Find a fast charger, any recommended?
Stock from HTC direct (Digital River) works well.
I own the Aukey Quick Charger, which also works pretty well with the M9:

I use the samsung fast charger from the note 4 or s6 and use the motorola brick from the nexus 6. I recommend the nexus 6 brick.
I will receive my techmatte quick car charger and keedox quick wall charger tonight, will let you know

That's the same one I use in my office. Works well.
I use the charger from my old Droid Turbo at home.

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

Thought I'd give my thoughts on the Qualcomm Quick Charger 2.0.
Just received the HTC One M9 yesterday.
After a full charge with the stock charger, I had it running for 13 hours without charging.
Woke up this morning and noticed that it had dropped to 34% so I decided to try the Qualcomm Quick Charger 2.0.
Wow! Impressed how fast it went to 100%! Actually I had my doubts about it going 60% in 30 minutes, but it does seem legit.
In my opinion, it is worth well purchasing, specially if you suddenly find yourself with no power left and in need of charging it fast!

I got the CHOE brand Quick charge and it is indeed very impressive. What Ticks me off is that's the charger that should have been in the box with the M9. That's poor of HTC to flaunt a much better charger on their website after shipping out the normal ones to their loyal customers.

I don't have the M9, but from unboxing videos it looks like HTC included the Quick Charge 1.0 charger with the phone. Looks very similar to the one that came with the M8. But I agree, with the M9, HTC had NO excuse not to include a Quick Charge 2.0 charger.
I was wondering if you guys knows if the actual charger of my Nexus 6, could be compatible with the HTC One M9 ?
As it's not included in the M9's Box... If i can keep my actual one, that'll be great !
I've bought this charger too, very happy with it! Charged +88% in 68 minutes

How long it takes to charge from 0~100 ? less than 2 hours ?
My phone said 5 more minutes till full charge when I unplugged it and made the screenshot in the previous post, so I guess full charge from 0 to 100% will take less then one and a half hour. I'll give it a try soon.

Just so everyone knows, fast charging a Lithium batter would work best going from 0 to 70-80% any more than that the battery charges really slow, that's just how chargers are designed for lithium tech.
Example, from 0% if the charger is giving out 2Amps, then as soon as it reaches a high point of 80% the power output goes down from 2Amps to around 1Amp, and so on it keeps declining as the battery get higher.
Does this work with any good quality micro USB cable?
Quick Charge with Verizon phone?
Has anyone with a VZW M9 had any great success with a quick charger? And if so, what have you used?
I have the Tenergy Fast Charger, and it is faster than the charger that came with the phone, but it's definitely not super fast. We're talking just slightly over 1% per minute.
This makes me wonder if Verizon has somehow limited quick charging with this phone such that any charger I try is going to be met with limited success or if I should indeed try a different charger.
Is anyone else having trouble getting the fast speed? I have a T-Mobile variant and it seems to be only getting about 1% per minute as well. At 60% charge, it estimates that there is about 50-60 minutes remaining to completion.

Same here, with both Samsung adaptive fast charger and Motorola quick charger from a nexus 6. No idea why, but after using an s6 that charged extremely quickly, it's a little confusing.
I wonder if some of the carrier variants that received the update had the QuickCharge 2.0 functionality disabled. I've tried the Aukey, Anker, Getwow and Onite chargers and they all are not charging at the rated spec.
Quick charge is neat, but it's also destructive for the battery. 95% of the time my phone is only on charge over night, so no need for speed there. I'd rather it have the regular charger for the overnight charge, and maybe having a quick charger for on the go situations.
I just bought iVoler quick charger to try it because the price was low and the reviews said it was quality made. I Just received this the other day, and I plugged in my Z4 Tablet and it said Z4 Tablet detected, so it indeed does support the Qualcomm Quick Charging feature! Charging was fast and held strong with my Z4 Tablet. Charging the battery from 0 to 25% in about 19 minutes. And the 6 foot USB cable is of good quality and really nice. It also fits into my Z4 Tablet with a nice click, and fits well around my case. I will definitely buy more of these!
The great product need to be shared.
http://www.amazon.com/dp/B00WSLRCWI
is safe to use ? I'm just wonder why Sony has not advertised this feature
Well, the Z4 is listed as supporting quick charge on Qualcomm's website: https://www.qualcomm.com/products/snapdragon/tablets/sony-xperia-z4-tablet.
I have tried 2 quick charge chargers from amazon so far with the z4 tablet.
No problems and it works with most recent xperias and other snapdragons.

