Find this interesting charging analysis from here, and thought i should share!

We just report Xiaomi Mi 4c information today earlier. Now, Let’s check the charging performance on Xiaomi Mi 4C.
Because our test sample is still on the way, should get tomorrow, the following test result are coming from our friend @chongdiantou, All credit to him
Here is the usb type c port in Mi 4c, and you need to connect your charger via type c cable to charge it.

Here is the type c cable which included in the package, the length is about 1.2m.
Xiaomi also include a USB TYPE C Adapter in case you forget to take your type c cable, and you can connect this adapter with your Mi 4c, and use the regular usb cable to charge your Mi 4c. But it is really NOT convenience for people to charger via the adapter.
Here is the photo for the stock charger in xiaomi mi 4c:
This stock charger model is MDY-03-EB, input is 100-240v, output support 5V/2A, 9V/1.2A and 12V/1A, total 12w. It’s follow the qualcomm quick charge 2.0 standard, however, the total watt is lower than ours’ 18W quick charger. and this is the same charger as you seen on Mi3 and Mi4 and Mi note.
The sample we test still use preload MIUI 6, and the battery level is 60% when we do the following test.
First we test with the original Mi 4c charger, with screen on, we get this;
With screen off, we get this:
With screen on,you get 9V/1.12A, and with screen off, it change to 8.98v/0.99a, it’s a little surprised, in our charging analysis for Oneplus two, we found if you turn off the screen, the charging current will get bigger, while in xiaomi mi4c, it get smaller.
Update: We just found this charging time test from another site:
They use the original xiaomi stock qc2.0 charger, and It need about 2 hours 10 mins to charge from 8% to 100%.
Then, we use the xiaomi ZMI QC2.0 charger to test:
The ZMI qc2.0 charger have the same output as ours, 5V/2A, 9V/2A, 12V/1.5A, total 18W. However, the mi 4c also just accept 8.96V/1.16A.
So we can confirm xiaomi mi 4c make some current limits.Now we can’t know the limits are in kernels or the hardware.
Since no matter which quick charge 2.0 chargers you are using, the output just almost 10w, how about to try the regular 5V/2A charger? Then, next, we decide to test with Oneplus two charger:
Oneplus two offer a 5V/2A regular charger, In our charging analysis, it can give 5V/1.98A to OPT. so what’s about in the xiaomi mi 4c?
Even the charger can offer 5V/2A without problem, but xiaomi 4c just accept 1amp current. So If your charger don’t support qc2.0 quick charge, it can just give 5W output to xiaomi mi 4c. This is really annoying. we don’t understand why xiaomi limit current in 5V/2A regular power adapter.
Here is the first part of Xiaomi MI 4c charging analysis, we will test the total charging time from 0%-100% and compare with our tronsmart qc2.0 chargers. and will try to find the reasons why xiaomi limit the current.
But now, from the analysis, If you want quick charge your Mi 4c., you have to get qc2.0 chargers.
Xiaomi have one wall charger included in the package, If you want a backup qc2.0 wall charger, you can check our WC1Q model:
http://www.tronsmart.com/products/ts-wc1q-rapid-wall-charger
We also have multi-port QC2.0 chargers, check here:

Hi, I have Mi4C... and I have a "problem", I tried Anker and Aukey wall charger using quickcharge 2.0 technology.. But I had some issue.
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???
As I don't have any measurement tools, I can only state things based on my observation, but I see no noticeable difference between charging time using xiaomi's charger and a noname 5V/2A charger - ie. in both cases an idle phone (system on, wifi on, standard processes running in background) gets fully charged in about 2:15 to 2:30. Currently I'm on holidays with a standard 5v/2a charger, using some cheapo usb A to micro-usb, a noname microUSB-usbC converter and charging time remains the same every time I charge. Most probably the results may vary with different cables - maybe in some cases the charging power is purposely reduced by phone electronics in order not to fry the charger if it's get recognized as regular one.
I also use a car charger that's capable of 5A/1A and charging there lasts ages; never drove sooo long to get the phone fully charged
I tried a Lumia usb charger 5A/750mA and then it takes about 5 hours to get mi4c fully charged
regular users - try Ampere app, it works well, at least with CM12.1. the one shows charging at about 1400-1500mA with the above mentioned setup,post your results with different cables / chargers
for me guys xiaomi mi4c didin't have quick charge.
I have note 4 and he have battery 3220mAh (thats mean bigger should take longer to charge) and even when i use him (have bigger screen loosing more energy) and i charge from around 20% i see my procentage of battery is growing. With xiaomi almost nothing....
But ok lets speak about quick charge.
Qualcomm® Quick ChargeTM 2.0 Tech
Developed by Qualcomm, the proprietary technology solution is built into devices powered by Qualcomm® SnapdragonTM processors, including the 200, 400, 600 and latest 800 series (including 810). With a compatible phone, laboratory tests show that Quick ChargeTM can charge a typical 3300mAh mobile battery from empty to 60%-75% in as little as 30 minutes.

then sorry guys but in 30 min u have nothing in xiaomi.
i like this phone but about charging is not like should be
I can vouch the included charger is crap. It vibrates on trickle charge and it doesn't charge much faster than a regular 2A charger.

