Maximum charging rate with Ampere App - Xiaomi Redmi Note 3 Questions & Answers

1. install Ampere from Playstore
2. connect your phone with charger
3. open Ampere
4. wait at least 5 mins (don't let the screen turn off)
5. post your screenshot
you may get lower ampere when the battery is more than 80%.
better test when battery is below 50%
you may also get lower charging rate if u use cheap usb cable
currently I'm using RR rom with the stock 2000mA charger.

Phone takes more than 24hrs to charge

My phone has to charge more than 24 hours to fully charge...I'm using the stock wall charger and i'm on KitKat 4.4.2 Teamsek unofficial v42 using Boeffla Kernel 2.2 beta1. What to do ?

Maybe the charger or just the cable may be faulty so you need to check first.
Second, if you are turning off wifi from the toggle, then try turning it off from the settings manually. If you think this is related to the ROM, then you can ask in the relevant thread for assistance.

How do i reset my battery and deep charge ?
1. Slow charging is because bad charger (if you have root and for example Boeffla kernel, you can force fast charge).
2. Wifi always on is because you have set in wifi -> advanced ->always allow searching for accurate location.
The names of path and settings are probably wrong, because i have Czech language, so i dont know how it is called in English.
Solution:
1. buy new charger
2. turn off searching wifi for location purposes.
Before buying a new charger altogether, you can just test what happens if you try to charge it via usb port, you should have a microsd cable lying around somewhere. USB ports only give 500mA but it should still charge in a few hours.
If it still doesnt charge, it might be either the charger module in the phone or the battery. I had a faulty microusb input in my old i9100, it prolonged charging hours.
charge to 100%,open rootexploer ,find /data/system/ba tterystats.bin,delet it,never charge it until it drains completely。
Switched chargers and now it charges in 3 hours...
Since you're on Boeffla Kernel, you can download and use "Boeffla-Config" and increase the AC charging current from 1100 mA to a higher number and turning off Ignore Unstable Power and Ignore Safety Margin.
And increase USB charging current from 475 to 500 mA this will provide you with faster charging speeds.
P.S Increasing USB Charge Current To anything beyond 500 mA has no effect on USB 2.0 ports since these ports provide only 500 mA output current no more.

Takes 5 hours or more to fully charge wtf

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

What is the ideal Ampere score? I go from 90 to 200+ mA
But never pass 400 mA

It should be between 500-2000 mA
400 mA is like you charge it from computers usb.
Change your cable and try again

Test quick charge with ampere

I use ampere app
For me show maximum 1500ma and during on or off quick charge mode didn't change ampere level
How much for you?
My rom is couco92 but after enabling quick charge my ampere don't up

Quick Charging is 3020mA for me. Charges from 20% to 100% in about 60 minutes.
Edit: I'm using this one on Oreo DU with x829 btw: https://www.aliexpress.com/item/Twi...0-For-iphone-7-8-Plus-X-Wall/32838242756.html
I am on Oreo DU and max charge is arround 1300mah. My original charger came broken, so i am using 2A one, also qc but 2.0, original cable is also faulty as with it it charges some 400mah.
1300mah is fast enough for me.
Heyyo, eh I haven't found Amphere to be that accurate to be honest. I'd recommend accubattery over it.
For charging speed? You pretty much need to leave your device charging with the screen turned off for at least ten minutes to get an accurate quick charge reading.
I've seen it hit up to 2500mAh with stock charging brick and cable.
Max approx ~3000 mA. But you should note it's when battery level is low. Charging speed and current depends from battery lewel, higher battery lewel means slower charging
I didn't measure, but from 3 per cent to 100 75 minutes

Have your problem been solved? I'm facing same issue and it happened after flashing cuoco92 room. After that I tried most of Oreo and nougat rom but none of them solved my problem except slim7 rom.
---------- Post added at 10:08 AM ---------- Previous post was at 10:00 AM ----------
My original charger and cable working fine as slim7 rom let me charge my device quickly but other roms not. Slim7 gives 2900 max current on fast charging while 2300 current without turning it on. In others it gives 990mah or sometimes 1560mah and doesn't matter fast charging enabled or not. I also tested my charger and cable with le 1s and showing 4000+ mAh current. Don't know what happened to my device while. I always prefer clean flash included internal storage during flashing new rom.

mipad 1 charge control?

How to control charging speed on mipad 1(mocha)?
I think the original charge speed setting of 9v 1.2a is not good for battery, it's too fast. I hope it can be slower.
And I also want to stop charge before full charging such as when it reaches 85%.
Is there any way ? Thanks.

Issue with charging

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.

So, what was the maximum voltage you could set using Advance charging control app?
i.e what is the max voltage limit of poco f1
Also do you have any other charger than the stock one?
Charging cable issue?
Mine had issue with the charging cable.. tried with other charging cable it worked properly.. original charging xable got damaged witin 4 months of use..

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 .

Don't know about other charges but i use stock charger and mine charges fully within 45-55 mins(0-100).
Stock charger brick is only fast charger 3 whereas our poco supports fast charge 4.
You can try ambrane or razer fast charger 4 brick for charging your device faster than stock charger

Use Advance Charging control App. It gives you volts as well mAh speed by which your phone is charging or discharging.

There are many applications on playstore to check.
Ex:- AMPERE , ACCUBATTERY

As I suspected, you're aren't aware what the ampere app is for.
Here take this for starters:
https://youtu.be/PvgLEii7f0w
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..
