Hello,
I've just got an M9 and am happy with it. Thought I'd make the most of the quick charge tech so I brought a QC2.0 charger from amazon:
An Aukey Quick Charge 2.0 42W 3 Ports USB Desktop Charging Station [sorry, can't post links yet]
Reading the reviews, and also other threads on here, that people with M9's using QC charge very fast but mine just isn't.
Right now it's taken just oven an hour to charge to full from 49%. Nothing like what other people are saying.
I've contacted the supplier of the charger and they've just sent me another one but it's exactly the same. How should I continue testing? How would I determine if it is the Phone?
The only issue I can potentially identify is that after around 75%-80% the rate of charge seems to drastically drop off.
Any insight would be great !

Are you stock? if not what rom and kernel are you using?
regarding the drop off after 80% thats perfectly normal for QC, it will be quite rapid up until about 80+% then sort of trickle.

Pre - 80% its charging about 1%/minute. Which seems much slower than other people describe.
Post - 80% its about 0.3%/minute
Did it come with a USB cable, and are you using that one? In order to take full advantage of quick charging, heavier gauge and/or short cables are best. And yes, the closer to 100%, the less difference in charging rate.

Hello,
Yes it came with a cable which was high quality, which I'm also using.
I did have a thought if it was because I was charging it with the phone turn on, but just did a test with it turned off and the results were very similar
Are you using the QC 2.0 port? Because that thing has only one.
I'm always using official chargers, same for my M9..works very well.

Hi, Yes using the correct Orange QC port on this charger.
Perhaps you could share what sort of charging times you're getting with your official charger?
Also worth adding there may be an 'offical' HTC charger but all that should matter is if it's Qualcomm QC2 licence device, which it is and is listed on the Qualcomm website
So I'm back to my original question, how can I tell if its the phone?
It would also be good if anyone with an M9 and QC2 could post their charging times
Thanks

Something else to try would be disabling HTC's car app as it causes issues with charging. Open the car app>go to settings>disable all settings.
Go to phone settings>apps>car>uninstall updates>disable.
I use a Choetech 60W Quick Charge 2.0 for mains, and a Choetech 51W Quick Charge 2.0 Car Charger for the car. The car one is ideal because it has a blue LED for normal power which changes to green when it's using Quick Charge, to give you an indicator it's working.
I get between 1% and 2% charge a minute depending on how hot the battery is and what is running (Viper 4.0.1 ROM - Android M). Usually around an hour and half for a full charge.
Yours doesn't seem excessively slow - make sure you try when your battery isn't hot and when no apps are running in the background. Maybe useful to run the Ampere app to see what the current battery drain is before you start... ideally should be 200ma or less.
Drop off after 80% is normal, ~1% every 2 minutes.

I had the same problem initially with my QC2.0 chargers, finally found out the cables(including the one packaged with the charger) were not up to the task........eventually started getting slow charge warnings.
I use these: http://www.amazon.ca/gp/product/B013DOCZAC?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
Haven't had a problem since
QC is only effective up to 80%, after that it will slow down so as not to cook the battery. This isn't just QC2.0, this is all forms of quick charging. Lithium based batteries must be very carefully charged as overcharging will lead to devices exploding. Just ask the hoverboard manufactures. As such the charge speed slows down after about 80% capacity. To further confuse things, a battery does not have a physical capacity like a gas tank or other physical holding device. Things like load, temperature, and age all change the available capacity. Capacity %, much like signal strength bars, is simply an estimation done with unknown calculations by the phone vendors. If you really want to know what's going on with your battery, you have to get an app like GSam Battery Monitor that will show you the current voltage of the battery and the charge/discharge rate in milliamps.
I'm using the same charger and it charges from 5% to 100 in 1hr and 20mins

One issue bothers me a lot. I cannot use the phone for navigation for more than 2 hours even with car charger connected. In about 2 hours, it drains out fully. My latest theory is that after about 30 mins of charging, the battery starts heating up, and so it stops charging.