I don't know what's faulty on yours. Mine can reach 60% in 1 hour with the supplied charger and cable.

Sorry but meybe u didint see but quick charge 2.0 means
30min =60-75%
your is
60min = 60%
THATS MEANS FOR U IS QUICK BUT FOR REAL HOW SHOULD BE IS TWICE SLOWER
Im not telling like charging is crap just i have note 4 6 months and charging is much quicker... thats all....
And start to play some games on xiaomi when u have 20% and than tell me how quick u will charge your phone.... Meybe for u is quick because u never had before real quick charge 2.0. I had samsung galaxy s5 and was normal but after when i bought note 4 and i was plaing on phone and the same time charging my battery was really fast charge to 60-70%

You're drunk, even Qualcomm never admits that. Here's official Qualcomm video:
https://www.youtube.com/watch?v=Ut6lemu_N64
It uses Nexus 6 which has 3220 mAh battery. The snapshot takes:
20 min -> 26%
30 min -> 38%
40 min -> 50%
Compared to my 60 min -> 60 %, the progression looks comparable. Now state a prove for your claim.

I wouldn't do that. Why charging while playing on low battery? That could definitely kill your device if the wrong thermal config is used because the device will get really hot compared to if you do it on >50% battery. It seems like you're the one who doesn't understand how to charge correctly.
Ok u have official information but me to....
https://www.qualcomm.com/products/snapdragon/quick-charge
Then u see they write every single page different things...
And about thermal things i go to work 2 hours in work i use phone as vell then sorry but i have only time on breake to charge him and than i have 1hour time for me then if i like i play.... I canot think like i will broke phone. Phone is to help me in life not to watch because i can break.... IF i break i will buy new... Anyway i change them minimum once per year... Im not telling like not 4 is perfect because to be honest xiaomi is much quicker... Only camera and that charging was better...
For whatever reason Xiaomi limits the charging on this device. Quick charge 2.0 according to the official qualcomm specs is 0-60% charge in 1hr. I can only get 0-40% charge in an hour. Without the kernel sources, there is nothing that can be done to modify the charging rates. Anyway, using the charger that came with the phone, I can charge from 0-100% in about 2 hrs and 15 mins which is good enough for me

You might want to scroll down a bit and read:
Remember, a Quick Charge 2.0 certified power adapter is required to charge at the speeds Quick Charge 2.0 is designed to allow. Different Quick Charge 2.0 implementations may result in different charging times.

Also check https://www.qualcomm.com/documents/quick-charge-device-list, Mi4c is clearly listed (on page 2) and thus certified by Qualcomm.
I know xiaomi says 2.0 but only what i try to tell u quick charge compare to my note 4 is not quick....
What i try to say its good to tell to people quick charge 2.0 are sometimes completly different...
I was thinking when i was buing that phone will be the same like note 4 but is big different.
And IF somebody thinking about buing this phone he should now its not charging in 30min 50% of your battery
I was trying note 4 charger and xiaomi charger and now i order this one
http://www.ebay.com/itm/281867423580?_trksid=p2060353.m2749.l2648&ssPageName=STRK:MEBIDX:IT
And how u see supouse to charging in 30min and i understand couple % less but that not working how should
It is working how it should, because it is working the way the manufacturer calibrated it to. All hardware is different.
You can't expect everything QC 2.0 to charge at the same rate of 60% in 30 min or whatever. If only because 60%/2000mAh is half of 60%/4000mAh for instance and rates will differ depending on the current capacity etc etc.
Is not point to argue anymore just i tell u only
Note 4 have 3220 and xiaomi 3080mah thats mean is not big different thats why i supraised.
What i know now in Samsung quick charge 2.0 works much better than xiaomi quick charge 2.0.
Reseting charger when it overheats (?)
I had an interesting experience with the Xioami Mi 4c charger when on a recent vacation in South East Asia.
I purchased a 4G (LTE) sim for the vacation and I was extensively using the phone as a wifi hotspot for my wife and my other wifi capable devices (laptops, tablets). Because we could use the Internet for some time, while using the Xioami I mistakenly would keep the phone plugged into the charger so not to run down the smartphone battery. Then on one hot day, after using the phone as a hotspot with charger plugged in (and charger was very warm) the charger failed to charge the phone anymore, and at that time I was only able to charge the Xiaomi via my computer with the USB cable (which is much slower to charge). A few days went by and the charger still did not work.
So I decided to try a technique that worked with my old Asus TF101 transformer's charger.
I wrapped the Xiomi Mi 4c charger inside two layers of plastic bags, and placed the charger (thus wrapped) into a freezer overnight. I put it in the plastic bags to protect it against humidity. The next day I took the charger out of the freezer, took it out of the plastic bags, and let it sit for a few hours so any humidity would evaporate. I then tried the charger with the phone and it worked fine with the phone, charging at the same speed as I have observed in the past.
Since then, I have not kept the Xiomi Mi 4c charging with the charger at the same time as I used it as a wifi hot spot. Instead I plug the Xiaomi into my laptop computer to provide power when using the Xiaomi Mi 4c as a hotspot, and this works much better.
.
Does anyone know how to ask the charger to switch to 9V or 12V? Is this done via D+/D- lines, or with pullup/pulldown on new Charging Command pin?
Can't find an official specification anywhere...
EDIT: found it, page 9: http://industries.ul.com/wp-content/uploads/sites/2/2016/08/QuickCharge-2.0-Application_v12.pdf
Set D+ and D- to 0.6V for 12V
Set D+ to 3.3V and D- to 0.6V for 9V
can you unlock it?

