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.

Method:
First I used my phone until the battery was below 15% in order to get a better picture of what the charging would look like over almost a full battery cycle. I did not start at the same battery percentage for each test because I did not find any benefit to doing so. I original did this for uniformity, but it did not make a difference after trying it using the more accurate equipment.
I then cleared my history in the Battery Monitor Pro Widget (BMW Pro) recording app which was used to log the battery [mV], battery temperature [F], time, and battery percentage changes. Once this was done I plugged in my USB Power Monitor, turned airplane mode on, removed the case, and let the phone charge. I started logging the data via my power monitor once the phone showed it was charging. From this point onward I let the phone charge without interrupting it until it reached 100%, then I let it charge for another 10-60 minutes to see if it was still drawing power from each charger. Once all of this was done, I exported my data collected from BMW Pro, emailed it to myself, and pasted it along with the USB Power Monitor data into an Excel spreadsheet. All of the data was then delimited to separate the clusters of data due to the way they were recorded, and subsequently graphed. The USB Power Monitor recorded data points every 0.36 seconds, while the BMW Pro took recordings every 5 seconds because I was having issues with the “real-time” recording option in the app working correctly.
All of the data was then graphed into the nice figures you will see below; each color reflects the same variable across all of the graphs to make reading them easier. I included a legend at the top of each set of graphs which should also help make it easier to read the data.
Equipment:
These tests were conducted using a series of different chargers. The same brand was used for both Quick Charge 2.0/3.0 tests to minimize experimental error; This trend remained the same was also done for the wireless charging tests
Wall Chargers:
Quick Charge 2.0: Tronsmart 18W charger 5V/2A, 9V/2A, 12V/1.5A
Quick Charge 3.0: Tronsmart 18W charger 3.6-6.5V/3A, 6.5-9V/2A, 9-12V/1.5A
Cable(s):

I like your Tests. But why do you measure all 5 Minutes?
The App BatteryLog Records state every time the % changes.
Sadly the Bluetooth Module on my usb Powermeter broke off. So I have to get this repaired first before I can do any charging Benchmarks

I can add an actual plot of it too if you would like. I am going to conduct a test using QC 2.0 to see how it consists to QC 3.0 maybe tonight if I get a chance. If there's s anything you would like to see let me but know.
I'm not sure is this is accounted for but I've noticed this is the first phone I've had that I can remember having the battery percentage seem accurate. My G3 would hit 100% but if I left it on the charger an hour past that, I got more out of my "100%". I would at times get 30 mins SoT on 100% but then 3 mins per afterwards. My HTC 10 actually seems to drain evenly throughout the 3000mAh which means while a G3 may read 100%, it's actually at 91%. Other phones could have inaccurate percentage reporting which make for a greater perceived charging speed.

Since you've done a lot of charging, are chargers with QC 3.0 supposed to read "Charging Rapidly"? My QC 3.0 car charger didn't say "Charging Rapidly" with USB C to C and I'm wondering if I need to send it back. It did charge mighty fast though.

Well what charger were you using? If the charger doesn't support QC 2.0/3.0 from the Type-C port and instead uses the Type-C standard (5V/3A) that the Nexus 5X/6P use, then it won't fast charge. I never look at what the phone says because its irrelevant so I use a multimeter instead. The only downside to that is that no C-C multimeter's exist yet. The phone can only support 1 charging standard at a time, so that means it either supports Quick Charge 1.0/2.0/3.0 or Type-C fast charging not both. That is why is will charge slower over a C-C cable unless the Type-C port on the charger supports Quick Charge from Qualcomm not the USB standard version.

The Aukey 3 port car charger and it says the USB-C port is QC 3.0. Guess I should assume it's actually doing what it's supposed to since it charges stupid fast.

On Topic: Those numbers for the HTC 10 QC 2.0 vs 3.0 are very interesting. Looks like QC 3.0 is definitely more efficient. And I assume changes in voltage are it monitoring temps and trying to keep them down. This is all new to me so I'm learning.

