the latter also allowed me to fastboot oem unlock.
so battery is at 59%, homescreen says 14 minutes till full.
cheers
can you please check with Ampere or GSAM for the charging speeds that you achieve?
does the device say fast/rapid charging?
Interested to hear the results from Ampere or GSAM as well
i cant get a good handle on how ampere works. it keeps measuring, takes forever, and fluctuates a lot.
with the aukey combo, i got 1830/2050mA @ 4.14v, at 53%, 37.7c
took it off charge for a while and tried again with the stock charger:
with the stock charger, i got 1850/1860mA(min/max) @ 4.159Vat 61%, 30.7c
I will try again at 50% today if I have time but I am pretty pleased with my little aukey combo. It was cheap.. I got it when there was a 7 dollar coupon floating around.
FYI, believe this is the same charger : http://www.amazon.com/gp/product/B00QEX83LA/

Yep that would be the one. charging at 1800mA is not the fastest that the phone can charge at though. I'm going to hold off for the ones that enable the full speed of charging

For 7 bux I think it's still a good deal for someone who doesnt have a spare to use
From the product description, you are only going to get 2A out of the charger. 5X doesn't do QC2.0, so you will only get the output at 5V, which for this charger is 2 amps.
Specifications:
Input: AC 100-240V
Output: 5V/2A, 9V/2A, 12V/1.5A
Dimensions2.69*2.05*0.87in)(68.5*52*22mm)

But some Aukey chargers with AIPowertech like this one "charges all non-Quick ChargeTM 2.0 phones and tablets at their normal speed (up to 5 volts / 2.4A Max)with AIPower Tech Technology."
I've got the charger, just not the cables... so haven't been able to test.
I tested Aukey PA-T2 wall charger QC2.0 port ( orange one) on a Sony Xperia Z3 compact tablet
I recorded charging current up to 2.7Amp with the Aukey USB cable and up to 3.0 Amp with the Sony USB cable !!!! far more than the 2.0 Amp level current Aukey specifies......
The voltage - current output test show that the voltage stay in the 9.0V range with current up to 2.4Amp then fall down very quickly. It seems that the voltage stay at a value enough to deliver up to 3.0 Amp charging current to the tablet ....
Detailed test are here (http://78michel.unblog.fr/?p=860 in french....)
Current values where obtained from BMW recordings

LOL, thanks... but that doesn't really help this 5X cause. Given that there is no quick charge on the 5X, it'll remain at 5V. The question is whether it'll pull more than the 2A or 2.4A specified on these chargers at 5V on a 5X.

Aukey quick charge 2.0 behave like a standard charger when connected to a non QC2.0 compatible device. The output voltage will stay to 5V so the current level will be very sensitive to the quality of the USB cable and limited by the maximum current the device will afford.
In practice it is very difficult to reach 2A charging level ( even if the charger is able to deliver such current) with a voltage output of only 5V , due to losses in cables and connectors
From my experience the higher current charging level I obtained was with a Samsung wall charger refence EP-TA10EWE which deliver an output voltage of up to 5.5V at 1.9A ( nominal voltage is claimed at 5.3V)
I got 1.7Amp charging current on my Nexus 5 while with the Aukey QC2.0 the current was only 1.1 Amp in exactly same conditions ( these recorded data are also reported in my blog .....in French.....)

Thanks, didn't think to look at the link.
I wonder how older phones like the NA Galaxy S3 and Nexus 4 that both have QC1.0 ([email protected]) compare to the charging of the Nexus 5.
I'm curious as to how you did your testing, as I'm going to try my own testing once my cables come in. Did you drain all your phone's battery to 0 before performing each test? Phone airplane mode vs off? I also think that all tests must be done in relation to time, especially since the charging profile changes as the phone charges. I'm also curious as to how the non QC port on the Aukey performs, since it's spec'd at 2.4A @ 5V.

