Anyone here have tested the difference in charging speeds on Redmi Note 7 based on the charging technology?
I only have QC 3.0 adapter, and while the initial charging is faster, the time it takes from 0-100 is almost same as the box charger. Redmi Note 7 supports QC 4.0, and QC 4.0 is also compatible with USB-PD. While QC4.0 charger is still scarce, USB PD is pretty common.
So I wonder if there's any difference in charging speeds between QC 3.0 and USB-PD/QC 4.0 in Redmi Note 7.

I have charge my rn7 with power delivery 18watt it took 1% for 1m. (15-80)
however, qc4 supports up to 27w. maybe anyone has a laptop usb c charger that can try with this?

Our snapdragon 410 supports quick charge 2.0, is some hardware limitation in our device that dosn't allow to charge at a higher speed? the battery needs to be compatible? etc

Our battery only receives 5V/1A.
You need a 1.5 Ampere Quick Charge enabled charger to use that feature.
Xiaomi ships two kinds of chargers with the Redmi 2 ( based on region) : one is a 1.5A QC2. 0 charger and one is a 1.0A QC charger.
If you're looking to buy one, I'd recommend Microsoft Fast Charger
It can be enabled through kernel modifications.
As Redmi Note 3 has got the feature through Franco kernel.
Hello,
Has anyone compared charging times between QuickCharge charger and using a USB-C to USB-C cable charger?
The reason I ask, is because QuickCharge doesn't seem to be all that fast. Plus, when I had my Nexus 6p on the charger using straight USB-C, it seemed to charge really fast. Wondering if I should use my Nexus USB-C charger or not.
The s8 doesn't really support usb-c power delivery, it has its own adaptive charging running at 15watts(9v*1.67v). You will probably get around 10 watts tops using any other charging method.
If yes, Then let me know which brand of charger should i buy!
No.
I think it only supports QC 2.0, though the QC 2.0 charger does not come out of the box. But imo, who needs fast charging when the battery life can last up to 2-3 days with this phone.
in it's specs sheet in gsmarena quick charge 3.0 is listed. That's why i asked.
anyway, what's the best quick charge 2.0 charger out there? and will that charge the device faster than the original charger?

The 625 snapdragon processor does support Quick Charge 3.0, but Xiaomi prohibits using it i guess to cut cost, i know some user who try to use QC 3.0 on this phone but it doesn't work, to be honest i'm also not sure about QC 2.0, my advice is you should try testing it first by borrowing QC 2.0 charger with some of your friends/relatives that has QC 2.0 charger before attempting to buy one.

No QC 2.0 support for me, tested with new xiaomi powerbank 10000mAh, ampere show max usb current 500 mAh instead of 2000 mAh. However from measurement I can get 1700-2000mAh so still charging fast enough.
Redmi 4 supports Fast Charging (i.e. about 2A), not any form of Quick Charge. The chipset supports it, but as Xiaomi have decided not to pay Qualcomm the royalties they charge for QC, it's disabled at a low level in the phone. It might be possible to enable it via custom kernel, but I don't think it's been done yet if so.

you mean that from the measurement you're getting a CURRENT reading of 1.700 to 2.000 Amps, right? Because mAh is the capacity measurement while A or mA is the current measurement?
To be on topic, the hardware inside (global version - snapdragon) and the battery support QC v1-3 specs but quickcharge is disabled.
The phone will charge at 1.8A or 1800 mA for about 10 minutes between 20% and 55%. battery capacity.
the current raise up while you changed to a qc 3.0 adapter.

CURRENT WILL NOT RAISE ABOVE 2A by now. ONLY VOLTAGE WILL BE INCREASE, but with decreasing current.
I tested a bit :
with QC 3 compactible Aukey PA-T16 charger, Ampere shows 2030mA
with Anker 40W 5 port charger Ampere shows 1830mA.
I have a Redmi 4 (standard edition) and I also have a USB Ammeter/Voltmeter which I can use to measure actual voltage and current flow into the device.
Using a standard 2A charger, the device accepts 4.9-5.1v (average 5.0v) at 1.5A (1500ma), and rarely exceeds this due to the voltage drop of the charger circuit /transformer in the wall plug.
Using a Quick Charge 3.0 charger (Capable of 5v, 9v, 12v and dynamically 5v-12v for QC3.0), I was able to charge the Redmi 4 at 6.2v/2.1A. The peak voltage was 6.24V and peak current 2.4A (momentary).
The Redmi 4 will charge at 6.2v and 2.1A with a Quick Charge 3.0 compatible charger when the battery is totally flat. As with all batteries the current slowly decreases as the internal resistance of the battery increases as it charges.
This is 13 Watts of power, 1.7 times higher than the 7.5 watts provided by the included '2A' charger. Thus, while it does not officially have QC3.0 capability, the device is still able to utilise a slight boost from the chipset's compatibility with higher voltages. Realistically, this means you could cut down on the charge time by around 1/3, and even moreso when charging from, for example, 0%-30%.
So I'm trying to figure out whats the fastest charging method for the lg v35 available so i can buy a new charger with that capability. Anyone have any ideas what that would be?
For USBC i'm looking at 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A , which of these usb pd options would it work with? Also is this phone a QC 3 or 4 capable phone? Thanks
Trying to see if this would increase my charging speeds:
https://www.monoprice.com/product?p_id=30948
My old Nexus 6 quick charge brick does nicely with a usb a/c cable
LG v35 is QC 3.0.
Neither or my Google PD chargers for my previous Nexus 6P will fast charge my LG v35, but my Huawei MediaPad M5 charger (FCP --> 18 watts) will. I think QC3 is a little more watts, like 22 so I'd get slightly faster charging w/QC 3 charger. Would really like to identify a charger that will fast charge across QC3, FCP, and PD. Not sure that Monoprice one will.
This device does PD up to 65 watts plus two 2.4amp us ports and also has one QC3 port. I love it.

If I charge Oneplus 8 pro with lets say Car Charger with supported standards PD 3.0/QC 4.0/ QC 3.0/ AFC , is there a downside? Or just slow charging speed?
And, is there a downside if I need to charge my phone at work for example to take notebook USB Type C charger and plug in... (again apart of slow charge)

The rate of charge just be slower, otherwise no problems, no.
I just got the 8 pro yesterday, IN2025. From what I've read and i just tested your charging speed will be better w/ PD as the phone does not support QC anything and just treats as it regular charging.
I tested the charging at ~70%.
USB PD, 4.2V/1.8A - 2A
QC 3.0 4.2V/1..2A
Warp Charging, 4.2V/4.8A
Warp with regular cable, 4.2V/1.2A
Regular charging 4.2V/1.2A
Hope that helps
okay so my previous phone was a PD 3.0, I have a bunch of charger that are 3.0 which support up to 65W. What would it do with the OnePlus 8 Pro. will it be limited to 35W or will it go higher?
Always limited by the phone max specs.
so in that case I should still get the 30W from a PD 3.0 charger to the OnePlus 8 Pro?
Cause I don't want to spend $50 for a Warp Charge Car adapter specially if my PD 3.0 charger can provide the same amount of wattage

No, you will not get 30W from your PD charger, it will max out at 15W.
OnePlus only supports PD at 5V, likely because Dash charge only uses 5V. PD caps out at 3A for 5V, so 15W. PD achieves higher wattages by increasing the voltage rather than increasing the amperage like Dash Charge (hence why PD cables are generally thinner than Dash charge ones).

So in your case all chargers give less than required charging voltage?! AFAIK, only dash/vooc charges at battaries max voltage. others supply 5v. check your data
