QC 2.0 Amps

I noticed in the LG v10 documents it states clearly that another charger will damage the battery.
The stock AC Charger only chargers @ 1.8a. That's not even Quick Charge 1.0 specs. So I'm trying to read past the marketing BS and see how many amps I can charge this phone on. QC 2.0 spec is 5v/3a. My old Samsung chargers are about 2.1 - 2.4a. as well as my car charger.
I don't see how this battery is any different and could be damaged by charger at slightly higher amps than the lowly 1.8a stock.
Also, has anyone found a screen protector in stock locally? I'm thinkin of going with a thinner plastic protector, made from Aliphatic, of course.

Quick Charge 2.0 changes the volts, it will change from 12volts to 9v back down to 5v

LG V10 support qualcomm quick charge 2.0 technology, check here:https://www.qualcomm.com/news/snapdragon/2015/10/01/lg-v10-device-creative-adventurer
any of the chargers which list on qualcomm site should be ok for charging the LG V10.
if you said the stock charger is just 1.8A, then LG make some current limit in the LG V10. however, you can just talk the current. For quick charge 2.0 technology , you can get 9V volt when charging, total power is 9V/1.8A (16.2W).
@LancerV, in our test, most of the qc2.0 support device, the volt will keep at 9v in charging. we never seen any smartphone can support 12V volt, and in the whole charging, the current become small, but volt keep at 9V around.
see our charging analysis for different device here:

If anyone who already get the LG V10, we would love to send free qc2.0 chargers for testing. Please just send us PM.
Thanks

I don't have mine yet, but I'm sure it doesn't state that, it should state something like 'may damage if not used with supplied charger', this is normal as all brands also state this.
also you can get a QUALCOMM QC 2.0 from many brands, and they all should work, I myself have one from aukey and a Xpower travel charger which work with even non QUALCOMM QC units.
I prefer to charge at normal speed, fast charging will probably kill your battery faster.
Qualcomm QC 2.0 chargers uses 12V/9V and 5V

The LG v10 does not "Fast Charge" and Samsung 2.4 amp and other "Fast Chargers" do not charge the LG v10 any faster than a standard old iPhone cube. QC 2.0 is different and it's referred to as "quick charge" to differentiate it. Remember the phone will only draw as much as it can handle regardless of the charger's amp ratings, unless faulty or incompatible. Many incompatible chargers will charge the phone at the same rate from start to finish, keeping the battery warm, which may reduce battery life. YMMV

The best QC 2.0 charger I've owned and used is the ZeroLemon Charger. Phone wouldn't get too warm, and it would taper off towards the end, the phone was cool to touch. I also use Aukey, Motorola Turbo and Tronsmart home and car chargers that are both fast charge and have 1 qc 2.0 port.
All of my TYLT, Samsung, misc. 2.4 amp fast chargers charge the v10 at less than 1000 mA~
When connecting an LG v10 with low battery %, it charges at 9v~ from 2400-2850mA with main screen off. Rate depending on various factors, including quality of charger and cable, at start then tapers off at higher %.

The V10 does have quick charging, not too sure if it's the qualcomm, the information is stated in LG V10 brochure.
28 minutes for 50% and 85minutes for 100%

I wonder if it has QC 3.0 capabilities, anyone know?

Yes the v10 has quick charging. At least qc 2.0~ as long as your main screen remains off. 60-100mins for 100% is quick charge, remember it's only "QUICK" from 0-60% after that it's normal to save the battery from dying out too quickly.
Slow normal charge takes 3hours+ to get to 100% usually..

QuickCharge 3.0, across 6 chargers, is somehow not working on my V20

I picked up a T-Mobile V20 2 days ago. Rooted it the same night, and tested out a few chargers I had laying around to make sure the ones I had, along with cables, worked properly after having most everything not work properly with my Pixel XL.
The stock charger would not charge my phone at more than 3 watts (but I never touched the stock charger until I started noticing the issue).
A Samsung QC charger, with any cable, would not charge my phone more than 9 watts.
An Anker PowerPort+ 1, Type C, QC 3.0 charger, with any cable (to include Anker cables and the Pixel XL OEM cable), will not charge over 12 watts.
Absolutely NONE of my QC 3.0 car chargers register as "fast charging" - these include an iVoler Type C and USB A, Anker USB A, Tronsmart Type C, with various cables. A standard cabled Type C charger from i-Orange does not say "fast charging," but seems to be charging at 5V/3A as it is MUCH faster than all the others.
The ONLY charger that is fast charging my phone is the Pixel XL OEM charger. Measured at the wall, it has peaked at 19.2 watts.
I'm really confused. I don't know if my QC 3.0 has been defective since I got the phone, or if plugging my phone into the USB PD Pixel XL charger somehow screwed things up...
Does anyone have any ideas here?

