Question regarding fast charging code or hardware? - Xiaomi Mi 11 Ultra

Hi gentlemen
I am quite sure others have had this thought/question cross their mind.
Is the fast charging on these xiaomi phones or any other phone that supports fast charging based on a code that detects what charger and voltage and then applies the charge or is it strictly hardware related? for example
I put my xiaomi 67w charger in my mi 11 ultra its starts charging and switches on fast charge.
I put another fast charger in my Xiaomi mi 11 ultra and no fast charge?
question is, is there a code in the software of the phone that detects a certain kind of frequency entering, which then it unlocks the fast charge rate or function that, a xiaomi charger gives that, that another fast charger might not be giving hence it charges on standard even thought it might be exactly 67w or similar?
if its code related, can this code be found and altered? so those with lets say with previous phones that had fast charge capability and have chargers laying around can be utilised?
food for thought.
Regards
Faux

It was written somewhere that mi 11 ultra fast charge only activates when it is on. Basically A Xiaomi software is doing trick. So, it can restrict to certain chargers when phone is on. Fast charging doesn't work when phone is off.

if that is the case, the surely the code can be edited to accept fast chargers from huwawei and one plus aswell as other makes if any?

No. Even cable matters for these chargers, like OnePlus. It would be unsafe, risky to mess with this.

Xiaomi power bank

Hello!
I bought 16000mah xiaomi power bank and I wonder is it compatible with my G4?
Xiaomi output is not same as LG charger, is it safe to use it?
Best regards!
Hi, I´ve been using it since i have my G4 and haven´t had any problems so far
i've been using the 10400 mah capacity since day 1 i received my G4,
and as far as i can tell, if you got the original (not the copied ones), the electrical current is stable, no funny heating at all, charges almost as fast as LG charger itself.
I purchased the power bank from Hongkong goldway store in aliexpress.
It supposed to be official store
It's fine, the rate of charge is determined and controlled by your phone. The only time you should be concerned is if the voltage is remarkably different, i.e. using a 12V charger.

Why didn't you buy the new xiaomi 20.000 instead.? That one has quickcharge 2.0 included
I also own the 16.000 Mi powerbank to charge my G4 on travelling it works fine too. Dont worry about the output unless the voltage is different. The output ampere dictate how fast the charging speed, less ampere means slower charging. More ampere means faster charging but also raise the battery temp during charging. But as long it support fast charging it shouldnt be problem.

Options for fast charging.

Hi
I have the P9000 on the way and I am looking forward to it arriving. One question I have is what are my options for a fast charger? I am in the UK so require a three pin plug and don't want to have to use an EU to UK adapter. Am I able to use one of the many fast chargers on Amazon that say they work for Qualcomm's Quick Charge but do not mention PE+?
Thanks
i use the supplied cable with a three pin usb to UK wall adapter that we all use with older phones.
never timed it but it charges within an hour or so, its much faster than any other device i have on the old charge system.
no need to buy the 2 pin fast charge device their trying to flog on their site.

I just thought some sort of higher amp charger would be needed to power the quick charging, but I shall wait until I have the phone then see where I can go from there.

Yeah I thought the same too. Good luck with phone, I think you'll be happy with it. For price its a bargain
DON'T buy the Elephone branded wireless pad though, mine is rubbish (for normal charging that is, as I know its not a fast charger) its connects / disconnects all the time. Yet my son has a cheap wireless pad he got of eBay and its rock solid, lesson learnt I guess
I live in the US and I just use an iPad 12v charger. Takes around 45-60 mins to fully charge from 10%.
I use the one that came with my Google Pixel C

Anything with enough amps works, i.e. any of the tablet chargers >2.1A.
I have a five port charging bay that delivers 2.4A and it charges my P9000 just as fast as my "Quick" charger. Now I'm annoyed i gave out the 20€ extra...

