[Q] Battery charged 10% in 2 hours - Sprint Samsung Galaxy S III

My original phone had problems with charging (it wouldn't charge at all) so I decided to bring it to the nearest Sprint store only for them to decide that the best course of action is to replace the phone with a refurbished one (and so I did).
Now, this new phone has shown a couple of horrible results:
The phone does not charge unless left alone. (Meaning it would not charge when I use it whilst plugged in; in fact it drains about 1% per 10 minutes!)
When it charges (while left alone) it charges UBER slow, it charged up 10% in 2hours prior to posting this forum topic
- EDIT: as of now 8:08pm PST, the phone charged an additional 7% to a total of 17% charged in ~5hours
And last, I tried charging it overnight while the phone is off. This morning it said 100%, but as soon as I turned the phone on the battery dropped to 45% and in a few minutes down to 28%
Now, I've searched and searched for solutions to similar problems but could not find any of which has any closely similar symptoms.
I love this phone so much, I thank everyone who will help in any way possible!
I'm in college and in dire need of this phone everyday! It's ruining my schedule/life!!!! :crying:

In settings > about phone > status does charging say AC or USB? If it's USB your charger may be bad. You can try changing chargers but you need a wall wart the same Amps as your stock charger which I believe is now 2.0A when older devices only used 1.0A. You can also go to dialer hit ##3282# > edit > enter MSL and then disable USB charging I forget which label it's under but if you peek around you'll see it. Just uncheck the box back out of dialer and reboot.

Thank you for your response, although unfortunately it says AC so that's not the issue as of the moment. Thank you though

Have you tried a differnt charger? Maybe your wall wart or cable are slightly off and not allowing proper current flow. The only other thing I can think of is its the battery or the hardware of the phone itself, so I say start with the charger/cable since its the cheapest

The only thing I can think of then is either the battery has a bad charging circuit or theres something wrong with your USB port/voltage regulator. Have you tried cleaning the USB port with compressed air and then a dab of 91%+ alcohol on a twisted up piece of paper towel to get any sticky gunk off of the contacts? Thats the last thing I can think of trying b4 jumping to switching batteries and then taking it to a repair center for them to test the phone itself.

Alright, I'll try those, thanks
Although I'm really leaning towards this being more of a problem with the software because of reason #1 on OP.

That was what originally had me thinking it was charging in usb mode. Cuz when im plugged into my pc and doing stuff it wont chsrge fast enough to keep up with the drain. Thag could also be a symptom of the voltage regulator being bad, not getting more power in than power out.

HOLY cheese-its. Cleaning the thing with twisted paper and hand sanitizer (as you said, but didn't have rubbing alcohol with me) yielded a result: it is now showing an estimated time before it is fully charged (wherein before, it was stuck at "calculating"). I'll be updating if there are any more progress
THANKS!

Thank my kids for gunking up my phones on the regular

WTF? Phone stopped charging all of a sudden

Hey guys,
I've had my GN for about a week now with absolutely no problems until tonight. I went to bed with my phone plugged up into the charger thru the wall and when I woke up it was still at 73%
Tried unplugging and plugging back it but the phone won't even detect that the charger is even plugged in. So I tried plugging it up to my computer and it still won't detect anything. The charger is still in perfect condition and I tried plugging into the car charger, but it will slowly charge.
you know when you plug in your usb cord to a computer or charger....that little icon on the top left pops up with the usb icon on the top left
well..i tried plugging in my phone to charge thru the outlet but it won't detect it so i took it out and tried to plug it thru the computer..but my cpu won't detect anything either
also
You know how when you plug it up to your computer and you hear that chime indicating that your has recognized it as a media dive. Well, my computer won't even pick it up / recognize it anymore
I've rooted this phone, but I've done nothing else with the phone. I rooted it last week, but did't have problems until last nite. It was charging just fine when I went to bed, but woke up and it just stopped charging
Just an obvious question so forgive me if you've already tried this. Have you done a battery pull to fully reset things and see if that helps? If it's a h/w problem it won't have any impact and probably means an exchange is in order.

Yeah I'm doing that right now. I completely took out the battery and put it back it back in with no luck
I've been using the extended battery. SO i took that one out and replaced it with the stock battery and still no luck
What if I already rooted teh phone?
This is my first smartphone ................. I'm so freakin nervous right now
Did you try different cables?

