Ok, well...
I'm Korean, and I've searched almost every Korean tablet forums, yet can't find the reason :crying:
So I came to here, XDA.
The problem is, my Tab Pro 8.4 won't charge at all.
It's looks like an usual charging problem of Tab Pro 8.4, however, mine's little bit different.
With the charger plugged in and tablet is on, I can see the lighting shape on the battery icon at the status bar (which appears the charger is plugged in) ,
but no matter how long I charge the tablet, it's 0% and turn off after like...10 secs.
With the charger plugged in and tablet is off, I can see the battery pic appears on the middle of the black screen.
BUT, like the former situation, no matter how long I charge the tablet, I turn it on and it dies quickly.
SO, my problem is this, and i can't find a tiny reason why my tablet got (or how to fix) this battery problem.
Never seen a battery problem like I have right now.
I got several ideas about this. (Hope this will help you to fix my situation )
1. My tablet's rom is not pure. (But not rooted.)
As far as I remember, I applied the Ukrainian version about 3 weeks before.
Is it possible the this is the reason?
If so, wiping the original rom and applying the new one would help me?
2. Is it possible that the battery and the tablet connection got a problem?
If so, open it by myself and re-positioning the battery would help me?
3. The battery charger part might be damaged.
Then it leaves me the one option {GO TO THE SERVICE CENTER} ?
4. well...not 4.
have no idea.
Using same charger which is official SAMSUNG's.
I will keep monitoring this thread.
Little help to poor man would be really grateful, THX
PS
I just tested download mod.
With the charger is plugged in, it's working.
to see if the charger is bad, fully shut tablet down and then try to plug the tablet into a USB port on a computer and wait about 8 hours, then unplug it and see if the tablet holds any charge (battery might still be low but it should have enough charge to run awhile), if above works then it means you need another wall charger (5v 2.1A).
if it still just powers off or dies then it means the battery is bad or not connected or something else is wrong with it.
1. Try another USB cable
2. Try another 5v 2.1A wall charger
3. Try charging on a PC
4. replace battery.
To verify your tablet is charging, you need this little tool
http://www.ebay.com/sch/i.html?_fro...usb+power+current+and+voltage+tester&_sacat=0
Current should be 1.5 to 1.7 Amps, voltage should be 5 to 5.2 V
If the charging current is under 1.5 A, you should change different USB cable or adapter
If cable and adapter are fine, the next is charging port, it's easy to replace if your is defective.
Never use usb port on computer to charge, it only supply 0.5 A and your tablet needs at least 2 Amps for charging properly.
These are basic steps you need to do, without basic information I cannot tell what is wrong with your tablet: not charging or bad battery, or the worst: bad main board.
The one you have to verify: your tablet is drawing normal charging current around 1.5 to 1.7 Amps when plugged in. You can not troubleshoot problem just by guessing.
The most common problem of Samsung tablets are cracked Battery connector, a simple re-solder will fix the charging problem.
There are many unknowns, you have to eliminate charger, usb cable, usb charging port as the source of problem first. Then next look for battery or battery connector.
Otherwise, you will confuse yourself and others what causing the problem. Elimination is the key to figure out problem from many unknowns, one by one at a time. There's no short cut , otherwise, you can not figure out where the problem comes from.
I see many users send their tablets for service and the problem just comes from a bad cable because they have no idea what's wrong with their tablets.

You can charge from a computer fine just as long as the tablet is fully shutdown first (so you see the battery icon scrolling), this will ensure the 500ma will go directly to the battery and not running the tablet and os, it will charge very slowly but it will eventually reach 100% as nothing is drawing power from the battery to drain it (though I would only charge to 20%, to see if it holds a charge), however this method is just for diagnosing if the charger is bad and have no current alternatives, obviously this should not be a long term solution and never used when the tablet is running, but rather to see if the battery can hold any charge at all.
if you have another 5v 1+A charger laying around then use that instead., if the charger is the problem you can pick them up pretty cheap off ebay (make sure the hallmark icons and model number match to avoid knockoffs)