The other night I put my note pro on the charger with around 28% battery. After 8+ hours charging it was only at like 90%. I have been noticing pretty much every time it charges. Is there something that I am missing? I am rooted, but don't mess around with much on this tablet simply because it doesn't need much tweaking. I am using an official Samsung USB 3.0 charger with a 3ft cable. So no non-standard overly long aftermarket cable or anything either.
I am thinking of doing a factory wipe on it, maybe that could help. Hope there isn't a physical issue with it because I could see Samsung denying me because of tripped Knox...
Thanks.
Whats your standby battery drain like? If you're seeing significant drain while not charging this might be an indication of something running in the background that's reducing your charge rate too. Is charging speed improved if the tablet is powered down?
As a point of reference using GSAM Battery Monitor I see a charge rate of about 1200ma at idle with screen brightness low. You may want to try a battery monitor app such as this, perhaps it will help pinpoint the issue.
Could be the charger itself . . .
You can also go Settings - General - Bttery and tap that grey bar (where reads how long you have been running since last charge)
Then check Awake.. If there is blue bar even when your device has been longer time without any using, it tells that some app or something is not letting the device go to sleep --> which drains battery.
Have you tried your original USB cable? The stock cable is longer than 3ft

Did you charge on Power Saving mode? I think, that option slow down charging
Did you turn off all running settings? (WiFi, GPS, Sync). Did you Greenify all Apps?

Thanks for pointing me to this app. I installed and will take a look at what my tablet is doing. Seems like I have been getting much lower "Screen on" times lately too. I don't recall installing anything that would do something to drain.
As for the charger, I bought the tablet from Amazon as open box. It was supposed to come with a charger but didn't. They gave me a partial refund and I bought a charger on ebay with the same model number as the stock one but it only came with a 3ft cable. I wouldn't think having a shorter cable would make a difference...

I never turn off settings while charging. I don't feel that you should need to. I generally keep GPS off all the time anyway, I have a phone for Maps!
Thanks for the replies all! I will report back on what I find.
You likely have an application causing drain and GSAM should help you figure that out.
In addition I would suspect the charger; check the voltage and see if it's rated for 5.3V at 2.0 amps.

Keep in mind that turning off WiFi speeds up the charging by about 70%. And since we're talking about a device with 9500mAh...
It's fine that you feel one should not be required to do so. To each their own. Physics, however, has no interest in 'feelings' and what people think should happen. Turning off a service that uses a lot of power means it'll stop draining a large percentage of the feeded charge. Elementary physics. (Just like how a cup is filled faster if you stop drinking from it whilst filling it.)

The charger that I have is model number: EP-TA10JWS
The output is rated for 5.3V and 2.0A.
I suppose there is a potential that I got a bum charger, or its a very sophisticated knock off. But the labeling all looks very legit and identical to my wifes Note 10.1 2014 charger.