Would that mean it is a cable issue?
try pushing the cable upwards to see if it makes contact...i had a problem with my usb cable and had to change it.

you can always unroot the phone if you need to send it in. I would slightly jiggle the cable when charging, maybe its a loose charge port on the device itself.
Have you had a good look inside the phone's USB plug and the USB cable plug? There might be something stuck up inside one of them. If so, you can clean it up with 99% alcohol, or contact cleaner by dabbing some on a soft toothbrush and scrubbing it out. Phone off, battery out of course.

This phone is plastic! I wouldn't put 99% alcohol anywhere near it!

You press the tip bristles up inside the usb connector and flick downward, avoiding other areas. And the brush doesn't need to be drenched. Alcohol won't phase it unless you spill it all over the device, the alcohol quickly evaporates...considering alcohol comes in a plastic bottle.
i had this problem with my stock phone.. turned off phone and it would charge... i let it go to 100 and did battery pull and worked fine ever since

man, spoke to soon..... been a while since it happend , but now its happening again...
charging while phone is off seems to do the trick....
what is also wierd is that i plugged it in while the phone was off for about 5 mins and turned on the phone.... it went from 12% battery to 45%
I've just been charging it faced down. Where is the cheapest place I can buy a whole new charger?

[Q] Phone says that it's always charging?

I don't know how to go about this, because, to my knowledge, its not effecting the phone in any way. Maybe a little drain, but that could be 4.2's problem. But regardless, my phone is always "on charge" no matter where I am. On any ROM this happens, so I know its a physical thing. I've been told that you can use a knife to push the contact up a little, but that only works until I plug it back in the next day. So...... Any thoughts on how to fix this without replacing the charging port? (To my knowledge, that involves soldering very small parts.)

Well if it worked by bending the contacts up but goes back when you plug it in. Have you tried a different cable? Also have you cleaned out your charging port?

Agreed. At this point you could be having issues where you can't see it, such as where the port is connected to the board.
Had to take port completely off before i noticed... Sprayed with acid (not recommended) and cleaned it, rinsed it, soldered back in place = good to go..... For now

If you need to repair it go the this site. http://mobiletechvideos.mybigcommerce.com/samsung-epic-4g-touch-usb-port-repair/
You send it to them and they will fix it.
Turn around time is normally 5 to 7 days.
I mean. I guess i'll use it until it breaks. And even then, I use an external battery charger. So. Yeah....
Yeah i fixed mine.... I always end up fixing all my electronic problems... But i lost my charger so i still use a battery wall charger... Used my brothers charger to test my fix

Hi jeep, i have a similar problem but i'm not sure it's the same, i happened a few days ago when myi changed the battery and pugged in the charger, i noticed there was something strange, the phone's screen showed the battery was charging before i pugged in back (just when i placed the new battery). Now it behaves as it's always plugged in charging just when placing the battery in, the phones is turned off and the screen shows charging battery icon (i've tried 2 more batteries), and also there's no usb connection to the PC either.
It's a very bothering problem, the phons won't go into deep sleep, and the screen goes to the screensaver all the time (as it where pugged in charging)...
I always repair my own electronics, months ago i replaced the power button, do you think it could be a bootloader issue or just the micro-usb port?; when you fixed yours, do you think i should take it completely off and resolder?
Any advice will be really appreciated!!
Thanks

[Q] A100 Powers OFF when charger is connected.

Recently successfully replaced the LCD screen on my Acer A100. Device worked fine for some time after that repair. Wanting to get a secondary charger for use at work I went to radio shack. Sales "tech" tried several different adapters, found one that fit inside he port, but wiggled. She plugged it in but device wasn't showing a charge. Decided to order one from online. At home the device still would not charge with its own charger. Thought maybe the charger was faulty. Ordered two more. Still the A100 turned off when charger plugged in. Figured tech had burned out the a/c port. Ordered and installed a new one. Still A100 turns off immediately when charger is plugged in. I have 3 chargers now - same results with all 3. Have now ordered a docking station to utilize (hopefully) charging ability through 40 pin connector.
If this connection creates same shut down am I looking at a battery replacement? AM sitting at 33% battery level now, device shut down completely.
Acer wants 199.00 prepaid to submit to them for repair - this is more than I paid for the device! Not really an expense I am willing to pay if all it needs is a battery. There is no erratic behavior , just immediate shutdown as soon as a charger is connected. Any ideas?