Yes, agreed, my phone charges quickly, whether using the fast or a standard charger!
I'm using a Lumsing 4-port charger (the "old" model without QC 2.0; 2.1A max per USB port) and it charges my phone really fast, I'd say about 60% in one hour. So I dismissed my plans about buying the official quick charger

what is the output amp rating on your charger?
I just bought an Aukey QC3.0 charger and it does like 80%/h
I bought a meizo PE+ charger and it does the job. Around a hour form 0 to 100%
Are these chargers that you use safe / fully compatible
I'm using tronsmart quick charged with volt IQ, is a very good option

How quick?
Everyone saying that the 'output amp rating' on 5V only output chargers is the way to determine if you're fast-charging your Elephone P9000 is unfortunately incorrect. A phone with PE+ uses load modulation to signal to a compatible charger that it should adjust its output VOLTAGE. There's a datasheet available somewhere that describes the protocol, but basically one set of current pulses (can be observed on an oscilloscope) means turn up the voltage, another set means turn down the voltage.
I managed to observe this behaviour, and simulate a compatible charger with a bench supply. When I saw the current pulses indicating a 'please increase voltage' signal, I wound up the volts on the supply from 5 to 12 volts, and the phone would draw up to 1A at 12V. If I left the supply at 5V, I would only see a maximum draw of around 1.7-1.8 A.
All this means is that compatible chargers are running at up to 12 Watts, whereas "high output current" chargers which only put out 5 V will only charge the phone at 9 Watts. Also, this is not compatible with quallcomm's quick charging system, which actually uses the USB data lines to request the increase in voltage.
Also, in general, cables are important. Phones will monitor their input voltage, and if they see it drop below some threshold, will reduce their charge current to match. If your charger doesn't have the current capacity to shove out to your phone, then the supply voltage will droop there and the phone will reduce the load. Similarly, if there is too much voltage drop down the cable (V=IR, R is the cable resistance, I is the current draw, V is the voltage drop) then the charging current will also be automatically reduced.
Also, strangely, my elephone p9000 recently stopped doing the PE+ thing! Now, there are no current pulses, and it only draws at 5V. *confused
I totally agree with the explanation of robot-army.
The Pump Express + charging technique is more than a simple current flow grossing.
This subject have been analyzed on another phone using the first mediatek Pump Express design used in the Zopo Speed 7:
http://forum.xda-developers.com/speed-7-plus/general/mediatek-pump-express-plus-zopo-7-t3336430
In that thread, you'll find the document that explain clearly the signal pattern awaited by Pump Express chargers to give their full potential. Without this management, they're just normal chargers and could be used in any other phone or device using USB standard to be supplied.
@robot-army: your problem regarding Pump Express management is known and it seems that since update 20160608, the kernel doesn't include this function anymore...
I saw that you shared your issue in the official Elephone forum on the following thread:
http://bbs.elephone.hk/forum.php?mod=viewthread&tid=11411&extra=page=1&mobile=2
I don't know if the kernel source used by Deepflex will let him put back this option ON in his CM13 Rom as it's an important feature of this phone and it seems that the Elephone Software checking team is not very serious about this point...
The lack of control of an highly advertised feature is a remarkable flaw, and even the last 20160715 update available doesn't correct this important point!
Please Elephone team, have some respect with your customer. The P9000 has a very good hardware basis, but you're making people changing their opinion because the software basis is not handled properly.

Mi5 and QC with original charger+cable - What values expected in apps like Ampere?

Hello everyone,
Ever since I got this Mi5 (125GB 4GB version) I've been trying everything I can so see it its behavior matches what is advertised. I should start off by saying so far so good.
Coming from a Moto X xt1092 I was used to some sort of indication that I was plugged to a QC enabled charger, not just a regular one. On this Mi5, however, and keep in mind that I'm under Lineage OS, I have no indication. I can count the minutes it takes to fill up a dead battery or maybe just 50% percent of it, but I'd like a sure and bullet proof indication. Also keep in mind that I'm using the original charger and cable - said charger that has the QC symbol on it.
Reading other threads, I noticed some posters were advised apps like Ampere - which I installed. Now, what kind of values should I expect from the app when charging? As of now, it hits a maximum of 1610 mA. What should I be looking at and what are the cutoffs above which I can be sure it's quick charging, as opposed to just regular charging?
Thank you in advance.
Added info: just set it to charge at 4%. 38 min later it was at 29%. It seems to me that 25% in 38 min is below QC 3 or even 2 standard (as it is often said that despite the mi5 being QC3 compatible, the original charger is QC2).
So, any chance one of you mi 5 owners can grab that app and give me some reference numbers? Just so I know for sure that I need to try and get a refund for the charger the phone shipped with.
4.1260 V
2860 mA
Edit
Miui 8.2 by xiaomi.eu
7.2.9 beta weekly