All my old QC chargers work and I'm currently using the note 7 oem one atm as it does not get as hot (charger not phone) as the LG oem one under load. What does the app ampere say your getting?

It takes a while, try a very low battery and give it 10 minutes or more screen off, must be cool too

I got an existing aukey qc 2.0 fast charging fine while using a Samsung adaptive fast charger also fine, I am waiting for my qc 3.0 aukey one to be arrived possibly tomorrow to see if I could charge faster and lower temperature than my existing ones, I cannot check the watts though

My phone is either defective (not surprising given LG's GARBAGE quality control) or the software has somehow screwed up from root, etc. (highly unlikely as I am the only one with an issue).
With that said, I made an interesting discovery. My phone, using USB Power Delivery, charges much faster than my girlfriend's, using QuickCharge 2.0 or 3.0. I tested this 2 times from 5% battery on both phones. I tested this with a QC 3.0 car charger and the OEM QC 2.0 charger. The difference is substantial... first test was about 40 minutes. My phone was near 80%, hers was at 55%. The 2nd test was only 15 minutes. Mine was near 40%, hers only 27%.

Don't remember what Ampere says, but it was <500mA. Also, I used a USB current meter. It hovered around 5V/0.5A no matter what charger I used. I don't have a Type C/Power Delivery current meter, so I couldn't test those chargers... but USB PD is CLEARLY working very well on the V20. Much better than QC.

It does not take awhile - takes <5 seconds to begin the QuickCharge process. Phone does not need a very low battery - will show fast charging regardless of the %. Does not need to be cool - fast charging is shown when the QC handshake occurs - not based on actual charging current. My girlfriend also has a V20. Every charger I tested with mine (which did not work), successfully QuickCharges hers.

Are you you using 56 k resistor cables?plus being rooted a kernel app would have a section to disable fast charge or enable it. Most devs disables by default. So if using custom kernel something to look in to. As I doubt there is anything wrong with your phone.

Just got the aukey PA-T15 qc 3.0 seems fast charging fine though I have no time for a 0% to 100% test yet

All of my cables are good. No custom kernel, and I've never seen a dev disable fast charging by default... that would be very unpopular.
Anyway, it seems that LG's recent phones, to include the G5 and V20, are actually supporting both QC 3.0 and USB PD. This is also probably why QC 3.0 chargers that use Type C do not work (the Anker PowerPort+ 1 in my case). On a C to C connection, with USB PD present, USB PD will take precedence over QC 3.0 (since QC 3.0 is illegal with C to C anyway). But that still doesn't explain why my phone doesn't QC via USB A to C... so I'll chalk it up to LG's garbage quality control.
I'm glad it worked out this way. USB PD charges my phone WAY faster than QC 3.0 charges my girlfriend's V20. So I would suggest you all dump QC 3.0 (because it's non-compliant to anyway) and grab USB PD equipment since it's the way of the future anyway.

I'm starting to think that there's something wrong with the way V20 handles QC 3.0. I'm in a somewhat similar situation with you, tested three different QC 3.0 using almost 10 different A->C cable (including the OEM cable) and none of them would deliver QC 3.0 speed. (I just came in a from Axon 7 and the difference between charging speed is night and day).
Additionally, I wish there's an app to properly identify what's going on during charging.
Using the built-in battery test from Service mode (see screenshot), it always says that I'm on QC 2.0 whenever I'm charging using QC 3.0 chargers.

My unit (LG-H990DS) is charging very quick though.
Using stock charger & cable, charging time is very consistent from 0 to 100%. 95 mins is all it takes.

The stock charger that LG sent with the V20 is actually a QC2.0 unit.
and with QC3.0, it'll take you less than an hour to fully charge.

I can't say for sure, because I have no way to get a baseline on how fast a QC 3.0 charger charge at the correct QC3.0 rate on the V20....
At least according to the battery test from the service mode menu, none of my QC3.0 chargers are being recognized as QC3....and it definitely doesn't charge as fast as 3.0 based on my previous experience with axon 7.
on The Axon 7, I can still be playing Mobius FF (which is very battery intensive) and still charging up at about 1% per minute.

I'm pretty sure our phone doesn't have QC3 as I just mentioned in another thread. I'm like.. 97% sure? I remember reading early on that it was QC2, and a blend of LG that got it a little more robust than that. I'm not sure all of what's required for QC3 to work, obviously the 820 SOC supports it, but, not sure why I read that we don't have QC3.,

FWIW, I have a couple of Aukey chargers. One is QC2, and one is QC3. They both "fast-charge" my phone, but I don't think I get the fastest charge on anything but the LG adapter. Usually it's fast enough for me, but I guess if I was 10-15% left, and I needed 100% in less than an hour, it might not happen.