All tests are made with battery drained to zero before starting , and a complete charge is done in each conditions. That way I can check that the full charging time is logically related to the recorded current values. The current is recorded during the complete cycle at a frequency of one value per mn.
The air plane mode was off.
Aukey QC port and non QC port are slighly differents when connected to non QC2.0 devices :
QC port delivers 5.1V in open circuit, the voltage encrease to 5.2V at 2.2Amp, on the contrary the non QC port delivers 5.2V in open circuit and decrease to 5.1V at 2.2Amp. I did not test them at higher current level.
I did not tested Galxy S3 or Nexus4 , but I beleive that a charger like the Samsung EP-TA10EWE will deliver them the maximum charging current they are programmed to accept, as obeserved for the Nexus 5.
I got the same charging current curve I recorded with Nexus 5 and Samsung EP-TA10EWE, with other set of charger and cable. This means that this charging curve is defined by the Nexus 5 inner program , not the charger characteristics. The problem is that we never know which is the max current curve internally programmed for each smartphone...... so it could be a long way to find it.......
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

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!

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?

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.
This phone supports 21w charging, but it is only shipped with an 18W charger. (This charger seem to be able to give out 5V, 9 V (2A) and 12V (1.5A).)
Anyone have information on what version of USB-PD the phone supports? And what voltage is used to obtain 21w?
Has anyone got 21W charging working? As not all higher wattage usb-pd charges may support the 21W mode that this phone needs.
Well I can tell you do not use anything above Sony's recommended charging °W because anything above that - even with PD -- the device will intensely heat up.

Sony report 21W charging. So I'm not asking to go above Whats recommended.
I am asking more about the actual charging methodology, as the usb-pd system can be a bit complicated. And even a 45W charger may not correctly 'handshake' at 21w unless it's got the right voltage to offer.
Anyone?
No one has tried using a higher wattage PD charger?

My Xiaomi 30W 1A1C charger (which supports USB PD 2.0 over the C port I believe) negotiates 7V/3A to hit the 21W.

Me too, I thought it'd be doing 12V/1.8A or something but 7V/3A makes sense. Definitely should make sure the cable is quality enough to support 3A. As an aside, the phone charges at 5V/1.5A for all non USB-PD compliant chargers.
I measured with a super cheap USB C meter that I've been sticking into random chargers for curiosity sake. Highly recommended :laugh:
Ok, ordered an Usb pd 3.0 charger today, the Arcanite one. As it also has a PPS option.
Also ordered as usb c power meter.
Let's see if it does the same voltage combination with this charger.
I just looked more into the USB-PD spec and I believe you'd need a PD3.0 compatible charger to hit the 21W since the charger needs to support PPS to hit 7V/3A. Otherwise I'm assuming it would negotiate to 5V/3A or 9V/2A if the charger doesn't have a 7V step.
So got a charger with PPS support (a USB-PD 3.0) an up to 30w charging. An Anker USB c to c cable with 60W support.
And using a satechi voltage / current measuring device.
But something isn't correct. It could be the usb-c voltage measure.
Using the supplied 18W charger, it's displaying 5.27V, 2.78A. that's roughly 15W. ( Picture attached).
Using the new 30W charger, it's displaying 6.44V, 2.77A. that's roughly 18W. ( Picture attached).
Still need to do more testing, not sure why I'm getting these readings. A bit below what I was expecting.

What battery % is your phone at? You also have to remember that the closer the phone is to 100%, the charging speed will slow down.
I have an Anker 30W charger and can charge at speeds of at least 3500 mAh (based on Ampere reading).
The battery was around 35%. Yes you are right once it got over 50% the charging rate does show down a bit.
Also the Ampere app was displaying 3600 or 3500 as the current. But even if we calculate that, that's only about 18W. But that app isn't very good at measuring charging voltage or current.
The charger's specifications are attached below,
Actually, did anybody find a 21W charger compliant with our device??? (I mean really delivering 21W...)
Edit:
I've ordered the Samsung Ultra Fast Charge 25W (ref: EP-TA800XBEGWW)
It is PD 3.0 PPS and delivers 3.3-5.9V at 3A or 3.3-11.0V at 2.25A.
I hope that will work...

I have the Samsung EP-TA800 25W charger from a Samsung Galaxy A71 5G. On low battery with my USB tester, I measured 22W (9V/2.5A) when charging my A71 but only 15W (5.5V/2.7A) when charging my Xperia 1 ii. Were you able to do better with this Samsung charger?
In fact, I have been testing all my PD chargers (about a dozen in total -- I might have a problem!), and none has been able to charge my Xperia 1 ii at more than 18W. That's certainly decent, but it would be nice to get the 21W that the hardware is capable of.