Thank you.
Yeah that's way higher higher​ than what I'm getting. Also, under technology I have "Li-ion", and a much lower Voltage.
Weird.
Something is definitely up.

the brick you get in the box is qc2. The device supports qc3 though and if the device is hot it will go upto 1610ma only buy a qc 3 brick roughly your charge should be done in 1hr 15-1hr 30 minutes
I knew the charger was qc2, I just thought it would go higher than 1610, which is exactly the top mA registered. Thanks for that info - I guess there's nothing wrong with it.
I have a qc3 charger on the way too.
The shipped charger has max current of 2.5A and indeed, during the first 10% ampere shows value near that (23XX mA on my phone). It will then gradually decrease down to 0.01A when the capacity is above 95%. Using real QC 3.0 charger (I have both Tronsmart and Aukey), the first 10% it can reach 28XX mA. The ending is similar, though.
I use the stock charger and cable that came in the box. I bought it here in macedonia. But i dont have an idea for wich market it is destined. I can confirm that it charges the phone to 85-90% in less than an hour, then it gets slow as stated above
Yeah I don't get those times, not even nearly. As you can see from the screen shot it took about two hours, most of which with screen off and no activity.
Do you have the same oem charger that i pictured above?
try to use different cable or different charger like aukey or tronsmart..
FYI original charger which support QC 3.0 Just MDY 08-EH

No only mainland china mi5 ships with QC 3 other regions where mi5 is sold only gets qc2 charger Google it if you want
Well mine was bought in Macedonia (south east europe) and i got a qc 3.0. indeed it is not with a local standard socket so i use a smalla dapter for the plug, but the point is that it depends to wich parts of the world xiaomi "officially" export, and to wich parts of the worlds (most of them) local companies undertake an adventure to import a batch of several hundred or thousands units from xiaomi, thus meaning destined for local chinese market

Yes, the exact same. But as that's not an European plug, I wonder if that's why I get different performance - it came with an adaptor.
I'm awaiting a new cable and charger in the mail soon that should clear it up.

It's stock charger bro.
Using the stock charger, a qc2.0 one (given with the international version of MI5), I get about 2200ma - 2300ma. I haven't tried a quick charger 3.0. However, check your kernel as well. The stock one of Lineage OS have an issue with quick charging, working once only after boot. I use DragonXia kernel and the qc works all the time.
To check if it is kernel issue, shutdown your phone and them connect the charger. I will start charging but using the recovery/boot kernel based on marshmallow, which (at least for me) hasn't got the issue of qc. Observe then the speed of charge and report.

Tested a mi5, same variant as mine, just today, with same lineage OS version. Also original charger and cable. Values are the same as yours, well above mine.
However, my original cable is defective, and has been refunded as the phone wasn't being recognized on the pc (which was a problem when flashing roms). A new one is in the mail, and in a day or two I suspect it'll solve the issue. I'll let you know.
Keep in mind apps are a bad way to check for QC capability.
My xiaomi stock charger puts out 1,8A @ 6V with 70% full battery(the higest current is being used between 20-50%, i'll try that later on)
Ampere only shows battery voltage(3,7-4,2V) instead of charging voltage and the ampere display is way off actual current

Mi Mix Factory Charger/Type C USB Question/Issue

Hey guys,
A few weeks ago I made a thread about my Mi Mix NOT detecting on any PC despite trying different Type C usb cords and the factory one.
I've never really timed how long it takes to charge my phone and recently I downloaded this Ampere app that measures the voltage and mah.
My Mix was at 40% and I plugged it in and left it in for 20 min and checked the app. It said something like 3.7 voltage and charging at 120mah minimum and 190mah maximum.
From what I'm reading, thats really bad.
So I plugged my phone in with an Anker Type C usb and a charging block from an LG 5.
Phone was now charging at 1600mah ish.
I'm assuming there is an issue with either my charging equipment AND / OR the charging port of my Mix. I've already ordered a new charging port from aliexpress 3+ weeks ago because of my PC unrecognized issue.
Anyway I just want to confirm that getting 120mah- 190mah on the stock charger is NOT normal?
I've ordered this https://www.amazon.ca/AUKEY-Charger-Samsung-Qualcomm-Certified/dp/B00RJO6AHM
and another Anker Type C cord to replace.

