For a while I was surprised that all of my quick charge 2.0/3.0 accessories were only pulling around 8W (9V @0.9A) when charging at any battery level (measured with a USB current meter). When I would plug into the original OEM charger, I would get upwards of 17-18W (9V @1.8-1.9A). When using "normal" USB ports the phone would pull around 7-8W (5V @1.5-1.6A). It was particularly surprising as these accessories work well on other QC 2.0/3.0 devices, and the Ultra was clearly negotiating 9V with the QC accessories but restricting the current pull.
Searching around, I finally found out that it seems that ASUS has locked down the quick charging to their own chargers:
http://forum.xda-developers.com/zenfone-3-deluxe/help/fast-charge-t3484970
http://wap.ithome.com/html/262150.htm
This is quite unfortunate for those of us who have a bunch of Quick Charge accessories that basically don't work at full speed for this phone, but even more frustrating that the phone is advertised as being QC 3.0 without any disclaimer that it really isn't because it locks out any non first-party QC 3.0 chargers to 8W or so.
The last link being in Chinese, Google Translated as follows:
9 months since the Samsung Note 7 listed since the battery accident can not help but let a lot of consumers on the phone fast charge technology security to be re-examined, according to users broke the news: earlier this month in Taiwan listed ASUS Zenfone3 Deluxe because of its starting Xiao Long 821 processor with 6 +256 memory settings by many consumers blitz.
However, some users buy the hand found that although the nominal mobile phone support 18W (9V2A) of the QC3.0 fast charge, but must use the original comes with the fast charge to open, and the remaining third-party charger can only 5V1A / 9V1A "Slow charge", even after Qualcomm certified QC3.0 charger can not fast charge, which is no doubt that those who pay attention to the speed of charging the user is very dissatisfied.
For security: ASUS Zenfone3 version of the exclusive use of non-exclusive use of fast charge
Some users complained that the online posting, said ASUS is currently not produced official QC3.0 mobile power and car charger, means out of the words Zenfone3 Deluxe can not use fast charge. ASUS official staff in the official website QA area and network forum to respond to said: the current fast-charging specifications are not uniform, the output voltage power is not the same, in order to avoid dangerous and unpredictable accidents, it is recommended to use the original charger charging. At the same time ASUS official also gives the original charger identification method:
1, only the nameplate with a lightning bolt (as shown in red box) of the ASUS charger to Zenfone 3 Deluxe and Zenfone 3 Ultra open QC3.0 fast charge, for security reasons if the use of non-ASUS original QC3.0 charger Will not open the QC3.0 fast charge mode;
For security: ASUS Zenfone3 version of the exclusive use of non-exclusive use of fast charge
2, using the original charger fast charge, the desktop battery icon will display a "+" number, while the bottom of the screen will display "fast charge" in the words.
For security: ASUS Zenfone3 version of the exclusive use of non-exclusive use of fast charge
Despite the matter in the network forum has caused no small response, in view of the current public opinion on the phone fast filling the skepticism, ASUS in various channels of the reply attitude is quite firm. There are users that buy their own official ASUS mobile power ZenPower Ultra Zenfone 3 Ultra can open 18W fast charge, the charging problem to be resolved temporarily.

I've bought a ZS550KL (5.5 Inch Zenfone 3 Deluxe) today, which supports QuickCharge also, I had a Zenfone 2 ZE551ML 4GB/64GB previously which also supported QuickCharge, and I can confirm that QuickCharge on the ZS550KL _only_ works with the supplied charger. Both the ZE551ML Zenfone 2 charger, as well as my third party QuickCharge charger do not work.
Also, and this is even more stupid, my ZenPower Pro, which supports QuickCharge too (and works flawlessly with the Zenfone 2), also does not work on the ZS550KL. This is a real pity, having QuickCharge especially on an external power bank is incredibly useful... besides, it's an ASUS product, IMO it should just work. Too bad ASUS doesn't even give us the option to override this behaviour (I wouldn't mind if it was hidden somewhere, but I just want it available).
Same problem here
The quickcharge compatibility was disabled with a certain update (I think it was the Android 7/N update). It should have general QC 3.0 compatibility with certain firmware versions. Any way to downgrade?

