Hi,
Question for the redmi note 2 users.
What charger do you use to charge your phone?
When i used a normal usb wall charger that I used for my HTC the charging was very slow.
Switched it to the original charger that came and it was a lot faster.
Why does it take forever to charge on a normal charger?
Also what do you guys do if youw ant to charge throughout the day via a PC and when travelling in car charger?
Am i missing something?
Because the original charger can provide up to 2A of power. Just check the output spec on the charger usually it show the voltage and amp like this: 5V = 2000ma.
USB 2.0 can provide up to 0.5A
USB Fast Charge on some laptop can provide up to 1.2A (CMIIW)
All charger have the printed output spec.

I connected a new samsung fast charger and a message immedietely came up saying too much power overheating.
So basically I just need a charger that has an output of 2A?

I need one for the UK.
Can someone send me a link for one to buy.
Also if you want to charge in the car do I havw to buy a car charger that supports 2A?
I assume same goes for PC?
So higher the Ampere number from a charger so faster it load ,BUT to high can damage the Battery so you are good with 2A or 2.1A think it also gives for the UK cause its only thing of voltage change

This is what I don;t understand the samsung fast charger is 2A isnt it? " It outputs 2A for ultra fast charging, so your S5 will be fully charged in no time."
Has anyone from the UK replaced the 2pin charging plug with a 3pin plug that maintains the quick charge if so which one did you buy ?
I use PC USB 2.0.
I don't care about how fast it charges.
For me the slower the better.
A 2 amps charger will work fast like the original?
I use OPPO fast charger..

I have an old 0.7A charger and was told that a 1A charger would be faster..
But how far higher can I go? Is there a 2A charger?

1A is stock for S3.
Maximum recommended is 1.5A,more may brick your whole device,if not the battery.

I guess using modified"boeffla or googymax " kernels will let your phone charge much faster
Maximum rating of the charger is irrelevant, the phone will only draw a safe amount. If you override that limit then you may blow the internal charging IC or rupture the battery.
Don't post questions in the general section.
The S3 can't charger faster than 1A, it will only draw what it can, I've used a HP Touchpad 2A charger since the day I got the phone, it still won't draw more than 1A. You can use custom kernals to draw more, but you'll find lots of stories of people who did it and fried the charging board.
I tested using 1.1Ah, and for the storioes I've read, it's the maximum value you can use with security.
Hi, you can have more than 1A, but you need to change the limit with boeffla (i made it for the USB charge)

Using 1.2A from months in boeffla kernel without any trouble, using stock charger.
I tried 2A once and it was fast (0-100 in 1hr) but its not recommended 1.5 max
Also I increased charging speed to 1600mah that time and it was working

Dramatically increasing charging current will also dramatically decrease battery service life
Just get a second battery and desktop cradle, instant recharging without any wear on the phone motherboard.

Hi, i am getting a new charger for my tablet pc which uses a 5.35V 2A output charger and was wondering whether i can use this to charge my galaxy S3. so that i do not have to carry 2 chargers?
IS it advisable?
My S3 came with a 1A charger, my wife's S3 came with a 2A charger. I used her charger a few times and it worked fine. As of last week my charger is working fine, if I use hers with my phone I only shows "USB" in the battery info and takes forever to charge. I don't know if her charger did damage to my phone/battery but that felt strange, so I stopped using her charger.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Redmi Note 5 can charge. A higher rating indicates that it charges extremely fast.

last week i bought a Redmi 5 Plus 4gb/ 64gb Global then i tried to test charge time and quick charge.. 3-4 times with a qualcomm QC 3.0 charger and another QC 2.0 charger.. The results are similar: all about 2 hour.. the charge time with Xiaomi's own 2A Charger it take about 2 and half hour. i know its good but not so good.. By the way i notice that when test with QC3.0 charger it can not charge with 12V.. (i used a usb tester to see voltage and Current) i just saw 9.30v as max voltage. its behave look like QC2.0 not QC3.0
Snapdragon 625 should be support QC3.0 isnt it?
Are there anyone test quick charge?
I have a QC 2.0 charger,takes about 2 hour to fully charge my R5 phone... don't have tester to measure voltage,but phone doesn't heats up,its around 28 C when charging.Charger does
all my qc3.0 tests take 2 hours too. i see my qc 3.0 charger work as qc 2.0 charger. maybe my charger not work as qc 3.0 maybe our phone not support qc 3.0 we will see... i will buy a new qc 3.0 charger and i will test it again then i share the results here too.
using moto g4 plus turbo charger . charging speed 2600+mah . takes approx 1 n half hr.

welll my new charger delivered me from china, so i tested it a few times. its better than my qc2.0 charger and my other qc3 car charger ( i think its not qc3.0 its just qc2.0 ) My new charger is not as good as expected.. charge time is an hour and 45 minutes. .. its mean 15 min better than qc.2.0 ... i saw 10.1v and 1,35 amp on my usb tester, it could be 12v... Anyway we can see that the phone supports qc 3.0 but not at all its need powerfull and good qualty QC3.0 charger, so if you want to buy a QC3 charger i I recommend that you need to research well.