So last night I tested and I TURNED OFF my tablet completely to charge. I think I had about 18% left when I put it on the charger and when I woke up about 7 hours later and turned it back on, it was at 91%. Does this sound even remotely close?
I also tested last night plugging in my charger and turning everything on the tablet off, WiFi, screen brightness all the way down, closed all open apps etc... In GSAM Battery Monitor my input was only like +800 mA. @muzzy996 you have 1200mA??? Seems like the issue must be the charger in light of my testing...
Another thing I tested though was using my wife's Note 10.1 2014 charger this morning. I believe it has the same output (5.3V / 2.0A) but I used the USB 2.0 cable that is included with it. I was only at like 650mA when charging. I think I will have to track down another charger and see if it makes a difference...
Thanks again for all the replies.
I believe there is a defect in the charging software or hardware. I used several iPad 2 car chargers rated for at least 10 watts. (5.2Volts x 2Amps) They take 5x longer to charge than the iPad. Talk about proprietary hardware/software.
The OEM charger EP-TA10JBE is rated at 5.3Volts x 2Amps. The voltage loss in the 4Ft cable supplied must be at least .1 volts, so I do not understand that the voltage difference should cause the charging rate to slow to a trickle.
I'm going to try this.
I'm having the same problem and I read the following in another thread. I'll let you know if it works for me. My charging time is not quite as slow as yours, but it's still slower than it was when I first opened the box and I've only had it less than 2 weeks.
"had the same problem after updating to 4.4.2. It only charged when off. When the device was on, it mentioned 'not charging' in the battery status, but in fact it did charge very slowly when the device was not in use, about 5% per hour.
Also when used, the battery was draining more quickly than before the upgrade.
This solved it for me:
- reboot in recovery mode (hold volume up, button and power while booting)
- clear cache partition
- reboot.
Looks like something in the cache is causing the system to consume (almost) more power than is supplied by the adapter..."
Working better
After clearing the system cache, the charge speed went up to about 22% per hour with the tablet shut off. Seems to be huge improvement in my case. I used the cable that came in the box with tablet.
The standard note 12.2 charger: EP-TA10JWS, The output is rated for 5.3V and 2.0A.
My Galaxy Note Edge has fast charging and regular charging capability. 2 outputs; 9.0V - 1.67A or 5.0V - 2.0A
Has anyone tried this/a fast charger with the note 12.2 ? Will it work ?
Probably not as it doesn't have the fast charging capability, but worth asking the tech savvy people out there.
Besides for travelling purposes it would be great just to carry one charger instead of 2.

Correct it will not fast charge, it needs both the fast charging supporting device and charger to work.

Sorry yes, corrected.
Dont forget it has a 9500mAh battery. The Note 3 has 3200mAh and charges from 0 to 100 in 90 minutes. So you'll always be looking at at least 4-5 hours.
If you leave your connections(Wifi, gps, mobile data, etx), sync and apps running, don't complain that it takes ages to charge.
Fast Charge pre-S6 is Qualcomm tech. The new Exynos chips support their own Fast Charge, but that doesn't apply to the old Exynos devices.
The Snapdragon NotePro's have Qualcomm Fast charge. (Which is not the same as the one in the S6)
The Exynos devices do not. So the P900 will always be slower in charging than the P905.
If you have a p900 and it's slow to charge, that's why.

I tried mine with a 15V charger from my TF700T, and it didn't make any difference.
You can use the Note Edge charger, it also supplies normal levels for ordinary charging. I often use my Note 3 charger.

I don't know the output of your charger but the correct one should have 5.3 Volts, 2 Amps output. Using other chargers which has lower output such as 1 Amp will cause a longer time to charge.
In order to verify which one is at fault, everyone should have this tool, no more guessing when you can see the voltage and charging current .

You should swap one by one, using a known working charger and cable to verify which one is the source of problem. Start in order: charger, USB cable, USB port until problem solved.
If the reading is not 5.3 V, 1.7A, something is wrong with your charger, USB cable. or USB charging port ( new one is only around $12 ). When near full charged, current should be under 1 Amp.

The Note 3, TabPro and NotePro chargers are identical. They have literally the same EAN and product code. The only thing that varies is the cable.
I don't have any 1A chargers anymore, they're useless to me these days. Even all my car chargers are 2.1A.
I've spent a solid half hour searching every place I can think of, but haven't come up with anything. Has anyone managed to find a third-party replacement charger that will activate rocket charging (double lightning bolts), or found a place that sells OEM replacement chargers (especially in/to the UK)?
In India, its available only at the service centres for Rs. 1600 (GBP 19).
Thanks. Lenovo or Motorola service centres?
Any news of any third-party chargers that actually work with rocket?

Thanks, but I literally just got a refund for a very similar product on ebay about 10 minutes ago. Sellers list the same item, which is a general "adaptive quick charger," for dozens of phones and don't bother to find out if they will work.
It seems that Lenovo's is somewhat proprietary and any old adaptive fast charger won't work.
Hi
I can confirm this car charger works in fast charging mode for the P2 and S7 Edge, it a multi standard charger
The P2 uses MTK Pump express so you need to look for a charger that supports this.
https://www.aliexpress.com/item/IBD...-Mobile-Phone-Travel-Adapter/32812410639.html
I can really recommend the IBD charger its really well built and works with other phones as well so future proofed as well
I live in the UK and it took about 9 days for delivery from the seller above
Thanks! This is really helpful, much appreciated.
It looks like the following Sony phones also support MTK Pump Express charging: (as per http://bit.ly/2vH9wfl)
-Xperia™ XA/XA Dual SIM
-Xperia™ XA Ultra/XA Ultra Dual SIM
-Xperia™ XA1
-Xperia™ XA1 Ultra
I've gone ahead and ordered a charger from this link: http://www.ebay.co.uk/itm/162631584402 , which specifically mentions the MTK compatibility. I'll check back in and let everyone know if it works.
The info in this thread sounds wrong. The Lenovo P2 doesn't use mediatek chipset, so it shouldn't have MTK Pump Express charging. However, I've charged my P2 using 2 different Quick charge 2.0 chargers and they work with the double lightning bolts.
Since the chipset is a qualcomm snapdragon, I would've thought only QuickCharge 2.0 (or 3.0) chargers would work. But @imi2003 has experience to the contrary so I won't fight him on that.

