Does this phone support Qualcomm Quick Charge 2.0? - Samsung Galaxy A7 (2018) Questions & Answers

I have a power socket situation and I can't plug in any more adapters. I do have a USB charging hub with four normal charging sockets and one Qualcomm Quick Charge 2.0 socket. Can I use the Qualcomm Quick Charge with the phone? I have been using the normal sockets for now.

Samsung phones did not supported Qualcomm quick charge standard so A7 also, but you can use qc 2 usb cause it's compatible with standard charging.

So just for extra clarification, it doesn't matter if I use either normal USB port or Qualcomm quick charge port on the USB hub does it? They both charge at same speed?

Max current I observed during charging was something about 1400 mA so if usb support it than should be the maximum speed you can charge your phone. So yes if normal 5V USB charger support up to 1500 mA than it will charge as far as qc 2.0 capable.

In my experience even without quick charge support it will charge much faster using a quick charge 2.0 charger as long as you don't use some cheap cable or the Samsung cable.
Use a proper 2.4a quality USB cable(these are noticibly thicker) . Combine this with the quick charger and you'll see a marked improvement in charge times.
I have seen my J3 reach charging currents of 1.9a using a Quick charge 3.0 charger and 2.4a cable vs a max of 1.2a using the Samsung cable and much lower using el cheapo cables.
Charge time for me is an hour from almost empty to full.
All my devices have shorter charge times using this arrangement.
Trust me the cable makes a worthwhile difference.

[Q] Is Sony Z3 Quick Charge 2.0 compatible?

As per my title, can anyone confirm if the UK version of the Sony Z3 D6603 is Quick Charge 2.0 compatible?
If so I can't find a Sony Quick Charge 2.0 adapter either?
Many thanks,

Hello figo_rulz,
I can comfirm that the Sony Xperia Z3 D6603 has Quick Charge 2.0 built in, as the Sony Xperia Z3 Consists of the 'Snapdragon 801 chip' which is believed to hold the Quick charge 2.0 Capability (You can also check on their website: https://www.qualcomm.com/products/snapdragon/quick-charge)
Sony sells a 'Quick charger' also here's the link listed below:

Is it definitely all Z3's devices? Reason i ask is i heard it's just japan versions which support it.
do you know where you can purchase a UK 3 pin adapter ?or a better alternative adapter?

So just reading up and it seems EP880 adapter which is what all UK Z3's have is what the adapter also is with the EP881. The only difference is actually the cable as this has two ferrite cores which prevents interference and the EP880 has none. so ideally I would just need to look for the cable as my adapter is capable of this quick charging 2.0! Apparently the cable we have is the EC803 without the two ferrite cores and the one you need to enable quick charging 2.0 is EC802!
The search goes on for the cable!
I use my note 4 quick charger and it works
How fast is it?

