I got a new Qualcomm quick charge 3 certified charger ..but according to the readings in ampere app ....the output is like 1750 mA ..but the same charger with note 9 gives an output of 2900-3000 mA ...is this the phone problem ...if anyone has the same problem ....and found a solution ..please help
It does not charge at full power all the time. There are several charging states and the full power one is from 15% to 65%, I think.

Yeahh ....I checked that also ...I measured the mA from mi charger ..it was 2800-2900 mA ..the new charger gives about 1650-1750 mA...at 40% charge
The kernel limits max current to 2800ma, but you can increase it with a custom kernel. It could be that your new charger is not properly supported.

Temperature is just a part of the variables. Other variable to consider which was not stated was voltage.
QC 3.0 spec shows that it can charge at a voltage between 3.2V to 20V by doing +/- 200mV increment/decrement. Looking at the current alone is incomplete.

Can anyone tell me quickcharge 4.0 charger?

I received my RN3SD 3gb yesterday. I was testing the charging rate today because I felt that it was charging slower today than yesterday. I used the program Ampere to check the charging rate. Market link is:
https://play.google.com/store/apps/...lay&pcampaignid=APPU_1_aYcvV5ziJMG0uATH1YSoBw
Well, in getting around 1000 mAh on an average with a max of 1300 mAh and lowest of 230 mAh.
I read somewhere that the charging rate should be around 1900 mAh. I would appreciate if I got feedback as to what the normal charging rate is for you guys (ideally, checked in the same app). And please let me know if I should be using a different app. Thanks.
info:
Unrooted ROM MIUI Global 7.2.2.0
Yes u r right, i m getting 1900 mah with 16 gb model ,ampere app is ok. Maybe try factory reset
Ampere showing 1.9k mA to 2k mA here.try check your cable and charger.
How that matter and what doest it affect ? Its about charging time or battery life ?
I'm gettgin 1550mAh
What was the battery percentage when you opened Ampere? When it's getting up to like 90 % the current goes down.

When I opened Ampere the reading always varies. Sometimes is 490 sometimes 1150, the highest I've got is 1650. The charging cable and the charger are brand new. Even tried charging from a USB power bank, got about 500mah. What can be the reason for this slow charging. These are all values foe when charge is less than 90%. What can be the reason?
Depends on what powerbank you have. Most don't support high charging rates, (although there are some more powerful ones from xiaomi and lenovo on the low end market).
On another note,
I am wondering about the maximum Voltage and Amp we can charge with safely? i tried 3 differennt ones; 5v 0.3A, 5v 1.2A and 5.2V 2A. All seem to work fine, with the last one i got about 10% per 10 min with a value of around 2100 Mahor higher , but i am not sure if this is a safe way to charge the device?
Does anyone know what is the maximum safe charging value?

There are regulators inside the phone that step down the voltage to charge the battery, i think it's a 4.35v cell but the phone will regulate the charge. So long as the USB voltage is within spec it's fine, many chargers have 5.1 or 5.2 volts to combat voltage drop with higher current over long leads or leads with small conductors.
mine about 1.900 mA
Is this normal at all? I am using stock charger and both
Used global and currently RR rom. I Google for little
Bit and found out that people are charging for only 2 hours
With just the stock wrong and stock charger. Source: https://youtu.be/YedjT3ANTSE
It takes 180-280 min and maximum mA on Ampere. I don't know what these digits tell at all.
Is my phone defectice?
This is really annoying me.
It takes around 2h20min..if its chargin around 2A...with guyver or radon kernel it goes hl to 2.4A, more then that would heat too much.
You might have faulty charger? Have you tried any other charger?what does ampere says? ...
Try another cable... Cable makes huge difference too

Try to charge below 50% from current battery level.my stock charger rating 5V 2.5A..can get around 2.2A reading from app.
Its starts slower then it gets faster , from 10% to 100 % in under 2h , so its working properly.

You guys don't use the search function on the thread and just keep on making new threads about the same issue.
It has been well documented now that the charging slows due to thermal throttling. The hotter the phone the slower the charging. If anyone wants to test this, charge your phone for 5 mins before an air conditioner and measure the charging speed using the app called 'Amps'.
You should see the charging speed at around 2700-2800mah provided your phone temperature is quite low.
Otherwise, take a chilled watter bottle from your fridge and pour it generously on a towel. Now place your phone on that towel and charge you phone. As soon as the temperature starts falling to around 32-34 degree celsius, the charging speed will increase.
This is built in safety feature. The charging slows when the battery temperature is around 36-37 degree celsius as per my observations.
Cool you battery to around 30 degrees using any method you can and then check the charging speed.
Not your charger, not your cable...its mostly the charging algorithm with built in thermal thresholds which is at play here.
DO TELL ME YOUR TEST RESULTS.
I just found this thread - I have similar problem but it's rather not connected with temperature.
After one of software updates I discovered that quick charge is not working. Maybe it wasn't connected with update but this is how I see this.
I was waiting for software updates and hoping that they will fix my problem but nothing was changing.
Recently I decided that maybe factory reset will help, but unfortunately no.
After this reset I was checking many chargers and it appeared that with laptop charger (with USB C output) quick charge works! I was checking parameters in application 'ampere' and there is information that this charger is AC, and rest is USB. So it looks like QC works but....
Please help, how can I make quick charge works again via standard quick charge charger.