I'm using my old charger from vivo , is this normal charging speed?
I tried a charger that is certified by Qualcomm with QC3.0 and got around 2470 mAh (4.171 V)
PLease help! I am facing some battery calibration issues. The phone hardly charges up to 100% no matter how long you charge it. It just gets stuck at 96% or 97% and then the phone goes off at 19% on usage. I have tried different calibration apps to no avail. I even did a clean flash using the miflash tool, still no luck.

You are not alone. R5 plus and some another xiaomi device, sometimes we see this problem. And there is no software solution. Wipe, mi flash, battery calibrationi root... I tried everything but no luck.
Only solution is;
Remove the back cover (i did it, its not so difficult.)
Remove the battery connector plug
Wait a few seconds
Plug it back.
Thats done. Problem solved.

Can you please confirm whether it supports quick charge 3.0 ?
I`m about to buy a mi quick charge 3 adapter.
You can post screenshot of your file located at /sys/class/power_supply/battery/uevent
Just want to be sure. That`s it.
I know I might be late but I'm getting around 4.4v is that normal?

Actually I heard it's fine. I'm using quick charge 3.0. Redmi Note 5 AI/Global. Fully charges from 0 in 1hr 50 mins.

The phone ships with a quick charge 2.0 charger. The phone supports 3.0 and also 4.0 for India markets. Mine is Malaysian so it's 3.0. With stock charger it takes 1 hour 20mins + to get fully charged. Not too bad. With a QC 3.0 charger (Using my mi max 2 charger) it takes about less than an hour to get fully charged based on estimates. Charges quite quickly to 70% so stock charger is actually fine.
I think it supports USB PD as well, I used my pixel 2xl charger and it showed that the phone is charging rapidly, will do another full test and post results!

If it's the global version, it should be QC3.0 . QC4.0 is only for India if I am not wrong.

I don't think QC 3.0 is that much slower compared to QC 4.0. It's not like Oppo's new charge system, now that's quick haha. QC 3.0 is fine. I am still using QC 2.0 and it's all good no issues with it.

Phone supports quick chargers from xiaomi only. I have tried 2 different qc 3.0 certified chargers and both get 1800mah to my A2. My charger from my old Mi5s plus works fine and gives 2400mah.

I got the cheapest qc 3.0 from Amazon, tycipi or something like that. According to ampere app it is providing 2400 mah, it charges the phone quickly
I got the global version, so only QC3.0.
I have an Aukey PA-T8, 8 ports 5V 2.4A, 2 QC3.0 ports.
On 2.4A port, Ampere say 1800mA.
On QC3.0 port, Ampere say 2300mA.

If you own a Global Version, your device will only support QC 3.0. Only Indian Variants support QC 4.0
My A2 unit is behaving quite strange, first let me say that Ampere is not so reliable as a USB power monitoring device, which I have (this unit gets you also the voltage which is being supplied to the phone).
MY measurements (with supplied USB-C cable) are:
- Stock charger: 1,6A voltage 5V
- QC 3.0 charger: up to 2,4A voltage 6,5V
- QC 2.0 Charger (works with Asus Zenfone 2 and Galaxy S8 on quick) - sometimes ZERO - just shuts down after a minute
Other 2A 5V chargers often not more than 0,6A (depending on cable)
So, A2 is very sensitive with cables and charging electronics and probably cannot accept 9V.
Global version.
Sometimes the phone when plugged in charger shows "Charging slowly" and sometimes "Charging Rapidly", What's up with that?

With a Power Delivery 3.0 charger and smartphone off, it can surely be charged with a voltage of about 9V.
I don't know if it's possible also in other cases.
Is the QuickCharge 4.0 a software or a hardware feature in the Indian version? Just wondering if QC 4.0 can be "unlocked" in the global version through future software tweaks?
With the stock charger , it's charged after 3 hours it's normal ?

does anyone tried to charge Mi 9 with this Baseus charger?