Despite of what Sony says in this link:
http://talk.sonymobile.com/t5/Xperia-Z3-Z3-Dual/Quick-Charge-2-0/m-p/973745#U973745
I have tested different chargers and came to the conclusion that Quick Charge 2.0 does work with the Xperia Z3 (at least with my variant, the D6633). I could verify that I have happily charged my Xperia Z3 from 10% to 100% in a little less than two hours, using a Motorola Moto Maxx (Droid Turbo) charger, which is a charger with Quick Charge 2.0 technology.
Moreover, I have also verified the charging currents with the Battery Monitor Widget app, and noticed that using different chargers can drastically change the charging speed of our phone.
I am going to take some screenshots tonight when I put the Xperia Z3 to charge and then upload them here tomorrow.
SONY Quick Charger EP881 is NOT QC2.0 compatible/certified. I own one & shipped charger seems better but I hv no clue why.
OK, here are the results for my charging.
Up to 40%, I have recharged my phone with a Moto Maxx (Droid Turbo) Quick Charge 2.0 charger, then I changed to the stock/original Xperia Z3 "quick" charger (EP881), which I have no idea why is named "quick" charger by Sony...
Notice the Moto Maxx charger got me a 1600ma/h charging, which would charge my phone in about 2 hours. The EP881 Sony Stock charger got me around 900ma/h charging. That would led me to a total recharging time of more than 3 hours.
I still could not test different Quick Charge 2.0 chargers, but I can assure that the Moto Maxx/Droid Turbo one DOES work with the Xperia Z3.
It IS QC2.0 compatible, HOWEVER: The charging setup is such that you'll only see a benefit in cases of charging while the system is under load.
The Z3 kernel limits battery charge current to 1.5A (approximately 0.5C) regardless of what charger is attached.
If you attach a non-QC2.0 charger with a VERY high quality cable (less than 3 feet with 24 gauge wire or thicker), you'll typically see 1.5A of battery current WHEN THE SCREEN IS OFF. Even in that case, you won't see consistent 1.5A input into the battery (use CurrentWidget)
Turn the screen on and you will NOT see 1.5A of current going into the battery with a non-QC2.0 charger, as the battery power in is (Vbus input limit - system load)
However, if you have a QC2.0 charger, even with a thin USB cable that would normally lead to extremely poor charging performance, you'll see 1.5A go into the battery under almost any load condition.
TL;DR - It's QC2.0 capable but you'll only see a difference when the device's screen is NOT off. If the device is plugged in to a high-quality USB cable and the screen is off, you'll see only minimal differences.
You'll see a MASSIVE difference if you use one of these cables - http://www.amazon.com/StarTech-com-Micro-USB-Cable-UUSBHAUB3RA/dp/B001AR4NC8/ - These cables aren't particularly good for charging with a standard charger because they're thin - but that same "problem" makes them good for connecting to a phone in a car mount. (I cannot find heavier-gauge cables with a right angle connector). If you use a standard charger with them, you'll find your battery draining with Google Maps Navigation. With a QC2.0 car charger - the battery will actually charge while running Navigation.
I've confirmed QC2.0 functionality with a Tenergy wall charger, a Powermod car charger, and an Aukey external pack. The Tenergy wall charger is nice in that it has an indicator light - blue if in "standard" 5v mode, green if in 9v or 12v QC2.0 modes. Sony's stock chargers are NOT QC2.0 capable.

I find it interesting that you say this, because even with the phone left untouched I can't even get 1.0A charging with the stock charger and stock usb cable. As I have shown in my post before, I get a 0.8 to 0.9A charging, and yes, the screen is off. I have not touched my phone during this time at all. What can I conclude from that? Isn't the stock usb cable good enough?
Moreover, if this limit is set the by Z3 Kernel, it is possible to edit in the stock kernel, isn't it?
Regards.

In my case, I was using a Samsung tablet charger. These actually increase their voltage slightly under load to compensate for cable losses. I forget what Sony's stock charger is rated - but if you're only seeing 0.8-0.9A, then it might be on the weak side (just like the 2012 Nexus 7 had a weak charger). I pretty much exclusively use Anker multiport power supplies and either Monoprice or Anker heavy-gauge (24AWG for Monoprice, supposedly 21 for the Anker, lower is thicker/better here) cables.
A QC2.0 charger makes the cable selection FAR less important - transferring a given wattage requires less current at 9V than at 5V, which leads to less resistive losses in the cable. Same principle as why power grids use hundreds of kilovolts for long-haul transmission lines.
Yes the kernel could be altered, but since the battery is nonreplaceable, few responsible developers are going to do it. Heck, sony AOSP currently disables the HVDCP service due to paranoia about ensuring that ALL battery management protection mechanisms are in place before turning it on in AOSP. (I am fairly certain they ARE all there, but I want to do some more digging.)
HVDCP?what is that?so if the kernel is altered then quick charge 2.0 can be used?so now my z3 d6653 can only charge a maximum current of 1.5 A?

HVDCP - High Voltage Dedicated Charging Port - I think Qualcomm is actually attempting to get QC2.0 standardized (they're already licensing it to non-QCOM OEMs - the Galaxy S6 supports it, as does NVidia's SHIELD Tablet, NV doesn't market the capability AT ALL but it's there!), so there are lots of references to naming conventions consistent with the USB Battery Charging Standard
DCP - Dedicated Charging Port (dumb wall charger)
SDP - Standard Downstream Port (PC port, limited to 500 mA)
CDP - Charging Downstream Port (PC port, allows for higher current) - Android device support for CDP detection is pretty rare, lots of kernel developers will risk damaging SDPs by simply forcing CDP behavior from an SDP
Even without kernel alterations, Quick Charge 2.0 is used - Quick Charge 2.0 is defined as delivering 9v or 12v from the wall to the device in order to deliver more power. It's up to the OEM whether to dump more of that into the battery, or simply to use it to allow for higher total system power. Without QC2.0, the Z3 can only charge at full rate in the absolute best of circumstances (screen turned off, even then it doesn't always reach 1.5A) - with QC2.0, the Z3 can charge at full speed even with the screen on.

