Quick charge 2.0 indication.

Is there a way to tell whether you're charging with a Quick Charge 2.0 compatible adapter, vs a standard 2.0A fast charger? Maybe I'm missing something, but the Nexus 6 shows "Charging (AC)" either way.
I know that QC 2.0 requires that the data pins of the cable be intact, and if you plug in a charge-only cable it falls back to QC 1.0 (standard 5V, 2A charger). I'm looking to buy a couple QC 2.0 adapters, and it would be nice to be able to quickly tell if I got my money's worth WITHOUT having to drain my phone and time how long it takes to charge.

I noticed this too. My wife's Note 4 shows a message indicating that its charging via fast charger (aka quickcharge 2.0).
For our phone, I would suggest just plugging it into a known working quickcharge 2.0 charger, like the one that came with the phone. Wait 1 min until it shows the time until full. Then switch to your new charger, wait a min, and compare the time remaining until full. If they are close to the same, then your good to go. At least this would save you having to fully discharge and time the recharge...

The easy way is to use the charger that came with the phone

No indication.
but it is faster, I ran my 2.1a charger against it.

You'd think that, but accidentally plug the wrong cable into that charger, and you'll THINK it's quick-charging, but if that cable happens to be a charge-only cable, it will be locked to the 5V setting, which with the Moto charger, is at 1.6A. Besides, for some reason, the charger that came with my phone worn't fit in the little round charging hole in my car, so I'm looking to buy a QC 2.0 car charger. The point of my OP was that anyone can slap the words "Quick Charge" on their Amazon product page (especially since any 2A charger is technically a "Quick Charge 1.0" cable -- even if the ad says 2.0, well, that's just a typo -- should have said 1.0... oops!), and I'm looking for a way to quickly test the product I receive.
@TheSopranos16, Good suggestion about waiting for the "...until fully charged" message pops up. I'll have to test that to see if it really does show a different time that quickly with a QC 2.0 adapter. Still, it's something that the Note 4 can see, so I'm thinking it's something that an App should be able to see. I briefly looked, but didn't find one. I was kind of hoping someone else had.

Well i used my N5 cable that came with the charger and didn't even notice the difference, changed back to the moto one because i don't like the glossy look on the LG one.
By any chance you tried using your cable in your car?? Did it charged?? I tried to use mine in my car and didn't work, I got a 2014 corolla maybe it's because of the small battery in the car, I really dunno. It's weird.

Yes I too would like to know what charges and cords work correctly...

UPDATE: Okay, this worked... sort of. Well, it definitely worked, but it wasn't quite so simple. My phone was at about 71% charge, and I put it on the Moto Turbo Charger. A minute later, it said it had about 25 minutes remaining for a full charge. I removed it, and placed it on my Nexus 7 charger (which, incidentally, is only a 1.2A charger, but it proved the point). It took over 5 minutes to show the "charge complete in..." message, in which it indicated it would take over two hours. I guess, you could consider the extended wait time a sign, but something NOT happening is always a really bad way to prove something. Still, once it DID show, 25m vs 2h is definitely a good measure.
The weird thing is... it took about 5 minutes to show that message on the 1.2A charger, during which, the charge increased from 71% to 74%. Assuming a similar 3% increase every 5 minutes, it should reach its full charge in about 45 minutes, not the two hours it stated. Since this was only a 1.2A charger, a 2A charger could do it in almost half that time, or about the 25 minutes that was initially reported. Still, I was at 71%, and at that level, the Turbo Charger may not shift into 9V or 12V modes, so I guess that seemed about right.
I'd still like to see an app that could tell me instantly or, at least, within a few seconds, but this is definitely an alternative. Although, you still really need to test it while the battery is pretty low, but at least it stops the necessity to time a full charge.

You could monitor the charger output with a USB voltage and current meter. For regular charging the adapter output will stay at ~5 V. For Quick Charge 2.0 the adapter output voltage level will go to ~9 V. Just make sure that the USB power meter supports at least up to 9 V (better 13 V) and 2 A. It also needs to have the data lines. Here's one that would work (supports up to 10 V and up to 3 A): http://goo.gl/3OoD3D

Op, just look at the charger specs, by law the wallwart should have a power rating blurb printed on it. Quick charge 2.0 will have variable voltage as well as amperage. 1.0 will only crank the amperage, but not the voltage

Alas, car chargers... not so much.

i use and watch the current widget. the nexus 6 default charger has nearly 2450mV coming in at a certain point of its charging cycle! no other charger will do that for you, i dont think.

op brings up a very good point that i didnt realize before. on my note 4, when you plug in the nexus 6 moto turbo charger or any other quick charge 2.0 charger a window pops up explaining adaptive fast charging. you can dismiss it and make it never show up again. you also get an "adaptive fast charger connected" notification in the notification bar. these are very good things. on nexus 6? nothing...