If its doing it on 3 chargers its sounding more like a board charging circuit issue. You could remove the battery and then see if it behaves normally, that'll be battery or board right there. Or if you have a multi meter test output at the battery connector.

Don't have a multi meter. Tried connection via new docking station, got same response: device immediately shut off. Tried your suggestion, disconnected battery connected to docking station, got immediate shut off. Same with charger via a/c port. :crying: Mainboard is out? But Device responds and acts normal when in battery mode - or is this isolated to the charging circuit part of the main board?
Thanks for the suggestion!

Sounds like its tripping on the charger circuit and cutting out, like a breaker tripping. IMO look carefully for any shorts on the boards, even something stupid like dog hair can cause strange things to happen. A good blasting with air wouldn't hurt either. It could even be the dock port as it does charge from there and is subject to debris also.

Thanks again for more suggestions. Yup I have been over the board and all connections with a looking glass. Changed out the A/C dock port. My suspicion is that when the Radio Shack tech powered up the "Almost fits" adapter it blew whatever breaker the board has.
When I had it connected to the docking station with the battery disconnected, it powered on, then immediately shut off. So this definitely sounds like a "blown fuse". I completely disassembled and reassembled it again (except for the LCD screen) and checked all connections and plugs. Nothing visible to indicate a burnout or cross connection.
No odd smells either. Probably some teensy weensy transistor or resistor or something. I am not an electrician - just good at R & R.
Another visit to ebay and I am parting with 50 bucks for a "factory refurbished" motherboard. In the mean time, my beloved tablet will await further surgery. Will keep you posted. Board should be here by Saturday. I hope so - battery is down to 27%. Thanks again for weighing in!

To bad considering the crappy battery life so its not like you can charge some other way and swap the battery around.
Example, I have a bricked unit that charges but doesn't otherwise work, so I mean using my bricked board to charge it and the non charge board for use. The a100 isn't really a good setup for swapping around lol. I may actually be interested in that board now that I think about it...

If I could figure out a way to charge the battery OTHER than through the board - I would! Which got me to thinking. One COULD get a second rear panel, cut a door in it, install teensy weensy hinges or create a hinge with cloth tape. then make some sort of extension cord for the battery charging cord, plug it in to the "external" charging board and refill the battery that way.
With a working board and the right know how, one could just extract the board, put it in a box and make a charger out of it too.
But that is just my brain rattling around ideas. :silly: Hopefully this new "refurbished" mother board will do the trick and I will learn my lesson and NEVER let a sales "tech" attempt trial adapters! at 10 minutes to 9pm tonight it was in Texas....
Until I CANNOT use it, I didn't realize how MUCH I used this little tablet!
now it blinks orange?
Oh fer cryin out loud! The motherboard has arrived, I have installed it. Can plug n the charger and drop it onto the docking station and now I get the same response for both charging options: Charge LED lights up orange solid for just about 60 seconds, then begins blinking. Device doesn't respond when power button is pushed UNLESS it is plugged in, and then it just sits at the "ACER" screen.led changes to blue.
OK, wait a minute, this is the third time I have turned it on while plugged in. Acer screen has moved to Android, Device has started. Battery icon showing a question mark. 23%
Turned off, turned back on, now battery shows only 3%????
Think I saw something on the forums about that. will go on a quest.
Finally charging again!
Shhh, don't want to disturb my device....
Found folks on other forums with similar issues of the Acer A100 tablet showing only 3% charge. I removed and inserted the charging pin several times, the device would show solid orange led for about one minute then start blinking. Turned the device on when charger plugged in, unlocked the screen, then with device still plugged in I shut it down completely. Removed charger. Plugged it back in and so far the led is staying at solid orange.
Please keep your fingers crossed for me! This has been quite the roller coaster ride of discovery. Will leave it be for overnight (what is left of the overnight). Then peek at it in the morning. With any luck at all it will have accepted a full charge and I will be greeted with a functioning device! I almost want to learn a new trade..
well now that is weird, got up this morning to a nice blue charge indicator. Yay! Unplugged charger, press on button, hold, hold, hold, hold, hold and device does not start up. Dang it! Plugged it back in, led went solid orange, then started blinking again! Pressed and held on button. Device came on. battery meter shows 3% and a question mark! HUH?
have device plugged in, settings of course show android version 3.2.1 for this motherboard. Guess I need to upgrade it to ICS maybe that will resolve this weird battery issue? Hope soemone here has ideas, feels like I am soooo close to resolving this.
I read the upper posts.
Now I want to share my experience regarding battery load sharing:
I have allso problems to charge the battery.
I have on my tab, for example, 40% of battery power.
I turn my tab off.
When i plugged the charging cable in it shows me the orange led for load.
After two hours or more i turned the tab on.
It shows me not more than 40% but only 37% or so.
So not loaded. This was a bad sign....
I dont no was happend.
I get a little bit nervous but when the tab not get power it doesnt work....
After two/three hours the battery was empty.
Now i can only start my tab while plugged the charging cabel in because the battery will not load.
I have tried several options to find a solution (disconnect the battery, install a new battery, etc. ....).
My solution was fairly straightforward:
I open the tab. Look where the power comes in.
Of the charging socket go four (two red and two black) cable to the motherboard and from the motherboard it goes seven (two red, two black and for me not so important three other coloured cabels) to the battery.
I organized four thin wire and soldered it from the charging socket directly to the battery (of course red to red black to black ).
The result:
When i plugged the charging cabel in while android is running i get no information to load and it shows me not to.
But when i turned the tab off and on again it shows me that it has the battery charged :fingers-crossed: .
After on night while the charger plugged in the battery is fully loaded!!
And of course i get the information in android the discharging of the battery but this is an normaly thing!
So, the problem to load the battery for me is solved .
I hope it helps a little bit for everyone!