I am not 100% sure in terms of the amperage. But I tried with a car charger capable of charging a laptop, using the wall charger and cable which came with the phone. I was sitting in the passenger seat, phone was in my lap (not mounted in windshield) and Google Maps was running in navigation mode. For the first 15 minutes or so, I saw that the phone was charging. The charge level increased by 1% or 2%. After I think 20 minutes, it stopped charging. CPU-Z app was showing battery status as
health: over heated or heated (don't remember clearly the text)
power source: connected
status: not charging or discharing
Phone's back was very hot. I unplugged the USB cable and connected it back, and it started charging again! I waited for it to cool down, removed the phone case, repeated this and got the same result.
This is why I believe the phone is doing something to protect it from over heating. I am not sure though.

Amperage is important son too little it will discharge, I think it will limit if too much. Nav can cause some heat for some of these guys but I've never heard of it getting that high my guess is something was wrong.

I have gotten my last few chargers at Sam's Club, they are about $10, and are rated at [email protected]
In an older phone I had a similar issue where my phone would overheat and not charge properly, once I got a new charger I cut the end off the old one and read the voltage with a meter, it was putting out almost 7.1v (should be 4.75-5.25vDC for USB 1.0-2.0 standard, and 5.25-5.75vDC for USB 3.0), pretty sure that is what caused it... cheap components equals cheap quality and flaws. Current rating should be irrelevant, as long as it meets the devices minimum requirements (most modern phones are [email protected]), even if a charger is rated at 2, 3, or even 5 amps, the device should not draw more than it can handle. Current is drawn, not pushed, a device will draw the needed current at the expected voltage, you can't really "over-current" a device by using a power source that is rated at the proper voltage but a higher current. Similar instance can occur by using a charger that has too low of a current rating, the device will try to draw more current than the adapter is rated at and the adapter will eventually fail or fall out of specifications.
Some other good chargers are by Anker, PowerGen, or RAVPower, and of course a Samsung branded adapter will work well, most all of these can be purchased for $8-$15 on Amazon. If the adapter is not rated with a current rating, then skip it, it is probably only 600ma-750ma and will be more headache than it's worth in the long run.

The Skyrocket (and several other Samsung phones) need special "type 2" chargers. Apple charges are type 6, so if it says compatible with Apple, don't use it as it may not work. If the two center pins on the USB port doesn't have a 50 ohm resistor across them (or not shorted) , the Skyrocket will only draw 350 mA. Samsung and older Curve BlackBerry chargers have the resistor. At 350 mA, the phone draws more than the charger is providing, and the charger circuitry heats up trying to keep up with demand.
Jrockttu has a great thread under General called "Fix your Skyrockets battery life"
I've MOD'd all of my chargers, now my phone is happy with the screen on all day while driving and it stays charged, or charges slowly...

To eliminate the possibilities mentioned above, I bought the following:
1. Car Charger: PowerGen Black 3.6Amps / 18W Dual USB Car charger
2. USB Cable: Mediabridge USB Charging Cable
I also installed this app (Skyrocket Charger Info).
Summary of what happened:
With new car charger: Fast Charge (A/C) - Charging at 898 ma
With old car charger: Charger Wakelock - Charging at 497 ma
When connected to mains using factory charger: Fast Charge (A/C) - Charging at 898 ma
When connected to PC USB port: Slow Charge (USB) - Charging at 497 ma
Even with this new charger, phone stops charging once it heats up.
The full story:
Once I plugged in the phone to the new car charger using the new USB cable, the app showed the charging current as "Fast Charge - Charging at 898 ma". This is the same mA value it shows when I plugin into the mains with the phone's factory charger. I drove around with maps for around 15 minutes. Once I stopped, I saw that charge level had dropped by around 9%. I immediately launched CPU-Z app. It was showing battery overheated & not charging (see attachment 1). The phone was hot.
I removed the charger. After I think 1 minute, the battery status became 'good'. I plugged in the charger again. It started charging. While I was looking at the CPU-Z screen, battery status changed from 'good' to 'overheated' and 'charging' to 'not charging'.
Attachments:
(Please note that these screenshots are from another test where I had driven for around 30 minutes, and is not based on the above story.)
1. Phone state once I stopped the car. Charger is connected, but phone is not charging. Note that ignition is on.
2. After removing the charger.
3. After connecting the charger again. Within a few seconds of taking this screenshot, it changed to what is shown in attachment 1.
So I guess I can't do much about this, right?
I can't remember if you replaced the battery or not.... That could also be any issue if it's getting old and can't absorb the charge as fast as it used to... It will heat up quicker.