I just picked up a US996 (Unlocked V20)... and found this site while trying to make a decision on buying new chargers, cables, etc.
I opened a chat with LG to ask them if the V20 supports USB-PD... and I got this response:
Merwin
Not that we can verify, Ryan we because we have not tested it. I highly suggest you to use the OEM charger of the V20.
Click to expand...
Click to collapse
So... no help from Merwin @ LG. It seems they're not allowed to comment on it, and can only recommend the OEM charger. I was unaware that it was only QC2.0, according to the testing above.
Has anyone done more testing since? Can I buy a USB-PD charger and C-to-C cable? Should I avoid QC3.0?
Thanks

I'm interested in this as well having bought 2 QC3 chargers and neither charge my phone as fast as QC3 advertises.
I have used my brothers stock Nexus 6p charger from Google and the times are about equal to my QC3 chargers I bought

I'm using a Samsung QC 2.0 charger for mine:
https://www.amazon.com/Samsung-EP-TA20JWE-Travel-Charger-Devices/dp/B00TEUVEIO
I use it because I lost the LG one. It does quick charge but I can't measure the rate in the service menu. It just stays blank.

This is real easy, it happens with qc 3 on my v20 and s8+
The phone does not quick charge when the battery is warm or when the screen is on. Its really that simple. You can get faster charge times using a qc 2.0 charger or a dumb 18 watt adapter. Neither one is as picky about sending power to a warm battery, but your batteries life will be shorter than it was designed to be.
QC 3 will charge a cold empty battery faster, but in real life, it will preserve your battery over fast charging the phone.

Tronsmart 33W Dual USB Car Charger with Quick Charge 3.0

Has anyone tried the below charger with the Mate 9? I thought it should fast charge since it's 5V 3A, but I'm only getting around 2A according to ampere. Trying to figure out if it just doesn't work or if I got a fake one.
USB Type C Car Charger,Tronsmart 33W Dual USB Car Charger with Quick Charge 3.0 Technology.Attached USB C Cord for Nexus 6P, Nexus 5X, LG G5, Pixel C (Benson Leung Approved) https://www.amazon.com/dp/B0146FK3G0/ref=cm_sw_r_cp_apa_9rWSyb3FQ80Y1

It's not going to fast change since it's 5v and not 9v like the OEM charging block.

Thanks. I mistakenly thought if it could fast charge a Pixel or 6p, it would fast charge the Mate 9. It does seem to be charging faster than a standard charger so that's good at least.

No, the Mate 9 uses Huawei proprietary super charging technology and he accessories today don't have it. We have to wait for more devices from Huawei to come out or companies are given the ability to use their tech.

Yeah, I knew it wouldn't be able to get super charging speed, but I thought it would be able to reach fast charging or whatever the middle speed is called.

[CONFIRMED] .152 Firmware Update ENABLE QC 3.0 Fast Charging.

EDIT : Confirmed. This phone support QC 3.0 now.
Come a bit as surprise,
Updated my P20 Pro C636 to .152 Firmware,
And noticed right away that now IT DETECT my QC 3.0 battery pack charger as Fast Charge (Two Thunder Icon Appear) and it charge with High Current,
Someone who already on .152 and have QC 3.0 charger in their belonging might want to test it as well.
But anyway, this is good addition for me. Since now i can have one battery pack to fast charging all my phones.

By "wall quick charger" is it QC 3.0 ? Or 2.0 or standard fast charger ?
Because this phone wasn't meant to support QC standard to begin with, and supposed only work with Huawei Proprietary Supercharge technology, thats why i quite surprise when it now show it as fast charging when am using my QC 3.0 charger.

Not to burst the bubble but fast charge through Huawei's own charge gives up to 4.5A, yours only gets 2.5A and that's not fast charge but possible quick charge that Qualcomm uses.

Yes, that i know. LoL
but prior to this, even using QC 3.0 charger will only give me less than 2A, since it only act as normal fast charging,
so, this might be not doing any miracle,

That calculation on the screen is innacurate for most of the time. Because it fluctuate often.
And since his battery is on 70 its normal that the charger doesnt supply full current/volt,
That just how it designed.
And you are right,
For most of the case, our phone will be fully charged in around 2 Hrs using supplied charger

Go to MangusZen HurUpdater thread. That thread have all info you need.

Be careful with Huawei Power adapter:

Basically, when the charger is unplugged, the adapter runs in 5V mode, which is safe and good. But when the tablet is connected, then it is upgraded to 9V mode. any USB devices connected with a splitter on the charger wire will receive 9V also! This near doubling of voltage could cause devices to be fried, so make sure your Huawei power adapter isn't powering any hubs!!

Good catch!