Both Sony charger 18W and Samsung EP-TA800 25W charger take 37 mn to charge from 20% to 70%. So, the extra power of the EP-TA800 cannot be used by our device, it does not provide the correct electrical intensity...
Finally, I've ordered the ARCANITE Premium PD 3.0 QC4 PPS 30W charger as mentionned above.
I've received the ARCANITE Premium PD 3.0 QC4 PPS 30W charger and I've done the tests.
To charge from 20% to 70%, the Sony charge takes 37 mn and the ARCANITE charger takes 36 mn (tests done in aiplane mode).
The small difference occurs below 50%.

Thanks for the update. It seems like the ARCANITE might not be delivering the 21W as hoped.
I also ordered yet another charger, the Baseus BS-C915, which allegedly supports PPS. The PPS designation appears in some pictures, but the specifications describe only a range of voltages (3.3-11V @ 3A).
With the Baseus, I get just under 18W (6.6V @ 2.7A) when charging my Xperia 1 ii. It's kind of strange that Sony claims 21W charging but doesn't include a 21W charger and doesn't even provide the specs for one!
So I have a 45W charger, thinking about purchasing a 65W charger. I know The Tab S8 Plus only goes to 45W.
My question: are there any advantages to using an emark enabled cable?
I'm getting super fast charge notice with a 60W cable, no emark.
In my google searches, someone mentioned you can get "super fact charging 2.0" if you use an emark cable. Other pages said you only need emark above 60W. I found this comment on one site "... the Samsung Note 10+ or S20 Ultra which supports 45W fast charging. With these devices, the maximum electrical current is 4A, therefore it also requires a 5A cable with E-Mark. "
Does anyone know the ins and outs of this?
Thanks,
Joe
Get the recommended Samsung OEM brick and use the cable that comes with it. For the N10+ the 25w brick/cable fast charges fine and lasts for years if you don't roll up the cable.
Charging issues are hard to troubleshoot and non OEM bricks/cables only add to that burden.
At $20 a pop the 25w brick/cable is a no brainer.
So I have managed to answer my own question:
With a normal 3.1A US0b-C to USB-C cable, my 45W power supply is throttled back to 25W. It is reported as "Superfast Charge" mode by the tablet. Using Ampere, it reports that the battery is being charged at 5A at 4.2V --~ 21W
I bought a 100W E-Mark cable, and it now reports "Superfast Charge 2.0" -- and now Ampere reports it has bumped up to 7.5A at 4.36 V. So it is bumped up to 32W. Still not seeing 45W, though.
So it would seem to be charging 50% faster with the new cable.

do you know what is happening here?
I don't have any information to illuminate what's going on, but this sounds familiar enough that I think at least one or two other users in this section have reported something similar. Me, I try not to quick/fast charge any more than I have to, and I keep my battery between 25 and 75%, so I don't pay that close attention.
I haven't used Ampere. I assume the top is the charging current? The one on the left shows a higher current, 5.58 amps, vs 4.40 amps. Higher current for a given voltage means more power is being transferred, thus a higher charge rate...but even 5 amps is pretty high. That's why fast charging schemes use higher voltages, because a given conductor can usually handle a higher voltage better than it can handle a higher current.

The Galaxy S8 is advertised to be able to charge at a 45 watt rate, max, so if this is true, a 100w charger wouldn't charge any faster as both devices would negotiate a max of 45 watts. This is assuming both the device and the charger limit the charge current; I imagine many devices will draw more power than they're rated, and many chargers will try to supply it, although the load might pull the voltage down.

the other photo is from the 25w samsung charger that came with my ultra
so i dont know why the tablet is showing the same time to full charge

I don't have any information to illuminate what's going on, but this sounds familiar enough that I think at least one or two other users in this section have reported something similar. Me, I try not to quick/fast charge any more than I have to, and I keep my battery between 25 and 75%, so I don't pay that close attention.

Do you have the text super fast charging 2.0 when charging your tablet?
I don't

Probably because your tablet can't charge at a rate any higher than 45W - 15v @ 3 amps.

