Fast charging. - Xiaomi Redmi Note 3 Questions & Answers

Hey there users, I would like to know does our redmi note 3 support fast charging.

not by default, you can flash custom kernels to enable fast charging

I'm using mi power bank 2 10000ma .it charges at 2000mA

Hey there, I'm currently using redmi note 3 with resurrection remix on it. So far it's awesome but during charging it takes too much time. I have tried few kernels on my device like radon kernel and unfortunately I had some issues like lagging performance and all and since then not a big fan of custom kernel. Even then I'll try if you say so I may have done something wrong during the installation process. Anyways thanks man for sharing your views thank you very much I apprecitiate you efforts thanks a lot

Custom kernels may support USB fast charge ie they charge your phone at 900mA when connected to a USB 3.0 port. Remember this is not Qualcomm's quick charge which charges your phone at 5V, 9V, 12V which is not possible on Redmi note 3 since it lacks the hardware requirements.

Qualcomm fast charger

Someone use qualcomm fast charger? Is it work on G3?
it works but does not uses qualcomms quickcharge 2.0 but it does charges my g3 a little bit faster than my stock charger.i am using aukeys quick charger.
^same here, aukey 1 port quickcharge 2
the Lg G3 is a funny case, the Snapdragon 801 supports QC 2.0, meaning it can charge at 7 and 9v.
BUT... Lg disabled the native SoC charge/battery controller and used a external Texas instruments one which removes QC 2.0 capability.
I mresured it and more or less the Lg G3 charges at 1400mA at 5v even when using a Aukey QC 2.0 charger.
That really piss me off so much when changing from note 3 to g3. Note 3 even charge 2-3 times quicker than g3.
When i plug in the charger on my note 3, and still using it while charging, took me around 60-90 mins to get full.
But with my g3, took me around 180-260 mins to get full when using it at same time.
Cant understand at all, so freaking slow =.=
I thought those quick charge can fckup your battery ?
Im using a Quickcharger from Anker with a USB from Anker too and its sooo much faster like the stock. Cant say if its fast as possible, but under normal usage while loading it takes me 40-50mins. Without using 20mins i think.

I use the real QC fast charge 2.0 and it does work. You have to enable it on the kernel level to fully utilize it. I am using a custom AOSP ROM with the the Nebula Kernel, and Kernel Adiutor to enable the fast charging.
A word of warning, however: Do not leave it on the charger after it's charged and do not use the phone while its fast charging, it will overheat the battery and possibly ruin it, or shut off the phone, or both.
Guys, what if I use Galaxy S6 quick charger to recharge my G3? It will work?
here on stock rom v30c using some Samsung 5v 2A charger from 7% to 100% in 80-90 minutes. fast enough for me

dash charging in op2....!! Issues and things to be known and tested!!

Let me come to the point....!!
The oneplus 2 doesn't support the fast charging...
The reasons are:
1. Software update was not provided for it.
2. Hardware isn't capable for providing the fast charge
Things to be known:
1. The hardware support must be done with the CHARGER and the DATA CABLE not with mobile
2. The charger provides only 5v/2a output that is not sufficient for fast charging...
3. The DATA CABLE which Is provided by oneplus is USB 2.0 to type-c cable and its maximum data speed and power delivery is low compared to USB 3.0
4. Oneplus data cable uses the TYPE-C protocol 1.0 and data transfer speed will be slow compared to other cables
Things to be tested:
1. To try with other fast charger with other type-c cables other than oneplus cable
2. Kernel must be edited...
3. Use 3 party certified data cables which is USB 3.0 or 3.1 to TYPE-C cable for charging and data transfers as it boosts over 10gbps speed.
Conclusion:
Hence I request the developers and the people viewing this post to try out some test if they can.....!! I've posted this after researching over the net.. ain't posting for name sack
If you already ready know there hardware isn't there, then why bother testing

The Hardware problem is in the charger not in the mobile....!!! This is a developers site and people love testing and developing.... if you ain't interested just stay away

Apparently you have done an extensive research on the subject, can you post your sources? I mean the link from where your read all about?
Have you done yourself any of the suggested solutions?
I'm no developer but kernel solution might seem adding the correct charging driver... but driver and hardware must match then you must change the charging circuit for some with quick/dash charging.

Fast charge capable or not, I use my wife's Nexus 6p charger(cord and brick) and it's way faster than with the oneplus supplied charger.
So i used the OP3 charger on my OP2 and it seems to charge faster. Maybe is just psychological. So did some tests
Used Gsam battery monitor to see the charge current
Normal Samsung charger rated at 1.5A : current is 999 mA
OP3 charger : 1500mA
So the OP3 added about 5% in about 15 min
Worth trying. People have been discovering so many things on other phones which manufacturer claims not provided blablabla (could be for marketing stunts etc and preserve for next gen device) but was enabled through hacks by the community.
If there's time and interest, proceed in the name of science

That just mean op3 charger can deliver the max current for our device while Samsung's dont

I guess so, also means that there are better chargers than the stock OP2 charger available
I get between 1800 and 2100ma ma/hr from the stock cable and charging brick. This is measured with the 3c "battery monitor widget" as well as with a USB multimeter.
If I change the cable to an aftermarket one the charging I can get up to 1800ma/hr.
The charging brick makes little difference as long as it can push over 2 amps.
The phone seems to pull the highest amperage when it starts charging from less than 40% and is less than 30°C.
Hastily spouted for your befuddlement

Well that puts the dash charging theory to rest. But nice to know that the first 30% happens at almost 1% charge per min

Quick Charging

I just wonder if a samsung charger can increase the speed of charging. I am on NITROGEN OS stock kernel.
I have the original charger, a samsung charger and an apple ipad charger.
Should i charge it with the apple one for faster charging? Or samsung ?
Try both. Use the one that charges it the quickest
Doesent make a diff, try radon or agni kernal for fast charging!