To see what is wrong with charging problem, you should never use wrong charger like 5V, 1 A or a USB port on computer. If using a 5V, 2A charger and a correct USB , any reading is under 1.5 A, there is something wrong with charger, or USB cable, or USB charging port, or battery connector. Even wrong USB cable, the one has only max of 1A, also is the source of slow charging.
His issue is not with slow charging, it was as soon as he unplugged it the tablet instantly powered off, in this case if the battery is 100% dead then damage is already done and once a lithium battery is completely discharged then most likely no charger whatever the mA is will bring it back...this is why I was saying to charge it from whatever source since you need to get a charge into the battery before it's irreversible damage.
However after re-reading ops post I think it's safe to rule out the charger as the problem because he said he could run the tablet with it plugged in (so that means the Charger is providing enough power to run the tablet) according to my mA reader this alone is around 500-700mA in standard use / full brightness
This also mean we can rule out a bad Micro USB port on the tablet since a broken one wouldn't allow power to the tablet.
the problem likely lies with a bad battery or a bad battery connection, the probably only option at this point would be for him to have samsung service it or take the chance to replace the battery.
(BTW I have all the tools nessasary and I know what can and can't charge this tablet)
Yes I know it needs a 2.1a charger to charge it while it's actively running since a good portion of that power will go into running the tablet and LCD if needed, it does not need a 2.1A charger when it is powered off and 500mA to 2.1mA will still charge it.
Three is a thread here talking about reseating the battery. Look it up. That may help.
Agree with otyg. I recently had a similar problem. My galaxy tab s 8.4 would power off immediately after being removed from power. It would register as having 100% charge while turned off, but once powered on, the tablet would show 4% charged or lower. Another thread on this site mentioned that the battery contacts on the motherboard have cracked for some owners creating symptoms like ours. I resolved the issue by applying a low resistance conductive adhesive to the cracked pins linking the battery to the motherboard. If this happens to be your problem be very careful because there are other contacts next to the battery pins. Good luck!

I have an untouched, unbranded Defy on 2.21 which works fine until I connect it to a usb lead for charging whereupon the touch screen stops responding and usually remains like this for about 30 seconds after I have unplugged the usb cable.
Until this morning when I had had it connected overnight to a cradle by the bed and could not turn the alarm off. I ended up pulling the battery, but at least I was awake by then, I suppose.
My question is: is this a common problem, and if so is there a cure?
And a supplementary one: would a custom ROM, CM7 or Miui, solve the problem?
Any help greatfully received!
my defy behaves exactly the oposite way. When connecting with USB cable I am able to ude the phone properly, everything works fine all applications' responsiveness are great. However, when charging the battery using the power cable, the phone starting hanging on every application. Everything starts getting slow and a simple touch takes 5 or 6 seconds to retrieve any action from the phone.
I dont know if this a common behavior for the defy neither if has any fix for that, i got used to it so i always charge my phone when it is off.
I have this issue too, but a little different. When I use a different charger than the original one, the screen is stuck, but I think, it is charging. When I use the standard charger, it works perfektly. I can't explain why.
By the way: I'm using CM7 with the nightly from yesterday
i am also using CM7, but the beta 6 version. I will try this test. I have two different charges, one original and another not, i will see if it behaves the same way you are saying. i will post my results soon.

same here..
Possibility of charger voltages rating differences giving out the output here I guess.
The original charger has been calibrated with just enough voltages/current to supply the phone during charging whilst the non-original charger doesn't have the exact voltage/current needed by the phone during charging thus giving the phone all sort of problems. One may see the non-original charger has label the right rating as per the original label but that doesn't give any warranty it work exactly like the original charger.
I recomend to use only original charger to avoid any damages may occur to the phone.
If one using original charger and still having phone behaving strangely. It may be caused by the phone itself(hardware issue) or the original charger(manufacturing defect) which by this mean you're one of the unlucky owner.... get a replacement ASAP..
I'm not sure about running firmware as such Eclair, Froyo or custom rom would do anything about charging side effect here.
I thought, that an intelligent power management only takes as much current as it needs. My adapter has 2 outputs (max 500mA, max 1000mA). I would expect the phone to work with any of these. When I plug in my navigation unit it works perfectly.
I'll take the adapter with me and try it with the original Defy of a friend. If it works with his phone its a software issue if not I'll have to look out for an alternative charging my phone in the car.
i deeply tested last night, charging with the original charges let the phone 100% useable without any lags while the usb charger kept me having lags and keeping the phone without any good responsiveness. No more usb chargers anymore
same here, original charger (btw, that is ALSO a USB charger...) works, but aftermarket charger, screen no (or little) response.
when connect to pc, works so-so.

