Charging current - Galaxy Note 3 Q&A, Help & Troubleshooting

I have 2 device note II and note 3.
But my note II have larger charging current than my note 3.
Note II 1800mA vs Note 3 1200mA
Note 3 have larger battery capacity, so why have smaller charging current?
Is it normal or my note 3 usb cable need to replace?

Charging power is controlled by the Controller. Depending on charging level, and maybe other things.
If your screen is on and maybe at high brightness, the Charging power is up to 1200 mA.
Switch Screen of or reduce the brightness and test it for a longer time, it should charge at 1800.
Let your Charging Power Test App run and wait more time, then check again.

I always use low brightness on both device.
And I already test my note II even when i run a game charging current constanly shown 1800mA

You can't compare the both devices!
Both Charger have 2 A. Okay!
But...
Note 3 needs more power if it's on, because....
Bigger Display
Full HD
Bigger CPU
......
all needs power and the rest is for charging the battery ☺
I'm not a Samsung technical!
But in my car it's the same.
If you drive with all electronic equipment on (AC full, lights, seat heating, Window and mirror heating,......) the Battery will charge at lower power from the alternator.

battery takes a little more time after 100% make sure to charge it till its full.
But if it gets to 99% when your phone is in use then its normal.

Try to recharge it till 100% unplug the usb charger then plug it again do it 3 to 5 times you should be fine after that.

It seems to be normal. If have 2 x Note 3 a have same. I talked to Samsung and get a new Battery, but the same.
This will work :

Directly after unplugged (after Message BATTERY FULLY CHARGED) Then unplug and directly plug in again, wait for Message BATTERY FULLY CHARGED.... and again and again
But....if it works....one or few days later you will have the same issue again [emoji16]
I ignore it after Samsung changed my Battery

No, I don't think that is a battery problem. Maybe a Software Problem in the Charging electronic or just a wrong information.

charge until 100%, unplug your phone, switch it off, plug the charger and charge for 5 to 10 minutes. Unplug the charger, turn the phone on, plug the charger back for another 5 to 10 minutes.
Actually, guys, the reason for this is completely different.
Modern smartphone charging works like this - the battery is charged at high rate until 80-90%. At that point, the charging rate (how much current is directed to battery) is decreased to avoid overcharging. When battery is fully charged, the charging process is stopped until the battery level drops to about 95%. Then charging process is restarted.
The lowered percentage happens if you unplug during the so-called pause in charging. Android itself may still show 100% in the first place, but then shortly after decreases to the real amount. It is just the way modern batteries are built and there is no way to fix it.
Besides, does the 2-3% of battery really matter that much?

Charge Battery faster - Snapdragon Quick Charge 1.0

Hello,
i want to know if our Z supoorts the Quick Charge 1.0 technology. Because I hate it to wait about 3 hours before my Z is full. Actually im using a 2A Charger by Samsung, but it isn't really faster than the orginal charger? Has our phone a Charge Limit at 1.5 A?

If you want something like that so you need custom kernel that support it. But if you fast charge the phone it will fast drain too!:silly:

Use the default or original charger that came with the phone, not samsung's.. Then your phone will charge faster.. Mine takes like 1 and half hr to get to 5-80% and then another hour max to get to 100%.. I have seen the actual time it takes to go to 100%.. Its like 2.15-2.30 hrs.. Its never crossed 2.30 hrs..
using charging dock: from 30% to 100% - 71-75min
using microUSB: from 30% to 100% - 77-80min
using car charger: from 30% to 100% - 75-90min
using my old LG charger: from 30% to 100% - 70-75min
I set low battery power saving in stamina to 30% so i always charge it when it turn off all options. I dont use my phone in this time so screen/wifi is off, I have only one app in white list in stamina mode and LTE/NFC turned on all the time.(stock 4.3 ROM)
so its really weird that you need to wait 3h to charge your phone... maybe something is "sucking" your battery?
Maybe you have low network coverage? and phone use loots of energy to maintain network?

Adaptive Fast Charger

Hi guys! I just bought a Note 4 a couple weeks ago and I was wondering if the Adaptive Fast Charger would work on the Note 2014. Haven't tried it yet but I was curious as to whether anyone else has.
Thanks!