If you are using kenzo, although the chip supports fast charging, Xiaomi hasn't integrated the extra chips required for fast charging since its a budget phone but anyways u can use custom kernels like radon or agni to boost the charge time!! *USE THE KERNEL AT YOUR OWN RISK, I AM NOT RESPONSIBLE FOR ANY HARM*
Like if I helped u, I'll appreciate that!
It's foolish to do so, you will end up harming battery due to heating
My battery always change very often when its charging from rapid charge to slow charge. Ane help?

Phone is charging with 500ma max.

hey guys .. before I tell you about my problem I want to apologize for my bad english
my problem is that my phone is charging with just 500ma max. .. I took that information from the app "ampere"
I bought a new cable and everything was alright for 1-2 weeks .. then I bought a very expensive cable from ebay for 10 Euros
same thing but this time it only worked for 3 days .. does anyone got the same problem with this phone?
the le max 2 is very hot while charging,could this be the answer to all the broken cables I got?
I thought about buying a USB Type C to Micro USB Adapter but how fast would it charge?

I charge with original charger . I use original cable as well as some other from Aliexpress. I measure the charging parameters with external USB tool. I have never had problems with charging. Maybe I'm so lucky. I'm also using qc 3.0 powerbank.
Currently I'm using Tiegem 3.1 USB type C cable which is 2m long.
Well, charging speed actually takes into concideration several things: ROM is the first and main thing, outside temperature and CPU temperature as well as thermal drivers matter really much.
If on EUI, the best thing you can get actually with stock rom is QC2.0 speed (Small EUI has enabled QC3.0 but thermal drivers lower than moderate will not absolutely ever charge the phone over 10W due to heating).
If on Nougat ROMs then the first thing to look at is whether the kernel limits charging speed (Blackscreen and Omni kernel most widely used on these roms use QC3.0 and will charge the phone at 18W up until the CPU thermals detect too high temperature).
TL, DR: Check your ROM and thermal driver settings. (Also charge in a cold spot rather than hot).

There is no different between charging speed of QC3 and QC2. QC2 definitely can go beyond 10W

Slow Charging and charging stops

Hello,
I have a 2gb version kenzo, i have used many roms and at the moment the best i can find for my device is the XIAOMI.eu MIUI 9. It doesn't crash all the time, specially on apps like snapchat, but there is a problem. It charges very very slow, like 400~ma at maximum, and it just stops charging after a while, and i have to unplug and plug the charger again. The battery doesnt get hot. I am using an official qualcomm quickcharger 3.0 with a good quality cable, and i can easily achieve 2500~ma acording to ampere while charging with roms like nitrogen os, lineage, RR, and with RADON 6.1 on this xiaomi.eu rom, but when i install Radon kernel my phone crashes a lot on some apps, and even scrolling through the menus. Is there any way to "fix" this with a flashable zip like with only the needed code, over the MIUI eu Rom to fix the charging issue?
Thanks in advance.

U should connect ur phone directly to transformer if u want 100amps. It will charge ur device very quickly.
Now lets get serious. U saying u r using QC3 charger. And u get 2500ma. Before using i advise u to read specs of kenzo.
The device is made to take max current 2A. Its QC 1.0 compatible. It can take upto 5V2A safely. If u think by using QC charger it can support higher current and take less time then u r wrong. It may take high current but it just converting it into lot of heat. Its not helping. And just deterioting ur battery.
Dont use tweaked custom kernels and select higher current option for charging. There is safety diode on charging board which is meant to take max 5v and 2A. QC chargers are made to run in variable voltage. So if ur charger drawing more than 5v then ur diode will blow and prevent further charging to protect ur device. Min charging time for kenzo is 2hr 10 min. It cant be shortened more than this even if u go for high power.
I suggest u to stick to default charger which operates in 5v2A. Kenzo dont support qc2or qc3 and dont have components to take high voltage current. Many people have used QC charger and ended up in service center and replaced charging board.

Thank you for all the information. I have been using this charger for quite a lot, and o noticed that my battery life isnt as good as it was, but i still get like 7h of SOT which is note than enough for me. I dont know where i have my original charger anymore, but i will try to use it. I stopped using it simply because it has chinese plug and its kinda bulky to carry with the adapter.
Best regards.

I had qc3.0 charger by tronsmart. I threw it in river. My safety diode of 2 charging boards blown in a week coz of qc charger. Phone heated like furnace and It stopped charging in a week. So i read somewhere in a xda thread how to restore it. Then i opened phone and scratched and removed the diode from the board with tiny screwdriver. since then I am charging with stock charger again coz diode removed and device need safe and constant voltage. No problem since a year.
I think Only Redmi note 5 pro have Qc2.0 enabled in redmi note series. To charge a device with QC mechanism phone should have a set of charging components and cpu should support it. Our device CPU supports QC but dont have additional QC charging components.
Safety diode is meant to keep voltage constant and within limit below 5v for our device. Use of QC charger draws higher voltage and overheats the diode.
And if it crosses above 5.5 v then it short circuits the diode and the diode prevents further charging and finally stops the charging to protect the mainboard. If u want to save ur phone and battery for long term then use stock charger.