don't expect every gadgets will work on any universal charger. The exact rating counts on a delicate devices specially on touch screen product. Grounding too must be equally the same from the charger to the phone which would result non side effect on using while charger is connected. Avoid using local based charger if possible as it could save your phone from damaging. Buy original if you really need it.

this happen to me too sometimes, but not all the time
Anyone else notice that our Nitro is rather fickle about the power source it receives?
If my battery is completely drained, it MUST be plugged into a higher power source than USB (so far a wall charger that ouputs 750ma works) until it gets an initial charge (usually needs at least a couple of %)...Then it will accept charging from USB (USB provides 500ma).
I can tell when it's in this "state" because it remains dead if I plug it into USB and then if I plug it into a wall charger the touch buttons at the bottom flash for a few times and then the LG logo pops up and finally a charging battery icon comes on. Considering this sequence, this seems like a functionality of the phone. I wonder if this is common, my Nexus One certainly didn't have a higher-initial charge rate requirement when the battery was dead.
I've experienceed the same scenario.

I only have chargers that operate 1.8amps and higher.
As the battery is an issue the higher the amps the faster it will charge

Well I did notice that if it was on usb...and I had bluetooth...gps, and wifi...plus running some apps and stuff...the battery actually continued to drain I think they have the usb thing as a safety measure...for some reason...I think it's odd...but meh
try a usb cable that has 2 jacks plugs to connect to tyhe computer. These cables are often supplied with external hard drives as they they require more power than can be supplied by just one usb connection.
I was also having the problem of my p-930 discharging while plugged into compute usb jack - even when screen off nad only in charge mode. I have since bought a dual plugged usb cable and it charges now. Although I haven't tried it from a completely discharged state.
my spectrum is the same way.. i can charge it with usb.. but it takes about 15-20 minutes to get enough charge to turn on

This! I only charge with a wall adapter now. I had a hard time charging it until someone here recommended this to me.
It is solved! Some 3rd-party usb chargers have same issue.
Samsung standard charger works very well.
I have a Galaxy Note 10.1 2014 edition (Hongkong, TGY).
Yesterday I updated my device to 4.4.2 (P605ZSUCNE3_P605OZSCNE3_TGY) with Odin.
Upgrading was OK, everything works fine except a battery charging problem.
When device connects to a usb charger, the battery stops charging after 1-2 minutes although not 100%.
I tried something but nothing helps.
- Changing charger/cable to another
- Factory reset (Recovery mode)
- Flashing P605XXUCNE2_P605OXACNE2_NEE (Nordic) Firmware
- Power off mode charging -> It works. This is the only way to make device 100% that I found.

I've got the same issue following the 4.4.2 update, all my third party charges that worked fine before the update no longer work. Battery management software show the device getting the same mA of current to the battery but the device is not charging (it says that it is!).
Original charger does work but is not a valid solution for me, why are the non-oem chargers not working all of a sudden and how do I get them to work again?