I really hope other isn't any voltage or amperage changes needed of that can blow that battery up real quick, plus it can't stop charging, you'll need to monitor that yourself.
Thanks for the info though, it does appear to be yet another somewhat common bug these have that can be addressed by a user if they feel the need to.

Not switch the charger off when the battery is full?
I think the charger there is a shutdown would otherwise overload the battery, right?
Or do this the motherboard?
Anyway, for me the tab is fully working now and if the battery is broken, it is not a big expense to replace them .

I was saying the board is in charge of cutting the battery charge off, not the charger itself so maybe keep an eye on it, its a good way for an explosion or fire.

Wiring the battery direct to the charging port- I would definitely worry about burning up the battery or causing a fire - especially while charging when I sleep. I have had more than my fair share of run ins with fire.
The Motherboard I ordered arrived and I installed it. It was listed as "factory refurbished", but unfortunately will not accept a charge. I thought it had charged overnight at one point, but all it does is blink orange and the battery reads 3% or 0%. Turning the device off when plugged in and doing a reset has not helped. The vendor has been gracious to do a replacement, so I will follow that route until I get a working motherboard.
I have discovered that the docking station will be a welcome addition to my Acer tablet paraphernalia! Although this model docking station isn't the one that allows HDMI throughput, it still will be nice for music, and other media. A Bluetooth keyboard and the tablet will offer yet another computer tool!
First things first though, get the tablet to accept a charge - until then it is a really wide flat paper weight! I am getting VERY adept at opening the tablet and removing the internals!
It is working again! The motherboard sent was defective but vendor issued an RMA. Received the replacement yesterday, installed it last night. Charged over night and fully functional this morning! Ahhh it feels good to have my little buddy back again. Didn't realize how much I used it, until I couldn't use it! Thanks to all for the help.

[Q] Charging problem, tried the following...

