Xiaomi Mi 4c Charging Analysis Part 1

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?

Quick charge or not?

Does this phone support quick charge? I ask because 2 coworkers got the Blu and let me play with it. Might be returning my Nexus 6 and grabbing one. Issue is I have the Anker 18W quick charger w/led. The led turns green whenever a phone that is quick charge compatible is plugged into it, and stays blue when a phone is charging at normal voltage. When I plug in my Nexus 6 or my Zenfone 2, or my wife's S6 the light turns green immediately, yet when I plug in the Pure XL it stays blue just like my older phones. So does this phone support quick charge really? I see in the specs it states it does.

The phone claims to have quick charge. I've been using it since last night and if it had quick charge it's a slow quick charge. Coming from the note 4 it's SIGNIFICANTLY slower for sure. It's border line a deal breaker for me. The battery life isn't as good so far and the quick charge is slower.

Im with you on the quick charge being slower. Coming from using the Nexus 6 for the past few weeks, I can argue that the battery life is slightly better than the Nexus, but the Nexus would charge lightning fast, kinda made the battery a non issue. Im gonna wait until the battery on my Nexus and the Blu are both at around 50%, then Ill plug the Nexus into a standard charger and the Blu into a quick charger and see if there is a difference.

But does blu support the quick charger of nexus 6 ? I think it is silly that now all the phones use same charging port but manufacturers make different quick charge protocols.
You can install a charge monitor app, for example "ampere" from market to see the charging speed. All that matters is the mA charge speed. Quick chargers will charge faster from 0% to 50%-85% because they can pump in power faster into the empty battery, but they have to slow down as the battery gets full or too warm.

I haven't gotten Ampere to show a normal drain value (0 mA is all it will display) and the charging values are all over the place (1.8A - 2.8A). I looked at various stories and MediaTek's specs on the MT6795 and there isn't anything about fast/quick charging. I think I charged about 40% (50% to 90%)in 20 minutes the second day I had it. It has a couple charge cycles on it now, though, so I will pay attention the next time the battery is low and see how fast it charges.

I will add that I have an Aukey QuickCharge 2.0 charger and it only shows a 1.4A charging rate but the Blu charger shows 2.8A so there is probably something MT specific going-on.

Quickcharge 2.0 charger is probably incompatible with MTK fast charge. 1.4A sounds like the normal charge current. But 2.0 - 2.8A sounds right for fast charging. Perhaps the values are correct, it may be fluctuating. If I remember correctly, I saw 2.2A in my nexus 6 when it was 75% charged. (I should also check it from empty but I usually just keep it in charge so charge never goes under 50%).

It does fast charge using the charger that came with the phone.... If you look at the charger specs it reads 5/9 volt 2.1 amps.... Probably has a small procceser in the charger the phone sends a signal to that switches it to 9 volt charge

My phone charges very fast with included charger. I also tried a no name Quick Charge adapter ... also charges fast, but first shows Over Voltage Warning

The rate of charge is much higher when the battery % is low.

Sent from my PURE XL using Tapatalk

My HTC One X9 chipset is Mediatek MT6795 Helio X10. At HTC India website, they say something like 'Fast charging (5V/1.5A)' which doesn't sound faster obviously and my phone takes 2 hours to charge. My Samsung Note 2 was still faster (5V/2A). Mediatek MT6795 supports Pump Express Plus charging. Do you think my HTC phone support faster charging (higher voltage charging)?

its been my expierence that using the included charger fast charges, but if i use a "quick charge" charger it slow charges... but if I use a generic 2.4A charger it charges fast... stock Samsung Note charger SUCKS on these phones

Golden Shovel for me, but I think there's no need to create another topic
I have the new Blu Vivo XI+, which came with a " fast charging 5v/2A charger", thing is my phone has the P60 processor, which supports Pump Express 4.0, thats 5v/5A, it's ridiculous that Blu is shipping a common charger with a processor capable of such fast charging, anyone knows if the technology must be enabled on the phone itself, or if I just buy a 5v/5a charger it will work?

