Hello, I searched Google for quite a while but couldn't find any solution. I want to add the QC and pd fast charging standards to the phone as it only has vooc or dart built in by default. I don't know if it is possible

Qualcomm Released Quick Charge 3.0. New Chargers Would Soon Show up.
I see many people are discussing about QC 2.0 fast chargers. Now Qualcomm official released the next generation fast charge technology--Quick Charge 3.0.
Quick Charge 3.0 offers a more granular range of voltages: 200mV increments, from 3.6V to 20V. It means better efficient compare with previous Quick Charge Technology, Qualcomm said 38% more efficient than Quick Charge 2.0.
Quick Charge 3.0 can be implemented with USB Type-A, USB micro, USB Type-C, or proprietary connectors. The USB Type-c is the trends and future, More and more device will come with type-c port. The QC3.0 is fully implemented with type c, which means we might see a lot of device which have type c port and at the same time support quick charge 3.0.
Quick Charge 3.0 will be available in newest Qualcomm Snapdragon processors, including the Snapdragon 820, 620, 618, 617, and 430.
It’s 100% backward-compatible with Quick Charge 1.0 and Quick Charge 2.0 devices. so don’t worry about no device support,if it detect your device don’t support QC3.0,it will direct give you 5V/9V/12V QC2.0 standard.
I believe there will soon come some QC 3.0 chargers. I am looking forward to trying one!!
Besides, it is said that the QC 3.0 fast charger is safer for those phones compatible with QC technology. Because the current is aroused step-by-step. Well, I don't know how to explain it clearly, if someone could help explain, please, I will be a good learner!
Hi,
CM roms or GPE ROMs support fast charging ? beacuse with my Samsung Fast charger it has a very slow charge like complete in 2-3 hours.
Thanks !
Samsung charger won't work on this device for fast/quick charging. You can blame Samsung for that (or for manufacturers not all using the same fast charge standard). Samsung does not use the Qualcomm QuickCharge standard, inherent in the Snapdragon chipsets. Samsung decided to use their own proprietary fast charge technology, which only works on their devices. Probably at least part of the reason, is that Samsung does not always use Snapdragon processors in their devices.
With the M8, you need to use a charger that specifically supports Quick Charge 2.0, which will either say QuickCharge 2.0, and/or have the QC logo like this: http://www.androidcentral.com/sites/androidcentral.com/themes/android_visor/images/badges/quick-charge.png
Also, QC 3.0 compliant chargers will also work on this device, but at QC 2.0 speeds (not the faster QC 3.0 charge rates). Might be a consideration if you are going to buy a QC charger, and want some "future proofing" for a possible future QC 3.0 device.
I was reading that some higher amp rated chargers (not QC compliant) may charge slightly faster with QC devices, but you'll never achieve full QC charge rates. And from what you're seeing (and others have reported similar) is that the Sammy charger doesn't give you any faster charging then the "standard" (non-QC) charger that came with the M8.
Not sure (not a CM or GPE user myself), but I believe with the proper charger, QC 2.0 will work on the device, regardless of the ROM, as the feature is built into the chipset hardware itself. But you can probably check the ROM threads to verify that.
So..........anyone know if it's Qualcomm Quick Charge 3.0 or something else? I found one report that claims it's QC3, but not sure of their source. Not sure if anyone saw any "hands on" videos where they were able to ask Google about it.

Don't know for sure, but I was curious and searched for info on the Qualcomm Snapdragon 821 that the Pixels use. The 821 does support quickcharge 3.0 so chances are the Pixels will use it.