That is correct it can only take 45w so 100w won't work. It will only limit the 100w charger down to 45w

hi with my ultra i got a free 25w samsung charger
i bought a 100w ugreen charger :
ingle-PortUSB-C1/C2：5V/3A 9V/3A 12V/3A 15V/3A 20V/5A 100W Max
USB-C3： 5V/3A 9V/2.5A 12V/1.88A 22.5W Max
USB-A： 4.5V/5A 5V/4.5A 5V/3A 9V/2A 12V/1.5A 22.5W Max
with a cable 100 PD
when connecting my tablet says same time to charge 100%
and ampere app shows this photos View attachment 5659897View attachment 5659899
do you know what is happening here?

You shouldn't look up what a USB port can take. It also depends on what main board and battery can take. In this case s8 ultra is limited to max 45w. So your 100w charger won't go 100w on this tablet because it does not support it.
the charge circuits are limited to a max input wattage and voltage. to protect the device from being burnt out. it is not like the good old days where you could pump as many watts and volts you wanted into a device hoping that you didn't burn it up, blow the fuse or a diode. now everything is limited to a max input. a lot of it has to do with the brand x / universal chargers being sold. that claim they charger faster when really they don't.
The question is not about 100w
it is about 100w doing 45w vs 25w charger and same time charging

I don't know. They're both charging at about 5 amps which is honestly pretty high. Nothing indicates the actual charging rate in watts because it doesn't display the charger voltage. I will say I'm rather skeptical of strange off brand Chinese tech so it's possible you'd get better results with a different charger.
Question is neither is showing super fast charging 2.0
Fast charging is on in settings. It shows super fast charging but not 2.0
I got the same issue with my s22 ultra...The charger must have the right specs and the cable must be 5a. If not, you won't get super fast charging 2.0. This will only give 25w fast charging. I have a 65w ugreen charger that has all the right specs...It has 65w max on 1 port and when other devices are connected on the other ports it distributes the 65w over the ports. I used the cable that came with the tabs s8 ultra and got the same as you, not charging to it's full potential. Bought a ugreen 5a cable and now it shows super fast charging 2.0 on my tab s8 ultra and s22 ultra. The charger and the usb cable must be 100 % correct, otherwise you won't get max charging speeds.

i have the ugreen 100w charger with the 2m pd100 5A cable ( it says 5A in the end of the cable ) that came as a pack in ali but not seeing super fast charging 2.0.
Mine was exactly the same. Bought a different ugreen cable and the 2nd cable worked. Dont know why it worked. Looks the same as the one that came with the charger, just a longer cable

The cable makes absolutely no difference in the actual charge rate. Being rated for higher current just means the conductors are larger.
When you connect the device to the charger, the two negotiate a mutual rate.

Superfast charging + emark cables -- are they needed?
So I have a 45W charger, thinking about purchasing a 65W charger. I know The Tab S8 Plus only goes to 45W. My question: are there any advantages to using an emark enabled cable? I'm getting super fast charge notice with a 60W cable, no emark...

If you have a normal 5A cable, all PD charges are throttled to 25W (or less). Your tablet (at best) will show "Super fast Charge" and you will see something like 5A @ 4.12V when running Ampere. This is the power going into the battery -- the PD Charger is probably delivering something like 4A @ 5V. Around 20W going into the battery. I assume the "missing" 5W is powering the tablet - i.e. Ampere only shows what is going into the battery.
To get more than 25W, you need special "e-mark" chipped cables. These allow current higher than 5A to be delivered. They will be generally be rated by power -- 100W -- not current. I use
https://www.amazon.com/dp/B09G5XQG3T
This will allow the PD charger to run higher than 25W and you will see "Super Fast Charging 2.0" for charge status.
When I use the 100W cable, the tablet charges iin "Super Fast Charging 2.0" mode, and Ampere tells me the battery is receiving 7A @ 4.12V, or ~ 30W. Because I'm using the tablet at the same time I again assume some additional power is going to powering the tablet -- but that Ampere is only showing what is going into the battery. So maybe this bumps it up to 35W total. I have 45W and 65W power delivery bricks, so I assume the ~ 35W-ish delivery is being controlled by the tablet.
Note: The cable "in the box" with my Tab S8+ was NOT chipped, and was limited to 25W.
take care,
Joe