Samsung Galaxy S7 Edge Charging Analysis

I visited tronsmart website and found an interesting article. You guys might need such useful information so I post it here. Please note that I have removed all of the products links in this post.
The Galaxy S7 Edge has been drawing lots of attention since its release on 2016 WMC this past February. It features a 5.5 inch AMOLED 2K display, powered by Android 6.0 OS and a built-in 3600 mAh Li battery. Now, the Galaxy S7 Edge is currently available on market, but we sourced one previously and have already spent several days of testing its charging capabilities to make this analysis for our readers.
The Samsung Galaxy S7 Edge is equipped with the latest Qualcomm Snapdragon 820 SoC, and it supports Qualcomm’s Quick Charge 2.0 technology. Tronsmart has tested the Galaxy S7 Edge charging with its original wall charger, with a OnePlus 2 original charger, and with Tronsmart’s latest WC1T, W2PTE wall charger and C2PTE charger.
The following is the charging result and analysis.

}
1) Samsung Galaxy S7 Edge original charger (with Quick Charge 2.0 technology)
Specification: INPUT AC100-240V
OUTPUT [email protected], [email protected]
Result: Total Charging time from battery level 0% to 100% is 1 hour and 34 mins with the original charger, check the table and chart below for details, minute by minute.
Chart 1
From the data, we can see in the first full hour, battery level has already reached 78%, the maximum charging voltage is 9.19V, and the current is 1.62A which is about 15W of maximum power. Then another 34 mins later, the battery level is fully charged. During the last 34 mins, charging voltage is around 9V, but current reduces from 1A to 0.5A approximately in the end. The whole charging process lines up with the basic principle of a standard phone charging system. Smartphone batteries are charged in two stages as we have discussed in the past. The first stage can be performed with a high amount of power and takes the battery up to around 80%. Then the second stage kicks in where the power is reduced as the battery is topped up to full. It is proven, once again, in the following charging tests.
2) OnePlus 2 Original Charger
Specification: INPUT: AC100-240V
OUTPT: [email protected]
Result: It takes 2 hours and 1 mins to charge the Galaxy S7 Edge from 0% to 100% with OnePlus 2’s original charger that ships with their latest phone model. Check the table and chart below for details, minute by minute.
Chart 2
From the table 2, it is clear to see in the first 1 hour and a half, nearly the same time as Galaxy S7 Edge original charger time, the battery level is juiced up to 83%, and another 31 mins to be 100%. Maximum charging power is 9.5W. Compared with the Galaxy S7 Edge original charger, we note that the OnePlus 2 charger takes 27 minutes longer than the Samsung OEM model charger.
3) Tronsmart WC1T wall charger (with Quick Charge 3.0, also backwards compatible with Quick Charge 2.0 devices)
Specification: INPUT AC100-240V
OUTPUT DC:[email protected], [email protected], [email protected]
Result: Total charging time is 1 hour and a 30 minutes, almost the exact same amount of time as the Galaxy S7 Edge original charger. Charging details are below in table 3 and chart 3.
Chart 3
With 1 hour of charging, the battery level reaches to 83%, a little faster than Galaxy S7 Edge original charger. Then in the second charging stage, it takes half an hour to be 100%. Maximum charging voltage is 9.32V, current 1.58A, with a maximum of around 14.7W of power. We can see in the first charging stage, the WC1T charges rapidly and then become slow and steady in the second stage.
4) Tronsmart W2PTE wall charger (USB-A port with VoltIQ, USB-C port with Quick Charge 3.0, also backwards compatible with Quick Charge 2.0 devices)
INPUT: AC100-240V
OUTPUT1 (USB-A port): [email protected](Max)
OUTPUT2 (Type-C port): [email protected], [email protected], [email protected]
Result: Total charging time is 1 hour and 32 mins, again about the exact same charging time as the Galaxy S7 Edge original charger and WC1T wall charger. Charging details are below in table 4 and chart 4
Chart 4
In the first full hour of charging, the battery is charged to a level of 81%, then another 32 mins to be full. As we see once again, almost the exact same charging situation as our Tronsmart WC1T wall charger.
Note: As the Samsung Galaxy S7 Edge comes with a Micro-USB charging port, we use the Tronsmart CC08 USB-C to Micro-USB cable as a connection to charge the S7 with the W2PTE’s USB-C port.
5) Tronsmart C2PTE Car Charger (USB-A port with VoltIQ, USB-C port with Quick Charge 3.0, also backwards compatible with Quick Charge 2.0 devices)
Specification: INPUT DC12-24V
OUTPUT1 (USB-A port): [email protected] (Max)
OUTPUT2 (USB-C port): [email protected], [email protected], [email protected]
Result: Total of 1 hour and 33 mins to be fully charged. Charging details are below in table 5 and chart 5
Table 5
Chart 5
In the first full hour, the battery level reaches 76%, a little bit slower than the speed of the previous Tronsmart WC1t and W2PTE wall chargers. Then another 33 mins for stage 2 and to be 100% full charged.
Final Conclusion: The Quick Charge 2.0 charging technology can save approximately half an hour or so compared with the standard 5V/2A chargers on the market. And the Qualcomm-approved third-party chargers can achieve nearly identical charging times as the original Galaxy S7 Edge wall charger. If you need a car charger or a multi-port wall charger with Quick Charge 2.0, you can safely choose those third-party quick chargers to get the job done.

