Hello, I'm a N8000 user. I'm facing a problem with my charging issue where my tab take a long time to charge and it takes 10 hours to get from 0-60 %. FYI, I'm using a custom rom CM 10.2. What is the main cause with the charging issue? Does it related with charging port, battery or charger itself? please help me. I'm stuck now.

Charger maybe, but most on here get a new factory cabel and that takes care of it.

Many similar thread already here & also the solutions.
But let me answer anyway.
Charging problem occurs because of one or more things:
Broken Cable
Broken Charger
Incompatible Cable
Incompatible Charger
Broken Outlet
Broken Charging Port
Broken Battery
To properly charging a N80XX we need a charger & cable that can deliver 2.1A, 5V of electrical current & voltage.
The factory default/initial charger & cable designed to deliver these requirements.
Using custom/cheap cable or cable extension can cause charging problem as it wasn't designed to deliver the required current & voltage.
Most custom cables & chargers on the market designed only to deliver 500mA(0.5A) - 1A, 5V.
Broken cable/charger can also cause it to fail in delivering 2.1A, 5V to the device.
Try another original cable/charger combination to test if one of them or both are broken.
Also try another electrical wall outlet to see if the outlet is the culprit.
For Broken Charging Port, you can change it yourself by buying the spare part & replace the broken one, but it requires high technical skills.
One mistake can cause you to ditch your device.
It's safer if you send it to a qualified/authorized service center or if it's still under warranty you can send it back to samsung.
The last possibility is extremely rare.
Broken Battery symptoms are usually different than your problem symptoms.
If the battery is broken, usually the battery life is shorter than usual and may be won't charge at all or charging time is very short.
But if this is your problem, you can't sent it back to samsung - unless the battery is factory damaged -, as you need to change the internal battery.
Try to find out which one is your real problem & fix it
REMINDER:
2.1A is producing heat so much that hurt your skin if you touch the metal part of the cable heads directly right after a long period of charging.
The heat it produce is much more intense than if you are using 500mA or 1A charger.
Poorly designed custom cable/charger can be melted by the heat & may cause explosion!!
...and.....ALWAYS SEARCH BEFORE ASKING!!
I hope this will help
I'd like to add that I was facing similar problem.
In my case, the problem was a stock charger cable.
It was not "broken" (in the meaning of totally cracked or cut cable) but it seemed that it isn't providing a stable voltage. In result, I was able to load the battery only when not using the device (plus the process was as slow as hell), coz when using it, the consumed power was higher than provided by the charger.
Meanwhile, before the problem occured, I was testing other solutions to be able to make charging cord longer than provided stock, which is only 1m. Those tests included using of the additional 2m USB-USB expansion cable which I was plugging to the plastic charger element from the one side and to the regular charging cable at the second side. Such a combination resulted in similiar results as above - then, it became obvious for me that the tablet consumes or wants to consume so high power that low-quality USB cable can't handle, and - especially if it is 2m long - it's degrading onto his way to the tablet.
Then, I am not sure if n8000, by demanding so much power, is not degrading the cable (even stock one) itself. I must say, that after that, I was using another charger cables (n8000 dedicated, one 2m second one 1.5m, both not original) which started to work significantly worse in even shorter time such as two weeks after first use. I am not a electrician or hardware specialist, I dunno if it is possible to degenerate the usb cable with the voltage such as one needed for charging the tablet, but during my over 10 years of passion within mobile devices, I have killed no more than 2 chargers IN TOTAL. N8000 killed 3 charging cables within 8 months.
For some time, I use another combination - I use a 1,5 long A/C extension cord, with a handy "8" plug at the second end. This fits into the charger "central box" after you dissolve it into two parts. Now, the voltage will not degenerate onto this 1.5m distance, as the cable of that type was designed particularly for 230V transfers, but it will still be perfectly mobile. At the second side of the box, I do not plug back the 1m stock cable (or longer not-official ones), but a cable that the Samsung provided along with an external battery, which is possible to buy here and there... It is about... 20 cm long The purpose of this was to avoid the energy lossess that occured when using longer cables and preserve the maximum possible charging rate. Since then (and about 5 months has passed) I have no further problems with charging, and the battery life seems to be much more better than I supposed it to be after over a year of really extensive usage (the only issue of above solution is that the plastic box in the middle is making really really hot, but it is not a critical problem i suppose, as since 5 months it HASN'T melted, exploded or something )
hay....i have the same problem but this tablet doesnt get charging
i think its not about charger because it gives 5v and 2A after the usb flat but in battery connector i got no current and there is just less than 1V voltage
So I bought a cheap cable from eBay that converts microusb to the proprietary Galaxy connector on this device. Tried to charge the device but it entered a bootloop. Unplugged the cable and tried charging with the stock cable and left it overnight. Woke up and the device was completely dead.
Wouldn't boot at all.
Tore it open, unplugged the battery and plugged it back in. It booted! BUT the battery was critical and it shut off immediately. Tried charging again, no dice.
So I unplugged the battery and applied 4v to get some charge into it. Got the battery up to about 3.6V, booted again and it showed 3%. So in the time I had with the device turned on I tried both cables again but neither would charge the device. I used a multimeter to test the stock cable and it was all good, I even did a beep test between the 4 USB pins in the stock cable and the places they're wired up to inside the note and everything was fine so it's most likely not the cable.
Anyway the 3% is long gone now and I can't boot or charge. The device and battery are fine and definitely working, it just won't charge through USB no matter what. I've tried different power points, different adapters including stock and normal usb ports.
I've also cleaned both the plug and the jack with a toothbrush.
Could it be that the internal charging circuitry got fried when I tried the dodgy cable? If so, is there any way to fix/bypass this?
I'm at a complete loss so any help would be greatly appreciated.
Regards,
Nas.
I would not recommend to charge battery directly outside the device or even remove the battery at all.
First you gotta make sure your cables are capable of charge other galaxy devices if a friend has Tab 7 or Tab 10.1 or other note 10.1 or another try your cables to see if they really work.
Because it may just be your cable, remember batteries have their own circuits boards of sort and batteries are sometimes picky on how they are charge especially OEM batteries that are not suppose to ever be out of the device unless are change for a new one in a repair.
So first of all cable check it a must, again is not as simple as check if all the pins works as this is not a simple USB (Universal Serial Bus) port is a proprietary port and cable, check the port in the tablet too.
As well it may be just a defective battery or worst case even a board problem.
Unfortunately I have no other device to test it with. I might just buy another cable and see how I go.
I know about the circuits on the battery, but I always thought they were just there as a safety measure due to the potentially volatile nature of Li-Ion when it drops below a certain voltage. I'll probably take your advice and stay away from charging it externally, I only did it once to see if the tab died or it was just a dead battery. The voltage never dropped low enough to trigger the circuit to 'kill' it, evidenced by the fact that I could get it back up to 3% just applying a constant voltage.
I'm guessing you've hit it on the head with the last sentence, might be a board problem which would be quite sad. Silly reason for a great device to die.
Thanks a lot for the reply, I'll update this thread once I try an alternative cable for future reference.
Ok, So to update:
I've bought and tested 3 separate cables, all provide 4.99V inside the device, but none of this makes it to the battery so I'm fairly certain it's the charging IC that's dead.
I bought a new battery that was charged to 40% so I was able to flash the device to see if it was maybe the custom kernel messing something up. Flashed to stock via Odin, still not charging.
From what I've read, I need a cell balancing circuit (since the battery is 2-cell Li-Ion) and a charging IC. I've found a suitable IC for fairly cheap, but I'm not sure if the balancing circuit is necessary. The battery already has one of these inside, but I'm not sure if this is just for Voltage/Current protection or if it also balances.