Are there any quick charge 2.0 car chargers? I'd thing you simply hit the power ceiling of the cigarette lighter before getting close.

Actually, most vehicle power outlets have a 10A or 20A fuse (cigarette lighters tend to be on the lower end, while power outlets tend to be on the upper end), and operate at 12V. Even at the lower 10A range, that's 120W of power. Traditional USB Car adapters step that down to 5V at up to 2A, or about 10W of power. The QC. 2.0 standard allows for 3A at 5V, 9V, or 12V, for a maximum of 15W, 27W, or 36W respectively. That's well below what your car can handle. Not to mention that none of the existing adapters even come close to that amperage. Most that I've seen only run at 5V or 9V, at 1.67A. That only 15W at 9V.
So... to answer your question. Yes, QC 2.0 vehicle adapters exist (check out Amazon), and no, they won't even come close to hitting the power ceiling of your car's cigarette lighter / power outlet.

Ooh! I like that Verizon car adapter. That LED at the connector would really come in handy! Thanks, @indianajonze!

You can also use an AC meter such as Kill a Watt
http://www.p3international.com/products/p4400.html
Which might be more useful to have around the house. You should see the charger drawing about 5W for standard 1A USB charger, 10W for 2A and up to 14-15W for turbo. The battery widgets others have mentioned work great too.

[Q] Quick Charge 2.0

So yesterday I bought a 2.0 charger off of amazon with the choe brand name. According to the ad it works with nearly every android phone, including the HTC one m8. For the past year I have been using a charger from my last phone which was a crappy flip phone and thought nothing of it, but I am wondering does this charger truly work?? According to app "Ampere" it is much slower. Also, I've read reports about phones heating up and that's what mine did last night, is that normal? How long should it take for me to full charge my HTC one m8?

It will heat up, that is normal. It'll use most of its 2.4A between 20 and 70% and then slow down. Your total charge time shouldn't take more than 1 hour, and make sure you're using the supplied cable.

Thanks for the response! So if it doesn't charge 1 to 100 in 1 hour than is something wrong? Also will a charger like this have any effect on how long my battery lasts? My last charger for whatever reason was for my last flip phone believe it or not, I never bought a new one.

no I wouldn't say that.
my 2.0 QC will get it done in about 1-2 hours compared to the 3-5 or so it took with stock charger.

0-100% will take more than an hour. I've timed mine a few times from 0-100%, not using the phone at all and in airplane mode waking it up every 5 minutes to check percentage, volts, and charge rate using Gsam batt monitor.
Comparing the two chargers (OEM HTC QC 2.0, and original HTC charger- which I believe is QC 1.0) the QC 2.0 is definitely faster. Even though there is nothing on the phone telling you it is using the higher wattage charging mode, it is. So, 0 to 100% using HTC's QC2, usually takes around 1:20 minutes if I remember right. As in the other post, it starts out rather slow to around 20%, then kicks in to high gear until around 80%, then slows back down all the way to 100% so as to not overcharge the battery and harm it. It really is amazing the speed that it charges at. It does get rather warm, which is normal, but shouldn't hurt the phone.
Now, completely draining and recharging these batteries frequently is not good for them and will decrease the useful life sooner. Keeping it somewhere around 80 % is ideal but realistically not practical and the manufacturers know that. That's why they build in overcharge circuitry protection so leaving the charger on all the time "shouldn't" harm the battery. Draining it down to zero and doing a full recharge cycle on it frequently WILL decrease the lifespan. The batterie's useful life is basically determined by a finite number of charge cycles.
There's tons of info on charging and batteries out there if you are looking for more reading too.

Anyone heard of the brand Auzen? It's popping up alot on aliexpress and around asian market. Not too much reviews yet on that brand.

don't play with quick chargers .I bloated my m8 batt once trying it .it charge at 2.4a .our device max is 1.5a.
If you insist using it then don't full charge with it n monitor closely .

That's impressive, I use a QC2.0 car charger, I use a variety of wall chargers that run from 1.0A to 2.3A at 5V.
So far, my battery is still very happy.
Sounds like you got a cheap knock off charger or your battery/charging circuitry was damaged/faulty and/or your ROM/firmware weren't proper, for that kind of damage to occur.