I own both devices (Note 4 + Note 10.1 2014) and can confirm, that the charger works but not in "fast charge" mode.
Unfortinately the 10.1 charges quite slowly to put it politely. I was hoping that it would at least be slightly faster, although it should be because even on the low power mode, the new base has a slightly higher output.
I also have the Note 4 and Note 10.1 (2014 edition). I can confirm that fast charging doesn't work. Maybe someone knows but I thought an earlier version of Android had the option to turn on fast changing. I assume that it's a function that needs to be implemented at the kernel level.

How could you tell if it in fast charge mode or not?

Well, first of all, it does not charge any faster then normal, at least not significantly enough for me to notice. I have to admit, I did not a test with a stop watch.
The second thing is that when you connect the fast charger to the Note 4, there is a fast charge notification shown in the status bar for a view seconds. This is not the case for the Note 10.1 (2014).
From what I remember with my Asus Transformer Infinity fast charge could be be turned on using Trickster Mod. The kernal has to support it of course.
The Asus units use 15v for charging. If you somehow can trigger this mode on the charger, which someone succeded to with his Iphone, the Note's voltage regulator just will transform 15 instead of 5 volts down to 3.7v, the excess energy will be transforned into heat, and the regulator may fail.
I have a Note 10.1. I just charged it in lightning fast time to full charge. I used it for about 20 minutes. Then the indicator dropped to half and now it indicates dead after a very short period of time. Not sure if the battery is fried or if the software is freaking out. Ive been having charging problems before. Attempting to charge enough to do a factory reset to see if that solves the charging problem. If not - battery replacement.
I never had to cope with a lithium battery, which lost much of its capacity. But with most battery types a huge loss of capacity means that the battery charges from empty to full in no time, and back to zero in no time during use. The voltage range stays normal, thus the battery level should also reach up to 100%, which equals 4,0 to 4,2v in this case.
A battery seemingly no longer reaching full charge is a problem with the Android Coulometer. There are apps which seem to be able to fix this bug.
A similar, more popular Coulometer bug are battery level fluctuations. These aren't that simple to fix, probably only factory reset or the unbricking procedure help. But this bug is self-healing over a LONG time. We're talking bout months.
Thought you might like to know, the original Samsung charger works well, but to achieve maximum results you need to use a 2.5 Amp USB charger. This used to be stated in the Samsung+ app. This almost doubled the speed of charging the tablet. I know that this isn't quick charging, but it's worth knowing.

How long does your s8 take to charge full from around 5%?

I have the feeling my s8 doesnt really fast recharge even if it's enabled (i'm on 2nd charge now)... how long does it usually take you guys to charge it full when its very low, around 5%? And how long does it say it takes on the notification? Thanks!
About 1h50 or something with normal charge, not fast charge.

Mine definately took longer to charge than that the 2nd time (the first one i was asleep so i dont know) and with fast charge. Does it matter which side you plug in the cable or it's the same? I'm getting worried.
The side of the cable does not matter. I normally charge my phone when it's about 15% and with normal charge it takes around 1h40. Next time I charge it around 5% I will check but I think it's about 1h50 to 2h. My S7 was definitely faster in charging.
Takes about 90 minutes with fast charge
Around an hour and 20-30 minutes, a bit slower when I'm using wireless fast charging.
Did you notice a substantial difference between normal charge and fast charge? Lat time I checked it was about 10 minutes difference until full charge. I expected more, it was much better on the S7.
I think that fast charging got capped by samsung after all the note 7 exploding battery horror stories. And it got capped at 2.45amp fast wired charging and around 1.35 with fast wireless charging since the nougat update on the galaxy s7. when it was around 2.8 fast wired and 1.8 fast wireless charging on MM
Beside the charging rate cap, the fone is much cooler while fast charging now as it used to get crazy hot reaching temps above 42c while now it never gets over 36.smthing.
So while its slower i guess its a much better bet for the battery health and your safety.
Normal wired charging didnt change between MM and nougat and its around 1.7~1.8amp
These are my findings using the s7 and s8 exynos international versions and the statments above are purely my own opinion and experience which could be different for everyone.
I noticed that mine never goes over 1060ma while charging using Ampere. It takes about 1 hour 40 minutes to "fast charge" but it is cooler than any other phone I've ever had while charging.
The sad thing is that it REALLY takes longer if you are using the phone, like barely increasing its %. I even tried changing cables, chargers and places but now I know I'm not alone and this is how it works.
I have an Exynos.