What kind of charging times are you seeing with the quick charge 2.0 with a battery that big? i.e. 80% in x mins from empty etc. I have been searching for an answer to this but it doesn't really seem to be posted in times but percents.
Thanks

You are welcome. It is a great charger. I use it with my LG G4 as well.
So, the Sony charger that comes with the Z4T isn't a Qualcomm Quick Chare 2.0 charger, right? A quick check says 1,5A / 5V and that's also what I measured with a USB gadget. I got the same results with my QC 2.0 charger from Samsung...
I'll try it again with another QC 2.0 charger.
/edit: yeah, the shipped charger isn't QC 2.0. Not sure why my Samsung charger didn't work out though, but I'll test my Pisen QC 2.0 charger tomorrow
HI guys I just test it with my Galaxy S7 / Note 5 quick charger with the tablet USB cable and I'm getting full charge in 1hour 15 min.

This one is good : [Qualcomm Certified] Tronsmart® Quick Charge 2.0 18W USB Car Charger
Opt among 1 output, 2 output or 3 output. However, please note that only 1 output port supports Qualcomm Quick Charge 2.0. Rest 2 are fast, however, not QC 2.0 Fast.:good:

Check slickdeals. I've been using the $5 one (on sale). It outputs 12v so it charges the phone very fast.

This is 2.1amp, and is the smallest, it can virtually snap right into your car charger port, without the protruding charger popping out.

Technology is same. High Volt, low Ampere. Any QualComm Certified QUick Charger would be compatible with Samsung's Adaptive Fast Charging. Atleast any branded ones, never go for any unheard brands. Usually Tronsmart, Aukey and Anker are good choices in average budget. Here's a video review I did for Tronsmart Adapter (Quick Charge) with my Edge+ :- https://www.youtube.com/watch?v=DR8W9ozZgAs
Also, please note that I have no affiliation with any of these brands, I just received a product for the review from Tronsmart and I found it really good. And I'm sure Aukey and Anker are equally good.:fingers-crossed:
Also, the Car Charger you are considering isn't fast charging compatible. Although it will not take much time with high Amp output (as specified), but its definitely not a fast charger.
Well, I am using CHOETECH’s Dual USB Car Charger with a dedicated port certified by QUALCOMM’s quick charge 2.0 technology so that I can charge my S6 Edge plus at quick charging rate even on the go. The main specialty of this charger is that it is not only charge the fast charging devices but also Apple devices like iPad Air 2 or iPhone 6 plus at much fast rate as compared to their original charger.

Thats very good info. Charging technology is evolving with the phones, and thats a very positive start.
The day is not very far when we might have multi thousand mah of battery juice and charging becomes a weekend job.
Do you mind taking notes while charghing 20% of battery with both the qualcomm fast charge, and the regular 2.1amp charger.
I've already placed an order for the Aukey 4.8A / 24W Dual USB Car Charger mainly because of the size. I'd really want a charger that can **** plush within the car's charging port.

Charging isn't a very quantitative process. First 20% of charging would never be same as next 20% of charging. Usually with fast charger, the first 20% would be amazingly fast while the regular 2.1 amp might take upto 1.5 - 2 times the time. Also, assuming two different devices have same sized battery, with the same charger, one might get 70% charged within 30 min while the other can get 80% charged. However, by the end of 100%, both might take similar time. Thats why, the % readings aren't very consistent or dependable. Its approximation. With 2.1 Amp charger, you won't loose much time, trust me. Also, I don't have the facts, but I have noticed that when I do the fast charging, battery drains out marginally quicker than when I charge through regular 2 Amp charger. Hope that helps.. :fingers-crossed:

Thanks that was good info. I've received my 2.1Amp Aukey charger.
I tried it yst evening while commuting back home from work, which is about 20min drive, and the phone was at at 50%, and it was able to charge about 30% in less than 30 mins. Looks promising. I love the form factor. you cannot evne see the charger plugged into the car port. Best of all, the car port's cover covers the entire charger when not charging, this way i dont even have to remove the charger jack every time i have to charge the car, just pluck out the wires, and snap the cover back to conseal the charger.