title should read: galaxy note 10.1 losing battery while charging
------
I got a galaxy note 10.1 this past January(purchased new in box). It has been working fine up until today. When its plugged in now, it shows the indicator that its plugged in/charging... but the battery drains.
I tried cleaning the USB port with a brush & even used a q-tip with a dash of alcohol(no luck). I then decided to do a factory reset & wiped the cache. Afterwards, it started charging properly again. At least, it did once... now its not charging again.
So to clarify, it was purchased brand new less then 3 months ago & am using the included(stock) charger. Tablet is not rooted either.
Anyone know how to fix this?
Are you also using the supplied cable? I have found some third-party cables only allow a very slow charge even with stock charger. As the cable can make a difference, it may be you just have a fault with the cable.
There are several reason that causing charging problem:
Broken Cable
Broken Charger
Wattage usage is larger than wattage charging
Broken charging port
Broken battery (rare)
Check which one is your problem
Use Battery Monitor Widget to monitor Wattage / Amperage.
Usually correct Amperage is around 1000 - 1600 mAh (factory Cable+charger)
It depends on usage.
I'm using both the cable and wall adapter/charger that came with the Note.
I did notice that the wall adapter that came with my Galaxy Tab 3 7.0 is also 2A 5W so I give it a try for the heck of it. Still no luck.
I could disassemble the Note no problem, would just suck if I had to buy a new battery as they're $70.
when i connect the cable every 1 min it stop charge and back charge again and in fact the battery is discharging if it was 55% it become 53% this when i disabled the fast charging in setting after android 6.0 marshmallow and when enable it device get hot very fast i could smell the heat easly? how to solve that
Sounds like a defective charger/USB cable/power source. In regards to it discharging and whatnot. Try with a different cable/charger/power source.
The heat is normal when you use Fast Charging, I thought everyone would've known this by 2016.
I use my phone's charger with a Sony USB cable. Because it has five pins on the inside, charges even faster than the four pins on my S6's OEM USB cable (and obviously more heat), the Indian version of the cable from Samsung has only four pins, they pulled one out, presumably thanks to idiots complaining about the heat.
Hi all,
I'm new to Samsung, with S8+ EMEA version (non-Qualcomm CPU) for ~3 months now.
This is after ~10 year with HTC while the last unit (up until 3 months ago) was the M9.
Using the same good quick car charger (compatible QC2.0) and different (original) cable I gets much slower charging with the S8+ vs. the HTC.
The scenario is the same in terms of applications and usage and both units confirm this is a "Quick charge" but the S8+ is raising in ~1% per 10 minutes while HTC did ~1% per 2 minutes.
Both were in the same light conditions, same battery temperature and such so I really wonder what the source is.
The S8+ will be fast charging indeed if stays unused in the same charger...
Thanks,
Oren
Just a guess, I believe it's heat management. Quick Change will slow down if the phone/battery is getting too hot to protect the battery. Mine behaves the same, it does not charge quick at all when I have Waze running.