My phone and battery are now 18 months old. When I am in office, I charge it twice. It doesn't drain much, but I keep it fully charged just before leaving office.
Phone can overheat when under direct sunlight with GPS, screen and CPU working (the most power-consuming activity on the phone happens to be navigation), and also charging. Nothing unusual in that - its internal temperature in this case can reach beyond 100 degrees C. The battery can't charge when above 60-70 degrees C, because it can get physically damaged or even explode.
Concealing the phone from direct sunlight might work.
Limiting the CPU frequency might work.
A new battery might work.
Hello there,
I decided to open this thread as I've now had a bunch of issues with the stock charger that came with the device and it would be interesting to know if there's anyone else who's having this type of issues.
The exact issues that I've been having with the stock charger seems to be that the charger doesn't output enough of a amperage for the tablet to hold charge while in use, and even when it's not in use it takes almost 7-8 hours to charge from 50% up to 100%. It's as slow as if I would charge it from a regular USB port, if not, even slower and I don't really know why exactly this happens as it says that it's charging from AC adapter in settings.
To comfirm my issue was not related to the tablet itself, I used another charger that's rated at similar specs to the stock charger (2.1A) but with the same Micro-Usb cable that came with the tab. With that charger, it charged up from 50% extremely fast (around 1,5 hour) and I could even use the tablet while charging without any battery drops. So that comfirms two things, it's not related to the tablet or data cable but to the actual charger itself.
Anyone else that's been having this type of issues with the stock charger?
My tab needs max. about 3 hours to charge full and imo it's ok. Tried charging during Half Life2 gaming and can confirm that there's not a lot of charging going on, maybe 1or 2% in an hour. But that's ok for me, as long as it doesn't start to get emty while charging during gaming.
The charger is defective or don't bring enough power to the unit. I also get negative charge while playing high end games an also increase when i am, on Optimized mode. Many others has reported this situation on GeForce forums but nVidia is quiet about it.

I get negative charge even when doing basic tasks like listen to music or watch a video with the stock charger, so I guess my charger is faulty. I've already reported the issue to Amazon and they gave me a 50GBP partial refund (80 USD!) because of the faulty charger without having to ship anything back.
I just find it odd that theres many people that have the issue and nvidia doesn't seem to do anything about it either!

My guess is that a faulty cable or the charger itself is causing D+ and D- to not be shorted together by the charger, resulting in the tablet thinking it's charging from a USB port instead of a dedicated charger.
Does device status report charging state as Charging (USB) instead of Charging (AC)?
I admit I never even unwrapped the stock charger, I've got one of those nice Anker 40W 5-port chargers along with a bunch of 24/28AWG MicroUSB cables from Monoprice.

The charger appears as AC in settings, so it should be charging faster than it does.
I'm using a charger similar to what you use right now, a Dodocool 4 port charger that works great! However, I'm using the stock cable.
First make sure you are using stock charger and cable.
If you see discharge during non intensive activities you may have a defective charger. Nvidia has rma'd the charger by itself for people.
I have the same issue but my charging time is a bit better 3-4 hours. But what is really annoying that it makes a lot of electrical noise. I have a lot of things that I charge, but I have never heard this so load earlier. Its coming from the adapter, I can cleary hear from 3m. Anybody has similar issue? I try to record the sound, and send to nvidia. Maybe they will react.

I can confirm that this combo works a treat for my NST. I use it to simultaneously charge my G3, NST, N7 and some small LiPos. Fast charge.
Sorry to dig up this thread but I've had the same issue and i was WTF-ing like crazy until i switch the USB cable to a charging cable i got from a power bank... The charge time dropped from 6-7 hours to 2-3 hours. I'm not sure why, perhaps my cable is faulty or perhaps it was meant to charge like this, or perhaps it is supposed to be used to connect a controller only (both ends seem to have a controller icon on them)?

It's not due to the MicroUSB cable but due to a wallwart that's messing up the amperage I believe, as I've used the MicroUSB cable with other wallwarts and it charges normally then

You are correct. I charged the tablet at home 2 times this weekend and it's definitely an issue with the charger as it sometimes charges properly and sometimes it does not.