It should charge at QC 3.0 speeds from my understanding. I have a Tronsmart wall charger that supports QC 3.0 over type-c, so I can test it when I get a chance.
I am redoing both tests with the same brand of charger since I used the stock HTC charger for the 3.0 and a Choetech one for the 2.0 test. I will be using Tronsmart chargers for each of the new tests, and I will post them up with the old ones. The QC 3.0 does really keep the heat down that much, because if it did the current and voltage could be much closer to the 18W it seems to support on this phone. QC 2.0 seems more consistent and maintains its output longer before tapering off which can be a bad or good thing. I might download an app to verify my results and to see the temperature, but I don't know how well that will work and or if it will affect the charging times.
I'm trying to use my Samsung Fast adaptive charger with my Wife's M8, but it doesn't seem to quick charge it? On the S6 it has a "fast charging" notification but nothing like that on hte M8. Is that normal? The total charge time from 1% to 100% on the M8 is 3 hours. Again, is this correct, especially since I'm using a quick charger?
Samsung's fast charge technology is proprietary, and only works on Samsung devices.
The M8 uses the Qualcomm proprietary "Quick Charge 2.0" technology. It requires a changer that is branded QC 2.0, either saying Quick Charge 2.0, or with the circle/lightning bolt symbol as shown here.
Don't know where you are located, but you can get a decent QC2.0 compatible charger on places like Amazon (just search "Quick Charge 2.0" and you'll get plenty of results) for $10-12 US.
Once connected, Quick Charge 2.0 won't actually give you any indication on-screen that its charging any faster (like the Samsung notification you mentioned) just the usual charging indicator. But you'll find the phone charging to full in around an hour or 1.5 hours.
You can "thank" the manufacturers for the lack of standardization with quick/fast charging. Technically, any device with a Snapdragon 820 chipset can support the Qualcomm QC 2.0 feature and chargers (unless the manufacturer messes with the feature). But some manufacturers (Samsung, and more recently OnePlus) decided they can do it better; or at least force you to use their brand chargers.
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.

15mins with either charger yields about 15%, no noticible difference. Seems like the oem charger throttles when screen is on.

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

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.

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.

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.

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.
I haven't seen this mentioned at all or not sure if the s8 supported qc 3.0 or Power delivery but does the S9 support QC 4.0 or 4.0+ or even qc 3.0 or Power Delivery like the Pixels?
According to GSM Arena, only Quick Charge 2.0 is supported...

QC 2.0 in a 2018 flagship phone is blasphemy.
Apparently USB-PD is also supported but is throttled.
Seems like samsung is treading lightly when it comes to battery, who could blame them.
The Note 8 supports Power Delivery, so I assume the S9 will as well.

While I see that it only is rated for 2.0, I've gotten used to 3.0 with my LG phone. The G6 charges fairly quickly. I would miss the fast charging speeds if it isn't as fast as the LG.
I'm looking forward to any fast charging aspect since my current phone doesn't have any of those features. Since Apple hasn't "invented" it yet...

Oh yes... my bad forgot they do have that function, just with the included accessories it still doesn't "fast charge" because apple wants you to purchase the $30-50 cable or wall charger to make it happen.
I noticed that charging takes around 30mins longer on my s9 compared to my s7. I'm not sure if that's because it might have a bigger battery or they've purposely slowed down charging to prevent an explosion lol. The phone doesn't seem to heat up while charging like it did with my s7.

It does have the same battery size. Nice that it doesn't heat up the phone.
By chance where you using the phone while it was charging? It will kick it from quick charge to standard charge if the display is on.

True...ish.
I use Anker's 30w charger (and I do use Apple's USB-C to Lightning cable). It wasn't that big of a deal for me because I needed a new work/travel charger setup anyway.

Nope I leave it since I'm aware of that limitation. I prefer the phone to heat up tbh and charge 30mins quicker!

No, it is not. Not even my S7 Edge did that. Fast Charge stays regardles if you have the display on or of, if you're using the phone or not. I heard (but not confirmed tho) that this happens during WIRELESS CHARGING. This I don't know and cannot say if it is true or not. But the fast charge with the original Samsung wall charger will not switch from "fast" to "normal" unless it's an issue
When fast charging my charge voltage wont go above 7.5v when the QC2 spec alows 9v and 12v.
There was annoying sound coming out from the usb port of the S9+ when i plugged the device using Anker QC3 charger.

Curious to hear other experiences, but my T-Mobile S9+ is very erratic with PD support. Using Anker's latest five port charger with PD, my S9+ will start indicating "fast charging", but will always drop back to "cable charging" at a very slow speed. Hmm.

On my S7, and I'm pretty sure the Edge uses the same charging technology, it'll switch from [email protected],6A=~15W to [email protected]=~5W after I turn on the display, just because it says fast charging that doesn't mean it's actually doing that. Have you tried it yourself using a USB power meter ?
When it switches, the notification also change from "fast charging" to "cable charging" or something like this.
If it is still displaying "fast charge" I really doubt that Samsung would charge it normally. More than that, it would be something everybody will brag about and be a well known issue and it is the first time I hear about it. For wireless charging yes, I heard this...but never for cable charging.

There are results when you google it, for the S7 and S8, I guess it's not that big of a deal because it displays "fast charging" and because people expect the phone to charge slower when active. Fast charging while being used was also the big selling point for "Dash charge" the fast charging tech from OnePlus.
It also says so in the manual on Page 12 :"You cannot use the fast charging feature when the screen is turned on. Turn off the screen to increase the charging speed" http://downloadcenter.samsung.com/c...G935_UM_EU_Marshmallow_Eng_Rev.1.0_160219.pdf
But to see it with your own eyes, just get yourself a cheap USB power meter and measure it
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.