I don't think Ampere works. I once did a test (last month) and had 6 different USB cables and I wanted to see which was the best, every time I used one I got a different reading, from 200 up to 1600. Even using my Anker Quick Charge 2.0 I only got 400 so it stated.

I have been using Aukey QuickCharge 2.0 and gives pretty decent charge times.

I have a QUICK Changer 2.0. works great.. have some tips...
You know there is some colors on cable conectors ends you have to choose the right one..
- If the cable is not a quality one can result to slow charging.
Black ----- 1.0. most in stock phones
White------ 2.0. the right for fast charging...
The time on reaching 100% on battery,well Quickly charger 2.0 will reach 80% on your battery fast and it will change the next 20% slower...
There is some app in playstore can help can see the amperage live in mA..
Connect your charger to get the battery charging current or disconnect it and get the negative discharging current... and you can see your battery charging current mA is constantly changing because even on charging phone still using current (negative discharging current) and this is always changing.
On my case I see higher mA reading only under really low battery...

I have a problem with my m8 and aukey 2.0 quick charger....
After firmware update to 6.12.xxx.xxx mm , the app ampere tell me max 1600ma before update its tell 2000ma .. Its a bug or a feature of the new firmware base...??? I have cyanogenmod 13

Im using the same aukey 2.0 quick charger. Works perfect.

M8 is 1.5a max .if you use 2.0a logically you're overcharging it. Just wait for it to get bloat n replace the whole bat. worth it ?

Hi, i just wanted to say something. After many bad chargers i bought, i found the Nillkin chargers (2Amps)and Nillkin cables (2.1Amp) the best and best quality. I am always testing with good Usb voltage tester and it can charge up to 1.5 amps max on M8 and on LG G3 1.8 Amps. As long as the charger is 5.0V, amps can variate and it doesnt hurt your battery, it just charges slower or faster. In my case its charging 1% per minute on both phones. It doesn't matter if the cable is black, white, green... cables must be thick, around 18AWG that support high ampers which mean faster charging. thin cables are sh!#. And for car i also found the Scosche dual charger great for every device with Nillkin 30cm cables and Kenu airframe holder.
You can use 2.4A chargers on M8 without problem as it will only receive 1.5amps.

I'm using Anker PowerPort 1+. It's very good and you can use for iPhone iPad & almost Android devices.

That logic is incorrect. The phone will only draw as many amps as its rated for (1.5 amps) regardless of what the charger is rated to supply. Think of the charger amp rating as the "maximum it can supply" instead of "what it will always supply".

review of the CHOETECH 15600mAh Dual USB Quick Charge 2.0 Power Bank

Our review of the CHOETECH 15600mAh Dual USB Quick Charge 2.0 Power Bank!
Mod edit: Thread closed and content removed.

This is a absolutely great charger. It is very much portable with a sleek, beautiful looking design and the performance is excellent. It has the fast charging feature that charges my S6 edge extremely fast. I take this power bank with me on road trips and it performs at a great rate for my s6, my wife s6 and my lg tablet all at the same time. I will never leave home without it. The battery life on it is great after you charge it fully so it can be used for long periods of time especially since it has that huge amount of battery power. Choetech keep up the spectacular work!!!!!!!

How well does it charge from the secondary USB port? For an example an iPhone? I hope it isn't terribly slow.

It won't charge the iPhone too slow, because both inputs charge at a max rate of 2.1A. Output 1 (standard) provides 1A, and output 2 (QC 2.0) at 2.4A. What's unique about the CHOETECH power bank is its ability to be charged using either a microUSB cable or Apple Lightning cable. Hope this information is helpful for you.

I'm specifically asking how quickly it charges out of the 1A output. Most phones these days accept 2.1A for charging and I'm curious if this 1A output will be useless to me. For example, if I am charging a Galaxy S6 from the QC 2.0 port, and an iPhone 6 from the 1A output at the same time, how would the charge rate of that iPhone compare to an iPhone plugged into a wall charger that puts out 2.1A?

The charging rate would be slow if you charge your iPhone 6 from the 1A output, as the iPhone 6 typically charges out of a 1.5A output. The power bank has only one quick charge port, which is compatible for both Android and iOS devices.
A battery capacity of 2915mAh like for iPhone 6 will be charged in 1A for approximately 3 hours 48 minutes. The difference in time will be determine in the Ampere of the charger. There are advantages in doing a slow charge so the 1A output will not be useless at all.

For the price and features this seems like a no-brainer to me. Just ordered one.
I'll report back once I receive and use it.