Just editing this post coz I've actually clicked through to your link. I don't know why you say that's an MTK Pump Express Charger. It's clearly a Quick Charge 3.0 charger as it states in the title and multiple times in the description. This should further confirm that any Quick Charge 2.0 or 3.0 charger can charge the Lenovo P2 fast and with double lightning bolts.
@ericastill Just buy any charger on amazon UK that claims to have Quick Charge 2.0 or 3.0.

My QC 2.0 charger (which worked fine on an S7 edge and G5 plus) won't quick charge my P2. It's not impossible that there's something wrong with my phone, though everything else is working fine.
In any case the sony charger I ordered supports both Pump Express and QC 3.0, so maybe that will do it.
Hi all
Just to clarify the car charger I linked to in my previous post, supports the following charging modes
QC 2.0 ,QC 3.0, MTK PE2.0, Huawei FCP/SCP
I got the charging specs from a different forum which I have linked below.
ht t ps : / /w3bsit3-dns.com/forum/index.php?showtopic=761560&st=7760
I hope this goes some way to end the confusion around charger compatibility. It might be a idea to make a sticky somewhere with proper specs.
If the P2 was QC 3.0 then the P2 wall charger would fast charge my S7 Edge, which it doesn't.
Better invest on powerbank...

*Edited* to sayThe Sony XA1 charger I bought now only charges for about a minute and then switches off (though it works fine charging other items such as my kindle). The hunt continues!
The P2 charger has a capacity of 25W. So find a charger of that same capacity and you can get the fast charging in Lenovo P2.

Do not give wrong advices to the people. You have no idea what are you writing about.
Quick charge is not only about output power of the supply but also possible output tension. In case of Lenovo Quick charger these are: 5.2V, 7V, 9V and 12V
---------- Post added at 05:14 PM ---------- Previous post was at 05:05 PM ----------

"Charging is fast, too. You can go from empty to full in around 1hr 30mins using the bundled Rapid Charger. Rapid Charge is Lenovo’s own 24W fast-charging tech, and you’ll only get it from the supplied adapter."
http://www.gsmarena.com/lenovo_p2-review-1557p3.php
"We initially thought that the Rapid charging tech used by Lenovo must be Quick Charge 3.0 since the P2 uses a Qualcomm chipset. However, our third-party QC3.0 charger didn't charge the P2 particularly fast, so the jury is still out on whether Lenovo is using a proprietary charging technology. "
In short: only original Lenovo charger is good for our phones
Lenovo P2 can NOT be fast charged with qualcomm quick charge 3.0

I have 2 Anker Qualcomm Quick Charge 3.0 wall chargers one with single port and one with multiple ports. I have tried my lenovo p2 with both of them (in QC 3.0 ports) and it does not do any rapid charging.
I don't see any double bolt or double charging sign even when I have switched on power saving mode with the physical power save button on the side.
My Lenovo P2 model is p2a42 and I am on the lastest nougat software update that is P2a42_S244_170725_ROW.
When I go to detailed battery menu in settings during charging it just says "Charging on AC" i.e. I do not see anything like rapid or fast charging or anything like that.
I also installed the Ampere app on nougat I never saw the voltage going above 5v (actually always stay slightly lower than 5v) in that app. Unfortunately, amps calculation is not working in that app I don't know why. I do not know if it is QC 3.0 instead of QC 2.0 that is making this difference.
Also my phone was at 4% charged when I did this test.

would you mind sharing with us the model of the 2 chargers that could fast charge the P2? any link to buy them would be great too.
I heard that Infinix cq24ax charger support double lightning. It got the same spec with original p2 charger
who ever tried it ?
Just bought an 12v 2a charger from online shop in Vetnam. Rocket charge working fine. I think you can buy any charger from lenovo with 5v 7v 9v 12v 2a, it should work for p2
Did anyone find a charger? Can you please share a link?
I have the Samsung Note 4. Like the OP6, it has a proprietary "quick charge" mode, but I find it will also charge quite fast when provided with a non-Quick Charge source such as a battery that can source several amps of current.
How fast does the OP6 charge without the Dash charger and cable? (in terms of amps drawn from source?)
Like it would take years like why would you want to know this, if you broke your charger buy another and look after it like. It's one of the main features of the phone and they don't talk about how fast it charges like
At work i use a QC3.0 charger for my OP6. Didn't notice a great difference to the DASH charger at home. Maybe DASH is a few minutes faster.
40% to 70% charge with QC3.0 is still insanely fast.
Stay on topic guys. OP asked a question, which could be answered with facts, rather than opinions and scenarios. In my regular car charger, I go from 22 to about 70 in 40 minutes, if I can recall correctly.