IMO ampere is crap and slow to report, you need an app that can report as fast as cpufloat. As once you turn on the screen the charging rate will default to ~1amp regardless of the charging mode your using and thats when ampere starts to measure.
Use cpu float for info at glance
Or
Use accubattery to even help you distnguish which charging cables your using gives you the best charging rate.
Hope this helps

Back when I had my Galaxy S4 I used "CurrentWidget: Battery" which was really nice but is not working anymore so I installed Ampere.
I just tried both apps you mentioned and both gave me the 1050am right away. I'll try later on since I was at 90% and if I remember thats the point where it starts to throttle down the current.
I like the AccuBattery 80% cycle though, not sure I can really use it since I prefer to go with a full battery for the entire day.
Thank you!
Mine takes around 1hr 30 mins , The other night i turned fast charge off as i was going to leave it charge throughout the night but i actually forgot i had turned it off and had been charging for a few days with fast charge off..... surprisingly i noticed no difference! It still took around the same time to charge haha

You hit it on the nose. They slowed it to avoid the whole exploding battery problems just to play it safe. Also why they didn't cram a bigger battery inside it to keep heat down.
They lost a lot of money because of that. The only thing that really saved them was that some iPhones were blowing up too

Takes around 1 h 40 mins for a full charge. This is using the Fast Charger that comes in the box.

Bear in mind that the charging rate will default to 1050ma whenever the screen is turned on no matter what charging mode your using.
To use my method in cpufloat app, open the app n keep it floating on your screen. Turn of the screen for awhile ( lets say 5 seconds) and n turn the screen back on. You will have a split second to read the current before it updates to the 1050ma. ( you can slow the update rate in the app settings btw.
Accubattery will have 2 readings, charging rate when screen on, charging rate with screen off.

Yup, I noticed that, thanks!
Accbattery showed me a maximum of 1156ma obviously it was charging with the screen off. From there my test starts since this charge was done using a multi-usb charger and had something else charging and wasn't using the original cable. We will see
Thanks once again!

What other difference you want?
The charging issues on the Galaxy S8 seem to be widespread. I was hoping the most recent software update would help resolve these issues but it hasn't. Extremely slow charging (71% charged, 3 hrs 17 mins to 100%) and random connectivity (wireless charging paused) with Samsung's OEM wireless charger. What I've found with respect to the wireless issue, if I leave the phone on the charging pad after a few minutes it will eventually engage to a slow charge mode. Direct charging with the Samsung 2.0 Adaptive makes no difference, still a very slow charge. The normal Fast Charge Notification which should appear at the bottom of the display has never appeared and the tab remains grey in the Advanced Battery Settings even when enabled. Prior to purchasing the phone I had read and was advised by a Samsung tech the phone was suited to accept Qualcomm's 4+ Quick Charge. That seems unlikely at this point. Just got off a live chat with Samsung Support, not surprising the tech offered no solutions which I hadn't already experimented with. Booting up in Safe Mode to see if the app(s) were the problem, clearing system cache, app cache, using a variety of adaptives and cables, updating software, checking the C jack for connectivity. The S7 Edge I had previous to the S8+ was a great phone, no problems whatsoever. I honestly feel that Samsung is dragging their feet and haven't yet gotten their hands around these issues. Seriously, do they really want to experience another wide ranging battery concern? I think not. I can get a refund or replace the S8+ (SM-G955FD) but I'm wondering if the problems may be so widespread it could easily be an issue with the replacement phone. From the research I've done these issues are popping up on all models, regardless of the manufactures location.

why it only shows 1200mA charging?

hi, maybe is a stupid thing but i wonder why it happens.
i like to control how my charge cables are working using an app called galaxy charging current.
the point is that using a few 2A cables it only shows 1200mA charging.
i use the same cables in note2 and shows 1800mA as always
why? may it be a problem from the app?
is my phone not charging right? i have the option for fast charging enabled and using the 2A original charger from note 2.
i dont know may apps that tells you that charge detaill, almost that you can nearly trust...
thanks!
i forgot to say, i have the n910c model
If I had to guess, I'd say that both readings are correct. Your Note 2 reports the current as 1.8A because that's what it's getting from the charger, and due to hardware changes the Note 4 reports 1.2A because that's what's actually going into the battery (1800mA minus 600mA for the AMOLED display and other power-hungry components). Just a guess though, but this was the case with my Note 3.