I've had issues with Aukey chargers not properly charging my G4. Seems as if some people do, and some people don't. I can say that I've never had an issue with Anker QC2.0 chargers. I'm using the Anker Power Port+ 6 port charger. It has QC3.0. Getting great results with that one.

Samsung adaptive fast charge AC adapter works with G4.

I use Anker Charger with a 2.0A Cable works well

Using Aukey Quick Charger with the aukey cable and the quick charge was a fine think!

I thought I'd look in this thread for a charger but I see none talking with proofs. When we talk about chargers we should post a screenshot of our mA while the phone is charging. This lovely app "Ampere" would help a lot. Without a screenshot anyone can say anything and everyone sais very fast. But How many mA is this very fast?

I use the v10 and g5 quick charge lg plug and samsung quick charger both work well

2A at 120V would be dangerous over such a small wire and, at 240W, enough to really heat up a phone. But 2 Amps at 5 Volts (USB standard) is only 10 Watts, which going into the phone is no problem, and not enough to substantially heat up the wires
With Quick Charge 3.0 at 12V, you're getting up to 24W going into the phone, which may heat up your phone pretty well, but it's not going to self-destruct as long as your battery actually charges.
Thinking about the math for 20 AWG wire:
Resistance/length: ~10 Ohms resistance/1000 ft. per this chart: http://www2.seas.gwu.edu/~ecelabs/appnotes/PDF/techdat/swc.pdf
Resistance=.01 Ohm/ft * 3ft = 0.03 Ohms in the wire (you'll have more at the connectors due to contact resistance)
Voltage drop in the wire = I * R = 2Amps * 0.03 Ohms = 0.06 Volts by Ohm's Law
Power dissipated in the wire = V * I = 0.06V * 2 = 0.12 Watts
The power into the phone is (at 5V) about 100x this, but as long as it's effectively being converted into chemical energy in the battery, you've got no worries!
One thing I'd look for on any charger now is a Level VI label. This certifies that it meets efficiency requirements as set by the US Department of Energy. From most of what I've seen, if the designers are bothering to make it that efficient, they'll make it safe too, and the efficiency somewhat inherently guarantees the charger won't get hot enough to be dangerous. The latest Anker QC3.0 charger I got is Level VI efficient, and I would suspect Aukey's recent chargers to be too.

Qi Wireless charging problem

Hello!
i've bought Nillkin Disk Charger III which support fast charge (9V/1.7A max 10W) so does original Sony XZ2 charger and XZ2 itself. Sadly, when charging using Nillkin, XZ2 uses normal charging mode, not fast. 25% in hour. Only 400-500mA on wireless charger vs 2600mA on cable. With or without phone case, doesn't matter.
What can I do to charge it faster?

Bump.

Buy offical one by Sony

I use this one and all is fine. https://www.amazon.com/dp/B01KJL4XNY/?tag=flv-21&ascsubtag=6987aeb4-b272-4b5f-935b-f94acfec1a3d

Can you download Ampere app from the play store and run it while charging on this Anker pad. Let us know if this one can really charge the XZ2 beyond the standard 5w speed. Report the mah if it can exceed the 800mah standard qi rate. Remember, fast wireless charging at 9-10w should be around 1400 to 1500mah.
I have tried 7 different brands of fast 10w wireless chargers so far (but not an Anker yet). None of them can exceed 800mah on the XZ2. I wonder if the official Sony one can really do it at 1500mah.
So, please use Ampere and report back your results with the Anker, thank you!

Report the mah if it can exceed the 800mah standard qi rate. Remember, fast wireless charging at 9-10w should be around 1400 to 1500mah.
I have tried 7 different brands of fast 10w wireless chargers so far (but not an Anker yet). None of them can exceed 800mah on the XZ2. I wonder if the official Sony one can really do it at 1500mah.

I think this video can give you an idea of the Sony wch20 charging profile: https://youtu.be/BnasDqGFcFg close to 1500mah but not for a long time.

I too have a similar question. But it's about maximum allowed power for XZ2 wireless charging.
I just talked with Sony support and they too have no clue how XZ2 Qi wireless work. They told me better to buy (if at all) other brands' chargers with output NOT exceeding 9W, since it is the maximum output by the official Sony wireless charger.
But apparently some 3rd party brand reps told me that Sony uses Qi 3.0 and 10W chargers are completely fine. And all fast charger on Amazon output 10W with Qi 3.0 adapter.
So I am really confused whether those faster charger is safe for XZ2 at all.
'And it is very confusing that the Sony original adaptor has 3 working power: 5 V 2.7A DC, 9V 1.8 A DC, 12 V 1.35 A DC.
What do you guys think?