With constant gaming and videos watching (after working hours ofcs ), mine doesn't stay beyond a day. I'm very happy with that though. I have seen significant different in battery life when I keep the power saving mode on and it doesn't really impacts my gaming at all even though it says that power saving switches to the 1.5 ghz cores and stays that way...!
It doesn’t matter a lot but yeah the main thing is internal circuit and the premium component used in the manufacturing. All of the chargers integrated with Qualcomm Quick Charge 2.0 chip inside. But the best components used in the manufacturing plays a vital role. I can trust CHOETECH more in this area as they are offering 18 months warranty, which means they are confident about what they produce or deliver to their consumers.
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

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 !

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

I have 4 chargers on hand listed below...
1. Original Samsung Adaptive USB Charger
2. Anker PowerCore+ 10050+ QC 2.0 Charger
3. Anker PowerCore 10000
4. Pleson Fast Wireless Charger
Now my question is why is my S8+ charging similarly with all these chargers? Example @ 30%.... The Adaptive charger says 1 hr 9 min (reads fast charge), the Anker 10050+ says 1 hr 25 min (doesn't read fast charge), The Anker PowerCore 10000 says 1 hr 25 min (Not a fast charger), and the Pleson Fast Wireless Charger says 1 hr 44 min. I am confused.

Because only 1st one is actually fast charging your phone.
You should try 2 and 4 with original cable. If you have qualcomm version of s8 shold work
I'd echo the original cable and the wall plug that came with the device. Retry all 4 of these with the original cable and the wall plug.
Well I don't know if the Anker products are charging oddly because one is QC 2.0 and the other isn't, yet both have same 59 min charge time. So I question is the Samsung Adaptive charger is charging slow or fast? Here are some pics of the remaining charge with original black USB Cable.
From my experience, Samsung Devices don't really play nice with qc certified devices thanks to Sammy doing their own thing. What you are seeing is what made me buy Samsung's power kit.

I have no issues with my chargers, use stock charger blk, use sammy wireless charge pad with aftermarket cable and s7e wall plug charger and no issues. Still get fast charge. I even have a portable 10000mah sammy pack and use my gopro usb-c cable n gef fast charge.
Do you mean this one....

Had similar problem. All my Anker QC2.0 doesn't fast charge my S8 while 3.0 does. got them both refunded while they are investigating.

Strange
does that mean S8 has QC 3.0
Yes I am in talks with Anker as well, seeing what they find out about my QC 2.0 Anker charger.

They sent me another QC 2.0 car charger, and it did not fast charge. I am going to try Berkin USB-PD car charger and see how it goes.
Estimated time. Don't expect them to always show exactly the time.
I have QC 2.0 and 3.0 chargers and they all "fast charge" but I don't expect what the estimated time show to fully charge be accurate or else they wouldn't say estimate.

Yes except bestbuy carries that with a dual Samsung fast charger for car and a nice wireless upright fast charger all in one box for about $99 on sale every other week. Way more consistent everywhere now.

Compared to my s7edge this s8+ charges a lot slower. The s7e would fast charge and wirelessly fast charge from any third party wireless pads/adapters.
The s8+ is finicky about what activates fast charge (especially wireless) and even while in fast charge it does not charge as fast as s7.
My guess is samsung slowed the charging down to help with battery degradation.
I found a weird thing last night when I set my phone to charge at 2 AM with about 7% battery just to wake up around 6 AM and it being at 86% charged. That was a long time, I don't know what's going on. Either the phone isn't quick wireless charging or the Pleson Fast Wireless pad I have sucks.

So, I've seen this behavior too. If you see the charge stuck, unplug the cable and plug it back in. I'm not sure why, but that fixes the issue immediately.
Are you guys charging in a warm room? S8 will stop charging if the battery exceeds a certain temperature. Samsung really went overboard with battery safety after the Note 7.