I recently received the CHOETECH qc 3.0 wall charger to test out and review. I gotta say I love their products. I have a fast wireless chager, a qc 2.0 power bank and the qc 3.0 wall charger. While I don't have any qc 3.0 compatible devices her, this wall charger is awesome. It's very well made, sleek, and charges as fast as the OEM charger from ssung for my note 5. Love love love CHOETECH and all their products and this new wall charger promises to be of the same great quality I have come to know and expect from CHOETECH. Highly recommended!
Picked up a Choetech Quick Charge 3.0 charger and compared w/ the 2.0. It's super convenient to charge 0-100 in no time. Quick Charge as most of you know, allow for high levels of current to flow to the battery, in an attempt to maximize its charging efficiency. Quick Charging also tend to charge their batteries at higher voltages, allowing for a higher rate of power transfer through commonly found cables. The downside to all this is that it can limit the life of your battery since they get hotter. This is the BIG selling point between 3.0 and 2.0, not necessarily charge times but battery life over the long haul. Different batteries require different charging voltages and QC 2.0 supported four modes at varying power levels, 5 volts/2amps, 9V/2A, 12V/1.67A, and a 20 volt option. QC 3.0’s uses voltage between 3.2V and 20V at 200mV increments, allowing for a wider selection of voltages.
This is useful as it reduces the amount of energy wasted during charging. Wasted energy is a big deal because all that extra power would be lost as heat. See, that's what makes the battery run warm thereby limiting the longevity of the battery's life. By having the wider range of voltage you waste less power and that results in less heat, which for you means longer battery life a year from now.
When I tried this with the Note 5, I didn't notice a significant increase in charging time but I did notice less warmth on the back of the phone. Does that prove it's working? I'm not sure but if the option exists, I'd rather try to extend my battery life if possible.

I just check Qualcomm official website. Now only Anker and Tronsmart are certificated by Qualcomm (Quick Charge 3.0) among the above brands. https://www.qualcomm.com/documents/quick-charge-device-list More and more accessories brands will release quick charge 3.0 products in 2016.
I reviewed the Tronsmart QC 3.0 you have linked in the op. It's a quality peice and even charging my QC 2.0 LG V10, it's a lot faster than the oem charger.

CHOETECH QC 3.0 18w adapter
Hi Everyone,
Just got this charger for my Note 5 ( and soon to own nexus 6P) and I love it! Its awesome to have an additional fast charge with me at work and at home. Now that I have the Note 5 and there is no removable battery I am always plugging in so having an extra Quick Charge at work is great! One of my biggest fears after reading these forums for so many years has been battery management and using the correct plug with each device that I own and with this being Qualcomm 3.0 but reversible to Quick charge 2.0 I Love it, I just carry one plug now (actually I just leave it at the office) and use it for multiple devices! I know you all know that Choetech makes a great product as I have referenced this forum in most of my decision making, and have since purchased many items form the company including the Fast Charge Qi Wireless Charging pad ( I did not get the additional quick charge cable option as I just use my Note 5 plug) but this Charger works great with the Qi Fast Charge Wireless Pad as well if you are in the market for one and if you buy them separately it is not that much more money, to me it was definitely worth it!
With that being said, your forums have helped me for many many years and I just joined and starting writing, so please feel free to let me know if I can answer any questions about this product or any product that I may have. I really love these forums, and I am very happy to be a part of them!
Thanks!
ChoeTech 3.0 Quick Charger
I had the opportunity to review the ChoeTech Quick Charge 3.0 wall charger and I have to say that I am really impressed with the upgrade from the 2.0. I’ve been using the 2.0 for about two months now and I LOVE the rate at which it charges. I would have to say that the most impressive thing about the Quick Charge 3.0 is that I get to 50% battery at bout 7-10 minutes faster than I do on the 2.0! I used to only get to about 35-40% after a 30 minute charge but with the 3.0 I am hitting nearly 50% in 35 or so minutes! Needless to say, I have been very impressed. Another feature that I’ve kind of been raving about is the fact that the USB cable can be entered into the charger block UPSIDE DOWN! I can’t tell you how often I have to fumble around in the dark before bed trying to get the cable back into the charging block (and we all know we put it in the wrong way first EVERY time) but now I just put it in no matter the direction and it just works. Not to mention, the charger comes with a USB-C cable and while I don’t have a phone that requires one, I am glad to have one as I suspect I will one day soon. I truly couldn’t ask for more! Great product, works perfectly. I’ve become a real fan of the ChoeTech products and look forward to seeing what other awesome things they come out with soon!

