I'm having problems charging my H815 using car USB chargers. One of three things usually happens:
1. A message pops up saying that a charger is connected, but the phone does not charge at all (no red LED, and Ampere reports that the battery is discharging)
OR
2. The phone starts charging, sometimes with a current as high as 1000ma, but then stops charging after a minute or so
OR
3. The phone charges, but only with a current of < 300ma (even when connected to the 2.1A output on the charger.
This happens when the phone is at various levels of charge - e.g. yesterday is was at 59% and would not charge. Today is was at 79% and the same thing. I've tried 3 different cables, all of which deliver >1000ma to the phone when used with a mains wall charger.
The charger I've been using is this one:
https://www.amazon.co.uk/EasyAcc®-A...dp/B00N4JZP36?ie=UTF8&ref_=pe_931411_45466481
I also purchased and tried this charger, which claims to offer a quick charge feature, but it too only charges at a maximum current of 290ma:
https://www.amazon.co.uk/dp/B015O67W96/ref=pe_1909131_77697001_tnp_email_TE_AMZLdp_1
The car is a Honda S2000 (2002 model).
Has anyone else had problems with car charging?
I use to have a problem like this. Standart car chargers was not charge even plugged in all day long, if I use GPS or playing music etc on my phone while driving. I try every good brand like Energizer etc. with 1.8 Ampere or 2.1 Ampere power output.
Qualcomm Quick Charge technology solving this problem and it could decrease charge time %70
LG G4 has snapdragon processor and snapdragon processors compatible with "Quick charge" technology. You can buy "Quick Charge v2.0" supported car charger and it could be help.
LG G4 supported Quick Charge v2.0, LG G5 supported Quick charge v3.0. you can get more information if you google it
For example Aukey branded car chargers licenced by Qualcomm and supported "Quick Charge" technology.
You can search the product on amazon. (a Quick charge v2.0 supported charger about $12-$13)
I'm using this product and my mobile phone charging quickly even I use GPS assisted map application while driving.

Thanks for your reply. I've managed to find a Tronsmart Quick Charge 3.0 charger so have ordered it and will give it a try.
Is it possible?
I don't think so, no one has done it AFAIK. It would probably require some rom or kernel modifying. Why would you even need to disable it?
You could use a simple two wire usb cable that's incapable of sending data - this way device and the charger can't do a handshake and it should display "slow charge" on the phone.
You looking to limit charging speed and temps (to prolong long term battery life), or something like that?
Quick Charge (QC) is massively useful IMO. Such as getting on a plane, and need to top off quickly at the gate. Benefits outweigh the theoretical consequences. Battery life decline is hyped way more than it should be, in real life usage (looking at you, Apple!). I've had a number of smartphone and tablets which I used for 2-3 years with no noticeable decline in battery life (even using Quick Charge).
If you don't want QC, just use a charger that doesn't support QC. The stock charger that came with the M8 was a standard one (no QC).

Isn't the stock M8 5V 1.5A charger actually quick charge 1.0?(at least the european variant afaik)
Some chargers I've used made the phone display a "slow charge" popup, so the original one seems to be faster. Then again - I've used a 2013 samsung feature phone charger and it was "fast charging" so not 100% sure.

AFAIK, only standard (no QC) chargers were shipped with all M8 versions, at least at original release. I remember from reviews and folks complaining that the phone supported QC2.0, but did not ship with a QC charger. And you had to pay for a QC charger as a separate accessory. Now, there are many versions, and a pretty long time period when these devices were sold from HTC. So it's possible at some point (or for some versions) they did ship a QC compliant charger. But I don't think I remember hearing of that happening (but again, it's possible).
The charger is only compliant with QC if it actually says "Quickcharge" (1.0, 2.0, etc.), "QC" or has the QC lightning bolt/circle logo like they show here: https://www.qualcomm.com/solutions/mobile-computing/features/quick-charge
Far as I've seen, only these "QC compliant" chargers will work with Quick Charge (actually charge the phone faster than the "stock" charger).
Case in point, I bought a QC2.0 car charger, and it charges almost double the rate of the "stock" HTC charger included with the M8.

Not 100% either, but I think the "slow charging" message means less than even the intended "stock" (non-QC) charger. Basically, an inferior or otherwise lower output (amps) charger.
Now, when you say "fast charging" are you sure it was actually "Quick Charging" or that it just didn't say "slow charging"? From what I can recall (don't use the M8 as my daily driver anymore) the phone will just say either "slow charging" or "charging" and there is no on-screen differentiation between "normal" charging and "Quick Charge". The only way of telling if QC is working, is that it charges much faster (battery % rises almost double the rate).
So basically, my understanding is that there are 3 conditions: slow charging, "normal" charging, and Quick Charging. But the on-screen message will only tell you of 2 conditions: either slow or normal/QC - with no differentiation between normal and QC.
Samsung "fast charge" is proprietary, and doesn't comply with Qualcomm Quick Charge. There have been numerous reports of Sammy "fast chargers" not working with Quick Charge. Which makes sense, since my understanding (as mentioned above) is that only QC branded/licensed chargers will work with Quick Charge. Never actually seen a Sammy charger working on this phone with Quick Charge. But again, just because I haven't seen it, doesn't mean it hasn't happened. It would help if the phone manufacturers could stick with standards, instead of insisting on developing proprietary crap, and confusing all of us!

Checked mine, no logo or "quickcharge" text. Also I've found no info anywhere that it's quickcharge capable, so it seems it's a normal charger, just a bit more powerful.

Out of curiosity I've checked what the phone displays when charging using a properly working usb cable and a simple power-only one, both on the stock charger brick.
On stock rom lock screen it shows "charging" on the bottom on both, but with addition of "slow charge" notification on the latter.
RR 5.8.5 shows "charging rapidly" and 1600mA and 9.0V - very likely just a set text as voltage is false and nothing changes. Using power-only cable it's "charging slowly" with 500mA and 9.0V - same thing.
So it is as you said - two types of message for either "much less than normal" and "normal or more"

The old Samsung feature phone charger is 4.75V and 0.55A, yet for some reason M8 decides to put in on par with it's own 5V 1.5A charger and say they're both "normal" when charging, weird.
But I agree with you - all those different technologies confuse and prevent us from having just one power brick to rule them all fully work on many devices - there's Samsung Adaptive Fast Charging, Huawei Supercharge, OnePlus Dash Charge, Motorola TurboPower, Oppo Vooc , MediaTek Pump Express and maybe even more. Good thing that at least any phone can get charged using any brick - faster or slower, anything is good in an emergency.
At least it's not as bad as it was back in time, when every phone manufacturer had a different charging plug - can't forget those Sony Ericsson plastic things that used to break off.
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?

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.
hello , can i use samsung s6 charger for fast charging on my htc m8 ?
Unfortunately, no. It has to be a charger which bears the Qualcomm Quick Charge logo like this: https://goo.gl/images/vZLCZB
Either the lightning bolt symbol, or the charger will say "Quick Charge 2.0" etc. on it.
The M8 specifically supports QC 2.0, although other official QC chargers will work, to some degree. QC 3 and 4 chargers will charge at QC 2.0 speed (not as fast as QC 3 and 4). A QC1 charger will work (faster than standard charger), but not as fast as QC 2.0 speed.
Unfortunately, Samsung uses their own fast charge technology, which isn't compatible with other brand devices (such as HTC). Blame it on the phone manufacturers, who are trying to differentiate their products with their own fast charge technologies. Breaking the native Qualcomm Quick Charge function, even for devices (such as Samsung, and there are others) that use Qualcomm Snapdragon chipsets.
it doesn't have this
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.

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.