I'm having the same problem, trying to fix with some charger mods (shorting data pins of USB) or fast charge kernel. The kernel hack did not work yet, but shorting the d+ and d+ pins of usb cable on device end works. (although I could achive max 1.5mah)
According to this
http://www.androidpolice.com/2014/0...t-on-the-note-3-but-there-is-a-root-solution/
Samsung denies any intentional blocking and a connection between KitKat and third party accessories.
I tried my third party chargers and they too didn't work. Charging stopped when the screen turned off. However, my Motorola and HTC chargers do work. Maybe the third party tings have inconsisten voltage output or something like that.
I had the new Tab s 10.5 and some of my usb chargers would not work. I found a deal way to good to pass up so I returned the Tab s and THOUGHT I was getting a Note 10.1 2014 wifi. Yet lol I didnt I got a 605 which is AWESOME ..I just always wanted the SnapDragon chip. It was a tad over $400 32gb NEW.
Anyway so I turn it on set it up and it was downloading 4.4 already I wanted to stay with 4.3 after reading around here. Yet so far it works flawless. All my usb chargers work. I can be doing ANYTHING and it keeps charging. Like I said the Tab s I could ONLY use Samsungs.
In my case Android 4.4 for P605 is way better than 4.3. Great battery live, great performance, no or very small lags. But I had initial release of 4.3 ROM which was never updated.
I have a third party charger and it goes well. It is Chinese no marks.
If it is just shorting the data pins, then it will charge. But you will be limited to 1500mah.
I think it needs an Apple compatible charger. Only the Apple standard supports charging over Usb 2 at 2A, for the Ipad.
The Anker 5 port 8A charger is fantastic.

No, I did that mistake and bought a dual port 4a charger. Samsung somehow detects Apple charger and stops charging when screen turns off. I had to make an adapter for shorting data pins, like this, I can at least charge with 1.5a
while i was on vacation my p605 starts having the same problem. It is just loading while the screen is on. After getting black/off it takes a few more seconds till charging stops. This problem is accompanied by the symptom that the tablet won't be recognized by the pc anymore. It is just loading ('til the screen gets black). i have no idea what to do. i am not sure, if the different voltage on vacation could be a reason. based on the fact that i can't get it back to stock, i guess i can not get it repaired by warranty (or is there any way to get it stock? unfortunately mobile odin is not supported). i would be glad about some good hints and thank you in advance
Your cable or charger might have a problem or you may be using a different charger than original one.
Hi everyone,
I've found a bit different issue - my P605 (LTE) does not want to be charged when plugged into USB port (so, no charger is being used).
I tried both using laptop and stationary PC
//ok, nevermind. I've just found somewhere else, that it has been always like that (not noticed that before)
Exact same problem here - charging stops as soon as the screen lock kicks in, even with the original Samsung charger. Brought the tablet back to the tmobile store and had them connect to another Samsung charger - still happens.
Has anyone found a fix for this short of shorting the harger pins?
I don't follow my own advice, and never had this problem. But charge with the original cable where the two GND pins are connected. In most cables one of them is open.
My old Garmin Street Pilot with mini usb used the second GND pin to determine whether to remain operational and charge, or go into pc connectivity mode and do nothing else.
I have the same problem . After upgrading to Kit kat just a few days ago it would stop charging moments after the screen turns off. No matter what cable or charger
This happens to me only when I'm not using original 5.3v charger and original cable. Check your cable and charger. (although I think it works with 5v Samsung charger of my note 3 as well)
My last charger had 4.9v with no load, and certainly lower with a 2A load. No Problems. But if a charger is badly stabilized, it may drop too much, and the Note is very demanding, with twice the current of a typical phone.
I had a DIY adapter to charge my old Nokia stuff via USB. The Nokia chargers have a 5v spec, but one provided 6v, another 7v. And USB voltage seemed too low, there was sort of sporadic charge, with the connection dropping after a short time. But all connections were fine, must have been a voltage thang.
So i still have to keep a Nokia charger ready, only to charge my Nokia BT headset.
Galaxy Note 10.1 2014 Edition Charging Fail
Has anyone discovered a fix for this:
When I plug in my tablet...Samsung Galaxy Note 2014 Edition...Using any plug (I have tried factory charger, and multiple alternatives including Ipad Charging adapters) when the screen is on the charging occurs, but When the screen closes about 2 seconds later the screen turns back on the way it does when charge is complete, only its still at same battery level as before! I have tried closing all apps and still the same, Used Task Manager to close all apps and clear the RAM and still nothing, Gone into app manager and closed running processes and still the same results! I am operating KitKat (OS since purchase) and the only actual way to charge it is to leave a plug in all day with the screen On, or shut off the Tablet!
Is there a fix for this or what?
Its bad enough that I cant find a good bluetooth keyboard that is compatible with this tablet! Im on the verge of trading it in and going Apple! Someone please help...Keep me from turning to Apple!
Is there a fix for this even if it requires manually adjusting chargers or the tablet itself (the internal components)?
thank you all for your help!