Ok so a little of background story, if you don't care about it just skip to the next paragraph. I bought my T989 over the internet, it was working perfectly. I wanted to make the most of it, rooted it and tried Swapper 2, which hard bricked my phone. I'm not new to rooting, I've rooted some phones now, but I had never tried swapper, I liked the idea of unoccuping some RAM memory. Apparently I did something to my boot sequence thing and my phone was dead. I still had waranty on the phone (one week left when that happened so it is suspicious to anyone) so I called. After one hour of arguing over the phone and trying to convince them it wasn't my fault, which of course I knew it was, they decided to send me a new one... ahem "new" one.
Ok so here's where the priblem start. My "new" phone was working alright untill it stopped charging, didn't work AT ALL. I took a peek and one of the pins on my phone was bent, it was upwarda and as I tried to get it back to its place it fell off. I took my phone to get the MicroUSB replaced andsure enough they did.
My phone was charging again correctly. It was doing great untill it stated to charge slower and slower. It got to the point where it just shows as charging, but doesn't charge at all.
I've tried everything, I bought a new original Samsung battery, still same issue. I downloaded an app to tell me the amps the cellphone was pulling and it shows 350-450 when I have read it needs minimum 600. I have tried custom roms, kernels and nope, still pulling 400, tried LG chargers, Motorola chargers, a SAMSUNG S3 charger and still no luck. The thing they all have in common is that they're USB chargers so I read if the cellphone detects it as such it would give me a hard time.I've tried making a fast charge USB cable with a video on Youtube but it still only charges 400 mAmps. I've installed custom kernels with the "USB fast charge" and STILL no luck.
The ONLY thing I haven't tried is using and ORIGINAL, Samsung wall charger but at this point, I think it won't fix my problem because of the fact that I remember it worked well in the beggining. I am currently charging both batteries with a Universal Battery charger, but I've read that they wear out batteries throughout time.
So, is there another thing I haven't tried... or is my cellphone doomed now? I believe that it's the phone, as in the mother board if I can call it that, or does anybody have another theory?
Thanks for your time, would love to see anyone suggest

I know this isn't an answer but a general comment. This is a good reason why I will NEVER buy electronics that are used or from a retailer that isn't a big name. I don't care what the seller says there is just really no way to know exactly what you are getting. If you had bought this phone from Amazon (direct) you could have already got another one by now with no arguments. I'd be looking for another phone and call it a loss.

Thanks dude, I know it really matters on where you buy it, but the price was just so handsome to me. I guess that's what I get and as things like this happen you learn more and more on what you buy and what you decide to do with them. I guess I already consider it as a loss but I'm aware that it's not unusable yet. I guess I will continue to charge both my batteries with the charger, but I was just curious to know what really happened to the phone to avoid things like this in the future

What apps do you all have installed on your phone and running while you are charging it? Try making a full backup then do a clean install of your ROM (backup just in case this doesn't fix it). After doing this do NOT install any apps, just test charging. If charging works, it is some app on your phone. I know those "battery saving" apps can eat up a lot of battery if configured wrong. And if you have a lot of background apps running, they can eat your battery without you knowing and reduce charging time.
Go into settings->device and check what is eating up your battery there before charging and during charging.
If you don't want to re-install your ROM, try charging your phone with the screen off (no screensaver (daydream) or nothing, just screen off, charging) and in airplane mode. I recommend doing a clean install to see if it is some apps (you can use TB to back everything up, then do the clean install and test from there).

The ROM I currently have has a great battery saving mode, I also have "Advanced Task Killer" to kill any apps. It's the same issue. I want to buy a new charger but I still think that won't fix my problem. I've also charged in Airplane mode and no luck

Can you go into settings->Battery and post a screenshot of it? I'm curious as to what is eating up most of your battery.
After, I would still try doing a nandroid and flash your rom cleanly and install 0 apps and try charging on this clean install. I know my friend ended up getting some battery optimization app installed (which she claims she never installed, but it is on her phone) and her charging times were horrid. It also made the phone quite laggy. I imagine if you got 2 or so of these types of apps on your phone, it could eat your battery instead of charging it.
Also, when you charge it, it is a strict charging cable not a MHL adapter right? I know when I have my MHL cable hooked up to my phone it claims it is charging, but it actually drains the battery slowly. (MHL is micro USB -> HDMI).
Since you have tried multiple chargers and cables, I would be looking at the phone as being the problem. Also, look at the contacts on the bottom of the phone and look for any bent pins. I wouldn't try to fix that yourself, but if they are bent, I'd take it in for repair. those pins are very fragile once bent and can break off if not handled very carefully after they are bent.
If you can get into adb from your phone to PC, then the pins on your phone should be good and the USB cable should be good. Does it charge if you put it in fast charge and plug it into your PC?