I want to clarify that my Poco on fully stock 11.05 charges as fast as any previous version of MIUI.
I take care of my battery. Charge till 80 and never let or go below 20.
If you can maintain the variables, and it still charges slow then you have issues with battery IC or the battery itself.
The highest I got without ceiling fan and without ac is 1590 mA. Maybe I got higher other times but I installed the app just for this post.
Don't rely on software reporting.
Do you have a multimeter?
Ambient temperature plays a HUGE role when it comes to battery, even if it's 1 degree more or less.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Realme X2 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Quick isn't the word. It's amazing seeing how fast it charges.
Can it be charged with a 5 volt charger?
I think I have a problem with fast charging.
Yesterday while the phone was charging, electricity in my house was shutted down. When it came back, I can see than now, I charge 1 % on 35 seconds, instead of 20 sec before.
Could it have the battery damaged ? I doubt so, buty it's strange.
I tried when battery was 82%
Maybe it's quicker when battery is low ?
What's your thoughts about this situation ?
Thanks !
Edit : Okay, after 85% it slows down, but before it's okay

Yeah it slows down towards the end I'll go from 0-99 in 28-30 min then takes some time sometimes to get the last 1%. Battery life is also incredibly good.

GSAM shows 2 hours more (wich I think wrong), and this delay grows while battery dercreases.

Greetings.
I got my X2 Pro about 2 days ago. Charging speed is even better than advertised, as it takes less than 30 minutes to reach full charge. But phone usually gets too hot when fast charging. Do I experience this problem alone or do you guys too? Kinda worried about battery health in the long run if it gets too hot everytime I charge it.
Thanks before

Same thing here, so I don't charge more than 40 - 45% at a time.
If my battery is below 50%, I charge in 2 times with a 10 min pause.
Doing sop, you don't reach hoptter than 33 degrees instead of 38+
I can't seem to get a decent standard charging from 5V 2A chargers or Powerbanks, even a QC3 Powerbank only delivers 0,9-1A.
I only get about 900mA according to the Ampere-App. {On the contrary, I even get 1,8A from the original wall plug at 80% SoC).
Do you also struggle?

Same here. I used a 9V 2A charger, and it won't go more than 1100mA.
I wonder if this is a detection error from the apps. I think they don't consider the dual battery layout and only display half of the true value.
The error that the app "charger tester" shows let's me think this or does support my theory.
All apps seem to not be able to show the correct current flow because of the dual-batteries.
I found the engingeering mode and can confirm that the phone charges with 5V 2A on dumb chargers.
And also supports QC 18W with 9V 2A
As well as the Oneplus 20W Dash charger with 5V 4A.

Super VOOC (and also VOOC) have their own protocol of charging mechanism. It's not the same with other quick charge method like Quick Charge 3.0.
You will not have VOOC charging if you are not using right adapter and right cable. You try use Super VOOC charge with other USB cable, VOOC charging will not work.
So when you using other adapter or cable, you'll got standard 5V charging max 2A.
The stock charger says it gives output of 18 watt . But in my case maximum ouput goes to 1.5-2 amp/3.5-4volts which is very less . It would be helpfull if anyone tells how to get 9volts or 12 volts.

Are you on stock rom or custom rom?
Stock
MIUI 11.0.9
If you are ok with rooting your device. I can tell you how to do so.
1. Root your device.
2. Install Advance charging control app(AccA) .
Link- https://f-droid.org/packages/mattecarra.accapp/
3. Give root permission.
Done.
(Don't install the magisk module app will work fine without it. The magisk module is installed and forget kind of module which you cannot modify to your own need)
Now you can set the speed you want (if your device suppots the spped you typed in it).
Its not just that, you can limit the charging % after which the charger automatically disconnects. I find it very helpful when i charge my device overnight. Automatically disconnects after 95%.
It also looks at your thermal of your battery. You can set your own temp % after which it starts cooling down by limiting the current/volt to the battery.
I personally suggest this app.
Thanks to @VR25.
Hope it works for you.
Thanks . Will try it.

Change cable, then change charger. Usually its either of those two. If it works, good. If not then it might be an issue with the software try to reflash (backup first). Worst case scenario it's the port
The issue is solved for me (Stock Rom ) . Bought new cable upto 3amp . Charged 87% in one hour (screen off) .
Tip : Keep the temperature below 35 degrees .

As I suspected, you're aren't aware what the ampere app is for.
Here take this for starters:

The ampere app is for........amperes, it does not show charging voltage. It's the battery's voltage. Same is the case for accubattery.
I use Franco kernel manager app from playstore and it shows watts, which is at least somewhat believable.
I don't know about ACCA because it doesn't work without root and works on very specific phones.
Try with Franco kernel manager app(root not required) and check the watt.

You mean *1 hour* 45-55 mins(0-100)?
POCO F1 has 4000 mah, or 4.0 A * 3.7 v = 14.8 Wh, so if you charge your phone at 14.8 W for 1 hour then it will go 0-100%
or it will take 1 hour to charge your phone from 0% to 100% if you charge at a constant 14.8 watt. Which never happens, because hardware thermal throttling and software thermal throttling, after 30-50% the watts will go down, in the last 80-90% it will really be low. Even if you remove all thermal throttling and charge your phone in ice cubes, still because it's a 18 WATT QC 3 charger, it cannot charge in 45-55 mins.
What you're saying is most certainly impossible. Either that or your numbers aren't accurate, like it wasn't from 0-100% maybe 25-90% or it wasn't 45-55 min , maybe an hour and a half or you don't use the stock 18 watt qc 3 charger, or your battery is defective or you don't have a poco f1..
