Quick charging questions - LG G7 ThinQ - LG G7 ThinQ Questions & Answers

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..
https://www.digitaltrends.com/mobile/how-does-fast-charging-work/
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?
Sent from my LM-G710

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.

Hi guys, the Zenfone 3 deluxe supports qualcom quick charge 3.0 however it seems to be locked to the oem charger. Any other licenced qc 3.0 charger does not quick charge the phone. How hard would it be to get around this? Mainly for qc 3.0 powerbanks.

This is not true. I am using this one - https://www.amazon.de/gp/product/B01EH11AS8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
and the quick charge 3.0 works fine. I am still using the original type-c cable that came with the phone though.
Note: Make sure that you have plugged in the USB end of the charger correctly, push it all the way in. If it's only pushed in partially, then you may not be getting the full power for Quick Charge. You can verify this by using a tool like AIDA64 from the playstore and checking the "Charge Rate" under battery.
This is where I was told it's not supported.

Update: Sorry guys, I realized that the OEM charger is indeed much faster at charging. Read posts below.
postimg.org/image/6wis1rux1/ - using licenced qc3.0 charger
postimg.org/image/ndr13s0pv/ - using oem charger.
Further test screen off
15min charge with licenced qc3.0 gives 13%
15min charge with oem charger gives 27%
Same test with screen on (playing video)
15mins with either charger yields about 15%, no noticible difference. Seems like the oem charger throttles when screen is on.
All tests are run when the battery is below 20%.
Same oem cable used for all tests.
Using the oem charger to fully charge my phone does it nearly twice as fast as the qc3.0 charger.
Don't know how your able to achieve the same speed regardless of charger
Hi guys, I've been experiencing the same problem with original charger, that's very big and it's seems that didn't have quick charge. I've a samsung charger and with samsung charger it wroks fine. I'll try to well plug thw original , but, it's thinner samssung's one.

Interesting ... I stand corrected now regarding the "Fast Charging" on the lock screen.
I never used the original charger because I bought mine directly from Taiwan which has an US plug which I cannot use here in Germany directly without an extension.
I tried the OEM charger now with an adapter and yes you are right, the Charge Rate with the OEM charger is 2 times faster than with other chargrers.
OEM charger - 2900ma charge rate
Other charger - 1300ma charge rate
---------- Post added at 11:29 AM ---------- Previous post was at 11:02 AM ----------
Actually now I'm confused. When I plugged in the OEM charger, it said "Fast Charging" for a short while and then it says "Charging". The Charge rate also came down from 3000ma to 1300ma and down to 800ma when the battery is at 90%.
I will do some proper tests with the different chargers and post back.
Confirmed: OEM charger is much faster than other QC 3.0 chargers
When the phone reaches 70-80%, the charging rate will slow down and just trickle charge. This is normal as it can be dangerous to keep charging at Fast speeds when the battery is close to full capacity. So if your phone has 80% and you put it on charge, it will not Fast charge regardless of the charger you use.

Thanks for the information
I can also confirm fast charging doesn't work with my QC 2.0 charger. Interesting thing to note is it outputs 5V - 2A and 9V -2A. My guess is this charger from Asus that fast charges the Zenfone 2 would work on our phones because it has the same outputs if you read the description. It's worth a shot and you could always return it to Amazon if it doesn't work.

It would be nice to remove the red light when the phone is charging. Maybe it's something that can only be removed after rooting?

Unfortunately, even though the charger referenced above has the same outputs it doesn't fast charge. Seems you can only fast charge with the included charger. At least we can use our own charging cable. If anyone gets another charger to fast charge the device let us know. It doesn't appear Asus sells the included charger on it's webpage yet.
Not allowing the standard quickcharge charger to work forces people to once again purchase / replace current QC chargers.
One tick to the CONs side of the evaluation.

At this moment, I don't really think it's a CON side...
The quality of all those QC2.x/3.x charger are not even today (may get better in future, however I really doubt those cheap, knock-off charger from China). Some are good, some are outright bad. QC is quite sensitive with the voltage/current delivered by the charger (it's by design of QC, I believe) and not optimum voltage/current will shorten the battery life at best, create danger at worst scenario.
LiPo battery is really not designed to be charged in high speed. The associated temperature issues needs to be check very carefully and charge current needs to be controlled strictly to avoid dangerous thermal runaway. It cannot only be done by phone itself and need co-work from adaptor (switching voltage, for instance.) Thus an adaptor which have good communication with phone is a safety requirement as far as QC is concerned.
Same with me. I bought a wall charger aukey PA-16 and a car charger Aukey CC-T8. Using the ampere APP, The original zenfone charger gets 2800 mAh. And the aukey chargers up to 1300 mAh.
K6 charger also does not enable Quick Charge function on 570KL
Input type: 100-240V 50-60Hz 0.5A - Quick charge 3.0 output: 3.6V-6.5V-3A/6.5V-9V-2A/9V-12V-1.5A - Power: 18W
I am wondering if someone achieved any solution to remove OEM charger lock to use fast charge with third party Qualcomm Certified Chargers/Power Banks?
Sorry to resume this thread but i lost my oem charger and id like to get one that works with the zenfone 3 deluxe and quickcharge. Can anyone post a link where i can buy it or maybe the model number of the charger? The EU version would be nice.
Thanks
Any solution to the original question?

