I am wondering about charging options for G7 and ask about two particular which I am most interested about.
1. Immediately when I got it I thought "cool, let's charge it a bit, let it sip a bit of a power from USB-C from the desktop", however there came the surprise No.1 - G7 is not fast charging, my 6P is (6P charges in 1 hour and something), G7 reported over 3 hours to charge.
How to fast charge the G7 from USB-C? I have a capable HW for that and Nexus 6P works that way.
2. I saw some mentions here that G7 supports 10W if not even 15W wireless charging, is that info verified? I am planning on buying a wireless charger (one at home, one at work), but I would like to know if there is pretty much any reason to buy 10 or even 15W chargers.

1. The desktop usually doesn't support fast charging. You need a phone charger that supports fast charging. The one included in the box will charge the phone for 1 and a half hours. You can of course buy a new one.
2. Any wireless charger will work but it won't charge fast. I tried Samsung's fast wireless charger but it charged the phone slowly. I would say, just use a cable if you're on a hurry and maybe a wireless charger when you're not using your phone.
But the thing is, Nexus 6P can, it is even stating it is fast charging via the very same USB-C port and cable, so naturally I am wondering why G7 is not.
Right now, G7 is being charged from USB-C just as long (considering what the estimation at the bottom of the screens is) I reckon would be charged via 5W wireless charger. I have dismissed the idea of more powerful charger, I don't need it, for that I don't mind it would be charging even over 3 hours.
And here's an example of how even though its a USB C port on the phone, not all features are implemented equally. Its either looking for some sort of resistance on the line in the cable or something else similar to that, as my Anker cables won't fast charge the G7 but will fast charge my Moto Z Play on my computer (which has the right port specs to support fast charge). If you look at the supplied cable with the G7, you'll notice that only one side of the C connector has contacts, and even then its a small amount of contacts that don't cover the whole side. more than likely the USB C cable you are using is fully built out so the phone is probably deciding that it won't quick charge when a fully spec'd C cable is used.
that's just my speculation
Nexus 6P doesn't support Qualcomm QC at all. LG G7 does.
Nexus 6P uses Quick Charge based on USB-C technology.
Different phones, different technology, different story.

Because Samsung wireless chargers use their own proprietary standard but not industry Qi which G7 is supported. G7 needs Qi capable fast wireless charging pad to enable 15W mode

Seems like Nexus 6P is capable of USB-C Power Delivery standard and G7 somehow is not. That's sad since I was hoping to buy one Anker or Aukey USB-C PD capable brick to charge G7 as fast as in can.

As for fast wireless chargers somebody should open a thread in https://forum.xda-developers.com/lg-g7-thinq/accessories about choosing fast wireless chargers. Like this one which is stated as supporting LG V30 with Qi EPP

Just got my 5x today, and it does "rapid charging" when I connect with the charger in the box, but when I connect using other USB cables/plugs (one supports QC 2.0, the other is a regular charger but supports 2.1A charging), I get a message that the device is "Charging slowly."
Are there other certain specs that a cable or charger has to have to take advantage of rapid charging?
Fast charging on USB-C is apparently very picky when it comes to cables. I havent't tried charging from the USB-A cables that I bought, but the reviews for one that I was considering said that the cable limited the charging capability to 500mA. I know little about qcomm's Quick Charging but I do know that it requires feedback from an enabled device before it will allow full power. I wouldn't be surprised if the lack of that feedback from the N5X was limiting current from the charger, but it definitely looks like a quality cable is the first step to success. Notice how thick the factory LG cable is...
Most cables limit current by a significant amount. Even factory ones. That's why the OnePlus One charger was so popular. The wall dongle was nothing special (2.0A) but the cable was thick enough to actually let it output that current. The only difference now is that our phone will actually tell us if it's hooked up to a crappy charger/cable.
Thanks for the reply, I'll have to do some hunting on Amazon for another cable and see what happens.
Appreciate it if anyone else can chime in too.
the Nexus 5X does not support Qualcomm Quick Charge, at all.
Thanks, I know QC is not supported, I was just offering up that I tried one, and that I tried multiple charges that support 2.1A charging.
Interestingly enough, if I use either of the QC certified chargers that I got along with my S6 (which only output 2A) I get rapid charging. Using an Anker QC charger (also 2A) I don't, and using a different charger (can't remember the brand at the moment, but also 2A, but not QC), I also get slow charging.
Hmm...
I've got a lot of devices that use micro usb, and several quick charge adapters and hubs.
From my understanding the OP3 will only quick charge when using the specific charger and cable that comes with it.
Now I'm wondering if I'll no longer be able to charge while driving and using GPS... only true quick charge seems to catch up to that kind of drain.
Anyone have an idea how this might work?