Contact amazon and tell them exactly about the issue, they'll compensate you for it probably. I got 50£ back from Amazon.co.uk for the broken charger, which is quite a bit of money.

Thanks for the tip, i'll give that a try
Well, same thing here. Just noticed it while using Skype. Battery dropped from 100% to 95% pretty quickly while charging.
I'm going to ask Amazon for another charger or compensation.
I have a 2.4A charger and still battery no good.
I lose around 2% per min of battery charge while idling with battery saving features on (2 cores shut off, CPU frequency set at 50% and Framerate locked at 30FPS) when ingame the battery drops 2-3 times faster. takes 2 hours to charge from 97% to 100% and 2 mins to lose that charge. I think I bought a Tablet that has a faulty battery as this is not acceptable. My tablet is unusable as the battery takes a couple of mins to lose 3% of charge and a couple of hours to regain the 3% charge only to lose that charge (and then some) when I try to use the tablet.
Find a fast charger, any recommended?
Stock from HTC direct (Digital River) works well.

I just got one of those too, and it's great. Wish it wasn't so big, but it does the job.
I just picked up a couple of Anker dual-USB wall chargers. They have higher amperage (2.4A) than most standard chargers and on both USB ports simultaneously (many dual-USB chargers lower the output when both ports are in use). Between the better charging times, the dual ports and the build quality, I'm very satisfied.
The Anker charger with Qualcomm Quick Charge tech looks even better, but I don't have any experience with it personally.
Show me the link and experience, thanks!

i have the htc rapid charger 2.0 and the aukey rapid charger (+the 10000mah external battery quick charge)
both work really well. if i knew about the aukey. i woulda originally gone for that first
Quick review of the Keedox Quick charger 2.0:
Well it has the official logo of Qualcomm Quick charger 2.0 printed on it but I kinda find it as slow as the stock charger from hTC :crying:
Tested from 45% to 100%
Till 80% it's amazingly fast with 20% every 10min but once over 80% it's slowing down, from 90% to 100% it's extremely slow like 1% every 5 mins
It took 75 mins to charge these 65% while it's supposed to charge from 10% to 100% in an hour (80%)
So we are pretty far from the advertised +70% faster charger.
Take in consideration that I am using Viperom 2.2 for the time being based on 1.40, these Roms are known to have bugs with charging time, so I am waiting for the upcoming Leedroid based on OTA 1.40 Rom to be sure this charger is crap and give a negative review on Amazon.
I am still waiting for my TechMatte car quick charger, my sis still didn't finish to empty her 2 suitcases, girls...
I don't think it's a matter of cable, I am using the same USB 2.0 cable that I used back with the Quick charger of the S6 on the S6, it was charging the S6 from 20 to 100% in 50 mins.

The Aukey quick charger I have does the same type of throttling thing once it gets around that 85% mark. I haven't paid enough attention to my Droid Turbo charger to see if it does the same thing. I figured it was just a safety feature of the Aukey charger.

So these are quick charger only from 0 to 85% !! The S6 stock charger on S6 was also slowing down at 85% but it wasn't that slow, the results were certainly faster.
Again I can't give a definitive conclusion about the Keedox before I try a stable rom based on the official latest OTA

The slowdown at ~80% full is the expected behavior to be easy on the battery. I find the quick charge most valuable when I am about to leave home and I can use the last remaining minutes to cram some juice into the battery. Main charging happens overnight for me without any need to hurry.
The slowdown >90% is behavior I have seen on every phone I have ever owned. It is a safety feature to avoid overcharging the battery. Overcharged li-ion batteries have been known to explode and catch fire, after all.
It may simply be that HTC is more conservative with its batteries than Samsung is.

