take special note of the last two, when stock charging was at 1900mA, fast charging cut the charging speed in half to 1000mA. so i ask, what does Fast Charging do? or what is it supposed to do?

When your phone is screen it locks the charging speed to 1200mah to keep the heat down. Just turn off the screen its gonna charge at 1900mah

It's all about running processes. Most devices when in any kind of efficient mode such as this - if the screen is disabled, the phone puts it into a mode knowing it's not being utilized and will either kill processes or temporarily stop them. So the change in charge speed will depend on screen on/off. Using AC outlet as opposed to a USB 2.0/3.0 on a computer or laptop will always be faster.

So we just upgraded to Note 3 from our galaxy 3 (wife and I)...
I noticed the charger is a 2 amp charger compared to the SGS 3's 1 amp.
I started reading some threads here and found out the USB 3.0 cable will not charge the phone faster unless it's plugged into the computer.
Apparently the PCM also limits the phone to charging at 900ma. (not verified)
so I'm curious now.... at what amps does this phone charge? I'm trying to get a spare charger to keep in the car, and also trying to get a usb car charger if I can benefit from the 2.1 amp one instead of the 1 amp one that's in there now....
Can anyone tell me if I should get a 2.1amp charger or stick with 1 amp chargers as the spares if it'll still charge at 900ma?
I'm using USB 2.0 cables btw. (unless I can charge faster with the USB 3.0 when plugged to a car charger or the wall, which I apparently won't from my research here)
While I await for responses, I will plug the charger into my voltage/amp reader and we'll see how much power is being drawn, which might give an idea as to how many ma it's charging at.
For whoever that wants to know this information, these are my findings from my meter that is able to measure how much power is being drawn (kill a watt P3)
with the stock charger and USB 2.0 cable (3.0 made no difference) the phone will charge at 900ma with the screen on. If the phone is shut off, or screen is off, it goes to 1500ma. Very steady at those.
with the SGS3 charger that I had, it's a constant 900ma whether screen is on or off... (1.0 amp charger)
now I guess I will have to see if this is the case with any 2.1 amp charger, or if it's specific to samsung's charger with snapdragon's quick charge feature. I believe only certain chargers allow use of this.
I don't know, I'm getting 1800mA by using stock wall charger with USB3 cable and 450 with USB2 cable. I know GS3 would charge at faster rate when using original Samsung wall charger and cable, which had data lines shorted, not sure if it's the same with Note3.
I don't remember for sure, but I think charging rate from computer was pretty much the same 450mA regardless of USB3 or USB2 port or cable. I remember this because I was surprised they didn't take advantage of higher power ratings with USB3, but maybe it was just my particular setup. I used application that shows charging rate, so all is with phone on, but it makes perfect sense, about 2 hours from 0 to 100% charge, if you allow some extra time for trickle charge at the end, losses and usage.

You can't compare that app to a meter that shows you the actual current being drawn
Sent from my SAMSUNG-SM-N900A using Tapatalk
why not? How do you think your meter is working? Phone has similar IC. How did you come up with your numbers first of all? I thought you plug Kill a watt into outlet and it shows what the charger is using at 110v and at about 10 watts(or is it 220-240v for your location), your unit maybe at the limit of accuracy, since the amperage would be somewhere around 100mA, where your device is designed more for larger power consumption like fridge or TV running 300-1000watts and few amps. Is your unit somehow capable of measuring what the charger is outputting and if so, how?
BTW you can't get more than 900mA from PC even over USB3, thats the max limit.
I checked again: galaxy S3 wall charger is giving me 600mA, Note3 charger with USB2 cable gives me 1200mA and Note 3 charger with USB3 cable pumps out 1800mA, computer USB gives 450mA regardless of computer port, but there is something wrong with the USB3 cable that I got, is not connecting properly and I have to wiggle it to connect so maybe bad cable is the reason I don't get higher charge rate from PC USB3.
so i lost my fast charger which i didn't didn't use anyway as i kept fast charging unchecked in phone settings
now i got a new romoss charger which is a good charger AFAIK. it is rated at 2.1a, plugged it in and it took too long to charge. i downloaded an app called Ampere to measure the current and the maximum it gets is about 1000mA.
i thought the new charger was ****ty so i tried my friend's LG charger 1.8a and got the same results. tried another 2.1a samsung charger and nothing exceeds 1a.
is it something wrong with my phone or is it software related?
i'm using eRobot's newest rom with spaceX kernel (also tried googymax and suemax kernels). tried to check the fast charge option and again, same results.
any opinions or thoughts are much appeeciated
thanx
You need a Qualcomm Quick Charge 2.0 compatible charger in order utilize adaptive fast charging on your Note 4([email protected] & [email protected] output). Buy new Note4,Nexus 6,Motorola X Style charger. Also make sure your USB cable is undamaged/good quality, since not all cables actually support fast charging.
i dont need to use it as a fast charger, i just want it to charge with 5v 2a which the chareger is capable of
Are USB type C to USB A cables capable of fast charging? Or is USB type C to USB type C the only way of getting fast charging?
You can get somewhat fast charging on an A to C cable theoretically, up to 2.4A, however as USB Type A isn't rated at 3A you won't get the full speed of a true Type C fast charger. I found with many Type A 2.4A chargers though that none say fast charging, but that may just be because I'm using the cable that came with my 6P.
I bought this cable and plugged it into a USB 3.0 port on my pc. It delivers just as much juice as the stock charger. The two both charge at the same rate.
Updated. I'll add that USB 3.0 is capable of delivering up to 5 amps with the right cable.