ASUS locked the fast charge function to the OEM QC 2.0 charger that comes with the phone (it will NOT work even with other ASUS QC 2.0 - or 3.0 - chargers, only with the specific type/"model" that came with the phone). Therefore we don't get QC3.0 - as advertised - at all. The QC3.0 compatibility with 3rd party chargers, powerbanks and car chargers was disabled with one of the updates, I think it was the Android 7.0 Update (that replaced Android 6.0) that removed QC3 compatibility. So... any ideas how to re-enable the QC 3.0 functionality?
Quick charge was disabled for other chargers from day one. I'm still on marshmallow (Android 6.0) and only the charger that came with the phone works with quick charge.

fast charging pickyness

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

I'm using the charger from my Nexus 6 and my G6 says that it's quick charging. Only QC 2.0 on that one though.

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.

Off topic a bit. Thoughts on overnight wireless charging. I have a great charging cradle that I want to use but don't want phone to crack at night from hours of heat. Sony z2 and z4v had issues with that

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.

OnePlus car charger

Hi everyone!
I have a car charger for my old phone, the OnePlus 3. But yesterday my Samsung Galaxy s8+ arrived and is now my daily driver .
My question is : Does a official OnePlus car charger (with dash charge) works for my Samsung Galaxy s8+? If so, does it damage the battery?
Kind Regards,

I have tried mine with the old OnePlus dash charger and though it works, the charge speed is crazy slow. The phone was reporting that from about 40% it would take 5 hours to finish the charge.
Am guessing there is something propitiatory in the dash charger that is causing this. I dont use it on the S8 anymore, incase its damaging the battery somehow.

Does a official OnePlus car charger (with dash charge) works for my Samsung Galaxy s8+? If so, does it damage the battery?

It won't damage the battery, but it also won't do fast charging as the Dash charging is proprietary and doesn't support Qualcomm's (also proprietary but much more widely used) Quick Charge 2 (or higher; QC is backwards compatible) that the S8/S8+ uses.
According to the car Dash Charger specs the standard (non-Dash) charge supports up to 5V at 2A, which is 10W. Compare this to the official Samsung charger's 9V at 1.67A (QC2), so provides 15W.

In theory then it should be able to charge the S8+ at two-thirds of the speed of the official charger, however it is possible there are other incompatibilities that slows it down - ie. the Dash charger won't provide the full 10W for some reason. A possibility might be the Dash charger cable, as from what I understand this is a bit different to a normal cable to support the Dash charging technology. Maybe try a high-quality standard USB and see if it charges any faster?
An aside: The S8/S8+ is the fact it can also fast charge over (the non-proprietary) USB Type C with 5V at 3A (also 15W). This isn't USB Power Delivery (USB-PD), just the 15W allowed by USB Type C, and since that can provide the full 15W the phone can use over QC2 there's no actual need for USB-PD - but most charges that support 5V at 3A are labelled as providing USB-PD and will work with the phone even if the phone don't use the 'PD' part of the spec.

So... how it is with the charging, exactly? -- USB-C and wireless charging question

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

Wireless Charger Pad Slim EP-P1100 Isn't it fast charge?

Guys, I bought this Wireless Charger Pad Slim EP-P1100T, to use on my Note 10 Plus, the information says it has a fast charge, but when I put my device on it, fast charge information does not appear even though it is enabled on the cell phone, is it really so? Android 10 does not show the message?
I think you should use Quick charge 3.0 charging head not the samsung 25w head with it , anyway even if you use the suitable charger with it Note 10 plus automatically shut off fast wireless charging when using slim pad for more that 20% of fast charging because of heat issues since slim charging pads don't have cooling fans and they heat up very quickly
I have one of these also, the only fast charger that enables fast charge with that wireless charger is my old Note 9 charger, it provides the 18w QC2.0 the wireless charger needs.

I'm using the charger that came with Note 10 + ...
Is that why the phone doesn't charge fast charge with the pad?

Yes, this charger was designed for the previous generation of phones (S9, Note9 ect) which included a compatible charger. Samsung confirms this here: https://www.samsung.com/us/mobile/m...nes/wireless-charger-pad-slim-ep-p1100bbegww/
Samsung doesn't use Quick Charge technology since it's a Qualcomm only feature and Samsung uses its own chipset which isn't Snapdragon.
Instead, it uses Power Delivery which is a standard and better in all aspects.

That's not entirely true, Samsung definitely do sell phones with the Qualcomm Snapdragon SOC and the 15W charging on most of their previous phones (S6, S7, S8 and S9 generations) was QC2.0 or QC2.0 compatible. This is why I am able to fast charge my Exynos Note 9 at full 15W with a QC3.0 charger.
USB Power Delivery is good but it's just another charging protocol, later versions of Qualcomm Quick Charge are also USB-PD compatible.

That's right it is, but there's more.
It's not just an other charging protocol, it's an USB standard, that's means all USB ports will have it by default.
Quick charge is proprietary licensed and will be dead soon because there's no use of paying licence for nothing.
And it's not the same at all. Power Delivery is made for dynamically adjusting current intensity and tension depending of the device you plug in and battery level, for them to take only what it needs.
Quick charge isn't, that's why you need dedicated QC ports on chargers.
It's easy for QC to be "compliant" if it shares one similar spec, but it's useless since all next USB ports will use USB-PD.
And that how it worked before, with fast charging, you only had to take in consideration that the output specs and the chargers is equal or higher to the input specs of the battery to get fast charge, but it's risky for the battery.
It may appear silly, but for efficiency and durability, lithium ion battery should not be charged at the same current and intensity at all levels and that's at least one reason why it's important.

I disagree but there doesn't seem to be any point in telling you that you're wrong.