Hmm ...
Now this makes sense ... Now I get why my charger works lil slower above 85% ...
Updated Viper Rom to 2.3, the Keedox charged my M9 from 34% to 94% in a matter of 35 mins
Thanks!
It looks like the htc m9 is slow with quick charger 2.0 anyway, gsmarena posted a 2h charging time for 0 to 100%.
So my Keedox is not bad after all

Hi. Posted this in a couple other places already. Got my XZ yesterday and it doesn't come with a quick charger. Fine, I bought some. None of them are working though.
Tried Anker and Aukey, and also the charger from my wife's HTC 10. Any ideas why this isn't working?
Everything I've read (the specs on the official site) say that this phone supports Quick Charge. I've tested the HTC 10 in all 3 chargers and it quick charges so I know it's not them.
Tried it with Battery Care off and nothing. When Battery Care is on all I get is messages saying "Battery Care has crashed" or something. Pretty annoying, considering I just dropped about £50 on new chargers!

Sony enable Quick Charge only when battery is under 60% for safety reason.

Battery was at 15% dude.
When it's quick charging, does it give any indication? I know the HTC 10 says "charging rapidly".

There is no indication.
You can check with Ampere.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
This app doesn't show exact charging current, but if it shows over 2,000 mAh (wait about 30 sec) quick charge is working.
Please note there are heat throttling, so quick charge is disabled when device is really hot.
I bought Aukey QC 3.0 and when the phone is over 85%, I get 680ma; below that I get higher rates over 1000ma.
UPDATE: I put my phone in charge at 50% and I got over 2000ma but when it reached 80%, it changed to 600ma. So it supports quick charging but when it reaches to almost full, it activate battery optimization for the safety of the battery.
confirming above, I also came from a HTC10 and was expecting to see a "charging rapidly" message. My XZ also doesnt display this.
When using GSAM, I can see the rate of change of charge, when connected to a QC2.0 or a QC 3.0 charger and at low battery capacity, I can see rate of change of up to 60% per hour, this is in line with my other QC phones. It does appear that Sony throttles charge speeds more than HTC does above 80%, but I can understand that, and it doesnt bother me too much.
Yeah, I've had some time to look at Ampere and would conclude the same.
My XZ on the Anker charger is peaking about 2190ma when charging at a low percent, whereas my Z2 on the old standard charger peaks around 730ma - this is after 5 minutes for both.
Was just a little freaked that it didn't indicate that it was "charging rapidly". Guessing the throttling will also help battery life, although it was a bit of a sore one seeing the wife's HTC 10 peak around 2900ma.
Anyone know if the Galaxy s7 chargers will output 3.0 with the international models??
Did you buy a used phone? My XZ came with an OEM SONY QC 3.0 rated charger. Using Gsam battery monitor pro I get readings up to 2200+ mAh charge rates between 30 and 60% battery. That is generally considered to be the safest range to fast charge lithium ion batteries (fast charge generally being a charge rate higher than .5C, which for this phone is 1450mAh). I don't get any indication it is fast charging, it just does it. QC 3.0 applies a varying voltage and amperage throughout the charge, offering more gradual and "healthy" charge curves as opposed to conventional or QC 2.0 charging. Basically your QC 3.0 charger charges the battery as fast as is possible while not sacrificing battery life (say due to excess heat or overcharging).
Hi, I have recently bought a new XZ & bought the original Sony charger UCH12W at same time. The hour of charged is need approx. 2 hours from the battery percentage 30% to 100%. Is that any one face this ? Or maybe is my charger or either my phone problem.
Try this
Use the the detect usb in the notification keys before connecting the charger,, this will solve the fast recharging issues,, even if phone will recognice charging after few seconds,, charging will be fast and normal

this solves the problem, its sad that you need to do this first and its not automatically fast charging .
Still buggy
Its the only method that i find it working,,, but still there is a chance that phone still wont charge fast so keep an eye on the charging process,, and its temporary solution till next update for soctware as i hope its a bug in android 7
I have the Samsung Note 4. Like the OP6, it has a proprietary "quick charge" mode, but I find it will also charge quite fast when provided with a non-Quick Charge source such as a battery that can source several amps of current.
How fast does the OP6 charge without the Dash charger and cable? (in terms of amps drawn from source?)
Like it would take years like why would you want to know this, if you broke your charger buy another and look after it like. It's one of the main features of the phone and they don't talk about how fast it charges like
At work i use a QC3.0 charger for my OP6. Didn't notice a great difference to the DASH charger at home. Maybe DASH is a few minutes faster.
40% to 70% charge with QC3.0 is still insanely fast.
Stay on topic guys. OP asked a question, which could be answered with facts, rather than opinions and scenarios. In my regular car charger, I go from 22 to about 70 in 40 minutes, if I can recall correctly.

