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
My g5 gets pretty hot(40-45°C/104-113° F) while fast charging with QC 3.0 charger,is this normal or am I just being paranoid?
I think if android gets to hot it automatically shuts down at 150 f I think? 70-90 seems like the normal temp maybe more or less depending on what your doing. I would imagine it be on the higher side while charging. What app you use to monitor temp of phone while charging? I will test mine and report back results.

That sounds normal if you have the display on or have a demandingly busy/weak WiFi/LTE signal while charging.
Also note you will get throttled charging speed the warmer it gets - the system has several monitors on-board to protect from getting too hot. You can see what the system settings for temperatures are in root > system > etc > thermal-engine-8996.conf.
I attached a screenshot of some relevant settings from that file. The thresholds are degrees Celsius; you only get optimum charging speed with display off and temperatures below 42 °C. (Always-On Display setting doesn't seem to affect the "LCD-On-Monitor" for this purpose.) Temperatures 45°C and below are equivalent to 1 amp charging - slower but still decent. Any higher and significantly slow throttling occurs.
As a side note, you can physically verify this kind of info with an in-line "USB power monitor" device. It sits between your charger and cable and displays the volts and amps for you. Usually costs $10-$20 USD. Make sure it supports at least 9 volts and 4 amps to monitor QC 3.0. (Mine has a range of 3-20V and 0-4A.) Handy for figuring out if your charger or cables may be faulty and verifying charge rates.

you can improve the temperatures if you tear down the phone and apply mx4 in the cpu and ram, 10/15c of improvement at least. the g5 have ****y thermal pad, and cooling sistem.

Sorry for late reply,I am using accu battery which shows complete statistics.Anyway can you please tell me whether it will cause damage or not to my phone? Touching the phone while it's charging and screened off feels really hot.

My screen is off and its averagely arround 42-43°C but it's still charging at maximum speed i.e around 2900 mA and could you please tell me that all those temperature monitors which show live temperature are showing CPU or battery temperature? Because if it's battery it's written that the temperature shouldn't go above 40 and since it's going,wouldn't that be dangerous?

"Li ion batteries offer reasonably good charging performance at cooler temperatures and allow fast-charging in a temperature bandwidth of 5 to 45°C (41 to 113°F)." The battery can charge between 0 and 5°C and above 45°C but it will be reduced speed.
The discharge temperature range is "–20°C to 60°C (–4°F to 140°F)"
http://batteryuniversity.com/learn/article/charging_at_high_and_low_temperatures
Anecdotally I've had my HTC Rezound battery abused many times with charging (slowly) at or above 45°C. One night I even had it around 65°C when I fell asleep with it on a faulty charger *and* thermal safety on the OS disabled. After many cycles and abuses it had a very slight bulge and maybe 50% original capacity. Needless to say I bought a new battery, but it shows the limits in a proper li-ion are well above the charging/discharging temperatures.
You should only worry about performance degradation above 45°C and not approaching anything "dangerous" until perhaps north of 60°C.
I'm charging my G5 right now and using AccuBattery app as well, first couple of minutes I'm at 34% and 40°C with screen off which is in line with your results. I'd call it warm but not alarmingly hot. I'll test more charges on G5 by tomorrow.
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!!!

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.

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.

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.

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.
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.

Anyway, I have a little weird thing :
This battery monitor stats shows me different SOT than GSAMBatteryMonitor.
GSAM shows 2 hours more (wich I think wrong), and this delay grows while battery dercreases.
Do you have this app showing the same stats than colorOS battery monitor ?

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.
