock screen.
Mi-Pad DOES NOT.

is this limitation in hardware or easily bypassable using magisk?
coz the Plus version got at least QC2.0 enabled.

that's what the specifications say, BUT mine does definitely not support any kind of QC, neither 2.0 nor 3.0. I have tried it with a variety of QC2/3 chargers and cables that all work fine for QC (QC3.0 in this case) with my Mi Note 3 ("Jason"). On the Mi Pad 4 plus it does NOT quick-charge: neither does the Pad show any indication that it does, nor do my indicator cables (that have different color LEDs for normal or quick charging), nor is the charging time significantly reduced when using a QC charger versus a "normal" charger.
So, in theory it supports QC, in practice it doesn't for whatever reason. It may be supported by the chipset, but may be blocked by the kernel or MIUI.
With this rom I get the Quick charging message, https://xdaforums.com/mi-pad-4/development/rom-lineageos-15-1-mi-pad-4-mi-pad-4-t3871520
But does it really charge faster? I think this is more in the firmware than rom itself.
Hi,
I got an MI PAD 4 imported to India and unfortunately lost the charger .
I got know NI PAD 4 needs a 5v 2a charger. Can i use the Mi India standard 2A charger as the voltages in india and China are quite same .
It is is tough to find an equivalent adapter for the MI PAD 4 here in India .
Could you please help me with any suggestions .. i am currently charging it through USB ports in my laptop but the tablet is nearly dead.
look forward to your response.

Input (line) voltage doesn't really matter for this kind of chargers, they do support a wide range of input voltage. What matters is the output voltage. If it is 5V there is no problem using that.