Yes, it will charge faster.
How much faster depends on what you're doing. If the device's screen is off and it's idle, only a little bit faster.
If you're running Google Maps Navigation in a car, the difference will be massive. As in "charging at a decent rate vs. discharging despite being connected to a power supply".
It will charge in around 130 minutes with QC2.0, and around 210 minutes with the stock charger (EP880).
At least that's how it works for me.

Qualcomm Fast Charge 2.0

Hi, does someone know if our phone supports Fast Charging 2.0? I'm from Europe and there is no charger added to the phone. I searched and found an UCH-10 charger with Qualcomm Fast Charging 2.0

No I don't believe it does. It's a shame since the Snapdragon 410 supports it, but I guess Motorola wanted to save a few cents.
But maybe it supports quick charge 1.0

Yes, it does support QC 1.0.
But QC 1.0 doesn't really speed up charging like QC 2.0 does (max. 10W vs max. 60W).
I have a charger from my old Xperia neo V, but it's to week ( only 870mAh ), the phone has in 5-6 hours 100% of battery and the charger is getting sometimes very hot.
Motorola doesn't included a charger ( only a USB cable ) in the package due to EU regulations.

About quick charge

HELLO GUYS
i just got the tronsmart quick charger and remax type c cable
i see that its charge my xiaomi mi4c a little bit faster then the original one but theres not big diffrence
i tried on my girlfriend lg g4 and the charging is really fast
i think that xiaomi has built in limit for the charging
any idea what to do to skip that limit?
Until xiaomi releases kernel source code and a custom kernel is developed, nothing can be done about the charging limits (which is true and tested). I used the same charger to charge my HTC M8 and it has quick charge compared to the M8 original charger.

There's a good reading material here: https://forums.oneplus.net/threads/charging-analysis-between-oneplus-2-and-xiaomi-mi-4c.387573/
I'm not sure whether it's kernel controllable or not, but even if yes, we need the kernel source to modify it.

From what I have understood, the original cable that came with the MI4c is a modified Micro-USB type B cable, and not a "real" USB-C cable. So your (and my) MI4c phone draws a maximum of 5V~2A from the original charger and the standard USB-C cable, whereas the LG G4 draws a maximum of 20V~5A from the USB-C cable. This means that the LG get more power, faster from the USB-C cable you bought, and therefore gets charged faster - and you will not notice a big difference when using the USB-C cable, as your phone only draws the mentioned 5V~2A.
Do yourself a big favor, and throw away your original cable from Xiaomi, as it might potentially break your charger, laptop etc. if you use it in your girlfriends phone!

Good to know... I just assumed there was USB-C type cable to the G4 as OP apparently were able to charge the phone with a USB-C type cable.
OP must have mixed up the model name of the phone, then.
Hi, I tried an Anker and Aukey quickcharge wall charger with some issues...I used till now the original battery charger with its usb cable. I usually charge the phone turning it off... When it gets to 100% I unplug the phone and then turn on .. that's normal ok... But I noticed that using another compatible charger that uses Qualcoom 2.0 quick charge technology.. once the phone gets 100% and I unplugg the charger my phone boots by itself.. Why does it happen with this charger and not with the original one???

Fast charger for LG G5 ?

Hi there,
I have got the LG G5 in excellent condition but there is no charger with it so i needed to buy original charger which i was struggling to get in uk. Is there any others charger which charge as fast as original. I am not sure which one to buy. Can you guys check thsi one and tell me if its any good

I did use some power banks made by this company. And everything was always all right. So in my opinion you can give it a try pal.
I have also a question about original wall charger. Does it support qc 3.0? Or it's just a 2.0 model?

I dont have orignal with me but it should support QC 3.0 because they say that 80 percent charge in 30 minute. How long it take for you to charge your phone fully?
80 percent in 42 minutes. That's why I think it might be qc2.0

Looks like LG changed something starting with v10d - 3rd party chargers still fastcharge but you need the original LG cable or all you'll get is slow charge.

Just for everyone's info, g5 will say fast charge even if you charge it on qc 2.0. There should be some notification saying is it 2.0 or 3.0 , ampere and apps like that meassure only mah, but we need measure V cuz qc 2.0 and 3.0 are not 5v

And mind that quick charge wont work fully with the screen on, as it automatically decreases the charging power due to heating.