I too heard that only its own charger will charge it, but with root and custom kernels I can only imagine it'll get open to any usb-c cable
It would still charge with any cable but not at "Dash" rate!
OnePlus AMA on Reddit they say there are Power Management chips built into the Chargers so doubtful of it being opened up to any USB-C cable at Dash Charge rates.

Nope not true at all. Any charger with a USB-C cable will charge this phone. Confirmed by Andrew on Android central
I submitted a question on what kind of usb type C connector they used. I'm wondering if they circumvented the "official" type C connection in order to implement their dash charging tech.
Get the £25 Car Charger that will stop problems with drain.

Okay, reading through the thread, I feel like I can give you some definitive answers, and maybe solutions as well.
1) The Dash charging management IS offloaded to the charger. This means that only a charger with the built in functionality will trigger Dash charging safely. However, they WILL be selling accessories for cars, walls, etc. Might be available now. Keep checking, and if you're really curious you can call them and find out if they have any plans for the above.
2) ANY USB-C cable will charge the device, but not at QuickCharge/Dash speeds. This isn't a matter of triggering it in the device via software; the device is missing the hardware to make this work without the proper chargers. So it WILL charge, but at normal speeds.
(That being said, I ADVISE AGAINST using any charger that's not branded for the device. These things can and have caught fire and gone boom, and there's a reason they test the **** out of them before releasing them into the wild. The kid in China making $2/hr does not get paid enough to care if you die, so that's your responsibility.)
3) The inclusion of quickcharging means you can get to a destination with a plug and be reasonably charged within an hour. Unless you're a trucker, you'll probably just need to carry a charger around with you if it becomes THAT much of an issue, or keep one at your destination (I do this with my HTC 10, since i only have one plug. Works fine, lasts overnight and the 1 hr train ride to work.)
Hope this helps.
I have a nexus 5x that has usb-c with no issues. I use the stock power brick to charge and bought a respectable anker usb to usb-c cable for my pc. Can use that to adapt to my car charger to. You shouldnt have any issues. When my op3 gets here ill still use the same anker cable.
I've been using the Anker 4.8A / 24W car charger for at least a year and have (quick charged) my Note 4, LG G4, Moto G, and other devices without any problems. But I've never owned a USB-c device, so I'm weary about using it.
I honestly don't want to spend another $100 on an extra adapter, cable, and car charger just to make it a little more convenient!
Well, while it is type C, and can charge at 2.1amps, it is also wise to understand the factory charger and cable are capable of so much more. It is essentially OPPO's VOOC, which takes the heat out of the device into the charger and pushes about 20 watts, even while the phone is active.
The below video (i came across) has a great comparison.
https://www.youtube.com/watch?v=gAS76EZ87dc
I don't wanna start new theme. So quick question. Does this usb-c support any hub with hdmi, full usb 3.0 (or2.0)and usb-c charging?
Keep in mind USB-C is the new standard, everything next year will be USB-C. So whats the difference between spending $100 on new chargers now or $100 next year when it is the only choice you have?
Also a quick google-foo shows there are several USB-C to HDMI/USB/USB-C adapters

Thanks for that info. I have to look that article up. I just wonder will is have USB-C Power Delivery 2.0 to Rapid Charge. I now know that not every smartphone that has a USB-C port rapid charges. Neither my Nextbit Robin nor HTC 10 do, and I later found out they weren't USB-C Power Delivery 2.0 compliant.
Not sure why you refer to USB-C to HDMI or DP but OP3 does not have video out support.
Think I'll just take the hit on my wallet and buy a spare Oneplus dash charger. I'm slightly annoyed they went for a protected system, when Apple did it we were unhappy, so far I've not seen the community complain about this new Oneplus 'feature'.