I have the Play store Google cables and they won't rapid charge with my car rapid charger , but the Type-C to Type-C google cables will with same charger . So I'm thinking no but I don't have a AC rapid charger to confirm .

A USB 3.0 port on a PC can only deliver up to 900mAh. The stock charger is 3000mAh.

That is a big difference in mAh. It does rapid charge pretty fast though when plugged into my pc. It did not rapid charge with the cable Google provided though. I had to buy the joto which I showed above.

Does your phone say rapid charging? What does Ampere show as the rate of charge?
Before the car was broken into I had a Belkin 4 port charger and the A-C cord delivered fast charging just fine, the one it came with AND the third party cord I ended up using also, have a couple of Yoozon branded cords from Amazon
I have a-c cable, and tried charge it using a 2.0a power bank. It says charging rapidly. Is it save to charge this phone using power bank?

Yes. It says rapid charging. I'm not home now but will check what it says it charges at. I did grab a screen shot yesterday though. You can see by "USB debugging connected" that I am in fact plugged into my pc and it says rapid charging.
Connected to pc I get Max 1050 mAh. On stock charger I get 1850 mAh Max. So the stock charger will be about 40% quicker than USB 3.0. Guess one could just buy a USB C 3.1 pci card if they need it as fast as the stock charger

The stock charger is 3000mAh, so depending on how low your battery is (it charges at a higher amperage at a lower battery, and slower as it gets close to full), you would likely see 2500-3000mAh when charging a nearly empty battery, which would be 3x faster than a computer USB port. I'm not sure why it says charging rapidly though, that should only happen if it's above 2000mAh or so.

Maybe an extra pin being present tricks it(wild guess). I did notice the fluctuations in mAh and am glad to know that's normal . One thing I noticed in the app ampere is it said the port was capable of delivering 1800 so maybe it's just reporting wrong in marshmallow.
OK.... so i wanna know is it bad if i charge this phone with samsung adaptive charger ? and what about AUKEY USB-C Car Charger with 5V/3A USB C & Quick Charge 3.0?
My another problem is when i use oem charger my phone getting really hot like the back panel 110 degrees till almost 90% and then start cooling down, but i dont have this problem with samsung charger and my phone still charge pretty quick.
is anyone has the same situation?
The phone uses USB-C power delivery for charge spec. QC3 chargers don't work at all on my PH-1, seriously charges at .5amps. You're fine to use the Samsung charger or any other adaptive charger like Ankar power port chargers, they work fine.
Not sure about your phone getting hot using the stock charger though, mine doesn't do that.

So the phone will charge with an old USB Type-A charger and a Type-A to Type-C cable? What if it's not a QC3 charger like my Anker PowerDrive 2? I've read that some peoples phones charge slower than it uses power when using older chargers, but then some people say they charge ok, slower, but not that slow.

Yeah the power port chargers work just fine. Just not QC3 chargers, in my experience.
My Asus Zenfone Max Pro M1 is taking too long to charge. Earlier, when I started charging it, it would first show 'charging slowly', then 'charging' and then 'charging fast'. Now it is always charges slowly.
I searched around and followed the advice of trying another cable, but the problem persists, so it's not a problem with the cable, but with the stock charger. I borrowed a friend's Poco M2 Pro's charger. The specifications of that charger are:
Model MDY-11-EL
Input: 100-200V ~ 50/60 Hz ~ 0.5A
Output: 5V~3A / 9V~2A / 12 1.5A
Input: 200-240V ~ 50/60HZ ~ 0.6A
Output: 5V~3A / 9V~3A / 12V~2.25A / 20V~1.35A/11V~3A Max
The Asus stock charger is
Input: 100-240V ~ 50/60 Hz ~ 0.3A
Output: 5V~2A
When I used the Poco charger using the Poco charger but the Asus stock cable, the mobile started charging quickly, also showing 'charging fast'. This means the stock charger is damaged, and needs to be replaced.
From what I've understood, a fast charger doesn't make any difference as there are limits to what the mobile/battery can accept. Is the same true for the Max Pro M1 as well - meaning a fast charger can be used without any fast charging benefits (meaning same stock charging speed) BUT WITHOUT DAMAGING THE PHONE. This is the most important question I have.
Also, the Poco has a USB-C cable, so I removed that and attached my stock Asus cable to use it - is this okay, like any charger can be used with any cable, regardless of whether it is USB-C or not?
Since I have to buy a new charger, are there any you all would recommend. I've found a few:

I also have the charger of a Samsung Galaxy Tab A 10.1 Tablet:
Input: 100 - 240V ~ 50/60Hz ~ 0.3A
Output: 5.0V~1.55A
The output of this charger is lesser than the stock Asus one, so would using this one cause any damage to the phone?
Thanks.
Anything rated above 2A will work on this device.I suggest you buy the Ambrane AQC from the first link.I saw another member using it and the charging speed he was getting was pretty fast when compared to the stock charger.
I would suggest Oraimo (2nd option).. I've been using this charger for more than a year now.. Charging is fast and also charges 2 phones at the same time.. It gets hot while charging 2 phones but I have never faced any other issues yet..