Yes, although S7 uses the Snapdragon 820 processor(Most other regions use Samsung Exynos 8 Octa), sadly only features Quick Charge 2.0(please check Qualcomm news:https://www.qualcomm.com/news/snapd...-galaxy-s7-and-s7-edge-powered-snapdragon-820
So I deleted all the quick charge 3.0 product links.
Since the Honor 5X uses a Qualcomm Snapgragon 616 which features Quick Charge 2.0, would it be possible to unlock this feature by software? The necessary hardware is already there...
maybe the custom kernels can do that.
I posted a similar question here. Looks like Huawei has disabled a subset of the SD616 features. Presumably this is to safe cost on this affordably priced handset. What we'd all really like to know is whether Huawei has saved cost on licenses, materials, or both. I hope it's licenses only so our devs can work their magic and unlock the goods for us.
if we can get our hands on a nandroid backup of the chinese market version then maybe our developers can port it over
I am a participant of Android 6.0 + EMUI 4.0 beta testing for Honor 5x and I have already asked Honor to implement this one in the release. I am not sure whether they would do it. I have also asked to enable OTG support with the update.
@pank.dhnd let's hope you get them to enable quick charge and OTG. thank you
Let's hope we get everything we have demanded so far
Can you enable OTG by changing the build prop line:
ro.config.support_otgstorage from "false" to "true"
and
ro.mmi.otg_test from "false" to "true"
I change the value of these 2 lines but I have yet to test with a USB drive with OTG connector.
Doesnt it support it already? My Phone doesnt charge faster with a 2-3amp charger it doesnt go over 1050ma with ampère app
http://www.androidbeat.com/2016/02/honor-5x-faq/
"Q) Does the Honor 5X support Quick Charging?
A) Yes, the Honor 5X supports Quick Charge 2.0, which means that you can charge the phone to nearly 50 percent when charged for only 30 minutes. However, do note that Huawei has not bundled a Quick Charge compatible charger with the Honor 5X, so you need to buy it separately."
According to this site it does. but I don't know for sure. I do know my phone charges exceptionally fast. The charger that comes with it is model#hw-050100u01. I'll have to measure the voltage/amp when I get home.
The Honor 5X doesn't support Quick Charge.
I have an Anker 18W Quick Charge adapter (2.5Amp) with an Anker Powerline. My phone charges much faster with that than stock charger (1Amp) and stock cable. It takes about 3 hours with the stock charger, and about 2 hours with the Anker charger.
Your USB charging cable makes a difference. Thicker 24AWG cables will charge your phone faster. I can't post links yet - but look up any micro USB Anker Powerline cables on Amazon, and a 2.5Amp Anker Charger.
https://www.qualcomm.com/news/snapdragon/2015/06/30/qualcomm-quick-charge-20-technology-explained
According to this article, we would beable to charge our phones at a maximum of 24 watts. I tested the watts on the stock charger(#hw-050100u01) and I was charging at 7 watts. 7 watts still being pretty fast, nothing compared to 24 watts. My stock charger charged at .9 amps.
So yes Quick Charge is definately disabled.
Is fast charging working with this phone?
I have belkin QC3 and I am thinking of buying this budget phone. I hope it is working even in sleeping mode.
Thanks
It seems to be a case of hit and miss so far. When I measure the charging current for the bundled charger/cable using Ampere it didn't even get close to the 2.4A current we should get.
Update: The max current I saw during charging is around 1950 mah, which isn't really considered fast charging.
Snapdragon 636 does support QC4 according to its datasheet but real life impression with the bundled nokia charger doesn't feel so quick indeed. I suspect poor charger quality is the culprit here (despite the fact it is 18W rated in specs) since no QC logo is printed on it
When plugged in, screen shows rapid chrging and cuts it off when around 80% + for battery protection I guess
If anyone charges the phone on an officially rated QC3 or QC4 charger please let us know
I also notice that the phone doesn't charge very fast using QC chargers, but when plugged into the USB C port of my (Anker or RAVpower) battery, it charges super quick. So I think USB-PD works better on this phone.
Specs wise, our phone's SD636 supports QC 4 which incorporates USB-PD standard, so if you charge on a certified QC4/usb pd charger plus the required cable, it will play fast and nice
Strange thing is that Qualcomm lists it only as QC3 device in their original device list found here https://www.qualcomm.com/documents/quick-charge-device-list as if Nokia hasn't fully enabled the chipset's feature (?) for some reason...
Well, as long you see it charge super fast, I guess you can be happy with that
I have bought this charger from Amazon.
https://www.amazon.com/Qualcomm-Certified-Delivery-Charging-Nintendo/dp/B07FQKGB9D
As Poco India says on tweet that it supports quick charge 4, i bought this up. But unfortunately i don't see a significant improvement on charging over my stock quick charge 3 supported charger. Well, i have tried different mod that are floating around in different telegram group of poco. They do help to certain degree but not that much of a difference. Why is that? Can the developer create any mod to make the quick charge 4.0 to it's full potential??
You can made a mod to increase the charging speed (in some custom kernels) but not up to the Quick Charge 4.0 standard because QC 4 has certain Voltage and Watts that QC 3 doesn't have (Let's say QC 3 up to 20w and QC 4 up to 40w)
When buying Pocophone F1, only a Quick Charge 3.0 charger is included instead of QC 4
Here is the official list of QC 4 supported devices and official QC 4 chargers on their website.