I was going to complain, but then I did the research on DASH/VOOC and realized it is best in class, better than anything on the market to date. Quickly Charge with little heat... I'll pay 30 for a 2nd charger. And if I am in a bind, I'll just use normal USB C and suffer as I do now with my 1+1.
My only grr moment is seeing a car charger is $30.

sorry did not see this. the oneplus 3 charges at a much slower speed using the stock nexus 6p charger. i checked
I use the dash charger at home and a standard 2.1A Capdase Power adapter in the car and a 2.1A Capdase Wall Adapter at work. Obviously only the Oneplus Dash Charger Charges at lightning speeds. But to be honest.the other chargers also do faster than normal charging. Im comparing from my oneplus 2 that one used to take forever to charge. I get a full charge with the dash charger in say abt 45 to 50 mins. And with the normal charger in about 1hr 30 mins. Which is still quite fast IMO. Oneplus 2 used to charge completely in about 3 hours. Im using the oneplus 3 cable with the Dash charger. The Oneplus 2 Cable in my car and an UltraProlink USB to Type C cable at work.
Tldr. Dash charger works super fast. Other normal chargers work just fine.

That's great, It takes me about 70-72 minutes for a full charge from 0-100%. On top of the speed, I really appreciate that it doesn't overheat. I feel more confident with any smartphone that doesn't overheat while charging.
I've had a nexus 5x before and own a pixel table. Both come with USB C port to charge. So i bought a itian qc3.0 charger at that time. (http://www.gearbest.com/chargers-cables/pp_389793.html)
Now i changed to the lg g6, but it refused to do the 'fast charging ' when i use that chargers qc3.0 port and even says 'slow charging' when connecting to the usb c output.
Is it the combination that's just flakey or did they put something specific in the original charger that comes with the lg g6?
I'm bit lost on the topic of chargers currently, anyone care to enlighten me on what should could would work?
Lg g6 is picky I think

Works fine with my wife's charger from her Galaxy Note 4 as well. ? (Pretty sure that's a QC 2.0 charger as well.)
Does LG not provide a qc 3.0 charger with their own phone ??
Mine came with a MCS-H06UR charger.
Rated @ 9.0V 1.8A / 5.0V 1.8A
After a quick Google search I've had no luck ascertaining if this is QC 2.0 or QC 3.0.
From what I can tell, my phone charges as fast if not faster using the 5V/3A charger that came with my 6P.
From what I've read online, the LG G6 also supports USB-PD.

Shouldn't really get hot once it's fully charged?
The charger that comes with it is a quick charge 3.0 charger and can completely charge your phone from zero in less than 2 hours easily. You have to use the cord that came with it though, or at least one that is compatible. If you look at the icons, you will see a different one than the usual charging icon. Pulling down the menu shows something about fast-charging when its active.
My experience comes from the Sprint version.

i use one from Tylt each night since im always on-call. havent had a problem once.
None of my QC 3.0 charger fast chagrge my G6. The QC 2.0 chargers do.
I've bought a Choetech wall usb charger, QuickCharge 3.0 with its usb type-c cable, and when I plug it on LG G6, it says that there's fast charging.
https://amzn.com/B019Q5WT6W
I do not believe the LG stock charger is qc qc 3.0 compatible because its fixed mat output at 9v is 1.8a
qc 3.0 defines the max amps at each voltage level from 5v to 9v to 12v
I ended up buying anker qc 3.0 chargers for my car and for ac wall outlet. also bought their nice braided usb c cable. every combination yields a fast charger notification in the drop down and the ampere app confirms this. also watching the real time output is impressive from all these chargers.
the benefit to using a certified qc 3.0 charger is that the phone will tell it exactly what amps to deliver based on charge & temp.
further, the G6 has a heat pipe to help cool the entire phone including the battery, to help prevent a galaxy note scenario.
wireless charging is slow Qi spec and is NOT fast like samsung. however, slow charging over wireless is great for overnight.
I use anker's qi charging puck and it works great except I have to remove my case. same with the samsung fast charger puck. my wife doesn't have to remove the case on her S7 to do regular or fast charging. LG's design is obviously inferior for the Qi to pickup and activate the coil.
Today Amazon delivered also this Anker dual usb car charger (QuickCharge 3.0):
http://amzn.com/B01K9MQ8WW
and when LG G6 is connected it shows that is in fast charging mode.
Those who bought QC 3.0 charger and those who trying different cables with LG G6 charger, Try Cable from Oneplus 3, I get an improved charging of 10-20 minutes less compared to stock LG cable
The issue might be the cable you're using. I've had no trouble fast charging using an old ASUS QC 2.0 charger, or a cheap car QC 3.0 charger. Even when using microUSB cables with USB-C adapter tips, but I'm using decent cables (mostly Monoprice and Anker).
I've confirmed that the charger that came with my G6 is QC3.0 (model MCS-H06UR, UK 3-pin). Using a USB power meter, the voltage will increase from 5V to 9V in small steps. If I use a QC 2.0 charger (stock charger from Note4/S7edge), it will jump from 5V to 9V immediately.