Recently I experienced (again) charging problems with my Nexus 7 (2013). Usually they first slow down the charging process, and after some time the tablet even does not see the connected wire anymore. Which is strange (Xperia Arc S still sees it, and is charged at full speed), but that could be due to worn-out contacts, and can be solved by using a new cable.
Recently the charging stopped completely, and even a new cable did not solve the issue, unless pressed with a certain pressure and direction into the USB port, which starts a slow charging. This was tested with three different chargers and four different cables, partly used, partly new.
In order to find the problem (worn-out USB port anyone?) I opened the back cover, and measured the voltage at different places while "charging". The tablet itself tells me that it does not charge, but I measured 5V on the respective pins at the PCB in the inside of the Nexus, and I measured 4V at the connections to the battery. Why does the Nexus still tell me that it does not charge? Apparently the battery gets power, thus the USB port is not faulty.
After my last tablet died from this very problem, I resolved to avoid it with my next one. That's one of the reasons I specifically chose the Nexus 7 2013 as my next tablet: IT SUPPORTS WIRELESS CHARGING!
So, I bought a QI charger along with the tablet. That USB port is going to remain as pristine as possible. You may be able to get around your current situation by doing the same thing.

This is inconclusive. If you measure the battery without USB power, 4V will be still there.
Get one of these to check power supply current draw.
Hi,
Have searched this forum and other sources on the web. Can't resolve my issue. Hope I can get some help.
Running the most recent stock update. This is a Wi-Fi model only.
I will explain what happened.
Had the tablet plugged into outlet.
Had the Chrome browser open, was logged into a NHRA drag racing website and watching live racing.
Was Chromecasting to my 55" Sony tv.
The tablet was in this configuration for about 4 hours, the screen went black and lost Chromecast connection to tv.
Could not see if the battery was running low, as the tablet was at full screen.
Left the tablet charging in a different outlet. And with different cables.
Have tried all the Power, Volume and Home button combinations.
Have had the back cover off. Disconnected the various battery cables. Took the battery completely out.
No response from the tablet. No vibrations or flashes.
Am I missing any other solutions.
Thanks in advance.
does it attempt to charge?

Yes. The charger gets warm. Took back off, and checked with multimeter. 4.09 volts and 3.44 amps.
Going to order a replacement battery. Though I don't think the battery is bad. I think something has to be reset on the Tab S.
Thanks.
Don’t fix problem by guessing. Search eBay for USB voltage tester, it will display the voltage and charging current. You can verify the problem from usb cable, charger, USB port , battery connectors or main board .
The most common mistake is assuming the battery is bad without checking other parts feed the current to battery.
If your tablets works, the charging current should be around 1.5 to 1.7 Amps, more or less depending the battery status, less than 1.5 amps when it’s nearly full.

These measurements won't give you any glue what is wrong along the charging circuit which involves many parts.
Use the USB voltage amperage tester when charging, it will tell you how much charging current is drawing.
If it's less than 1.5 Amps, then using elimination method to find where is the defective part. You must have known working parts for testing.
Start from USB cable, charger, USB charging port, then battery connectors: this one requires technical experiences to see what is wrong. Most average users don't see the cracked solder joints on battery connector which requires microscope. With the naked eyes most won't see anything wrong because the crack in underneath of solder joints
From my experiences, changing the USB port won't see any differences, then problem is mostly from battery connectors. The one from mainboard needs to be resoldered, the one from battery needs to fix the cable clips. I have been fixed hundreds of them, so this is not an opinion.
