I am getting about 700-1300 mAh charging rate and most of the time it shows "charging slowly". I am on stock charger and cable and i used to get 1800+ mAh by this charger before. What causing the issue? Or how do i fix it? Currently i am on ViperOS with latest firmware 7.9.7.

flash this and dont check for mA value right away. Give it some time.

Hi,
I'm trying to charge my phone but I'm getting an error "charging paused, battery temperature too low", I replaced the charging port but still same error, wireless charge is giving same error.
Any help
Maybe the battery or the cable connected to the battery to the motherboard is loose.

I replaced the battery and the charging port but still the same issue, I noticed that on TWRP the temperature of the CPU is fine but on the system is -20C, any suggestion
is there any way to charge the battery outside the phone?
is there any way to change battery temperature on system, so that way maybe the phone will charge
I'm interested on this one... I know its old but just happened to me. Did anybody fin a way around this? Maybe a battery temperature spoof app?
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
I am using the latest LineagOS. I thought Le Max 2 has QC3.0 support which should let it run at 12v charge voltage, but it does not.
The best it does is 9V and 1.6A (measured using usb meter) totaling to 14.4W. I tried the phone at room temperature, also cooled it down in fridge and tried again. Results are same. The battery was 1% - 3% at start.
Is this normal? I calculated and 14.4W if batteryt was charged to 4.35V makes roughly 3300mA which sounds rather low. I expected phone to go around 4100mA at least while charging.
More importantly, it never switches to 12V charging voltage. Is that normal?
my phone is going up to 4100mA while charging. On some roms you have to enable quick charge in your phones settings.
@LivingLing did you test with a program like Ampere or using a USB meter device? Because your ROM may be giving you incorrect values and it can't be trusted.
There is no quick charge option in LineageOS but I can see that phone is using quick charge because charger increase voltage to 9V. I am trying to understand why it wouldn't go to 12V

No i didnt used anything like that, just mentioned the values given by the Rom. But my phone charges Form 10% to 100% in like 15 minutes. So thats actually pretty fast in my opinion.
That sounds impossible, make a screenshot from the charging graph please. That would be something about 10A charging current...
I get about 4,5A when I activate QC on the EUI
@LivingLing Your phone must be broken if you can charge 0 to 100% in 15 minutes. You can't really charge a lithium battery very fast after about 80% and thats why quick charge implementations never talk about 0 to 100% charge time.
With lithium battery, most implementations set the input voltage to about 4.35V and battery charges as fast as it can pull power. This slows down when battery is near full.
I recommend you to get a USB meter, they cost few dollars anyway and quite cool devices.
Guys recently i just noticed my device charging slower tham usual with the stock charger as well as other qc 3 certified devices and it also dsnt show the quick charge logo in the notification drawer!!!
Iam in 9.6.25 global rom can any body confirm if its a rom issue or my specific issue

download amps app and check current rating feed to your phone, fast charge > 2500 mA, if lower, try change your charger.

After the update mine also shows 3hr's to charge and slowly charging. I brought the phone 10 days back and updated to this 9.6.25 a week and facing this problem.
Have no problem at all with Poco f1 Miui 9.6.25. Charging time is around 1hr 45 to 2 hrs if not mistaken.

Ive already tried it it shows almost 1450 ma
And ive tried with different cable ... different charger and even qc3 power bank no luck so far could it be a hardware issue in my phone?

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.

Don't worry its just a software issue I just flashed the miui 10 beta Rom and now everything is fine it shows the QC logo also
Me too facing the issue. In the screenshot, charging at 18% and showing 920 mAh
Me too facing the same issue and i am on Miui 9.6.25 as well.
I just had a chance to check it, as I recently upgraded to 9.6.25. Well, no changes for me - there is QC icon next to the battery and Ampere shows current reaching 2900 mA.

Can you upload a screenshot of ampere while charging
Here you are.

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.

Iam in 11.0.5.0 global rom can any body confirm if its a rom issue or my specific issue
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.
Do you guys also experience slow charging or is it just me?
I know I am not supposed to game while charging but still. The battery either remained at same level or got deterioated sometimes while charging and gaming.
Apart from gaming, charging does seem slow. I installed Ampere app from playstore and it averages around 2350 mA. Can you guys check and report back?
Note : Everything is stock from the box.
I think you answered your own question by saying your playing games while charging. That's why it's not charging like it should. Just don't game and charge

Battery temperature can have impact on charging speed too. What Ampere says in this regard? In my case I observer current levels reaching 2900 mA, battery temperature showed by Ampere around 25 Celsius
Charged from 0 to 100 within 2 hours. Phone was switched off. Original charger and cable.
With aftermarket QC3 capable charger, ampere shows 2800mah+ consistently (I don't have the original charger to compare, but with Samsung's s8 original charger I get the same numbers).