I'd assume as the charging time are almost identical heat would be basically identical as well. P=IV so for the same period of time the heat output will be equal.

Totally agree with your opinion

very interesting and very detailed

will this charger work with my non edge S7? the amps seem to be higher than on the original fast charger supplied with it and I don't want to ruin my phone.

I suggest you to use the original chargers or the QC chargers which have Qualcomm approval.

Can you tell me what program you use to measure average charging amp? I am trying to find a program/app that lets me do that and so far I couldn't find anything. I love to use it to test my charging device. Thanks!

Try this app - Charge Monitor for in phone monitoring of all the different parameters of your charging method.

Bro how do u check the voltage ? I used gsam battery app and when i plug in charger that came with box original fast charger it shows 938ma and 3.8 V? is this enough for fast charge?

I bought a tronsmart cable for my s7 edge and I can say that it is a high quality cable and supports fast charge. It cost me almost 10 bucks for a pack of 3 and 6feet long.

This car charger support Huawei FCP
https://www.alibaba.com/product-detail/Compatible-with-HuaWei-FCP-IBD-universal_60481400296.html

I've been using this one for a month or two now. Works fine: https://www.aliexpress.com/item/ITI...32633009425.html?spm=2114.13010608.0.0.wVRln2

Can anyone confirm that quick charge really works? I mean there is a quick charge notification in the lock screen and the two thunderbolts instead of simple charging and one thunderbolt?
@tap007 @perzan07 @evilpaul13
As long as I know most of the market chargers support Qualcomm Quick Charge in any of its three versions. QC 3.0 has backward-compatible with QC 2.0 and QC 1.0 devices so buying a QC 3.0 is the simplest answer for a devices that use a Qualcomm processor but Honor 8 uses a HiSilicon Kirin 950.
QC 1.0 is 5V and 2.0A and QC 2.0 and 3.0 are 5/9/12V 3A. The chargers have a driver based in Intelligent Negotiation for Optimum Voltage (INOV) to know how to charge the phone. I've read somewhere that Huawei QuickCharger has it own charging protocol and can charge QC 2.0 devices but a QC 2.0 charger cannot charge a Huawei (not Qualcomm) device.
So what I expect from all of those quick chargers in the market is that NOT recognise the Honor 8 as a compatible device and give it less than 5V 2A (10W), probably 5V 1A (5W) that are not the 9V 2A (18W) expected.
That's why I ask for a confirmation that charger and device recognise themselves and quick charge is really activated.
PS: In their webpage, Aukey says the following: "AUKEY AiPower Adaptive Charging Technology gives all your USB powered devices exactly what they need with up to 2.4A per Ai USB Port." and "Combine AUKEY AiPower with Qualcomm Quick Charge in a single USB port and you get PowerAll Adaptive Charging for all USB powered devices. One USB charging port to rule them all!" so maybe their chargers are compatible but I still looking for a confirmation somewhere. (I don't trust too much Alibaba, aliexpress, eBay... product descriptions).
Thanks!