I'm not sure if you're serious or sarcastic, but In case of the former, here are a few reasons why someone might be interested in charging with other than the Dash Charger:
1) AFAIK, Dash is available in AC mains or 12V Car charger versions. I often use a 20K mAH Anker powerbank battery for charging. That is usually in situations where other power is not available, but a quick charge is needed. Huge current is available, but would the OP6 use it?
2) I use a compact travel charger that has 5 USB charging ports. Using a Dash charger would require carrying another charger (big, bulky, without retractable prongs), and occupying one (or more due to the shape) additional AC outlets.
3) I have a phone charger in my bedroom, at my desk, in my travel bag (both AC and Car style), and in my car. A quick check on Amazon seems to indicate that the Oneplus6 charger is several times more expensive than other "quick charge" chargers. Over multiple charger locations, the extra costs add up.
Using the word "like" so many times makes it difficult to understand the post.

I'm Irish, apology
I have a stockpile of fast chargers that used the weird Nexus standard (5V, 3A, non QC) and they're okay, and for overnight or at my desk at work that's plenty fast to get the job done. The phone shows them as "charging" and not "charging slowly."
I purchased a "Tinduqin oneplus5T charger" from Amazon that works and looks exactly the same as the original dash charger for about $20, but it seems to already be sold out.
If you don't use dash charger,you only can charge at 5v 1.5a,I have tested it with apple 45w pd charger,xiaomi qc3.0 and nexus 5v3a charger

It won't charge very fast because it doesn't use any on board quick charge it's all in the dash charging brick
I have a bunch quick chargers 3.0 at home. It takes a life time. I end up buying the dash charger. I still use the quick charger for over night charging
there must be some sort of software restrictions on oneplus6 since measures show that oneplus6 cannot be charged with more than 5V-1.5A.

Do you own the OP6? Do you have a USB power meter that could measure the charging current with and without the Dash charger and reply with the values?
On my Note 4, it charges at about 1.17A / 5 V when the screen is on, and the current goes up to 1.6A with the screen off. That is with either a QC2 Quick Charger or a battery power pack. The phone reports "quick charger connected" in both cases.
oneplus6 has 85% battery left, measured with usb voltmeter and original oneplus dash charger 5V-4A, it shows that oneplus6 is dawning 5V-1.3A and same thing is happening with other usb chargers capable to deliver over 5V-2A.
I guess oneplus6 should be discharged less than 50% or something in order to start receiving over 5V-3A

Is it possible to use a the original DASH-adapter but with another USB-C cable? I need a longer cable so I can use the phone whilwe charging.
OnePlus has a original cable for sale which is only 150cm Long.
My question is if I can buy any other manufacturers cable whish also support some sort of fast charging. I've heard for example that DASH-charging is the same charging model that Huawei P20 Pro uses, they just have different name. .
So, is there anyone here that has switched the OP original cable and charge it up with a cable from another manufacturer?
There has to be a solution to this. Me myself can't. be the only one that needs s longer cable.

That's normal. Phones pull the most amps when on low battery, then progressively less as they are charged.
Check how much it pulls on <40% and <80% respectively.
Well, I charged my Op6 with a no-name USB 3.0 charger yesterday (forgot my dash charger at home, I was by a friend) and from 3% to 100% it took about ~1 hour and 55 minutes.
Not that bad I guess. But I still prefer my dash charger
I'm using a huawei p20 pro charger atm. Phone states from 75 - 100 it will take 33 minutes. (prob a bit faster if I don't use the phone.
Here is a charging session with a Oneplus 2 charger without quick charge
Charging from 27% to 100% in 2 hrs, 40 min - avg. Charging speed: about 1000 mA/h
Hello,
I'm using this old thread since we're talking about the same thing.
Is there a kernel or rom for the OP6 that enables to draw as much current as possible form third party chargers? It's sad that it's stuck at 1.5A no matter the charger unless you use dash charger. 2A is already something, 3A would be awesome.
Of course only if this a software limit.