How much time does it take to charge fully? Did you record time ?
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).

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.

Lots of questions here...
G7 comes with QC 3.0 although the chipset can support QC 4.0 as per Qualcomm. I see on other forums that users can tell when their phone is quick-charging or slow-charging.
1) Does the G7 let you know what speed it is charging at? I'd like to know so I can swap out cables, chargers, Qi pad, to get the fastest charging rate.
2) Is there a difference between Samsung's Fast Charging, and Qualcomm's QC 3.0?
3) If a charger says that it is compatible with Samsung S9's or S9+'s fast charging, will it fast charge the G7?
4) is there a QC Qi pad that is compatible with our QC 3.0 phone? If so, can I assume that I would still need to power it with a QC 3.0 wall wart?
5) Will a USB-PD or USB-IF charger quick charge our phones?
6) What is the minimum QC cable type (USB 2.0, 3.0, or 3.1) needed to get the maximum QC 3.0 charge? Does it have to be a 3.1 cable?
7) I've seen that when I put the G7 on my 1st gen Qi pad (5W micro-USB) that the phone screen lights up, and a circle briefly appears with the charged percentage in the center (while phone is on stand-by). If the phone is unlocked and the display is on, a white window telling me it is wirelessly charging shows up and tells me how long until the phone will be fully charged (again, when placed on a Qi pad). It's currently telling me 19 minutes to full charge from 93%. Is there a way to get this remaining-time info while cable-charging through the USB-C port?
Thanks!

The charge rate of the phone irrespective of the chargers we use, it is controlled by the stock kernel. When screen is on, it lowers down the amperage (See Ampere App) to keep off the heat, vice versa etc. We need a custom kernel to have the charging amperes to be changed manually which is really cool. If we have a really cool custom kernel, the CPU governors should preset customisable governors (for smooth performance) and for the charge values, just look for a 3A charger, with the Kernel Adiutor change the values. Meaning the benefits of rooting gives us the complete freedom of our Android! If a 4A charger is detected by the kernel manager app, the charge values should show as "upto 4A even with the screen on! Then no need to be jealous of Dash Charging of One Plus!
I think this article will help you out... Breaks it all down... Samsung charger are not the greatest for fast charging but works better than a basic one... Ultimately I would say USB c to USB c with USB PD is your fastest with QC 3.0/4.0 being a close second..

I don't see that wireless fast charging is b supported by the g7 ... That's a Samsung gimmick ... But the Qi standard chargers charge at the same rate as a basic charger... The lock screen always tells you how long until full no matter what charger you are using and it will say fast charging, wireless or just charging... My observations have been around 1.5 hour for 60 percent to full so about 5 hours if dead, great before going to sleep and I missed it in my least few phones

Thanks! I noticed you do not have a G7 listed as a current phone in your signature. Is your answer above based upon your experience with Samsung phones and their charging system, or specifically with the G7 (or other QC 3.0 phones)?
I hadn't notice the charging speed on the lock screen, as I have the phone set to basically bypass it all the time (fingerprint, facial recognition, & geo-fence)...so I didn't even know it was listed there on the bottom. Thanks again...now I know it's there
Strange thing is I went through a bunch of permutations with cables (various generations), and charge blocks and Qi pads this morning, and with the phone starting at 93% charged, it made no difference in remaining charge time no matter what combination of the items I hooked up. I saw the standard "charging" memo with some combos, and the "fast charging" one too, with others. Can I assume that even though the phone might say it's fast charging, it ramps the speed/power level up and down as necessary due to the current state of charge, or heat or some other factors? Would it also possibly switch into fast-charging with more power if the phone was starting at a lower state of charge, or possibly cooler?Yes, I'll have to read the link above as it's probably covered there
"Fast Wireless Charging" is supported and working.
I have a RavPower 15w and 3 umdigi 15w qi wireless pads that all say wirelessly fast charging when connected. Needs an 18w QC2-3 charger for the input voltage ranges needed to work.
It is noticeably faster than a 10w qi pad and only slightly slower than QC 3.0 USB average charge.