I thought charges and/or device ports had a regulator to control input voltage?

Most electronics with a USB port will only be rated for say 5v, or maybe 6v to allow for naughty USB power supplies. 9v is nearly double 5v, and on sensitive low-tech chargers, like resistive ones that charge 18650 or whatever, you could expose the battery to a much higher voltage than what it should have, which could cause an explosion or whatever. I used a fan since it should be able to handle the extra voltage quite happily.

What do you mean fan?
Used a fan to cool what?

There is not problem at all. Qualcomm charge technology and USB 3.1 do the same. The charger and the device negotiate what voltage they want to send the same power but less current (more efficient). You are not supposed to o what you did, it your fault and not from Huawei.

what I was getting at is that if you were to use a splitter, like I did, then be careful, as the voltage might raise. This is not a concern most of the time, but it's good to just be careful.
My OnePlus 5T and it's dash charging only works when these 3 conditions are satisfied:
Dash charger
Stock OnePlus lead
Nothing else plugged in
otherwise it will default down to normal. It's a shame that this didn't happen on the Huawei charger, but hopefully this means that it will be easier for implementation for powerbanks, I can't find any dash charge power banks. And also apparently Huawei phones usually play nice with other chargers. (USB-C power delivery I'm not sure on this device).

And also apparently Huawei phones usually play nice with other chargers. (USB-C power delivery I'm not sure on this device).

I am just annoyed that Huawei do not use QC or USB-PD standards and I must use their charge to charge fast. I do not mind the 9v as my QC devices charges fast on the Huawei charger but not the other way round, forcing me to either change all my chargers or carry an extra charger.
Not sure if you are talking about FCP for in or out of powerbank, I have a Tronsmart powerbank that supports both QC3 and FCP out. It also supports QC in, which means it MAY charge faster with the Huawei's stock charger. I had not tested it that way yet but I think it should as the Huawei charger charges my other QC devices at QC speed.

I know your trouble, I have a OP5t, and that charges at 7.5W from my Huawei charger, when it can charge at 20W using dash charger, my mediapad charges at 10W from the dash charger, out of 18w capability. I do look silly carrying round two chargers with the same plug on them!!
Yeah no dash charger power bank, at least there is a Huawei FCP one like you said, I might get that as my next one, but I've got a lovely EC technologies powerbank, and that only does 10W no matter what, shame really as it is 82whr (massive!).

Luckily (for me at least!), I do not normally carry my M5 around and therefore do not need quick charge on it. Even if taken on holiday, it can charge overnight in the hotel. However this put me off Huawei (and OnePlue, Oppo and any other brands that do not use QC standards) for my future purchase.

Wow, I didn't realize how bad this bites. MediaPad was my first QC3 device. Used it's charger in my bedroom. Then got a LG v35 QC3 phone last week to replace old Nexus 6P (USB C-PD). So excited to see the Huawei charger fast-charging both devices. So irritating to now realize that the LG QC3 charger won't fast charge the M5!
And Huawei is using a proprietary QC3 charging mechanism? ie. are there any compatible chargers on Amazon or only the charger from Huawei will fast charge the M5?

Sorry, Huawei does not use QC standards but their own FCP/SCP instead. QC chargers will not fast charge Huawei gear but Huawei charger MAY charge QC gear fast.

So if I plug my M5 into a standard QC3.0 charger (9v I think), does it at least charge somewhat faster than a standard, non-QC charger? I would assume so. And are they're any 3rd party fasxt chargers compatible w/Huawei's dumbarse proprietary QC3 charging?

No it doesn't, as confirmed by a V/A USB meter. It will only top out at 5V/2A.
I repeat again, Huawei does NOT use QC3 technology, but FCP/SCP technology. If you are looking for a charger that can do both QC and FCP from the same socket, read through the tread again as I had already posted a brand and model that had been tested and confirmed to do both.

Ah, sorry, me dumb and had in my head that M5 was QC3. Now I get it -- FCP, not same as QC3. OK, I see your link and several other chargers compatible w/QC3 and FCP. Thanks!

Hi,
I have a ThinkPad E580 which comes along with a charger Type-C, on the charger has been written : OUTPUT: 20V-3.25A / 15V-3A / 9V-2A / 5V-2A
Is it safe to try charge my MediaPad M5 by this charger?

I had used USB PD adaptors on the M5 before and it charges fine, but not quickly.

My Pad (M5 10.8 WiFi) charges via USB PD with 18 Watts using the 9 Volt Profile. What doesn't work is Quick Charge. Power delivery works fine

Is there anything special about the actual Huawei furnished cable? I need a longer one than what was furnished.

Nothing whatsoever
But get a good one that supports high wattage.
Some cables only transmit 5 watts
Meaning 5v and 1 amp