The pins are alright. As I stated, I recently changed the MicroUSB port, well I paid somebody to do it and it was working fine at first but then stopped charging, well, not stopped charging actually. At first it started to charge slower and slower untill it got to the point that it just says it's charging but it doesn't charge. It COULD be to the fact that I flashed new ROMs, downloaded games and all but I doubt it since now I have a brand new ROM with no games (or not that many) and you can see from the screenshots I uploaded that nothing's eating my battery
Well except for my screen, I had it at 80% brightness lol. Usually I set the brightness at the lowest (no Auto brightness to save battery) and my wall paper is color black since I heard Samsung phones do save up battery with black since it doesn't light the LEDs or something like that.
And yes, it's strictly USB cable. When I activate "Fast charge" and if I connect the phone to the computer it just shows the notification "USB connected" for a second and then disapears.

the screenshots attached were helpful. I don't see anything in that list that looks like a huge battery sucker and since you say your rom is fairly fresh and clean, it likely isn't the apps. Are you sure the guy who swapped the microUSB port did it correctly? Improperly soldered pins (especially those tiny ones on a microUSB port) can be tricky to solder correctly if you don't have the correct tips. It could also be that something else got damaged while putting that on (if the capacitors were not properly discharged before replacing the microUSB port, they could have gotten damaged).
I think that your assessment that it is one of the boards (likely the charging circuit) got damaged. I'd go back to the guy who replaced the port and get him to check the charging board (specifically the capacitors) to see if there is any signs of damage or wear. Capacitors can get damaged really easily if the heat on the iron was set too high. I know I've damaged capacitors while soldering things before. Or it could be that the port didn't get a solid solder connection or ended up briding some pins. If fast charge is on, your PC shouldn't see a USB device being plugged in. If you have a multimeter, you could check the resistance on the 4 USB pins and see if any of the pins are bridged.

Well I took it to the guy from before and he couldn't find a problem with the phone's soldering, but even he wasn't sure what the problem was as if it's not his specialty. I do not have a multimeter :/
I was thinking taking it somewhere else and have them change my microUSB port to see if that other person might now a bit more. I'm sorry but I'm more of a software type of person, I clearly have no clue what the problem might be
THANK YOU for really helping me and taking your time to analyze my question, I really appreciate it thanks man
So if what you say is true, do you think it can still be fixed?

It definitly can still be fixed, it'll just be tricky. If they are surface mount capacitors, which they likely are, it is hard to tell when they go.

So what I should tell them to do is to change the capacitors? I can leave the same miniUSB port right?

I would tell them the symptoms and let them tell you what they think should be fixed. In my mind it is likely the capacitors on the charging board that need replacing, but without having the hardware physically in front of me and hooked up to a multimeter, I cannot say for certain. It could be a faulty microUSB port or a bad pin (bridged or microfractured), could be damaged PCB trace, could be gremlins
I would bring it in somewhere or give it to somebody and tell them that the phone doesn't seem to be taking a charge and ask them if they can look at it. If it is still in warranty, send it to Samsung to get fixed. If it is outside of warranty, take it to somebody who knows their stuff (likely a professional repair shop OR somebody who does cell phone or PCB repair for a living... hobbyists may be able to fix it, but to me this sounds like something that somebody with training should likely look at).
Since you have tested different AC adapters (including known-good ones) and different cables (including known good ones) and charged the battery outside of the phone, that narrows the problem down to being something with the phone. You narrowed down it is likely not software related, so that leaves hardware. I know from experience soldering very small components can cause bridges quite easily; even when done by the pros. Some bridges don't matter, but it is better to avoid solder bridges whenever possible. I know I had to replace my nintendo DS slot-1 due to a busted pin and soldering that thing with a large iron was a pain in the behind. Got it all fixed, but it was not an easy task.