Of the 2 Qi pads you mention, any preferences towards one or the other (or a different one altogether)? I have an Anker QC 3.0 charger I can connect up to it.
BTW.. I cannot locate a 15W Ravpower pad. What model is it? And is the Umdigi a model Q1?

My pixel screen went bad and the charging port went bad also... Just got the g7 so I haven't changed my signature or updated my devices...
Samsung Fast charge is basically qc2 ... And standard USB A to C do not support the higher current that USB C to C does... I notice fastest charging with my pixel USB PD charger...
And yes you won't notice as much fast charging from the top 20 percent of the battery to prevent over charging...
for me, from 25% of charge, the fast charge advertisement says 1 hour and 20 minutes (charge fast???????).... if i use a normal charger (not fast), the time goes to 1 hour and 31 minutes. this phone has a charge fast but very low fast

I know it's hard from a specs perspective as most are only 75% efficient so the 10w might only be 7.5w and 15w is actually 10w, which is why LG customer services expressly states you must use a 15w QI charger for fast wireless charging. Another problem is the specs aren't always accurate and updated devices might still have old specs listed. I tried a bunch before I found a couple I liked. The mophie streampad+ also does fast wireless charging but is listed as 10w.
The RavPower is a standup charger I use in the office, the other UmDigi chargers I have scattered around the house and in the bedroom.
RavPower: https://www.amazon.com/gp/product/B079C1QLCR
UmDigi: https://www.amazon.com/gp/product/B07DJ56LT5
Did a little charge test from 50 percent
Wireless charger =1h 40m
Stock iPhone charger =1h 14m
Both pixel USB C to C and stock fast charger =1h 2m
I'm in the market for a qi charger that can fast charge my Thinq g7. I see reports of needing 15W but not seeing many out there that have that spec.
I have seen a RavPower one posted here that is said to do it but the price is quite high for that model. Does anyone else have experience with fast charging the thinq g7 with a Qi charger?
I have Samsung Fast wireless charger. This present with S7. Fast charging battery of S7 Edge, S9+. But G7 didn't support fast wireless charging. And charging is slow. So you can buy what you want but charging with this phone will be slow.
I read this topic and wondering how G7 is going to wireless fast charge?

Just thought I'd add to this - the charger that comes with the LG G7 ThinQ (Verizon) is labeled with outputs 9V/1.8A and 5V/1.8A. My old HTC 10 charger is labeled 12V/1.25A, 9V/1.7A, 5V/2.5A. I haven't tried it on the HTC 10's charger on a measuring device to see actual power delivery, but at least on the face of it, if it supports those higher voltages and/or amps, you should be able to get faster charging than with the charger out of the box.
On the other hand, faster charging may in part be why the HTC 10's battery lifetime is dismal, and not once have I thought "boy I wish my G7 would charge faster".
Anyone tried qc4.0 ?
According to some sites ThinQ is capable of 27W (9x3) charging. I therefore purchased a Xiaomi 65W charger which outputs 9x3 but the phone charges only with 15W (5x3) so wasted money.
Yes. I bought 3 different chargers and also a watt meter. When charging with screen on max amps is 1A and 6-8wattage. When screen is off it goes up to max 16watt. And it doesnt matter which charger i use.
80min for a full chsrge isnt that good. But think that lg g7 released in 2018?
Vivos IC00 something charges full in 20min. 4000mAh.
Im sick of "..reduced charging speed cause it can in a long term reduce battery......" who gives..? Then if you notice a different is gonna take 3 years and if still got same phone. Switch battery.
Look at Tesla batteries whos battery lost like 10 percent after 30000 km. I mean..come on
Im on 72% now and it says 45min to full.
A specialised site reported it would charge at 27W (9V x 3A) but this is simply not true. The best it can charge is 15W (5V x 3A). Thats it.