That's called Qualcomm Quick Charge.
While USB is specified for 5V QuickCharge 2.0 can use 5V, 9V and 12V (not used in phones).
QC 3.0 is even better as it has adaptive Voltage scaling from 4V to 9V theoretically.
Practically it's around 4.6 to 7.5V changing fluently during the charger process.
For normal cable powered charging the device itself decides how much amperage it wants to draw. The wall charger can only set an upper limit like 'only has 1.5A at 5V'
As wireless charging sends out power I think there is a communication between sender and receiver which handles the power output. Haven't really read much about that though.

Hi,
Has anyone found a charger other than the official one that will charge at more than 5W? I bought a 10W wireless charger from Amazon and it only charges at 5V 1A whereas the same charger charges a friends iPhone at 7.55V 1A. Has Sony built something into the phone/software that only enables 9W charging with the official dock?
Thanks

Not so far. Got a Seneo fast wireless charger and some other brand I can't remember the name of; both tried with multiple QC charging packs I have lying around (and even Sony's brick supplied with the phone). According to AccuBattery, the XZ2 never pulls more than around 700 mAh, while my Lumia 950 XL hovers around 1700.
I'm thinking you're right, there is something special the XZ2 looks for in their WCH20 wireless charger unfortunately. I've tried turning Battery Care on and off too but that hasn't changed anything as far as raising the current draw.
I really have to try it when the battery is below 20% though to be a fair test.

Update: So I bought an Anker Powerwave wireless charger and QC3.0 adapter which Anker claim supports 10W charging on the XZ2. I have tested it and it charges at 7.45V at 1.2 Amps so not quite 10W but it charges from 0 to 100% in 2 hours 50 minutes which is much better than the first wireless charger i bought which took over 4 hours 30 minutes at 5W. Hope this helps.

actually, 7.45v at 1.2A is 9 watts. Which is reportedly the XZ2's peak draw.
A couple questions:
What did you use to check the charging stats? (I'm using AccuBattery currently). I don't think the latest Xperia phones have any fast charge indications like some other OEM's do.
Was the 7.45V/1.2 amps reading at 0% battery?
Was Battery Care enabled?
Did you happen to check the charge levels at various times during the 2h 50m and see if it fluctuated?
I'm using an Anker QC 3.0 charger with my Seneo which charges great over USB, so I don't think my problem is the charger. I'm going to let mine go to below 20% and try again.

I use accurate battery on every device I maintain.
At least to give an alert, if 80% battery capacity is reached during charging.

Sorry, yes I know its almost 9W. I was just making the point that it didn't reach the 10W Anker claim it can.
I use an inline USB amp meter...
The 7.45V 1.2 amps was from 0% to 70% after that it was 7.45v 1.0 amp until 100%
The 1.2 amps could only be achieved by careful positioning on the pad, if it was slightly to the left/right it would drop to 1.0 amp.
Battery care was disabled.
Thanks

I think the 9W cap is Sony, not the Anker.
I'm going to send back my Seneo, obviously something is not working right with the XZ2 regards fast charging. Tried it with several different QC chargers, moving it around on the pad etc..
Thanks!

No problem
I would love to test out the WCH20 but in the UK Sony want £129. Have found it on Amazon for £70 but it's still silly money for a charging dock!
If you're considering the Anker Powerwave, it is very good. My only gripe is even though it stops charging once the phone reaches 100%, the cooling fan keeps running until you remove the phone from the pad which seems like an oversight.
Cheers.

Hello!
i've bought Nillkin Disk Charger III which support fast charge (9V/1.7A max 10W) so does original Sony XZ2 charger and XZ2 itself. Sadly, when charging using Nillkin, XZ2 uses normal charging mode, not fast. 25% in hour. Only 400-500mA on wireless charger vs 2600mA on cable. With or without phone case, doesn't matter.
What can I do to charge it faster?

I have the Nilkin charging stand for my XZ2 Premium and I am more than happy, it takes about 2hrs to go from 50% to full charge, it will never be as fast as wired charging, and the battery life on the Premium is great, I can easily get 2 days but would rarely need that.

Sony WCH20 can do 1700 mAh but only to 50% of battery charge. After that it is slower 1400 mAh and that again slower.

Guess I'll have to try the Anker Powerwave (which one did you get if I may ask?). I tried yet another brand, which again, fast charges my old Lumia 950 XL just fine around 1600 mAh, but the XZ2 refuses to go beyond ~700 mAh. Wondering if it's my phone or the XZ2's coil is just in a weird spot.
I'll have to spring for an inline USB meter. maybe it'll help me find the "sweet spot."