I've gotten two chargers off there and both, including the car one I linked, support Huawei's Fast Charge. I get the Fast Charge message, my battery icon turns green AIDA64 says I'm charging at >1A. My battery has been lasting long enough I haven't bothered charging it in the car much though.

for the time being available only in china but maybe it will come also to other countries: HUAWEI SuperCharge CAR charger http://www.vmall.com/product/944393591.html

Based on this I ordered the itian charger linked above, it does NOT work for fast charging with the honor 8, no worries I'm not upset about it I just think people should know that this charger DOES NOT WORK for fast charging with the honor 8, I'm still looking for a car charger that will

I was unable to order them so I ordered an Aukey one with AiPower that I think could work. If does I'll post it here. If not I'll resell it to someone with a QC device. Thanks for the advice!

Well I've received the Aukey charger and I've to say that the info I read on some forums is wrong and it is not compatible with our device (and probably not compatible with any not Qualcomm Huawei/Honor device). The item bought was that:
http://www.ebay.es/itm/252404366500?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT
It official info here:
https://www.aukey.com/products/dual...ick-charge-2-0-aipower-with-usb-a-to-c-cable/
Review:
It came with 2 high quality USB cables, one microUSB and one USB-C. It looks as a high end product and works fine as a regular charger. May be your car charger if you are the owner of a Qualcomm Quick Charge 2.0 compatible device. About the seller just say it took 4 weeks to be in my place (one week less than average China packages).
Check pics attached. Regards.

I have the Elephone "Tornado" charger on order from the 'Bay, and supposedly it supports HFCP AND comes with dual charging ports.

I have this one for the car. I never see "fast charging" when using either port, but it does charge faster than a standard "cheap" car charger.

Any updates on the charger ?

Huawei does not support FAST CHARGING, it has its own unique charging which is Super Fast Charging, if you bought a car charger or any charger and use it and it did not show Super Fast charging Notification or your battery icon on the upper right has no 2 electric logo inside the battery icon it means you bought the wrong charger.

Hi
You have to look for Huawei AP32 it's Original Huawei wall charger
and Huawei AP38 it's Genuine Huawei Car charger.

Just to add more info regarding the ''fast charging''
I have orderd from ebay some cheap usb type C cable
And it works fine and gives the ''fast charge'' messege and I have
tested it ... it also takes same time in minutes to charge the phone..
So that means it has no difference to use that usb cable..
Some of my phones as soon as I changed the usb cable were not fast charging
That why I am reporting it ..

To anyone interested, I searched Nillkin's site for Honor 8 accessories and it gave a result for a car charger, called Nillkin Celerity Car Charger. It does support 9V/2A so I believe it should work with Honor 8.
I also found it in eBay cheaper than in Nillkin's site.
Also, Huawei Honor AP31 car charger should the job. It does support quick charge. Found it in eBay for about 25 US$.
P.S. Sorry but I cannot post links, since this is my first post.

How to charge with PD 27W?

On xda site they said the OP8T can charge up to 27W with a PD charger however I tried many PD chargers with all kind of cables combination and it never goes above 1-5W.
I'm not the only one, there are many posts on reddit about this.
What's your experience on this?

Same over here, can't get it over 5w.
Charging voltage has something to do with it, what's ur charging voltage?

Using a digital usb meter I noticed all PD chargers stay a 9V with 0.45A output. I tried a kernel on XDA that it's supposed to force fast charging but i didn't do anything.

