QuickCharge 2.0 tests

I bought a few QC2.0 chargers for my AT&T G4:
2-pack Samsung Adaptive Fast Charge AC chargers: .walmart.com/ip/45734981
Tronsmart Dual Car charger: .ebay.com/itm/191645992162
Aliexpress knock-off single QC2.0 car charger: .aliexpress.com/item/Qualcomm-Quick-Charge-2-0-Stand-USB-QC2-0-Car-Charger-for-Samsung-Galaxy-S6-HTC/32364542508.html
..... and compared with the performance of the STOCK LG G4 1.8 Amp (non-QC2.0) charger.
[Note: front end of URLs ( h tt p : w w w.....) left off since newbies like me can not post external links]
I charged my G4 with power OFF, and used Battery Monitor Widget
( play.google.com/store/apps/details?id=ccc71.bmw )
to measure before and after % remaining,
I "generally" began the charge cycle when the %remaining was low (3-16%, 11% average)
and charged for about an hour (52 minute average)
For each I repeated the test 2-3 times.
Here are the results:
Stock Charger: 1.033 avg, 1.04 max % per minute
Samsung: 1.249 avg, 1.300 max % per minute
Tronsmart: 1.248 avg, 1.290 max % per minute
AliExpress: 1.221 avg, 1.270 max % per minute
So.... even though QC2.0 CLAIMS to charge up to 75% faster, my results were closer to 25% faster
All the QC2.0 chargers were rather consistent in their performance.
I found ambient temperature was an important factor.
The 1st test with the AliExpress was done in a closed car on a 110F day (without AC on)
I got 0.25%/min - but disqualified this result due to the temp extreme
(All other car charger tests were done with car running while driving with AC on)
I'd be interested in seeing if anyone else can test their chargers similarly and post the results here.

I thought QC chargers only quick charged QC compatible devices?
G4

And G4 is QC2.0 compatible, isn't it?

They do. The Qualcomm website claims that G4 is QC 2.0.

I would think testing closer to 70° would be wiser.

I get this spike using my 2.0 charger, it never stays that high for longer than 10seconds.

Que QC 2.0 on the G4 is a joke, it barely doesn't even exist.

I can't even use my quickcharge 2.0 charger. Anyone know why that may be the case? I'm on software version G, the charger works perfectly fine with my note 4 for quick charge but not on the G4... It's a GETWOW qualcomm quick charge 2.0 charger

Your battery is 90% full, is it any different if your battery is lower, like 10%?

My Keedox qc 2.0 is charging my g4 faster than my ex-m9! It can fully charge from 45 to 100% in 30 mins only, it was 50 mins with the m9!!!

No complaints from my Quick Charger

Ive got the uk plug aukey single port quick charge 2.0. Did a timed charge last night 14->48% 25minutes (1.36%/minute), 48->71% 16 minutes (1.44%/minute), 71->92% 19minutes (1.11%/minute) - total time from 14% to 92% one hour (1.3%/min) so about the same as OP test.

With custom kernel we should be able to reach much higher charging rates...on g2 with dorimanx kernel i never saw anything below 1600 and got up to 21xx

Agree. I use aukey QC 2.0 3 port. Using QC 2.0 port, or just the same charging time using stock charger. From 5%-100%, both need time about 105 minute. No different. I sold my aukey.
Aukey using 9v (8.9v exactly) and 5v for stock charging.

OEM or any good charger

The oem charger has broke, need a new one
Model mcs-04er
At ebay and aliexpress they described it as "original/genuine/oem"
Not really trust them...where can I find a original charger (good price) of other recommended one?

The newest SAMSUNG 2A charger :TA20EWE (Best one from s6/s7)
The newest Samsung USB cable (normal, not any Type C) : DG925
I'm using this two for 3 weeks and its faster (1h and 20 mins 0-100%) than stock lg charger. Unfortunately I dont know where to buy it in your Country, but this might help anyway

aukey
I use an aukey like this one:
http://www.ebay.com/itm/Aukey-Quick...9b4ac89abf8d425a5b945c&pid=100507&rk=1&rkt=1&
it uses quick charge 2.0 and is very fast and reliable
they also have the same chargers for your car or portable power banks for off the grid use
highly rated products, you can't go wrong with these.
you can search ebay for more

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 use a voxlink QC 3.0 with amazon basics cable.

Im using a QMadix Quick Charge 2.0 and it charges very fast!

Yeah lol

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.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG Q6 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Well charger supplied in the box is 1A so dont think thats quick charge isnt 2A quick charge not sure without looking into cpu specs the SD 435 supports it but its charges quicker than standard say , allso hooked up to my pny power bank that does 2.4A and charges fast battery life seems good

So you are saying it charges faster with other fast chargers??If yes,how much time it takes?

Well, after a little test. The phone has charged from 2% to 100% in 1 hour 17 minutes approximately.
It is a 30W Ugreen charger with 2 inputs, one QC 3.0 and the other 5v 2.4A (use USB port QC 3.0)
I feel that the load is normal, but compared to the one that comes as standard, this one charges me better (I calculate that it has to set the load to 5v 2.4A, since the charger is adaptive charging, we are not going to ask much of it at an average range of 2 years ago)
As a clarification, the charging was carried out with the phone turned off
The phone didn't heat up during charging, which is good.
Well, that's all I can get out of the LG Q6's "fast charge"

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!

max with the Anker QI charger was 760mA. I use it to charge it at my office. I never cared about the charging speed A friends Galaxy S9 can use 1420mah with the same charger.

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.

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.

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?
Click to expand...

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."

Question Can we charge S21U with 40W chargers?

Hi to all,
Can we charge S21U with 40W chargers? They are a lot chargers like Huawei, Xiaomi and etc... with 40W and more.

I believe the answer is yes - or at least probably. Most of those newer chargers are "Smart" in that they only provide the volts and amps that are needed by the device being charged. I may be wrong about that, but I don't think so - I don't think you have anything to worry about.

Pretty sure you can, I use a 45 watt "smart" charger on my NOTE 20 Ultra without any issue.

You can use any charger that supports PD (power delivery), AFC or QC2.0
Any 45 watt USBC charger out there is going to be PD standard so you'll be fine.
The downside is, it'll still only charge at 25 watts.

I am charging my s21U with an 40w charger, works without problem. not using 40 watts of course, but its working.

The phone, all phones in fact, will ONLY charge at it's highest speed the phone allows itself to receive, the charger doesn't matter, it can be lower or higher than what the device is recommended for. A lower power charger will just take longer to charge the phone, a higher power charger will just not charge at it's full power if the phone won't accept the full power from the charger.
I've been using the 90w charger from my HP Spectre X360 my S20 Ultra since I got it without a single issue, I still get about 2 days of use per charge on that thing, and now I've been using the same laptop charger on the S21 Ultra and it works just fine.
The phone fast charges normally, doesn't get super hot, works just fine, and I only need to keep laptop chargers around the house, it's great haha

I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

That's the charger I've been using w/ S21Ultra (25W from N10+) and I figured out I won't be needing anything bigger then that. Thanks to Samsung 'super fast charging' the 5Ah battery on s21U charges faster then 3.8mA Pixel 4a5G battery(with the same charger). +/- 1 hour and done!