I'm not sure if you're serious or sarcastic, but In case of the former, here are a few reasons why someone might be interested in charging with other than the Dash Charger:
1) AFAIK, Dash is available in AC mains or 12V Car charger versions. I often use a 20K mAH Anker powerbank battery for charging. That is usually in situations where other power is not available, but a quick charge is needed. Huge current is available, but would the OP6 use it?
2) I use a compact travel charger that has 5 USB charging ports. Using a Dash charger would require carrying another charger (big, bulky, without retractable prongs), and occupying one (or more due to the shape) additional AC outlets.
3) I have a phone charger in my bedroom, at my desk, in my travel bag (both AC and Car style), and in my car. A quick check on Amazon seems to indicate that the Oneplus6 charger is several times more expensive than other "quick charge" chargers. Over multiple charger locations, the extra costs add up.
Using the word "like" so many times makes it difficult to understand the post.

I'm Irish, apology
I have a stockpile of fast chargers that used the weird Nexus standard (5V, 3A, non QC) and they're okay, and for overnight or at my desk at work that's plenty fast to get the job done. The phone shows them as "charging" and not "charging slowly."
I purchased a "Tinduqin oneplus5T charger" from Amazon that works and looks exactly the same as the original dash charger for about $20, but it seems to already be sold out.
If you don't use dash charger,you only can charge at 5v 1.5a,I have tested it with apple 45w pd charger,xiaomi qc3.0 and nexus 5v3a charger

It won't charge very fast because it doesn't use any on board quick charge it's all in the dash charging brick
I have a bunch quick chargers 3.0 at home. It takes a life time. I end up buying the dash charger. I still use the quick charger for over night charging
there must be some sort of software restrictions on oneplus6 since measures show that oneplus6 cannot be charged with more than 5V-1.5A.

Do you own the OP6? Do you have a USB power meter that could measure the charging current with and without the Dash charger and reply with the values?
On my Note 4, it charges at about 1.17A / 5 V when the screen is on, and the current goes up to 1.6A with the screen off. That is with either a QC2 Quick Charger or a battery power pack. The phone reports "quick charger connected" in both cases.
oneplus6 has 85% battery left, measured with usb voltmeter and original oneplus dash charger 5V-4A, it shows that oneplus6 is dawning 5V-1.3A and same thing is happening with other usb chargers capable to deliver over 5V-2A.
I guess oneplus6 should be discharged less than 50% or something in order to start receiving over 5V-3A

Is it possible to use a the original DASH-adapter but with another USB-C cable? I need a longer cable so I can use the phone whilwe charging.
OnePlus has a original cable for sale which is only 150cm Long.
My question is if I can buy any other manufacturers cable whish also support some sort of fast charging. I've heard for example that DASH-charging is the same charging model that Huawei P20 Pro uses, they just have different name. .
So, is there anyone here that has switched the OP original cable and charge it up with a cable from another manufacturer?
There has to be a solution to this. Me myself can't. be the only one that needs s longer cable.

That's normal. Phones pull the most amps when on low battery, then progressively less as they are charged.
Check how much it pulls on <40% and <80% respectively.
Well, I charged my Op6 with a no-name USB 3.0 charger yesterday (forgot my dash charger at home, I was by a friend) and from 3% to 100% it took about ~1 hour and 55 minutes.
Not that bad I guess. But I still prefer my dash charger
I'm using a huawei p20 pro charger atm. Phone states from 75 - 100 it will take 33 minutes. (prob a bit faster if I don't use the phone.
Here is a charging session with a Oneplus 2 charger without quick charge
Charging from 27% to 100% in 2 hrs, 40 min - avg. Charging speed: about 1000 mA/h
Hello,
I'm using this old thread since we're talking about the same thing.
Is there a kernel or rom for the OP6 that enables to draw as much current as possible form third party chargers? It's sad that it's stuck at 1.5A no matter the charger unless you use dash charger. 2A is already something, 3A would be awesome.
Of course only if this a software limit.
Was searching about chargers that should work with the phone a little while back and there was allot of mixed and confusing talks about what charger to get ( most tests where done with Amper app, that does not show s*it), allot of people where recommending the sonic charger as the only/best option for 27W charging.
Not being available in my region, got myself a Baseus 30w charger ( the one with USB + type-C PD port ) + a USB-C power reader.
Phone is on latest MIUI EU version 11 ( android 10)
Those are the findings:
The phone will charge Turbo using the USB port and go up to 30 W
The phone will charge also up to 30W using the type-C port, but the Turbo is not displayed.
p.s. ignore the total mA charged reading. At first my usb power reader had a bug or something. it was reading 0.01A at 9V, Started working fine after a replug. reading 3 - 3.5A at 9v
The first photo is using type-C
The second photo is using the USB port. It only shows 12W because was just plugged in. But will go to 9V 3A in a few seconds.
Wait so does this mean the 30w charger works?