Glad I can help. I used to work professionally soldering tiny components before moving into IT. Done some hardware mod to a few cameras, repaired a ps2 controller, have an old tube amp going fix soon too. I've seen a lot of weird things happen with bad solder joints or faulty capacitors.

charging issue

is there anyone with problems charging the t320?
it goes fine until 40%, above that or stops charging or is really slow, like 1% in one hour.
i thought it was a rom issue, so i flashed the original rom from sammobile
the charging at this moment is 56%, 150mA average, when isn't negative - 200
this is stock usb and charger, and also with other charger/cable is the same
Me too

I was just searching the forums as bought mine yesterday and have a similar problem, mine got to 56% then stopped charging. If i turn off the tablet it does start to charge again so will fully charge with it powered down and see what happens.
soon i'll be testing another charger
you can see the charging voltage on the galaxy charging current available on playstore
most likely i will use warranty

Pop the back off gently and disconnect the battery from the main board. When you reconnect it, let it charge up fully before turning it back on. After this, it will behave normally for the rest of time.
Thanks

Thanks for the reply but it seems my issue was caused by a faulty outlet socket. The socket works fine for everything else but would only charge the tablet when it was powered down. Tried charging off my laptop and desktop usb and it was the same, but tried some other outlet sockets and they charge fine. I understand the usb outlets might not provide enough to charge the tablet but hadn't considered the socket as I know it works, must be just enough high resistance to prevent it charging a working tablet but provides enough current to charge it when it's powered down. The fact it was showing a 56% charge was just co-incidence.
Thought it might be worth posting this as it's not something I've come across before.

Here's the thing. When mine was misbehaving I could get it to start charging again by switching outlets or even reversing polarity on the wall plug. It was a temporary fix as within days the problem would be back. I thought I had it fixed so many times. It always came back. If it happens to you again just remember the above post. It's been four months since I did it and never once has it been quirky. Something in the hardware needed reset that only disconnecting the battery could do.

It's the faux leather thing you pry off. Keep the angle that you pull on the cover shallow and work it slowly.

with no other solution i did too pop the back off gently and disconnect the battery from the main board, now it's working OK, let's see how long
cabel pull
hoping this works. I just filled out a warranty email today for same issue on 12.2 Tab Pro. It pried the case open with a credit card. Very slow, took about 7 minutes. Pulling the power cable in the middle, probably behind green tape. Use needle nose pliers or something small behind the wires and pull up. The pins are tiny and will f*ck the whole thing up if bent.
I get the feeling that the screen turns itself on even when eye tracking settings are off or closed in case. I hear the annoying sound at night when charging. Why Sammy does not have a smart current sensor built in is insane. Asking you to unplug when most people will leave on and charge overnight. Just dumb.
I can't get past 57% charging for last 2 weeks. Stock, unrooted for first time in a long time, so I am pissed to hear ROM had not effect. This is likely undocumented hardware issue Sammy doesn't want to admit to.
even on my T325 I had the same problem but I solved it this way ...
I have worn the battery completely until turn off my device, I loaded the battery overnight to device OFF.
wipe and install rom custom samsung
I launched and used app "battery calibraton" (root)
I have now done 4 cycles of charging to 1600/1750 mA

even on my T325 I had the same problem but I solved it this way ...
I have worn the battery completely until turn off my device, I loaded the battery overnight to device OFF.
wipe and install rom custom samsung
I launched and used app "battery calibraton" (root)
I have now done 4 cycles of charging to 1600/1750 mA

There is no need for physical interventions on the hardware, maybe someone does not know in depth the behavior of lithium ions

Perhaps not, but I and MANY others have encountered the same problem. Across multiple Roms, fully discharging and recharging, running the so called calibration apps. Rebooting, unpluggin, replugging. The problem NEVER fully went away. It would work for a charge cycle or two or three, then would reappear.
I finally took the back off, unplugged and replugged the connector., closed up the case, charged it for several hours before turning it back on.
Not ONCE has the problem occurred since that intervention. That was over a month ago.
Maybe it's not lithium ion behavior, it might be in the charging circuit and hardware.
If you have a suggestion, then by all means share it so others can solve their problem.

I've already written how I solved the problem, but in 5 years and dozens of Android rom installed on various devices, this problem for me was very frequent.
Always the same. On my ST325 I solved like other times in the past.
No news I found on this battery, battery charger of the same problems since I know Android

sorry for my bad English ...
for this device I've tried all the roms available (CM11 or not)
the problem is very acute especially after CM11> Pro Plus V2, but the problems had already occurred some time with the various installations buil CM11
about a week I did the operation described above (already done in the past even on my previous samsung device, Note 1, Galaxy s4, Galaxy Mega, Galaxy tab 3 g3 ) with the same result ...
The battery charges very quickly with the device ON to 1700 mA (monitored with "Monitor battery widgwt pro")
again sorry for my english