I don't really know because you bought a charger that believed has QC 4 supported but in the official list of chargers that has QC 4, it doesn't show up there. I just checked the specs of your charger and it has the highest output of 30watts. I think you just bought a QC 4+ charger.
(QC 4 and QC4+ has a little different specs or features)

Share some video if you can,like to see.Post in YouTube and give link here
One thing i noticed is that the charge never exceeds 18watts.. So that means maybe within software it's limited to quick charge 3.0..
Qualcomm has certified that Poco F1 meets the hardware necessities for quick charge 4/4+. This doesn't necessarily mean it will be able to, because it's in the hands of the OEMs that manufacture our phone. Xiaomi has intentionally kept the charging voltage to low on the Poco F1, which if provided, can be easily sorted out through software updates. But I don't think Xiaomi will do that, because it's bad for their business. If you cramp up everything on such a budget phone, there will be a decrease in the purchase of their other flagships that they have provided. So in order to keep this balance between their flagship and budget oriented devices, Xiaomi has intentionally kept the Poco F1 out of quick charge 4/4+ territory. Xiaomi did announce after a couple of days that Poco F1 supports quick charge 4/4+, but only shortly it was taken down. So don't waste your time looking up for chargers that support quick charge 4/4+, the Poco F1 will never be able to quick charge in 4/4+ if Xiaomi doesn't provide such tweeks in the phone through software updates.

Aside from the possibility of it being limited by the software, battery temperature has a major impact on how fast you can charge your device. Try watching this video: https://www.youtube.com/watch?v=Oh9OJQZinFQ
From his experiment, you can clearly see that Poco does support QC4 or QC4+ (I don't know what's the difference, but I guess 4+ is better?) and it's able to charge at a whopping 30+Watts just from lowering the ambient temperature alone as opposed to getting about 12 to 13 Watts from QC 3.0
As far as I know, there's only one charger that has worked for POCO to enable QC 4+. But seeing that this charger is nearly impossible to buy and is also quite expensive at the same time.
There is a post here in the forum I saw around a year ago where someone bought this charger and tested it. And he claims that it does indeed work.
He also did clarify that the benefits are little to none.
QC 4+ is mostly a theoretical upgrade to QC 3. Most phones don't ever reach the full QC 4+ or even 4 specifications.
We are limited by the battery technology of our time, where faster charges result in more heat. Which is why even though most phones released today are certified for 4+ they usually still ship with a 3 charger.
Other brands like VOOC are able to get so high is because they use dual battery cells.
Anyway, here's the charger if you want to buy it.

Can anyone confirm if these chargers are compatible with the rog 2? Planning on getting one.

It is interesting, but at the same time risky, if they are not compatible they can shorten the life over time, damage the battery indicating false reading on the phone, or the last thing burn you'r phone.
I would really like some hard info abou this topic!

Thankfully due to USB standards, plugging your phone into a charger that is capable of outputting more power than the phone is designed to use, will not damage the phone as it is not the charger that decides the speed that the phone will charge at, it is negotiated between the two devices and charging will start at the fastest speed that both of the devices support.
Due to Oppo's VOOC 2.0 being a proprietary standard that is only supported by select Oppo devices, if you connect any other device to the charger, it will just charge at whatever the maximum speed that can be negotiated between the two devices, which is most likely going to be 5V 2A (10W).

So since oppo owns realme it's probably using the same proprietary tech too. Bummer.
The question is whether you REALLY need those extra minutes shaved off of your charging time. Faster the charging, faster your battery deteriorates. Speaking of compatibility, I doubt you'll get anything above the 30W that Asus provides support for. I'd recommend you stick to the 18W/30W charger bundled inside, or a QC 4.0 charger.
Works fine with my old Huawei Superchargers (45W)

How faster is it compared to the stock charger?