Is that the Baseus 30W PD Quick Charger you bought?
Are you getting the full turbo charge using the Baseus USB Type C cable?
Or
Do you need to use the USB Type C cable that came with the phone?
Or
Purchase another compatible cable?
I know, questions, questions, questions..
Was contemplating buying OnePlus 7T or Realme X2 Pro, but reluctant after hearing about the display issues [red tint, green tint, uniformity fault] that are affecting them.. Previously had the OnePlus 6T McLaren but didn't have great mobile reception..
Think OxygenOS and MUIU better forks of Android.
Think am set on the Mi 9T Pro UK/Global edition, just waiting to see what Blacl Friday bring from EGlobal.
Would buy direct from Xiaomi if had 256GB version. But they doing what OnePlus doing and preventing purchase. Stinks, because you get 2 year warranty as opposed to 1 year if buy direct. [OnePlus & Xiaomi do this].
The charger works 22% to 96% in 52 minutes ( 22% to 77% in 30 minutes as seen in the picture above, had to leave so i did not let it reach 100%) it charged with 30W till 80%
It does not display turbo with usb-c to usb-c. but it charges with 30W, don't think the baseus cable has anything to do with it. was just the cheapest 3A rated cable i could find, the charged does not come with a cable
Also did not test other cable for USB to type-c. had the original xiaomi one in hand. but again. don't think it matters. any 3A cable should be good.
charger model is BS-EU905
UK 30W Charger for Mi 9T Pro
Am nearly all settled on decided to get the Mi 9t Pro but will hold fire till see what Black Friday discounts there are.
I can manage to get the 6GB/128GB with EU plug from CSMobiles for under £305 delivered. But would prefer the 8GB/256GB model.
If I do get, then will be purchasing the 'Baseus 30W PD Quick Charger UK Adapter' -

don't think the 256gb will ever be sold outside Asia. I'm fine with the 6/128 model

Will soon find out..
well . i stand corrected. it seems there is a global version with 8 ram and 256 storage when i got my phone there was none. It's a good phone. so enjoy

Hey can you tell me the exact timing.
I mean from 1% to 100% in how much time and also let me know how much does it charge in first 30mins and 1 hr mark. (please try to make it from 0 to 2% .
With my 27W sonic charger it takes
0-57% in 30mins and
0-93% in 60mins and
To full charge it takes 1Hr 18mins
All from 0 to 100
i usually don't let my phone go under 20%, ill post if ill try it from 0 to 100
I bought this one: Fast Charger 30W MacBook Pro Charger with Type-C Cable Power Supply Fire-Proof PD 4.0 for Samsung Phone, The New MacBook Air/iPad Pro/iPhone QC4.0 (30W +Cable) from amazon, and at that time I paid $9.99
Can't say the amount of Amps but it charged my phone from 50% to 90% in 30 minutes! The only problem I had was the provided usb-c cable charges my Mi9T only in one direction (weird)
here is more info using the USB normal port and the original xiaomi cable, phone display's turbo charging, the USB power meter shows 25W going in the phone ( a little slower than PD):
9% to 30% in 10 minutes
30 to 40% in 5 minutes ( charging rate is around 20W)
9% to 100% 1:19:32
will repeat the test again once my 5A cable comes, and also using type-c PD
A lot of things are made in China, doesn't mean they are all the same quality lol. Factories make stuff according to the specs given to them, if they were asked to make poor quality items, they will. If you give them the plans and contract them to make A grade stuff, they will too.

That's a bit slow as my 27W sonic charger charges from 1 to 100% in 1Hr 15mins.
Does it really make a large difference compared using a 27W charger?

I wonder why I am not getting the promised charging speed of 50w?
With the screen off I am getting 26.99w at most.
With the screen on I am getting around 12w.
I charged my fone at around 35%. I have a hunch the 50w will only kick in from 0% up to a certain percentage.
Anybody here observed similar results?
50 w is just for the beginning, when your battery is almost 0%.
The charger is not 50W flat. The charging power will change depending on the battery charge.