EDIT: Well reading this https://plus.google.com/+BensonLeung/posts/GnjQBqAovnD it looks like Qualcomm quickcharge is not used, but instead they use the USB-C fast charging standard. " I would really prefer if they had mentioned Power Delivery, instead of "Type-C quick charging" which could be misconstrued as Qualcomm's proprietary tech. The Pixels do not use proprietary technology to charge. They use standard USB Type-C and USB Power Delivery."
Tried to post last night, but couldn't. As mentioned above, it uses USB-PD, and not qc 3.0. Many argue USB-PD > QC 3.0.
When I use a Qualcomm QC3 charger with my Pixel C, it rapid charges. QC3 supports a 5v3a 15w charge, which is the Pixel C's USB PD requirement. As QC3 scales its voltage and amperage, it's likely QC3 chargers will support USB PD at 18w too.
(I havent gotten it working the other way around, for example, the USB PD charger rapid charging my HTC 10 that uses quick charge.)
I just purchased an LG G7 ThinQ on Verizon in the US, coming from an LG Optimus G Pro, purchased in 2013. It's being shipped right now, so I don't have it to play with.
With that said, I'm a newbie to quick charging. I see that the phone comes with a QC 3.0 block, and that the phone is listed as being QC 4.0 compatible, as per Qualcomm's website.
I'm looking to order all new cables and chargers to take advantage of the higher charging speeds that this phone can allow. I'm not understanding though whether I'd be better off buying a car charger that is QC 3.0 or has USB PD. I realize that the USB PD would be the way to go for laptops and larger items, but for our phone, is there any difference? I do realize that I'd need a dual-ended USB C cable for the PD charger.
Also, has anyone tried using a QC 4.0 charger on the phone, and although Qualcomm says the phone has the 4.0 hardware, has LG enabled us to use it?
So the LG chargers can deliver 9v 1.8A.
The phone will recognize my 18w and other 45w PD charger, but I haven't managed to see any difference in the charging speeds, and more annoying, charging is pretty slow when screen is on.
I wanna buy a USB meter (PD compatible) to see what's the phone actually asking for, but I assume that it just sits at 15w max.
The reason I have a PD charger is because it allows you to have longer USB-C cables and it's compatible across more devices, like I can fast charger my Huawei Mate 10 pro with it, you can also charge iPhones with it.

This thread could be useful for you too: https://r.tapatalk.com/shareLink?ur...share_tid=3787343&share_fid=3793&share_type=t
USB PD is an entirely different language than QC 2-4. They negotiate and handle power different from each other. If you plug USB PD into a QC device it should default to 5v, 1 or 2 amp standard charging.
Use only QC 3.0+ equipment. That will get you the rapid charge you're looking for as it speaks the right language for the phone. I dont believe LG has enabled QC4 standards in the firmware although the chip supports it.
LG G7 is also wireless rapid charge, i get an almost QC speed on a 15w ravpower and umdigi wireless pads. Took me a few to find ones that were quality and charged fast. Most of the "10w" chargers dont actually put out 10w so they dont charge fast.

QC 4.0 is actually compatible with Power Delivery, Qualcomm did that in fear that Google would make PD mandatory.
And there can be handshaking between previous QC devices and PD chargers, since the most basic profiles are kind of standard (max 9v 2A).
So in this way I can fast charge a S8, the LG G7 and any other QC device with the PD charger and I can charge other PD and QC devices with my Huawei fast charger power bank (it's based on QC 3 delivering max 9V 2A).

Funny i was just reading an article about that. I suspect that would be a firmware compatibility issue again, as in: did LG enable it.
Great feedback and perfect timing

I just wished that phones would support higher charging rates via the PD standard.
I'm mostly sure that neither the S8 nor the G7 are taking full advantage of the max power output of their charger for long.
I thought that the charger might be under delivering, but connecting my PD 18w charger results in the same situation, I still need to measure it (need to buy a USB meter to have more details).
But using the same 18w PD charger I can charge the Mate from 20 to 50% much faster than I can charge the G7.

Hello,
Id like to know which quick chargers are compatible with the V40? I know it comes with a QC 3.0 in box but will a QC 3.0 Samsung S8 charger work just as fine?
Id rather not take the chance to damage a device, or is it better to just purchase OEM LG quick chargers?
From my understanding, QC is a standard by Qualcomm, so any charger following Qualcomm QC standards (it should say if it supports up to QC 3.0 for example) will work fine. It is not OEM dependent, and a bunch of brands like Aukey make third party QC chargers. Your S8 quick charger will work fine.