I don't have it with me, but I think the original Chinese charger that comes with the Mix is a 2.5A/5V one.
I've never used it, don't trust the Chinese chargers, rather have used an original Xiaomi EU approved (CE marked) charger that came with a Redmi Note 4.
That charger is "only" 2.0A/5V, so you don't get any "fast charging". But the Mix will still get fully charged in max 3 hours, which is fine for me.
And I figure the battery will last longer, it gets quite hot when charging at higher rates.
I know because I tested on a Mi Note 2 which came with a 3.0A EU approved charger. That charger works fine, really fast, and I trust it from a safety point of view - much heavier and thicker than the Chinese one.
But I charge the Note 2 with the 2.0A charger also, to spare the battery.
Normal charging current is 1500mA and up, depending on the chargers capacity. It will be less towards the end of the charging cycle, when the battery is nearly full, and sometimes also in the beginning, for some reason.
Don't understand why, never figured that out.

well it sounds like my factory charger is messed. 190ma when it should be getting at least 1000ma. I hope that the Aukey charger I ordered is safe for it, I've done some reading with other xiaomi phone owners and they've purchased it but I haven't seen a Mi mix owner review it. It says its CE approved.

Aukey has a good reputation, but I prefer the Xiaomi original EU approved chargers, just because they are "Xiaomi". (and I am located in the EU, of course.)
There "might" be some sort of intelligent interface built in that especially suits the Xiaomi phones.
No particular reason to believe so, just color me superstitious.

That can and does happen on certain custom ROMs and rapid charge doesn't kick in all the time. I can also say I had this issue on lg g5 and the charger proved to faulty on this occasion. So try the new port with old charger see how it goes. If no improvement try a different charger, the ones that come with the phone are very good. IMO

the new charger and cord are getting me fast charge now!
Bought a CHOETECH 50W 6-Port Desktop Charger last year and attached it to my bedside table; one of the best purchases I've ever made; quickcharge 3 on two ports and one power adapter in place of the 3 or 4 individual chargers I used to have. Bargain.

Doubt about fast charge

Hello friends. I've just bought a S20 FE Snapdragon to my wife but I have a doubt about fast charge.
My 18W Quick Charge 3.0 and my 27W Quick Charge 4.0 don't work as I wished. They just do a normal charge.
I've read that Exynos Edition uses Samsung 25W charger, but what about the Snapdragon edition? Does it use this 25W charger? What about the 45W charger?
Thank you guys.
yes it supports up to 25watt charging, you have to turn it on yourself if it's not activated.
battery and device care / battery / more battery settings / enable fast charge

nothing above 25watts will work any faster, the maximum current draw is 25watts if it works at all. not all fast chargers do work properly, that might explain your Xiaomi 2hrs plus.
the phone and the charger need to be able to communicate with each other / be running on the same standard.

True. I just bought a Samsung 25W super fast charge to my Snapdragon 865 and worked. I'll buy one for my father that uses an Exynos SoC too. It's sad to spend money with something like that.
I use the Samsung 20 w brick. When fast charging it get about 2%@minute.
Fast charging will not engage if the start temperature is too low or high.
If the battery has failed*.
Fast charging ramps down at around 80% to slow charging or if battery temperature goes to high. If temperature continues to climb above 102 F or so it will disengage entirely and end that charge cycle.
After 90% the charge rate crawls at as little as 1%@2 minutes.
* check for rear cover bulging. A battery can fail at any time but it's more likely to happen in an older degraded cell. Failures can happen fast, replaced asap, like that same day, if this happens. It can destroy the phone.