I think it's just Quick Charge 3.0. You should buy the 27W charger imo. But i could be wrong
I have it, it does quick charge but not charge turbo
Good I stopped by XDA before purchasing it.
It does say if you scroll down on its specs it's a QC4 charger, but I assumed the described output would be a sum of both USB ports working simultaneously.
Already posted about it some weeks ago.
https://forum.xda-developers.com/showpost.php?p=79530777&postcount=73
It's indeed just a QC 4.0 charger. Will only do 18W.
Hi, I have one. For it to work properly you have to have the cable of more than 30w.
Load much faster than the original that comes in the box. I did a quick test from 75% to 100% with the phone turned off and charged in 25min; so you can assume if it's fast or not.
WTF ; does this phone even do QC4 ... the Xiaomi offical charger is 3.0 and I bought a $68 dollars Belkin QC : 4.0+ offical as per reviews and it caps out at. 3470 : it NEVER has said fast or TURBO and it ofen Ampere reports 1800 mah ? Can anyone explain this in any way

I suspect that Turbo Charge only happens with the 27W factory charger.
Because my Hama QC4+ charger, certified by Qualcomm, charges definitely faster than the 18W charger found in the package, but does not say Charge Fast or even Charge Turbo.

Call me crazy but I think it will charge the device at 27W speed.
A lot of people don't seem to realize but the "Xiaomi Turbo Charger 27W" is actually QC3, not QC4+, and it does charge the device at 27W. If you find a QC4+ charger that supports 27W and up, you will still get 27W charging but you won't see "Charge Turbo" because it will use the better, newer charging standard.
This can make charge turbo QC 3.0 and it's cheaper and with more ports:

Yeah but it can only charge at standard QC3 speeds, aka 18W at max. 9V/2A like the original one does. But the original one can also do 12V/1.5A. So it does not "Turbo Charge".
Careful many poster here are confused. My BELKIN true QC4.0+ never ever charged over 3200mA and averaged out at under 2200mA. Posters who speak about things without testing their theories are really frustrating. Do yourself a favor don't believe this phone accepts QC4 or QC 4.0+ (at least not @July 2019) only QC 3.0 NON FAKE xiaomi 27w can do the 4600mA + it would seem. Turbo charging is required for extremely rapid charge times. Make sure you get OFFICIAL 20V 1.35A from Xiaomi for Turbo Charge sustained charge and under one hour 0--100%
I also purchased a QC 4.0+ Hama DC charger cause Xiaomi doesn't make a DC charger to my knowledge. Guess what ; 18w ish charging speeds .. no Fast or Turbo classification ...
XIAOMI Hoe do you call this phone a QC 4.0/4.0+ unit !!! Cause look close at the charger Turbo pictures they are all using the "Original QC 3.0 Xiaomi charger that we ALL should have got in the box. Instead many of us have wasted tonnes of money and time buying useless to us QC 4.0+ tech that doesn't work or WORSE fake chargers that don't do more than 18w !! By the time we we have ordered 3-4 different chargers trying to get it to work we have to order it on Ali or gearbest or Gearvita. Cause the company does make them after all!! Enjoy the brutal shipping fees and heavy wait times. Well we order this and that trying to get the darn thing to work. So annoyed right now
Hi, I got the original charger and this if it gives the turbocharged 27w charge, however the baseus charger charges the same as the one that comes in the box or with the wireless charge.
I made this short video: https://youtu.be/nFBoPxORzEg
https://forum.xda-developers.com/k20-pro/how-to/mi-9t-pro-30w-charger-experiment-t4003595
read this. Also tested with a mi9 that my fried had. same result.( Turbo charging up to 30W using the baseus charger)
Posted for those who end up here like me and read mixed info
I also have the Baseus charger mentioned above (BS-EU906), the variant with 2 usb A ports.
When I charge with the cable from my samsung galaxy tab S5e it charges with a bit over 4200mA 20w-21w.
But when I charge with my Baseus 2m 5a capable cable (CATSS-B0G), it never goes above 3400mA ~14w.
It still chargers fast, but it is not what was advertised. Both the cable and charger are rated for QC3.
Baseus GaN charger 65W + Baseus 5A cable reaches 5000mA in Ampere, which is assuming 5V (that's what Ampere is assuming), equals to 25W. The fact is voltage in QC is never stable, it's the factor that allows it to dynamically supply power based on various parameters: battery temp, device temp, battery capacity and so on. If you have a USB-C USB doctor (and it should be more accurate than any software based monitoring) you can watch yourself that both the voltage and current are alternating constantly.
Hi Guys,
I know we always have to use the default charger but this is also a fact that the fast charger is not always good for the phone's battery life. We can use it sometimes when we are really required fast charging.
I have a Xiaomi original charger 5V, 2A. I use to charge my device 20-80% with this charger. My phone will not get heat up like it compared to the situation when I charge with a fast charger.
Please tell me, is there any problem if I'm not using the default charger that comes in the box with the phone? I'm using that cable but with the Xiaomi slow standard charger. Will it be safe for both the phone and charger?
Thanks,

yeah thanks for the reply.
sometimes, in the case of need, I will use the fast charger otherwise I will always go with standard 5v 2A charger.