I find it very weird nobody is talking about this on XDA, only a few threads on reddit.
If you are outside and you don't have your stock OP 65W charger with you you have a high possibility of not being able to charge at all since it can take 5 hours to a day a this speed. How is this even legal?

I may be a little confused here, but I get pretty dang close to 27W of charging power when using my USB C charging brick that came with my Samsung Galaxy Book 360. Franco kernel manager usually says I average around 25W charging power. I'm assuming the USB brick is USB-C with PD.

HI,
First of all (I'm using a usb tester) I noticed the cable has nothing to do with this problem. I have one BaseUS 100W PD charger, one UGreen 36W PD charger, one BaseUS 65W power bank and one 18W power bank. They are all able to provider PD charging at 12/20V at their maximum advertise wattage with my devices and a usb-c laptop. They can also provide 9V/3A (tested).
I noticed then when the battery is below 60% connected with a usb-c cable they all default to 9V/0.45A and sometimes even 0.22A (last night I left it to charge and in 8h it only charged 7%!) when above that you can get 5V/2.5A which is much better.
So I'm not sure what exactly those PD chargers are missing if they work with all other devices.
Also I find it weird you can see 25W from franco kernel since the phone shows half of the wattage being a dual battery. So yhat would be a real 50W.

Connected to a 100W PD charger at 1W

Latest OOS?

Yes of course.

Bro, something is wrong.... I just tested my google chromecast with google tv power block and cable and I am getting this:

I'm sorry what is the link of this charger?

I don't know exactly, whatever google uses for this: https://store.google.com/us/product/chromecast_google_tv?hl=en-US

It's a 5V 1.5A so that value you see in FKM cannot be real.
You should use BatteryGuru and multiply by 2.

Well I guess this block is different. It says 5V 3A or 9V 2A, so 18W would make sense no? I'll try a different app. This is from the battery guru app and electron app:

Yes makes sense now. I'll try to find other chargers at this point. I know everything I have is not supported by this phone.

It's like u can't find a compatible charger lol whatever charger I tried charges at 9v 1.8a until the phone reaches 65% and then it drops to 4.5v 0.4a and it takes ages to get from 65% to 100%
Idk what the hell is this problem but I know for sure it's their dual battery design messed up for real

Could anyone try monitoring charging voltage and amperage across different charging percentages and report back.
And for monitoring use OnePlus toolkit it's baked in the rom, *#800# to access it then tap on enter and tap on tools to see charger option and then choose it.
It displays the voltage and current without having to multiply it.

There was a thread at OP forums about this issue.

I suppose the problem is also in the technology itself:
In contrast to USB Power Delivery and Qualcomm Quick Charge technology, which increases the voltage during fast charging, VOOC/Warp Charge/Dart Charge use a higher current than standard USB charging.
All versions of VOOC require a proprietary cable to work. In addition to electrical requirements like thickness (low electrical resistance) to handle the high currents without overheating, the VOOC 2.0/Dash protocol requires a fifth pin on the (USB-A to USB-C) cable to communicate through. Without such communication, the charger runs at a limit of 5 V/1.5 A. From VOOC 4.0 this limit elevated to 5V/2.0A.
On the Android phone end, the VOOC communication code is open source under GNU General Public License (GNU GPL) version 2 as a part of the modified Linux kernel, and has been used by custom ROMs like Lineage OS.
So i presume it's just not compatible with many PD chargers.

Oppo Gan Charger Kit supports 65W charging protocol，You can buy it about 80-90RMB on the Xianyu app 。There is also a power bank that supports 65W charging called Sdoutech but a little expensive , 400RMB/26800mah about four times for 8T

Mainly I want to charge with other chargers and power banks I already have not buying other VOOC chargers.

I don't understand why it can't be compatible with many PD chargers if PD is a standard. What would be the discrimination factor here?
I tried charging the Pixel 6 that supports PD with every PD charger I have and they all deliver 23W, while on the OP8T all stuck on 5W or even less sometimes.