Thanks for the reply, but as I wrote earlier, I'm aware of this and there is no temperature issues while I'm checking.
Battery is in the level of 30c and less.

Got the same problem . In my case was the cable and the charger I use before aukey quick charge 2.0 .it was a faulty cable solved. Go on playstore and search for ampere application check there how much you have and report back here we can compare to see if you got a faulty charger or USB cable

I'm also with Aukey quick charge 2 and the original Samsung USB cable but.
The fact is that it does indicate it's fast charging on the notifications bar.
Also, if it's closed, it does charge fast so cable and charger are fine.
The problem is somehow with the charging control while it's being used with Waze, for example, then the HTC was progressing in the charge while Samsung doesn't much proceed...

I done this yesterday . I bought also the bk disabler package for 1.99£ from app store and I can ensure you that the charging is so fast now
I am not make advertising or sell something I just wanted to help you. Yesterday got 6.30 hours screen on time and the charging time decreased
https://youtu.be/Y9GX88jFIE0
My conclusion is that probably the large screen with the high brightness in daylight is the reason for the slow charge.
Usually, during night time, the same charger, cable and applications will result in much better charging progress.
Again, temperature is not a factor as I do cool it if needed and check the battery temporary to assure it is cool.

So I try sorted this about 4 months.
Original cable and adapter and another 2 non original and all time same results. Nowhere it's say nothing about charging. Samsung block proper charging when is display on. I was ask them in chat they told me advice " turn off display when is charging" that is great advice when you need Nav and charging phone.
So I went to Samsung repair centre and they check phone and say all is fine so I told them my problem and they say unofficialy Samsung got some security advise when is charging and display isn't off that charging didn't work not like fast either slow charging is just keep alive.
Google new pixel have temperature block and LG have same thing like Samsung.
I know fast charging will problem with that big display and when will on. Ok but why didn't charge like slow charging. I not need phone charge in 1.5 hours but when I charging 5 hours and got +20% that is Bull****. Then come message " charging was stop then will cool down."
That is full of the Internet now. Many people has same problem.
I'm just interest if another companys Nokia one+ or HTC huawei xiaomi etc has same problem

I still believe it's related to the Note 7 issues, they are more aggressive about keeping the phone battery cool when charging. Just speculation on my part but it kinda makes sense.
As I mentioned before, with htc m9 charging was faster, it is also QC2 qualified phone.
And again, my battery temperature is low, it's against the air conditioning specifically for that purpose.

I think that what you will find is that the phone doesn't go above about 1.5A when the screen is on to keep the phone cool and protect against note 7 issues. I find my phone charges fast enough on Waze with a qc2.0 charger
Is there any solution for this issue? Can root app do something about it?