I understand your point
but if someone came from 30W charge phone to 50W charge phone
he will expect it to be faster at least, not slower
25W is very good but it is not 50W
I think he is asking to see is it SW bug or HW problem or just a big lie from Xiaomi about how much we should get in real world

Okay, i had both phones, a OP 8pro (30w charge) and my new Xiaomi 10Pro and compared charging speeds and the Mi10 Pro is much more faster than the OP8 pro, it felt it takes hours until the op8 pro reaches 100%. i dont care about measurements, ampere showed me a peak of ~9500ma at peak on the mi10 pro, no idea about the OP8pro on ampere. My Mi10 pro had a 60w charger but i dont have an usb tester anymore, if the phone got a 100% charge under a hour then everything should fine, isnt?
Maybe your USB tester isn't capable to detect the right power of the charger, as i know these usb testers are only able to count voltages from quick charge (1,2,3...)?? But i can wrong here...

Okay, i had both phones, a OP 8pro (30w charge) and my new Xiaomi 10Pro and compared charging speeds and the Mi10 Pro is much more faster than the OP8 pro, it felt it takes hours until the op8 pro reaches 100%. i dont care about measurements, ampere showed me a peak of ~9500ma at peak on the mi10 pro, no idea about the OP8pro on ampere.

he he, thats a funny thing, trust me ...
i bought the oneplus8 pro at relaese day as popup edition (cases and headphones included) 999€ and i used it for a bit more than one month BUT i never was satisfied at all, i mean there was a lot of camera improvements over time but i couldn't understand the hype about the display and when it comes to battery life i was a bit disappointed. (My former phone was a Huawei P30 pro) I had the feeling the battery was draining faster than normal and as i said, i never felt completely happy with the phone. So last weekend i surfed in the web and found a shop in the city next to me that sold the Xiaomi Mi10 pro so i decided to take a look on the phone. And trust me, i saw the phone in the store, played around a bit and i knew immediately thats the right one. I compared both phones a lot and until today i doesn't regret the decision. The Phone is Top notch in battery, display, performance i miss nothing from the opo8pro and i'm lucky that i sold the phone. All i kept from the oneplus was the WirelessZ Bullets.

I think he is asking to see is it SW bug or HW problem or just a big lie from Xiaomi about how much we should get in real world

My point exactly. Notice i never complained about the charging speed. My issue is Xiaomi advertising this to have 50w charging but we consumers are only getting 25w tops. I am trying to figure out why. Will try to charge with the ampere app.

mine charges with like 50w (45-50w) until about 40% and after that it slows down gradually, which is the expected behavior.
this phone changed the way I use my phone completely! I always charged my devices overnight to 100. but now considering how little it takes to charge this phone I just don't think about charging every time it gets to like 10 I plug it in to 80%.
1% to 80% took 33min, 3502mAh
4% to 80% took 29min, 3227mAh

Did you use a tester to conclude you are getting 45-50w below 40%? If so, may I see it? I am suspecting the low reading could be due to my tester.
True, the charging speed changes the way I use my phone.

yup I have some cheapo china testers
the better one (usb c) shows about 45w when charging
the second one (usb a) only allows quick charge 18w because the 65w xiaomi charger uses a half assed usb 3 port (one pin more than usb 2) and
therefore only works if the (usb a) tester also has usb 3 pins. For the same reason if you use a normal usb 2 (usb a to c) cable you won't get 50w
i also tested it again. it charges up to 33% with ~45w and then goes down to ~30w I checked again at arrount 65% it was charging with ~25w. At least these are the values that my tester shows
other values (charge % , time, mAh) in my previous post were readings from the phone itself.

My usb tester is exactly the first photo. Since I got my unit used, it might not have the original cable.
Would you be kind enough to check if on the USB A side, where the cable attaches to plug, does it day 3A?
Also, at what amps does it say when the charged is doing 45w?
Thank you

You can see the extra pin by looking down the port
I marked them in the attachments. Basically it's one of the 5 extra pins that usb 3 uses.
Sorry I have to check again later for the exact amperage, just charged my device. This time i checked the percentage and it charged to 41% with 45w. The deciding logic is probably more complicated than just a percentage.
Edit: added a photo with the exact charge info
the reason u r not getting 50w is bcos u put a meter between the charger and the cable... in order for xiaomi to draw out 50w from usba they put in a small microchip inside the cable to trigger the 50w quick change. if u look into the usb cable u will see extra pin in the middle of the cable, this pin work with the microchip to trigger the 50w quick charge.
solution:
1. always use original cable come with the mi10pro phone.
2. dont plug anything between the cable and charger.
3. if u want to test charging speed with meter, use type-c to type-c meter.
FYi, xiaomi 50w is using 10v 5a.
The phone heats up to 43 degrees during fast charging.
